Identifying Distinct Patterns of Social Media Usage During the Transition into College as Predictors of First-Year Alcohol Use and Consequences: A Latent Profile Analysis

Social media (SM) users are a combination of several behaviors across platforms. Patterns of SM use across platforms may be a better indicator of risky drinking than individual behaviors or sets of behaviors examined previously. This longitudinal study addressed this gap in the literature using latent profile analysis (LPA) to identify subpopulations of SM users during the college transition (N=319). Indicators included in the LPA were general SM (checking, time spent, and posting to Instagram/Facebook/Snapchat; Finstagram ownership) and alcohol-related posting (alcohol, partying, and marijuana content) behaviors. LPA results revealed three SM user subpopulations at baseline: low general use with low alcohol-related posting (LGU+LAP), and high general use with low alcohol-related posting (HGU+LAP) or high alcohol-related posting (HGU+HAP). Baseline drinking, injunctive norms, and alcohol beliefs were associated with greater odds of HGU+HAP membership. Prospective analyses revealed that HGU+HAP was associated with greater alcohol use and consequences relative to HGU+LAP and LGU+LAP. Results suggest that there are distinct patterns of SM use during the college transition associated with risky drinking that can inform interventions combating SM-related alcohol risks. These findings also illustrate the importance of analyzing multiple SM user behaviors across multiple platforms simultaneously in future studies.

The influence of multidimensional deprivation on problem drinking developmental trajectory among young adults: a longitudinal study using latent class growth analysis

Background Many young people in Korea today experience deprivation in various areas of life. The social determinants of health approach maintains that social factors play an important role in an individual’s physical and mental health. This study aimed to investigate the problem drinking trajectory of young Korean people and identify the effects of multidimensional deprivation on problem drinking. Methods The study used data from 2012 to 2018 found in the Korea Welfare Panel Study. Latent class growth analysis was performed to determine the number of trajectories of problem drinking. After identifying latent classes, a multinomial logistic regression analysis was utilized to examine multidimensional deprivation as a predictor of class membership. Results Latent class analysis yielded three groups: (1) a low-level maintenance group (low level of alcohol use maintained at the low level), (2) a moderate-level increasing group (moderate level of problem drinking with a moderate increase in problem drinking), and (3) a risky drinking increasing group (high level of problem drinking with a rapid increase in problem drinking). Results from multinomial logistic regression showed that deprivation in housing and social deprivation increased the probability of belonging to the risky drinking increasing group compared to other reference groups. Conclusion The study speaks to the need to establish appropriate intervention strategies according to the level and changes in the pattern of alcohol use. The implications of housing and social deprivation concerning problem drinking among young Korean people are also discussed.

A Randomized Controlled Trial of the Prevent Alcohol and Risk-Related Trauma in Youth Program in Reducing Alcohol-Related Harms in Young Naval Trainees

ABSTRACT Background The aim of this study was to test whether participation in an alcohol risk reduction program known as Prevent Alcohol and Risk-Related Trauma in Youth (P.A.R.T.Y.) is effective in reducing the prevalence of risky drinking at 12 months’ post-intervention in a sample of Royal Australian Navy (RAN) trainees. Methods A non-blinded randomized controlled trial of 952 RAN trainees comparing two forms of P.A.R.T.Y. plus RAN annual alcohol and other drug awareness training with annual alcohol and other drugs awareness training only (Control). Participants were screened at baseline and at 12-month follow-up using the Alcohol Use Disorders Identification Test (AUDIT). Participants were randomized to one of three arms: (1) in-hospital P.A.R.T.Y program, (2) on-base P.A.R.T.Y. program, or (3) control. The primary outcome measure was the percentage of participants reporting an AUDIT score of 8 or above at 12 months in each group. A secondary outcome considered was reports of alcohol-related incidents in the 12-month follow-up. Results There was no difference in the risk of reporting an AUDIT score of 8 or above in either the in-hospital (Relative Risk (RR) 0.96, 95% CI: 0.75-1.23; P = .75) or on-base (RR 1.11, 95% CI: 0.89-1.369; P = 0.35) intervention groups, compared to the control group. Compared to the on-base group, there was no difference in the risk of reporting an AUDIT score of 8 or above in the in-hospital group (RR 1.16, 95% CI: 0.90-1.48; P = .24). The rate of reporting an alcohol-related incident was not different for the in-hospital (Hazard Ratio (HR) 0.60, 95% CI: 0.27-1.33; P = .21) or on-base (HR 0.50, 95% CI: 0.21-1.16; P = .11) intervention groups when compared to the control group. Conclusion Participation in either an on-base or an in-hospital P.A.R.T.Y. program did not affect the proportion of naval trainee participants screening positive for risky drinking on the AUDIT.

