About this trial
This project will examine changes in depression and anxiety following a 10-week intervention promoting nature-based physical activity in mental health settings. We will recruit ten licensed therapists whose caseload includes adults with depression and anxiety. Following a training by our team, each participating therapist will recruit six clients, who will be randomly assigned to the intervention or control condition. Clients in the intervention condition will engage in walk-and-talk therapy outdoors during weekly sessions and discuss strategies for being active outdoors on their own. We will assess changes in depression, anxiety, and nature-based physical activity in both groups.
