What this trial studies

This clinical trial evaluates the effects of mentalization-based group psychotherapy on patients diagnosed with anxiety and/or depression. A total of 100 participants will be recruited from community mental health services and randomized into two groups: one receiving standard acceptance and commitment therapy and the other receiving the new mentalization-based intervention. Assessments will be conducted at baseline and after three months to measure various psychological outcomes. The study aims to ensure participant safety and data integrity throughout the trial.

Why it matters

Potential benefit: If successful, this approach could provide a new therapeutic option for patients struggling with anxiety and depression.

How similar studies have gone: While similar approaches have been explored, this specific mentalization-based intervention is relatively novel in the context of anxiety and depression treatment.
