To examine the population impact and effectiveness of the Pro-Change smoking cessation course based on the Transtheoretical Model (TTM) compared to standard self-help smoking cessation literature.
                Randomized controlled trial.
                Sixty-five West Midlands general practices.
                Randomly sampled patients recorded as smokers by their general practitioners received an invitation letter and 2471 current smokers agreed.
                Responders were randomized to one of four interventions. The control group received standard self-help literature. In the Manual intervention group, participants received the Pro-Change system, a self-help workbook and three questionnaires at 3-monthly intervals, which generated individually tailored feedback. In the Phone intervention group, participants received the Manual intervention plus three telephone calls. In the Nurse intervention group, participants received the Manual intervention plus three visits to the practice nurse.
                Biochemically confirmed point prevalence of being quit and 6-month sustained abstinence, 12 months after study commencement.
                A total of 9.1% of registered current smokers participated, of whom 83.0% were not ready to quit. Less than half of participants returned questionnaires to generate second and third individualized feedback. Telephone calls reached 75% of those scheduled, but few participants visited the nurse. There were small differences between the three Pro-Change arms. The odds ratio (95% confidence intervals) for all Pro-Change arms combined versus the control arm were 1.50 (0.85-2.67) and 1.53 (0.76-3.10), for point prevalence and 6-month abstinence, respectively. This constitutes 2.1% of the TTM group versus 1.4% of the control group achieving confirmed 6-month sustained abstinence.
                There was no statistically significant benefit of the intervention apparent in this trial and the high relapse of quitters means that any population impact is small. This study examines the efficacy of targeted versus standard care smoking cessation materials among urban African American smokers. Five hundred smokers (250 to each group) are randomized to receive a culturally targeted or standard care videotape and print guide. Both groups receive 8 weeks of nicotine patches and reminder telephone calls at Weeks 1 and 3. Process outcomes include material use and salience at 1 and 4 weeks postbaseline. Smoking outcomes include 7-day abstinence, smoking reduction, and readiness to quit at 4 weeks and 6 months postbaseline. Despite greater use of the targeted guide (68.8% vs. 59.6%, p < .05), intervention participants do not perceive the targeted materials as more salient, and no significant differences are found between groups on the smoking outcomes. Findings point to the importance of greater audience segmentation and individual tailoring to better match intervention materials to the needs of the priority population. In a unique approach to utilizing an existing intervention, "opportunistic" and targeted school-based strategies were used to enroll 446 adults into a tailored preventive health program featuring a health screening and smoking-cessation intervention. Implemented through a public school district serving a multi-ethnic low-to-middle income urban community, subjects in this randomized trial were interviewed at enrollment and at three-, six-, and 12-month follow-up, and rescreened at 12 months, to assess changes in smoking-related knowledge, attitudes, and practices. Using conservative assumptions, self-reported ever-quit rates and continuous abstinence rates of 57.5% and 2.6%, respectively, were achieved across groups; point-prevalence abstinence rates were 13.2%, 12.9%, and 10.3% at three, six, and 12 months. The study examines issues relevant to smoking status and stages of change in this population. The role of the school in increasing access to needed health programming in underserved communities is explored. Radon and cigarette smoking have synergistic effects on lung cancer, even when radon concentrations are relatively low. Working through an electric utility company, we sought to reach smoking households with low radon concentrations and motivate smoking cessation or prohibiting smoking in the home.
                Eligible homes (n = 714) were randomised to receive: (1) the Environmental Protection Agency's (EPA's) "A citizen's guide to radon"; (2) a specially developed pamphlet; or (3) that pamphlet plus brief telephone counselling.
                Utility company "bill stuffers" offered free radon test kits to smoking households. All households received radon test results with an explanatory cover letter. Both the specially developed pamphlet and the telephone counselling emphasised that smoking cessation or prohibiting smoking in the home were the optimal risk reduction strategies. Households were followed up at 3 and 12 months after receiving materials.
                The specially developed pamphlet and the EPA guide yielded similar outcomes. There was a non-significant trend for telephone counselling to produce greater sustained quitting than the specially developed pamphlet, and phone counselling led to significantly more new household smoking bans.
                Working through a public utility company is an efficient way to reach smoking households, and brief telephone counselling is a promising method for promoting household smoking bans and cessation in homes alerted to the risk posed by the combination of radon and smoking. This study compared interactive and noninteractive smoking cessation interventions for a population of smokers who were all members of 1 division of a managed care company. In addition, it examined whether a dose-response relationship existed. Screening was completed for 19,236 members who were contacted by telephone or mail. Of the 4,653 who were identified as smokers, 85.3% were enrolled. A 2 Intervention (interactive or noninteractive) x 4 Contacts (1, 2, 3, or 6 contacts) x 4 Occasions (0, 6, 12, and 18 months) design was used. The interactive intervention was stage-matched expert-system reports plus manuals; the noninteractive intervention was stage-matched manuals. Contact occurred in 1 of 4 series (1, 2, 3 or 6 contacts) at 3-month intervals. The expert system outperformed the stage-matched manuals, but there was no clear dose-response relationship for either intervention. Few smoking cessation self-help materials are available for smokers who are not planning to quit. However, computer-tailored interventions can be designed specifically for these smokers.
                In a large randomized field trial (N = 843), two different tailored smoking cessation self-help interventions (multiple tailoring and single tailoring) and one standardized smoking cessation self-help guide were compared with a no-information control group and with each other. The contents of the tailored interventions were adapted to individuals' self-reported stage of change, outcome expectations, self-efficacy levels, and smoking behavior.
                The primary outcome measure was forward stage transition. The standardized self-help guide had no effect. Among smokers who were not planning to quit within the next 5 years the multiple-tailored intervention was more effective than the single-tailored intervention. This pattern was supported by the cognitive changes caused by the interventions. Among smokers who were planning to quit within the next 5 years but not within the next 6 months, none of the self-help materials had any effect.
