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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
coach-guided personalized depression risk communication tool
What this could lead to
If successful, this could provide a new, cost-effective tool to prevent major depression in high-risk adults before it starts.
What could go wrong
This is an early-stage behavioral trial with no drug; results depend on participant motivation and may not generalize beyond the study population.
