Screening student drinking behaviors: examining AUDIT criterion validity using CIDI-based alcohol use disorder as the 'gold standard'.

Introduction: High levels of alcohol consumption among college students have been observed across countries. Heavy drinking episodes are particularly prevalent in this population, making early identification of potentially harmful drinking critical from a public health perspective. Short screening instruments such as the Alcohol Use Disorders Identification Test (AUDIT) are serviceable in this regard. However, there is a need for studies investigating the criterion validity of AUDIT in the student population. The aim was to examine the criterion validity of the full AUDIT and AUDIT-C (the first three items directly gauging consumption patterns) in a sample of college and university students using 12-month prevalence of alcohol use disorder derived from an electronic, self-administered version of the World Health Organization (WHO) Composite International Diagnostic Interview, fifth version (CIDI 5.0), which serves as the 'gold standard'. Methods: The study population of the current study is derived from the SHoT study (Students' Health and Wellbeing Study), which is a large national survey of students enrolled in higher education in Norway. In a follow-up study of mental disorders among participants of the SHoT2022 study, students were invited to complete a self-administered electronic version of the CIDI. A random sample of 4,642 participants in the nested CIDI-sample was asked to fill out a set of screening instruments, including AUDIT, before starting CIDI. Based on Youden Index maximization, we estimated the sex-specific optimal cut-offs for AUDIT and AUDIT-C in relation to alcohol use disorder, as determined by CIDI. Results: For the full AUDIT, the optimal cut-offs were 9 for males and 10 for females. The corresponding cut-offs for AUDIT-C were 6 for males and 5 for females. The same optimal cut-offs for both the full AUDIT and AUDIT-C were replicated in bootstrapped analyses with 1,000 runs. Conclusion: The full AUDIT demonstrated acceptable criterion validity with a balance between sensitivity and specificity. However, for AUDIT-C, caution should be exercised when interpreting screening results among college and university students. In conclusion, the full AUDIT is a reliable screening instrument for college and university students, while further modification may be needed for AUDIT-C in this setting.

Childhood trauma and alcohol misuse in college students: The moderating role of minimization.

BACKGROUND: History of childhood trauma as a risk factor for alcohol misuse in early adulthood is very well documented. Given the associations between childhood trauma and alcohol misuse, more work is needed to understand the factors that influence this relationship. OBJECTIVE: The purpose of this study was to examine the relationship between childhood trauma, minimization of such events and alcohol misuse in a French college student sample. PARTICIPANTS AND SETTING: A convenience sampling method was used to recruit students from several colleges located in Western France. The data set included 1180 records with complete responses. METHODS: This study employed a cross-sectional online survey. Data collection instruments included the Childhood Trauma Questionnaire Short-Form (CTQ-SF) and the Alcohol Use Disorders Identification Test (AUDIT). RESULTS: The strength of the association between CTQ score and AUDIT total score was increased by minimization score (ß = 0.122, p = .07). This result suggests that under-reporting childhood trauma experiences tends to increase the impact of such events on alcohol misuse. CONCLUSION: These findings suggest that a tendency to minimize threatening childhood events may specifically be related to increased risk of greater alcohol misuse among college students. Therefore, it may be important for clinician to assess minimization of early events in students with a history of childhood trauma.

Do hypothetical evaluations of alcohol related consequences change over time? Examining the influence of past and ongoing consequences.

OBJECTIVE: Despite experiencing alcohol-related consequences, college students continue to drink at high rates. Hypothetical evaluations of alcohol-related consequences (i.e., evaluations of where potential/hypothetical consequences lie on a spectrum from extremely positive to extremely negative) may contribute to the maintenance of drinking patterns among students. The purpose of the present study was to describe hypothetical evaluations in a sample of students mandated to an alcohol intervention, examine changes over time, and investigate the influence of both baseline and time-varying experienced consequences. METHOD: This study was a secondary data analysis from a longitudinal randomized controlled trial. Participants were 474 mandated students (Mage = 18.65; 55.5 % male, 77.6 % White). Students completed an initial baseline assessment of demographics, alcohol use, consequences, and hypothetical evaluations, and 3-month and 9-month follow-up assessments that included hypothetical evaluations and experienced consequences. RESULTS: Hierarchical linear modeling (HLM) analyses revealed significant change in hypothetical evaluations over time such that they became less negative. A piecewise model demonstrated that this change happened between baseline and 3-month, with no additional change between 3-month and 9-month. The experience of consequences at baseline did not significantly moderate changes in either time interval. Time-varying consequences also had no significant effect on same-timepoint hypothetical evaluations. CONCLUSIONS: This study is the first to examine changes in hypothetical evaluations over time among mandated college students. Counter to expectations, hypothetical evaluations became less negative at 3-month follow-up. Though preliminary, findings add to the understanding of hypothetical evaluations of alcohol-related consequences.