                The present results show that the self-help material currently available in the Netherlands, the standardized self-help guide, was not effective among smokers with low readiness to change. However, computer-generated tailored interventions seem a promising means of communicating information on smoking and smoking cessation to these smokers. A total of 424 smokers were randomized in a 2 x 2 factorial experiment. A pharmacologic factor contained 2 levels: transdermal nicotine path (TNP; 21 mg) and placebo. A self-help behavioral treatment factor contained 2 levels: video-enhanced self-help treatment manual and self-help treatment manual only. At 2 months, TNP produced a higher level of abstinence (36%) than placebo (20%), p < .001. No other comparison was significant. In secondary analyses, (at 2 months) and compliance with patch treatment regimen (at 2, 6, and 12 months) were associated with less relapse. Although nicotine replacement therapy has improved our ability to produce smoking cessation, the production of sustained, longer term abstinence remains an elusive goal. Smokers (N = 756) were randomly assigned by stage of change to (a) standardized self-help manuals (ALA+ condition), (b) individualized manuals matched to stage (TTT condition), (c) interactive expert-system computer reports plus individualized manuals (ITT condition), or (d) a personalized condition with 4 counselor calls, stage manuals, and computer reports (PITT condition). Over 18 months, the ITT group's results more than doubled those of the ALA+ group on abstinence measures. The ALA+ and TTT conditions were equivalent over 12 months, but at 18 months the TTT condition was more effective. The ITT condition was the best or comparable with the best treatment at all follow-ups for smokers at all stages of change. Results suggest that an effective expert system has been developed, and discussion focuses on delivering this system to entire populations of smokers. Radon and cigarette smoking have synergistic effects on lung cancer risk. Electric utility company bill stuffers offered free radon test kits to households with at least one smoker. Participating households (n = 1364) were randomized within a 2 x 2 design to evaluate the main effects of brief telephone counseling and a targeted video on smoking cessation and the establishment of new household smoking bans. Phone counseling was associated with cessation at 3-month follow-up but neither intervention led to 12-month or sustained cessation. While neither intervention had a significant effect on new bans, there were trends in the predicted direction and the combination of the two significantly increased new bans compared with no intervention. The presence of children in the household was associated with new bans. While few households had high levels of radon, such levels were associated with radon mitigation behaviors. Together with a previous study, these results suggest radon risk is a useful and inexpensive way to engage smoking households in risk reduction behaviors, especially the institution of household smoking bans. A stage-matched expert system intervention was evaluated on 4144 smokers in a two-arm randomized control trial with four follow-ups over 24 months. Smokers were recruited by random digit-dial calls, and 80.0% of the eligible smokers were enrolled. Individualized and interactive expert system computer reports were sent at 0, 3, and 6 months. The reports provided feedback on 15 variables relevant for progressing through the stages. The primary outcomes were point prevalence and prolonged abstinence rates. At 24 months, the expert system resulted in 25.6% point prevalence and 12% prolonged abstinence, which were 30% and 56% greater than the control condition. Abstinence rates at each 6-month follow-up were significantly greater in the Expert System (ES) condition than in the comparison condition with the absolute difference increasing at each follow-up. A proactive home-based stage-matched expert system smoking cessation program can produce both high participation rates and relatively high abstinence rates. Personalized feedback and a financial incentive, developed from an intrinsic/extrinsic motivation framework, were evaluated as adjuncts to self-help materials for smoking cessation. Ss (N = 1,217) were randomized to 4 treatment groups and were followed up at 3 and 12 months. Consistent with hypotheses derived from the motivation framework, the financial incentive increased the use of self-help materials, did not increase cessation rates among program users, and was associated with higher relapse rates among those who did manage to quit. The personalized feedback increased both smoking cessation and use of the materials 3 months after distribution of the materials. Continuous abstinence (abstinence at 3 and 12 months) in the group that received the personalized feedback alone was twice the rate of the other groups. Previous research has demonstrated the efficacy of an interactive expert system intervention for smoking cessation for a general population. The intervention provides individualized feedback that guides participants through the stages of change for cessation. Enhancing the expert system by adding proactive telephone counseling or a stimulus control computer designed to produce nicotine fading could produce preventive programs with greater population impacts.
                Four interventions were compared: (a) the interactive expert system intervention; (b) the expert system intervention plus counselor calls; (c) the expert system intervention plus the stimulus control computer; and (d) an assessment only condition. A 4 (intervention) x 4 (occasions) (0,6,12, and 18 months) design was used. Smokers were contacted at home via telephone or mail. The initial subject pool was the 24,178 members of a managed care company. Screening was completed for 19,236 members (79.6%), of whom 4,653 were smokers; 85.3% of the smokers were enrolled.
                Thirty-eight percent were in the precontemplation stage, 45% in the contemplation stage, and only 17% in the preparation stage. At 18 months, the expert system resulted in 23.2% point prevalence abstinence, which was 33% greater than that of assessment only. The counselor enhancement produced increased cessation at 12 months but not at 18 months. The stimulus control computer produced no improvement, resulting in 20% worse cessation rates than the assessment only condition.
                The enhanced conditions failed to outperform the expert system alone. The study also demonstrated the ability of the interactive expert system to produce significantly greater cessation in a population of smokers than assessment alone.
                Copyright 2000 American Health Foundation and Academic Press. Most smokers attempt to stop smoking without using help. We evaluated the efficacy of a decision aid to motivate quitters to use efficacious treatment. SETTING AND PARTICIPANTS, A total of 1,014 were recruited from a convenience sample of 3,391 smokers who intended to quit smoking within 6 months. DESIGN AND Smokers were assigned randomly to either receive the decision aid or no intervention. The decision aid was expected to motivate quitters to use efficacious cessation methods and contained neutral information on treatment methods, distinguishing between efficacious and non-efficacious treatments. MEASUREMENTS Baseline questionnaire and follow-ups were used 2 weeks and 6 months after the start of the intervention.
                The decision aid increased knowledge of cessation methods and induced a more positive attitude towards these methods. Furthermore, 45% reported increased confidence about being able to quit and 43% said it helped them to choose between treatments. However, no clear effect on usage of treatment aids was found, but the intervention group had more quit attempts (OR=1.52, 95% CI 1.14-2.02) and higher point prevalence abstinence at 6-month follow-up (20.2% versus 13.6%; OR=1.51, 95% CI=1.07-2.11). CONCLUSIONS An aid to help smokers decide to use efficacious treatment when attempting to quit smoking had a positive effect on smoking cessation, while failing to increase the usage of efficacious treatment. This finding lends support to the notion that the mere promotion of efficacious treatments for tobacco addiction might increase the number of quit attempts, irrespective of the actual usage of treatment. The incremental effects of (a) a self-help booklet alone, (b) self-help booklet with computer-generated personalized feedback, and (c) self-help booklet, personalized feedback, and outreach telephone counseling were evaluated in a population-based, nonvolunteer sample of smokers. Smokers (N = 1,137) were identified through a telephone survey of a random sample of 5,903 enrollees in a health maintenance organization and randomized to a no-treatment control group or 1 of the 3 intervention conditions. Smoking status was ascertained 3, 12, and 21 months postrandomization. Cotinine validation of self-reported cessation was obtained at the 12-month follow-up. Overall, the telephone counseling significantly increased smoking cessation at the 3-month follow-up, but not at 12 or 21 months. Among smokers who were precontemplative at baseline, telephone counseling significantly increased prevalent abstinence at 3 and 12 months and continuous abstinence at 21 months (defined as self-reported abstinence at 3, 12, and 21 months). nan Smokers requesting self-help materials for smoking cessation (N = 2,021) were randomized to receive (a) an experimental self-quitting guide emphasizing nicotine fading and other nonaversive behavioral strategies, (b) the same self-quitting guide with a support guide for the quitter's family and friends, (c) self-quitting and support guides along with four brief counselor calls, or (d) a control guide providing motivational and quit tips and referral to locally available guides and programs. Subjects were predominantly moderate to heavy smokers with a history of multiple previous quit attempts and treatments. Control subjects achieved quit rates similar to those of smokers using the experimental quitting guide, with fewer behavioral prequitting strategies and more outside treatments. Social support guides had no effect on perceived support for quitting or on 8- and 16-month quit rates. Telephone counseling increased adherence to the quitting protocol and quit rates. African Americans remain a critically underserved group for smoking cessation interventions. This study tested the effectiveness of a tailored, culturally sensitive intervention for African American smokers who called the NCI Cancer Information Service (CIS) for help to quit smoking.
