About this trial
This project extends the investigators' previous research regarding the intersecting risks of alcohol, sexual risk behavior (SRB), and sexual aggression (SA) in male drinkers who have sex with women by examining the mediating and moderating roles of both intrapersonal and interpersonal emotional factors. While independent streams of research consistently document alcohol's role in SRB and SA, the investigators' work has demonstrated that these behaviors are related, and that alcohol exacerbates their likelihood both independently and synergistically. The researchers' investigations focus on a particular type of SRB: men's resistance to condom use with female partners who want to have protected sex. Condom use resistance (CUR) is common and normative among young male drinkers, with up to 80% of men reporting engaging in CUR. Of particular concern, research demonstrates that up to 42% of men report using coercive CUR tactics such as emotional manipulation, deception, condom sabotage, and force to obtain unprotected sex. Investigators will evaluate hypotheses that distal and proximal emotional and alcohol factors influence in-the-moment SRB/CUR intentions as well as daily alcohol use and SRB/CUR. The investigators will also examine whether the relationships among assessed variables are similar across experimental and naturalistic settings. That is, investigate the extent to which men's responses in the lab parallel their real-world drinking and SRB/CUR behaviors, particularly regarding self and partner emotions, empathy, and interpersonal stress.

Treatments tested in this trial
Alcoholic Beverage
BehavioralParticipants will consume an alcoholic beverage (vodka mixed with fruit juice) that is the equivalent of 3-4 standard alcoholic drinks based on their body weight.
Non-alcoholic Beverage
BehavioralParticipants will consume a nonalcoholic beverage (fruit juice) that is the isovolemic equivalent of 3-4 standard alcoholic drinks based on their body weight.
Partner Negative Mood Manipulation
BehavioralParticipants will engage in a laboratory task and will then report their own and their partner's emotions following the task.
Partner Positive Mood Manipulation
BehavioralParticipants will engage in a laboratory task and will then report their own and their partner's emotions following the task.
Treatment groups
Trial outcomes
Primary outcomes
Mean score of sexual risk intentions
Self-reported ratings of unprotected sex likelihood in a hypothetical scenario Scale range: 1 (not at all likely) to 7 (very likely). A higher value is a worse outcome. This is one total scale (no subscales). Items are averaged to compute a mean score.
Secondary outcomes
Sexual risk behavior
Number of unprotected sexual intercourse events
