Individual-level interventions to reduce college student drinking: a meta-analytic review

Difficulties with positive, but not negative, emotion regulation moderate the association between positive alcohol expectancies and alcohol use in college students

Background

Positive alcohol expectancies are linked to increased alcohol use among college students. Difficulties regulating emotion have been shown to moderate this relationship, though little research accounts for differences based on the valence of the emotion being regulated.

Objective

To examine the independent moderating roles of positive and negative emotion dysregulation on the association between positive alcohol expectancies and alcohol use.

Methods

College students (N = 165, Mage = 20.48, SDage = 1.90; 66.1 % Female; 66.7 % White; 65.5 % non-Hispanic) who reported regular substance use (≥ 3 times in the past week) completed a one-time survey. Linear regression analyses with moderation were conducted.

Results

Correlational analyses suggested that positive alcohol expectancies, positive emotion dysregulation, and negative emotion dysregulation were positively associated with greater alcohol use. Linear regression analyses indicated that difficulties with positive emotion regulation moderated the relationship between positive alcohol expectancies and alcohol use. However, difficulties with negative emotion regulation did not moderate this relationship. College students who reported greater positive alcohol expectancies and concurrently greater difficulties with positive emotion regulation also report greater alcohol consumption, compared to those who reported greater positive alcohol expectancies and fewer difficulties regulating positive emotion.

Discussion

Difficulties with positive, not negative, emotion regulation may serve as a risk factor for hazardous alcohol use in college students. Findings may inform the modification of existing intervention programs across university counseling centers and other health sectors to promote the development of positive emotion regulation skills for individuals who endorse positive emotion regulation difficulties, thereby reducing hazardous alcohol use amid this high-risk developmental period.

The bystander intervention for problematic alcohol use model (BIPAUM)

Objective: The study aimed to identify phases of bystander intervention (BI) for problematic alcohol use (PAU) among college students. Participants: Twenty focus groups and nine interviews were conducted. Methods: Transcripts were thematically analyzed. Results: The phases of the Bystander Intervention for Problematic Alcohol Use Model (BIPAUM) include: (1) plan in advance, (2) notice and interpret a sign, (3) decide (i.e., assume responsibility, assess support/feasibility to intervene, and identify intervention strategy), (4) intervene, and (5) assess outcomes. Assessing outcomes loops to influence future behavior and each phase is influenced by barriers and facilitators. Conclusions: These unique phases should be considered when designing and evaluating intervention programs for PAU to meet students' needs and better reduce PAU. Future research should empirically test the BIPAUM. The results of the current study demonstrate a promising opportunity for applying BI to PAU, with the goal of reducing risky drinking among college students.

Prevalence of hazardous alcohol consumption and evaluation of associated factors in university students

PURPOSE

The aim of the study was to determine the prevalence of hazardous alcohol consumption (HAC) according to gender among university students and associated factors.

METHODS

This is a cross-sectional study conducted on undergraduate students. We used a stratified sampling technique to represent 26036 students from all grade levels and 11 faculties, and the survey was administered to 2349 undergraduate students. The prevalence of HAC was determined with the Alcohol Use Disorders Identification Test (AUDIT). HAC was defined as getting 8 points or more from the AUDIT. Multivariate logistic regression analyses were performed to examine HAC related factors in both genders.

RESULTS

In this study, 53.2% of the participants were male. The prevalence of HAC in the study group was 13.5% and prevalence of lifetime drinker was 65.3%. In males; those whose fathers [OR = 1.72; 95% CI: (1.17-2.52)], mothers [1.49; (1.02-2.18)], close friends [2.42; (1.28-4.60)] drink alcohol and smoking [3.16; (2.09- 4.77)], use illicit substance [2.35; (1.66-3.34)], have mental health problems [1.65; (1.04-2.62)] were more likely to report HAC. Meanwhile in females, those whose fathers [OR = 1.92; 95%CI: (1.03-3.57)], close friends [5.81; (1.73-19.45)] drink alcohol and smoking [4.33; (2.31-8.15)], use illicit substance [4.34; (2.34-8.06)] have mental health problems [3.01; (1.67-5.43)] were more likely to report HAC.

CONCLUSIONS

HAC prevalence is high among university students. The risk of HAC increases with the use of alcohol in family and circle of friends, smoking, illicit substance use and mental health problems. The factors associated with the risk of HAC in both genders are similar.