A confirmatory factor analysis of a revised motives for playing drinking games (MPDG-33) scale among university students in the United States.

AIM: Participating in a drinking game (DG) is common practice among university students and can increase students' risk for heavy drinking. Given the theoretical link between motivations to drink and alcohol use, careful consideration should be given to students' motivations to play DGs. In this study, we examined the factor structure, internal consistency, and concurrent validity of a revised version of the motives for playing drinking games (MPDG) scale, the MPDG-33. METHODS: University students (n = 3345, Mage = 19.77 years, SDage = 1.53; 68.8% = women; 59.6% = White) from 12 U.S. universities completed a confidential online self-report survey that included the MPDG-33 and questions regarding their frequency of DG participation and typical drink consumption while playing DGs. RESULTS: Confirmatory factor analysis indicated the 7-factor model fit the data adequately, and all items had statistically significant factor loadings on their predicted factor. All subscales had adequate to excellent internal consistency and were positively correlated with the frequency of DG participation and the typical number of drinks consumed while playing DGs (though the correlations were small). CONCLUSION: Findings suggest that the MPDG-33 can be reliably used in research and clinical settings to assess U.S. university students' motives for playing DGs.

Establishing Motivational Profiles to Drink among College Students: Converging Patterns Using Multiple Theories of Alcohol use.

Objective: While college student drinking has been studied utilizing many different theories and approaches, it is unclear how these theories may overlap in their explanation of problematic drinking. Rather than relying on one theory, examining overlap between multiple theories of alcohol use may lead to a better understanding of the motivational process underlying drinking behavior. The current study proposes that the Ambivalence Model of Craving, Behavioral Economics, and Alcohol Outcome Expectancy Theory account for the same underlying anticipatory process and sought to demonstrate this by establishing motivational profiles utilizing constructs within each theory. Methods: A total of 318 college student drinkers completed a series of surveys assessing their drinking behavior and the measures pertaining to each theory (i.e., Approach and Avoidance of Alcohol Questionnaire, Alcohol Purchase Task, Alcohol Expectancy Questionnaire). A latent profile analysis was used to establish profiles of motivational tendencies. Results: Results from the latent profile analysis indicated four profiles emerged, three of which were consistent with our hypotheses: approach, avoidance, and indifferent. The fourth motivational profile appeared to represent drinkers with an emerging approach tendency but relatively newer to drinking. The lack of ambivalent profile suggests that avoidant tendencies may develop later in response to an accumulation of experience with drinking. Lastly, these profiles demonstrated expected relationships with drinking behavior. Conclusion: This study is unique in its attempt to highlight similarities between theories. Results provide a useful integration of theories to allow for a more generalized understanding of motivational tendencies that develop in response to drinking experiences.

Safer Bars: A cluster-randomized effectiveness evaluation of alcohol-related sexual violence prevention through bar staff bystander training.

BACKGROUND: Sexual assault is consistently associated with social contexts that support high levels of alcohol consumption such as alcohol-serving establishments (i.e., bars). The significant rates of alcohol-involved sexual assault among college students demonstrate the critical need for evidence-based efforts to reduce alcohol-involved sexual assault in this population. Although bystander approaches have demonstrated some promise for reducing alcohol-involved sexual assault, to date no published studies have examined the effectiveness of implementing bystander prevention approaches with bar staff. Given the robust evidence indicating that bars serve as hot spots for sexual aggression, interventions that improve bar staff's ability to identify and intervene in sexually aggressive situations may offer a useful approach for reducing rates of alcohol-involved sexual assault. METHODS: The Safer Bars study utilizes a cluster-randomized trial design that randomizes participants at the bar level into intervention and waitlist control arms. The sample includes bars (Nbars = 56) within a three-mile proximity to the three major public Arizona universities, with an average of 10 staff members per bar (Nstaff = 564). Assessments of individual-level and bar-level outcomes occur at baseline, training completion, and 3-months post-training, with an additional individual-level assessment at 6 months. Community-level effects are assessed using GIS data regarding police dispatches. CONCLUSION: Safer Bars represents a novel, theory-driven approach to promote effective bystander behavior among bar staff working in close proximity to university campuses to reduce rates of alcohol-involved sexual assault.

