nan Two treatments for bulimia nervosa have emerged as having established efficacy: cognitive-behavioral therapy and antidepressant medication. This study sought to address 1) how the efficacy of a psychodynamically oriented supportive psychotherapy compared to that of cognitive-behavioral therapy; 2) whether a two-stage medication intervention, in which a second antidepressant (fluoxetine) was employed if the first (desipramine) was either ineffective or poorly tolerated, added to the benefit of psychological treatment; and 3) if the combination of medication and psychological treatment was superior to a course of medication alone.
                A total of 120 women with bulimia nervosa participated in a randomized, placebo-controlled trial.
                Cognitive-behavioral therapy was superior to supportive psychotherapy in reducing behavioral symptoms of bulimia nervosa (binge eating and vomiting). Patients receiving medication in combination with psychological treatment experienced greater improvement in binge eating and depression than did patients receiving placebo and psychological treatment. In addition, cognitive-behavioral therapy plus medication was superior to medication alone, but supportive psychotherapy plus medication was not.
                At present, cognitive-behavioral therapy is the psychological treatment of choice for bulimia nervosa. A two-stage medication intervention using fluoxetine adds modestly to the benefit of psychological treatment. This study was designed to assess the additive effects of major components of cognitive-behavioral treatment for bulimia nervosa. Seventy-seven female patients with bulimia nervosa were allocated at random to one of four conditions: wait-list control, self-monitoring of caloric intake and purging behaviors, cognitive-behavioral treatment, and cognitive-behavioral treatment combined with response prevention of vomiting. In the treatment conditions, participants were seen individually for fourteen 1-hr sessions over a 4-month period. All the treatment groups showed significant improvement, whereas the wait-list control group did not. Cognitive-behavioral treatment was, however, the most successful in reducing purging and in promoting positive psychological changes. Fifty-six percent of participants in this condition ceased binge eating and purging by the end of treatment, and the frequency of purging declined by 77.2% during the same period. Of the three treatment conditions, only cognitive-behavioral treatment was superior to the wait-list control. At the 6-month follow-up, 59% of the cognitive-behavioral group were abstinent, and purging had declined by 80%. Cognitive-behavioral treatment was significantly superior to the other treatment groups at this time. Thus, the addition of response prevention of vomiting did not enhance the efficacy of cognitive-behavioral treatment, and the evidence suggests that it may have had a deleterious effect. The purpose of this study was to identify predictors of short-term treatment outcome for individuals with binge eating disorder (BED).
                Fifty women who met DSM-IV criteria for BED were enrolled in a manual-based group cognitive-behavioral therapy that consisted of fourteen 1-hr sessions over an 8-week period. Baseline measures included the frequency of self-reported binge eating from the Eating Behaviors-IV (EB-IV), severity of binge eating and dietary restraint using the Binge Eating Scale (BES) and Three-Factor Eating Questionnaire (TFEQ), depressive symptoms as assessed by the Beck Depression Inventory (BDI) and the Hamilton Depression Rating Scale (HDRS), and self-esteem as measured by the Rosenberg Self-Esteem Questionnaire (RSEQ).
                Logistic regression analyses indicated that the baseline frequency of self-reported episodes of binge eating that were objectively large predicted the likelihood of such episodes at the end of treatment. No variables predicted the likelihood of binge eating episodes that were objectively and subjectively large at the conclusion of treatment.
                This study indicates that the frequency of binge eating episodes at baseline is predictive of outcome status at the end of treatment, suggesting that meaningful prognostic factors in BED are identifiable.
