New tool aims to stop depression before it starts
NCT ID NCT06619366
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study tests whether a coach-guided, personalized risk communication tool can help prevent major depression in adults at high risk. Researchers will recruit 1,000 participants across Canada and randomly assign them to receive either the coach-guided tool or standard depression risk information. The goal is to see if the tool motivates people to use self-help strategies and seek help, ultimately reducing the number of new depression cases over 12 months.
