A significant percentage of children with disruptive behavior disorders do not receive mental health assistance. Utilization is lowest among groups whose children are at greatest risk. To increase the availability, accessibility, and cost efficacy of parent training programs, this prospective randomized trial compared a large group community-based parent training program to a clinic-based individual parent training (PT) programs. All families of junior kindergartners in the Hamilton public and separate school boards were sent a checklist regarding problems at home. Those returning questionnaires above the 90th percentile were block randomly assigned to: (1) a 12-week clinic-based individual parent training (Clinic/Individual), (2) a 12-week community-based large group parent training (Community/Group), or (3) a waiting list control condition. Immigrant families, those using English as a second language, and parents of children with severe behaviour problems were significantly more likely to enroll in Community/Groups than Clinic/Individual PT. Parents in Community/Groups reported greater improvements in behaviour problems at home and better maintenance of these gains at 6-month follow-up. A cost analysis showed that, with groups of 18 families, Community/Groups are more than six times as cost effective as Clinic/Individual programs. To test effectiveness of a parenting intervention, delivered in a community-based voluntary-sector organisation, for reducing conduct problems in clinically-referred children.
                Randomised controlled trial, follow-up at 6, 18 months, assessors blind to treatment status. Participants--76 children referred for conduct problems, aged 2-9, primarily low-income families, randomised to treatment vs. 6-month wait-list group. Retention was 93% at 6 months, 90% at 18 months. Interventions--Webster-Stratton Incredible Years video-based 14-week group programme, teaches cognitive-behavioural principles for managing behaviour, using a collaborative, practical, problem-solving approach. Primary outcomes--child problem behaviour by parent-report (Eyberg) and home-based direct observation; secondary outcomes--observed positive and negative parenting; parent-reported parenting skill, confidence and depression.
                Post-treatment improvements were found in child problem behaviour, by parent-report (effect size (ES) .48, p = .05) and direct observation (ES .78, p = .02); child independent play (ES .77, p = .003); observed negative (ES .74, p = .003) and positive (ES .38, p = .04) parenting; parent-reported confidence (ES .40, p = .03) and skill (ES .65, p =.01), using ANCOVA to control for baseline scores. Maternal depression did not change. Consumer satisfaction was high. At 18-month follow-up, although no randomised comparison was possible, changes appeared to maintain, with no significant change toward baseline level on any measure. Change in observed positive parenting appeared to mediate change in child problem behaviour (p < .025).
                Findings suggest that a group-based cognitive-behavioural parenting programme, delivered by well-trained and supervised staff, can be effective in a community voluntary-sector setting, for reducing conduct problems and enhancing parenting skills. Change in parenting skill appears to be a key mechanism for change in child behaviour. Findings have implications for feasibility of translating evidence-based programmes, even for clinically-referred conduct problems, into less specialised community settings, likely to have lower costs and be more accessible for families. To investigate the effectiveness of behavioral parent training (BPT) as adjunct to routine clinical care (RCC).
                After a first phase of RCC, 94 children with attention-deficit/hyperactivity disorder (ADHD) ages 4-12, all referred to a Dutch outpatient mental health clinic, were randomly assigned to 5 months of BPT plus concurrent RCC (n = 47) or to 5 months of RCC (n = 47) alone. BPT consisted of 12 sessions in group format; RCC included family support and pharmacotherapy when appropriate. Exclusionary criteria were minimized, and children with and without medication could participate. Parent-reported behavioral problems, ADHD symptoms, internalizing problems, and parenting stress were assessed before and after treatment. Follow-up assessment of the BPT + RCC group was completed 25 weeks post-BPT intervention. Repeated-measures analyses of variance were carried out on an intention-to-treat basis.
                Both groups showed improvements over time on all measures. BPT + RCC was superior to RCC alone in reducing behavioral (p = .017) and internalizing (p = .042) problems. No outcome differences were found in ADHD symptoms (p = .161) and parenting stress (p = .643). These results were equal for children with and without medication. Children allocated to RCC alone received more polypharmaceutical treatment.
