Examining the relationship between social norms, alcohol-induced blackouts, and intentions to blackout among college students

Social/Party Incentives Increase the Risk of Heavier Alcohol Use in Impulsive Individuals

BACKGROUND

Impulsivity is associated with excessive drinking and negative alcohol-related consequences. However, studies have not used an in-vivo approach (i.e., daily diary) to examine how the effect of impulsivity on excessive alcohol use could be moderated by context-specific mechanisms, such as incentives.

METHOD

The study recruited a sample of young adults (n = 102, 61.8% females), who, for two weeks, responded to questions about their total number of drinks and the incentives (alcohol incentives and social/party incentives) that influenced their decisions to drink. At baseline, participants completed a questionnaire assessing trait impulsivity.

RESULTS

The findings indicated a significant main effect of social/party incentives and alcohol incentives on the total number of drinks consumed, such that individuals decided to drink more alcohol on days when they reported higher levels of either incentive dimension. The results also revealed that only social/party incentives interacted with impulsivity, such that highly impulsive individuals decided to drink more at events with more social/party incentives.

CONCLUSIONS

Findings highlight that highly impulsive individuals appear to be more responsive to social/party incentives at drinking events. Future research could benefit from continued exploration of social rewards as potential precursors to heavy drinking in highly impulsive individuals.

Associations among sexual assault history, alcohol use, blackouts, and blackout intentions among college women

Background: Links between alcohol-induced blackouts and sexual assault (SA) are understudied. We tested whether: (1) history of blackouts, past 30-day blackouts, and past 30-day blackout intentions would be higher among women with histories of SA relative to women without; (2) baseline history of blackouts, past 30-day blackouts, and blackout intentions would predict an increase in SA severity (i.e., a continuous variable that considers SA tactic type and assault frequency) at a one-year follow-up. Methods: 1721 undergraduate women completed a baseline survey and 313 completed the follow-up. Results: Women with SA history had 2.10 higher odds of history of blackouts, 1.47 higher odds of past 30-day blackout during "one" drinking episode, 1.78 higher odds of blackout during a "few" drinking episodes, 3.21 higher odds of blackout during "most/all" drinking episodes, and 1.54 higher odds of blackout intentions in the last 30-days. Longitudinally, history of blackouts and past 30-day blackouts at baseline were associated with an increase in SA severity at follow-up, when peak drinks were not controlled. Conclusion: Longitudinal findings provide some evidence that lifetime history of blackouts and past 30-day blackouts are significant predictors of an increase in SA severity at follow-up and therefore an essential target for interventions.

Opioid misuse and mental health in college student populations: A national assessment

BACKGROUND

Despite growing concern about opioid misuse and mental health of college students, little is known about this population who are at high risk of co-occurrence and unmet needs. This national study aims to estimate the prevalence of opioid misuse, examine correlates with anxiety and depression symptoms, and quantify help-seeking behaviors among U.S. college students.

METHODS

Data come from students in the Healthy Minds Study between 2017 and 2020 (n = 176,191). Validated screening tools assessed mental health symptoms (PHQ-9, GAD-7). Marginal effects of logistic regression models estimate the effect of opioid misuse on mental health symptoms, help-seeking and academic performance.

RESULTS

782 students indicated past month opioid misuse. Student opioid misuse was associated with 24.1 percentage point increase in the probability of screening positive for anxiety/depression (p < 0.001) and 3.6 percentage point increase in the probability of informal help-seeking (p = 0.017). Less than half of students with opioid misuse and a positive depression/anxiety screen received any treatment in the past year.

LIMITATIONS

Limitations to this study include: possible non-response bias, as it is unknown whether students with opioid misuse may be differentially-likely to respond to the survey; differing time frame for opioid misuse and mental health questions; and data was collected prior to the COVID-19 pandemic.

CONCLUSIONS

This large, multi-campus study underlines the need for more partnership between substance use and mental health services on campus. It also highlights that college peers could receive training in ways to best help students who misuse opioids, directing them to on- or off-campus care.

Navigating college campuses: The impact of stress on mental health and substance use in the post COVID-19 era

The college years are one of excitement and often thought of as a dream like setting of growth, creativity, and independence. This exciting time can be marred by the onset or exacerbation of mental health conditions, alcohol, and/or drug dependence. This writing looks to explore the world of college mental health and the changes the provisions of this type of care has undergone during and after the COVID-19 pandemic. We look at the staggering rates of diagnosed mental health diagnoses and mental health related symptoms that may undermine a student's ability to meet their full growth and academic potential. We look to explore different health settings where college age students are accessing care and how that care is being delivered (e.g. community vs on-campus, telehealth vs in-person). We also aim to highlight specific mental health conditions (e.g. anxiety, depression, suicidality, PTSD) and specific student stressors (e.g. participating in athletics, socioeconomic pressures) to underscore the message that the mental health of college age students is an area that needs continued study and engagement of all parties involved in student development and well-being.