                This paper presents results of a 2-year study of tailored counseling strategies among African American smokers (n = 1,422) who called four regional CIS offices in response to a radio-based media campaign in 14 communities. Callers were randomly assigned to receive either the standard CIS quit smoking counseling and guide (Clearing the Air) or counseling and a guide (Pathways to Freedom) tailored to the quitting needs and barriers of African American smokers. Callers were predominantly female (63.6%). ages 20-49 (88%), with a high school education or more (84%). Median smoking history was 17 years; median smoking rate was 20 cigarettes/day. Standard (n = 689) and Tailored (n = 733) group subjects did not differ on most baseline measures.
                On most measures, Standard and Tailored counseling/guides received similar ratings, but the Tailored guide was rated as having more appealing photos (P = 0.001) and as being more appropriate for family members (P = 0.003). Six-month follow-up with 893 subjects (response rates were 63% Standard, 62% Tailored, ns) showed significantly more quit attempts (P = 0.002) and greater use of prequitting strategies (P < 0.05) among Tailored than among Standard subjects, but no differences in self-reported 1-week abstinence (14.4% Standard, 16.2% Tailored) (ns). An opportunistic 12-month follow-up of subjects recruited in the last year of the study (n = 445) (response rates were 57% Standard, 60% Tailored, ns) showed a significantly higher quit rate (15.4% Standard, 25.0% Tailored) for Tailored subjects (P = 0.034).
                Results show promise for tailored approaches to boost quit attempts and success rates among African American smokers.
                Copyright 1998 American Health Foundation and Academic Press. Examine the effects of three iterative tailored feedback letters addressing smoking; physical activity; and fruit, vegetable, and fat intake, and test the additional effects of providing feedback on action plans.
                A tailored, print-based intervention was developed and tested in a randomized control trial with a posttest after 9 months.
                A total of 2827 respondents agreed to participate. They were recruited from a random sample of 35,000 addresses obtained through the Dutch national telephone company.
                The mean age was 49 years, and 55% were female. Intervention. The experimental group received three printed tailored letters, and the control group received three printed generic letters. Respondents from the experimental group randomly received either a third letter with tailored information or tailored information and action-planning feedback. MEASURES; The questionnaire assessed physical activity; smoking; consumption of fruit, vegetables and fat; motivational determinants; action plans; and demographics.
                Tailored information resulted in more improvement over time than generic information for the intake of fruit, vegetables, and fat and for physical activity. No differences between the conditions were found for smoking because of high cessation rates in all conditions. Action-planning feedback did not increase the effects.
                Tailored lifestyle information can be effective for adults in changing nutrition behavior and physical activity. nan This worksite study assesses the relative effectiveness of three smoking cessation programs. Computerized medical files indicated that 29% of 13,171 employees were current smokers. Of smokers responding to a worksite-wide survey, 79% indicated interest in a smoking cessation program; 402 smokers agreed to participate and were randomly allocated, within their preference for a group or self-help approach, to the three different programs. Overall, 11% of smokers participated, an excellent rate for a large worksite. Participants were followed for 12 months (91% follow-up). Smokers in the group preference had better short-term results than did those following the self-help approach. The Multiple Component Program had 61% who quit, the Relapse Prevention Program had 37%, and the American Cancer Society Quitter's Guide had 12%. Long-term quit rates ranged from 16% to 26%; all groups exceeded the usual spontaneous quit rate of 5%. This study evaluated the effectiveness of nicotine chewing gum in smoking cessation, when incorporated into a behaviorally oriented self-help program. One hundred ninety-seven patients were randomly assigned to nicotine gum with a self-help manual, a self-help manual without gum, or a control condition, but received no further treatment from the prescribing physician. At six weeks, the nicotine gum group was superior to both the self-help and control conditions. By one year, many gum patients had relapsed, and the treatment effect was no longer significant. Patients who were able to quit initially were most likely to remain ex-smokers in the self-help condition. The clinical importance of these findings is discussed. At two chest clinics 1206 cigarette smokers referred by their general practitioners for chest radiography only either were dealt with in the normal way or in addition were given a How to Stop Smoking booklet by the clinic receptionist or nurse. Follow up one year later showed that 3.2% of all patients had successfully given up smoking, older patients doing better than younger ones and men doing better than women. Overall 3.9% of the group receiving a booklet were successful compared with 2.7% of the controls (p = 0.14). At one clinic the groups were not well matched for age but at the other, where there was no such imbalance, there was a suggestion that the booklet group did better than the controls (6.5% v 2.7% success), although the difference did not achieve conventional statistical significance (p = 0.09). If this can be confirmed as a real effect then this cheap, simple strategy could easily be applied on a large scale. To develop and evaluate, in a primary care setting, a computerised system for generating tailored letters about smoking cessation.
                Randomised controlled trial.
                Six general practices in Aberdeen, Scotland.
                2553 smokers aged 17 to 65. Interventions: All participants received a questionnaire asking about their smoking. Participants subsequently received either a computer tailored or a non-tailored, standard letter on smoking cessation, or no letter.
                Prevalence of validated abstinence at six months; change in intention to stop smoking in the next six months.
                The validated cessation rate at six months was 3.5% (30/857) (95% confidence interval 2.3% to 4.7%) for the tailored letter group, 4.4% (37/846) (3.0% to 5.8%) for the non-tailored letter group, and 2.6% (22/850) (1.5% to 3.7%) for the control (no letter) group. After adjustment for significant covariates, the cessation rate was 66% greater (-4% to 186%; P=0.07) in the non-tailored letter group than that in the no letter group. Among participants who smoked <20 cigarettes per day, the cessation rate in the non-tailored letter group was 87% greater (0% to 246%; P=0.05) than that in the no letter group. Among heavy smokers who did not quit, a 76% higher rate of positive shift in "stage of change" (intention to quit within a particular period of time) was seen compared with those who received no letter (11% to 180%; P=0.02). The increase in cost for each additional quitter in the non-tailored letter group compared with the no letter group was pound 89.
