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

11 de junho de 2026 atualizado por: 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.

Intervenção / Tratamento
Experimental: Bergen Four-Day Treatment
Outro: 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.

Descrição da medida
Prazo
Yale-Brown Obsessive-Compulsive Scale, Self-Report (Y-BOCS-SR)
Prazo: From pre-assessment to the end of follow-up approximately four to six months.
Changes in OCD symptoms will be assessed using the Yale-Brown Obsessive-Compulsive Scale, Self-Report (Y-BOCS-SR), a ten-item self-report measure with each item rated from 0 to 4. Total scores range from 0 to 40, with higher scores indicating more severe symptoms.
From pre-assessment to the end of follow-up approximately four to six months.
Obsessive-Compulsive Inventory - Revised (OCI-R)
Prazo: From pre-assessment to the end of follow-up approximately four to six months.
In addition to the Y-BOCS, changes in OCD symptoms will be assessed using the Obsessive-Compulsive Inventory - Revised (OCI-R), which consists of 18 items, each rated from 0 to 4, with total scores ranging from 0 to 72 points. Higher scores indicate more severe symptoms.
From pre-assessment to the end of follow-up approximately four to six months.
Client Satisfaction Questionnaire (CSQ-8)
Prazo: From pre-assessment to the end of follow-up approximately four to six months.
Patients will be asked about their satisfaction with the treatment using the Client Satisfaction Questionnaire (CSQ-8). The CSQ-8 consists of eight items, each rated on a scale from 1 to 4, with total scores ranging from 8 to 32. Higher scores indicate greater satisfaction with the treatment.
From pre-assessment to the end of follow-up approximately four to six months.
Credibility and Expectancy Questionnaire (CEQ)
Prazo: approximately four months
Patients' treatment expectations will be assessed using the Credibility and Expectancy Questionnaire (CEQ). The CEQ includes six items: four rated from 1 to 9 and two from 0% to 100%, with higher scores indicating greater expectations and confidence in the treatment.
approximately four months
Self-report for healthcare professionals (AIM, IAM, FIM)
Prazo: approximately four months
The acceptability, appropriateness, and feasibility of the treatment will be assessed among healthcare professionals using a combination of three subscales: the Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), and Feasibility of Intervention Measure (FIM). The AIM, IAM, and FIM each consist of four items rated on a five-point scale. Accordingly, the total score for each scale ranges from 4 to 20 points. The total 12-item score ranges from 12 to 60, with higher scores indicating greater overall treatment acceptability.

EuroQol 5-Dimension Questionnaire (EQ-5D)
Prazo: From pre-assessment to the end of follow-up approximately four to six months.
Quality of life will be assessed using the EuroQol 5-Dimension Questionnaire (EQ-5D), which consists of five items scored from 1 to 5, with total scores ranging from 5 to 25. Higher scores indicate lower perceived well-being. In addition, the EQ-5D includes a one-item scale for self-assessed well-being ranging from 0 to 100%. Higher percentages indicate higher perceived well-being.
From pre-assessment to the end of follow-up approximately four to six months.