                Copyright 2000 by John Wiley & Sons, Inc. This study tested the initial effects of cognitive-behavioral therapy for binge eating in Ss who do not purge. Forty-four female binge eaters were randomized to either cognitive-behavioral treatment (CB) or a waiting-list (WL) control. Treatment was administered in small groups that met for 10 weekly sessions. At posttreatment a significant difference was found, with 79% of CB Ss reporting abstinence from binge eating and a 94% decrease in binge eating compared with a nonsignificant reduction (9%) in binge eating and zero abstinence rate in WL Ss. Following the posttest assessment, WL Ss were treated and evidenced an 85% reduction in binge episodes and a 73% abstinence rate. Binge eating significantly increased at 10-week follow-up for initially treated Ss; however, the frequency remained significantly improved compared with baseline levels. nan The present study investigated the efficacy of self-help based on cognitive behaviour therapy in combination with Internet support in the treatment of bulimia nervosa and binge eating disorder. After confirming the diagnosis with an in-person interview, 73 patients were randomly allocated to treatment or a waiting list control group. Treated individuals showed marked improvement after 12 weeks of self-help compared to the control group on both primary and secondary outcome measures. Intent-to-treat analyses revealed that 37% (46% among completers) had no binge eating or purging at the end of the treatment and a considerable number of patients achieved clinically significant improvement on most of the other measures as well. The results were maintained at the 6-month follow-up, and provide evidence to support the continued use and development of self-help programmes. Cognitive behavior therapy was applied to 8 inpatients with bulimia (DSM-III). Improvement of bulimia was superior when compared to 6 bulimics treated with nonspecific psychotherapy. Social maladjustment was linked to the maintenance of bulimia. The effectiveness of cognitive behavior therapy seemed to be impaired by co-morbidity and dysphoric mood. Therefore a more structured externally controlled behavioral hospital treatment program is recommended. In an effort to elucidate the role of cognitive factors in the maintenance of bulimia nervosa, the efficacy of two psychological treatments was examined in a randomised control trial: cognitive behaviour therapy in the absence of explicit exposure instructions was compared with exposure and response prevention treatment in the absence of cognitive restructuring procedures. In the short term both treatments were successful at effecting substantial improvement in both the specific and the non-specific psychopathology of the disorder. However, at a one year follow up, whilst improvements were well maintained for those who had received the cognitive-behavioural treatment, virtually all of those who had responded to the purely behavioural treatment had relapsed. This provides some support for the cognitive model of the maintenance of bulimia nervosa. Nevertheless, the two treatment groups could not be distinguished on post-treatment measures of cognitive disturbance and neither was it the case that residual levels of cognitive disturbance, as assessed, predicted relapse. This may suggest that the level at which the necessary cognitive change takes place may not be accessible by conventional assessment procedures. In a comparison of nutritional management (NM) and stress management (SM) for treatment of bulimia nervosa, 55 female patients were randomly assigned to either treatment. Therapy consisted of 15 sessions in a group over three months, by the end of which, patients under both treatment conditions showed a significant reduction in the frequency of binge eating and vomiting and a significant improvement in various psychopathological features such as body dissatisfaction and depression. All improvements were maintained over 12-month follow-up NM produced a more rapid improvement in general eating behaviour, a faster reduction in binge frequency and a higher abstinence rate from binge eating. SM led to greater positive changes in certain psychopathological features such as feelings of ineffectiveness, interpersonal distrust and anxiety. NM should be regarded as a necessary first intervention in all bulimic patients. Further psychological therapy, such as SM, is indicated as well for some patients, depending on their specific psychological difficulties. Little is known about general practice management of patients with eating disorders.
                To compare the effectiveness of a general practice-based, self-help approach to the treatment of bulimia nervosa with that of specialist outpatient treatment.
                A prospective, parallel group, randomised controlled trial.
                General practices and specialist eating disorder clinics in London.
                Patients were recruited from general practitioner (GP) referrals to specialist eating disorder clinics. Thirty-four patients were randomised to receive the self-help intervention in general practice and thirty-four were randomised to the clinic intervention. Patients randomised to the self-help arm of the trial worked through a manual based on cognitive behaviour principles, while keeping in contact with their GPs. Those randomised to receive specialist treatment were managed in the specialist clinic to which they had been referred. The main outcome measure was the Bulimic Investigatory Test Edinburgh score, assessed at baseline and at six and nine months. Secondary measures were eating pathology, depression, and social adjustment.
                A total of 74% and 80% of patients were followed up at six and nine months respectively. An intention-to-treat analysis revealed that, while bulimic symptoms declined in both groups over time, there was no significant difference in outcome between the two groups.
                The findings lend support to the idea that patients with bulimia nervosa can be treated in general practice and that this approach warrants further investigation. nan This study examined whether involving the spouse in group cognitive behavioral therapy (CBT) for binge eating disorder (BED) enhances treatment outcome relative to standard group CBT.