                In a large general practice, a brief non-tailored letter effectively increased cessation rates among smokers. A tailored letter was not effective in increasing cessation rates but promoted shift in movement towards cessation ("stage of change") in heavy smokers. As a pragmatic tool to encourage cessation of smoking, a mass mailing of non-tailored letters from general practices is more cost effective than computer tailored letters or no letters. There have been few community-based randomized, controlled intervention trials for cessation in high-risk smokers. In such a trial we evaluated the effects of postal smoking cessation advice in smokers with asbestos exposure and/or reduced forced expiratory volume in one second (FEV1). All men aged 30-45 yrs (n=22,392) living in 34 municipalities in western Norway were invited to a cross-sectional community survey. Information on smoking habits and occupational asbestos exposure were obtained from self-administered questionnaires and measurements of FEV1 were performed with dry-wedge bellow spirometers. Among 16,393 participants we identified a group of 2,610 smokers with previous occupational asbestos exposure and/or adjusted FEV1 in the lowest quartile. A random half (n=1,300) received a mailed personal letter from a respiratory physician with a person-specific health advice to quit smoking and a pamphlet on smoking cessation. The remaining smokers (n=1,310) acted as controls and did not receive any information. Twelve months after the intervention, information on smoking habits was re-examined using a postal questionnaire. Among the respondents (n=2,282), smoking cessation was reported altogether by 13.7% in the intervention group versus 9.9% in the control group (p<0.01). The 1 yr sustained quit rate (no smoking at all during the last year) was 5.6 versus 35% (p<0.05), respectively. Measurements of carbon monoxide in expired air (with < or = 10 parts per million) confirmed self-reported nonsmoking in samples of the two groups. In a community this simple postal smoking cessation advice from a respiratory physician based on person-specific risk factors improved the 1 yr sustained success rate by 60% in identified high-risk smokers. Public health and hospital nurses have widespread contact with smokers; an effective smoking cessation program administered by nurses has tremendous potential. This study evaluated: 1) the effectiveness of the self-help cessation program, "Time to Quit"/"Moi aussi, j'écrase" (TTQ), provided on a one-to-one basis; and 2) a smoking cessation training program for baccalaureate nursing students. Nursing students recruited 307 smokers who were randomly assigned to receive one of two interventions. Control smokers received a list of community smoking cessation resources and experimental subjects received this list plus TTQ. Smoking self-reports and cotinine levels were obtained at baseline, six weeks and nine months. More smokers receiving TTQ had reduced at six weeks post-intervention, while there were no differences in quit or reduction rates at the nine-month follow-up. Students were positive about learning the techniques and their knowledge scores were significantly higher than those of non-participating students. Using a complete factorial design, we tested three interventions for smoking cessation in routine primary care practice. The interventions tested were 1) physician counseling, 2) mailed letters and educational materials designed by the National Cancer Institute (NCI), and 3) referral to smoking cessation classes. Thirty-seven family practice physicians at three of Group Health's outpatient facilities participated. Patient participation rates were 95%, and follow-up was complete for 92% of those participating. None of the interventions had any effect on point prevalence of quitting as determined 8-9 months later by self-report. However, the combination of physician counseling and NCI materials doubled the odds of occurrence of significant antismoking behavior (quit, quit and relapse, or cut down) during the ensuing 8-9 months in those individuals receiving that combination. Referral to smoking cessation classes was strikingly ineffective in this setting. Of 369 individuals designated by study design for referral, only 14% even investigated the classes. This compares with a 10% self-referral rate for those persons not designated for referral by our study design. Our results and other recent work suggest that more intensive interventions on multiple occasions based on relapse prevention strategies hold promise for future success in smoking cessation efforts in primary care. This study demonstrated the effectiveness of a computer-delivered smoking cessation program for the worksite. 58 VA Medical Center employees were randomly assigned to a computer group (computerized nicotine fading and stop-smoking contest) or a contest-only group. In comparison with the contest-only group, the computer group had nonsignificantly higher abstinence rates across follow-up, had marginally lower CO levels at the 3- and 6-month follow-ups, and smoked cigarettes with lower nicotine levels at the 10-day and 6-month follow-ups. Randomized controlled trials of smoking interventions have not been well-documented for lung cancer screening populations. In this study, we randomly assigned 171 current smokers who were undergoing low-dose fast spiral chest CT (SCTS) for lung cancer screening to receive either standard written self-help materials or a written list of Internet resources for smoking cessation. At the 1-year follow-up, more of the subjects receiving Internet-based resources reported making a stop attempt (68% versus 48%, P=0.011). However, there were no statistically significant differences in 7-day point prevalence quit rates (5% versus 10%) or advancement in motivational readiness to stop smoking (27% versus 30%), respectively, between the groups. Clearly, more investigation is warranted into how to tailor smoking interventions for cancer screening participants. The current study evaluated the effectiveness of widely used self-help materials for quitting smoking. Five hundred and seventy smokers volunteered during a baseline survey to participate in the evaluation. After random assignment, 200 were mailed National Cancer Institute (NCI) "Quit for Good" materials, 200 the Minnesota "Quit and Win" program, and the remaining 170 were assigned to a nonintervention control condition. Results at 7-month follow-up failed to indicate treatment effects either for abstinence or for reported quit attempts. A number of smokers quit prior to the mailing of self-help materials, suggesting that a telephone prompt in itself may have been an important stimulus to cessation. Overall abstinence at follow-up was 10%. Contrary to expectation, successful participants were less likely to use a number of specific preparation strategies for quitting. The results are instructive in providing a large-scale assessment of self-help materials in a population of smokers that was not specifically seeking treatment. It has been suggested that tailoring self-help materials for specific target populations will increase their effectiveness. This study tested the value of a self-help guide tailored specifically for women with young children. These women were recruited through a media campaign that encouraged smokers to call the Cancer Information Service (CIS) for assistance in stopping smoking. Women smokers with young children (under the age of 6) who called the CIS were given telephone counseling on quitting and were mailed one of three stop smoking guides. One third of callers received Quitting Times, a guide written specifically for women with young children; one third received the American Lung Association guide, Freedom from Smoking for You and Your Family; and one third received Clearing the Air, a guide developed by the National Cancer Institute. Six months after calling the CIS, these women were contacted by telephone to assess changes in smoking behavior. Overall, 12.5% of the women reported not smoking for at least 1 week at the time of the 6-month follow-up interview. There were no significant differences between subjects in the three groups in use of the self-help guides, methods used to attempt quitting, and quitting behavior. Findings from this study do not support the hypothesis that using a tailored stop smoking guide increases the targeted audience's cessation rate or affects quitting-related behavior. However, it should be noted that the smokers who called were predominantly in the contemplation or action stages. We examined the ability of a provider-initiated, minimal-contact intervention to modify the smoking behavior of ambulatory clinic patients. Smokers at two outpatient sites were assigned to one of three groups: provider intervention only (PI); provider intervention plus self-help manual (PI/M); and usual care (control) group (C). The physician message emphasized the patient's personal susceptibility, the physician's concern, and the patient's ability to quit (self-efficacy). The nurse consultation concentrated on benefits and barriers associated with stopping, and on strategies for cessation. Telephone interviews were conducted with the 250 participants within a few days of their clinic visit and again at one and six months. Both PI and PI/M proved to be superior to usual care in motivating attempts to quit at both one-month and six-month follow-ups, and logistic regression analyses indicated that participants receiving the self-help manual in addition to the health provider message were between two and three times more likely to quit smoking during the study period than were participants in either of the other study groups. To test the efficacy of (i) computer-generated tailored letters and (ii) practitioner-delivered brief advice for smoking cessation against an assessment-only condition; and to compare both interventions directly.
                Quasi-randomized controlled trial.
                A total of 34 randomly selected general practices from a German region (participation rate 87%).
                A total of 1499 consecutive patients aged 18-70 years with daily cigarette smoking (participation rate 80%).
                The tailored letters intervention group received up to three individualized personal letters. Brief advice was delivered during routine consultation by the practitioner after an onsite training session. Both interventions were based on the Transtheoretical Model of behaviour change.
                Self-reported point prevalence and prolonged abstinence at 6-, 12-, 18- and 24-month follow-ups.
                Among participants completing the last follow-up, 6-month prolonged abstinence was 18.3% in the tailored letters intervention group, 14.8% in the brief advice intervention group and 10.5% in the assessment-only control group. Assuming those lost to follow-up to be smokers, the rates were 10.2%, 9.7% and 6.7%, respectively. Analyses including all follow-ups confirmed statistically significant effects of both interventions compared to assessment only. Using complete case analysis, the tailored letters intervention was significantly more effective than brief advice for 24-hour [odds ratio (OR) = 1.4; P = 0.047] but not for 7-day point prevalence abstinence (OR = 1.4; P = 0.068) for prolonged abstinence, or for alternative assumptions about participants lost to follow-up.
