Can a mindset therapy boost exercise in people with low mood?
NCT ID NCT05407935
First seen Sep 03, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This trial tests whether a program called ACTivity, which uses acceptance and commitment therapy to encourage physical activity, can help low-active adults with depressive symptoms become more active. Participants are randomly assigned to either ACTivity or a relaxation-based comparison program, both including goal-setting and self-monitoring. They attend weekly virtual sessions for 8 weeks and are followed for 6 months, with a YMCA membership provided to both groups. The study measures physical activity levels and depressive symptoms to see if the approach is feasible and promising.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Acceptance and commitment therapy (ACT) combined with standard physical activity promotion strategies, compared to relaxation training with the same strategies
- What this could lead to
- If it works, this could point toward a practical, group-based program that helps people with depressive symptoms become more physically active, potentially easing their mood.
- What could go wrong
- This is an early feasibility trial with a small number of participants, so it may not show clear benefits. The program requires weekly virtual sessions, and results may not apply to everyone with depressive symptoms.
