TV, Social Media, and College Students' Binge Drinking Intentions: Moderated Mediation Models

Anxiety connects social media use to food and alcohol disturbance and disordered eating when social support is low

Food and alcohol disturbance (FAD) is an understudied form of disordered eating, in which the consumption of calories is restricted in preparation for drinking alcohol. Guided by previous literature, the present study examined the direct, indirect, and interactive relationships between social media use, anxiety, social support, FAD, and disordered eating among young adults. Recruited from a large southwestern public university, the sample included 679 undergraduate students who completed an online survey in spring of 2022 and who indicated that they consume alcohol and are 18 to 29 years old. Two moderated mediation analyses assessed the indirect effects of anxiety on the relationships between social media use with FAD and disordered eating, and the conditional contribution of social support. Results indicated that social media use was related to disordered eating both directly and indirectly through anxiety, but it was only related to FAD through anxiety. Furthermore, indirect effects connecting social media use to FAD and disordered eating were conditional upon social support. Our findings suggest FAD and disordered eating may be coping mechanisms for anxiety stemming from social media exposure, though these associations appear to be attenuated when social support is high. As such, these findings may be relevant for shaping future intervention and prevention efforts for emerging adults experiencing FAD and disordered eating.

Social identity and health-related behavior: A systematic review and meta-analysis

This paper examined the relationship between social identity and health-related behavior, exploring whether social identities are associated with multiple health-related behaviors or only specific ones, and whether this association varies on the type of social identity, the type of social identity measures or the expected relationship between identity and behavior. In a systematic review and meta-analysis we assessed whether the pattern of findings can be explained by the social identity approach. An extensive literature search was conducted in several databases including EBSCO-host and PubMed, using elaborate search terms related to social identity and health-related behavior. This resulted in 10728 potential articles, with 115 articles (with 248 effect sizes from 133 independent samples, N = 112.112) included in the meta-analysis. We found a small but positive overall association between social identification and health-related behavior, which was present for actual behavior, as well as for intention and attitudes. This association was stronger for health-related social identities, positive health-related behaviors, when the expected relationship was positive and when indirect social identity measures were used. However, not all findings could be explained by the social identity approach, indicating a need for further research to better understand the relationship between social identity and health-related behavior, in order to more effectively incorporate social identity into health interventions.

A systematic review and meta-analysis of the relationship between youth drinking, self-posting of alcohol use and other social media engagement (2012-21)

BACKGROUND AND AIM

Social networking sites (SNS) are interactive internet-based social platforms that facilitate information sharing. A growing body of literature on exposure to, and self-posting of, alcohol-related content on SNS has examined the relationship between SNS use and alcohol consumption in young people. This study aims to synthesise the literature exploring the relationship between exposure (i.e. viewing or listening of alcohol-related media) and self-posting (i.e. uploading images or text of alcohol content) of alcohol-related media on SNS on alcohol consumption.

METHODS

A pre-registered systematic review was conducted in June 2022 within PubMed, Scopus, PsycINFO and Web of Science. Original prospective and cross-sectional studies assessing youth and young adults (≤ 24 years of age) that measured exposure to alcohol-related media or posting of alcohol-related content on SNS and self-reported alcohol consumption outcomes were included. Meta-analyses were conducted on comparable methodologies.

RESULTS

Thirty studies were included (n = 19,386). Meta-analyses of cross-sectional studies showed both greater exposure (five studies; pooled β = 0.34, 95% confidence interval [CI] = 0.23, 0.44, i2 = 27.7%) and self-posting of alcohol-related content (six studies; pooled β = 0.57, 95%CI = 0.25,0.88, i2 = 97.8%) was associated with greater alcohol consumption. Meta-analyses of three prospective studies also identified that greater exposure predicted greater future alcohol consumption (three studies; pooled β = 0.13, 95%CI = 0.11,0.15, i2 = 0.0%). Narrative analyses of studies that could not be meta-analysed due to incompatible methodologies were also conducted. Most studies (all four prospective, one of two cross-sectional) identified positive associations between exposure to alcohol-related content and greater average consumption. Most studies (three of four prospective, four of six cross-sectional) reported a positive association between of alcohol-related self-posting and greater average alcohol consumption.