                Adjunctive BPT enhances the effectiveness of routine treatment of children with ADHD, particularly in decreasing behavioral and internalizing problems, but not in reducing ADHD symptoms or parenting stress. Furthermore, adjunctive BPT may limit the prescription of polypharmaceutical treatment. Members of families headed by single mothers are at increased risk of psychosocial disadvantage and mental health problems. We assessed the effect of a community-based program of social support and education groups for single mothers of young children on maternal well-being and parenting.
                We recruited 116 single mothers of children 3 to 9 years old through community advertisements. Eligible mothers were randomly assigned either to participate in a 10-week program of group sessions (1.5 hours per week) offering social support and education, with a parallel children's activity group, or to receive a standard list of community resources and the option to participate in group sessions at the end of the follow-up period. Interviewers blinded to the randomization collected assessment data from all mothers at baseline and at 3 follow-up visits (immediately after the intervention and at 3 and 6 months after the intervention). Outcome measures were self-reported mood, self-esteem, social support and parenting.
                Between February 2000 and April 2003, the program was offered to 9 groups of single mothers. Most of the mothers in the trial reported high levels of financial and mental health problems. In the short term (after the intervention), mothers in the intervention group had improved scores for mood (p < 0.01, standardized effect = 0.55) and self-esteem (p < 0.05, standardized effect = 0.29) compared with mothers in the control group; scores for the other 2 measures did not differ between the groups. Growth curve analysis of program effects over the follow-up period showed improvement in all 4 outcomes, with no significant difference between the intervention and control groups.
                This community-based program of group sessions offering social support and education to low-income single mothers had positive short-term effects on mood and self-esteem but not on social support and parenting. Longer follow-up showed attenuation of these effects. The typical pattern for intervention outcome studies for conduct problems has been for effect sizes to dissipate over time with decreasing effects across subsequent follow-ups.
                To establish whether the short-term positive effects of a parenting programme are sustained longer term. To observe trends, and costs, in health and social service use after intervention.
                Parents with children aged 36-59 months at risk of developing conduct disorder (n = 104) received intervention between baseline and first follow-up (6 months after baseline n = 86) in 11 Sure Start areas in North Wales. Follow-ups two (n = 82) and three (n = 79) occurred 12 and 18 months after baseline. Child problem behaviour and parenting skills were assessed via parent self-report and direct observation in the home.
                The significant parent-reported improvements in primary measures of child behaviour, parent behaviour, parental stress and depression gained at follow-up one were maintained to follow-up three, as were improved observed child and parent behaviours. Overall, 63% of children made a minimum significant change (0.3 standard deviations) on the Eyberg Child Behavior Inventory problem scale between baseline and follow-up (using intention-to-treat data), 54% made a large change (0.8 standard deviations) and 39% made a very large change (1.5 standard deviations). Child contact with health and social services had reduced at follow-up three.
                Early parent-based intervention reduced child antisocial behaviour and benefits were maintained, with reduced reliance on health and social service provision, over time. The effect of a short-term group intervention to reduce self-blame and guilt in parents of children with severe disabilities was examined. Thirty-four mothers were randomly assigned to treatment and waiting list control groups. They participated in classes led by a counselor on topics relating to cognitive processes associated with guilt and self-blame. Results showed significant reductions in measures of guilt, negative automatic thoughts, internal negative attributions, and depression. Theoretical and treatment literature concerning self-blame and guilt was briefly reviewed and the derivative treatment was described. This study provides evidence of the effectiveness of behaviorally based parenting skills classes provided by carefully trained and supervised group leaders who were not mental health clinicians. A program for parents of at-risk middle school students was evaluated in a randomized controlled trial in 8 small Oregon communities. Parents (N = 303) were randomly assigned to immediate treatment or a wait-list condition. Data were analyzed using latent growth modeling. Participation in the program led to significant improvements in problem-solving interactions as indicated by parent reports and a Taped Situations Test. Parents' over-reactivity and laxness toward their children's behavior were reduced and their feelings toward their children improved significantly as a function of treatment. Parent-reported child antisocial behavior was also reduced. This study examined the efficacy of a brief 2-h discussion group for parents of preschool children that show disruptive behavior on shopping trips. Forty-six parents with children aged 2-6 years were randomly assigned to either the intervention condition or a waitlist control group. Significant intervention effects were found for measures of problem child behavior, dysfunctional parenting styles and parents' confidence in the parenting role. No group differences were found for parental adjustment or conflict over parenting. Intervention gains were maintained at 6-month follow-up. Results are discussed within a primary care and public health framework. A pilot trial provided some evidence that the Triple P Positive Parenting Program is effective with and acceptable to a Japanese population in Australia (Matsumoto, Sofronoff, & Sanders, 2007). This effectiveness study aimed to address theoretical and practical concerns related to the parent training program