Changes in Parent-Student Text Message and Phone Call Communication During the Transition to College as Predictors of Cannabis and Simultaneous Use During the First Year.

Parent communication can be protective against cannabis use among young adults. However, changes in parent-student communication frequency naturally occur during the transition from high school to college. Recent research suggests declines in parent-student communication frequency predict increased drinking and consequences during the first year of college, yet these effects on other risky behaviors are unknown. The current study investigated whether post-matriculation changes in frequency of texting/calling with parents predict cannabis use and simultaneous use of cannabis and alcohol, and whether pre-matriculation cannabis and simultaneous use predict changes in communication. First-year students (N = 287, 61.3% female, 50.9% White) reported cannabis and simultaneous use pre- and post-matriculation (T1 & T3) and changes in frequency of texting/calling their mother/father per day (T2). Negative binomial hurdle models examined whether T2 changes in communication frequency predicted T3 cannabis and simultaneous use, and logistic regression models examined whether T1 cannabis and simultaneous use predicted T2 changes in communication frequency. Results revealed that increasing (vs. decreasing) frequency of calling with mothers and texting with fathers was protective against cannabis use, whereas increasing frequency of calling with fathers was associated with greater risk of use. Changes in communication did not significantly predict simultaneous use, nor did pre-matriculation cannabis or simultaneous use predict changes in either mode of communication with parents during the college transition. These findings highlight that changes in mother and father communication may be both beneficial and detrimental to cannabis use depending on the parent and mode of communication. Implications for these findings are discussed.

Process Evaluation and Investigation of Cultural Adaptations for an Online Parent-Based Intervention Using a Mixed-Method Approach.

Most alcohol intervention research focuses on program efficacy, yet few studies have investigated the acceptability of a program's design and implementation to the target population or adapting existing alcohol interventions to different populations. To address these gaps in the literature, we (1) examined participant responsiveness to and implementation quality of FITSTART+, a web-app delivered parent-based alcohol intervention designed for incoming first-year college students in the United States, and (2) gathered feedback on how this intervention could be adapted to other populations of parents. A sample of U.S. parents of 17-20-year-old first-year college students (N = 109) participated in FITSTART+ during their child's first year of college and completed a survey about parents' responsiveness to the app and its quality. Next, a sample of non-U.S. parents of adolescents aged 13 to 19 (N = 44) participated in one of 11 focus groups in which they briefly explored the app and then discussed how it could be adapted to be applicable and culturally relevant for them and their context. Results revealed that U.S. parents rated the intervention's quality as high and parents were responsive to the web-app's content, but some did not visit one of the most critical aspects of the intervention (i.e., alcohol-related parenting resources). Non-U.S. participants provided a range of suggestions for adapting the intervention to their context, which varied by culture. Results identify areas for improvement, particularly regarding the use of alcohol-related parenting resources, in this intervention and for web-delivered PBIs more broadly.

Text Messages Conveying Parent Drinking Limits: A Potential Avenue for Preventing and Reducing Alcohol Use in College Students.

OBJECTIVE: Although previous research has established that students who perceive that their parents have lower drinking limits consume less alcohol, optimal approaches for effectively communicating these limits are less understood. To address this gap in the literature, the present study examined the effects of hypothetical limit-focused text messages on estimated drinking behavior. METHOD: Undergraduate college students (N=253) completed an online survey in which they were instructed to imagine a scenario where they were planning to go out at night to an event involving drinking. Participants were randomly assigned to a condition where they would receive one of four hypothetical text messages from their mother and/or father containing a range of drinking limits. They were then asked to report how much alcohol they would realistically consume on this night if they were and were not obligated to check in with their parent at the end of the night. RESULTS: Hypothetical text messages from mothers and fathers containing lower drinking limits resulted in lower estimated alcohol consumption. A drinking limit of zero resulted in the least amount of expected alcohol consumption but specifying 1-2 drinks as a limit might produce a similar effect if parents also required their student to check-in at the end of the night. CONCLUSION: Findings from this study provide initial support for future studies to investigate the effects of limit setting text messages sent from parents on college student drinking, as well as the effects of text messages sent from parents requiring that students check-in.

Effects of the FITSTART + PBI on drinking and negative alcohol-related consequences during the first year of college.