Individual Differences in Substance Use Motives, Trauma, and Stress Among College-Based Polysubstance Users.

Background: Co-use of alcohol and other drugs within a certain time frame (i.e., polysubstance use) has become increasingly prevalent, particularly among college-aged individuals, but understanding motives for co-use remains limited. Polysubstance use has been associated with a higher likelihood of negative health consequences as compared to single substance use. Objectives: The current study examined associations between motivations for using alcohol, tobacco, and cannabis among college students who use multiple substances versus students using only one substance or no substances. Additionally, we examined the effect of trauma and daily stress on polysubstance use in self-report data from individuals (N=134) participating in the MAPme Study. Results: First, the observed prevalence of polysubstance use was greater than expected by chance, with most individuals co-using alcohol and cannabis. "Alcohol and Other Drug Users" were more frequently motivated to drink for social (ß=0.27, CI=[0.07, 0.44]), enhancement (ß=0.26, CI=[0.01, 0.42]) and coping (ß=0.21, CI=[0.06, 0.47]) reasons compared to individuals who consumed alcohol alone. Conclusions: Individual differences in motivations for use were partly explained by frequency of alcohol use and alcohol problem severity, but not by history of trauma or stress. Finally, while patterns of correlations among motivations for use across substances suggested a general tendency to be motivated to use substances for similar reasons, this was not supported by confirmatory factor models. Overall, shared motives may inform potential behavioral patterns for co-use of substances during college and might advise future treatment efforts.

Emerging adults tend to use multiple substances, particularly alcohol and cannabisCorrelation patterns suggest shared motives within rather than across substancesAlcohol problem severity and alcohol frequency predict motives for use.

Examining the Factor Structure and Correlates of Motives to Drink Before Attending a Virtual Social Event During COVID-19 Among University Students.

Background: Many university students pregame or drink before a social event. Pregaming carries some risk due to its link to heavy drinking. During the COVID-19 pandemic, there was limited access to many drinking venues (e.g., bars/clubs). Moreover, universities shifted to a virtual format and imposed restrictions on in-person gatherings resulting in the reliance on virtual platforms for class instruction, meetings, and social events. The pandemic facilitated changes in students' drinking behaviors, stress levels, and how they maintained social contact with others. Thus, it is conceivable that during an academic pandemic year, students may have engaged in the act of drinking before attending a virtual social event. Objectives: In the present study, we examined the factor structures/item loadings of the Pregaming Motives Measure-Virtual (PGMM-V) among students (N = 283; Mage = 21.38; women = 69.3%; White = 45.4%, Hispanic = 40.8%) from seven universities who completed an online questionnaire (Spring/Summer-2021). Items from the original Pregaming Motives Measure (Bachrach et al., 2012) were modified to reflect motives to drink before attending a virtual social event. Results: We found evidence for a 2-factor structure model of the PGMM-V which includes social/enhancement and social ease/stress. Bivariate correlations indicated that social/enhancement and social ease/stress were (a) positively associated with frequency of drinking and alcohol consumption prior to attending virtual social events, and (b) general drinking motives (social/enhancement/coping) that align with these motives. Conclusions: The PGMM-V is a promising instrument that could be used in future research designed to understand students' pregaming behaviors for virtual social events as the use of such platforms are increasingly relied upon for social engagement.

Sleep, Alcohol and Cannabis Use in College Students With and Without Attention-Deficit/Hyperactivity Disorder.