in community settings in Japan. The research used community resources within an ecological framework. Fifty-four Japanese families living in a Tokyo metropolitan area were randomly assigned to either a treatment or a wait-list control group. Program effects and acceptability were examined and then compared with the outcomes from the trial with Japanese parents living in Australia. The results showed significant program effects and high levels of acceptability of the program and core parenting skills, which was consistent with the pilot trial. The findings provided support for the effectiveness and sociocultural validation of Triple P in Japanese society. Intervention effects and program acceptability as well as limitations and future research are discussed. This report discusses the development of a coping skill training program for parents of substance-abusing adolescents and presents preliminary data on the effects of the program on parent functioning and adolescent substance use. The behavioral-analytic model of program development was used to sample representative problematic situations experienced by parents of substance-abusing adolescents, obtain an effectiveness-scaling of responses to these situations, and derive alternate forms of a situational role-play measure of parental coping. These situations and scoring guidelines were then used to create the skill training program. Parents of substance-abusing adolescents not in treatment subsequently were randomly assigned in a pilot investigation to either a skill training or delayed treatment condition. Skill training resulted in significant improvement in parental coping skills relative to delayed treatment. Moderate to large improvement in the parent's report of their own functioning, family communication, and the teen's marijuana use also favored the skill training group. Despite recognition of the need for parenting interventions to prevent childhood behavioral problems, few community programs have been evaluated. This report describes the randomized controlled evaluation of a four-session psychoeducational group for parents of preschoolers with behavior problems, delivered in community agencies.
                In 1998, 222 primary caregivers, recruited through community ads, filled out questionnaires on parenting practices and child behavior. Parents were randomly assigned to immediate intervention or a wait-list control. The intervention comprised three weekly group sessions and a 1-month booster, the focus being to support effective discipline (using the video 1-2-3 Magic) and to reduce parent-child conflict.
                Using an intent-to-treat analysis, repeated-measures analyses of variance indicated that the parents who received the intervention reported significantly greater improvement in parenting practices and a significantly greater reduction in child problem behavior than the control group. The gains in positive parenting behaviors were maintained at 1-year follow-up in a subset of the experimental group.
                This brief intervention program may be a useful first intervention for parents of young children with behavior problems, as it seems both acceptable and reasonably effective. The effectiveness of a parent training program for promoting positive parent-child relationships was examined among families of 2-year-olds. Forty-six mothers and fathers and their toddlers were assigned to either an intervention or comparison group. Intervention group parents participated in a 10-week program that focused on principles for effectively interacting with their toddlers. Parents completed measures of parenting self-efficacy, depression, stress, and perceptions of their toddler's behaviors and were videotaped playing with their toddlers preintervention, postintervention, and 3 months following the intervention. Repeated measures ANOVAs showed that the parent training program led to significant increases in maternal self-efficacy, decreases in maternal stress, and improvements in the quality of mother-toddler interactions. No significant effects were found among fathers. Explanations for obtaining different outcomes for mothers and fathers are discussed and directions for future research are recommended. An adaptation of the Coping With Depression Course (CWDC) was evaluated in mothers of children with attention-deficit/hyperactivity disorder (ADHD), a population at risk for depression. Mothers were randomly assigned to receive the CWDC either immediately following an intensive summer treatment program targeting their child's behavior or after a wait-list period. Measures of maternal functioning, cognitions about child behavior, parent-child and marital relationship quality, child behavior, and ADHD-related family impairment were obtained at pretreatment, posttreatment, and 5-month follow-up. The CWDC resulted in improvements in maternal depressive symptoms, maternal self-esteem, child-related cognitions, and family impairment at posttreatment compared to a wait-list control group that were maintained at follow-up. Findings suggest that the CWDC is a promising intervention for mothers of children with ADHD, particularly those with current depressive symptomatology. The authors tested a 12-week parent training program with parents (n = 208) and teachers (n = 77) of 2-3-year-olds in day care centers serving low-income families of color in Chicago. Eleven centers were randomly assigned to 1 of 4 conditions: (a) parent and teacher training (PT + TT), (b) parent training (PT), (c) teacher training (TT), and (d) waiting list control (C). After controlling for parent stress, PT and PT + TT parents reported higher self-efficacy and less coercive discipline and were observed to have more positive behaviors than C and TT parents. Among toddlers in high-risk behavior problem groups, toddlers in the experimental conditions showed greater improvement than controls. Most effects were retained 1 year later. Benefits were greatest when parents directly received training. Parenting programmes have been shown to improve children's adjustment and reduce problem behaviour; however, little research has addressed outcomes for Indigenous families. The aim of this project was to assess the impact and cultural appropriateness of a parenting programme tailored for Indigenous families, an adaptation of the evidence-based Group Triple P - Positive Parenting Program.
