Daily Positive Alcohol Expectancies and Alcohol Use Outcomes among College Students.

Expectancy theory supports alcohol expectancies, or the expected effects of drinking, as an important factor in alcohol use behaviors. Recent research supports that alcohol expectancies fluctuate daily, but scant research has examined specific types of expectancies and their associations with alcohol use at the daily level. Consequently, the present study examined (1) the daily association between select expectancies (i.e., sociability, tension reduction, liquid courage) and likelihood of drinking, and (2) whether daily expectancies predict alcohol use outcomes (i.e., alcohol-related problems, heavy drinking) on drinking days. Participants (N = 221; 79.2% women) were primarily White (48.4%) and Black (29.7%) university students. Participants completed daily measures of expectancies, alcohol use, and alcohol-related problems each day for 14 days. Results from multilevel models revealed daily sociability as the only expectancy subscale linked with increased odds of drinking. Daily expectancies did not predict heavy drinking or alcohol-related problems on drinking days. At the between-person level, average levels of sociability and tension reduction expectancies were associated with a greater likelihood of engaging in heavy drinking and experiencing a problem. Findings highlight that fluctuations in sociability expectancies may be proximally linked to likelihood of alcohol use, which may inform just-in-time intervention efforts targeting alcohol expectancies.

Normative Perceptions of Peer Drinking Distinguish High-Intensity Drinkers from Other Drinking Groups.

Background: High-intensity drinking (HID), or drinking that doubles the binge threshold (i.e., 8+/10+ drinks for women/men), is associated with more negative consequences than binge-only drinking. However, research focusing on HID and factors that may delineate HID from other drinking behaviors is lacking. The present study evaluated if perceived norms for peer drinking behavior (i.e., descriptive norms for alcohol quantity and frequency and injunctive norms) differentiated high-intensity drinkers from other drinker statuses. Further, we evaluated the role of perceived norms on odds of HID engagement and HID frequency. Finally, college status, sex, and underage drinker status were evaluated as moderators of the association between perceived norms and HID status/frequency. Methods: Participants were 623 emerging adult drinkers recruited via Craigslist (68.7% male; 69.0% White). Participants completed an online survey on their drinking behaviors and related social factors. Results: Each domain of perceived norms positively associated with drinker status. Higher perceived norms were associated with greater odds of HID and predicted HID frequency. The association between quantity and frequency descriptive norms and HID engagement was stronger for nonstudents and was only significant for males. Underage drinker status did not moderate associations between perceived norms and HID engagement. Conclusions: Findings provided evidence that perceptions of peer drinking behaviors are strong indicators of HID risk and may be especially useful for identifying high-intensity drinking males and nonstudents. The utility of perceived peer norms to differentiate this group of particularly risky drinkers suggests that social-influence-focused intervention approaches, including norms correction, may be efficacious in targeting HID among emerging adults.

The impact of the COVID-19 pandemic experiences on college drinking via mental distress: Cross-sectional mediation moderated by race.

BACKGROUND: The COVID-19 pandemic has been linked to stress, anxiety, and depression among college students, with heightened distress tied to greater drinking for some individuals. Emerging research suggests that these associations may differ across race, but few studies use adequate samples to examine this, particularly among college students, an at-risk population for both heavy drinking and mental distress. Specifically, pandemic-related stressors and mental distress may be higher among Black students than White students. The current study examined: (1) whether mental distress cross-sectionally mediates the association between pandemic-specific stressors and drinking and (2) whether race (Black or White) moderates these associations. METHODS: A cross-sectional online survey of 400 college drinkers (43% White, 28% Black) in fall 2020 assessed pandemic-related stressors (e.g., losing a job, contracting COVID-19, changed living situation), mental distress (stress, anxiety, depression), and drinking (past-month drinking, perceived changes since the start of the pandemic). RESULTS: Cross-sectional mediation models indicated that financial stressors and social distancing were linked to greater quantity and frequency of past-month drinking through greater mental distress. For perceived changes in drinking, only financial stressors were linked to drinking greater quantities and drinking more often (compared to pre-pandemic levels) via mental distress. Moderated mediation models among students identifying as White or Black revealed that changed living situation was a robust stressor across race. Financial stressors and social distancing were linked with greater distress only among White students, whereas essential worker status was a protective factor against distress only among Black students. CONCLUSIONS: Select stressors were linked to increased drinking through greater mental distress, with differential risks across Black versus White students. Findings suggest campus administrators should focus on connecting students with resources (e.g., counseling centers and health promotion offices) during times of distress.

Social network moderators of brief alcohol intervention impact.

OBJECTIVE: This investigation examined the impact of social networks on drinking reduction efforts following a brief alcohol intervention. In a reanalysis of data from an earlier randomized controlled trial with nonstudent emerging adult drinkers (Lau-Barraco et al., 2018), we aimed to test three domains of preintervention social network features as potential factors influencing intervention response: (a) general network characteristics (i.e., network size, network stability), (b) general network alcohol use (i.e., network alcohol abstainers, network heavy/problem drinkers), and (c) risky peers in network (i.e., proportion of drinking buddies, presence of drinking buddies identified as heavy/problem drinker). METHOD: Participants were 164 emerging adult heavy drinkers recruited from the community (65.9% men; mean age = 21.98 years; 56.2% ethnic minority). Participants were randomly assigned to either a brief personalized feedback intervention (PFI) or assessment-only control and provided data at 1-month and 3-month follow-ups. RESULTS: Greater network stability and greater representation of alcohol abstainers in one's social network were associated with improved initial postintervention response. Heavy/problem drinkers in the network did not moderate initial postintervention effects on drinking outcomes, but there was potentially a stronger intervention effect on risk reduction for those with higher proportions of drinking buddies in their network. CONCLUSIONS: Study findings provided evidence that a PFI was efficacious in mitigating some risky social network influence. However, findings did not support a consistent impact across all the network variables examined. Future research is needed to further clarify social network influences and how they may be targeted to enhance intervention efficacy. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
