About this study
Official title: Taking Psychiatry Online: Developing a Platform to Provide Internet-Delivered Cognitive-Behavior Therapy and Testing It in Obsessive-Compulsive Disorder
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.
Read the detailed 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:
- Develop a digital platform for the treatment of mental disorders using therapist-guided iCBT;
- Assess the feasibility, acceptability, and potential effects of therapist-guided iCBT for adult obsessive-compulsive disorder (OCD) using the platform developed in Objective 1.

What is being measured
The primary outcome is the main question the study is designed to answer.
Feasibility (recruitment and retention rates and therapist burden)
The investigators will assess feasibility by recording recruitment rates, retention rates, and therapist burden (time spent by the therapist sending emails, reviewing materials, etc.).
Measured: From enrollment to the end of treatment at 12 weeks
