Brief Summary

The purpose of this study is to investigate if therapist-guided internet-delivered cognitive behavioral therapy (ICBT) in a stepped-care approach is an effective and cost-effective treatment in reducing OCD symptoms for children and adolescents compared to gold standard treatment (face-to-face CBT).

Detailed Description

A randomized controlled non-inferiority trial comparing therapist-guided internet-delivered cognitive behavioral therapy (ICBT) in a stepped care model with face-to-face CBT for children and adolescents with obsessive-compulsive disorder (OCD).

Participants will be randomized to either stepped care ICBT or to gold standard face-to-face CBT. One group (stepped care) will be first offered ICBT for 16 weeks. Non-responders at the 3-month follow-up will receive additional face-to-face CBT. The other group (gold standard treatment) will be randomized directly to receive face-to-face CBT for 16 weeks. Non-responders will, as in the other group, receive additional face-to-face treatment after the 3-month follow-up. The primary endpoint will be at 6-month follow-up. Long-term effects are also investigated (1 year, 2 years and 5 years after treatment completion).

The primary objective is to evaluate whether ICBT in a stepped care approach will be non-inferior to gold standard treatment (face-to-face CBT) in reducing OCD symptoms, depression, impairment, sleep problems, health and functioning. The secondary objective is to a) carry out a full health economic evaluation and b) investigate if self-referred and referred participants differ regarding outcome in the two treatment groups.

The hypotheses are:

1. An ICBT stepped care approach will be non-inferior to gold standard treatment (face-to-face CBT) in reducing OCD symptoms.

2. The stepped care approach will be associated with lower costs, such as reduced therapist and administration times, service utilization, minimized work and school absence for families etc., compared to gold standard treatment.

3. Self-referred patients will benefit significantly better than referred patients regarding outcome in the ICBT group, but there will not be any difference in the face-to-face CBT group.
