Objective: Sexual assault perpetration is widespread among young men. According to the Confluence Model, hostile masculinity and impersonal sex are trait-level factors associated with sexual assault perpetration likelihood. Additionally, state-level factors, including alcohol intoxication, current emotions, and ability to modulate one's emotions, have been tied to sexual assault perpetration via the I3 Model. This study integrates these trait- and state-level factors into a single model to enhance its predictive power and better inform future interventions.

Method: Data were collected from 2019 to 2023. Young, single, nonproblem drinking men, who had been sexually active with a woman within the past month (N = 282; 34.8% people of color), completed background questionnaires and were randomly assigned to a positive or negative mood induction, and then to consume alcohol (target peak breath alcohol concentration = .08%) or a control beverage before projecting themselves into a hypothetical, sexual scenario. Then, men indicated their likelihood of engaging in nonconsensual sexual activity with their hypothetical partner (i.e., perpetration likelihood).

Results: A moderated-mediation structural equation model demonstrated that trait hostile masculinity and impersonal sex interacted with state alcohol intoxication and mood to predict state sexual arousal. State sexual arousal subsequently interacted with state impulsivity to predict state difficulties modulating emotions, which predicted perpetration likelihood during the hypothetical scenario.

Conclusions: Integrating trait- and state-level factors is of paramount importance to understanding sexual assault prevention. Interventions targeting emotional modulation during sexual situations may be especially useful among aroused or impulsive individuals, due to their mood, alcohol intoxication, and attitudes regarding hostile masculinity and impersonal sex.

Objective: Drinking intention is a predictor of heavy-drinking episodes and could serve as a real-time target for preventive interventions. However, the association is inconsistent and relatively weak. Considering the affective context when intentions are formed might improve results by revealing conditions in which intention-behavior links are strongest and the predictive power of intentions is greatest.

Method: We investigated the links between drinking intentions reported in the morning and same-day drinking behavior, moderated by positive and negative affect (PA, NA) in a sample of heavy-drinking young adults. Participants wore the SCRAM continuous alcohol monitor transdermal alcohol sensor anklet for 6 consecutive days in their natural environments and responded to daily ecological momentary assessments that included morning intentions to drink and PA/NA items. Drinking events and patterns were measured using morning-report counts and features from the sensor. Bayesian gamma-hurdle and Poisson multilevel models with noninformative priors tested day-level associations. We hypothesized that drinking intention-behavior associations would be strongest on days with high levels of PA, but we did not hypothesize directionality for the NA effect given the conflicting results in previous literature.

Results: Day-level drinking intention-behavior associations were stronger on days with higher versus lower PA according to sensors features. Associations were also stronger on days with lower versus higher NA.

Conclusions: The strength of intention-behavior links may partly depend on the affective contexts in which intentions are formed. Results could fine-tune intervention approaches by elucidating the affective contexts in which intentions may more clearly link to drinking behavior to reduce the intensity of an episode-better anticipating problematic drinking among young adults.

Objective: Simultaneous cannabis and alcohol use is common, but few studies have examined normative perceptions of simultaneous use. This study examined unique associations of baseline descriptive norms for simultaneous use (i.e., perceptions about others' simultaneous use) with simultaneous use behaviors assessed via daily surveys.

Method: Young adults reporting frequent simultaneous use (N = 150) completed baseline measures of descriptive norms for the frequency of simultaneous use and the amounts of cannabis and alcohol consumed during typical simultaneous use occasions. Further, participants completed measures of descriptive norms for the frequency and quantity of cannabis and alcohol use in general (not limited to simultaneous use). Norms were assessed referencing both peer and friend groups. Following this assessment, participants completed 21 daily smartphone surveys assessing cannabis and alcohol use each day. Simultaneous use was operationalized as same-day use of cannabis and alcohol.

Results: Multilevel models revealed that, controlling for descriptive norms for cannabis and alcohol use in general, perceiving more frequent simultaneous use among friends (but not peers) was significantly associated with a greater tendency to engage in simultaneous use relative to cannabis-only use across days. Further, perceiving heavier cannabis and alcohol consumption during simultaneous use occasions among friends (but not peers) was significantly associated with greater quantities of cannabis and alcohol consumed, respectively, across simultaneous use days.

Conclusions: Descriptive norms for simultaneous use contribute uniquely to simultaneous use behavior, over and above norms for cannabis use and alcohol use in general. Findings may inform norms-based interventions for young adults who engage in simultaneous use. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Previous research has found that momentary positive affect precedes alcohol use, whereas results have been more mixed for negative affect.

Method: This study replicates and builds upon this literature by using a heavy drinking sample, half lesbian, gay, bisexual, trans, queer/questioning, and other minoritized sexual and gender identities (LGBTQ+) individuals.