Short-term changes in social role statuses across young adulthood and their relation to heavy drinking in a given month

Young adulthood is a developmental period during which individuals experience shifts in their social roles in various domains, which coincides with a period of time that is also high risk for lifetime peaks in alcohol use. The current study examined age-related changes in heavy episodic drinking (HED) and high-intensity drinking (HID) and associations with short-term (i.e., monthly) variation in young adults' social roles over a 2.5-year period in a community sample of young adults who reported past-year alcohol use (N = 778, baseline age range 18-23). Results showed probabilities of past-month HED and HID changed in a nonlinear fashion across ages 18-26 with greater probabilities of use at younger ages. Most participants did not report being in the same social role status every sampled month, underscoring the presence of short-term role variation. Living with parents and being in a serious romantic relationship in a given month were negatively associated with past-month HED. Living with parents in a given month was also negatively associated with past-month HID. Being a 4-year college student and being employed full-time in a given month were not significantly related to either outcome. Findings provided partial evidence that monthly statuses were associated with heavy drinking. Several avenues for future research are described in light of the findings.

Effects of experimental, network-based social circle norm feedback on studying behavior and alcohol consumption

Misrepresentation of peer behavior has often been observed in college students and may lead to over-expression of alcohol consumption and under-expression of studying. While social norm feedback approaches have had mixed success in addressing these misrepresentations and altering behavior, they may have been too unspecific to be effective and did not directly assess individual perception accuracy. We thus investigated how specific, one-time feedback on the behavioral distribution of alcohol consumption or study time of a clearly defined, individually-adjusted social circle would affect the respective norm estimations and behavior of a class of Psychology students (n = 89 in January) across their first year of study. Students overestimated alcohol consumption and partially underestimated studying norms. While social circle feedback on alcohol consumption did not clearly affect both individual estimation accuracy and alcohol consumption, feedback on peers' studying time increased studying with no clear effect on estimation accuracy. This indicates that social circle norm feedback may be suitable to evoke behavioral effects. The correction of the detected inaccuracies did not appear to be a precondition for the feedback to be effective.

"I'll Be That One Cockblocking Friend": Understanding Student Experiences of Bystander Intervention in Alcohol-Related Sexual Assault

The prevalence of sexual assault (SA) among college students (13%) is unacceptable, underreported, and alcohol use by the perpetrator or victim is reported in 50% of SA cases. Bystander intervention (BI) programs, which use prosocial behaviors to prevent or stop a harmful situation from occurring, have been implemented across college campuses to reduce SA. There are several known barriers (e.g. self-intoxication) and facilitators (e.g. peer support) to BI for SA; however, less is known about barriers and facilitators to BI for alcohol-related SA. Alcohol-related SA includes situations in which the perpetrator and/or victim are intoxicated, whereas alcohol-facilitated SA includes situations in which individuals intentionally use alcohol as a perpetration strategy. The current study examined student perspectives of BI for SA opportunities, actions taken in response to opportunities, and barriers and facilitators to action. The team conducted content and deductive thematic analysis of data from focus groups and interviews with diverse undergraduate students (N = 79). Opportunities included perpetrator-focused, victim-focused, and sexual risk opportunities. Actions taken included staying vigilant, monitoring friends, communicating with friends, and removing friends. Barriers included self-intoxication, feeling helpless, peer pressure, not feeling personally responsible, and fearing the consequences of helping. Finally, facilitators included knowing friends' concerning signals and drinking motives, feeling like some intervention strategies are easy, understanding sex-related risks, acknowledging consent and personal boundaries, and feeling personally responsible for friends. Understanding these situations' nuances can help to inform more effective and comprehensive BI programs to reduce SA.

Alcohol Feedback, Reflection, and Morning Evaluation (A-FRAME): Refining and testing feasibility and acceptability of a smartphone-delivered alcohol intervention for heavy-drinking young adults

BACKGROUND

Young adults drink heavily and experience negative alcohol consequences. To capitalize on mornings after drinking as an optimal time to intervene, we developed a novel, theory-based personalized feedback intervention (PFI) called Alcohol Feedback, Reflection, and Morning Evaluation (A-FRAME), to reduce heavy drinking. An initial prototype was refined via feedback from college students who drink heavily. The goal of the present study was to conduct an open trial to establish feasibility and acceptability of the refined PFI.

METHODS

The refined PFI was delivered for 4 weeks to 18 heavy-drinking young adults (Mage = 22.61, 44% women, 66.7% White, 27.8% Black, 16.7% Asian, 5.6% Native American/Alaskan Indian, 22.2% Hispanic/Latino). Participants completed a goal-setting procedure, followed by 28 daily surveys. Surveys indicating prior-day drinking were followed by the option to view personalized feedback (e.g., goal attainment, blood alcohol concentration [BAC], peer norms, protective behaviors). Aggregated feedback was also delivered at the 14- and 28-day marks. Participants completed a post-test acceptability survey and individual interviews to inform further refinement.

