What this trial studies

This study investigates how client-therapist brain activity synchronizes during a psychosocial intervention aimed at alleviating depression symptoms. It compares two approaches: behavioral activation, a client-centered cognitive-behavioral therapy, and psychoeducation, which provides information on recovery strategies. Participants will attend a single session of one of these interventions while their brain activity is measured using EEG. They will also complete surveys about their mental and physical health before and after the session.

Who should consider this trial

Good fit: Ideal candidates are full-time students aged 18 to 30 experiencing mild to moderate depressive symptoms.

Not a fit: Patients with active suicidal ideation or a history of suicide attempts may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance therapeutic approaches for depression by understanding the neuroscience behind client-therapist interactions.

How similar studies have performed: While the specific approach of measuring brain synchronization during therapy is novel, related studies have shown promise in understanding therapeutic processes.