                Ninety-four overweight women with BED were randomly assigned to either (1) standard group CBT, (2) group CBT with spouse involvement, or (3) a wait-list control group. Eating and general psychopathology assessments were completed at baseline, after treatment, and at 6-month follow-up.
                Although both CBT groups fared significantly better than the wait-list control group on measures of binge eating, weight, eating psychopathology, and general psychopathology, CBT with spouse involvement did not result in any additional benefit over and above standard CBT.
                These results are in contrast to the success of spouse involvement in the treatment of several other physical and psychological disorders. Possible reasons for this disparity, and suggestions for improving spouse involvement in BED treatment, are discussed.
                Copyright 2003 by Wiley Periodicals, Inc. The objective of this study was to test a guided imagery therapy designed to enhance self-comforting in bulimia nervosa.
                A randomized controlled trial compared 6 weeks of individual guided imagery therapy with a control group. Fifty participants who met DSM-III-R criteria for bulimia nervosa completed the study. Measures of eating disorder symptoms, psychological functioning and the experience of guided imagery therapy were administered.
                The guided imagery treatment had substantial effects on the reduction of bingeing and purging episodes; the imagery group had a mean reduction of binges of 74% and of vomiting of 73%. The imagery treatment also demonstrated improvement on measures of attitudes concerning eating, dieting and body weight in comparison to the control group. In addition, the guided imagery demonstrated improvement on psychological measures of aloneness and the ability for self-comforting.
                Evidence from this study suggests that guided imagery was an effective treatment for bulimia nervosa, at least in the short-term. The authors compared the effectiveness of 4 months (18 sessions) of cognitive-behavioral and supportive-expressive therapy for bulimia.
                Sixty patients obtained from clinical referrals to an eating disorders program who met modified DSM-III-R criteria for bulimia nervosa were randomly assigned to the two conditions. Treatments were delivered in an individual format, on an outpatient basis, by experienced therapists using treatment manuals. The primary outcome measures were self-induced vomiting, binge eating, and attitudes toward body weight and shape, which were assessed by self-report and structured interview.
                Fifty patients completed treatment, 25 in each condition. Both treatments led to significant improvements in specific eating disorder symptoms and in psychosocial disturbances. Supportive-expressive therapy was just as effective as cognitive-behavioral therapy in reducing binge eating. Where treatment differences were found, they favored cognitive-behavioral therapy. Cognitive-behavioral therapy was marginally superior in reducing the frequency of self-induced vomiting; 36% of the patients who received cognitive-behavioral therapy and 12% of those who received supportive-expressive therapy abstained from vomiting in the last month of treatment. Cognitive-behavioral therapy was significantly more effective in ameloriating disturbed attitudes toward eating and weight, depression, poor self-esteem, general psychological distress, and certain personality traits.
                These results moderately favor cognitive-behavioral therapy over supportive-expressive therapy for bulimia nervosa, but follow-up is required to determine the durability of outcome with both modalities. The findings must be interpreted with caution since the selected clinical sample in this study may not represent the bulimia nervosa population. The effects of dialectical behavior therapy adapted for the treatment of binge/purge behaviors were examined.
                Thirty-one women (averaging at least one binge/purge episode per week) were randomly assigned to 20 weeks of dialectical behavior therapy or 20 weeks of a waiting-list comparison condition. The manual-based dialectical behavior therapy focused on training in emotion regulation skills.
                An intent-to-treat analysis showed highly significant decreases in binge/purge behavior with dialectical behavior therapy compared to the waiting-list condition. No significant group differences were found on any of the secondary measures.
                The use of dialectical behavior therapy adapted for treatment of bulimia nervosa was associated with a promising decrease in binge/purge behaviors. We compared cognitive-behavior therapy (CBT) with and without exposure and response prevention (ERP) in the treatment of eating disorder patients who both binged and purged, and reported abnormal attitudes concerning body weight and shape. Both treatments produced significant and comparable reductions in binge-eating and purging, eating patterns, and attitudes about weight and shape at posttreatment. Treatment effects were generalized to improvements in different measures of general psychopathology, and were maintained over follow-ups of 3 and 12 months. The findings are consistent with prior research showing that CBT is an effective treatment for patients with the core features of bulimia nervosa. Furthermore, the data suggest that the addition of in-session exposure and response prevention does not enhance the effectiveness of the basic CBT program. To increase access to cognitive behavioural therapy for bulimia nervosa new delivery modes are being examined. Guided Self-Help (GSH) in primary care is potentially valuable in this respect. This research aimed to compare outcomes following GSH delivered by general practitioners (GPs) in the normal course of their practice to a delayed treatment control (DTC) condition, and to examine the maintenance of treatment gains at 3 and 6 months following completion of GSH.
