Bergen Four-Day Treatment (B4DT) for Obsessive-Compulsive Disorder

11. Juni 2026 aktualisiert von: Tampere University Hospital

The aim of this study is to expand access to Bergen Four-Day Treatment (B4DT) in Finland and to integrate it into psychiatric care pathways at Tampere University Hospital (TAYS). A Bergen team has been established within TAYS Psychiatry and has been trained in collaboration with the B4DT team from HUS and the Norwegian developers. The objective of this study is to enhance understanding of the model's adaptability to the Finnish healthcare system, evaluate healthcare professionals' attitudes toward the intervention, and assess treatment outcomes.

The aim is to recruit approximately 35 patients for the study. Patients will be recruited from a minimum of three groups (15 patients) and up to a maximum of six groups (35 patients). The criteria for admission to B4DT and for participation in the study are identical. The treatment and the study may include patients receiving specialized psychiatric care at Tampere University Hospital who have been diagnosed with obsessive-compulsive disorder and who experience significant impairment due to their symptoms. In addition, personnel from TAYS Psychiatry who recommend and refer patients for B4DT will be recruited for the study. The estimated number of participating staff members is approximately 30.

Intervention / Behandlung
Experimental: Bergen Four-Day Treatment
Sonstiges: Bergen Four-Day Treatment (B4DT)
The intervention starts with a pre-assessment, during which patients' motivation, expectations, and willingness to engage in exposure practice are assessed. After the pre-assessment, patients participate in a four-day intensive treatment period based on exposure and response prevention. The intensive phase is an individualized intervention delivered within a group framework. This phase is followed by a three-month period of independent practice, with a couple of appointments with the therapist. Changes in patients' symptoms, daily functioning, and well-being are assessed. In addition, healthcare professionals' attitudes toward the intervention will be examined.