                The study demonstrated long-term efficacy of low-cost interventions for smoking cessation in general practice. The interventions are suitable to reach entire populations of general practices and smoking patients. Computer-generated letters are a promising option to overcome barriers to provide smoking cessation counselling routinely. Treating multiple health behavior risks on a population basis is one of the most promising approaches to enhancing health and reducing health care costs. Previous research demonstrated the efficacy of expert system interventions for three behaviors in a population of parents. The interventions provide individualized feedback that guides participants through the stages of change for each of their risk behaviors. This study extended that research to a more representative population of patients from primary care practice and to targeting of four rather than three behaviors.
                Stage-based expert systems were applied to reduce smoking, improve diet, decrease sun exposure, and prevent relapse from regular mammography. A randomized clinical controlled trial recruited 69.2% of primary care patients (N = 5407) at home via telephone. Three intervention contacts were delivered for each risk factor at 0, 6, and 12 months. The primary outcome measures were the percentages of at-risk patients at baseline who progressed to the action or maintenance stages at 24-month follow-up for each of the risk behaviors.
                Significant treatment effects were found for each of the four behaviors, with 25.4% of intervention patients in action or maintenance for smoking, 28.8% for diet, and 23.4% for sun exposure. The treatment group had less relapse from regular mammography than the control group (6% vs. 10%).
                Proactive, home-based, and stage-matched expert systems can produce relatively high population impacts on multiple behavior risks for cancer and other chronic diseases. Although tailored interventions consisting of only a few pages of information lead to more quitting than no intervention in the short term, the long-term efficacy of a single tailored intervention still has to be proven. In the present study smokers were reactively recruited and randomly allocated to one of four intervention conditions: (1) outcome information, (2) self-efficacy enhancing information, (3) both sorts of information or (4) no information. Smokers in the three experimental groups received computer-generated tailored feedback containing the condition-specific information, by mail. The results from the 14 months follow-up can be summarized as follows. Compared to the no information condition, all three experimental conditions led to significantly more smokers who had engaged in 24-h quit attempts. However, no experimental condition led to more 7-day quitting than the no information condition. With regard to continuous abstinence, the experimental condition offering a combination of outcome information and self-efficacy enhancing information had a significant effect, compared to the no information condition. It is concluded that a minimal six-page tailored intervention can be beneficial in supporting smokers to quit smoking, even after 14 months. This article evaluates the effects and use of adjuncts to a televised smoking cessation program, based on the American Lung Association's "Freedom From Smoking in 20 Days." Subjects were randomized to maintenance and control conditions. The maintenance condition received newsletters with information and support addressing different stages in the cessation process and information about a telephone hotline. The maintenance condition did not increase cessation at any wave of interviewing, assessed by multiple point or point prevalence of abstinence. Those abstinent at 6 months and those who had made an attempt to stop smoking by that time were more likely to have used the newsletters and were more likely to have used the sections relevant to their cessation stage. Rates of use of the telephone hotline were low. The newsletters appear to be useful to smokers who are predisposed to use written materials. Self-help materials computer-tailored to the specific needs of smokers have shown promise as a high-reach, low-cost intervention for smoking cessation. Adding tailored cessation materials to telephone-based cessation counseling may be a way of generating greater efficacy in promoting and maintaining cessation. The objective of this study is to assess the efficacy of adding different types of behavioral smoking cessation materials to brief telephone-based cessation counseling.A total of 1,978 smokers calling the National Cancer Institute's (NCI's) Cancer Information Service (CIS) for help in quitting smoking initially received brief cognitive-behavioral cessation counseling from a CIS information specialist. Following a baseline interview administered by the information specialist, subjects were randomly assigned to one of four conditions, each delivered by U.S. mail: a single, untailored smoking cessation guide (SU); a single, tailored smoking cessation guide (ST); a series of four (multiple) printed materials tailored only to baseline data (MT); and a series of four (multiple) printed materials tailored to baseline as well as retailored using 5-month interim progress data (MRT). The primary outcome measure was 7-day point prevalence abstinence rates assessed using a computer-assisted telephone interview (CATI) at 12-month follow-up.At 12-month follow-up, using intent-to-treat, imputed, and per-protocol analyses, no differences were found among the four experimental conditions (linear trend), or when the ST, MT, and MRT groups were compared with the control (SU) group. Participants in the two multiple message group conditions combined (MT + MRT), however, had significantly higher abstinence rates than participants in the two single message group conditions combined (SU + ST). Moreover, among subjects who reported quitting at the 5-month follow-up, participants receiving the MRT materials reported higher abstinence rates at 12 months than the other three groups combined (SU + ST + MT). The results of this study support the effectiveness, over and above a single telecounseling interaction, of multiple tailored print material contacts on cessation. These effects, however may be due to tailoring, or the longitudinal nature of the two multiple tailored conditions, or both. The strongest evidence for tailoring occurred in the MRT condition for relapse prevention, suggesting that print materials tailored to interim progress may be especially effective in this context. The qualities of specific psychosocial and communication elements in tailored materials should receive attention in future research. To evaluate the effectiveness of individually tailored smoking cessation advice letters as an adjunct to telephone counselling and generic self-help materials.
                Randomized controlled trial.
                The UK Quitline.
                A total of 1508 current smokers and recent ex-smokers.
                The control group received usual care (telephone counselling and an information pack sent through the post). The intervention group received in addition a computer-generated individually tailored advice letter.
                All outcomes were assessed at 6-month follow-up. The primary outcome measure was self-reported prolonged abstinence for at least 3 months. Secondary outcomes were self-reported prolonged abstinence for at least 1 month and 7-day and 24-hour point-prevalence abstinence.
                For the sample as a whole, quit rates did not differ significantly between the two conditions. However, among the majority (n = 1164) who were smokers at baseline, quit rates were consistently higher in the intervention group: prolonged abstinence for 3 months, 12.2% versus 9.0% [odds ratio (OR) = 1.40, 95% confidence interval (CI) = 0.96-2.04, P = 0.080); prolonged abstinence for 1 month, 16.4% versus 11.3% (OR = 1.53, 95% CI = 1.09-2.15, P = 0.013); 7-day point-prevalence abstinence, 18.9% versus 12.7% (OR = 1.59, 95% CI = 1.15-2.19, P = 0.004); 24-hour point-prevalence abstinence, 20.9% versus 15.4% (OR = 1.45, 95% CI = 1.07-1.96, P = 0.015).
                The results for the smokers are encouraging in showing a small but useful effect of the tailored letter on quit rate. Versions of the tailoring program could be used on the web and in general practices, pharmacies and primary care trusts. The objective was to assess the effectiveness of a directly mailed smoking cessation intervention to discharged hospital patients.
                A randomized controlled trial was used. In the 2 weeks after discharge, smokers in the intervention group were sent by mail a personally addressed letter from their medical consultant urging them to quit plus a self-help quitting manual, and smokers in the control group received usual care. Patients were surveyed about their smoking status at 6 and 12 months after discharge. A total of 1858 discharged patients responded to both questionnaires. The main outcome measures were self-reported smoking in past week at 6 and 12 months after discharge. Quitters at 12 months were biochemically tested for evidence of smoking.
