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.

Affective factors explaining the association between depressive functioning and alcohol outcomes among college students.

Rates of co-occurring depression and alcohol use are higher among college students than in the general population. Further research is needed to illuminate how the mechanisms with which individuals process negative emotions may clarify the link between depressive symptoms and drinking. Objective: To assess how three potential mediators representing affective functioning (ie, need for affect, distress tolerance, emotion regulation) explain the relationship between depressive symptoms and alcohol use (ie, quantity and problems). Participants: The sample consisted of 227 college student heavy drinkers. Methods: Participants completed computerized self-report surveys in Fall 2016. Results: Path analyses revealed need for affect mediated the association between depressive symptoms and alcohol quantity, while emotion regulation mediated the relationship between depressive symptoms and alcohol-related problems. Conclusions: Findings highlight the importance of various affective functioning mechanisms to the depressive symptom-drinking link. Future research could target these mechanisms in college interventions for co-occurring mood symptoms and alcohol use.

Testing Daily Associations between Impulsivity, Affect, and Alcohol Outcomes: A Pilot Study.

BACKGROUND: Considerable research has examined impulsivity between individuals, but less research has focused on whether impulsivity fluctuates within a person. Although previous research supports trait levels of impulsivity as a risk factor for increased alcohol involvement, it is unclear whether daily (i.e., state) fluctuations in impulsivity coincide with same-day drinking behaviors. The present pilot study tested (1) the extent to which impulsivity fluctuates within-person; (2) the influence of daily impulsivity on alcohol use outcomes across all days (i.e., whether drinking occurred, the number of drinks consumed, and intentions to drink) and on drinking days only (i.e., whether heavy episodic drinking occurred and the number of problems experienced); and (3) daily affect as moderators of these relationships. METHOD: Participants were 24 young adult drinkers without postsecondary education who completed a baseline plus 14 follow-up daily surveys. Each day, participants reported their impulsivity, affect, and drinking behavior. RESULTS: Multilevel modeling revealed that 42.5% of the variability in daily impulsivity was due to within-person differences. Impulsivity was related to greater odds of heavy episodic drinking and more alcohol-related problems on drinking days. Positive affect moderated the relationship between impulsivity and alcohol-related problems, and the relationship between impulsivity and drinking intentions. CONCLUSIONS: Findings suggest that changes in positive affect and impulsivity may be a risk factor for alcohol problems in a daily context. Future research examining within-person impulsivity and negative outcomes may benefit from considering positive affect.

The Influence of a Brief Alcohol Intervention on Alcohol Use Trajectories in Nonstudent Emerging Adult Drinkers.

Background: This study sought to inform research with noncollege-attending emerging adults, an at-risk, and understudied population, by identifying patterns of response following a brief alcohol intervention. This study was a reanalysis of data from a randomized controlled intervention trial testing a brief, personalized feedback alcohol intervention targeting nonstudent emerging adult drinkers. Objectives: The study aims were to (1) model intervention response by identifying subgroups characterized by changes in heavy drinking (i.e. peak use, number of binges during a typical week, proportion of binge days, peak estimated blood alcohol concentration [eBAC]) following the alcohol intervention, and (2) distinguish subgroups on factors related to intervention response (i.e. perceived norms regarding how much peers drink, alcohol use severity, mental health symptoms, and readiness to change). Methods: Participants were 81 (64.2% men) nonstudent heavy drinkers between ages 18-25 years (average age = 22.04) recruited from the community. Results: Findings revealed two latent subgroups that exhibited differential response to the intervention (i.e. intervention "responders" and "nonresponders"). Further, responders reported higher pre-intervention descriptive normative perceptions and alcohol use severity. Conclusions/Importance: The current investigation contributed to knowledge regarding for whom brief alcohol interventions work in the short term within nonstudent emerging adults and could inform future research to facilitate behavior change in those unresponsive to intervention efforts.

An Examination of the Most Recent Episode of Molly Use among College Students.

OBJECTIVE: The current study examined event-level characteristics (e.g., contextual factors, risk behaviors) during the most recent episode of Molly use among a sample of college students who reported previously using Molly. PARTICIPANTS: Participants (N = 151; 66.7% female) were drinkers aged 18 to 25. Data were collected from October to November 2014, February to April 2015, and September to November 2015. METHOD: Participants completed measures regarding typical Molly use and items related to context and behaviors during their most recent episode of Molly use. RESULTS: Findings revealed that our sample most commonly reported using Molly earlier in the evening while hanging out with friends or at a party. Additionally, sexual and other drug use behaviors commonly occurred when using Molly. CONCLUSIONS: Findings provide preliminary information in guiding future work exploring Molly use and potential substance-related issues associated with the context of when and how Molly is consumed.