Tracking Changes in the Endorsement of Injunctive Drinking Norms in Response to the COVID-19 Pandemic Using Longitudinal Alignment Analysis

The onset of the pandemic saw shifts in messaging around the acceptability of alcohol consumption at different times and contexts. A psychometric analysis of responses to injunctive norms may reveal important differences in specific aspects of norms that were influenced by the pandemic. Study 1 used alignment analysis to evaluate measurement invariance in low- and high-risk injunctive norms across samples of Midwestern college students from 2019 to 2021. Study 2 used an alignment-within-confirmatory factor analysis (CFA) approach to replicate the solution from Study 1 in an independent longitudinal sample (N = 1,148) who responded between 2019 and 2021. For Study 1, the latent mean for high-risk norms was significantly higher in 2021, and the endorsement of four specific norms also differed. In Study 2, increases in latent means for low- and high-risk norms were observed across 2020 and 2021, and differential endorsement emerged for one high-risk norm item. Examining scale-level changes in injunctive drinking norms provides insight into how college students' perceptions changed in response to the COVID-19 pandemic.

The Interaction of Cannabis Consumption with Heavy Episodic Drinking and Alcohol-induced Blackouts in Relation to Cannabis Use Consequences Among Recent Undergraduate College Cannabis Users

Introduction

Risky alcohol use patterns, characterized by heavy episodic drinking (HED) and alcohol-induced blackout, are prevalent in college students. However, it is not clear if experiencing HED and blackout among college-attending cannabis users heightens risk for adverse cannabis use consequences. The purpose of this study was to examine whether heavy episodic drinking and blackout episodes moderate the relationship between cannabis consumption and cannabis use consequences among college students.

Methods

Undergraduate college students (n = 4331) were recruited from a Midwest University in 2021. This analysis used a subset of data from past 6-month cannabis users (n= 772; 17.8% of the full sample). Among cannabis users, 64.5% identified as female and 87.8% were White with an average age of 19.99 (SD=2.88). A linear regression was conducted with two two-way interactions of cannabis consumption and HED frequency as well as cannabis consumption and alcohol-induced blackout episodes.

Results

Results showed a statistically significant positive association between cannabis consumption and cannabis use consequences (B=0.73, p<.001), adjusting for the other variables in the model. Blackout, but not HED, was a significant moderator (B=0.19, p=.003).

Discussion

The findings of this study indicate that blackout experiences amplify the relationship between cannabis use and cannabis-related consequences among college students. This underscores that blackouts not only signal a risk of problematic drinking but also exacerbate the association between cannabis use and its negative consequences.

Conclusion

Findings may inform college campus interventions targeting cannabis and alcohol concurrent-users who experience alcohol-induced blackouts to reduce their additional risk for cannabis-related consequences.

Interventions to increase naloxone access for undergraduate students: A systematic review of the literature

OBJECTIVE

To identify and describe interventions that increase access to naloxone for undergraduate students.

METHODS

A systematic review across 4 databases identified interventions that expand access to naloxone at colleges in the United States from 2015-2023. Three reviewers extracted the following data to create a narrative synthesis and summary of program elements: setting, rationale for intervention, timeline, intervention components, study size, collaboration, sustainability, outcomes and results.

RESULTS

Seven articles met inclusion criteria. Institutions' implemented naloxone interventions due to concerns for student safety and/or student overdose fatalities. Three universities collaborated with their School of Pharmacy for program design and/or dissemination, while two partnered with state-based naloxone distribution programs. Most programs combined opioid-overdose/naloxone training; four distributed naloxone kits. Three studies included pre/post-outcomes, and all reported increases in participant knowledge, attitudes, and/or ability to respond to an overdose.

CONCLUSIONS

Our results indicates an opportunity for wide-scale implementation of undergraduate naloxone programs within US colleges. However, more rigorous implementation research is needed to identify barriers and facilitators to program feasibility, acceptability, and participation.

