Summary
This study tested whether promoting a free web and mobile tool called StopBlues could reduce suicides and suicide attempts in the general population. Over 100,000 adults in 42 French communities took part, with some communities actively promoting the tool and others not. The goal was to see if easy access to mental health resources and support could make a real difference at a population level.
