Just-In-Time Intervention to Reduce Alcohol-Facilitated Intimate Partner Violence Perpetration

Study Overview
=================
Brief Summary
-----------------
Acute alcohol intoxication is a robust predictor of intimate partner violence (IPV) perpetration for young adult men and women; therefore, interventions delivered proximally to drinking episodes - a period of high risk - are needed to reduce alcohol-facilitated IPV. This project seeks to improve public health by delivering a just-in-time text messaging intervention proximally to drinking episodes and evaluating the impact of the intervention on alcohol-facilitated IPV in a sample of at-risk young adult men and women. Additionally, through an innovative design this project is poised to answer these important questions: whether receiving a message, when, for whom, what type, and under what conditions this just-in-time messaging intervention leads to reductions in alcohol use and IPV perpetration.
