“…As is typical in treatment development research (Bagner, Rodriguez, Blake, & Rosa-Olivares, 2013;Chu, Colognori, Weissman, & Bannon, 2009), a sample of 6-10 adolescents (ages 12-17) as well as their parents or guardians was the projected sample size for the open trial. To be invited to a pre-treatment assessment, families were required to meet the following eligibility criteria: (a) adolescent had a lifetime history of ADHD or at least 4 symptoms endorsed by parent report on the Disruptive Behavior Disorders Rating Scale (Pelham et al, 1992), (b) adolescent displayed current subthreshold depressive symptoms as indicated by either parent-report or adolescent self-report (i.e., a T-score of 65 or greater on the Children's Depression Inventory-2 nd Edition; Kovacs, 2011), (c) families had received psychosocial/behavioral treatment for ADHD, and (d) the adolescent was currently enrolled in middle school or high school.…”
