Abstract
Background Gambling disorder (GD) has become a wide concern in Indonesia, as many negative consequences arise from this psychiatric condition. Prompt treatment with an appropriate method of delivery is required to achieve optimal outcomes in GD patients. This protocol paper outlines a study to determine the effectiveness, acceptability, and feasibility of internet-based cognitive behavioral therapy (iCBT) in treating GD in Indonesia. Methods This non-randomized pilot and feasibility study will recruit 20 people with GD. All participants will receive the iCBT intervention through self-learning videos and guided weekly group sessions. The effectiveness of the intervention will be assessed at baseline (week 0), post- treatment completion (week 10), and 6 weeks post-treatment (week 16). The outcomes measured will be the change in gambling symptoms, gambling urges, cognitive distortions, readiness to change, emotional problems, and quality of life of the participants. Discussion The feasibility of iCBT for GD patients in Indonesia will be assessed by this study. The study's results will give an indication of the acceptability of the intervention and the feasibility of a subsequent conclusive trial. The delivery of iCBT may help to address the issue of treatment access in an extensive geographical region and provide immediate implications as a treatment resource for GD in practice.
