Internet-based Cognitive Behavior Therapy (CBT) for Obsessive Compulsive Disorder (OCD)

Cognitive behavior therapy (CBT) is an effective treatment for obsessive compulsive disorder (OCD) but there is a lack of properly trained CBT therapists. One possible treatment alternative is Internet-based CBT (ICBT) with minimal therapist input. The aim of this study was therefore to evaluate ICBT for OCD.
