NCT ID NCT07644130
First seen Jun 25, 2026 · Last updated Sep 09, 2026 · Updated 3 times
Summary
This study tests a four-day intensive therapy called Bergen Four-Day Treatment (B4DT) for people with obsessive-compulsive disorder (OCD). About 35 patients will receive the therapy, which involves exposure and response prevention exercises over four days, followed by three months of independent practice. The goal is to see if this short, intensive approach can reduce OCD symptoms and be successfully integrated into Finland's healthcare system.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Bergen Four-Day Treatment (B4DT) - intensive exposure and response prevention therapy
- What this could lead to
- If successful, this could provide a shorter, more accessible treatment option for people with OCD, reducing symptoms and improving daily functioning.
- What could go wrong
- This is a small, early-stage study (65 participants) testing an existing therapy in a new setting. Results may not apply to all OCD patients, and the intensive format may not suit everyone.
