What this trial studies

This randomized controlled trial aims to evaluate the effectiveness of online transdiagnostic cognitive behavior therapy (CBT) compared to standard care for adult primary care patients with common mental disorders. Participants will be randomly assigned to receive either online CBT, which includes psychoeducation and therapeutic exercises delivered through a secure web platform, or care as usual. The study will assess symptomatic improvement, quality of life, and functional impairment, while also exploring treatment moderators and mediators. The goal is to provide evidence for a more accessible and resource-efficient treatment option for common mental disorders.

Why it matters

Potential benefit: If successful, this approach could significantly improve access to effective mental health treatment for patients in primary care settings.

How similar studies have gone: Other studies have shown promise for online CBT approaches, but this specific transdiagnostic method in a primary care context is still being evaluated.
