BACKGROUND: This metaregression analysis examined which behavioral techniques that are commonly used in behavioral parent and teacher training programs for children with attention-deficit/hyperactivity disorder (ADHD) were related to program effectiveness on children's behavioral outcomes. METHODS: We included 32 randomized controlled trials (N = 2594 children) investigating behavioral parent training, teacher training, or a combination, in children with ADHD under 18 years. Outcomes were symptom counts of total ADHD, inattention, and hyperactivity-impulsivity and behavioral problems. The dosage of techniques was extracted from the intervention manuals. Metaregression was used to assess which techniques and intervention characteristics (setting, delivery method, duration, and home-school collaboration) were associated with intervention effectiveness. RESULTS: Higher dosage of psycho-education for parents was associated with smaller effects on behavioral problems and, only in case of parent training, also with smaller effects on ADHD symptoms. Higher dosage of teaching parents/teachers to use negative consequences was associated with larger effects on behavioral problems. Individual training compared with group training was associated with larger effects on ADHD and hyperactivity-impulsivity symptoms. CONCLUSIONS: This study provides first insights into the specific techniques that are essential in behavioral parent and teacher training programs for children with ADHD. This knowledge can eventually be used to improve and tailor interventions. ispartof: CHILD AND ADOLESCENT MENTAL HEALTH vol:28 issue:2 pages:258-268 ispartof: location:England status: published

OBJECTIVE: Behavioral parent training is an evidence-based intervention for children with attention-deficit/hyperactivity disorder (ADHD), but it is unknown which of its components are most effective. This meta-regression analysis investigated which specific behavioral techniques that parents learn in parent training are associated with effects on parental outcomes. METHOD: A search was performed for randomized controlled trials on parent training for children with ADHD, with positive parenting, negative parenting, parenting sense of competence, parent-child relationship quality, and parental mental health as outcome measures. After screening 23,026 publications, 29 studies contributing 138 effect sizes were included (N = 2,345). For each study, the dosage of 39 behavioral techniques was derived from intervention manuals, and meta-regression determined which techniques were related to outcomes. RESULTS: Parent training had robust small- to medium-sized positive effects on all parental outcomes relative to control conditions, both for unblinded and probably blinded measures. A higher dosage of techniques focusing on the manipulation of antecedents of behavior was associated with better outcomes on parenting sense of competence and parental mental health, and a higher dosage of techniques focusing on reinforcement of desired behaviors was related to larger decreases in negative parenting. Higher dosages of psychoeducation were negatively related to parental outcomes. CONCLUSION: Although techniques were not investigated in isolation, the results suggested that manipulation of antecedents of behavior and reinforcement techniques are key components of parent training for children with ADHD in relation to parental outcomes. These exploratory findings may help to strengthen and tailor parent training interventions for children with ADHD. ispartof: Journal Of The American Academy Of Child And Adolescent Psychiatry vol:61 issue:4 pages:478-494 ispartof: location:United States status: Published online

Behavioral teacher training is an effective intervention for children with attention-deficit/hyperactivity disorder (ADHD). Intervention effectiveness may be enhanced by including intervention components that carry the strongest evidence for their effectiveness. A previous article of this group showed that both antecedent- (i.e., stimulus-control) and consequent-based (i.e., contingency management) techniques were highly effective in reducing daily teacher-rated, individually selected problem behaviors in a specific situation of the child. Effects were observed up to three months post intervention. Here, we tested whether effects were also present in teacher-rated and masked DSM-based assessments that comprise the full range of ADHD and oppositional defiant disorder (ODD) symptoms, as well as on teacher-rated impairment. Teachers of 90 children with (subthreshold) ADHD (6-12 years) were randomly assigned to one of three conditions: a short (two sessions), individualized intervention consisting of either a) antecedent-based techniques or b) consequent-based techniques; or c) waitlist. Multilevel analyses showed that both sets of techniques were effective in reducing teacher-rated ADHD symptoms and impairment immediately after the intervention and up to three months later, as compared to waitlist. Masked observations of ADHD behavior were in line with teacher ratings, with effects being most pronounced for inattention. No effects on teacher-rated or masked ODD behavior were found. This study showed that antecedent- and consequent-based techniques were effective in improving classroom ADHD symptoms and impairment. Long-term changes in teacher-rated ADHD are promising. These results extend previous findings and show the potential of short individually tailored interventions in classroom settings as treatment of ADHD symptoms. ispartof: Research on Child and Adolescent Psychopathology vol:50 issue:7 pages:1-14 ispartof: location:United States status: Published online