                A repeated measures randomised group design methodology was used, comparing the intervention with a waitlist control condition pre- and post-intervention, with a 6-month follow-up of the intervention group.
                Parents attending Group Triple P reported a significant decrease in rates of problem child behaviour and less reliance on some dysfunctional parenting practices following the intervention in comparison to waitlist families. The programme also led to greater movement from the clinical range to the non-clinic range for mean child behaviour scores on all measures. Effects were primarily maintained at 6-month follow-up. Qualitative data showed generally positive responses to the programme resources, content and process. However, only a small number of waitlist families subsequently attended groups, signalling the importance of engaging families when they first make contact, helping families deal with competing demands, and offering flexible service delivery so families can resume contact when circumstances permit.
                This study provides empirical support for the effectiveness and acceptability of a culturally tailored approach to Group Triple P conducted by Child Health and Indigenous Health workers in a community setting. The outcomes of this trial may be seen as a significant step in increasing appropriate service provision for Indigenous families and reducing barriers to accessing available services in the community. Behavioural parent training is effective in improving child disruptive behavioural problems in preschool children by increasing parenting competence. The indicated Prevention Programme for Externalizing Problem behaviour (PEP) is a group training programme for parents and kindergarten teachers of children aged 3-6 years with externalizing behavioural problems.
                To evaluate the effects of PEP on child problem behaviour, parenting practices, parent-child interactions, and parental quality of life.
                Parents and kindergarten teachers of 155 children were randomly assigned to an intervention group (n = 91) and a nontreated control group (n = 64). They rated children's problem behaviour before and after PEP training; parents also reported on their parenting practices and quality of life. Standardized play situations were video-taped and rated for parent-child interactions, e.g. parental warmth.
                In the intention to treat analysis, mothers of the intervention group described less disruptive child behaviour and better parenting strategies, and showed more parental warmth during a standardized parent-child interaction. Dosage analyses confirmed these results for parents who attended at least five training sessions. Children were also rated to show less behaviour problems by their kindergarten teachers.
                Training effects were especially positive for parents who attended at least half of the training sessions.
