Partying Before the Party: Examining Prepartying Behavior Among College Students

Objective: The authors examined the phenomenon known to college students as prepartying, which is the consumption of alcohol prior to attending an event or activity (eg, party, bar, concert) at which more alcohol may be consumed. Participants: To explore the extent of this behavior, the authors surveyed 227 college students about each drinking event over a 1-month period. Results: Principal results revealed that 64% of participants engaged in prepartying (75% of drinkers) and that prepartying is involved in approximately 45% of all drinking events. Prepartying was predictive of more drinking throughout the day of the drinking event and alcohol-related negative consequences. Men and women engaged in this behavior at similar rates, and prepartying was most related to social reasons for drinking. Conclusion: Because prepartying is well-known among students, the authors suggest that clinicians and researchers target it to better understand college drinking and to help students understand the associated dangers.

Effects of alcohol, expectancies, and partner type on condom use in college males: Event‐level analyses

Sexually active heterosexual college males (N = 93) provided data on over 1,500 sexual encounters. Alcohol consumption, expectancies about alcohols impact on condom use, and partner type each contributed to use of a condom. Partner type covaried with alcohol consumption and condom use. The men consumed significantly more alcohol with new partners, followed by casual partners, and then by regular partners. In contrast, they were more likely to use condoms with new partners than with casual or regular partners. Drinking alcohol decreased condom use, but only with casual partners. Expectancies about alcohols disinhibiting sexual effects decreased condom use as well. These data suggest that alcohol consumption does decrease condom use, particularly with casual partners and when drinkers believe alcohol alters sexual disinhibition. Improving knowledge about HIV and other STD transmission in casual partners and challenging expectancies about alcohol as a sexual disinhibitor could help decrease the spread of HIV and other STDs.

Live Interactive Group-Specific Normative Feedback Reduces Misperceptions and Drinking in College Students: A Randomized Cluster Trial

This research evaluated the efficacy of a live and interactive group-specific normative feedback intervention designed to correct misperceptions of alcohol-related group norms and subsequently reduce drinking behavior. Campus organizations (N = 20) containing 1,162 college students were randomly assigned to intervention or assessment-only control conditions. Participants in the intervention condition attended an intervention during their organizations regular standing meeting. Data were gathered in vivo using computerized handheld keypads into which participants entered personal responses to a series of alcohol-related questions assessing perceptions of normative group behavior as well as actual individual behavior. These data were then immediately presented in graphical form to illustrate discrepancies between perceived and actual behavioral group norms. Results indicated that compared with the control group, the intervention group reduced drinking behavior and misperceptions of group norms at 1-month and 2-month follow-ups. Changes in perceived norms mediated the reductions in drinking. Results demonstrate the effectiveness of a novel, technologically advanced, group-based, brief alcohol intervention that can be implemented with entire groups at relatively low cost.

Identifying Factors That Increase the Likelihood for Alcohol-Induced Blackouts in the Prepartying Context

The present study examined risk factors related to “blacking out” (e.g., temporary periods of memory loss during drinking) during preparty drinking events (i.e., pregaming, predrinking). Participants were students from two universities on the West Coast who reported past month prepartying (N = 2,546) in online surveys administered in the fall of 2008. Among these students, 25% (n = 636) reported blacking out during at least one occasion in which they prepartied in the past month. A logistic regression model underscored that Greek student affiliation, family history of alcohol abuse, frequency of prepartying, and both playing drinking games and consuming shots of liquor while prepartying increased the likelihood of blacking out. Limitations and implications for future research and collegiate prevention strategies are discussed.

Before You Slip into the Night, You'll Want Something to Drink: Exploring the Reasons for Prepartying Behavior Among College Student Drinkers

Prepartying among college students is an emerging topic of research and clinical focus. Unfortunately for some students, prepartying, or quick drinking before going out for the primary event of the evening, can lead to high blood alcohol levels, further drinking, and subsequent consequences. The present study was designed to explore the reasons for prepartying among a sample of 444 male and female students. Males and females reported arriving to a social event already under the influence, saving money, and making the night more interesting as their most highly endorsed reasons for prepartying. Males endorsed reasons relating to increased social and sexual facilitation with opposite sex peers to a greater extent than females. Although underage and legal drinking age participants did not differ in prepartying frequency or typical quantity, underage students reached higher estimated blood alcohol levels during prepartying. Finally, alcohol-related consequences were significantly and positively associated with nearly all reasons for prepartying for both men and women.