RESULTS

The response rate to daily surveys was 93.8% and all participants completed study procedures, demonstrating feasibility. Daily feedback was reviewed about half (45.5%) of the time it was offered (i.e., following drinking days). Biweekly feedback was viewed 50% and 56% of the time at 14- and 28-day marks, respectively. Other benchmarks for acceptability were supported by survey and interview results.

CONCLUSIONS

Open trial results support the feasibility and acceptability of this theory-based intervention for heavy-drinking young adults. A planned randomized controlled trial will evaluate efficacy.

The secondhand effects of alcohol use and the risks of drinking to cope

Objective:The secondhand effects of alcohol use (SEA) are adverse consequences caused by another's drinking. This study explored the relationship among the experience of SEAs, alcohol use, and alcohol related consequences (ARC). In addition, we examined whether coping (i.e., adaptive, maladaptive, substance use coping, maladaptive coping without substance use items) served as a moderator of SEA effects on alcohol outcomes. Method: 1,168 students completed a survey assessing SEA, alcohol outcomes, ARC, and coping strategies. Results: SEA was significantly positively associated with alcohol use (RRheavydrinking = 1.05, SE = 0.005, p < .01; RRAUDIT = 1.04, SE = .005, p < .01) as well as ARC (RR = 1.06, SE = .005, p < .01). Various forms of maladaptive coping moderated the relationship between SEA and alcohol outcomes. Conclusion: This study provided evidence for a relationship between SEA and more alcohol use and ARC. This relationship was exacerbated by maladaptive coping.

The Role of Personalized Normative Feedback in the Efficacy of Brief Intervention Among Argentinian University Students: A Randomized Controlled Trial

Background: Personalized Normative Feedback (PNF) aims to modify misperceptions about peer consumption that influence one's drinking. PNF is usually a component in Brief Interventions delivered to university students. Despite this, whether PNF contributes to improving the effect of brief interventions is unclear. Objectives: This randomized controlled trial aimed to determine the role of PNF as an active ingredient in a face-to-face motivational brief intervention. Results: Participants were students from an Argentinian university (n=806; M=20.14; SD=3.17; 63.2% women) who presented at least one binge drinking episode in the last 12 months. Students were randomly assigned to 1) a Brief Intervention, 2) a Brief Intervention with PNF, or 3) an evaluation-only control group. The follow-up was three months later. After controlling sex and age, General Linear Models showed that both the brief intervention and the brief intervention with PNF reduced the quantity and frequency of alcohol consumption, binge drinking, and alcohol problems compared to the control condition. No differences were found between the brief intervention and the brief intervention with PNF. Also, treating eight students with brief intervention and 10 with brief intervention with PNF was necessary to benefit one student. Conclusions: In conclusion, this study demonstrates that brief intervention reduces alcohol consumption among Latin American university students and that PNF might not be an active ingredient of its effectiveness in this population. However, PNF could benefit students with specific characteristics, like those who overestimate their peers' drinking, highlighting the need to study moderators of effectiveness further.

A Deviance Regulation Theory Intervention Affects the Association Between Narcissistic Traits and Alcohol Harm Reduction Strategies in College Students

Background: College students continue to report problematic alcohol use. To mitigate adverse outcomes, recent studies have employed harm reduction strategies known as Protective Behavioral Strategies (PBS). Deviance Regulation Theory (DRT), an impression management intervention, has been used to promote the use of PBS. DRT relies on impression management to modify behavior. This may be especially important for individuals with higher levels of trait narcissism. Method: College student drinkers (n = 132) were randomly assigned to receive a positive message about PBS users, a negative message about non-PBS users, or control. Participants reported on current PBS use norms, daily alcohol use, PBS use, and any alcohol-related problems experienced during the previous week for the next 10 weeks. Results: Data were analyzed using multilevel regression to examine PBS use across time by condition. When PBS norms were low, narcissism was strongly associated with lower rates of PBS use in the control group. If individuals received a positive or negative message, the association between narcissism and PBS use was diminished, among individuals with low PBS norms. There were no significant differences at mean or high levels of norms, indicating the messaging was only important for the highest risk group (i.e., those with low PBS norms). Discussion: The results of this study suggest that message framing may be effective at reducing the robust negative association between narcissism and PBS use for individuals with low PBS norms. Positive messages about individuals that use PBS may be one approach to mitigating problematic alcohol consumption in this at-risk group.