                Participants were 109 women with full syndrome or sub-threshold bulimia nervosa, randomly allocated to GSH ( n = 54) and DTC ( n = 55). The GSH group received direction and support from a GP over a 17-week period while working through the manual in Bulimia Nervosa and Binge-Eating: A Guide to Recovery by P. J. Cooper (1995). GSH and DTC groups were assessed pre-treatment and 1 week following the 17-week intervention or waiting interval. The GSH group was reassessed at 3- and 6-month follow-up.
                Intention-to-treat analyses at end of treatment revealed significant improvements in bulimic and psychological symptoms in GSH compared with DTC, reduction in mean frequency of binge-eating episodes by 60% in GSH and 6% in DTC, and remission from all binge-eating and compensatory behaviours in 28% of the GSH and 11% of the DTC sample. Treatment gains were maintained at 3- and 6-month follow-up.
                Outcomes in GSH compare favourably with those of specialist-delivered psychological treatments. These findings are considered in light of the nature of the therapy offered and the primary care context. One hundred and thirty-five women with bulimia nervosa participated in a randomized clinical trial designed to determine whether the addition of exposure with response prevention to a core of cognitive-behavioural therapy (CBT) leads to greater clinical improvement and lower risk of relapse. We present results from the end of treatment and 6- and 12-month follow-up.
                Participants received eight sessions of CBT and were then randomized to either exposure to pre-binge cues (B-ERP), exposure to pre-purge cues (P-ERP), or a relaxation training control condition (RELAX).
                CBT produced significant clinical change. At the end of the behavioural treatments, there were no significant differences across the three groups on abstinence (66% in B-ERP, 45% in P-ERP and 47% in RELAX), or frequency of bingeing and purging. B-ERP, but not P-ERP, significantly reduced anxiety on the cue reactivity assessment, food restriction, body dissatisfaction and depression. These differences were not maintained at 6-month follow-up. At 12-months, B-ERP was independently associated with lower food restriction and better global functioning.
                CBT is a highly effective treatment for bulimia nervosa. B-ERP was modestly superior to P-ERP at post-treatment; however, the advantage did not remain throughout the follow-up interval. ERP for bulimia nervosa is an expensive and logistically complicated treatment that does not appear to offer any significant additive benefits that are proportional to the amount of effort required to implement the treatment. Cognitive-behavioral therapy (CBT) has documented efficacy for the treatment of binge eating disorder (BED). Interpersonal psychotherapy (IPT) has been shown to reduce binge eating but its long-term impact and time course on other BED-related symptoms remain largely unknown. This study compares the effects of group CBT and group IPT across BED-related symptoms among overweight individuals with BED.
                One hundred sixty-two overweight patients meeting DSM-IV criteria for BED were randomly assigned to 20 weekly sessions of either group CBT or group IPT. Assessments of binge eating and associated eating disorder psychopathology, general psychological functioning, and weight occurred before treatment, at posttreatment, and at 4-month intervals up to 12 months following treatment.
                Binge-eating recovery rates were equivalent for CBT and IPT at posttreatment (64 [79%] of 81 vs 59 [73%] of 81) and at 1-year follow-up (48 [59%] of 81 vs 50 [62%] of 81). Binge eating increased slightly through follow-up but remained significantly below pretreatment levels. Across treatments, patients had similar significant reductions in associated eating disorders and psychiatric symptoms and maintenance of gains through follow-up. Dietary restraint decreased more quickly in CBT but IPT had equivalent levels by later follow-ups. Patients' relative weight decreased significantly but only slightly, with the greatest reduction among patients sustaining recovery from binge eating from posttreatment to 1-year follow-up.
