Outcomes
Primary Outcome Measures
Changes in Y-BOCS from pre cET-treatment to post treatment/ waiting list/ self-help
Y-BOCS changes will for all conditions be calculated by two approaches which will be compared.
Changes i OCD diagnostic status (DSM-5) as measured by SCID
Secondary Outcome Measures
Well-being
The Warwick-Edinburgh Mental Well-being Scale (WEMWBS) will be administered to assess mental well-being. This scale has 14 items covering different aspects of mental health related to mental well-being.

Patient Health Questionnaire, (PHQ-9) is a 9-item self-report questionnaire measuring level of depressive symptoms. Items are scored on a scale from 0 (not at all) to 3 (nearly every day).
Insomnia
The Bergen Insomnia Scale (BIS) will be used to screen for sleep disturbances. The scale has six items covering different aspects of sleep disturbances the past 4 weeks

5. Study Description
Brief Summary
Obsessive Compulsive Disorder (OCD) often becomes chronic if not treated. Exposure and response prevention (ERP) is recommended psychological treatment. The OCD-team at Haukeland University hospital has developed a concentrated 4-day treatment format which has been evaluated as part of standard care. Next step in the methodological development is to conduct a randomized controlled trial where the 4-day format is compared to self-help and waiting list. The study will be conducted at Solvang DPS, Sørlandet Hospital. Participants (16 in each group) are ordinary patients (>18 yrs) entitled to care in the specialist health care.