Objective: This study evaluated FITSTART+, a parent-based intervention (PBI), for preventing risky drinking among first-year college students. Participants: Participants were traditional first-year students aged between 17 and 20. Method: In total, 391 eligible students completed a baseline survey and their parents were then invited to use the FITSTART+ PBI or Control web-applications. 266 students had a parent who created a profile in the app (FITSTART+ PBI, n = 134; FITSTART+ Control, n = 132). Additionally, 58 parents randomized to the FITSTART+ PBI did not complete the personalized normative feedback (PNF) component of the intervention. Results: No significant effect on drinking or related consequences was detected between Intervention and Control groups. However, exploratory analyses revealed that completing PNF in the FITSTART+ PBI condition was associated with a greater likelihood of remaining zero on consequences at follow-ups. Conclusion: The PNF component of the FITSTART+ PBI showed potential in preventing risky drinking, warranting further research.

Do Changes in Parent-Student Phone Call and Text Message Communication During the Transition to College Predict First-Year Drinking and Consequences? A Prospective Study.

OBJECTIVE: We examined (a) whether changes in parent-student phone call and text messaging communication during the transition into college are associated with alcohol use and related consequences, and (b) whether pre-matriculation drinking patterns predicted these changes in parent-student communication. METHOD: First-year students (n = 246; M age [SD] = 17.91 [0.39] years; 61.8% female) participated in a longitudinal survey study as a part of a larger study. Before matriculation (Time 0), participants reported their drinking and whether they experienced alcohol consequences in the past 30 days. Approximately 1 month into their first semester (Time 1), participants reported if the frequency of their calling and texting their parents had decreased, remained the same, or increased since the start of college. Drinking and consequences were then reassessed 4 months later (Time 2). Analytic models evaluated (a) whether a decrease in calling and texting parents, as reported by students (compared with an increase or no change), predicted drinking outcomes, and (b) whether pre-college drinking (compared with nondrinking) predicted changes in communication. RESULTS: Changes in phone calls and texting with mothers and fathers during the first month of college predicted alcohol use and consequences into the second semester. In addition, heavy drinking predicted lower odds of texting frequency with mothers staying the same or increasing. CONCLUSIONS: This study underscores that consistent call or text communication with students during their transition into college could serve as a protective factor against alcohol risk. By closely monitoring such communication, parents may be better equipped to identify potential signs of risky drinking behavior in their first-year students.

An examination of the associations between depressive symptoms, perceived parental discipline, alcohol use, and drinking-related consequences during the first year of college: A moderated mediation model.

Background: Depression is prevalent among adolescents and young adults and is associated with experiencing increased negative alcohol-related consequences; thus, it is imperative to identify malleable protective factors for alcohol risks in young adults experiencing elevated depressive symptoms. The current study longitudinally explored the effects of perceived parental alcohol-related discipline on the relationship between depressive symptoms, alcohol use, and negative drinking consequences during the transition into college. Methods: Incoming college students (N = 272, 63.2% female) completed web-based surveys before (July, T1) and after (October, T2) the transition into college and reported depressive symptoms, perceived alcohol-related discipline, alcohol use, and consequences of drinking experienced in the past 30 days. Results: The moderated mediation model revealed that at above average perceptions of alcohol-related discipline, depressive symptoms were negatively associated with alcohol use, which in turn was associated with experiencing fewer negative consequences of drinking. Limitations: The current study did not measure a diagnosis of major depressive disorder, and therefore our results may differ among clinical populations. In addition, we did not measure other parenting constructs shown to protect students with elevated levels of depressive symptoms from experiencing consequences (i.e., monitoring). Conclusions: The present findings suggest perceptions of parental alcohol-related discipline measured here (e.g., having a privilege taken away, being scolded or grounded) can be protective against alcohol risks among college students experiencing above average depressive symptoms. Parent-based alcohol interventions administered prior to matriculation should encourage parents of depressed students to clearly communicate consequences for drinking to their child.

"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.

Capturing the bigger picture: A gestalt of general and alcohol-specific social media usage during the transition to college as a predictor of first-year alcohol use and consequences.

