About

The goal of the study is to assess the feasibility, acceptability, and potential effects of therapist-guided internet-delivered cognitive-behavior therapy (iCBT) for adult obsessive-compulsive disorder, using a recently developed digital platform.

Full description

Although cognitive-behavior therapy (CBT) is a well-established first-line treatment for many mental disorders, very few patients receive it due to the shortage of trained professionals, the costs of face-to-face therapy, and geographic barriers. Therapist-guided internet-delivered CBT (iCBT) is a potential solution to this problem but is not generally available in our context.

The investigators plan to:

1. Develop a digital platform for the treatment of mental disorders using therapist-guided iCBT;
2. Assess the feasibility, acceptability, and potential effects of therapist-guided iCBT for adult obsessive-compulsive disorder (OCD) using the platform developed in Objective 1.