                The results failed to show that smoking cessation advice directly mailed to a broad cross-section of discharged hospital patients who smoke led to smoking cessation. However, the intervention increased cessation among smokers with medical conditions for which quitting is highly relevant. In general, patients who were more likely to quit were older, had entered the hospital as an emergency case, and had a medical diagnosis for which quitting is highly relevant.
                This study suggests that hospital patients who smoke and are also diagnosed with conditions which call for quitting are more likely to quit if they receive from their consultant a personalized letter advising them to quit and a self-help manual.
                Copyright 1999 American Health Foundation and Academic Press. Sixty-six physicians were randomized to three groups to conduct a 1-month campaign to help their patients stop smoking. The workshop group received free patient education materials and a 6-hour training workshop. The materials group received free patient education materials, and the no-assistance group received nothing. A telephone interview was completed with 89% of the 6767 eligible adult patients seen during the month of the campaign. The brief training program and patient education materials marginally increased the smoking intervention activities of volunteer physicians in private practice. Both workshop and materials physicians asked 54% of their smoking patients to stop; no-assistance physicians asked 40%. One year later, 36% of patients who had not even been asked by their doctors if they smoked reported that they had tried to stop smoking. If the physician had asked the patient if he or she smoked, the probability of a quit attempt was 47%. Patients who had been asked if they smoked were more likely to claim to have stopped (13%) than patients who had not been asked (9%). However, the proportion of patients claiming continued abstinence (range, 12% to 14%) was not related to the group of the physician. 1,218 smokers able to quit smoking for 48 hr were randomly assigned to one of 12 cells in a 4 x 3 fully crossed factorial experiment. A pharmacologic factor contained four levels: nicotine polacrilex (gum) delivered ad lib or on a fixed regimen, placebo gum, and no gum. A self-guided behavioral treatment factor contained three levels: self-selected relapse prevention modules, randomly administered modules, and no modules. Those receiving nicotine gum were more likely to be abstinent at the 2- and 6-month follow-ups. The fixed regimen accounted for most of the effect for gum. There was no effect for the relapse prevention module factor. Men and women showed a differential treatment response. Men who received nicotine gum were more likely to be abstinent at each follow-up (2, 6, and 12 months). No treatment was significantly better among women. We conclude that research on different gum chewing regimens is warranted and that further examination of possible gender differences in response to replacement therapy is needed. To assess the effectiveness of a new computer-generated tailored advice programme designed to be used by smokers and recent quitters having problems staying stopped.

                A total of 1058 smokers or recent quitters recruited from callers to the Quitline.
                Smoking status and sustained abstinence at 12-month follow-up, plus extent of participation in the intervention.
                Using a conservative analysis (missing data coded as a treatment failure), 6-month sustained abstinence was reported by significantly more participants in the computer-generated tailored advice (20%) than the standard printed materials condition (12%) at 12-month follow-up OR 1.82 (1.31-2.55)). Group differences in point prevalence abstinence (28% intervention, 25% control) were not significant. Among participants in the tailored advice condition, 6-month sustained abstinence was associated with the number of advice letters received.
                The provision of a series of tailored, computer-generated advice letters resulted in greater rates of sustained cessation than for controls. A dose-response relationship was found, with increased compliance with the intervention associated with improved cessation outcomes. The programme appears to have much of its effect by preventing relapse. A 2-year self-help manual smoking cessation intervention was conducted among a panel of middle-aged Finnish men (n = 265) who were recruited proactively in a longitudinal cardiovascular risk factor surveillance study.
                Intervention utilized the stages of change concept of the transtheoretical model. The stages were assessed in the treatment condition at baseline of the cessation study and after that by mail every sixth month. Assessments were followed by an immediate mailing of a stage-based self-help manual matching the stage of change at that time. A usual care group was assessed annually but received no treatment.
                A significant time x intervention effect (P < 0.05) and time x baseline stage effect (P < 0.001) on quit rates were observed in the panel data over the 2-year period. An analysis of changes in the stages of change also revealed an accelerated cessation process in the treatment condition.
                We conclude that mailed stage-matched self-help smoking cessation manuals were able to accelerate the smoking cessation process but manuals alone may not constitute a sufficient long-term intervention. The effects of differential exposure to intervention, subject characteristics, measurement reactivity, and secular trends are discussed as potential confounds. To assess the effectiveness of a program of computer-generated tailored advice for callers to a telephone helpline, and to assess whether it enhanced a series of callback telephone counselling sessions in aiding smoking cessation.
                Randomized controlled trial comparing: (1) untailored self-help materials; (2) computer-generated tailored advice only, and (3) computer-generated tailored advice plus callback telephone counselling. Assessment surveys were conducted at baseline, 3, 6 and 12 months.

                A total of 1578 smokers who called the Quitline service and agreed to participate.
                Smoking status at follow-up; duration of cessation, if quit; use of nicotine replacement therapy; and extent of participation in the callback service.
                At the 3-month follow-up, significantly more (chi2(2) = 16.9; P < 0.001) participants in the computer-generated tailored advice plus telephone counselling condition were not smoking (21%) than in either the computer-generated advice only (12%) or the control condition (12%). Proportions reporting not smoking at the 12-month follow-up were 26%, 23% and 22%, respectively (NS) for point prevalence, and for 9 months sustained abstinence; 8.2, 6.0, and 5.0 (NS). In the telephone counselling group, those receiving callbacks were more likely than those who did not to have sustained abstinence at 12 months (10.2 compared with 4.0, P < 0.05). Logistic regression on 3-month data showed significant independent effects on cessation of telephone counselling and use of NRT, but not of computer-generated tailored advice.
                Computer-generated tailored advice did not enhance telephone counselling, nor have any independent effect on cessation. This may be due to poor timing of the computer-generated tailored advice and poor integration of the two modes of advice. Self-Instructional behavior-change programs for reducing risks to health are potentially widely available, acceptable and cost-effective. This paper reports outcomes of a smoking cessation program administered by mail. Two hundred and eight smokers were allocated systematically to a quit kit control condition (n = 40), to a standard correspondence course (n = 86) and to a personalized correspondence course prepared with the aid of a microcomputer (n = 82). There were significantly higher rates of abstinence after the course for correspondence course participants compared to controls, but these differences did not persist at three-month and nine-month follow-ups. There were no differences between the personalized and standard courses on abstinence rates, number of cigarettes smoked per day, or return of feedback forms on each lesson. There were associations between self-efficacy strength and reduced rates of smoking, and active participation in the course was associated with lower smoking rates. One of the key goals of health promotion strategies in the UK and other developed countries is to reduce the prevalence of cigarette consumption. While overall smoking rates in the UK have fallen over the last few decades, they have barely fallen for the least advantaged adults (Department of Health, 1998a). There is a need for interventions that are suitable for lower socio-economic status (SES) smokers that have undergone rigorous evaluation. This study describes a randomized controlled trial of cognitive behaviour therapy (CBT) with smokers from a deprived area of London. At 6 months follow-up, 21 (17.2%) of 122 participants receiving therapy were abstinent and 14 (11.5%) had reduced cigarette consumption by at least 25% of pre-treatment level. Six (5.6%) of 107 participants in the control group were abstinent and none had reduced consumption. These results suggest that this self-help CBT intervention has the potential to reduce the prevalence of smoking among lower SES smokers. To examine the relative effectiveness of three different presentations of a smoking cessation program on the smoking behavior of adults with cardiovascular health problems.