                Group IPT is a viable alternative to group CBT for the treatment of overweight patients with BED. Although lacking a nonspecific control condition limits conclusions about treatment specificity, both treatments showed initial and long-term efficacy for the core and related symptoms of BED. This study evaluated the effectiveness of group cognitive-behavioral treatment (CBT) and group interpersonal psychotherapy (IPT) for binge eating. Fifty-six women with nonpurging bulimia were randomly assigned to 1 of 3 groups: CBT, IPT, or a wait-list control (WL). Treatment was administered in small groups that met for 16 weekly sessions. At posttreatment, both group CBT and group IPT treatment conditions showed significant improvement in reducing binge eating, whereas the WL condition did not. Binge eating remained significantly below baseline levels for both treatment conditions at 6-month and 1-year follow-ups. These data support the central role of both eating behavior and interpersonal factors in the understanding and treatment of bulimia. The aim of this study was to evaluate the effectiveness of a stepped care approach to the treatment of bulimia nervosa: a self-care manual followed, if necessary, by a course of attenuated cognitive behavioural treatment (CBT) in comparison with standard CBT.
                One hundred and ten patients, presenting at a tertiary referral centre with ICD-10 bulimia nervosa or atypical bulimia nervosa, were randomly assigned to one of two treatment conditions; a) a sequential treatment group: 8 weeks with a self-care manual followed by up to eight sessions of CBT (if still symptomatic) or b) 16 sessions of CBT.
                Bulimic symptoms improved significantly in both groups with no significant differences between the two groups on any of the measures at the end of treatment or at 18 months follow-up. At end of treatment 30% (95% CI: 18-46%) of the sequential group and 30% (95% CI: 17-47%) of the standard treatment group were free from all bulimic symptoms. Sixteen of those in the sequential group improved significantly with self-care and did not require additional treatment. The median number of sessions taken by the sequential group was three (95% CI: 0-6). At 18 months follow-up 40% (95% CI: 23-59%) of the sequential group and 41% (95% CI: 25-59%) of the CBT group were symptom free. Conclusions: A sequential approach to the treatment of bulimia may be as effective as standard CBT and can considerably reduce the amount of therapist contact required. nan To identify predictors of relapse at 6-month follow-up for women with binge eating disorder (BED).
                Participants were 32 women with BED who had initially achieved abstinence from binge eating after 20 weeks of dialectical behavior therapy (DBT) adapted for patients with BED. Posttreatment predictor variables included the subscales Restraint, Weight Concerns, and Shape Concerns from the Eating Disorders Examination (EDE), the Emotional Eating Scale score, the Rosenberg Self-Esteem Scale, body mass index, and early versus late age of binge eating onset.
                The largest effect sizes for predicting relapse were found with early onset of binge eating and higher EDE Restraint scores.
                Previous findings that earlier age of onset (age 16 years or younger) is linked to less successful treatment outcome are now extended to the 6-month follow-up assessment. The finding that higher restraint scores after treatment predict relapse adds to the literature concerning the role of restraint in patients with BED.
                Copyright 2002 by Wiley Periodicals, Inc. This study examined the relative efficacy of cognitive-behavioral and behavioral treatment approaches for bulimia nervosa. Female bulimic Ss were randomly assigned to cognitive-behavioral, behavioral, or attention placebo conditions. At posttreatment, 92% of the cognitive-behavioral group, 100% of the behavioral group, and 69% of the nonspecific self-monitoring group were abstinent from binge eating-purging. At 6-month follow-up, 69% of the cognitive-behavioral group, 38% of the behavioral group, and 15% of the nonspecific self-monitoring group were abstinent from binge eating and purging. The results support the conceptualization of bulimia nervosa as a multifaceted disorder best treated with an approach that directly addresses maladaptive cognitions, problematic behaviors, and the development of more adaptive coping skills. The specificity and magnitude of the effects of cognitive behavior therapy in the treatment of bulimia nervosa were evaluated. Seventy-five patients who met strict diagnostic criteria were treated with either cognitive behavior therapy, a simplified behavioral version of this treatment, or interpersonal psychotherapy. Assessment was by interview and self-report questionnaire, and many aspects of functioning were evaluated. All three treatments resulted in an improvement in the measures of the psychopathology. Cognitive behavior therapy was more effective than interpersonal psychotherapy in modifying the disturbed attitudes to shape and weight, extreme attempts to diet, and self-induced vomiting. Cognitive behavior therapy was more effective than behavior therapy in modifying the disturbed attitudes to shape and weight and extreme dieting, but it was equivalent in other respects. The findings suggest that cognitive behavior therapy, when applied to patients with bulimia nervosa, operates through mechanisms specific to this treatment and is more effective than both interpersonal psychotherapy and a simplified behavioral version of cognitive behavior therapy. The study compared the efficacy of self-help without and with guidance (referred to as 'pure' and 'guided' self-help), using a cognitive behavioral self-help manual (Fairburn, 1995) for binge eating.