Protective strategies and motivations to control drinking among Brazilian college students: a qualitative study

BACKGROUND

To develop prevention programs or early interventions to reduce alcohol consumption and related problems among college students, it is essential to understand their motivations for drinking and the spontaneous (effective and non-effective) strategies they employ to control, considering the social and cultural contexts influence. This study aimed to explore these factors and the student's application of selfcare in different situations and environments, as well as to identify their reasons for not drinking.

METHODS

The students were invited to participate using a snowball sampling, up to the theoretical saturation point. Qualitative individual semi-structured interviews were carried out and the interviews contents were analyzed using the NVivo software. The participants were 23 college students between 18 and 24 years old, with diverse patterns of alcohol use (low-risk to suggestive of dependence).

RESULTS

Data analysis highlighted three main themes: (a) Contexts (such as bars, "open bar" parties and others) and consumption patterns; (b) Protective Strategies (such as stop-drinking intervals, eating before or during drinking, returning home in the company of a friend); (c) Motivations to control drinking (such as sense of responsibility, bad previous experiences, family and religious issues). Protective strategies and motivation to control drinking were perceived to be less prominent in specific contexts that favor high alcohol consumption, as open bar parties.

CONCLUSIONS

Motivations and protective strategies varied according to the drinkers' profile, social situations and settings in which they consumed alcohol. The results highlight the need for preventive interventions planned for specific drinking patterns and contexts.

Daily-level associations between alcohol use cognitions and normative perceptions among adolescents: An intensive longitudinal study

BACKGROUND

Adolescence is an important developmental period in which to understand the cognitive underpinnings of risky alcohol use. Normative perceptions, such as descriptive and injunctive norms, are one of the strongest and most consistent predictors in adolescent drinking research. Thus, it is essential to examine which drinking cognitions (e.g., attitudes, prototypes, perceived vulnerability) are associated with normative drinking perceptions using repeated daily-level data among adolescents. The present study assessed associations between drinking cognitions and normative perceptions using an intensive daily longitudinal design.

METHODS

Participants were ages 15-17 years (N = 306; 61.4% female; Mage (SD) = 16.0 (0.8)) who were part of a larger ecological momentary assessment study (EMA) on drinking cognitions and alcohol use. The study design consisted of a 3-week EMA burst design (8 surveys per week, up to 2x/day) that was repeated quarterly over the 12-month study. The present analyses used the afternoon assessment for all measures.

RESULTS

Our multilevel model results demonstrated that drinking attitudes, prototypes of a typical drinker, and perceived vulnerability were positively associated with both descriptive and injunctive drinking norms between individuals and within individuals across days.

CONCLUSIONS

Current findings have important clinical implications as they demonstrated how specific drinking cognitions were associated with variability in normative perceptions at the daily level. Findings support the delivery of intervention messaging to adolescents on days when drinking attitudes, prototypes of a typical drinker, and perceived vulnerability are elevated.

The Relationship between Drunkorexia, Alcohol, and Blackouts Among College Students: An Exploratory Study

College drinkers commonly report blacking out (i.e., alcohol-induced amnesia), and those who drink with the intention to blackout are at risk for harmful consequences. Drunkorexia (i.e., restriction of calories on planned drinking days) is a high-risk behavior potentially associated with blacking out. Informed by the Theory of Planned Behavior (TPB), this study explores blackout experiences and intentions to blackout association with drunkorexia. College students (n=2335) who primarily identified as female and White participated via an online survey. Participants received a $3 coupon for completion of the study. Consistent with the literature, 40% and 60.7% participants reported experiencing blackouts and drunkorexia respectively in the last year. Informed by the TPB, a structural equation model assessed if more frequency blackout experiences (IV) related to drunkorexia behaviors (DV1) and alcohol behaviors (DV2), and if there was a significant indirect effect through blackout intention. The model fit the data well (CFI=.98, TLI=.95) and suggests that more frequent blackout experiences relate to more drunkorexia experiences (R²=.04) and higher levels of alcohol consumption (R²=.44). In addition, the relationship between blackout experiences and drunkorexia flows through intentions to blackout (i.e., a significant indirect effect). Findings are consistent with TPB, which suggests intentions predict health behavior. Future interventions should consider modifying intentions and other possible TPB constructs to minimize high risk alcohol consumption and drunkorexia behaviors.

Where, When, and How Alcohol Use Occurs During Air Force Technical Training

INTRODUCTION

Alcohol use is prevalent among military personnel, with many engaging in binge drinking behaviors. Military trainees are unique, in that they experience an enforced alcohol ban for 8 weeks while in Basic Military Training. However, they are also typically young adults, who consume alcohol at higher rates than any other age group. The current study aimed to describe alcohol consumption among trainees, determine when, where, and with whom Airmen drank for the first time during Technical Training, and if these patterns were significantly different based on descriptive norms (i.e., beliefs about how many other individuals engage in a certain behavior) related to alcohol use, given that most military members consume alcohol. Last, we aimed to determine if alcohol consumption or potential alcohol use disorders were significantly different based on descriptive norms.