                CBCL: Child Behaviour Checklist; CII: Coder Impressions Inventory; DASS: Depression anxiety Stress Scale; HSQ: Home-situation Questionnaire; LSS: Life Satisfaction Scale; OBDT: observed behaviour during the test; PCL: Problem Checklist; PEP: prevention programme for externalizing problem behaviour; PPC: Parent Problem Checklist; PPS: Parent Practices Scale; PS: Parenting Scale; PSBC: Problem Setting and Behaviour checklist; QJPS: Questionnaire on Judging Parental Strains; SEFS: Self-Efficacy Scale; SSC: Social Support Scale; TRF: Caregiver-Teacher Report Form. First-time parent couples from childbirth classes were randomly assigned to a four-session training group (n = 29) or a control group (n = 31). Members of the training group were taught behavioral strategies to promote healthy, self-sufficient sleep patterns in their infants, whereas the control group received the same amount of personal contact without the behavioral training. Six sleep variables were derived from a daily infant sleep diary completed by parents at two time points. Results show that at age 6-9 weeks, infants in the training group displayed significantly better sleeping patterns than did control infants. Training group parents awakened and responded less often to infant signaling and reported greater parental competence. By contrast, control group parents indicated increased stress over time. nan Parents of gifted children identify a need for tailored parenting support, and gifted children have unique requirements and vulnerabilities. The aim of this study was to assess the efficacy of a tailored behavioural parenting intervention, for enhancing the parenting skills of parents of gifted children and to assess the effect of these changes on the behavioural and emotional adjustment of their gifted child. A randomised controlled trial of tailored Group Triple P - Positive Parenting Program was conducted with 75 parents of children identified as gifted. Results indicated significant intervention effects for the number and frequency of parent reported child behaviour problems, as well as hyperactivity in the intervention group, relative to a waitlist control. Parents also reported significant improvements in their own parenting style, including less permissiveness, harshness, and verbosity when disciplining their child. No intervention effects were evident for teacher reports, except for a trend in relation to hyperactivity. This study demonstrated that a tailored behavioural parenting intervention is effective and acceptable for parents of gifted children, and thus has clinical implications for the delivery of parenting interventions for this population. Controlling, uninvolved, and rejecting parenting in early childhood are strong predictors of later disruptive behavior disorders. However, there have been no evaluations of non-targeted groups for parents of very young children, despite their potential advantages.
                We randomly assigned 79 mothers of 12- to 36-month-olds to an 8-session parent training program (called 'COPEing with Toddler Behaviour') or to a waiting list control condition. We investigated the immediate and short-term impact on parent-reported child behavior problems, observed parent-child interaction, and self-reported parenting behavior and parent functioning.
                In an intent-to-treat design, the program yielded significant effects on child behavior problems, positive parent-child interaction, and parental overreactivity and depression but not observed negative child behavior or parental laxness. Most effects were significant at both post-test and 1-month follow-up and effects sizes were small to medium for the intervention group and inverse to small for the control group.
                The potential of the program to prevent later behavior problems is supported by improvements in six of the eight outcomes. As part of a community strategy, groups such as COPEing with Toddler Behaviour may promote positive parent-child interaction and children's mental health. To assess the effectiveness of a parenting programme, delivered by health visitors in primary care, in improving the mental health of children and their parents among a representative general practice population.
                Parents of children aged 2-8 years who scored in the upper 50% on a behaviour inventory were randomised to the Webster-Stratton 10 week parenting programme delivered by trained health visitors, or no intervention. Main outcome measures were the Eyberg Child Behaviour Inventory and the Goodman Strengths and Difficulties Questionnaire to measure child behaviour, and the General Health Questionnaire, Abidin's Parenting Stress Index, and Rosenberg's Self Esteem Scale to measure parents' mental health. These outcomes were measured before and immediately after the intervention, and at six months follow up.
                The intervention was more effective at improving some aspects of the children's mental health, notably conduct problems, than the no intervention control condition. The Goodman conduct problem score was reduced at immediate and six month follow up, and the Eyberg Child Behaviour Inventory was reduced at six months. The intervention also had a short term impact on social dysfunction among parents. These benefits were seen among families with children scoring in the clinical range for behaviour problems and also among children scoring in the non-clinical (normal) range.
                This intervention could make a useful contribution to the prevention of child behaviour problems and to mental health promotion in primary care. To determine whether a parenting programme, offered universally in primary care, can prevent behavioural problems in children and improve parenting and maternal mental health.
                Cluster randomised trial.
                40 primary care nursing centres (clusters) in Victoria, Australia.
                733 English speaking mothers of 8 month old children sequentially recruited from well child appointments; 656 retained at 24 months.
                Structured three session programme at age 8-15 months, co-led by well child providers and a parenting expert. The programme covered normal development and behaviour, strategies to increase desired behaviour, and strategies to reduce unwanted behaviour.
                Maternal report of child externalising behaviour (child behavior checklist 1(1/2)-5 year old), parenting (parent behavior checklist), and maternal mental health (depression anxiety stress scales) at 18 and 24 months.
