Are all alcohol and energy drink users the same? Examining individual variation in relation to alcohol mixed with energy drink use, risky drinking, and consequences.

Individuals who consume alcohol mixed with energy drinks (AmEDs) have been identified as higher-risk drinkers, as they are more prone to drink increased amounts of alcohol and experience more consequences compared with non-AmED users. The present study examined differential AmED use and alcohol consumption simultaneously as multidimensional risk behaviors among AmED users. Students who identified as drinkers and current AmED users (n = 195) completed a Web-based survey related to their AmED consumption and typical drinking patterns. Latent profile analysis was used to classify participants into distinct AmED user profiles. Profiles were then compared on AmED-based cognitive factors (e.g., expectancies, norms) and alcohol-related consequences. Four AmED user profiles emerged: moderate drinker, low proportion AmED users (ML); heavy drinker, low proportion AmED users (HL); moderate drinker, high proportion AmED users (MH); and heavy drinker, high proportion AmED users (HH). Membership in higher-proportion AmED groups was associated with more positive AmED expectancies and perceived norms. No significant differences were observed in the amount of consequences endorsed by HL and HHs; however, MHs experienced significantly more alcohol-related physical consequences than MLs. This suggests that increased use of AmEDs is associated with increased risk of experiencing alcohol-related consequences for moderate drinkers. Screening students for AmED use could be used as a novel, inexpensive tool to identify high-risk drinkers for targeted interventions aimed at reducing alcohol consumption and related problems.

Judging cheaters: is substance misuse viewed similarly in the athletic and academic domains?

The present study examines how individuals judge others who use performance-enhancing drugs in two different domains--the athletic domain and the academic domain. Approximately 1,200 males in their freshman year of college completed a questionnaire that included two scenarios. One scenario described an athlete who misused anabolic steroids to help him succeed at a sporting event. The other described a college student who misused Adderall to help him succeed on his midterm exams. Participants rated the extent to which they thought the target had cheated and the extent to which they felt the substances were necessary for success. Results showed participants believed the athlete was more of a cheater than the student, and this difference got larger as past prescription stimulant misuse increased. Results also demonstrated that participants felt Adderall was more necessary than anabolic steroids for bringing about success. Contributions to the literature on zero-sum and non-zero-sum domains are discussed. Implications for future research and efforts to prevent substance misuse are described.

One-time or repeat offenders? An examination of the patterns of alcohol-related consequences experienced by college students across the freshman year

Recent studies have examined alcohol-related consequences in college students as an independent outcome variable, rather than as a result of heavy drinking. The present study examined the patterns of consequences experienced by first-year college students (n=169). Specifically, the number of distinct consequences and the frequency of repeated consequences were evaluated as well as the combination of the two. Results revealed that 80% of participants reported experiencing multiple consequences, with over 34% of students reporting 6 or more unique consequences over the course of their freshmen year. In addition, nearly 50% of the sample reported experiencing 3 or more consequences repeatedly. Further, 23% of the sample reported experiencing 5 or more repeated consequences and 6 or more multiple consequences. These individuals experienced 38% of the multiple consequences and 54% of the repeated consequences reported by the entire sample, suggesting individuals who endorsed experiencing multiple consequences repeatedly also experienced a disproportionate number of the total consequences reported by the sample. The findings suggest there are specific high-risk patterns of alcohol-related consequences and demonstrate a need for further examination of additional variables that predict consequences.

Examining the relationship between alcohol-energy drink risk profiles and high-risk drinking behaviors.

BACKGROUND The mixing of alcohol and energy drinks (AMEDs) is a trend among college students associated with higher rates of heavy episodic drinking and negative alcohol-related consequences. The goals of this study were to take a person-centered approach to identify distinct risk profiles of college students based on AMED-specific constructs (expectancies, attitudes, and norms) and examine longitudinal associations between AMED use, drinking, and consequences. METHODS A random sample of incoming freshmen (n = 387, 59% female) completed measures of AMED use, AMED-specific expectancies, attitudes, and normative beliefs, and drinking quantity and alcohol-related consequences. Data were collected at 2 occasions: spring semester of freshmen year and fall semester of sophomore year. RESULTS Latent profile analysis identified 4 subgroups of individuals: occasional AMED, anti-AMED, pro-AMED, and strong peer influence. Individuals in the pro-AMED group reported the most AMED use, drinking, and consequences. There was a unique association between profile membership and AMED use, even after controlling for drinking. CONCLUSIONS Findings highlighted the importance of AMED-specific expectancies, attitudes, and norms. The unique association between AMED risk profiles and AMED use suggests AMED use is a distinct behavior that could be targeted by AMED-specific messages included in existing brief interventions for alcohol use.

