What this trial studies

This study investigates two types of psychotherapy—supportive-expressive therapy and emotion-focused therapy—for individuals with major depressive disorder. A total of 124 patients will be randomized to receive 16 sessions of one of the therapies, with the aim of understanding how different mechanisms of change, such as insight and emotional processing, affect treatment outcomes. The study will utilize a variety of methods, including self-report questionnaires, hormonal and acoustic measures, cognitive tasks, and clinician interviews, to assess the effectiveness of each approach. The findings aim to enhance personalized treatment strategies based on patients' strengths and weaknesses in emotional processing and insight.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 who meet the diagnostic criteria for major depressive disorder and are fluent in Hebrew.

Not a fit: Patients with current suicidal risk, substance abuse disorders, or severe mental health conditions such as schizophrenia or bipolar disorder may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective, personalized psychotherapy treatments for patients with major depressive disorder.

How similar studies have performed: Previous studies have shown promise in using different psychotherapeutic approaches for depression, but this specific comparison of mechanisms is relatively novel.
