Phone calls that save lives: study tests social bond theory against suicide
NCT ID NCT05227183
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how a telephone support program called VigilanS helps prevent suicide in people who have previously attempted it. Researchers think the program works by restoring social bonds, especially in those who feel isolated. 120 adults aged 18 to 55 who are already part of VigilanS will take part in a social stress test to measure stress hormones and heart rate. The goal is to understand why the program is effective, not to test a new treatment.
