This investigation examined the effectiveness of a pilot, manualized 10-week intervention of family skills training for ADHD-related symptoms. The intervention combined behavioral parent training and child focused behavioral activation therapy. Participants were families with children ages 7-10 diagnosed with ADHD-Combined Type. This pilot investigation employed a single group, A-B research design comparing posttreatment behavioral symptoms to baseline functioning. Intervention effectiveness was analyzed using paired-samples t tests. Results indicated statistically significant improvements for behavioral symptoms from Time 1 to Time 2 with large main effects for the intervention. Further, intervention effects reduced symptoms below a level of clinical significance and greater than one standard deviation from baseline severity. Implications of combining behavioral activation training for children with ADHD and parent management training are discussed as well as the relevance of these results for improving the effectiveness and portability of empirically supported interventions.
