Objective: Hookup behaviors (HUBs; i.e., sexual activity outside an exclusive relationship with no mutual expectation of romantic commitment) are prevalent on college campuses and are linked with alcohol use and sexual assault. There is limited understanding of risk factors for consensual and coercive HUBs. We examined the proximal associations between alcohol use and consensual and coercive HUBs and the moderating influence of positive urgency and alcohol-related sexual affect and drive expectancies among college men.

Method: Ninety-nine college men completed a baseline assessment and 60 consecutive daily surveys assessing their alcohol use and HUBs.

Results: An alcohol use day increased the odds of a consensual and coercive HUB, compared to no HUB. An alcohol use day decreased the odds of a consensual HUB, versus a coercive HUB, in the models that included alcohol-related sexual affect and drive expectancies. Only alcohol-related sexual affect expectancies was a significant moderator. An alcohol use day significantly associated with a consensual HUB, compared to no HUB, among college men at low, B = .93, p = .009, OR = 2.53 (95% CI: 1.27, 5.06), and high, B = 1.93, p < .001, OR = 6.87 (95% CI: 4.32, 10.92), levels of alcohol-related sexual affect expectancies.

Conclusions: Results suggest that greater alcohol-related sexual affect expectancies may increase the odds of an alcohol-facilitated consensual HUB among college men. An alcohol use day increases the odds of engaging in a HUB and increases the odds of a coercive HUB, compared to a consensual HUB. Additional research is needed to identify risk factors for coercive HUBs.

Objective: The primary aim of this study was to assess and adjust for measurement non-equivalence (bias) by sex, race/ethnicity, and co-occurring social identities (sex x race/ethnicity) for the Marijuana Effect Expectancies Questionnaire-Brief (MEEQ-B) among Black, Latinx, and Non-Latinx white youth. The second aim was to determine how group comparisons change after accounting for possible measurement bias.

Method: Black, Latinx, and Non-Latinx white youth from the Adolescent Brain and Cognitive Development Study Follow-up 3 (n=8,982; mean age=12.91; SD=0.65; 47.28% female; 15.03% Black, 22.93% Latinx, 62.04% Non-Latinx white) completed the MEEQ-B. Moderated nonlinear factor analysis (MNLFA) generated positive and negative expectancies factor scores accounting for non-equivalence. Analyses contrasted group differences by sex, race/ethnicity, and these co-occurring social identities using original (unadjusted) versus MNLFA-generated scores adjusted for measurement non-equivalence.

Results: Measurement non-equivalence was observed for positive and negative expectancies across sex, race/ ethnicity and their co-occurring social identities. MNLFA revealed between-group differences at the factor and item level. Further, comparisons of original (unadjusted) and MNLFA-generated adjusted scores revealed that unadjusted scores underestimated or did not detect some group differences in positive expectancies identified using adjusted scores, and unadjusted scores underestimated how much lower negative expectancies were in Black and Latinx relative to non-Latinx white youth.

Conclusions: Results highlight the need for caution when interpreting scores of a measure like the MEEQ-B that has not undergone measurement equivalence testing and demonstrate how failing to adjust for non-equivalence can result in biased estimates of positive and negative expectancies, particularly when used with diverse populations.

Objective: An inability to correctly perceive chemosensory stimuli can lead to a poor quality of life. Such defects can be concomitant with excess alcohol consumption, but a large-scale cohort study linking these effects is lacking. This study aimed to investigate the impact of chronic alcohol consumption on chemosensory function by analyzing data from the NHANES 2013-2014, involving 395 participants categorized by alcohol intake behavior: 219 no-intake, 136 light-intake, and 40 risky-intake groups.

Methods: Chemosensory function was assessed using a self-reported Chemosensory Questionnaire along with objective tests for taste (quinine solution) and smell (appetitive and hazardous odors). Adjusted regression analyses were conducted, controlling for age, gender, smoking status, and multiple pairwise comparisons. Weighted regression analyses were also performed.

