Wearable Technology and Alcohol-Facilitated Intimate Partner Violence

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.

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.

Eligibility Criteria:
Inclusion Criteria:

1. Any gender identity; any race or ethnicity; any sexual orientation; aged 21-70 years.
2. Married, cohabiting, or in a committed relationship for ≥ 6 months.
3. English fluency and cognitive functioning sufficient to provide informed consent and participate accurately (score ≥ 26 on the Mini-Mental Status Exam \[MMSE\]).
4. At least one partner within each dyad must meet DSM-V diagnostic criteria for current AUD (assessed by the QuickSCID) and consume ≥ 2 hazardous drinking episodes (i.e., 4 or more drinks for women, 5 or more for men in ≤ 2 hours) per month in the past three months.
5. At least one partner within each dyad must endorse ≥1 instance of IPV with their current partner in the past 6 months (assessed by the Revised Conflict Tactics Scale \[CTS-2\]).
6. Maintenance of psychotropic medications on a stable dose for at least 4 weeks before study initiation.

Exclusion Criteria:

1. Meeting DSM-5 criteria for a history of or current psychotic or bipolar disorders.
2. Meeting DSM-5 diagnostic criteria for moderate or severe drug use disorder (e.g., cannabis). Concurrent mild drug use disorders are acceptable due to the marked co-occurrence in AUD populations.
3. Alcohol withdrawal as indicated by CIWA-Ar scores \>8.
4. Current suicidal or homicidal ideation and intent.
5. Serious cardiovascular health conditions (e.g., pacemaker, cardiac arrhythmia, hypertension) because the safety of HRV-B has not yet been established in these populations.
6. Treatment on medications such as lithium, methadone, alpha or beta blockers or cholinergic/ anticholinergic medications likely to confound normative cardiovascular responding.
7. Current neurologic conditions or history of traumatic brain injury.
8. Severe and unilateral IPV in the past 6 months.
9. Current pregnancy.