Transdermal alcohol concentration features predict alcohol-induced blackouts in college students

BACKGROUND

Alcohol-induced blackouts (AIBs) are common in college students. Individuals with AIBs also experience acute and chronic alcohol-related consequences. Research suggests that how students drink is an important predictor of AIBs. We used transdermal alcohol concentration (TAC) sensors to measure biomarkers of increasing alcohol intoxication (rise rate, peak, and rise duration) in a sample of college students. We hypothesized that the TAC biomarkers would be positively associated with AIBs.

METHODS

Students were eligible to participate if they were aged 18-22 years, in their second or third year of college, reported drinking 4+ drinks on a typical Friday or Saturday, experienced ≥1 AIB in the past semester, owned an iPhone, and were willing to wear a sensor for 3 days each weekend. Students (N = 79, 55.7% female, 86.1% White, Mage = 20.1) wore TAC sensors and completed daily diaries over four consecutive weekends (89.9% completion rate). AIBs were assessed using the Alcohol-Induced Blackout Measure-2. Logistic multilevel models were conducted to test for main effects.

RESULTS

Days with faster TAC rise rates (OR = 2.69, 95% CI: 1.56, 5.90), higher peak TACs (OR = 2.93, 95% CI: 1.64, 7.11), and longer rise TAC durations (OR = 4.16, 95% CI: 2.08, 10.62) were associated with greater odds of experiencing an AIB.

CONCLUSIONS

In a sample of "risky" drinking college students, three TAC drinking features identified as being related to rising intoxication independently predicted the risk for daily AIBs. Our findings suggest that considering how an individual drinks (assessed using TAC biomarkers), rather than quantity alone, is important for assessing risk and has implications for efforts to reduce risk. Not only is speed of intoxication important for predicting AIBs, but the height of the peak intoxication and the time spent reaching the peak are important predictors, each with different implications for prevention.

Longitudinal examination of alcohol use motives, item-level protective behavioral strategies, and alcohol-related consequences

BACKGROUND

Alcohol misuse among college students is a public health concern. Protective behavioral strategies (PBS) can be used before, during, after, or instead of drinking to reduce alcohol use and negative consequences, but findings on their utility at the aggregate level are mixed. Although recent work has provided important information on the performance of individual PBS items, it is limited by research designs that are cross-sectional, do not examine consequences, or do not examine other important correlates, such as drinking motives. This study examines both the association between item-level PBS and alcohol-related negative consequences and the moderating effect of drinking motives longitudinally.

METHODS

College students from two universities (n = 200, 62.5% female, Mage = 20.16) completed the Drinking Motives Questionnaire-Revised, Protective Behavioral Strategies Survey, the Rutgers Alcohol Problem Index, and a measure of the quantity of alcohol use at baseline and 3-month follow-up. Generalized linear models were conducted to assess direct effects of item-level PBS on alcohol-related consequences and the moderating effects of drinking motives.

RESULTS

Two PBS items were associated with fewer alcohol-related consequences at follow-up, and two items were associated with greater alcohol-related consequences at follow-up. Drinking motives differentially moderated associations between item-level PBS and alcohol-related consequences for a proportion in the sample. Enhancement motives moderated the greatest number of associations, followed by coping, conformity, and social motives. Certain PBS (e.g., drink slowly, rather than gulp or chug) were moderated by several drinking motives, whereas other PBS items were not moderated by any motives.

CONCLUSION

Consistent with previous research, some item-level PBS were associated longitudinally with increased negative consequences, and some were associated with decreased negative consequences. Drinking motives, particularly enhancement, moderated several item-level PBS and consequence associations, suggesting that reasons for drinking may be important for understanding the associations between PBS strategies and alcohol-related consequences.

Developing a Text Messaging Intervention to Prevent Binge and Heavy Drinking in a Military Population: Mixed Methods Development Study

BACKGROUND

Alcohol misuse is the fourth leading cause of death in the United States and a significant problem in the US military. Brief alcohol interventions can reduce negative alcohol outcomes in civilian and military populations, but additional scalable interventions are needed to reduce binge and heavy drinking. SMS text messaging interventions could address this need, but to date, no programs exist for military populations.

OBJECTIVE

We aimed to develop an SMS text messaging intervention to address binge and heavy drinking among Airmen in Technical Training in the US Air Force.