                At 18 months, child behaviour and parenting scores were similar in the two groups. At 24 months, externalising scores in the intervention and control groups were similar (mean 11.9 (SD 7.2) v 12.9 (7.4)); however, on the parent behavior checklist subscale scores, intervention group parents were less likely to report harsh/abusive parenting (mean 38.9 (SD 7.7) v 40.5 (8.8); adjusted mean difference -1.83, 95% confidence interval -3.12 to -0.55) and unreasonable expectations of child development (40.9 (9.9) v 42.7 (9.6); -2.18, -3.74 to -0.62). Mean scores for nurturing parenting and maternal mental health were similar in the two groups at both times.
                A universal parenting programme resulted in modest improvement in parenting factors that predict behavioural problems in children but did not reduce externalising behavioural problems or affect maternal mental health at 2 years. Trial registration ISRCTN 77531789. An experimental research study was done to determine whether an educational intervention about attention deficit hyperactivity disorder (ADHD) would improve a mother's knowledge about ADHD and her feelings of competence as a parent. 20 low socioeconomic status mothers who had a male child between the ages of 5 and 11 diagnosed with ADHD and placed on methylphenidate were randomly selected for the study. An experimental group of 10 mothers was given a 5-week educational intervention on ADHD; the remaining 10 mothers served as a control group. Differences between the experimental and non-experimental mothers in knowledge and opinions about ADHD and parental sense of competency were measured. Scores improved in parental satisfaction and parental sense of competency in mothers who participated in the educational intervention. The research findings support the idea that nurses can assist a family in learning and dealing with their child's ADHD, a chronic condition. The efficacy of group parent training was assessed in improving compliance and time on task in preschoolers with attention-deficit disorder with hyperactivity. Positive effects were obtained on measures of child compliance, but not on measures of attention. Parental compliance-management skills and overall style of interaction were also positively affected. The use of parent training for early intervention with ADDH children is discussed. In a randomized prevention trial, 238 recently separated mothers and their young sons were assigned to either Parent Management Training (PMT) or a comparison group. Families were intensively assessed at baseline and at each 6-month interval through 30 months. To understand the effects of PMT, we first evaluated effect sizes among family variables over time. Second, because observed parenting was the target of PMT, we hypothesized a sequential pattern of structured changes within and between individuals. Using constructs with mismatched sources of data, we conducted a set of latent growth mediational analyses to test hypothesized mechanisms explaining change. Effect sizes indicated that parenting changed first within 12 months, followed by changes in boy behaviors and finally changes in maternal depression within 30 months. Unique follow-up findings indicated that intervention effects on reductions in maternal depression were mediated by reductions in boy externalizing; intervention effects on externalizing were mediated by reductions in boy depression. As expected, increases in effective parenting predicted reductions in child behavior problems. PMT effects on internalizing were direct and indirect, partially mediated by parenting practices. Results are discussed from a system's perspective on PMT amplifiers. The efficacy of the Incredible Years parent training and child therapy programs was examined in a randomized controlled study including 127 Norwegian children aged 4-8 years. Children diagnosed with oppositional defiant disorder (ODD) or conduct disorder (CD) were randomized to parent training (PT), parent training combined with child therapy (PT + CT), or a waiting-list control condition (WLC). Assessments were carried out at baseline, posttreatment and at a one-year follow-up using standardized measures and a semi-structured interview. Both active treatment conditions reduced child conduct problems posttreatment as opposed to the WLC, while differences between the two treatment conditions were small and nonsignificant. About two thirds of the treated children functioned within normal variation after treatment, and the same proportion no longer received an ODD diagnosis at the one-year follow-up. Parental use of positive strategies increased after treatment, and the use of harsh and inconsistent discipline decreased as did mother experience of stress. The outcome of this study emphasizes the importance of offering parent training to young children with severe conduct problems exhibited at home. The findings and usefulness of the Incredible Years program in the present Norwegian replication study further support and extend positive outcomes of previous controlled trials conducted primarily in Anglo-Saxon countries.
The findings of this review support the use of parenting programmes to improve the short-term psychosocial wellbeing of parents. Further input may be required to ensure that these results are maintained. More research is needed that explicitly addresses the benefits for fathers, and that examines the comparative effectiveness of different types of programme along with the mechanisms by which such programmes bring about improvements in parental psychosocial functioning.