                A 2 x 2 x 2 x 4 experimental design with stratification by sex, smoking history, and a cardiovascular event, and randomization to Individual, Group, Written, or No Intervention groups.
                Six community hospital classrooms.
                255 nonhospitalized adults. THEORETIC FRAMEWORK: Interaction Model of Client Health Behavior.
                Study Intake: Professional referral form, demographic questionnaire, smoking habits questionnaire, health history, perceived threat survey, perceived health status. Follow up: smoking cessation and health questionnaire, saliva thiocyanate testing.
                At 12-month follow-up, a nurse-client interaction was more effective than written self-help materials; however, smoking cessation rates were highest in the No Intervention control group, possibly related to having had coronary artery bypass graft surgery. Variables positively related to quitting were being male and married and having a higher income. With baseline factors considered, a quitter was most likely to be male and less than 48 years of age, have a high degree of perceived threat relative to medical diagnosis, and be in the individual intervention group. Only partial support for the study hypotheses was found. Pharmacological interventions for smoking cessation are typically evaluated using volunteer samples (efficacy trials) but should also be evaluated in population-based trials (effectiveness trials). Nicotine replacement therapy (NRT) alone and in combination with behavioral interventions was evaluated on a population of smokers from a New England Veterans Affairs Medical Center. Telephone interviews were completed with 3,239 smokers, and 2,054 agreed to participate (64%). Participants were randomly assigned to one of four conditions: stage-matched manuals (MAN); NRT plus manuals (NRT + MAN); expert system plus NRT and manuals (EXP + NRT + MAN); and automated counseling plus NRT, manuals, and expert system (TEL + EXP + NRT + MAN). Assessments were completed at baseline, 10, 20, and 30 months. The point prevalence cessation rates at final follow-up (30 months) were MAN, 20.3%; NRT + MAN, 19.3%; EXP + NRT + MAN, 17.6%; and TEL + EXP + NRT + MAN, 19.9%. Stage-matched manuals provided cessation rates comparable with previous studies. The addition of NRT, expert system interventions, and automated telephone counseling failed to produce a further increase in intervention effectiveness.
                ((c) 2006 APA, all rights reserved). The authors develop and test a culturally sensitive, low-intensity smoking cessation intervention for low-socioeconomic African Americans. African American adult smokers were randomly assigned to receive either a multicomponent smoking cessation intervention comprising a printed guide, a video, and a telephone booster call or health education materials not directly addressing tobacco use. The results of the study were mixed. Although no significant effects were observed for the entire treatment cohort, the results of post hoc analyses suggest that culturally sensitive self-help smoking cessation materials plus a single phone contact can produce short-term cessation rates similar to those reported for majority populations. This conclusion should be tempered by the low completion rate for the booster call and several design limitations of the study. This prospective randomized study examined the impact of three tailored intervention approaches to increase quitting rates among African-American smokers who were clients of a community health center that serves primarily low-income and indigent persons. Smokers were randomized to one of three groups: (1) health care provider prompting intervention alone, (2) health care provider prompting intervention with tailored print communications, and (3) health care provider prompting intervention with tailored print communications and tailored telephone counseling. Among the 160 smokers who completed the study, 35 (21.8%) had quit smoking at follow-up. Smokers who received the provider prompting intervention with tailored print materials were more likely to report having quit than smokers who received the provider intervention alone (32.7% vs. 13.2%, p < 0.05). Smokers who received all three intervention components were not more likely to report having quit at follow-up than those who only received the provider intervention (19.2% vs. 13.2%). Smokers who at baseline were less educated, smoked less than half a pack of cigarettes per day, had a stronger desire to quit, felt more efficacious, and had thought about quitting were more likely to report having quit at follow-up. These results provide support for continued refinement of tailored communications to aid smoking cessation among African-American smokers. This study evaluated the effects of written feedback adapted to a self-help mail intervention. The efficacy of the standard mail intervention treatment was 37% at the end of treatment, 22% at the 3-month follow-up, 19% at the 6-month follow-up, and 13% at the 12-month follow-up. In contrast, the standard mail program combined with personalized written feedback resulted in an efficacy of 51% at the end of treatment, 37% at the 3-month follow-up, 32% at the 6-month follow-up, and 27% at the 12-month follow-up. Both groups were significantly different from the control group at the end of treatment (0%), at the 3-month follow-up (1%), and at the 6-month follow-up (1%). There was a significant reduction in the number of cigarettes smoked daily among continuing smokers under both experimental conditions. The authors conclude that written feedback substantially increases abstinence rates when it is applied following similar guidelines to those used in clinical settings. Reaching nonvolunteer female smokers with effective smoking cessation programs is a critical public health challenge. Smokers (N = 2,786) among 15,004 female members of a health maintenance organization who completed a routine needs assessment were invited into the "UCLA Preventive Health Behavior Study," consisting of five telephone interviews over 2 years assessing health practices. Participants (N = 1,396) were randomized into experimental or control conditions of an unsolicited, mailed, self-help smoking cessation program. Subjects were not alerted to the link between the program and the health study. Smoking status was assessed at 1, 6, 12, and 18 months. Across all subjects, point prevalence at 18 months was 18.62, and continuous abstinence was 2.71%. No difference was found between treatment and control groups regarding smoking status or readiness to stop smoking--raising questions about the value of mailing cessation materials to nonvolunteers. Quit rates increased over the 18-month follow-up; those still smoking at 18 months reported increased readiness to quit. Predictors at each follow-up point were examined multivariately. This study reports the outcome of a randomized controlled trial testing a computer-tailored smoking cessation intervention based on the transtheoretical model in a general population setting in Germany. Participants of the smoking intervention study were recruited from an existing general population health examination survey in a university hospital. The sample consisted of 611 current and former smokers at baseline, and of 485 participants in the core group of baseline daily cigarette smokers. Follow-ups were conducted 6, 12, 18, and 24 months after baseline. The intervention was designed for both current and former smokers, involved up to three individualized feedback letters, and was created using expert-system technology. Based on 7-day point-prevalence abstinence and 6-month prolonged abstinence as the outcome measures, the study identified no significant differences between the intervention and control groups. Modeling the full longitudinal data in generalized estimation equation analyses, using different nonresponse procedures, and adjusting for covariates did not alter the results. We conclude that the computer-tailored transtheoretical model-based smoking cessation intervention, as delivered in this study and in this special setting, was ineffective. Smokers aged 18 to 65 years (N = 1,044) who were able to quit for 24 hr were randomized using a 2 x 2 factorial design to compare nicotine gum to no gum use and self-help materials to no use of materials. All participants were offered a $100 incentive to quit and stay quit for 6 months. Six-month abstinence was 27% in the gum groups, compared with 19% in the no-gum group (p = .002). Compared with the no-gum group, relapse occurred at a significantly lower rate in the gum group for the entire 12 months of follow-up (odds of relapse in the gum group was 0.72, 95% confidence interval, 0.62 to 0.83). There was no significant main effect for the self-help materials, no interaction between gum and materials, and no evidence that the effectiveness of gum differed between the sexes or between heavy and light smokers. Nicotine gum is an effective adjunct to minimal-contact smoking cessation materials plus monetary incentive in a population-based sample of smokers. Three stage-based expert system interventions for smoking, high-fat diet, and unsafe sun exposure were evaluated in a sample of 2,460 parents of teenagers. Eighty-four percent of the eligible parents were enrolled in a 2-arm randomized control trial, with the treatment group receiving individualized feedback reports for each of their relevant behaviors at 0, 6, and 12 months as well as a multiple behavior manual. At 24 months, the expert system outperformed the comparison condition across all 3 risk behaviors, resulting in 22% of the participants in action or maintenance for smoking (vs. 16% for the comparison condition), 34% for diet (vs. 26%), and 30% for sun exposure (vs. 22%). Proactive, home-based, and stage-matched expert systems can produce significant multiple behavior changes in at-risk populations where the majority of participants are not prepared to change.
