Background: Suicide is a major public health issue that represents a leading cause of years of life lost and entails substantial costs for health and welfare systems. Prevention of suicide among high-risk individuals remains an unmet clinical need. Smartphone-based Ecological Momentary Assessment (EMA) consists of asking daily questions to patients, thus capturing their real-time thoughts and behaviors. A subtype of EMA, passive EMA, monitors people’s behavior with smartphones’s sensors. Both EMAs can define the digital phenotype of suicidal patients. Ecological Momentary Intervention (EMI) incorporates a therapeutic element, representing one step further

Objectives: Our study aimed to assess the effectiveness of a combination of EMA and EMI to decrease suicide re-attempts in at-risk adult patients at seven hospitals in four sites of Spain (Cataluña, Andalucía, Asturias, and Madrid), representing a joint catchment area of 2,5 million people (5% of Spanish population).
