Exposure and Response Prevention (ERP) is considered the most effective treatment for OCD. ERP is a specific type of Cognitive Behavioral Therapy (CBT). Standard CBT consists of a number of evidence-based strategies designed to help specific types of symptoms. However, some of these strategies (e.g., relaxation or trying to rationalize/challenge intrusive fears) are not effective for OCD even though they may help with other problems. When you seek treatment, ensure your therapist has experience treating OCD with Exposure and Response Prevention (not just CBT).
