Summary

The aim of the study is to compare the efficacy of The OutSMARTers program- an ADHD skills training group program for children aged 9-12 to customized individual counseling provided by a professional, The Kid Counseling Program. Approximately 100 children will be randomly assigned to either intervention or a small wait-list group who will after a five-week-waiting period receive either intervention. Following the intervention, parents, children, and teachers will evaluate the effects on communication skills, well-being, and emotional regulation.

Detailed description

Attention-deficit hyperactivity disorder (ADHD) is an impairing neurodevelopmental disorder among children and adolescents that makes it difficult to cope with challenges of everyday life. Although various interventions have been developed to support parents of children with ADHD, few have been specifically designed for the children themselves, particularly interventions that focus directly on emotion regulation, problem-solving, communication and emotional well-being. The study is a randomized controlled trial (RCT) comparing the effectiveness of the OutSMARTers program, a skills-training group program based on cognitive- behavioral therapy (CBT) elements for children with ADHD. The program includes training in emotional regulation, social skills, self-control and problem-solving within a behavior modification framework. The comparison intervention, The Kid Counseling Program, consists of five sessions of individual counseling with similar content as in the OutSMARTers program, provided by a professional. The participants of this study will be approximately 100 children aged 9-12 that have been diagnosed with ADHD. Various methods will be used to assess outcomes, drawing on data from multiple sources through repeated measurements, including reports from parents, teachers, and the children themselves. The scientific goal of the study is to evaluate the efficacy of the OutSMARTers program, a group- based intervention delivered in 10 sessions over the course of 5 weeks, compared to brief individual counseling provided by a professional but not in a group of same-age peers. Positive changes in emotional regulation, communication skills, and well-being are expected in both groups. However, it is also possible that certain subgroups (e.g. children with or without comorbidities such as anxiety) may benefit more from one intervention over the other.

Interventions

Type	Name	Description
BEHAVIORAL	The OutSMARTers Program	An intervention specifically designed to improve common difficulties that children with ADHD wrestle with daily. The program consists of ten sessions (90 minutes each) conducted by two or three trainers working with a group of six children over the course of five weeks. The children attend four different stations during the intervention: the Emotion station and the Friendship station in sessions one through five, and the Stopping station and the Solution station in the remaining five. The program is fully manualized and was published in Icelandic in 2017 (Hannesdottir et al., 2017b). A small RCT pilot study of the OutSMARTers program delivered in a clinical setting showed beneficial effects on emotion regulation skills, social skills and a reduction in ADHD symptoms as rated by parents (Hannesdottir et al., 2017a).
BEHAVIORAL	The Kid Counseling Program	The Kid Counseling Program consists of five 50-minute individual counseling sessions, each delivered by a professional, and based on the book Learning to Slow Down and Pay Attention (Nadeau \& Dixon, 2004). The content closely mirrors that of the OutSMARTers program and shares the same goal; to improve common deficits that children with ADHD face. The key difference is that, unlike the OutSMARTers program, this intervention is individualized and does not include peer-based practice of the skills learned.
