Evaluation of exposure with response-prevention for obsessive compulsive disorder in childhood and adolescence

The present study was undertaken to estimate the effect of exposure plus response-prevention (E/RP), delivered alone intensively over 5-weeks and without concomitant pharmacotherapy, for children and adolescents with OCD. Twenty children and adolescents with OCD, not receiving medication for this condition, were randomized to E/RP or a wait-list condition. Statistically and clinically significant symptomatic improvement was found in the E/RP group compared with controls, with improvement maintained at follow-up an average of 14 weeks later. Effect size in the main intention-to-treat analysis was 1.23 and in the secondary per protocol analysis was 1.64. This study lends further support to the view that E/RP is an effective treatment for childhood OCD