                A sample of 31 participants with bulimia nervosa, subthreshold bulimia nervosa and binge-eating disorder were assigned randomly to one of the self-help levels for 16 weeks, after four weeks of baseline observations.
                The results indicated that both forms of self-help treatments had a modestly positive and sustained effect on the participants' eating problems. Intention-to-treat analyses showed that participants reduced their mean number of objective bulimic episodes and purging behaviour by 33% and 17% over the course of the treatment. The corresponding reduction levels for the treatment completers (N = 18) were 58% and 61%, respectively. Furthermore, there were no significant differences between the pure and guided self-help groups in terms of outcome, reflecting the probable insignificance of guidance for the broader group of individuals with binge-eating problems. At follow-up, no further significant improvement or deterioration was observed in the ensuing six months compared with the post-treatment data.
                Given the heterogeneity of the diagnostic groups in the present study, resulting in high external validity, and the conservative nature of the analyses, self-help is discussed as a viable means of initial treatment for binge eating. Conduct a randomized treatment trial to test whether healthy dieting maintains bulimic symptoms or effectively reduces this eating disturbance.
                Female participants (n=85) with full- and sub-threshold bulimia nervosa were randomly assigned to a 6-session healthy dieting intervention or waitlist condition and assessed through 3-month follow-up.
                Relative to control participants, intervention participants showed modest weight loss during treatment and demonstrated significant improvements in bulimic symptoms that persisted through follow-up.
                These preliminary results suggest that this intervention shows potential for the treatment of bulimia nervosa and may be worthy of future refinement and evaluation. Results also provide experimental evidence that dieting behaviors do not maintain bulimia nervosa, suggesting the need to reconsider maintenance models for this eating disorder. Research suggests that cognitive-behavioral therapy (CBT) is the most effective psychotherapeutic treatment for bulimia nervosa. One exception was a study that suggested that interpersonal psychotherapy (IPT) might be as effective as CBT, although slower to achieve its effects. The present study is designed to repeat this important comparison.
                Two hundred twenty patients meeting DSM-III-R criteria for bulimia nervosa were allocated at random to 19 sessions of either CBT or IPT conducted over a 20-week period and evaluated for 1 year after treatment in a multisite study.
                Cognitive-behavioral therapy was significantly superior to IPT at the end of treatment in the percentage of participants recovered (29% [n=32] vs 6% [n=71), the percentage remitted (48% [n=53] vs 28% [n = 31]), and the percentage meeting community norms for eating attitudes and behaviors (41% [n=45] vs 27% [n=30]). For treatment completers, the percentage recovered was 45% (n= 29) for CBT and 8% (n= 5) for IPT. However, at follow-up, there were no significant differences between the 2 treatments: 26 (40%) CBT completers had recovered at follow-up compared with 17 (27%) IPT completers.
                Cognitive-behavioral therapy was significantly more rapid in engendering improvement in patients with bulimia nervosa than IPT. This suggests that CBT should be considered the preferred psychotherapeutic treatment for bulimia nervosa. The authors investigated the applicability of self psychological treatment (SPT) and cognitive orientation treatment (COT) to the treatment of anorexia and bulimia. Thirty-three patients participated in this study. The bulimic patients (n = 25) were randomly assigned either to SPT, COT, or control/nutritional counseling only (C/NC). The anorexic patients (n = 8) were randomly assigned to either SPT or COT. Patients were administered a battery of outcome measures assessing eating disorders symptomatology, attitudes toward food, self structure, and general psychiatric symptoms. After SPT, significant improvement was observed. After COT, slight but nonsignificant improvement was observed. After C/NC, almost no changes could be detected. The aim of this study was to determine the efficacy of cognitive-behavioral therapy (CBT) and behavioral weight loss treatment (BWLT) for overweight patients with binge eating disorder (BED).
