Brief Summary

The proposed study uses an experimental design to establish causal support for the role of internalized stress, pertaining to uncertainty with regard to one's sexual orientation, in contributing to heavy drinking behavior. Following exposure to internalized sexual stigma, physiological and psychological stress responses are expected to increase alcohol consumption in adults who are uncertain about their sexual orientation, especially among females, and following consumption, the physiological effects of ethanol and beliefs about the effects of alcohol are expected to alter relations between exposure to sexual stigma and the alleviation of psychological distress. Showing that physiological stress responses, whether driven by the pharmacological effects of ethanol or expectancies regarding its effects, can account for known alcohol-use disparities, particularly in bisexual/bi+ communities, would contribute a great deal to knowledge on the biology of addiction and inform subsequent interventions that seek to regulate stress reactivity.

Inclusion Criteria
  • Cisgender
  • Age 21-29

  • Scores on the Alcohol Use Disorders Identification Test (AUDIT) that indicate mild or moderate risk for potential alcohol use disorder
Exclusion Criteria

  • Female persons who are currently pregnant (established with urine pregnancy test) or actively trying to get pregnant (self-report in the screening survey).
  • Persons who are currently in treatment or who have ever been in treatment for a substance use disorder.
  • Persons who have essential medications that disallow the consumption of alcohol.

GroupInterventionDescription
Relevant Stressor Condition with No EthanolRelevant Trier Social Stressor Test (TSST)Participants complete the Relevant Trier Social Stress Test (TSST), which asks participants to prepare a 5-minute speech on how their sexuality has developed over time. Participants are then assigned to receive a placebo priming beverage (with no ethanol) to consume over 10 minutes. Participants will consume the initial placebo drink, which is intended as a priming cue. Next, participants will be given a free period of an additional 20 minutes in which participants can consume up to three additional placebo cocktails, which do not contain ethanol.
Irrelevant Stressor Condition with No EthanolIrrelevant Trier Social Stressor Test (TSST)Participants complete the Irrelevant Trier Social Stress Test (TSST), which asks participants to prepare a 5-minute speech on how their gender identity has developed over time. Participants are then assigned to receive a placebo priming beverage (with no ethanol) to consume over 10 minutes. Participants will consume the initial placebo drink, which is intended as a priming cue. Next, participants will be given a free period of an additional 20 minutes in which participants can consume up to three additional placebo cocktails, which do not contain ethanol.
Control Stressor Condition with No EthanolPlacebo Trier Social Stressor Test (TSST)Participants complete the Control Trier Social Stress Test (TSST), which asks participants to prepare a 5-minute speech on a recent book participants read, or a recent movie participants saw. Participants are then assigned to receive a placebo priming beverage (with no ethanol) to consume over 10 minutes. Participants will consume the initial placebo drink, which is intended as a priming cue. Next, participants will be given a free period of an additional 20 minutes in which participants can consume up to three additional placebo cocktails, which do not contain ethanol.

Participants are then assigned to receive a priming beverage containing ethanol to consume over 10 minutes. Participants will consume the initial drink containing ethanol, which is intended as a priming dose. Next, participants will be given a free period of an additional 20 minutes in which participants can consume up to three additional cocktails, which contain ethanol. The initial drink in the alcohol condition will contain 0.3 g/kg (males) or 0.2 g/kg (females) of 80-proof ethanol, adjusted for body weight, and subsequent drinks will contain 0.1 g/kg of ethanol.