Background: Relations among attention-deficit/hyperactivity disorder (ADHD), sleep, and substance-related negative consequences are largely unknown. In this cross-sectional study, we examined associations among ADHD diagnosis, sleep, and alcohol-related consequences. We also evaluated the independent and interactive effects of sleep and ADHD on alcohol-related negative consequences, above and beyond levels of alcohol use. Methods: College students who drink alcohol with (n = 51) and without (n = 50) ADHD completed an assessment that included a diagnostic interview assessing ADHD, and questionnaire measures of sleep quality, substance use, and associated consequences. Analyses utilized a series of hierarchical linear regression models and explored these aims for cannabis use in a subset of participants (n = 52 participants that used cannabis). Results: College students who drink alcohol with ADHD reported significantly worse sleep quality and more alcohol-related consequences, relative to those without ADHD. When ADHD and sleep quality were included in the model, ADHD-but not sleep quality-was independently associated with alcohol consequences, but not cannabis consequences. There were no moderating effects of ADHD on the associations between sleep and substance-related consequences. Conclusions: Students who drank alcohol with ADHD may be particularly vulnerable to experiencing poor sleep and consequences from their substance use, compared to their heavy drinking peers without ADHD. Future, larger scale studies should consider longitudinal effects as well as underlying mechanisms of risk.

Looking out for You and Me: College students' Strategies for Preventing Sexual Assault in Drinking Contexts.

Background: Sexual assault and heavy alcohol use are prevalent and interrelated public health concerns on university campuses. Surprisingly, however, few alcohol harm reduction interventions address this intersection to help students reduce both personal and community risks for sexual assault in college drinking contexts. Objectives: In the current study, students (ages 18-24) shared strategies they use to protect themselves and others from sexual assault in college drinking contexts, as well as challenges to implementing these strategies. A series of six focus groups were conducted across two universities in the U.S. (N = 35). Participants responded to open-ended questions focused on drinking and sexual assault (e.g., What are some of the things students might do to avoid or address situations where they feel pressured of coerced to hook up or have sex when they do not want to?). Results: Thematic analyses demonstrated students' awareness of protective behavioral and bystander intervention strategies that could help reduce vulnerability to experience sexual assault for themselves or others in drinking contexts. Perceived barriers to using bystander intervention strategies included student's own and friends' heavy drinking (decreased inhibitions, loss of autonomy), ambiguity in deciphering risk (lack of familiarity, minimization, diffusion of responsibility), and gender (gender norms, power imbalances). Conclusions: This study informs the development of interventions that help students identify strategies and overcome barriers to reduce risks for sexual assault in college drinking contexts.

How Do Gain-Loss Frames and Cultural Arguments Persuade? Designing Effective Messages to Weaken College Students' Binge-Drinking Intentions.

To design effective health messages, this study investigates the effects of gain-loss framing and relevant moderating effects in the context of college students' alcohol use. Specifically, based on an online experiment, we tested the moderation effects of message-sidedness and binge-drinking behaviors using a mediation model in which the association between gain-loss framing and behavioral intentions is mediated by attitudes toward binge-drinking. Four hundred thirty-four Korean college students participated in this study. Hayes' PROCESS Macro for SPSS was employed for the analysis. The results show that loss-framing significantly increased participants' unfavorable attitudes toward binge-drinking in the one-sided message condition. Moreover, attitudes toward binge-drinking were more significantly associated with behavioral intentions to binge-drink among heavy drinkers than among non-heavy drinkers. Our findings suggest important theoretical and practical implications for the development of message-framing strategies in health campaigns designed to prevent college students' binge-drinking in collectivistic societies where the cultural meaning of drinking extends beyond the individual realm to the larger social context.

Parental Alcohol Communication and Student Drinking: Examining Potential Differences between Underage and Legal Drinking Age Students.

BACKGROUND: We explored associations between parental alcohol communication (PCA) and student drinking behavior and protective behavioral strategies (PBS) use. METHODS: College students in the United States, who had talked about alcohol with parents, (N = 251) completed an anonymous online survey in Fall 2021. Participants reported frequency of discussing 14 alcohol-related topics with parents, past 30-day drinking behaviors, and PBS use. RESULTS: We identified two forms of PCA: general alcohol information and alcohol risk information, with alcohol risk information being more common than general alcohol information. PCA was not significantly associated with drinking behavior but was associated with two types of PBS. Specifically, general alcohol information was associated with greater use of serious harm reduction and stopping or limiting drinking strategies. Additionally, legal drinking age status moderated the associations between both forms of PCA and the use of stopping or limiting drinking strategies. In general, underage students stopping or limiting drinking strategies benefited from general alcohol information but not alcohol risk information. Legal drinking age students stopping or limiting drinking strategies benefited from alcohol risk information. CONCLUSIONS: Among these students, PCA appears to have a greater impact on PBS use rather than drinking behavior. This may reflect a shift in students' beliefs about parental authority over alcohol and parents' acceptance of alcohol use by their children.

