BRITE 2.0: A Just-in-time Adaptive Intervention for Suicide Safety Planning in Adolescents

The goal of the MRT is to optimize the ViraBrite intervention by randomly assigning participants to various combination of notification timing (e.g., morning, midday, evening). Participants will download the ViraBrite suicide safety planning app that integrates automated algorithms (i.e., just in time adaptive intervention features) to facilitate increased engagement with coping skills and pushes safety planning materials to users at periods of high risk (i.e., increases in emotional distress). The MRT will last for 4 weeks for each participant. Each day, participants will receive prompts ("nudges") according to a micro-randomized pattern that encourage them to access the ViraBrite app and utilize suicide safety planning skills. One decision point will occur per day. At each decision point, participants will have a seventy-five percent chance of receiving a nudge. Given that they are randomized to receive a nudge, participants have a 33.3% chance of receiving a notification at one of three time points: morning, midday or evening. The MRT will also investigate the impact of estimated emotional distress as a moderator of responding to the nudge. Specifically, measures of distress including 1. Self-report of daily mood, 2. Linguistic markers of distress (i.e., first person pronoun use) and 3. Geolocation will be explored as moderators of engagement with nudges.
