Intensive treatment for OCD – B4DT

We are testing the non-inferiority, speed of recovery, and cost-effectiveness of Bergen 4-Day Treatment (B4DT) for obsessive compulsive disorder (OCD), compared to gold-standard CBT in a randomized controlled trial.

About gold standard CBT and the B4DT

Cognitive behavioral therapy (CBT) with exposure and response prevention (ERP) is an effective treatment for OCD and is recommended as a first-line intervention. However, the duration of CBT is typically 3-4 months, and around half of individuals who undergo CBT remain impaired even after treatment.

B4DT is a new concentrated treatment for OCD developed by Gerd Kvale and Bjarne Hansen from Bergen. In B4DT, patients receive ERP at a clinic during 4 consecutive days. The B4DT has shown to achieve remission in around 70% of patients when delivered in regular care in several uncontrolled treatment trials, and one randomized controlled trial (RCT) including a self-help group and a waitlist group.

However, it has yet to be directly compared to gold-standard CBT, and that is what we propose to do in this study.