                Eighty obese patients meeting criteria of BED according to DSM-IV-TR were randomly assigned to either CBT or BWLT consisting of 16 weekly treatments and 6 monthly follow-up sessions. Binge eating, general psychopathology, and body mass index (BMI) were assessed before, during, and after treatment, and at 12-month follow-up.
                At posttreatment results favored CBT as the more effective treatment. Analysis of the course of treatments pointed to a faster improvement of binge eating in CBT based on the number of self-reported weekly binges, but faster reduction of BMI in BWLT. At 12-month follow-up, no substantial differences between the two treatment conditions existed.
                CBT was somewhat more efficacious than BWLT in treating binge eating but this superior effect was barely maintained in the long term. Further research into cost effectiveness is needed to assess which treatment should be considered the treatment of choice.
                2006 by Wiley Periodicals, Inc. This study compared the effectiveness of cognitive therapy (CT), nutritional therapy (NT), the combination of cognitive and nutritional therapy (CNT), against a control condition of support group (SG) in the treatment of bulimia nervosa.
                One hundred female out-patients who fulfilled DSM-III-R criteria for bulimia nervosa were randomized to the four treatment groups. NT and CT were designed to cover different areas with minimal overlap, and CNT provided all of the features of both of these treatments. The control condition was conducted in a group self-help format. Each of the treatments lasted 14 weeks.
                All three active treatments as well as SG produced significant decreases in binge/vomit episodes. Intent-to-treat analysis found CNT and CT to be significantly more effective than SG in retaining subjects in treatment and completion of study, as well as in producing greater improvements in dysfunctional attitudes and self-control. CNT was superior to SG in achieving abstinence from bulimic behaviour. NT was superior to SG only in increase of self-control. Logistic regression found that the cognitive component, whether given alone or in conjunction with NT, and higher pre-treatment self-control scores were significant predictors for both completion of study and abstinence.
                CT (either alone, or in combination with nutritional therapy) remains the treatment of choice for bulimia nervosa. A treatment escalation approach should be tested for the treatment of bulimia with the more intensive and less widely available CT (with or without nutritional counselling) offered after patients have failed the less intensive and more widely available support group treatment. This study compared the relative short- and longer-term efficacy of therapist-guided and unguided use of a cognitive behavioral self-help manual for binge eating [Fairburn, C. G. (1995). Overcome binge eating. New York: The Guilford Press.] Forty women (82.5% with binge eating disorder) were randomized to one of the two treatment levels. Results indicate that both conditions represent viable means of treating binge eating. Overall, patients improved their eating behavior, eliminated any inappropriate compensatory behaviors, reduced their shape concern, weight concern, and other symptoms of eating-related psychopathology, and improved their general psychological functioning. The guided self-help condition was notably superior in reducing the occurrence of binge eating and its associated symptomatology, as well as lowering interpersonal sensitivity. A high degree of general psychopathology was a negative prognostic indicator. The implications for a stepped-care approach to treating binge eating are discussed. nan The aim of this treatment study on bulimia nervosa was (i) to examine the effect of physical exercise as an experimental treatment condition against the well-documented effect of cognitive-behavioral therapy (CBT), and (ii) to compare the effect of CBT versus the effect of nutritional advice as one single treatment component of CBT.
                Normal weight female bulimic patients aged 18-29 yr were randomly assigned to a physical exercise program (N = 15), CBT (N = 16), nutritional advice (N = 17), or a waiting list control group (N = 16). Seventeen healthy female control subjects were also included. Treatment effects were determined by the frequency of binge eating and purging, scores on the Eating Disorder Inventory subscales "Drive for thinness," "Bulimia," and "Body dissatisfaction" and by a clinical interview to measure symptom severity. Assessments were made before and after treatment and at 6- and 18-month follow-up after the end of treatment.
