Sequential treatment of ADHD in mother and child (AIMAC study): importance of the treatment phases for intervention success in a randomized trial

Background: The efficacy of parent-child training (PCT) regarding child symptoms may be reduced if the mother has attention-deficit/hyperactivity disorder (ADHD). The AIMAC study (ADHD in Mothers and Children) aimed to compensate for the deteriorating effect of parental psychopathology by treating the mother (Step 1) before the beginning of PCT (Step 2). This secondary analysis was particularly concerned with the additional effect of the Step 2 PCT on child symptoms after the Step 1 treatment. Methods: The analysis included 143 mothers and children (aged 6–12 years) both diagnosed with ADHD. The study design was a two-stage, two-arm parallel group trial (Step 1 treatment group [TG]: intensive treatment of the mother including psychotherapy and pharmacotherapy; Step 1 control group [CG]: supportive counseling only for mother; Step 2 TG and CG: PCT). Single- and multi-group analyses with piecewise linear latent growth curve models were applied to test for the effects of group and phase. Child symptoms (e.g., ADHD symptoms, disruptive behavior) were rated by three informants (blinded clinician, mother, teacher). Results: Children in the TG showed a stronger improvement of their disruptive behavior as rated by mothers than those in the CG during Step 1 (Step 1: TG vs. CG). In the CG, according to reports of the blinded clinician and the mother, the reduction of children’s disruptive behavior was stronger during Step 2 than during Step 1 (CG: Step 1 vs. Step 2). In the TG, improvement of child outcome did not differ across treatment steps (TG: Step 1 vs. Step 2). Conclusions: Intensive treatment of the mother including pharmacotherapy and psychotherapy may have small positive effects on the child’s disruptive behavior. PCT may be a valid treatment option for children with ADHD regarding disruptive behavior, even if mothers are not intensively treated beforehand. Trial registration: ISRCTN registry ISRCTN73911400.

Child-based treatment of oppositional defiant disorder: mediating effects on parental depression, anxiety and stress

Previous research has shown that child-oppositional defiant disorder (ODD) and conduct disorders (CD) are associated with parental symptoms of depression, anxiety and/or stress, probably in a bidirectional relationship with mutual influences. It is, therefore, reasonable to assume that in child-centered treatment, a decrease in child-oppositional behavior problems constitutes (at least in part) a mechanism of change for a subsequent reduction in parental psychopathology. The aim of the present study (Clinical trials.gov Identifier: NCT01406067) was to examine whether the reduction in ODD symptoms due to child-based cognitive behavioral treatment (CBT) led to a reduction in parental depression, anxiety and stress. Eighty-one boys (age 6-12years) with a diagnosis of ODD/CD were randomized either to a cognitive behavioral intervention group or an educational play group (acting as control group). Mediation analyses were conducted using path analysis. The stronger reduction in child ODD symptoms in the CBT group compared to the control group led to a decrease in parental depression and stress, as indicated by significant indirect effects (ab=0.07 and ab=0.08, p<0.05). The proposed model for mechanisms of change was, therefore, confirmed for two of the three outcome parameters. Parental psychopathology and stress can be modified by child-centered CBT. The preceding reduction in ODD symptoms acts as a mediator for at least some of the changes in parental depression and stress. However, due to some limitations of the study, other possible explanations for the results found cannot be completely ruled out and are, therefore, discussed

Social skills training and play group intervention for children with oppositional-defiant disorders/conduct disorder: Mediating mechanisms in a head-to-head comparison

Objective: Social-cognitive information processing, social skills, and social interactions are problem-maintaining variables for aggressive behavior in children. We hypothesized that these factors may be possible mediators of the mechanism of change in the child-centered treatment of conduct disorders (CDs). The aim of the present study (Clinical trials.gov Identifier: NCT01406067) was to examine putative mechanisms of change for the decrease in oppositional-defiant behavior resulting from child-centered treatment of patients with oppositional-defiant disorder (ODD) or CD. Method: 91 children (age 6-12 years) with ODD/CD were randomized to receive either social skills training or to a resource activating play group. Mediator analyses were conducted using path analyses. Results: The assumed mediating effects were not significant. However, alternative models with the putative mediators and outcome in reversed positions showed significant indirect effects of the oppositional-defiant symptoms as mediator for the decrease of disturbance of social-information processing, social skills, and social interactions. Conclusions: The proposed model for mechanisms of change could not be confirmed, with the results pointing to a reversed causality. Variables other than those hypothesized must be responsible for mediating the effects of the intervention on child oppositional-defiant behavior. Possible mechanisms of change were discussed