Results: Risky drinkers had significantly lower odds of identifying quinine (bitter taste) compared to light drinkers (OR = 0.37, p-adjusted = 0.04). Risky drinkers also had higher odds of identifying appetitive odors like strawberry (OR = 5.44, p-adjusted = 0.03) but lower odds for detecting hazardous odors like natural gas (OR = 0.11, p-adjusted = 0.001) compared to light drinkers. Additionally, light drinkers identified the leather scent more effectively than no drinkers (OR = 2.54, p = 0.02).

Conclusions: Chronic alcohol consumption, particularly at risky levels, is associated with altered chemosensory function. These findings emphasize the importance of assessing chemosensory symptoms in individuals with alcohol-related behaviors.

Objective: Personalized normative feedback interventions show efficacy in reducing health risk behaviors (e.g., alcohol use, sexual aggression). However, complex personalized normative feedback interventions may require manual methods of inputting participant data into graphics, which introduces error, and automated approaches require substantial technical costs and funding and may limit the types of feedback that can be provided.

Method: To make personalized normative feedback more accessible, we outline a method of using easily accessible software programs including IBM Statistical Package for the Social Sciences (SPSS), Microsoft Excel, and Microsoft PowerPoint, to create and display complex personalized normative feedback graphics. We also describe methods through which personalized normative feedback graphics can be created within a larger preventive intervention for alcohol and sexual assault in college men.

Results: We first provide step-by-step instructions for collecting data and then creating semi-automated syntax files within SPSS and Excel to merge participant data into complex personalized normative feedback graphics in Excel. To do so, we append annotated syntax in text and in supplemental material. Next, we outline the process of creating risk feedback graphics, whereby individual items or exact wording of items are displayed back to the participant. Finally, we provide guidance regarding the process of translating graphics from Excel for viewing via PowerPoint without having to manually update PowerPoint slides for each presentation.

Conclusions: Via the described syntax and graphic generation, researchers are then able to create semi-automated personalized normative feedback and risk feedback graphics. This tutorial may help in increasing the dissemination of complex personalized normative feedback interventions.

Objective: As the legalization of adult-use cannabis has expanded to include almost half of the states in the U.S., substance use-related enforcement responsibilities for state and local law enforcement agencies may have changed. We assessed the use of cannabis and alcohol enforcement strategies at local and state levels, and in legal and non-legal cannabis states.

Method: We conducted surveys of 1,024 local law enforcement agencies, 53 state alcohol beverage control agencies and 48 state patrol agencies. We calculated the prevalence of cannabis enforcement strategies and their analogous alcohol strategies and analyzed differences across legal and non-legal cannabis states. We assessed associations between cannabis enforcement strategies, cannabis legalization status, and agency and jurisdiction characteristics.

Results: Cannabis enforcement strategies were less common than their analogous alcohol strategies. The percentage of agencies conducting enforcement of cannabis-impaired driving and of public use of cannabis did not differ significantly across agencies in legal and non-legal states. Agencies in cannabis legal states (compared to non-legal states) were more likely to train officers in identifying cannabis impairment among drivers (RR=1.23, 95% CI=1.08-1.42). Several local agency and jurisdiction characteristics were associated with a higher likelihood of conducting cannabis enforcement but results were inconsistent across strategies.

Conclusions: Our study shows that cannabis enforcement strategies were used less than analogous alcohol strategies in legal and non-legal jurisdictions, suggesting that increased cannabis enforcement could lead to reductions in public health harms. This study provides a foundation for much needed research on cannabis and alcohol enforcement during a changing cannabis legalization landscape.

Existing tools for making workplace and roadside determinations of marijuana-based impairment are inadequate. They either merely imitate tools used to identify alcohol- based impairment without taking into account important differences between these molecules, or they are pseudoscientific "police science." Legalization of marijuana use must be accompanied by urgent efforts and dedicated funding for the development and implementation of practical, accurate, and objective methods for on-the-spot determination of whether a person is dangerously impaired by marijuana.

