Benefits of Outdoor Walks in Reducing Depressive Symptoms

Summary

The goal of this clinical trial is to determine whether outdoor walking in different environments-urban or natural-can reduce depressive symptoms among college students. The study also tests whether providing prompts for active engagement during nature walks enhances the benefits compared to unstructured nature walks. Participants will be randomly assigned to one of three groups: (1) urban walk, (2) nature walk, or (3) active nature walk with guided interaction. Each participant will walk for 30 minutes, twice a week, for 3 weeks, complete questionnaires, and participate in interviews. Our primary outcome (PHQ-9) will be used to test the following two primary hypotheses: * Hypothesis 1: Participants in both nature walk conditions (combined) will show greater reductions in depressive symptoms (PHQ-9) than those in the urban walk group. * Hypothesis 2: Participants in the active nature walk will show greater reductions than those in the regular nature walk.