MATERIALS AND METHODS

Airmen (n = 599) were recruited at Joint Base San Antonio-Fort Sam Houston during their last week of Technical Training to complete a survey. Study procedures were approved by the 59th Medical Wing Institutional Review Board. Participants were asked about their beliefs related to how many other Airmen drink alcohol (i.e., less than 50%, 50%, or greater), their own experiences with alcohol (e.g., how much they drink compared with consumption before military service, blackouts after drinking during Technical Training), and when, where, and with whom they consumed alcohol for the first time after beginning military training.

RESULTS

Over half of the Airmen reported not engaging in drinking behaviors during Technical Training. Among those who reported drinking one or more drinks during Technical Training, most reported drinking the same amount or less than they did prior to Basic Military Training. The majority of Airmen reported that they had "maybe" experienced blackouts from drinking since Technical Training. Most Airmen drank for the first time with another someone who was not an Airman, at a restaurant, home, or other place off base, and while they were on leave. Results indicated no significant differences between groups related to beliefs about how many Airmen drink during Technical Training and where, when, and with whom Airmen drank for the first time since joining the Air Force. There were also no differences in Alcohol Use Disorders Identification Test scores or drinks per week between these normative belief groups.

CONCLUSIONS

Almost half of Airmen resume drinking after alcohol restrictions are lifted during Technical Training but maintain low numbers of drinks consumed per week and low risk for alcohol use disorders, which may indicate that this is an opportune time for intervention to prevent alcohol consumption from escalating over time. Airmen reported drinking for the first time with another Airman off base during leave. Focusing on how Airmen navigate alcohol-related decision-making while their responsibilities are reduced, or how other Airmen influence their decisions to engage in risky drinking, may help prevent alcohol use rates from increasing post-enforced ban.

Gender, acculturation, and alcohol-related consequences among college students of color

OBJECTIVE

The present study examined if identification with mainstream American culture (acculturation) and heritage culture (enculturation) are differentially associated with blackouts and other drinking consequences among male and female college students of color.

PARTICIPANTS

Participants were college students (N = 150) who self-identified as a racial/ethnic minority and endorsed blackouts in the past year.

METHODS

Regression models were used to examine gender-by-acculturation/enculturation interaction effects on alcohol-induced blackout and other alcohol-related consequences.

RESULTS

While acculturation was not significantly associated with either drinking outcome, enculturation showed a significant relationship with blackout frequency. Gender moderated this relationship; greater enculturation was associated with increased blackout frequency among male but not female students.

CONCLUSIONS

The present findings suggest the importance of considering the interplay between enculturation and gender in understanding alcohol use among college students of color. Men who endorse high levels of enculturation may be at an increased risk of experiencing negative drinking-related consequences.

Examining the impact of early college experiences on the cumulative number of alcohol-related consequences

OBJECTIVE

To estimate the total number of alcohol-related consequences students experience during 4 years of college and examine early college indicators that result in higher rates of consequences.

METHOD

Undergraduate drinkers (N = 1,744; 58% female; 87% White; 5% Hispanic) at a large northeastern university completed an online survey at the end of the fall and spring semesters during their first (T1, T2), second (T3, T4), third (T5, T6), and fourth (T7, T8) years of college (87% retention across the study). First, descriptive statistics were calculated to estimate the total number of alcohol-related consequences students experienced across all 4 years of college. Second, a structural equation model was examined to identify early college indicators that influence individuals experiencing more cumulative consequences.

RESULTS

Students experienced an average of 102 (SD = 89.91) alcohol-related consequences during 4 years of college. Next, early parental approval of consequences, but not peer drinking norms, were positively associated with students' willingness to experience consequences, which in turn, were positively associated with higher alcohol consumption and greater total consequences.

CONCLUSIONS

Results estimated that, on average, students experienced 102 alcohol-related consequences across all 4 years of college. Parental approval of consequences influenced students' total consequences through their willingness to experience consequences and drinking behaviors. Findings from the current study have several important implications for interventions.