Behavioural parent training is an evidence-based intervention for children with attention-deficit/hyperactivity disorder (ADHD), but little is known about the extent to which initial benefits are maintained. This meta-analytic review investigated longer-term (i.e., more than two months post-intervention) child and parental outcomes of behavioural parent training for children with ADHD. We searched for randomized controlled trials and examined ADHD symptoms, behavioural problems, positive parenting, negative parenting, parenting sense of competence, parent-child relationship quality, and parental mental health as outcomes. We included 27 studies (31 interventions; 217 effect sizes), used multilevel random-effects meta-analyses for between- and within-group comparisons (pre-intervention to follow-up and post-intervention to follow-up), and explored twelve predictors of change. Between pre-intervention and follow-up (M = 5.3 months), we found significant small-to-moderate between-group effects of the intervention on ADHD symptoms, behavioural problems, positive parenting, parenting sense of competence and parent-child relationship quality. Within-group findings show sustained improvements in the intervention conditions for all outcome domains. There were few significant changes from post-intervention to follow-up. Additionally, the large majority of the individual effect sizes indicated sustained outcomes from post-intervention to follow-up. There were seven significant predictors of change in child outcomes, including stronger reductions in ADHD symptoms of girls and behaviour problems of younger children. In contrast with some meta-analyses on short-term effects, we found no differences between masked and unmasked outcomes on ADHD symptoms at follow-up. We conclude that behavioural parent training has longer-term benefits for children’s ADHD symptoms and behavioural problems, and for positive parenting behaviours, parenting sense of competence and quality of the parent-child relationship.

Behavioral parent training is an evidence-based intervention for children with attention-deficit/hyperactivity disorder (ADHD), but knowledge on the differential effects of behavioral techniques for specific subgroups of children is very limited. Attachment representations of children with ADHD may affect how receptive children are to changes in parenting. In this study, we investigated whether specific behavioral techniques were more or less effective for children with ADHD in relation to their attachment representations. We included parents of 74 children with ADHD (4–11 years, M = 8.15) who took part in a larger randomized controlled microtrial in which they were randomized to a two session training in antecedent-based techniques (i.e., stimulus control techniques: rules, instructions; n = 26), a two session training in consequent-based techniques (i.e., contingency management techniques: praise, rewards, ignoring; n = 25) or a waitlist control condition (n = 23). We examined whether attachment representation moderated the effectiveness of a) training versus waitlist, and b) antecedent- versus consequent-based techniques. Attachment representations were measured with a story stem task, the intervention outcome was daily parent-rated problem behaviors of the children. Attachment representation did not moderate the effects of the training compared to the waitlist. However, compared to antecedent-based techniques, consequent-based techniques were less effective for more securely and less disorganized attached children, and particularly effective for more disorganized attached children. This was the first study examining attachment as a moderator of behavioral techniques for ADHD. If replicated, the findings of this study can be used for treatment development and tailoring.

Behavioral parent training (BPT) is an evidence-based treatment for children with attention-deficit/hyperactivity disorder (ADHD). Stimulus control techniques (antecedent-based techniques, e.g., clear rules, instructions) and contingency management techniques (consequent-based techniques, e.g., praise, ignore) are the most common ones that are being taught to parents in BPT. However, research into the additive effects of these techniques is scarce. In this replicated single-case experimental ABC phase design, including six children on stable medication for ADHD (8-11 years) and their parents, the added efficacy of consequent-based techniques on top of antecedent-based techniques was evaluated. After a baseline period (phase A), we randomized the commencement time of two sessions parent training in antecedent-based techniques and two sessions parent training in consequent-based techniques for each child. Children's behaviors were assessed by daily parent ratings of selected problem behaviors and an overall behavior rating. Although visual inspection showed that behavior improved for most children in both phases, randomization tests did not demonstrate the added efficacy of the consequent-based techniques on top of the antecedent-based techniques. Limitations of the study and recommendations for future single-case experiments in this population are discussed. ispartof: BEHAVIOR MODIFICATION ispartof: location:United States status: Published online

