Treatment for obsessive-compulsive disorder (OCD) has drastically improved since behavioral models emerged over 60 years ago. Exposure and response prevention (ERP), the “gold standard” psychotherapy for OCD, is highly efficacious, yet a significant portion of patients either cannot access it or continue to experience residual symptoms following treatment. A growing body of research suggests other cognitive-behavioral approaches, particularly cognitive therapy, demonstrate comparable treatment effects to ERP. This brief review outlines research-supported cognitive-behavioral therapies for OCD including behavioral, cognitive, and “third wave” approaches such as metacognitive therapy and acceptance and commitment therapy. The theoretical foundations as well as an overview of research findings for each therapy are summarized. Recommendations for improving outcomes and access to treatment are also provided.
