The study goal is to determine the feasbility and interest of monitoring mental health and non mental health related simptoms in Outpatients in order to prevent suicide.

Taking into account the strengths and pitfalls of existing suicide risk assessment methods, we have designed a system capable to combine EMA and continuous monitoring of patients using the smartphone's and/or wearable's sensors and data entry in order to monitor and predict suicide risk. For example, both poor sleep quality and disturbed appetite are clinical markers of depression, with a bidirectional relationship. Their changes could precede the increase of suicidal behavior as sleep and appetite are both influenced by mood state and regulated by the serotonergic system. Our hypothesis is that tracking mental health simptoms regularly through self-report could serve as a consistent and non-biased shortcut to assess mood state, its biological underpinnings and could potentially predict suicidal behavior.

To be eligible for the study, patients must be 18 years or older, attend an outpatient clinic or emergency departments of participating clinical services and owning an android or IOS smartphone

After agreeing to participate, clinician will collect the non-opposition for each patient. Patient with a current suicidal behavior disorder (according to DSM-5), i.e. having attempted suicide in the current year, will be test the application.
