Summary

This study looked at how often to check in with people after they leave a psychiatric hospital to help lower their suicide risk. About 500 patients in Shenzhen, China, received brief contact interventions (like texts or calls) at different frequencies over a year. The goal was to find the best schedule for these check-ins and see if they help reduce suicidal thoughts.