A brief Rutgers Alcohol Problem Index with less potential for bias

The Rutgers Alcohol Problem Index (RAPI), a popular measure of alcohol-related problems in adolescents, varies with many theoretically-relevant measures of individual differences, including sex. The sex differences in RAPI scores fit many models of alcohol problems but could also arise from biased items. In addition, a short form could increase the scales utility. The current study examined RAPI scores, an additional inventory of problem drinking, and measures of alcohol consumption in over 2000 college student drinkers. Analyses revealed items that functioned differentially for men and women. Dropping these items created a shorter scale with almost identical psychometric properties but less potential for bias. Correlations with drinking habits and drinking problems were the same as those for the full scale, and the size of the effect for the difference between men and womens responses remained essentially the same. These results confirm previous work using different analytic approaches, and suggest that a short form of the RAPI could prove helpful in future research. In addition, these data suggest that analyses of differential item functioning in other scales can reveal important information about the measurement of drug problems.

A Randomized Motivational Enhancement Prevention Group Reduces Drinking and Alcohol Consequences in First-Year College Women

Alcohol consumption among college students has become an increasing problem that requires attention from college administrators, staff, and researchers. Despite the physiological differences between men and women, college women are drinking at increasingly risky rates, placing them at increased risk for negative consequences. The current study tested a group motivational enhancement approach to the prevention of heavy drinking among 1st-year college women. Using a randomized design, the authors assigned participants either to a group that received a single-session motivational enhancement intervention to reduce risky drinking that focused partly on womens specific reasons for drinking (n = 126) or to an assessment-only control group (n = 94). Results indicated that, relative to the control group participants, intervention participants drank fewer drinks per week, drank fewer drinks at peak consumption events, and had fewer alcohol-related consequences over a 10-week follow-up. Further, the intervention, which targeted womens reasons for drinking, was more effective in reducing consumption for participants with high social and enhancement motivations for drinking.

A Group Motivational Interviewing Intervention Reduces Drinking and Alcohol-Related Consequences in Adjudicated College Students

This study examines the effectiveness of a single-session group motivational enhancement intervention with college students adjudicated for violation of alcohol policy. the intervention consisted of a timeline Followback assessment of drinking, social norms re-education, decisional balance for behavior change, relapse prevention, expectancy challenge, and the generation of behavioral goals. All participants evidenced significant reductions in drinking from baseline through one and three month follow-up. Male participants and frequent binge drinkers showed the largest and most sustained reductions in drinking behavior. the results of this study provide tentative evidence for the effectiveness of group motivational enhancement interventions with adjudicated students.

Using Facebook to Recruit Young Adult Veterans: Online Mental Health Research

Background Veteran research has primarily been conducted with clinical samples and those already involved in health care systems, but much is to be learned about veterans in the community. Facebook is a novel yet largely unexplored avenue for recruiting veteran participants for epidemiological and clinical studies. Objective In this study, we utilized Facebook to recruit a sample of young adult veterans for the first phase of an online alcohol intervention study. We describe the successful Facebook recruitment process, including data collection from over 1000 veteran participants in approximately 3 weeks, procedures to verify participation eligibility, and comparison of our sample with nationally available norms. Methods Participants were young adult veterans aged 18-34 recruited through Facebook as part of a large study to document normative drinking behavior among a large community sample of veterans. Facebook ads were targeted toward young veterans to collect information on demographics and military characteristics, health behaviors, mental health, and health care utilization. Results We obtained a sample of 1023 verified veteran participants over a period of 24 days for the advertising price of approximately US

7.05 per verified veteran participant. Our recruitment strategy yielded a sample similar to the US population of young adult veterans in most demographic areas except for race/ethnicity and previous branch of service, which when we weighted the sample on race/ethnicity and branch a sample better matched with the population data was obtained. The Facebook sample recruited veterans who were engaged in a variety of risky health behaviors such as binge drinking and marijuana use. One fourth of veterans had never since discharge been to an appointment for physical health care and about half had attended an appointment for service compensation review. Only half had attended any appointment for a mental health concern at any clinic or hospital. Despite more than half screening positive for current probable mental health disorders such as post-traumatic stress disorder, depression, anxiety, only about 1 in 3 received mental health care in the past year and only 1 in 50 received such care within the past month. Conclusions This work expands on the work of other studies that have examined clinical samples of veterans only and suggests Facebook can be an adequate method of obtaining samples of veterans in need of care.