Previous research has shown a reliable association between social media (SM) use and drinking among college students. However, most studies have investigated SM behaviors (e.g., time spent on a platform, posting frequency) in isolation and on a single site. While some have studied multiple SM behaviors across platforms using person-centered approaches (e.g., latent profile analysis [LPA]), these studies have failed to take alcohol-related SM behaviors into account. This longitudinal study addressed this gap in the literature by using LPA to identify subpopulations of SM users during the college transition (N = 319; 62.1% female) using general (frequency of checking, time spent on, and frequency of posting to Instagram/Facebook/Snapchat; Finstagram ownership) and alcohol-related SM behaviors (posting alcohol, partying, and marijuana content). LPA results revealed three SM user profiles at baseline: low general use with low alcohol-related posting (LGU + LAP), high general use with low alcohol-related posting (HGU + LAP), and high general use with high alcohol-related posting (HGU + HAP). Prospective analyses revealed that HGU + HAP membership was associated with greater descriptive peer drinking norms, alcohol use, and consequences relative to HGU + LAP and LGU + LAP membership. Results suggest that there are distinct patterns of general and alcohol-related SM use during the college transition associated with risky drinking that can inform interventions combating SM-related alcohol risks. These findings illustrate the importance of investigating SM use holistically and suggests studying alcohol-related SM behaviors may reveal differences in individuals' alcohol risk that general SM behaviors might not capture.

Taking alcohol from one's parents' home without permission as a risk factor for greater alcohol and marijuana use during the transition into college.

While adolescents and underage emerging adults typically obtain alcohol from social sources (e.g., parents, friends, parties), taking alcohol from the home without permission is not well understood. The current study investigated plausible individual characteristics associated with taking alcohol from one's parents' home without permission and associations between taking alcohol and drinking, alcohol consequences, and marijuana use. Two cohorts of alcohol-experienced underage emerging adults (N = 562) completed a web-based survey pre-college matriculation. Participants reported sources of alcohol (friend, mother, father, party, took it from home); drinking; consequences; marijuana use (ever and past 30 days); age of alcohol initiation; symptoms of depression, anxiety, and stress; parental modeling of drinking; and demographic information. Results revealed that taking alcohol was significantly associated with several of the measures examined here (e.g., having obtained alcohol from friends, parents, and parties; earlier age of alcohol initiation; parental modeling of alcohol). Having taken alcohol from the home without permission and obtained it from friends were uniquely associated with increased odds of typical weekly drinking, consequences, and marijuana use in the past 30 days when controlling for all other variables assessed in this study (including drinking, in the consequences and marijuana models). Parent-based interventions targeting adolescents and emerging adults should inform parents of the risks associated with taking alcohol from the home and obtaining it from friends. Further, parents should also be informed that supplying their adolescent with alcohol or modeling drinking may increase the likelihood that they take alcohol from their home.

Systematic Bias in Self-Reported Social Media Use in the Age of Platform Swinging: Implications for Studying Social Media Use in Relation to Adolescent Health Behavior.

Public health researchers are increasingly interested in the potential relationships between social media (SM) use, well-being, and health behavior among adolescents. However, most research has assessed daily SM time via self-report survey questions, despite a lack of clarity around the accuracy of such reports given the current tendency of youth to access SM on multiple electronic devices and cycle between multiple SM platforms on a daily basis (i.e., platform swinging). The current study investigates the potential for systematic reporting biases to skew findings. Three hundred and twenty incoming college students downloaded software on their computers, tablets, and smartphones to track their active use of Facebook, Twitter, Instagram, and Snapchat over a 2-week surveillance period and then self-reported their average daily minutes on each platform immediately after. Larger proportions of students over-estimated than under-estimated their use, with the largest overestimations found on the most heavily used platforms. Females logged significantly more SM time and were less accurate in reporting than were males and, independently, the likelihood of substantial inaccuracies in reporting total SM time and time on most individual platforms increased with each additional SM platform participants reported using. Findings demonstrate that self-reported estimates of SM time among adolescents in the age of SM platform swinging are prone to substantial error and may lead to biased conclusions about relationships between variables. Alternative measurement approaches are suggested to improve the validity of future research in this area.

Exposure to interpersonal stigma enhances the effectiveness of a culturally adapted personalized normative feedback alcohol intervention for sexual minority women.

Stigma-related stress and inflated perceptions of substance use norms are positioned in the literature as theoretically distinct explanations for disproportionate substance use among sexual minorities. As research has yet to examine how these variables may interact in an intervention context, this study examined the impact of recent experiences with violence and harassment due to sexual minority status (i.e., interpersonal stigma exposure) on the effectiveness of a culturally adapted personalized normative feedback intervention for lesbian, bisexual, and queer (LBQ) women. A sub-sample of 499 moderate-to-heavy drinking LBQ women were randomized to receive personalized normative feedback (PNF) on alcohol use or control topics within a broader digital competition designed to challenge negative LBQ stereotypes. At baseline, recent interpersonal stigma exposure strengthened the relationship between perceived LBQ alcohol-related norms and participants' own alcohol-related behaviors (i.e., consumption and consequences). At follow-up, 3 months later, recent interpersonal stigma exposure moderated the effectiveness of alcohol PNF with substantially less drinking and consequences among participants in the treatment condition reporting recent violence or harassment due to sexual minority status, relative to those reporting no such experiences. Underscoring the utility of PNF for LBQ women and potentially other heavy drinking stigmatized populations, findings suggest that a greater tendency to conform to over-estimated ingroup drinking norms may be another way in which minority status-based violence and harassment contributes to alcohol consumption in stigmatized populations.