Results: This study found that positive affect was related to subsequent alcohol use, but the relation was weaker for LGBTQ+ individuals compared to cisgender-straight individuals. Negative affect was negatively related to alcohol use in the overall sample, but LGBTQ+ individuals reported drinking more drinks following increased negative affect, and this effect was not significant for cisgender-straight individuals. Finally, positive affect was related to subsequent cannabis use, and negative affect was negatively related to cannabis use, which did not differ based on sexual orientation and gender identity.

Conclusions: Future research should explore the impact of minority stress on the association between affect and drinking behaviors to understand the differential role of affect on LGBTQ+ individual's substance use. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: Transdermal alcohol concentration (TAC) sensors provide a multidimensional characterization of drinking events that self-reports cannot. These profiles may differ in their associated day-level alcohol-related consequences, but no research has tested this. We address this using multilevel latent profile analysis.

Method: Two hundred twenty-two young adults who regularly engage in heavy drinking (M_age = 22.3, 64% female, 79% non-Hispanic White) responded to surveys and wore TAC sensors for 6 consecutive days. We tested whether four previously identified TAC profiles: (1) high-fast (8.5% of days), (2) moderate-fast (12.8%), (3) low-slow (20.4%), and (4) little-to-no-drinking days (58.2%) differed in numbers of negative and positive consequences and in the odds that both consequence types occurred on the same day.

Results: High-fast (incident rate ratio [IRR_low-slow] = 6.18; IRR_{little-to-no-drinking} = 9.47) and moderate-fast (IRR_low-slow = 3.71; IRR_{little-to-no-drinking} = 5.68) days contained more negative consequences compared to low-slow and little-to-no-drinking days. High-fast (IRR = 2.05), moderate-fast (IRR = 1.88), and low-slow (IRR = 1.43) days contained more positive consequences than little-to-no-drinking days. The odds of having only positive consequences were highest on low-slow, χ²(3) = 9.10, p < .05, days but the odds of experiencing both consequence types increased on moderate-fast and high-fast days, χ²(3) = 39.63, p < .001.

Conclusions: Compared to little-to-no-drinking days, TAC profiles indicative of drinking (high-fast, moderate-fast, and low-slow) contained more negative and positive consequences. However, the odds of experiencing only positive consequences were highest among low-slow days and decreased on moderate-fast and high-fast days as the odds of negative consequences rose. These findings provide novel evidence reinforcing harm reduction approaches that seek to maximize positives and minimize negatives of alcohol consumption through emphasis on slow-paced, low-volume drinking.

Objective: To understand the influence of acute alcohol consumption on the recall and recognition of warning messages.

Method: Participants (n = 82) were randomly assigned to a condition where they consumed alcoholic beverages (target blood alcohol concentrations of 0.06%-0.08%) or a condition where they consumed juice. Participants in both conditions then gambled on preprogrammed slot machines in a casino-themed room with four pop-up warning messages appearing twice each. After the gambling session, participants in both conditions completed a filler task followed by free recall and recognition assessments.

Results: Most participants (81%) recalled the gist, or the general idea, of the warning messages. However, participants in the alcohol condition underestimated the total number of messages they viewed to a significantly greater extent than those in the juice condition. Participants in the alcohol condition were also significantly less accurate in recognizing messages than participants in the juice condition. Participants in the juice condition were significantly more likely to recall the self-appraisal message than participants in the alcohol condition. There were no other significant differences in the recall of specific messages between conditions.

Conclusions: Individuals who are moderately intoxicated are just as likely as nonintoxicated individuals to understand the general idea of warning messages but may have greater difficulty recalling specific details within those messages. Those who are intoxicated may have difficulties engaging in self-appraisal, indicating that messages that are focused on the financial consequences of gambling may be more impactful.

Objective: Young adults experiencing homelessness are at high risk for alcohol-related consequences, but protective behavioral strategies (PBS) have not been investigated as a harm reduction approach in this population. This study examines longitudinal associations between PBS and alcohol-related consequences following a group-based alcohol intervention.

Method: Data come from AWARE, a randomized controlled trial of a group-based motivational intervention to reduce substance use and risky sex compared to usual care. Participants include 276 young adults experiencing homelessness (M_age = 22.08, 30% female, 84% non-White) receiving drop-in center services in Los Angeles County, California. Surveys were conducted at baseline and 3-, 6-, 12-, and 24-month follow-up. Bivariate latent change score models examined cross-lagged associations between PBS and alcohol consequences for participants who drank at least once over the course of the study, controlling for demographics and intervention condition.