CONCLUSIONS

Both exposure to, and self-posting of, alcohol-related content on social networking sites are positively associated with current average consumption, problem drinking, and drinking frequency.

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.

"Follow my Finsta": Drinking trajectories in relation to auxiliary Instagram accounts

OBJECTIVE

This study explored the burgeoning youth practice of possessing a fake, secondary Instagram account known as a "Finsta" in relation to exposure to alcohol-related content and college drinking.

PARTICIPANTS

First-year university students with at least a primary Instagram account (N = 296) completed online surveys.

METHOD

Surveys assessed whether participants did or did not have a Finsta pre-matriculation (T1), Instagram alcohol content exposure one month into college (T2), and alcohol use at T1 and near the end of the first year (T3).

RESULTS

Moderated mediation analysis revealed that having a Finsta at T1 was associated with greater exposure to alcohol-related posts at T2 and, for male but not female students, predicted heavier drinking at T3.

CONCLUSION

Findings are consistent with previous results suggesting that males may be more behaviorally impacted by peers' depictions of alcohol use on social media. This carries implications for social media-based intervention efforts targeting first-year students.

Information Scanning Impacts Nonmedical Drug Use Among College Students: A Longitudinal Study of Scanning Effects

Health information that is acquired through information scanning has been shown to play an important role in shaping individual beliefs and health behavior. This study examines the direct and indirect effects of the breadth of scanning from media and interpersonal sources about two risk behaviors (nonmedical use of amphetamines and marijuana) on subsequent drug use behavior through changes to perceived norms. We test effects of scanning using a longitudinal online survey design with data collected at six-month intervals over three time points among 800 Israeli undergraduate students in their freshman year. Of the 800 respondents who participated in the first wave, 62.4% completed the second wave (N = 499), among which 347 (69.5%) completed a follow-up 6 months later. Results of cross-lagged structural equation models find that scanning information about amphetamines from interpersonal sources at 6 months predicted an increased likelihood of nonmedical use of amphetamines at 12-months. In addition, young adults who scanned information about marijuana from media sources at 6 months reported greater nonmedical marijuana use at 12 months. Breadth of scanning about marijuana from media sources mediated the relationship between perceived norms and marijuana use at 12 months. Results also showed indirect effects of scanning at baseline on nonmedical drug use at 12 months through scanning from the same source at 6 months. These findings contribute to our understanding of the role of information scanning and perceived norms in shaping substance use behaviors, and suggest that scanning may serve as a potential early indicator of risk.

How Do Social Network Sites Influence Workout Intentions: A Social Norm Approach

People share their workout experiences on social network sites (SNSs). The present study examined how perceived exposure to these workout-related SNS posts may affect individuals' engagement in physical activities through perceived descriptive and injunctive norms of workout in their network, and how self-efficacy in workout moderated the effect of perceived descriptive norm on their workout intention, which was measured in general and specific ways. An online survey was conducted with a convenience sample of 807 responses in China. Results show that perceived descriptive norm of workout in one's network mediated the relationship between perceived exposure to workout-related SNS posts and perceived injunctive norm. In addition, self-efficacy in workout moderated the effect of perceived descriptive norm on workout intention-both general and specific-but the normative influence was stronger at a low level of self-efficacy compared to a high level. Furthermore, perceived injunctive norm only predicted the general rather than specific workout intention, suggesting that the perception of most people's approval might not be priority when people consider details about workout. These findings develop the theory of normative social behavior by illustrating the relationship between perceived descriptive and injunctive norm and shed light on the relative strength of the motivating factors of workout in different situations.

