What this trial studies

This clinical trial aims to investigate the impact of outdoor walking in different environments—urban versus natural—on depressive symptoms among college students. Participants will be randomly assigned to one of three groups: an urban walk, a nature walk, or an active nature walk with guided prompts for engagement. Each participant will walk for 30 minutes, twice a week, over three weeks, while completing questionnaires and participating in interviews to assess changes in depressive symptoms and other related factors. The study will evaluate whether structured engagement during nature walks enhances the benefits compared to unstructured walks.

Who should consider this trial

Good fit: Ideal candidates for this study are college students in Seattle aged over 18 who are experiencing depressive symptoms.

Not a fit: Patients currently receiving clinical psychiatric treatment or psychological counseling may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence that outdoor walking, particularly in natural settings, is an effective intervention for reducing depressive symptoms in college students.

How similar studies have performed: Other studies have shown positive outcomes with similar approaches, indicating that outdoor activities can improve mental health, though this specific comparison of environments is novel.
