Understanding the Associations Between Romantic Relationship Conflict, Psychophysiological Responding and Alcohol Misuse Among Emerging Adults

New York University160 enrolled

Overview

Emerging Adults (EA) engage in heavy episodic drinking (HED) at a greater quantity and frequency than any other time in their lives, which may lead to significant short- and long-term consequences. Although much is known about the influence of peers in EA alcohol use, there is a dearth of research examining the ways in which romantic partners influence EA drinking behaviors. The proposed study bridges a crucial gap in the existing literature by examining behavioral and physiological risk and resilience factors in the acute link between EA relationship conflict and alcohol consumption. EA couples will engage in two conflict resolution tasks interspersed with two puzzle tasks and two alcohol administration procedures. Because high frequency heart rate variability (HF-HRV) is associated with alcohol use and emotion regulation during stressful experiences, HF-HRV and other physiological data will be collected throughout the laboratory procedures.

Inclusion Criteria: 1. Age 21-29 years old 2. Must be in a committed romantic relationship of at least 3 months duration 3. Must report at least 2 HED episodes in the past 30 days (5 or more drinks within 2 hours for males, 4 or more drinks within 2 hours for females) 4. Must self-report that they have - on at least three occasions during the past year - consumed a quantity of alcohol that is equal to or greater than the standard dose administered for their weight in the laboratory Exclusion Criteria: 1.

Secondary Outcomes

High frequency heart rate variability (HF-HRV)

High frequency heart rate variability (HF-HRV) is a neurally-derived measure of parasympathetic activity that may partially explain the association between stressful relationship conflict and alcohol misuse. HF-HRV is a measure of the variability in interbeat intervals, or the time in between beats of the heart.

Time frame: ~3 hours
