What this trial studies

This study evaluates the relationship between sleep quality, appetite changes, and social exclusion with suicidal ideation and behavior using ecological momentary assessment (EMA) via smartphone applications. A total of 1044 participants who have recently attempted suicide will be monitored over six months using two smartphone apps—one for explicit data collection and another for implicit data collection through mobile sensors. The study aims to identify real-time predictors of suicidal risk and develop personalized algorithms to assess this risk based on behavioral markers. An auxiliary study will also involve 300 patients using actimeters to gather additional data.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have consulted for a suicidal crisis within the last week and own a smartphone.

Not a fit: Patients with severe mental health conditions such as schizophrenia or those under guardianship may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved real-time monitoring and prevention strategies for individuals at risk of suicide.

How similar studies have performed: Other studies using ecological momentary assessment have shown promise in identifying risk factors for suicidal behavior, suggesting this approach could be effective.
