Summary

Obsessive compulsive disorder (OCD) is one of the most disabling anxiety disorders occurring in about 2 out of a 100 adults. Untreated, OCD is a chronic and deteriorating condition, negatively impacting multiple areas of life with high personal and socioeconomic costs. In Denmark, anxiety disorders are estimated to be the most expensive of all psychiatric disorders and the most common reason for forced retirement.

In many countries including DK, CBT is the recommended, first-line treatment for OCD. All individuals who seek treatment in the Danish Regions are offered CBT. However, reviews show that up to 50% of patients either do not respond to CBT or terminate treatment prematurely. Despite this large number of non-responders, no significant progress for OCD treatment has been made since initial efficacy trials. Alternatives to CBT are needed .

Acceptance and Commitment therapy (ACT) is an innovative psychotherapy that can potentially help individuals with OCD who do not benefit from CBT. ACT targets the habitual thinking and behaviors that mark OCD by aiming to increase value-based behavior. OCD often co-occurs with depression and other anxiety disorders making treatment more difficult. ACT is a transdiagnostic treatment targeting symptoms that are common to anxiety and mood disorders. Preliminary findings indicate that ACT may be an effective treatment for OCD. However, these findings constitute a low level of evidence. Before ACT can be declared as an effective treatment for OCD, it needs to be demonstrated in randomize controlled trials, in which ACT is compared to legitimate, active treatments, such as CBT. This project will test the effectiveness of group-based ACT by comparing it to the first-line treatment, group-CBT in 180 participants referred for treatment in a specialized outpatient clinic at the Mental Health Services, Capital Region of Denmark. Furthermore, moderators and predictors of treatment response will be investigated.
