The Bergen 4‐Day <scp>OCD</scp> Treatment: A Comprehensive Scoping Review of Evidence and Implementation

BACKGROUND: Obsessive-compulsive disorder (OCD) affects 1%-3% of the population, significantly impairing daily functioning and quality of life. Traditional treatments, including cognitive behavioral therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs), often face implementation challenges. AIM: This scoping review explores the efficacy and effectiveness of the Bergen 4-Day OCD Treatment (B4DT) across various populations and clinical settings. METHOD: A systematic search was conducted for studies published between 2005 and 2025, focusing on the B4DT's outcomes, patient satisfaction, and treatment acceptability. The PCC framework guided the development of the inclusion and exclusion criteria. RESULTS: Twelve studies met the inclusion criteria, demonstrating a reduction in OCD symptoms, high response and remission rates, and strong patient satisfaction. Long-term follow-up indicated durable treatment effects, with minimal relapse. CONCLUSION: The Bergen 4-Day Treatment is a viable frontline option for OCD management, warranting further research to optimize its implementation across diverse healthcare systems. Future studies should focus on enhancing patient adherence and expanding the treatment's applicability.
