How Strong is the "Fake ID Effect?" An Examination Using Propensity Score Matching in Two Samples

Where do heavy drinking college students experience alcohol consequences and where are they perceived to be normative?

High levels of alcohol consumption are common among college students and associated with endorsing negative alcohol-related consequences. Research suggests both drinking norms and location are strong predictors of drinking behavior in college students. Yet, normative perceptions of consequences, and whether they are location-specific, are less well-studied. We tested the hypotheses that college students who drink would have the highest levels of descriptive and injunctive norms for negative consequences, and would self-report the greatest number of negative consequences, at large gatherings/parties relative to someone's home/dorm and/or bars/clubs. Additionally, we explored whether specific acute consequences were more likely in some drinking locations versus others. Participants were 96 full-time undergraduate students who engaged in high-risk drinking. At baseline, participants reported descriptive and injunctive norms for negative consequences in three locations (home/dorm, large gathering/party, bar/club). Over a 28-day period, participants self-reported daily experiences of five alcohol-related consequences in these same locations. With repeated measures analyses of variance, we found that participants perceived their peers experienced more negative consequences and were more approving of negative consequences at large gatherings/parties and small gatherings at someone's home/dorm relative to bars/clubs. Likewise, nonparametric analyses demonstrated that the total number of consequences over the 28-day assessment period also differed by location, with participants reporting more consequences at home/dorm and large gathering/party locations than at bars/clubs. Future research is needed to better understand how the impact of norms on behavior differs across drinking location, and whether location-specific intervention content (e.g., normative correction) would be useful.

Investigating sensation seeking as a predictor of false identification attainment and associated risks among a college student sample

BACKGROUND

To date, few studies have included false identification (fake ID) use as a specific health risk behavior despite the fact that research has established a link between fake ID attainment and problematic alcohol use in a college student sample. The present study investigated the role of risk seeking, a facet of sensation seeking, in fake ID attainment, and the relation between fake ID attainment and risk seeking in predicting problematic drinking.

METHODS

Data were collected using a cross-sectional survey battery from a sample of college students at a large, Colorado university. Analyses included penalized likelihood and negative binomial regression models.

RESULTS

and Conclusions: Risk seeking positively predicted fake ID attainment. Additionally, a negative binomial hurdle model established that, controlling for 30-day alcohol use, both fake ID attainment and risk seeking predicted being drunk in the past 30 days. The role of risk seeking and fake ID attainment in problematic drinking outcomes is important to consider for informing prevention and intervention efforts in a college student population.

Online Peers and Offline Highs: An Examination of Online Peer Groups, Social Media Homophily, and Substance Use

Research indicates that youths are particularly susceptible to peer influence and that identifying with substance using peer groups predicts substance use. Today, youth spend more time interacting with distal peer groups via the Internet and have increased access to online drug cultures. Theoretically, this should have important implications for substance use. This study employs a nationally representative sample of U.S. youth (n = 1212), ages 15-25 years old, to examine whether online peer group identification and social media homophily predict substance use. Results indicate that online belonging and social media homophily are associated with some forms of substance use. While these factors were not significantly associated with regular marijuana or alcohol use among those who had initiated use, they predicted regular stimulant and opioid use among substance users. This suggests that online peer groups may promote progression into more problematic forms of substance use. Additional analyses of adolescent and young adult subgroups revealed important similarities and differences among the groups. The findings imply several directions for future research, and suggest that prevention policies and programs should continue to consider the role of online peers, and the Internet generally, in substance use initiation, escalation, and prevention.

Exposure to alcohol outlets, alcohol access, and alcohol consumption among adolescents

BACKGROUND

Adolescents who live near more alcohol outlets tend to consume more alcohol, despite laws prohibiting alcohol purchases for people aged <21 years. We examined relationships between adolescents' exposure to alcohol outlets, the sources through which they access alcohol, and their alcohol consumption.

METHODS

Participants for this longitudinal study (n = 168) were aged 15-18 years and were from 10 cities in the San Francisco Bay Area. We collected survey data to measure participant characteristics, followed by 1 month of GPS tracking to measure exposure to alcohol outlets (separated into exposures near home and away from home for bars, restaurants, and off-premise outlets). A follow-up survey approximately 1 year later measured alcohol access (through outlets, family members, peers aged <21 years, peers aged ≥21 years) and alcohol consumption (e.g. count of drinking days in last 30). Generalized structural equation models related exposure to alcohol outlets, alcohol access, and alcohol consumption.

RESULTS

Exposure to bars and off-premise outlets near home was positively associated with accessing alcohol from peers aged <21, and in turn, accessing alcohol from peers aged <21 was positively associated with alcohol consumption. There was no direct association between exposure to alcohol outlets near home or away from home and alcohol consumption.

CONCLUSIONS

Interventions that reduce adolescents' access through peers aged <21 may reduce adolescents' alcohol consumption.

Urban and Rural Adolescents' Points-of-Access for Alcohol and Tobacco

The purpose of this study was to examine alcohol and tobacco access points among a sample of rural and urban youth. Through collaboration with four regional school districts, a local drug prevention coalition administered a survey to a sample of 445 youth representing 30 different communities in a central U.S. region. The survey items included demographics, 30-day use measures, and questions about points-of-access for alcohol and tobacco. Results showed no differences among points-of-access between urban and rural youth. Ability to obtain alcohol from family, peers, other non-peer youth, and other non-family adults (P < 0.05) were each statistically significant predictors of 30-day alcohol use. Ability to obtain tobacco from family, peers, other non-peer youth, other non-family adults, and self-purchase (P < 0.05) were statistically significant predictors of 30-day tobacco use. Access through peers was the strongest predictor for both 30-day alcohol and tobacco use. Determining the primary social points-of-access youth use to obtain alcohol and tobacco can assist in the development of appropriate community-level prevention strategies and policies.
