Summary

This study aims to evaluate the acceptability, safety, and preliminary efficacy of a smartphone-delivered intervention called Therapeutic Evaluative Conditioning for Suicide (TEC-S) in reducing suicidal thoughts and behaviors (STB) among adults with recent and frequent suicide ideation.

Detailed description

The present study is a one-arm open trial designed to evaluate the safety, acceptability, and preliminary efficacy of Therapeutic Evaluative Conditioning for Suicide (TEC-S), a smartphone-delivered intervention aimed at reducing suicidal thoughts and behaviors (STB). Participants in this study will be 20 adult participants (ages 18+) who report recent and frequent STB, residing within the greater-Boston, MA area. Participants will receive 3x/daily EMA and optional access to active TEC-S. Evaluative conditioning uses classical conditioning to alter attitudes. The aim of TEC-S is to alter attitudes toward suicide and, in turn, reduce STB. EMAs will monitor STB, safety, and acceptability, and efficacy. Weekly behavioral and self-report assays will assess hypothesized treatment mechanisms. The study's aim is to evaluate the safety, acceptability, and preliminary efficacy of Therapeutic Evaluative Conditioning for Suicide (TEC-S).
