Former Bergen 4-Day Treatment Patient
“I’m a doctor and I have suffered from OCD since I was a kid. Four days with the OCD team in 2014 changed my life. Since then I have been able to complete my training as a cardiologist, and I have followed their research and been part of their Scientific Advisory Board. All I can say is: If you suffer from OCD and get the opportunity be a part of the Bergen 4-day treatment: Take it!”

Information About Bergen 4 Day Treatment
What is B4DT
The Bergen 4-day treatment (B4DT) is a concentrated exposure treatment (cET) where the patient receives individually tailored CBT delivered during four consecutive days. B4DT can be categorized as an individual treatment delivered in a group setting, since the treatment is delivered in groups with 3 to 6 patients with a therapist-patient ratio of 1:1. The B4DT has proven highly effective for treating obsessive-compulsive disorder, with almost no drop-out rates and almost 70% of patients reported as recovered at 12-month follow-up. A follow-up study demonstrated that the treatment outcome was stable 4 years after completing treatment.
The B4DT approach has received tremendous attention around the world. For example, in October of 2018, Drs. Bjarne Hansen and Gerd Kvale (the developers of B4DT) were selected by Time magazine as two of “The Health Care 50: Fifty People Transforming Health Care in 2018.” The approach builds on four decades of empirical research and theories about the most effective approach to OCD treatment. The innovation and strength of the work is how it combines the most effective elements of proven treatment into one of the most profound, rapid, and robust treatment approaches that we have seen in recent years. Thus, this approach provides for a truly transformative treatment and it has the potential to meaningfully improve health care delivery in the U.S.
Over 16,000 patients with OCD have been effectively treated with the B4DT in Norway during the last decade. Furthermore, over 1000 patients OCD patients have completed the B4DT outside Norway – in 12 countries: Iceland, Singapore, Denmark, Sweden, Finland, Germany, the United States, Ecuador, Australia, Brazil, Argentina, and New Zealand. Over 50 research studies have been conducted on this treatment approach and all studies strongly support the effectiveness of this 4-day approach.
In addition to delivering the B4DT in Los Angeles, we actively collaborate with the original Bergen team in Norway to support the international dissemination and training of clinicians. In partnership with the Bergen team, we will offer B4DT training programs in North America and internationally for English-speaking clinicians in 2026.
In addition, teams from China, India, Belgium, Turkey, Colombia, Mexico, Chile, Indonesia, Cambodia, and Malaysia have signed up to be trained on the B4DT. The OCD & Anxiety Program of Southern is the only program that offers this treatment in the United States.