Likelihood of Young Adult Engagement in Protective Behavioral Strategies for Alcohol Use across Drinking Contexts: Implications for Adaptive Interventions.

OBJECTIVE: This study examined how young adults' likelihood to engage in protective behavioral strategies (PBS) to reduce alcohol harms varies across physical and social contexts for drinking. METHOD: We conducted an online survey with 514 heavy drinking young adults (Mage = 22.4 years, 52% women, 30% Hispanic/Latin(x), 40% non-White). Participants were asked to rate their likelihood to engage in 26 PBS generally, and specifically in six physical contexts (e.g., bar/club), and six social contexts (e.g., in a large group). We conducted regression analyses to examine the overall effect of context on the likelihood to engage in each PBS and post-hoc Tukey tests to assess pairwise comparisons of the differences in likelihood to engage in each PBS across response options for physical and social context. Analyses were conducted using the full sample, and for men and women separately. RESULTS: There were significant differences in six strategies across physical contexts; likelihood to engage in PBS varied across public and private spaces for different strategies. We also found significant differences in five strategies across social contexts; participants were more likely to engage in PBS among larger numbers of people and those who are intoxicated. There were numerous differences in pairwise comparisons of PBS engagement across physical and social contexts for women, while men demonstrated only two differences in PBS across physical context. CONCLUSIONS: Results suggest that alcohol interventions for young adults that include PBS should consider tailoring strategies to the individual and the specific context of the drinking event.

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 and non-SGM college students and (2) explore how SGM status was associated with pregaming behaviors and if SGM status moderated the association between motives and pregaming behaviors. Methods: The sample consisted of 485 college student drinkers in the US, with 19% (n = 93) identifying as SGM. All participants completed measures of past 30-day pregaming frequency and quantity (yielding a total pregaming drinks outcome) and drinking consequences experienced on pregaming days. Results: SGM participants consumed significantly fewer pregaming drinks than non-SGM participants, but did not significantly differ on alcohol-related consequences or drinking motives. The pregaming motive of intimate pursuit moderated the association between SGM status and total pregaming drinks, such that non-SGM participants with high intimate pursuit motives drank the heaviest. Conclusions: Our findings suggest that SGM students consume significantly fewer pregaming drinks than their non-SGM counterparts. However, they may be at a similar risk of experiencing pregaming consequences as non-SGM students. SGM students were less susceptible to the effect of intimate pursuit motives on pregaming drink consumption. This study offers support for past research regarding the effects of certain pregaming motives on pregaming drink consumption and consequences.

The Moderating Role of Stress Mindset on the Relationship between Drinking to Cope and Alcohol Consumption among Undergraduate College Student Drinkers.

OBJECTIVE: Previous research suggests drinking alcohol to cope with negative affect, including stress, is a risk for increased alcohol consumption and alcohol-related problems. Stress mindset, the individually held belief that stress can lead to either enhancing or debilitating outcomes, has yet to be studied within the context of alcohol use. Studying stress mindset among college students as it relates to alcohol consumption may provide important insight into heavy alcohol use in this population. METHOD: A sample of 320 undergraduates (Mage = 19.06 (SD = 0.06); 63.44% female; 65.49% White) who endorsed past-year alcohol use completed self-report measures of drinking motives, stress mindset, alcohol consumption, and alcohol-related consequences. Zero-inflated negative binomial regressions were utilized to examine the moderating effect of stress mindset on the relationship between drinking to cope and alcohol consumption. RESULTS: Stress mindset significantly moderated the relationship between drinking to cope and alcohol consumption (IRR = 0.98, se = 0.01, p < 0.05, CI = 0.96, 1.00), such that the relationship was stronger among those with a debilitating stress mindset compared to those with an enhancing stress mindset. Stress mindset did not significantly moderate the relationship between drinking to cope and alcohol-related consequences. CONCLUSIONS: Individuals with high drinking to cope scores and who hold a debilitating stress mindset may be at a particular vulnerability for heavy alcohol consumption. The present study furthers our understanding of predictors of alcohol use in a college sample and suggests the importance of future research focused on stress mindset among college student drinkers.

Comparing Drinking Game Motives, Behaviors, and Consequences Among Varsity Athletes, Recreational Athletes, and Non-Student-Athletes: A Multisite University Study.

