SmartCriseS - Smartphone Survey of Suicidal Risk

Sleep and appetite disorders as well as social exclusion, have been linked to the emergence of suicidal ideation (SI) and suicide attempts.This study aims to evaluate the relationship between those factors and suicidal ideation and behaviour. To assess those factors an ecological momentary assessment (EMA) desing will be used. EMA will be carried out using 2 applications integrated into the smartphone of participants (Android or iOS), one to make an explicit data collection with questions and another one for the implicit collection of data from mobile sensors. 1044 suicide attempters will be included in three sites and followed for 6 months. Participants will be evaluated at inclusion and at the end of follow-up. The hypothesis is that sleep, appetite and social exclusion factors collected with the smartphone application will be linked to the intensity of death wish, suicidal ideations and suicidal attempts. An auxiliary study will also be led with 300 patients carrying an actimeter for the 30 first days after inclusion. This will help collecting more accurate data on various sleep parameters.