Irregular Autonomic Modulation Predicts Risky Drinking and Altered Ventromedial Prefrontal Cortex Response to Stress in Alcohol Use Disorder

Aims Autonomic dysfunction has been associated with risky drinking and alcohol use disorder (AUD). Although autonomic nervous system (ANS) activity has been attributed to the ventromedial prefrontal cortex (VmPFC)-limbic-striatal regions, the specific role of ANS disruption in AUD and its association with these regions remain unclear. Using functional magnetic resonance imaging (fMRI) and concurrent electrocardiogram (ECG), the current study examined neural correlates of ANS activity in AUD and its role in AUD pathology. Methods Demographically matched 20 AUD patients and 20 social drinkers (SD) completed an fMRI task involving repeated exposure to stress, alcohol-cue and neutral-relaxing images in a block design. Based on the known VmPFC-limbic-striatal functions involved in emotions, reward and the ANS, we performed a regions of interest (ROI) analysis to examine the associations between ANS activity and neural responses in the VmPFC, amygdala, and ventral striatum. Results Across conditions, AUD patients showed significantly higher levels of overall heart rate (HR) and approximate entropy (ApEn) compared to SD (Ps < 0.05). In all participants, increased HR was associated with greater drinking volume (P < 0.05). In addition, higher ApEn levels were associated with greater drinking volume (P < 0.05) and decreased right VmPFC response to stress (P < 0.05). Discussion Our findings demonstrate ANS disruption in AUD indexed by high overall HR and ApEn. The association between ApEn and rVmPFC response suggests that ApEn may play a role in modulating drinking via interactions with neural regions of emotion regulation. These findings provide insight into patterns of ANS disruption and their relevance to AUD pathology.

Dingle & Han 2021 The Effect of COVID-19 on Australian University Students' Mental Health

This is a summary report of survey data from two cohorts of first year university students at a metropolitan university in Australia: 2019 (i.e., pre-COVID-19) and in 2020 (during the first wave of COVID-19). The results show clear detrimental impact of COVID-19 on multiple measures of stress, mental health and wellbeing, loneliness. The only measure that did not worsen was risky drinking. A sense of belonging to the university and the use of coping strategies were associated with better mental health.

Think-aloud testing of a novel safer drinking app for college students during COVID-19 (Preprint)

BACKGROUND Hazardous alcohol consumption, and binge drinking in particular, continues to be common among college students, posing the greatestrisk for their health and safety. Despite widespread exposure to evidence-based preventive interventions among U.S. undergraduates, only modest and temporary effects on risky drinking occur. Formative studies have demonstrated that students want a more engaging intervention tool for risky drinking that can be used “just in time.” OBJECTIVE The purpose of this study was to test the appeal, relevance, and perceived utility of a draft mobile app for safer student drinking. METHODS Undergraduate student participants tested the draft mobile app via an interactive online prototype with hot spots that responded to their taps to mimic app functionality. They narrated their impressions, navigation, and comments in a standardized Think-Aloud procedure. After each round of Think-aloud interviews, researchers debriefed the investigators and developers to discuss findings and brainstorm app modifications. RESULTS Data indicated that minor changes to the functionality and aesthetics would improve usability of the app. Student testers recommended tailoring the app to the needs of college students and to aspects of the local university’s drinking culture. CONCLUSIONS Findings from this study will be synthesized with information gained from other formative work to determine the final app features. We will test the app in a pilot randomized trial to assess app usage and the impact of the app on college student drinking behavior over several months.
