Alcohol and "Heat of the Moment" Sexual Decision Making

HIV transmission remains a significant public health concern, especially among men who have sex with men (MSM). Condomless anal intercourse (CAI) continues to be the major route of transmission for MSM. Thus, to reduce the incidence of HIV, it is critical to identify how contextual risk factors influence CAI and develop behavioral strategies that modify risk factors directly or reduce their influence on behavior. This study will examine the mechanisms through which one of the central contextual risk factors, heavy drinking, influences sexual decision processes in the natural environment and test the benefit of a brief intervention designed to reduce sexual risk behavior among those who engage in heavy drinking.

Inclusion Criteria:Participants must be at least 18 years of age, cisgender man who has had condomless anal intercourse with another man in the past 3 months, engage in heavy drinking (assessed by either by weekly NIAAA guidelines [> 14 for men], and/or a heavy drinking episode in the past month [> 4 drinks on an occasion]), have a smartphone.Exclusion Criteria:Individuals who have HIV-infection, currently using PrEP or are in an exclusive monogamous sexual relationship are excluded. Individuals with history of bipolar disorder, schizophrenia, other psychotic disorder, or current suicidal intent will also be excluded. Current treatment for alcohol use disorder or substance use disorder. Those who are unable to provide one or more individuals who will likely know where they are at follow up will be excluded.