Evaluating Non-response Bias in a Parent-Based College Alcohol Intervention.

Background: The purpose of this study was to address a dearth in the literature on non-response bias in parent-based interventions (PBIs) by investigating parenting constructs that might be associated with whether a parent volunteers to participate in a no-incentive college drinking PBI. Method: Incoming first-year students (N = 386) completed an online questionnaire that included items assessing plausible predictors of participation in a PBI (students' drinking, perceptions of parents' harm-reduction and zero-tolerance alcohol communication, whether parents allowed alcohol, and changes in parents' alcohol rules). Four months later, all parents of first-year students at the study university were invited to join the PBI, which was described as a resource guide to teach them how to help their student navigate the college transition and prepare them for life at their university. Results: Parents who signed up for the intervention used greater harm-reduction communication than those who did not sign up, were more likely to have allowed alcohol use, and signing up was significantly associated with student reports that fathers became less strict toward drinking after high school. Students' drinking and zero-tolerance communication did not significantly differ between the groups. Conclusion: Results indicate that non-response bias can be an issue when utilizing a real-world, non-RCT recruitment approach to invite parents into a PBI (i.e., non-incentivized, inviting all parents). Findings suggest that more comprehensive recruitment strategies may be required to increase parent diversity in PBIs.

A Gamified Personalized Normative Feedback App to Reduce Drinking Among Sexual Minority Women: Randomized Controlled Trial and Feasibility Study.

BACKGROUND: Sexual minority women disproportionately engage in heavy drinking and shoulder the burden of alcohol dependence. Although several intensive interventions are being developed to meet the needs of treatment-seeking sexual minority women, there remains a lack of preventive interventions to reduce drinking and its consequences among women not yet motivated to reduce their alcohol consumption. OBJECTIVE: We aimed to examine the feasibility and efficacy of reducing alcohol-related risks via personalized normative feedback (PNF) on alcohol use and coping delivered within LezParlay, a social media-inspired digital competition designed to challenge negative stereotypes about lesbian, bisexual, and queer (LBQ)-identified sexual minority women. METHODS: Feasibility was assessed by examining engagement with LezParlay outside the context of an incentivized research study, assessing the characteristics of the LBQ women taking part, and examining the competition's ability to derive risk-reducing actual norms as well as levels of acceptability and perceived benefits reported by participants. Intervention efficacy was examined by randomizing a subsample of 499 LBQ alcohol consumers (ie, drinkers) already taking part in the competition to receive sexual identity-specific PNF on alcohol use and coping, alcohol use only, or control topics over only 2 rounds of play. Changes in alcohol use and negative consequences were examined 2 and 4 months after the delivery of treatment PNF. RESULTS: A total of 2667 diverse LBQ women played ≥1 round of LezParlay. The competition attracted large numbers of moderate and heavy drinkers; however, risk-reducing actual norms could still be derived from competition rounds and featured in PNF. Efficacy results revealed that drinkers who received PNF on alcohol use and both alcohol use and coping had similar reductions in their weekly drinks (P=.003; P<.001), peak drinks (P<.001; P<.001), and negative consequences (P<.001; P<.001) relative to those who received PNF on control topics at the 2-month follow-up. However, at the 4-month follow-up, reductions in alcohol consumption outcomes faded among those who received alcohol PNF only (weekly: P=.06; peak: P=.11), whereas they remained relatively robust among those who received PNF on both alcohol use and coping (weekly: P=.02; peak: P=.03). Finally, participants found the competition highly acceptable and psychologically beneficial as a whole. CONCLUSIONS: The LezParlay competition was found to be a feasible and efficacious means of reducing alcohol-related risks in this population. Our findings demonstrate the utility of correcting sexual identity-specific drinking and coping norms to reduce alcohol-related risks among LBQ women and suggest that this approach may also prove fruitful in other stigmatized health disparity populations. To engage these populations in the real world and expand the psychological benefits associated with PNF, our findings also point to packaging PNF within a broader, culturally tailored competition designed to challenge negative group stereotypes.

