The primary objective of this study is to test the efficacy of Internet-delivered cognitive behavior therapy (ICBT) for adolescents (12 - 17 years) with OCD. We aim to conduct a randomized controlled study with N = 66 participants. Participants will be randomly assigned to ICBT or a wait list condition, either lasting 12 weeks. The primary outcome measure is the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Study participants will be followed up 3 and 12 months after treatment. ICBT is expected to yield significantly better symptom reduction than the wait list condition.
The effect of Internet-delivered Cognitive Behavior Therapy (ICBT) on adolescents (12 to 17 years) with Obsessive-Compulsive Disorder is studied. Participants are randomized to either ICBT or a no-treatment condition. We expect ICBT to be superior over the no-treatment condition.
