Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) experience significant academic impairment and multiple interventions have been developed to address common academic problems, such as difficulties with homework, organization, and planning skills. Given cost and resource constraints, research is needed on factors that mental health providers can use to select the most appropriate interventions. To date, there has been minimal research evaluating moderators of response to ADHD interventions. Further, many of the variables that have been studied do not have strong theoretical ties to the mechanisms of change invoked by the interventions. This study examined potential moderators of treatment response to two academic interventions for adolescents with ADHD: an organizational skills training intervention (HOPS) and a homework completion support intervention (CHIEF). Specifically, the study evaluated whether the cognitive skills known as executive functions (EF) moderate differential treatment response between the interventions. Results indicated that EF abilities were not consistently associated with differential treatment outcomes. Further, significant associations presented conflicting interpretations regarding which profiles of EF abilities were more responsive to HOPS in comparison to CHIEF.