Behavioral and Nondirective Guided Self-Help for Parents of Children with Externalizing Behavior: Mediating Mechanisms in a Head-To-Head Comparison

Parent training (PT) delivered as a guided self-help intervention may be a cost- and time-effective intervention in the treatment of children with externalizing disorders. In face-to-face PT, parenting strategies have repeatedly been identified as mediating mechanisms for the decrease of children's problem behavior. Few studies have examined possible mediating effects in guided self-help interventions for parents. The present study aimed to investigate possible mediating variables of a behaviorally oriented guided self-help program for parents of children with externalizing problems compared to a nondirective intervention in a clinical sample. A sample of 110 parents of children with externalizing disorders (80 % boys) were randomized to either a behaviorally oriented or a nondirective guided self-help program. Four putative mediating variables were examined simultaneously in a multiple mediation model using structural equation modelling. The outcomes were child symptoms of ADHD and ODD as well as child externalizing problems, assessed at posttreatment. Analyses showed a significant indirect effect for dysfunctional parental attributions in favor of the group receiving the behavioral program, and significant effects of the behavioral program on positive and negative parenting and parental self-efficacy, compared to the nondirective intervention. Our results indicate that a decrease of dysfunctional parental attributions leads to a decrease of child externalizing problems when parents take part in a behaviorally oriented guided self-help program. However, none of the putative mediating variables could explain the decrease in child externalizing behavior problems in the nondirective group. A change in dysfunctional parental attributions should be considered as a possible mediator in the context of PT

Affective dysregulation in childhood - optimizing prevention and treatment: protocol of three randomized controlled trials in the ADOPT study

BACKGROUND: The terms affective dysregulation (AD) and irritability describe transdiagnostic dimensions and are characterized by an excessive reactivity to negative emotional stimuli with an affective (anger) and a behavioral component (aggression). Due to early onset, high prevalence and persistence, as well as developmental comorbidity, AD in childhood is one of the most psychosocially impairing and cost-intensive mental health conditions. AD is especially prevalent in children in the youth welfare service. Despite continuous research, there remains a substantial need for diagnostic approaches and optimization of individualized treatment strategies in order to improve outcomes and reduce the subjective and economic burden. METHODS: The ADOPT (Affective Dysregulation - Optimizing Prevention and Treatment) Consortium integrates internationally established, highly experienced and interdisciplinary research groups. The work program encompasses (a) epidemiology, including prevalence of symptoms and disorders, (b) development and evaluation of screening and assessment tools, (c) stepped care approaches for clinically useful personalized medicine, (d) evaluation of an easily accessible and cost-effective online intervention as indicated prevention (treatment effects, moderation/mediation analysis), and (e) evaluation of an intensive personalized modular outpatient treatment in a cohort of children with AD who live with their parents and in a cohort of children with AD who live in out-of-home care (treatment effects, moderation/mediation analysis). DISCUSSION: The results will lead to significant recommendations for improving treatment within routine clinical care in two cohorts of children with AD and coexisting conditions, especially oppositional-defiant disorder, conduct disorder and disruptive mood dysregulation disorder.

Process Mechanisms in Behavioral Versus Nondirective Guided Self-help for Parents of Children with Externalizing Behavior

The study examined potential mediating effects of therapist behaviors in the per-protocol sample (n = 108) of a randomized controlled trial comparing a behavioral and a nondirective guided self-help intervention for parents of children with externalizing disorders (4-11 years). Additionally, from an exploratory perspective, we analyzed a sequential model with parental adherence as second mediator following therapist behavior. Outcomes were child symptom severity of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder rated by blinded clinicians, and parent-rated child functional impairment. We found a significant indirect effect on the reduction of ADHD and functional impairment through emotion- and relationship-focused therapist behavior in the nondirective intervention. Additionally, we found limited support for an extended sequential mediation effect through therapist behavior and parental adherence in the models for these outcomes. The study proposes potential mediating mechanisms unique to the nondirective intervention and complements previous findings on mediator processes in favor of the behavioral group.