OBJECTIVE: Among college students, student-athletes are at increased risk for heavy alcohol consumption, participation in risky drinking practices (e.g., playing drinking games [DG]), and adverse alcohol-related consequences relative to non-student-athletes. Within the student-athlete population, level of sports participation (e.g., recreational or varsity sports) can affect alcohol use behaviors and consequences, but our understanding of the extent to which level of sports participation influences engagement in DG is limited. Thus, in the present study, we examined differences in frequency of participation in DG, typical drink consumption while playing DG, negative DG consequences, and motives for playing DG among varsity, recreational, and non-student-athletes. METHOD: College students (n = 7,901 across 12 U.S. colleges/universities) completed questionnaires on alcohol use attitudes, behaviors, and consequences. RESULTS: Student-athletes (recreational or varsity sports) were more likely to have participated in DG within the past month than non-student-athletes. Among students who reported past-month DG play, recreational athletes played more often and endorsed more enhancement/thrills motives for playing DG than non-student-athletes, and student-athletes (recreational or varsity) endorsed higher levels of competition motives for playing DG than non-student-athletes. CONCLUSIONS: These findings shed light on some risky drinking patterns and motives of recreational athletes who are often overlooked and under-resourced in health research and clinical practice. Recreational and varsity student-athletes could benefit from alcohol screening and prevention efforts, which can include provision of competitive and alcohol-free social activities and promotion of alcohol protective behavioral strategies to help reduce recreational athletes' risk for harm while playing DG.

College Students' Day-to-Day Maladaptive Drinking Responses to Stress Severity and Stressor-Related Guilt and Anger.

BACKGROUND: Stress is a common part of college students' daily lives that may influence their physical activity (PA) and alcohol use. Understanding features of daily stress processes that predict health behaviors could help identify targets for just-in-time interventions. PURPOSE: This study used intensive longitudinal data to examine whether prior day stress processes predict current day PA or alcohol use. METHODS: Participants (N=58, Mage=20.5, 59% women, 70% White) were 18-to-25-year-old students who engaged in binge drinking at least twice monthly and used cannabis or tobacco in the past year. They wore activity (activPAL4) and alcohol (Secure Continuous Remote Alcohol Monitor) monitors for 11 days to assess daily PA (e.g., step counts) and alcohol use (e.g., drinking day), and completed daily surveys about yesterday's stress, including number of stressors (i.e., frequency), stressor intensity (i.e., severity), and frequency of affective states (e.g., guilt). Multilevel models examined prior day stress predicting current day PA or alcohol use. RESULTS: Participants had higher odds of current day drinking (odds ratio=1.21) and greater area under the curve (B=0.08) when they experienced greater than usual stress severity the prior day. Participants had higher current day peak transdermal alcohol concentration (B=0.12) and area under the curve (B=0.11) when they more frequently experienced guilt due to stressors the prior day. CONCLUSIONS: College students' unhealthy response of increasing alcohol use due to stress could adversely impact health outcomes. There is a critical need for interventions addressing students' ability to effectively manage and respond to the stress-inducing, daily demands of student life.

College students experience stress regularly, which may influence their physical activity (PA) and drinking behaviors. Understanding how daily stress predicts health behaviors could be useful for stress-reduction interventions. This study examined whether prior day stress predicted current day PA or alcohol use. Participants (N = 58) were 18- to 25-year-old college students who binge drank at least twice per month and used cannabis or tobacco in the past year. They wore PA and alcohol sensors for 11 days to assess daily PA and alcohol use, and completed daily surveys about yesterday's stress, including the number of stressors experienced (i.e., frequency), stressor intensity (i.e., severity), and mood responses related to stress (anger, anxiety, guilt, sadness). Participants were 21% more likely to drink and drank at higher intensity when they experienced greater than usual stress severity the prior day. Participants had higher current day alcohol use intensity when they more frequently experienced guilt due to stressors the prior day. College students' unhealthy response of increasing alcohol use due to stress could negatively impact short- and long-term health outcomes. There is a critical need for interventions addressing students' ability to effectively manage and respond to the stress-inducing, daily demands of student life.

Following social media influencers who share alcohol-related content is associated with college drinking.