Results: PBS were associated with significant wave-to-wave reductions in alcohol consequences (δ range = -2.53 to -11.22), and alcohol consequences were associated with significant reductions in PBS usage between the 3- and 6-month follow-ups (δ = -0.02, p = .01) and between the 12- and 24-month follow-ups (δ = -0.08, p = .004). In addition, the AWARE intervention was associated with increased PBS usage between the 3- and 6-month follow-ups (δ = 0.30, p = .02).

Conclusions: Among young adults experiencing homelessness, greater use of PBS is associated with significant reductions in alcohol consequences over time. Furthermore, PBS may increase following a group-based motivational intervention. PBS are a promising harm reduction strategy for this population.

Objective: Alcohol use offers social benefits for young adults, but also carries risk of significant negative consequences. Better understanding of processes driving alcohol use for those who experience negative consequences can prevent these harms. These at-risk young adults likely have drinking patterns in common and patterns unique to each individual. Evidence for these processes have been limited by methods that fail to capture the complex, heterogeneous, multivariate nature of drinking. We overcome these limitations with idiographic computational models.

Method: We studied a sample of 97 young adults who regularly binge drink and experience negative drinking consequences. Participants completed daily surveys for 120 days. We estimated temporal networks of each person's drinking patterns by searching all possible dynamic relations among self-reported alcohol consumption and various cognitive, motivational, and emotional constructs. This method allowed us to identify common and uncommon drinking processes in a data-driven manner.

Results: We found clear patterns of drinking characteristic of this population (i.e., shared by 60%-100% of the sample) in which young adults drink more per occasion, when they expect positive outcomes and are motivated to get drunk and enhance social experiences, which leads to positive and negative consequences. We also identified subsets of participants with uncommon (i.e., shared by < 51% of the sample) drinking patterns.

Conclusions: Most young adults may continue to drink despite experiencing negative drinking consequences, because it also satisfies their desire for fun and social connection. Additionally, subsets of young adults have relatively uncommon drinking patterns that may reflect risk or resilience factors. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Objective: We examined whether hangover-related rumination-repeatedly dwelling on negative aspects of yesterday's drinking while hungover the following morning-predicts changes in three dimensions of heavy episodic drinking (HED) over time.

Method: N = 334 emerging adults (aged 19-29) from three Eastern Canadian universities who had recently experienced a hangover completed online self-report questionnaires at baseline (Wave 1) and 30 days later (Wave 2; 71.6% retention). HED was assessed in frequency (number of HED episodes), perceptions (how participants perceived the extent of their heavy drinking), and quantity (greatest number of alcoholic drinks consumed in a single HED episode) over the past 2 weeks.

Results: Levels of HED frequency, perceptions, and quantity declined overall from Waves 1 to 2. Exploratory factor analysis established two factors of hangover-related rumination: intrusiveness (unwanted thoughts about the previous night's drinking) and regret (desire to change future drinking behavior). Structural equation models revealed that intrusiveness at Wave 1 predicted the maintenance of higher frequency and perceptions of HED at Wave 2, even as these HED measures were generally declining; regret at Wave 1 also predicted the maintenance of HED perceptions at Wave 2. Neither Wave 1 hangover rumination factor predicted changes in HED quantity at Wave 2. Models controlled Wave 1 variables, including the relevant HED outcome, overall hangover severity, total number of hangovers, generalized anxiety symptoms, sex, age, and data collection site.

Conclusion: Hangover-related rumination factors are associated with the maintenance of higher HED frequency (intrusiveness factor) and HED perceptions (intrusiveness and regret factors), suggesting risk for problematic alcohol consumption.

Objective: Alcohol use is common in older adults and linked to poor health and aging outcomes. Studies have demonstrated genetic and environmental contributions to the quantity of alcohol consumption in mid-to-late life, but less is known about whether these influences are moderated by sociodemographic factors such as age, sex, and educational attainment. This study sought to better understand sociodemographic trends in alcohol consumption across the second half of the life course and their underlying genetic and environmental influences.

Method: Primary analyses were based on 64,140 middle-aged or older adult twins (40-102 years) from 14 studies in the Interplay of Genes and Environment Across Multiple Studies consortium. We harmonized a measure of weekly alcohol consumption (in grams of ethanol per week) across all studies.

Results: Older age was associated with lower alcohol consumption, primarily for adults over age 75, for individuals with higher education, and for males. Trends were similar across birth cohorts and after excluding current abstainers. At mean age 56, alcohol use was moderately heritable in females (.34, 95% CI [.26, .41]) and more heritable in males (.42, 95% CI [.38, .45]). Heritability was lower in older aged adults and in females with higher education.

Conclusions: This study represents the largest twin study of alcohol consumption in middle-aged and older adults. Results highlight that genetic and environmental factors influence alcohol consumption differently across age, sex, and educational attainment and that intervention efforts may need to be tailored based on individuals' backgrounds.