Social norms and club drug use of young adult college students during Music Week

Background: Young adult college students have high rates of substance use, theoretically related to social norms. Behavioral norms refer to the quantity of substances that students think others use, and attitudes refer to how much students or others approve of substance use. Prior research has shown a relationship between behavioral norms, student attitudes, and perceived parental attitudes and alcohol and marijuana use. However, the relationship between social norms and use of club drugs (e.g., MDMA) has not been studied.Objective: The purpose of this cross-sectional study was to expand knowledge about young adult college student social norms and club drug use.Methods: 200 young adult undergraduates (Women = 97, 49%) were recruited from a campus recreational facility on a large private Southeastern university in April 2019. Students self-reported behavioral norms, student attitudes, parental perceived attitudes, club drug use during a typical week and during music week, and substance use consequences.Results: Logistic and negative binomial regressions showed that student attitudes were significantly related to club drug use in a typical week (OR = 2.07, p = .005), during music week (OR = 2.08, p = .001), and consequences of use (RR = 1.23, p < .001), but behavioral norms and perceived parental attitudes were not.Conclusions: Findings build on social norms research with alcohol and marijuana use. Attitudes may be more important to consider than behavioral norms or perceived parental attitudes for interventions to reduce club drug use.Young adults (18-25 years old) have a high risk for substance use; both alcohol and drug use increase throughout adolescence and peak in young adulthood.^1-3 Young adults have high heavy episodic drinking (35% past month) and illicit drug use (25% past month), with greater MDMA use (10% vs 7%) and marijuana use (35% vs. 15%) than other adults.⁴ Alcohol and marijuana use has been linked to many negative consequences, such as blackouts, physical injuries, unprotected sex, and even death.^5,6 Club drug use is also linked to negative consequences, such as memory lapse, headaches, loss of energy, trouble sleeping, depression, confusion, anxiety, irritability, nausea, and changes in heart rate and blood pressure.^7,8.

Multidimensional Acculturation, Acculturative Stress and Alcohol or Drug Use of Adult Latinx Immigrants

Few studies have used a multidimensional acculturation framework, i.e., cultural practices, identity, and values, to investigate links with alcohol or drug use of Latinx immigrants to the U.S. This cross-sectional study tested links between measures of acculturation (language-based Hispanicism and Americanism, cultural identity, familism), acculturative stress, and alcohol or drug use, controlling for age and gender. 391 adult (18-44 years old) Latinx immigrants (69% women) completed measures on past 6-month behavior in Spanish or English. Results showed that Americanism was related to alcohol use severity, heavy episodic drinking, drug use severity, and any drug use. Acculturative stress was related to alcohol use severity, drug use severity, and any drug use, but not heavy episodic drinking. Familism was inversely related to drug use severity and any drug use, but not alcohol use severity or heavy episodic drinking. Cultural identity and Hispanicism were not related to alcohol or drug use. Consistent with previous research, a language-based measure of acculturation to the U.S. (Americanism) and acculturative stress were related to alcohol and drug use. Incremental validity of a multidimensional acculturation approach was limited. Intervention adaptations for Latinx immigrants should address stress reduction and mitigating adoption of receiving cultural practices.

ELSA 2018 Cohort: Protective Behavioral Strategies as Mediators of the Relationship between Risk Factors and Alcohol Outcomes in Argentinean College Freshmen

AIMS

The present study examined which types of alcohol protective behavioral strategies ([PBSs], Manner of Drinking [MOD] strategies, Serious Harm Reduction [SHR] or Limiting/Stopping Drinking strategies [LSD]) mediate the effects of a comprehensive number of distal antecedents on alcohol drinking quantity and alcohol-related negative consequences.

METHODS

A sample of 762 last-month college freshman drinkers from Argentina (Mean age = 19.60 ± 3.80) completed a survey that assessed alcohol outcomes (drinking quantity during a typical week and alcohol-related negative consequences), frequency of use of PBS and a set of distal antecedents (i.e. age at drinking onset, drinking motives, college alcohol beliefs and impulsivity-like traits).

RESULTS

MOD significantly mediated the effects of college alcohol beliefs (higher beliefs were associated with lower MOD use) and coping motives (higher coping motives were associated with lower MOD use) on alcohol outcomes. SHR significantly mediated the effects of sex (women reported more frequent SHR use) and enhancement motives (higher motivation was associated with lower SHR use) on alcohol-related negative consequences.

CONCLUSION

Our findings partially support a mediational role of PBS in the association between risk factors and alcohol outcomes, and offer valuable information for the design of interventions to reduce alcohol use in South-American college students. More studies examining PBS as mediators of distal antecedents are needed to fully understand the peculiarities of these associations in different cultures.