An examination of the prospective associations between objectively assessed exposure to alcohol-related Instagram content, alcohol-specific cognitions, and first-year college drinking

Previous research suggests that exposure to alcohol-related content on social media sites (SMSs) may inflate perceptions of drinking norms, thereby increasing drinking among college students and potentially undermining popular social norms-based alcohol interventions. However, prior research on exposure has used subjective measures of alcohol exposure and has focused mostly on Facebook. The current study focused on Instagram, a popular SMS among college students, and utilized objective time tracking and newsfeed sampling methods to rigorously examine the prospective relationship between exposure to alcohol-related Instagram content (ARIC), alcohol cognitions, and drinking. Participants were 309 matriculating college students (Mage = 18.1, SD = 0.26; 62.1% female; 46.9% White/Caucasian; 17.5% Hispanic) who had their Instagram use tracked and newsfeeds sampled via a macro several times during the transition into college (August & September), and completed a baseline survey and two follow-up surveys. A sequential mediation model examined theoretically derived pathways between objective ARIC exposure and alcohol use. Results revealed that objective ARIC exposure during the transition to college was positively associated with drinking at the end of the first year of college, and subjective frequency of ARIC exposure mediated this relationship between objective ARIC exposure and later drinking. Subjective frequency of ARIC exposure also mediated the association between objective ARIC exposure and perceptions of descriptive norms, which, in turn, predicted later drinking. These findings illustrate that greater objective ARIC exposure during the transition into college may increase risky drinking over the first year via increased subjective frequency of ARIC and elevated perceptions of drinking norms. Priority directions for future research are discussed and several novel ways in which social norms-based interventions for first-year students may be enhanced to better combat ARIC-related influences are introduced.

Psychological Processes Underlying Effects of Alcohol Marketing on Youth Drinking

Objective:

Evidence increasingly suggests that alcohol marketing plays a significant role in facilitating underage drinking. This article presents a review of empirical studies and relevant theoretical models proposing plausible psychological mechanisms or processes responsible for associations between alcohol-related marketing and youth drinking.

Method:

We review key psychological processes pertaining to cognitive mechanisms and social cognitive models that operate at the individual or intrapersonal level (attitude formation, expectancies) and the social or interpersonal level (personal identity, social identity, social norms). We use dominant psychological and media theories to support our statements of putative causal inferences, including the Message Interpretation Processing Model, Prototype Willingness Model, and Reinforcing Spirals Model.

Results:

Based on the evidence, we propose an integrated conceptual model that depicts relevant psychological processes as they work together in a complex chain of influence, and we highlight those constructs that have received the greatest support in the literature.

Conclusions:

The evidence to date suggests that perceptions of others’ behaviors and attitudes in relation to alcohol (social norms) may be a more potent driver of youth drinking than evaluations of drinking outcomes (expectancies). Considerably more research—especially experimental research—is needed to understand the extent to which theoretically relevant psychological processes have unique effects on adolescent and young adult drinking behavior, with the ultimate goal of identifying modifiable intervention targets to produce reductions in the initiation and maintenance of underage alcohol use.

Self-reported campus alcohol policy and college alcohol consumption: a multilevel analysis of 4592 Korean students from 82 colleges

BACKGROUND

Campus alcohol policy has been associated with student alcohol consumption in numerous studies. However, more information is required to assess the extent to which school policy affects student drinking behavior; especially when both individual-level sociodemographic characteristics of students and area-level characteristics of college campuses are controlled for. Thus, this paper explores the association between campus alcohol policy and student alcohol consumption among a nationally representative sample of college students in South Korea, while controlling for both individual and area-level characteristics.

METHODS

We surveyed and analyzed the data of 4592 students from 82 colleges. Multilevel (hierarchical) linear modeling was used to identify the association between campus alcohol policy and alcohol consumption levels, measured via the AUDIT-C (Alcohol Use Disorders Identification Test - Consumption). Controlled individual-level characteristics included sex, year level, major, GPA (grade point average), pocket money, smoking status, stress level, depressive thoughts, suicidal thoughts, and number of clubs/organizations. Controlled area-level characteristics included college type, number of students, number of faculty members, number of workers/administrators, and region.

RESULTS

Compared to students unaware of their school's campus alcohol policy, students who self-reported that their campuses allow drinking in outdoor spaces (β = 0.755 p = 0.010) or in all areas (β = 0.820, p = 0.044) had higher AUDIT-C scores. Students attending schools with a large number of students, males, freshmen, students with low GPA, students with high amounts of pocket money, and smokers also had higher alcohol consumption scores relative to their peers. Alcohol education experience in the form of lectures, mail, and/or campaigns were not associated with student alcohol consumption levels.

