Summary

This project seeks to develop interactive treatment options to successfully reduce AUD and IPV concurrently. The purpose of the study is to examine the usability, feasibility, and acceptability of wearable activity trackers (like a smart watch) and use of a cell phone application (app) among couples. The investigators are also testing the use of this device and app will affect alcohol use and couple conflict. This study involves a screening phase and a 28 observation period where participants are asked to wear a smart watch, complete assessments and provide feedback.

Detailed description

Alcohol use disorder (AUD) and acute alcohol intoxication are well-established precipitants of intimate partner violence (IPV). Approximately one third of U.S. adults experience IPV during their lifetimes. Recent data indicate that IPV negatively impacts AUD treatment and increases risk of relapse. Although behavioral treatments targeting AUD and IPV are effective for some women and men, efficacy is commonly limited by high dropout rates, poor working alliance, and low readiness to change. As a result, there is a critical and persistent need to develop dynamic treatment options to successfully reduce AUD and IPV concurrently. Mitigating maladaptive physiological reactivity in the form of respiratory sinus arrhythmia measure of heart rate variability (HRV) is one promising pathway to achieve this goal. HRV is an autonomic biomarker of arousal relevant to AUD pathophysiology, alcohol consumption, and treatment outcomes. HRV is also an emerging mechanism underlying alcohol-facilitated IPV. Growing evidence suggests that biofeedback interventions to modulate physiological, emotional, and behavioral stress responses are feasible, acceptable, and may reduce AUD symptoms such as craving to improve long-term AUD recovery. This data suggests that remote, self-administered biofeedback interventions hold promise as a discreet, accessible and low cost standalone or adjunct treatment option for AUD patients with high risk behaviors such as IPV. Thus, the primary objective of the proposed project is to use wearable technology to develop proof-of-concept of HRV as a biomarker of alcohol-facilitated IPV in naturalistic settings. The secondary objective is to examine the preliminary usability, feasibility, and acceptability of a remote, self-administered HRV-B intervention.

Interventions

Type	Name	Description
DEVICE	Heart Rate Variability-Biofeedback (HRV-B) via Smartwatch Device Intervention	Participants will wear activity trackers equipped with continuous ambulatory physiological monitoring and geolocation. Ecological momentary assessment (EMA; 4 times daily plus optional event-triggered reports) of alcohol use, couple conflict including IPV, and affect will be completed via smartphone application for 28 days. During days 21-28, participants will also be prompted to complete a 10 minute self-administered HRV-B session at least once daily. Subjective usability, feasibility, and acceptability of HRV-B will be assessed. HRV-B will guide participants in an evidence-based paced breathing technique (about 6 breaths per minutes) using visualization on thier mobile device of thier real-time respiratory and cardiac parameters. During days 21-28, participants will also be prompted to complete a 10 minute self-administered HRV-B session at least once daily. Subjective usability, feasibility, and acceptability of HRV-B will be assessed.
