What this trial studies

This trial aims to evaluate the effectiveness of internet-based cognitive behavioral therapy (CBT) compared to synchronous CBT for treating adults with Gambling Disorder. A total of 150 participants will be randomly assigned to receive either 12 weeks of internet-based treatment called 'SpilleFri' or 18 weeks of individual synchronous CBT. The primary outcome will assess changes in gambling severity using self-reported measures at multiple time points, including a follow-up three months after treatment. The study seeks to determine if the internet-based approach is non-inferior to the traditional method in reducing gambling severity.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with Gambling Disorder who can read, write, and speak Danish and have access to the internet.

Not a fit: Patients with severe comorbid conditions, untreated psychiatric disorders, or those at risk of suicide may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more accessible and effective treatment option for individuals struggling with gambling disorder.

How similar studies have performed: Previous studies have shown promise in using internet-based therapies for various mental health conditions, suggesting potential success for this approach in treating gambling disorder.