CONCLUSION

Our results suggest an association between self-reported campus alcohol policy and student alcohol consumption. College educators and administrators must be aware that relative to students unaware of their school's campus alcohol policy, students at colleges that allow drinking in outdoor spaces or all areas consume higher amounts of alcohol than their peers; even when area-level factors are controlled for.

Breadth of Media Scanning Leads to Vaping among Youth and Young Adults: Evidence of Direct and Indirect Pathways from a National Longitudinal Survey

Electronic cigarette use among youth and young adults has reached an epidemic proportion of growth. This study examined the direct and indirect effects of the breadth of media scanning about e-cigarette use on subsequent vaping behavior through interpersonal communication and changes in descriptive norm perceptions. We conducted a nationally representative longitudinal phone survey of 13- to 25-year-olds from June 2014 to March 2017, with 11,013 respondents who completed a baseline survey, among which 3,212 completed a follow-up 6 months later. The results from both cross-sectional and lagged analyses provided robust evidence to suggest that passive routine exposure to e-cigarette use content from more media outlets predicted increased likelihood of vaping among youth and young adults. High scanners were about twice as likely to vape as non-scanners (17% versus 9%). Mediation models using bootstrapping procedures found that breadth of scanning predicted higher descriptive norm perceptions which were associated with subsequent vaping; in addition, interpersonal communication mediated the relationship between breadth of scanning and changes in descriptive norm perceptions. These findings highlight the important roles of scanning, norm perceptions and interpersonal discussions in shaping cognition and behavior changes. The results also suggest an overall pro-e-cigarette public communication environment, which warrants further examination.

Influence of Norm-Based Messages on College Students' Binge Drinking Intentions: Considering Norm Type, Regulatory Mode, and Level of Alcohol Consumption

This study examined the influence of norm-based messages on U.S. college students' binge drinking intentions, focusing on norm type, locomotion and assessment regulatory modes, and level of alcohol consumption as possible moderators. Results of an online experiment (N = 519) revealed significant three-way interactions among regulatory mode (assessment/locomotion), level of alcohol consumption, and norm type (i.e., descriptive vs. injunctive norms) on binge drinking intentions. The relative persuasiveness of descriptive vs. injunctive norm-based messages was contingent upon an individual's locomotion/assessment regulatory mode and overall alcohol consumption level. Findings from this study extend research on social norms and regulatory mode and provide useful suggestions for the norm-based college drinking intervention.

Social Drinking on Social Media: Content Analysis of the Social Aspects of Alcohol-Related Posts on Facebook and Instagram

Background

Alcohol is often consumed in social contexts. An emerging social context in which alcohol is becoming increasingly apparent is social media. More and more young people display alcohol-related posts on social networking sites such as Facebook and Instagram.

Objective

Considering the importance of the social aspects of alcohol consumption and social media use, this study investigated the social content of alcohol posts (ie, the evaluative social context and presence of people) and social processes (ie, the posting of and reactions to posts) involved with alcohol posts on social networking sites.

Methods

Participants (N=192; mean age 20.64, SD 4.68 years, 132 women and 54 men) gave researchers access to their Facebook and/or Instagram profiles, and an extensive content analysis of these profiles was conducted. Coders were trained and then coded all screenshotted timelines in terms of evaluative social context, presence of people, and reactions to post.

Results

Alcohol posts of youth frequently depict alcohol in a positive social context (425/438, 97.0%) and display people holding drinks (277/412, 67.2%). In addition, alcohol posts were more often placed on participants’ timelines by others (tagging; 238/439, 54.2%) than posted by participants themselves (201/439, 45.8%). Furthermore, it was revealed that such social posts received more likes (mean 35.50, SD 26.39) and comments than nonsocial posts (no people visible; mean 10.34, SD 13.19, P<.001).

Conclusions

In terms of content and processes, alcohol posts on social media are social in nature and a part of young people’s everyday social lives. Interventions aiming to decrease alcohol posts should therefore focus on the broad social context of individuals in which posting about alcohol takes place. Potential intervention strategies could involve making young people aware that when they post about social gatherings in which alcohol is visible and tag others, it may have unintended negative consequences and should be avoided.