Behavioral parent training (BPT) as treatment for children with ADHD has been found effective in numerous studies. There is little knowledge about the most effective components of these programs, and which components are most effective for whom. Insights into these matters could contribute to more personalized treatment. Therefore, the aim of this thesis was to examine which components of BPT for ADHD drive intervention effects, and for whom.Techniques focusing on the manipulation of antecedents of behavior (antecedent-based techniques) and contingency management techniques (consequent-based techniques) were found to be key components of BPT for children with ADHD in two meta-regression analyses. To examine the components in isolation, a microtrial was conducted with two sessions of BPT in antecedent-based techniques, two sessions in consequent-based techniques, and a waitlist control-condition. Both types of techniques improved problem behaviors. Antecedent-based techniques appeared to be especially important to target inattention. In a series of replicated single-case experiments no added efficacy of consequent-based techniques on top of antecedent-based techniques, and no effects of antecedent-based techniques alone was demonstrated. Differences between the two experimental studies may be the result of the different designs, timing of the treatment or medication-use. To explore attachment in relation to ADHD, this thesis examined two samples of children with and without ADHD, using two different methods to measure attachment. Children with ADHD had less secure, and more ambivalent and disorganized attachment representations relative to their typically developing peers when using a story-stem-task, but these differences were not found using self-report questionnaires. Lastly, findings in this thesis tentatively suggest that techniques are differentially effective based on attachment representation.

OBJECTIVE: Behavioral parent training (BPT) is an evidence-based intervention for children with attention-deficit/hyperactivity disorder (ADHD), but little is known about the effects of separate techniques parents learn in BPT. METHOD: In a three-armed randomized controlled microtrial including parents of 92 children (4-12 years) with ADHD, we examined the efficacy of two sessions parent training involving either stimulus control techniques (antecedent-based condition (AC)) or contingency management techniques (consequent-based condition (CC)), compared to a waitlist. Primary outcome was daily parent-rated problem behaviors, secondary outcomes were parent-rated symptoms of ADHD and oppositional defiant disorder (ODD), and mental health-care consumption. Measures were completed at baseline (T0), immediately after the training (T1), at two weeks (T2) and three months (T3) follow-up. We also explored whether child and parent characteristics moderated treatment effects. RESULTS: Compared to the waitlist, in the AC, daily rated problem behaviors improved at T1 (d= .56) and T2 (d= .65); in the CC, these behaviors only improved at T2 (d= .53). Daily rated problem behaviors within both conditions remained stable between T2 and T3. In the AC compared to the other conditions, inattention symptoms decreased at T1 and T2. For both active conditions compared to waitlist, hyperactivity-impulsivity symptoms decreased only at T2 and ODD symptoms did not decrease. No moderators were identified. Mental health-care consumption after training was low and did not differ between the active conditions. CONCLUSIONS: Brief training of parents in antecedent- or consequent-based techniques improves problem behaviors of children with ADHD. Antecedent-based techniques appear to be especially important to target inattention. ispartof: Journal Of Clinical Child And Adolescent Psychology vol:50 issue:6 pages:888-903 ispartof: location:England status: Published online