INTRODUCTION: Frequent exposure to peer-shared alcohol-related content (ARC) on social media is associated with greater alcohol consumption and related consequences among undergraduates. Social media influencers also share ARC; yet, the effect of exposure to influencer-shared ARC on alcohol outcomes has not been examined. The current study examined whether following influencers who share ARC and the frequency of sharing were associated with alcohol outcomes, and associations between influencer type (e.g., actors) and alcohol outcomes. METHODS: Undergraduates (N = 528) from two universities in the United States completed an online survey assessing demographics, social media use, alcohol use and related consequences. They listed up to five influencers they followed and viewed the most content from. A series of linear regression models were conducted. RESULTS: Having a larger proportion of influencers sharing ARC was associated with greater quantity, frequency and peak drinks, but not consequences. Frequency of influencers sharing ARC was associated with greater quantity and peak drinks, but not frequency or consequences. Findings remained significant, even after controlling for peer ARC. Actor ARC, everyday person ARC and 'other' type influencer ARC were associated with several alcohol outcomes. DISCUSSION AND CONCLUSIONS: This study added to the literature by examining how following influencers who share ARC, and sharing frequency, were associated with drinking outcomes over and above exposure to peer ARC. It also examined whether ARC content from specific types of influencers was associated with alcohol outcomes. Findings highlight that the source of ARC is relevant when studying the effects of ARC exposure on college drinking.

A Dual-Process Decision-Making Model Examining the Longitudinal Associations Between Alcohol-Induced Blackouts and Alcohol Use Disorder Risk Among College Student Drinkers.

OBJECTIVE: The purpose of this study was to use a dual-process decision-making model to examine the longitudinal associations between alcohol-induced blackouts (blackouts) and alcohol use disorder (AUD) risk symptoms among college student drinkers. METHOD: Undergraduate drinkers (N = 2,024; 56% female; 87% White; 5% Hispanic) at a large northeastern university completed online surveys each semester during their first (Time [T] 1, T2), second (T3, T4), third (T5, T6), and fourth (T7, T8) years of college (87% retention across the study). Path analyses were examined testing the longitudinal associations between T1 willingness to experience a blackout, T1 intentions to avoid a blackout, T2-T8 drinking, T2-T8 blackouts, and T8 AUD risk symptoms. Hypotheses 1 and 2 tested the associations between T1 willingness, T1 intentions, T2-T8 drinking, and T2-T8 blackouts. Hypothesis 3 tested the associations between T2-T8 drinking, T2-T8 blackouts, and T8 AUD risk symptoms. RESULTS: Students experienced an average of 8 (SD = 8) blackouts during college. Approximately 1,514 (88.8%) participants reported experiencing 1 of 8 AUD risk symptoms. T1 willingness was positively associated with T2-T8 blackouts. T2-T8 drinking and T2-T8 blackouts were positively associated with T8 AUD risk symptoms. T1 willingness significantly indirectly affected T8 AUD risk symptoms through its association with T2-T8 blackouts. CONCLUSIONS: Results estimated that, on average, college student drinkers experienced eight blackouts across 4 years of college, and 88% of participants reported experiencing at least one symptom of AUD in the last semester of college. Willingness to experience a blackout influenced students' AUD risk symptoms through the number of blackouts they experienced throughout college.

Examining Alcohol-Related Blackouts and Drinking Motives Over Time Among College Women.

OBJECTIVE: Excessive alcohol consumption and its consequences among college women continues despite prevention efforts. One common consequence, alcohol-related blackouts (ARBs), are periods of alcohol-activated anterograde amnesia. The purpose of the current project is to extend the ARB and drinking motive literature by examining their relationship over time. METHOD: A sample of 424 women (88.9% White) completed online surveys assessing their ARBs and drinking motives weekly for 10 weeks. A series of hierarchical generalized linear models were estimated to examine the between-person and within-person effects of each drinking motive on repeated measures of experiencing a blackout across the time points. RESULTS: Women who report higher levels of drinking motives compared with others were more likely to report having blackout experiences. College women who reported higher levels of conformity motives did not have increased odds of experiencing a blackout. In weeks when they reported elevated levels of drinking motives, they were also more likely to experience an ARB. CONCLUSIONS: In general, college women who reported higher levels of social, coping, or enhancement motives experienced more blackouts than students who reported lower levels of these motives. Women who were underage were more likely to experience a blackout compared with women who were 21 or older. In a given week, 52.6% to 70.7% of the students consumed alcohol, and among women who drank in a given week, the prevalence of blackouts ranged from 8.5% to 14.6%. The results suggest that changes in motivational levels might provide a possible intervention point for ARBs risk.
