Group therapy for adolescents with attention-deficit/hyperactivity disorder: a randomized controlled trial.
OBJECTIVE To determine the efficacy of group cognitive-behavioral therapy ( CBT ) on adolescents with attention-deficit/hyperactivity disorder ( ADHD ) who were in pharmacological treatment but still had persistent symptoms . METHOD We conducted a multicenter , r and omized , rater-blinded , controlled trial between April 2012 and May 2014 in a cohort of 119 adolescents ( 15 - 21 years of age ) . Participants were r and omly assigned to 12 manualized group CBT sessions ( n = 45 ) or a waiting list control group ( n = 44 ) . Primary outcomes were assessed by a blinded evaluator ( ADHD Rating Scale [ ADHD-RS ] , Clinical Global Impression Scale for Severity [ CGI-S ] , Global Assessment of Functioning [ GAF ] ) before and after treatment , as well as by self-report and parent informant ratings . RESULTS Of the initial 119 participants enrolled , 89 completed treatment . A mixed-effects model analysis revealed that participants who were assigned to the group CBT sessions experienced significantly reduced ADHD symptoms compared to the control group ( ADHD-RS Adolescent : -7.46 , 95 % CI = -9.56 to -5.36 , p < .001 , d = 7.5 ; ADHD-RS Parents : -9.11 , 95 % CI = -11.48 to -6.75 , p < .001 , d = 8.38 ; CGI-S Self-Report : -0.68 , 95 % CI = -0.98 to -0.39 , p < .001 , d = 3.75 ; CGI-S Clinician : -0.79 , 95 % CI = -0.95 to -0.62 , p < .001 ; d = 7.71 ) . Functional impairment decreased significantly in the CBT group according to parents ( Weiss Functional Impairment Scale -4.02 , 95 % CI = -7.76 to -0.29 , p < .05 , d = 2.29 ) and according to the blinded evaluator ( GAF : -7.58 , 95 % CI = -9.1 to -6.05 , p < .001 , d = 7.51 ) . CONCLUSION Group CBT associated with pharmacological treatment is an efficacious intervention for reducing ADHD symptoms and functional impairment in adolescents .
