The Effects of Alcohol Intoxication on Sexual Risk Behavior in Men Who Have Sex with Men
Experimental research has shown consistent evidence for a causal effect of alcohol on sexual risk behavior relevant to HIV. However, event-level research has produced mixed results. Limited research has assessed alcohol and sexual risk in the context of pre-exposure prophylaxis (PrEP) and treatment as prevention (TasP; i.e., maintaining an undetectable HIV viral load). The present study explores the event-level relationship between alcohol use an…
Recent alcohol use and binge drinking behaviors among sexual minority undergraduate women and sorority members
Purpose Sorority members and sexual minority (SM) women engage in high rates of alcohol consumption and risky drinking in the college environment. Little is known of the alcohol use behaviors of SM sorority members, who may be especially at-risk. This paper aims to not only further investigate SM undergraduate women’s alcohol use broadly but also to understand how sorority affiliation may potentially impact their use patterns. Design/methodology/…
For Whom Does Chemsex Increase Sexual Risk? Considering Pre-Exposure Prophylaxis (PrEP), Antiretroviral Therapy (ART), and the Dual Control Model
Background: Chemsex, or the use of specific substances (e.g., methamphetamines, GHB/GBL) to enhance sexual experiences, is a well-documented risk factor for sexual risk behavior and subsequent HIV transmission among men who have sex with men (MSM). However, it is unclear why chemsex contributes to sexual risk and how HIV prevention measures, such as pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART), impact this relationship. The pr…
Prevalence and Correlates of Condom Use Resistance Among Men Who Have Sex with Men Reporting Recent Heavy Alcohol Use and Condomless Sex
Condom use resistance (CUR) involves use of coercive and non-coercive tactics to persuade a sexual partner who wants to use a condom to forgo use. Given that limited research has explored use of CUR tactics among men who have sex with men (MSM), the present study sought to estimate the prevalence and correlates of CUR among MSM. Participants (N = 261 MSM reporting recent heavy alcohol use and condomless anal sex) completed measures assessing CUR …
Associations Between Food Restriction, Alcohol and Marijuana Use and Co-Use, and Consequences Among College Students
BACKGROUND: Simultaneous alcohol and marijuana use (SAM) and food restriction on days students intend to drink are associated with an increased risk of substance use-related consequences. However, these negative outcomes have been studied mostly in alcohol-only use contexts. Little is known about the combination of alcohol, marijuana, SAM, and food restriction. Therefore, the current cross-sectional study investigated whether alcohol, marijuana, …

An Examination of Pregaming Behavior and Motives among Sexual and Gender Minority College Students
Introduction: Pregaming is a popular but high-risk drinking behavior common among college students. Although sexual and gender minority (SGM) college students are a vulnerable population with regards to hazardous alcohol use and alcohol consequences, there is currently limited research investigating the pregaming behavior of this group. The present study aimed to (1) examine mean level differences in pregaming behaviors and motives between SGM an…
Using Latent Profile Analysis to Examine Cannabis Use Contexts
Objective College students represent a large portion of the population, and report high rates of cannabis use and related negative outcomes, including interpersonal problems, risky behaviors, or physical dependency. The contexts in which students use cannabis (e.g., at a party, when feeling down or depressed, after a fight with a loved one) likely affect their risk of experiencing consequences. We aimed to discern profiles of cannabis use context…
Sexual Violence Victimization and Pregaming Protective Behavioral Strategies Among College Students
BACKGROUND: Sexual violence is a major public health concern that has a detrimental impact on mental health, physical health, and academic performance. College students represent a population that is at an increased risk of experiencing sexual violence. Alcohol use, and more specifically, heavy drinking during pregaming events, is associated with increased risk of sexual violence. Studies have demonstrated that protective behavioral strategies ha…
A Deeper Dive into Young Adults’ Experiences with E-Cigarettes, E-Cigarette Cessation, and Transitioning to Cigarette Smoking
Introduction: E-cigarette use among young adults is prevalent, with some voicing their desire to quit using e-cigarettes but needing support to do so. Young adults who use e-cigarettes are at risk for progressing to smoking combustible cigarettes, placing them at risk for severe health consequences. Limited research exists describing young adults’ lived experiences with using e-cigarettes, e-cigarette cessation, and progression to combustible cig…
Bidirectional Associations Between Pain and Perceived Stress Among Veterans
OBJECTIVE: Military veterans who were injured in combat very often report pain along with co-occurring perceived stress and preexisting depressive disorder. The systems model of pain is a theoretical model suggesting that pain and perceived stress are bidirectionally associated at the within-person level, and associations are heightened among those with depressive disorder. However, the systems model of pain has not been adequately tested. Testin…
Military sexual trauma, childhood trauma, and combat trauma
Social support significantly predicted posttraumatic growth, with varying impacts across trauma classes. Interventions could be vital for survivors of MST, childhood trauma, or compounded traumas to enhance posttraumatic growth among military veterans.

Web-based personalized normative feedback to decrease stigma and increase intentions to seek help
Use of cannabis to manage symptoms of mental and physical health conditions during pregnancy
There is need for reduced stigma and open communication between pregnant persons who use cannabis and their providers in discussing how to manage their mental and physical health symptoms. Understanding the various symptoms for which individuals use cannabis during pregnancy to self-treat can inform these conversations and the expansion of harm reduction strategies
Associations between service use and behavioral health trajectories among young adults experiencing homelessness
Secondary Outcomes of a Brief Group Alcohol and Risky Sex Intervention for Emerging Adults Experiencing Homelessness
AWARE is a four-session group-based motivational enhancement intervention designed to reduce substance use and sexual risk behavior among emerging adults experiencing homelessness. Expanding on promising intervention effects on substance use and risky sex outcomes, this study explored intervention effects on changes in secondary outcomes from baseline to 12-month post-intervention: depression, physical health (general health ratings, physical sym…
Sociodemographic and Behavioral Risk Correlates of PrEP Interest and Use Among Young Adults Experiencing Homelessness in Los Angeles
Young adults experiencing homelessness (YAEH) are at elevated risk for HIV compared to their stably housed peers. Preexposure prophylaxis (PrEP) is highly effective at preventing HIV infection, yet YAEH have been largely overlooked in PrEP efforts to date despite YAEH reporting high overall interest in PrEP. We assessed individual, social, and structural variables associated with PrEP interest and use among a sample of 195 YAEH (ages 18-25) recru…
How Do College Students Use Their Free Time? A Latent Profile Analysis of Leisure Activities and Substance Use
College is a critical period of transition to independence and the substantial amount of time that students have to participate in leisure activities may be conducive to substance use. However, little is known about the associations between leisure activities and substance use over time, or whether these associations differ by residential status (i.e., living with parents vs. on their own). Using latent profile analysis, this study found six dist…

Self in the Service
PURPOSE: Drinking is common among young adult veterans. Previous research has established that veterans' drinking is more strongly associated with veteran versus civilian drinking norms. The present research extends these findings by examining the influence of self-identification both with other veterans and with civilians as moderators of the association between perceived norms and drinking. METHODS: = 3.44) were recruited via Facebook to partic…
Effects of alcohol, expectancies, and partner type on condom use in college males
Sexually active heterosexual college males (N = 93) provided data on over 1,500 sexual encounters. Alcohol consumption, expectancies about alcohol's impact on condom use, and partner type each contributed to use of a condom. Partner type covaried with alcohol consumption and condom use. The men consumed significantly more alcohol with new partners, followed by casual partners, and then by regular partners. In contrast, they were more likely to us…