Do the effects of parent-based alcohol interventions depend on college residence? A short communication.

Parent-based interventions (PBIs) and living at home with one's parents both have been shown to mitigate alcohol risk associated with the first year of college. The current study extends these findings by examining the independent and interactive effects of these two constructs on first-year drinking. The sample included 82 parent-student dyads. Parents were randomized to receive an online PBI that either did (intervention; n = 44) or did not (n = 38) include alcohol-related content in December 2020. Students completed online surveys assessing college residence and drinking (typical weekly and peak) in August 2020 (T1) and February 2021 (T2). Hierarchical zero-inflated Poisson models assessed the main and interaction effects of having a parent in the intervention group (vs control) and living with parents (vs without) on drinking outcomes, controlling for T1 alcohol use. Results revealed that living with parents predicted decreases in typical weekly drinking and having a parent in the intervention predicted decreases in the number of drinks consumed on one's peak drinking occasion at T2. Treatment*residence was also significantly associated with typical weekly drinking in the inflated model. These results suggest that moving out was associated with a greater likelihood of not drinking during a typical week if students had a parent in the intervention and a lower likelihood of not drinking during a typical week if they had a parent in the control application. Together, findings support continued exploration of this online PBI as it appears to reduce peak drinking during the first year of college and reduces the odds of students drinking during a typical week when they move out of their parents' home.

Integrating social media inspired features into a personalized normative feedback intervention combats social media-based alcohol influence.

BACKROUND: Research suggests that the social media platforms popular on college campuses may reflect, reinforce, and even exacerbate heavy drinking practices among students. The present study was designed to directly examine: (1) whether exposure to alcohol-related content on social media diminishes the efficacy of a traditional web-based personalized normative feedback (PNF) alcohol intervention among first-year drinkers; and (2) if social media inspired features and digital game mechanics can be integrated into a PNF intervention to combat social media-based alcohol influence and increase efficacy. METHOD: Alcohol experienced first-year college students (N = 223) completed a pre-survey that assessed exposure to alcohol-related content and social media and were randomized to 1 of 3 web-based alcohol PNF conditions (traditional, gamified only, or social media inspired gamified). One month later, participants' alcohol consumption was reassessed. RESULTS: Among participants who received traditional PNF, social media-based alcohol exposure interacted with pre-intervention drinking such that traditional PNF was less effective in reducing drinking among heavier drinkers reporting greater exposure to alcohol-related social media content. Further, when regression models compared the efficacy of all three conditions, the social media inspired gamified PNF condition was significantly more effective in reducing drinking than was traditional PNF among moderate and heavy drinkers reporting greater exposure to alcohol on social media. CONCLUSION: Although additional research is needed, these findings suggest that representing the population of students on whom normative statistics are based with social media-like user avatars and profiles may enhance the degree to which alcohol PNF is relatable and believable among high-risk students.

Prospective Relationships Between Objectively Assessed Social Media Use, Drinking Norms, and Alcohol Consumption Among First-Year Students.

OBJECTIVE: Previous research has linked social media involvement and alcohol use among college students. However, this literature has been limited by self-report measures of social media use, cross-sectional data, inadequate attention to potential moderators and mediators, and unclear implications for interventions. To improve and extend this work, students' (N = 297) daily time on Facebook, Twitter, Instagram, and Snapchat during the transition into college were assessed objectively and examined as predictors of later drinking. METHOD: Time spent on social media overall and on each individual platform between August and September were examined as predictors of alcohol consumption in March. Perceptions of peer drinking norms in October were examined as a potential mediator of these relationships, and sex as a potential moderator. RESULTS: Students spent the most daily time on Snapchat, followed by Instagram. The results indicated that among men, but not women, daily social media time during the transition into college predicted second semester drinking. This relationship was mediated by perceptions of same-sex student drinking norms. Analysis of individual platforms revealed that daily time on Snapchat drove the relationships among men. CONCLUSIONS: Greater time on social media during the transition to college, and on Snapchat in particular, predicted increases in perceptions of peer drinking norms and, in turn, greater alcohol consumption among men only. These findings carry precise implications for interventions seeking to reduce alcohol-related risks among first-year men and underscore the need for additional research examining developmental factors and social media user experiences that may explain the sex-specific patterns of relationships observed.

