Cognitive behavior therapy for comorbid obsessive-compulsive disorder in high-functioning autism spectrum disorders: a randomized controlled trial.
BACKGROUND High rates of anxiety disorders , particularly obsessive compulsive disorder ( OCD ) are reported in people with Autism spectrum disorders ( ASD ) .  Group cognitive behavioral treatment ( CBT ) has been found effective for anxiety in young people with ASD but not been OCD specific . One uncontrolled pilot study of individual CBT for OCD for adults with ASD showed good treatment efficacy . METHODS Forty-six adolescents and adults ( mean age 26.9 years , 35 Males ) with ASD and comorbid OCD were r and omized to CBT for OCD or anxiety management ( AM ) , a plausible control treatment . Treatments were matched in duration ( mean of 17.4 sessions CBT ; 14.4 sessions AM ) , the Yale-Brown Obsessive Compulsive Severity Scale ( YBOCS ) as primary outcome measure and evaluations blind to treatment group . Treatment response was defined as > 25 % reduction in YBOCS total severity scores . RESULTS Both treatments produced a significant reduction in OCD symptoms , within-group effect sizes of 1.01 CBT group and 0.6 for the AM group . There were no statistically significant differences between the two groups at end of treatment , although more responders in the CBT group ( 45 versus 20 % ) . Effect sizes for self-rated improvement were small ( 0.33 CBT group ; -0.05 AM group ) . Mild symptom severity was associated with improvement in the AM but not the CBT group . Family/carer factors were important for both groups , in that increased family accommodation was associated with poorer outcome . CONCLUSIONS Evidence -based psychological interventions , both AM and CBT , were effective in treating comorbid OCD in young people and adults with ASD