                Nutritional counseling did not prove more effective than CBT. Physical exercise appeared more effective than CBT in reducing pursuit of thinness; change in body composition; aerobic fitness; and frequency of bingeing, purging, and laxative abuse.
                Physical exercise is important in the treatment of normal weight bulimic patients. Further studies should address possible additive effects of CBT and physical exercise. The authors examined the effectiveness of unguided self-help as a first step in the treatment of bulimia nervosa.
                A total of 85 women with bulimia nervosa who were on a waiting list for treatment at a hospital-based clinic participated. The patients were randomly assigned to receive one of two self-help manuals or to a waiting list control condition for 8 weeks. One of the self-help manuals addressed the specific symptoms of bulimia nervosa (cognitive behavior self-help), while the other focused on self-assertion skills (nonspecific self-help).
                Twenty patients (23.5%) dropped out of the study. The data were analyzed with intention-to-treat analysis. Although the group-by-time interaction for binge eating and purging was not statistically significant, simple effects showed that there was a significant reduction in symptom frequency in both self-help conditions at posttreatment but not in the waiting list condition. There were no statistically significant changes in levels of dietary restraint, eating concerns, concerns about shape and weight, or general psychopathology. A greater proportion of patients in the cognitive behavior self-help (53.6%) and nonspecific self-help (50.0%) conditions reported at least a 50% reduction in binge eating or purging at posttreatment, compared with the waiting list condition (31.0%). A lower baseline knowledge about eating disorders, more problems with intimacy, and higher compulsivity scores predicted a better response.
                The findings suggest that a subgroup of patients with bulimia nervosa may benefit from unguided self-help as a first step in their treatment. Cognitive behavior self-help and nonspecific self-help had equivalent effects. The aim of the current study was to evaluate whether guided self-help was effective in the short and long term in the treatment of bulimia nervosa.
                Eighty-one patients with bulimia nervosa were randomly assigned to either a self-help manual with a maximum of 18 short weekly visits (guided self-help) or to 18 weekly 1.5-h sessions of cognitive-behavioral group therapy (CBT). The primary outcome variables were monthly frequencies of self-reported binge eating and vomiting episodes. Secondary outcome variables were eating disorder-related psychopathology (assessed with the Eating Disorders Inventory [EDI]) and depression (assessed by the Beck Depression Inventory [BDI]). Patients were followed up 1 year after the end of treatment.
                A mixed-effects linear regression analysis indicated that subjects in both treatment conditions showed a significant decrease over time in binge eating and vomiting frequencies, in the scores of the EDI subscales, and in the BDI. Both treatment modalities led to a sustained improvement at follow-up. A separate analysis of the completer sample showed significantly higher remission rates in the self-help condition (74%) compared with the CBT condition (44%) at follow-up.
                Guided self-help incorporating the use of a self-help manual offers an approach that can be effective in the short and long-term treatment of bulimia nervosa.
                Copyright 2004 by Wiley Periodicals, Inc. Int J Eat Disord 35: 522-537, 2004. There is great potential demand for treatment of bulimia nervosa and binge eating disorder. Skilled therapists are in short supply. Self-help and guided self-help based upon books have shown some promise as an economical alternative to full therapy in some cases.
                To investigate the efficacy and effectiveness of self-help with and without guidance in a specialist secondary service.
                A randomised controlled trial comparing three forms of self-help over 4 months with a waiting-list comparison group and measurement of service consumption over the subsequent 8 months.
                Self-help delivered with four sessions of face-to-face guidance led to improved outcome over 4 months. There is also some evidence to support the use of telephone guidance. A minority of participants achieved lasting remission of their disorder in relation to self-help, but there was no significant difference in final outcome between the groups after they had progressed through the stepped care programme. Patients initially offered guided self-help had a lower long-term drop-out rate.
                Guided self-help is a worthwhile initial response to bulimia nervosa and binge eating disorder. It is a treatment that could be delivered in primary care and in other non-specialist settings.
There is a small body of evidence for the efficacy of CBT in bulimia nervosa and similar syndromes, but the quality of trials is very variable and sample sizes are often small. More and larger trials are needed, particularly for binge eating disorder and other EDNOS syndromes. There is a need to develop more efficacious therapies for those with both a weight and an eating disorder.
