Attempted Suicide Short Intervention Program: a Randomized Controlled Trial

University of Zurich100 enrolled

Overview

"Attempted Suicide Short Intervention Program" (ASSIP) is a brief psychotherapy intervention after suicide attempts in psychiatric patients. The study aims to analyse the efficacy in a controlled trial by comparing number of patients with suicide attempts in a control group with treatment as usual and an intervention group with treatment as usual and ASSIP intervention. Further, the study aims at indentifying electrophysiological, sociodempgraphical or smartphone-derived parameters for prediction of further suicide attempts.

Suicide is the second leading cause of death among the 14-40 years old in Switzerland. Every year around 800'000 people all over the world die due to suicide (WHO, 2017). Preceding suicide attempts and self-harming behaviour have been found to be the main risk factor for completed suicide. The "Attempted Suicide Short Intervention Program" (ASSIP) has been designed to reduce further suicide attempts and suicide in patients after a suicide attempt. This study aims to replicate the findings of another study (Gysin-Maillart, Schwab, Soravia, Megert, \& Michel, 2016) that show the efficacy of ASSIP. Further, it is intended to identify predictors for positive treatment outcome, i.e. a reduction of further suicide attempts in patients that had already committed a suicide attempt. Main objective: Assessment of efficacy of ASSIP by comparison of the number of patients that committed suicide attempts in the intervention (ASSIP) and the control group. Secondary objectives: • Identification of sociodemographic, clinical, electrophysiological and smartphone-based marker predicting the treatment outcome, rehospitalization rates and treatment costs Identification of predictors of treatment efficacy of ASSIP (by means of electroencephalogram parameters, electrocardiogram parameters, sensing app parameters, sociodemographic parameters and voice/video material parameters. Identification of electrophysiological representations of suicidality (patient group, control group, healthy controls).
