What this trial studies

This trial investigates the effectiveness of online transdiagnostic cognitive behavior therapy (CBT) compared to standard care for adult primary care patients experiencing subsyndromal mental ill-health. 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 aims to determine if the online CBT can lead to greater symptomatic improvement and enhance quality of life for these patients. The trial addresses a significant gap in treatment options for individuals who do not meet the criteria for specific psychiatric disorders but still require mental health support.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with subsyndromal mental health issues related to anxiety, depression, or stress who can access the internet and read Swedish.

Not a fit: Patients with severe psychiatric disorders requiring specialized care or those currently undergoing psychological treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide accessible and effective mental health treatment for patients with mild symptoms, improving their overall well-being.

How similar studies have performed: While there is limited data on this specific approach, other studies have shown promise for online CBT in treating various mental health conditions.