Attention-Deficit/Hyperactivity Disorder (ADHD) in children is associated with several adverse family characteristics, such as higher parenting stress, more conflicted parent-child relationships, lower parental competence, and higher levels of parental psychopathology. Hence, children with ADHD more often grow up under suboptimal circumstances, which may impact the development of their attachment representations. Here, we investigated whether children with ADHD have more insecure and disorganized attachment representations than their typically developing peers, and which factors could explain this association. We included 104 children between 4 and 11 years old, 74 with ADHD (without Conduct Disorder) and 30 typically developing control children. Children completed a state-of-the-art story stem task to assess their attachment representation, and we measured parents' expressed emotion (as an index of parent-child relationship quality), parents' perceived sense of competence, parental education levels, and parent-rated ODD symptoms of the child. We found that, after controlling for multiple comparisons, children with ADHD had less secure and more ambivalent and disorganized attachment representations relative to their typically developing peers. These group differences were independent of comorbid ODD and parental education levels. There were no group differences on avoidant attachment representations. Explorative analyses within the ADHD group showed that attachment representations were not related to parent-child relationship quality, perceived parenting competence, parental education levels, and comorbid ODD symptoms. We conclude that children with ADHD disproportionately often have attachment problems. Although this conclusion is important, treatment implications of this co-occurrence are yet unclear as research on ADHD and attachment is still in its infancy. ispartof: Brain Sciences vol:11 issue:11 pages:1-13 ispartof: location:Switzerland status: published

Objective: Behavioral teacher training is the most effective classroom-based intervention for children with attention-deficit/hyperactivity disorder (ADHD). However, it is currently unknown which components of this intervention add to its effectiveness and for whom these are effective.Method: In this microtrial, teachers of 90 children with impairing levels of ADHD symptoms (6-12 years) were randomly assigned to one of three conditions: a short (2 sessions), individualized intervention consisting of either (A) antecedent-based techniques (stimulus control), (B) consequent-based techniques (contingency management) or (C) waitlist. Primary outcome was the average of five daily assessments of four individualized problem behaviors, assessed pre and post intervention and three months later. Moderation analyses were conducted to generate hypotheses on child, teacher and classroom factors that may contribute to technique effectiveness.Results: Multilevel analyses showed that both antecedent- and consequent-based techniques were equally and highly effective in reducing problem behaviors compared to the control condition (Cohen's d =.9); effects remained stable up to three months later. Child's age and class size were moderators of technique effectiveness. For younger children, consequent-based techniques were more effective than antecedent-based techniques, whereas for older children the effect was in the opposite direction. Further, beneficial effects of antecedent-based techniques increased when the number of students per class decreased, whilst effectiveness of consequent-based techniques did not depend on class size.Conclusions: This study shows that both antecedent- and consequent-based techniques are highly effective in reducing problem behavior of children with ADHD. Interventions may be adapted to the child's age and class size. ispartof: Journal Of Clinical Child And Adolescent Psychology vol:50 issue:6 pages:1-17 ispartof: location:England status: Published online

IntroductionBehavioural parent training (BPT) is a well-established treatment for children with attention-deficit/hyperactivity disorder (ADHD). BPT is based on the hypothesis that improvements in parenting are mediators of improvements in children’s behaviours. However, meta-analyses show considerate heterogeneity in effects of BPT on child outcomes, and meta-analyses on parenting outcomes are scarce. Also, few studies have investigated parenting factors as mediators of child outcomes. This study aims to examine the effects and moderators of BPT on parenting outcomes and whether improvements in parenting mediate amelioration of behaviour and impairment in children with ADHD.Methods and analysesWe will conduct an individual participant data meta-analysis (IPDMA), making use of individual data of existing trials, and giving the opportunity for highly powered moderator analyses. This IPDMA will be performed by the Psychosocial ADHD INTervention (PAINT) collaboration. We will include randomised controlled trials of BPT, for individuals with ADHD below 18 years old. Systematic searches have been performed to locate relevant papers. Authors are currently contacted to share their data with the PAINT-IPDMA project. We will examine effects of BPT on parenting outcomes (eg, positive and negative parenting, management of affect, perceived parenting competence, parenting stress), moderators of these effects (eg, parental depression, parenting stress, severity of the child’s ADHD symptoms) and subsequently perform mediation analyses where parenting outcomes are modelled as mediators of child outcomes (eg, symptoms and severity of ADHD, comorbid psychopathology and impairment).Ethics and disseminationWe will include data from randomised control trials for which ethical approval has been received and consent forms have been signed. Deidentified data will be provided by the original investigators. We aim to disseminate our findings through peer-reviewed scientific journals, presentations at (inter)national scientific meetings, newsletters, the website of our project and the Dutch academic workspace ADHD.PROSPERO registration numberCRD42017069877.