Sexual-orientation differences in drinking patterns and use of drinking contexts among college students

BACKGROUND Evidence suggests there are important sexual-orientation differences in alcohol consumption, particularly among women. Little is known about where gay/lesbian and bisexual college students drink or differences in drinking patterns derived from graduated frequency measures between heterosexual, gay/lesbian, and bisexual students. The goal of this analysis was to examine patterns of alcohol consumption-including drinking prevalence, quantity, frequency, and contexts of use-by sexual orientation. METHODS Data on sexual identity, gender, drinking behaviors, and drinking contexts were examined from repeated cross-sectional samples of undergraduate students attending 14 public California universities from 2003-2011 (n=58,903). Multivariable statistical techniques were employed to examine sexual-orientation differences stratified by gender. RESULTS Gay males, lesbians, and bisexual females were significantly more likely to report drinking alcohol in the current semester than their same-gender heterosexual peers (relative risks ranged from 1.07 to 1.10, p-values <0.01). Among current drinkers, bisexual females consumed 7 or more drinks and lesbians consumed 10 or more drinks on significantly more days than heterosexual females. On the other hand, gay male drinkers consumed 8 or more drinks on significantly fewer days than heterosexual male drinkers. Compared to their same-gender heterosexual peers: lesbian/gay and bisexual students drank less frequently at Greek parties (incidence rate ratios [IRRs] ranged from 0.52 to 0.73, p-values <0.01); lesbians (IRR=0.84, p=0.043) and bisexual males (IRR=0.82, p=0.009) drank less frequently at off-campus parties; and gay males drank more frequently outdoors (IRR=1.63, p<0.001) and at bars/restaurants (IRR=1.21, p=0.013). CONCLUSIONS Alcohol prevention programs and future research should consider sexual-orientation differences in drinking patterns and use of drinking contexts.

Combining alcohol and energy drinks: An examination of psychosocial constructs and alcohol outcomes among college students using a longitudinal design

Combining alcohol and energy drinks (e.g., Red Bull and vodka) is a significant problem on college campuses. To date, few studies have examined psychosocial constructs specific to alcohol-energy drink cocktail (AmED) consumption that could be amenable to change via prevention efforts targeting this population. The aim of the current study was to examine differences in AmED-specific attitudes, beliefs, normative perceptions among students who report AmED use compared to college student drinkers who consume alcohol only. In addition, these two groups were compared on their intentions to consume AmEDs, actual AmED use, and other drinking outcomes using a longitudinal design. Participants (N  =  386, 59% female) completed a web-based survey in the spring of their first year of college and fall of their second year assessing alcohol-energy drink cocktail use, psychosocial decision-making constructs, heavy drinking, and alcohol-related consequences. Findings revealed that combiners of alcohol and energy drinks had more positive attitudes and beliefs about AmED use, higher perceived peer norms, and stronger intentions toward future use. Accordingly, at Time 2, this group reported significantly higher AmED use, along with high-risk drinking and related consequences. The findings reinforce that AmED use is associated with risky drinking practices, and suggest potential targets for change for future prevention efforts.

Do coaches make a difference off the field? The examination of athletic coach influence on early college student drinking

Coaches can exert a considerable influence on the lives of their athletes. However, little is known about the influence of athletic coaches on athlete drinking behaviors. This study extends research on drinking influences in student-athletes. The relationship between athletic coaches and athlete drinking behaviors were examined. First-year college students (N = 362) who had played high school sports were assessed on their relationships with their coaches as well as their alcohol use and problems. Findings revealed significant associations among the approval of and relationship with their athletic coaches and student drinking behaviors. These findings are discussed in the context of involving coaches in comprehensive strategies to reduce athlete drinking.

A Critical Assessment of Bias in Survey Studies Using Location-Based Sampling to Recruit Patrons in Bars

Location-based sampling is a method to obtain samples of people within ecological contexts relevant to specific public health outcomes. Random selection increases generalizability; however, in some circumstances (such as surveying bar patrons), recruitment conditions increase risks of sample bias. We attempted to recruit representative samples of bars and patrons in six California cities, but low response rates precluded meaningful analysis. A systematic review of 24 similar studies revealed that none addressed the key shortcomings of our study. We recommend steps to improve studies that use location-based sampling: (i) purposively sample places of interest, (ii) use recruitment strategies appropriate to the environment, and (iii) provide full information on response rates at all levels of sampling.

The Role of Drinking Beliefs to Explain Ethnic Variation in Drinking Practices Among U.S. College Students

This study, funded by the National Institute on Alcohol Abuse and Alcoholism, examines psychosocial mediators to explain discrepancies in past-30-day drinking between African American and White college student drinkers in the United States. Between 2008 and 2010, 5,845 college drinkers completed an online survey about their alcohol use. Using latent variable structural equations modeling, we investigated the relationships between ethnicity, drinking beliefs, and students’ past 30-day alcohol use. Drinking beliefs—i.e., positive expectancies, perceived norms, and disapproval of alcohol use—fully mediated the relationship between ethnicity and drinking behaviors. Study limitations and directions for future research are discussed.

A brief report on Hispanic youth marijuana use: trends in substance abuse treatment admissions in the United States

ABSTRACT Increases in Hispanic youth admissions to substance abuse treatment programs for marijuana use are a growing public health concern. In this study, we investigated trends in Hispanic youth from 1995 to 2012 utilizing the Treatment Episode Data Set—Admissions of the Substance Abuse Mental Health Services Administration. Hispanic youth marijuana admissions are associated with youth 15–17 years old, in high school, and living in a dependent situation. Notably, female admissions increased at greater rates than males. Results also point to decreasing tolerance of minor marijuana use by schools and community agencies. Findings highlight the need for targeted, culturally specific, and cost-effective treatment and prevention efforts.
