The Effectiveness of Exposure and Response Prevention (ERP) for Obsessive-Compulsive Disorder (OCD): A Meta-Analysis of Randomized Controlled Trials
Abstract
Exposure and Response Prevention (ERP) is a first-line psychological treatment for Obsessive-Compulsive Disorder (OCD). This meta-analysis of randomized controlled trials (RCTs) evaluates the efficacy of ERP in reducing OCD symptoms and improving overall functioning in individuals with OCD. Through an exhaustive review of the literature, the meta-analysis synthesizes effect sizes from RCTs assessing the effectiveness of ERP compared to control conditions (e.g., waitlist, supportive therapy) in targeting core symptoms of OCD, including obsessions, compulsions, and related distress. Additionally, it examines potential moderators of treatment outcomes, such as treatment duration, therapist involvement, level of exposure, and participant characteristics (e.g., age, symptom severity), to better understand the factors influencing the effectiveness of ERP for OCD.
