The article “Cognitive-Behavioral Therapy vs Risperidone for Augmenting Serotonin Reuptake Inhibitors in Obsessive-Compulsive Disorder: A Randomized Clinical Trial” by Simpson et al1 in this issue reports that exposure/ritual prevention (EX/RP) is without question more effective than risperidone or placebo in augmenting serotonin reuptake inhibitor (SRI) response in an 8-week randomized clinical trial with 100 participants. Simpson et al call for a change in practice, because augmentation for SRI nonresponders with atypical antipsychotics is recommended in the American Psychiatric Association guidelines.2 This is a well-controlled randomized clinical trial worthy of strong conclusions. Simpson et al have a track record of well-controlled combination studies in obsessive-compulsive disorder (OCD), and the conclusion that EX/RP should be considered first for SRI treatment augmentation is supported by the current data.