                ((c) 2004 APA, all rights reserved) nan One thousand two hundred thirty seven smokers responding to lung association announcements in five geographic areas were randomly assigned to one of four groups and mailed American Lung Association materials: 1) leaflets (L); 2) leaflets plus maintenance manual (L + M); 3) cessation manual (C); and 4) cessation and maintenance manuals (C + M). Five telephone interviews over one year achieved a 95 per cent follow-up completion rate. Nonrespondents as well as exclusive cigar and pipe users were classified as smokers. Twenty per cent quit initially, with 5 per cent continually abstinent in (C + M) at 12 months vs 2 per cent in (L) (p less than .05). Nonsmoking prevalence rates (no tobacco smoking in the past month), on the other hand, gradually increased after six months; at 12 months those with the maintenance component, (L + M) and (C + M), had higher rates (18 per cent) than (L) (12 per cent) or (C) (15 per cent). Leaflets and manual alone were least cost effective. Rising nonsmoking prevalence rates observed in all groups suggest that successful attempts to quit increased over time and that a contributing factor might have been the follow-up method. Although achieving lower quit rates than methods requiring attendance at a course, the self-help intervention has the advantages of greater availability, flexibility, and in some instances lower cost. This article presents results from an experimental study designed to evaluate the effects of two features of self-help smoking cessation booklets, format (i.e., day-by-day plan for quitting versus a less structured menu format) and quitting instructions (i.e., "cold turkey" versus gradual reduction) on smoking cessation. Four separate self-help booklets were developed for comparison in this study. Each varied on a combination of the two study factors, but were similar in content, length, style, and readability. The four booklets provided similar advice on how to quit smoking, emphasizing behavioral self-management principles. In addition to the experimental booklets, a fifth control booklet provided general information about smoking and its adverse effects, but no specific advice on quitting. Study subjects included 1,534 adult cigarette smokers who called a stop smoking hotline in Buffalo, New York seeking information on how to quit. Subjects were followed up by phone one month and six months after enrollment to assess changes in smoking behavior. Overall, 18% of subjects reported of being off cigarettes for at least one week at the time of the six month follow-up interview. The format of the booklet and quitting instructions had no effect on smoking cessation rates. In addition, the four booklets emphasizing behavioral self-management skills were no more effective than the control booklet (6 month non-smoking prevalence rate: 17% versus 19%). It is recommended that future self-help quit smoking booklets include information aimed at motivating cessation and focus less attention on teaching strategies for quitting. Self-help methods are preferred by smokers over clinic-based treatments providing more traditional services. Unfortunately, these more popular methods have not been extremely successful in getting smokers to quit. The poor success rates may be partially related to the lack of structure inherent in these treatment approaches. The present study examined a self-help program delivered to smokers via a written manual and limited duration phone calls--the latter to add structure to the treatment procedures. The results, a 23% abstinent rate, indicate that this approach has some promise for treating chronic smokers. To examine the options for use, efficiency, and effectiveness for structuring a population-based telephone smoking-cessation service.
                Callers (n=632) to a 1-800 number were randomized in a 2 (50-minute counseling with 2/6 calls) x 2 (pamphlet/booklet) design with print only control.
                Six-month use of the service was 0.6% of adult smokers. Service promotion cost 31.02 dollars/person. Telephone counseling resulted in higher continued abstinence (5%) than did print only (1%), P<.05. Amount of print and calls did not increase cessation. Six calls resulted in lower completion rates than 2 (22% vs 56%, P<.05).
                For planning, consider 1% use, low-cost promotion, pamphlet, 50-minute initial counseling plus 2 follow-ups, and minimize call-attempts. The purpose of the present study was to determine the effectiveness of a self-help smoking cessation manual for patients with pulmonary disease. All patients were advised to quit smoking by a respiratory specialist. Thirty-five patients were then provided with a manual detailing techniques for quitting; the remaining 40 patients served as a control and were given no additional information or instruction following advice. The cessation rate in the treatment group was 16.7%; and in the control group, 25.6%. This difference was not statistically significant. Approximately half of the patients who received the manual used it, and only 12.5% of the users found it helpful. It was concluded that providing patients with the specific instructions on quitting smoking as presented in the manual did not appear to be useful. The present study assessed the incremental effectiveness of behavioral self-help materials specifically written to accompany nicotine gum. Subjects (187 women and 117 men) were randomly assigned either behavioral self-help booklets or a factual information pamphlet. All subjects received prescriptions for Nicorette from study physicians. Contrary to prediction, subjects provided self-help booklets fared no better than did subjects provided comparison pamphlets. Overall abstinence levels were encouraging, however. Nicotine gum users were far more likely than nonusers to maintain abstinence through 6-month follow-up. Perhaps self-help materials could be improved by condensing and simplifying content and by adopting a more attractive multicolored pictorial format. nan nan Physician-delivered advice to stop smoking is effective, but time demands often reduce the number of smokers who receive assistance. We evaluated three nurse-assisted interventions designed to minimize physician burden and increase counseling in primary care settings.
                Randomized controlled trial with a 12-month follow-up.
                Internal medicine and family practice offices in a health maintenance organization.
                Smokers (n = 3161) who were patients of participating physicians or other medical care providers (n = 60).
                Medical care providers delivered a 30-second stop-smoking prompt to 2707 smokers and referred them to an on-site nurse smoking counselor. The nurse randomly provided a two-page pamphlet (advice control) or one of three nurse-assisted interventions: 1) self-quit training; 2) referral to a group cessation program; or 3) a combination of self-quit training and referral. Each nurse-delivered intervention included a 10-minute video, written materials, and a follow-up phone call.
                Physicians delivered brief advice to 86% of identified smokers during the 1-year program. The proportion of participants reporting abstinence after both 3 and 12 months of follow-up nearly doubled (P = 0.01) for the nurse-assisted self-quit (7.1%), group-referral (7.6%), and combination (6.9%) interventions, compared to brief physician advice alone (3.9%) (P < 0.05). Saliva cotinine tests confirmed these effects (P < 0.004), although quit rates were lower (3.4%, 4.7%, 4.3%, and 2.3%, respectively) because roughly one half of quitters chose not to provide a saliva sample and were counted as smokers.
                Involving nurses in counseling smokers reduces physician burden, makes counseling more likely, and significantly increases cessation rates compared with brief physician advice alone.
Standard self-help materials may increase quit rates compared to no intervention, but the effect is likely to be small. We failed to find evidence that they have an additional benefit when used alongside other interventions such as advice from a healthcare professional, or nicotine replacement therapy. There is evidence that materials that are tailored for individual smokers are more effective than untailored materials, although the absolute size of effect is still small.
