What this trial studies

This clinical study aims to evaluate the effectiveness of schema therapy, a specific form of psychotherapy, for individuals suffering from chronic treatment resistant depression. Participants will be divided into two groups: one receiving schema therapy and the other receiving standard psychotherapeutic treatment. The study will assess depression outcomes at multiple time points, including 6, 12, and 24 months, while also exploring secondary outcomes related to functioning and personal recovery. Additionally, the research seeks to refine the understanding of chronic treatment resistant depression and its characteristics.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with chronic treatment resistant depression.

How similar studies have gone: While schema therapy has shown promise in treating various psychological conditions, this specific application for chronic treatment resistant depression is relatively novel.