Effects of Computer-Assisted Social Skills Training in Children With Disruptive Behavior Disorders: A Randomized Controlled Trial

Objective: Computer-assisted child-focused interventions are expected to improve efficiency and personalization of therapist-led treatments for children and adolescents. However, therapist-led, outpatient interventions using computer assistance are lacking for children with oppositional defiant disorder (ODD) or conduct disorder (CD). The present randomized controlled trial examined the efficacy of individualized computer-assisted social skills training for children with aggressive behavior compared to a resource activation intervention. Method: A total of 100 children aged 6-12 years with a diagnosis of ODD/CD and peer-related aggression were randomly (1:1) assigned to either individually delivered computer-assisted social skills training (ScouT) or an individually delivered supportive resource activation treatment (STARK). The primary outcome was parent-rated peer-related aggression, assessed with the respective scale of the Questionnaire for Aggressive Behavior of Children (FAVK) and measured at pre-assessment and after the 16-week intervention (post-assessment). Further parent-, self-, teacher- and/or clinicianrated outcomes included ODD and CD symptoms, a wide range of behavioral and emotional symptoms, callous-unemotional traits, functional impairment, and quality of life. Results: After correcting for multiple testing, analyses of covariance comparing the efficacy of ScouT to the efficacy of STARK yielded small to moderate treatment effects in favor of the ScouT condition regarding parent-rated peer-related aggression (primary outcome; d = -0.64, 95% CI = -1.05, -0.24), parent-rated callous and uncaring traits, and parent-rated quality of life. However, the analyses did not reveal any significant effects for self- or teacher-rated peer-related aggression assessed with the respective scale of the FAVK (self-report: d = -0.21, 95% CI = -0.69, 0.29; teacher rating: d = -0.17, 95% CI = -0.56, 0.22). Moreover, after controlling for multiple comparisons, no significant effects emerged for the following: parent-, self-, and teacher-rated adult-related aggression; parent-, self-, teacher-, and clinician-rated ODD and CD symptoms; parent-, self-, and teacher-rated emotional and behavioral symptoms; and parent-rated functional impairment. Conclusion: According to parent ratings, school-age children with disruptive behavior disorders and peer-related aggression seem to benefit more from individualized, computer-assisted social skills training than from resource activation treatment. However, this conclusion is limited by the missing effects on the clinician-, self-, and teacher-rated measures.

Behavioral Versus Nonbehavioral Guided Self-Help for Parents of Children With Externalizing Disorders in a Randomized Controlled Trial

Self-help interventions for parents, which have a behavioral basis, are considered to be an effective treatment option for children with externalizing disorders. Nonbehavioral approaches are widely used but have little empirical evidence. The main objective of this trial was to compare the efficacy of a behavioral and a nonbehavioral guided self-help program for parents. Families of children (aged 4-11 years) diagnosed with attention-deficit/hyperactivity disorder (ADHD) or oppositional defiant disorder (ODD) were randomized to either a behavioral or a nonbehavioral guided self-help program including 8 parenting booklets and 10 counseling telephone calls. The analyses considered the ratings of 5 informants: blinded clinician, therapist, participant, (her or his) partner, and teacher. Of the 149 families randomized to treatment (intention-to-treat sample [ITT]), 110 parents completed the intervention (per-protocol sample [PP]). For the 4 primary outcome measures (blinded clinician- and participant-rated ADHD and ODD) at post assessment, the analysis revealed a treatment advantage for the behavioral group in blinded clinician-rated ODD symptoms (ITT: d = 0.37; PP: d = 0.35). Further treatment differences, all in favor of the behavioral group (ITT and PP), were detected in therapist ratings (i.e., ODD) and participant ratings (e.g., parental self-efficacy [only PP], negative parenting behavior, parental stress). In both samples, no differences were found at post-assessment for ratings of the partner and the teacher, or at the 12-month follow-up (only participant ratings available). Behavioral guided self-help shows some treatment advantage in the short term. No superiority over nonbehavioral therapy was detected 12 months after treatment termination