Objective: For thousands of years, people have used alcohol to reduce their sensitivity to physical and emotional pain. Previous research has shown that alcohol increases pain threshold. Previous research has also shown that pain threshold is positively associated with aggression. This research tests the novel hypothesis that the relationship between alcohol and aggression is mediated by increased pain threshold.

Method: To replicate findings, two independent laboratory experiments were conducted (Experiment 1: N=543; Experiment 2: N=327). In both experiments, male and female heavy social drinkers were randomly assigned to consume either an alcohol or a placebo beverage. Next, they reported their pain level to electric shocks that increased in a stepwise manner until the level was described as "painful," which was defined as the pain threshold level. Finally, they delivered painful electric shocks to an ostensible opponent each time they won a competitive reaction time task. Participants won half of the 34 trials (randomly determined). Shock intensity and duration levels were standardized and summed across the 34 trials to create a more comprehensive measure of aggression.

Results: Participants who consumed an alcoholic beverage had a higher pain threshold level than did those who consumed a placebo beverage. The less pain participants felt themselves, the more pain they inflicted on their ostensible partner via electric shock. Results were nearly identical across both experiments.

Conclusions: These findings provide novel evidence regarding one possible reason why intoxicated people behave more aggressively than sober people do. Alcohol intoxication increases aggression partially through its effect on increasing pain threshold.

Objective: Despite adverse health consequences associated with early substance use initiation, less is known about the influence of genetic risk on initiation and environmental characteristics that may moderate these associations, particularly among African Americans. We examined whether genetic risk for alcohol and cannabis use disorder, and nicotine dependence, is associated with age of initiation of these substances, and whether community disadvantage and parental monitoring moderate these associations in a sample of African American youth.

Method: Participants (n=1,017; 56% female) were initially recruited for an elementary school-based universal prevention intervention trial. At age ~20, participants reported on age of initiation of alcohol, tobacco, and cannabis use and provided a saliva or blood sample. At age ~12, caregiver reports on parental monitoring were obtained, along with census-tract data to measure community disadvantage. Hypotheses were tested using Cox Proportional Hazard Models.

Results: Higher alcohol use disorder PRS was associated with later alcohol initiation (HR=0.78, 95% CI =0.65-0.94). Cannabis use disorder and nicotine dependence PRSs were not associated with initiation of these substances. We observed an interaction between the cannabis use disorder PRS and parental monitoring; among individuals with high cannabis use disorder PRS, high monitoring was associated with earlier cannabis initiation, whereas among individuals with low PRS, low monitoring was associated with earlier initiation.

Conclusions: Findings largely indicate that PRS for substance use disorders are not associated with age of initiation among African American youth. Parental monitoring may influence the association between cannabis use disorder PRS and age of cannabis initiation, but replication of our findings is warranted.

Objective: This paper explores methodological opportunities, challenges, and potential solutions for alcohol administration research that uses a virtual reality (VR) analogue for sexual aggression.

Method: We briefly review relevant sexual aggression, alcohol administration, and VR literatures. The strengths and limitations of different types of analogues are described.

Results: Most existing sexual aggression analogues use sexual assault scenarios which end the same way for all participants, who are then asked how they would respond in that situation. Studies using these analogues have produced valuable findings regarding alcohol's role in sexual aggression; however, one important limitation is that participants can distance themselves from the situation before responding. VR provides highly immersive behavioral analogues that require participants to make quick decisions; thus they are less likely to be impacted by social desirability. In VR, participants make multiple decisions based on the feedback they receive from their virtual dating partner and the ending depends on the choices they make. For example, VR analogues can allow participants to select dates who are intoxicated or to encourage their virtual dating partner to drink alcohol. Thus, researchers can model different patterns of responses and strategies used to attempt to obtain sex, which can then be used to develop interventions targeted for individuals with different types of risk profiles.

Conclusions: There are strengths and limitations associated with all experimental proxies. The field would benefit from greater discussion of the essential elements of sexual aggression and if these vary for different types of perpetrators and situations that involve alcohol.