A Gamified, Social Media-Inspired, Web-Based Personalized Normative Feedback Alcohol Intervention for Lesbian, Bisexual, and Queer-Identified Women: Protocol for a Hybrid Trial.

BACKGROUND: Sexual minority women are more likely to drink alcohol, engage in heavy drinking, and experience alcohol-related problems than heterosexual women. However, culturally tailored interventions for this population have been slow to emerge. OBJECTIVE: This type 1 effectiveness-implementation trial examines the feasibility and efficacy of a gamified, culturally tailored, personalized normative feedback (PNF) alcohol intervention for sexual minority women who psychologically identify as lesbian, bisexual, or queer (LBQ). METHODS: The core components of a PNF intervention were delivered within LezParlay, a fun, social media-inspired, digital competition designed to challenge negative stereotypes about LBQ women and increase visibility. The competition was advertised on the web through social media platforms and collaboration with LBQ community organizations. After 2 rounds of play by a large cohort of LBQ women, a subsample of 500 drinkers already taking part in the competition were invited to participate in the evaluation study. Study participants were randomized to receive 1 of 3 unique sequences of PNF (ie, alcohol and stigma coping, alcohol and control, or control topics only) over 2 intervention rounds. Randomization was fully automated by the web app, and both researchers and participants were blinded. RESULTS: Analyses will evaluate whether PNF on alcohol use reduces participants' drinking and negative consequences at 2 and 4 months postintervention; examine whether providing PNF on stigma-coping behaviors, in addition to alcohol use, further reduces alcohol use and consequences beyond PNF on alcohol alone; identify mediators and moderators of intervention efficacy; and examine broader LezParlay app engagement, acceptability, and perceived benefits. CONCLUSIONS: This incognito intervention approach is uniquely oriented toward engaging and preventing alcohol-related risks among community populations of LBQ women who may view their heavy drinking as normative and not in need of change because of the visibility of alcohol use in sexual minority community spaces. Thus, this intervention strategy diverges from, and is intended to complement, more intensive programs being developed to meet the needs of LBQ women already motivated to reduce their consumption.

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.

Normative Substance Use Antecedents among Sexual Minorities: A Scoping Review and Synthesis.

Although sexual minority stress remains the dominant perspective for understanding disproportionate substance use among lesbian, gay and bisexual (LGB) populations, social norms are among the most predictive and commonly targeted substance use antecedents in other high-risk groups. This scoping review seeks to bring clarity to the body of norms-focused alcohol, tobacco, and other drug (ATOD) research conducted with LGBs over the past 20 years, identify intervention implications, and present priority directions for future research. Fifty-two peer-reviewed studies published between June 1999 and June 2019 were identified from searches of PubMed, PsycInfo, and Medline databases using combinations of terms related to: social norms; sexual orientation or sexual minority status; and, the use of alcohol, tobacco, and other drugs. A far greater number of studies focused on actual ATOD norms than perceived ATOD norms or discrepancies between actual or perceived norms, illuminating the need for additional research focused on these levels of analysis. Taken together, this literature suggests that: (1) perceived ATOD norms are reliable predictors of LGBs' ATOD use; (2) actual ATOD use norms are low among LGBs participating in representative, population-based survey studies; and, (3) LGBs over-estimate the ATOD use of peers. Thus, intervention strategies including personalized normative feedback, psychoeducation, and social branding may hold promise in reducing LGBs substance use. However, additional research is needed to increase our understanding of injunctive ATOD norms, identify meaningful LGB reference groups, elucidate environmental influences on ATOD norms, and examine relationships between stigma experiences, perceived norms, and ATOD use.

Lesbians' use of popular social media sites is associated with perceived drinking norms & interest in receiving personalized normative feedback on alcohol use.

Alcohol-related problems disproportionately impact sexual minority women. Recent research suggests that lesbian-identified women overestimate peer drinking norms and therefore, personalized normative feedback (PNF) may be an appropriate and efficacious intervention strategy for reducing alcohol-related risks in this population. To inform the development and packaging of such interventions, this study examines lesbians' use of the popular social media sites Facebook, Instagram, Snapchat, and Twitter in relation to alcohol consumption, perceptions of peer drinking norms, confidence in normative perceptions, and interest in receiving alcohol PNF. Findings suggest that the lesbians who are most likely to benefit from a PNF alcohol intervention may also be the most readily reached via social media sites. Alcohol interventions that both recruit and deliver PNF via widely used social media platforms such as Facebook and Instagram represent a promising and cost-effective strategy to reduce heavy drinking among lesbians.