METHODS

We implemented a 2-phase, mixed methods study to develop the SMS text messaging intervention. In phase 1, a total of 149 respondents provided feedback about the persuasiveness of 49 expert-developed messages, preferences regarding message frequency, timing and days to receive messages, and suggested messages, which were qualitatively coded. In phase 2, a total of 283 respondents provided feedback about the persuasiveness of 77 new messages, including those developed through the refinement of messages from phase 1, which were coded and assessed based on the Behavior Change Technique Taxonomy (BCTT). For both phases, mean persuasiveness scores (range 1-5) were calculated and compared according to age (aged <21 or ≥21 years) and gender. Top-ranking messages from phase 2 were considered for inclusion in the final message library.

RESULTS

In phase 1, top-rated message themes were about warnings about adverse outcomes (eg, impaired judgment and financial costs), recommendations to reduce drinking, and invoking values and goals. Through qualitative coding of suggested messages, we identified themes related to warnings about adverse outcomes, recommendations, prioritizing long-term goals, team and belonging, and invoking values and goals. Respondents preferred to receive 1 to 3 messages per week (124/137, 90.5%) and to be sent messages on Friday, Saturday, and Sunday (65/142, 45.8%). In phase 2, mean scores for messages in the final message library ranged from 3.31 (SD 1.29) to 4.21 (SD 0.90). Of the top 5 highest-rated messages, 4 were categorized into 2 behavior change techniques (BCTs): valued self-identity and information about health consequences. The final message library includes 28 BCTT-informed messages across 13 BCTs, with messages having similar scores across genders. More than one-fourth (8/28, 29%) of the final messages were informed by the suggested messages from phase 1. As Airmen aged <21 years face harsher disciplinary action for alcohol consumption, the program is tailored based on the US legal drinking age.

CONCLUSIONS

This study involved members from the target population throughout 2 formative stages of intervention development to design a BCTT-informed SMS text messaging intervention to reduce binge and heavy drinking, which is now being tested in an efficacy trial. The results will determine the impact of the intervention on binge drinking and alcohol consumption in the US Air Force.

Associations between Gender Expression, Protective Coping Strategies, Alcohol Saliency, and High-Risk Alcohol Use in Post-Secondary Students at Two Canadian Universities

BACKGROUND

This study, conducted in October 2017 at two Canadian universities, aimed to explore the relationships between gender expression, protective coping strategies, alcohol saliency, and high-risk alcohol use.

METHODS

Validated scales were employed to assess these variables using survey data. Multivariate analyses were conducted to investigate the associations between these factors and high-risk drinking.

RESULTS

This study revealed significant associations between high-risk drinking and androgynous gender roles (OR = 1.58, 95% CI: 1.19-2.10) as well as among self-reported males (OR = 2.21; 95% CI: 1.77-2.75). Additionally, protective behavioural strategies were inversely related to high-risk drinking (OR = 0.95; 95% CI: 0.94-0.96), while higher alcohol saliency exhibited a positive correlation with high-risk drinking (OR = 1.12; 95% CI: 1.11-1.14).

CONCLUSIONS

These findings underscore the importance of considering gender, alcohol saliency beliefs, and protective behavioural strategies in the development and refinement of interventions aimed at reducing high-risk alcohol use on Canadian campuses.

Exposure to media with alcohol-related content across young adulthood: Associations with risky drinking and consequences among high-risk 2- and 4-year college students

INTRODUCTION

Exposure to media with alcohol-related content is a known risk for alcohol use and related harms among young people. The present study used longitudinal self-report data on exposure to media with alcohol-related content to examine age trajectories across young adulthood and to estimate associations with heavy episodic drinking (HED) and negative consequences.

METHOD

Participants were 201 high-risk young adults enrolled in 2- and 4-year colleges (ages 18-25 at screening; 63.7% female). Repeated assessments occurred at four timepoints across a 12-month period.

RESULTS

Self-reported exposure to both positively and negatively portrayed alcohol-related media content decreased with age. Between-persons, controlling for alcohol use frequency, exposure to positive alcohol-related media content was positively associated with HED, and exposure to negative alcohol-related media content was inversely associated with HED; no within-person effects on HED were significant. For negative consequences, controlling for alcohol quantity, exposure to positive media content was associated with more negative consequences both between- and within-persons. Unexpectedly, exposure to negatively portrayed media content was positively associated with negative consequences at the within-person level.

DISCUSSION AND CONCLUSIONS

Trajectories in exposure to media with alcohol-related content showed that relatively younger participants reported greater exposure, highlighting the need for policy and prevention efforts to protect this vulnerable demographic. Findings generally indicated that positive portrayals of alcohol use increase alcohol-related risks. Moreover, increased exposure to negative portrayals in a given assessment was associated with more negative consequences-potentially by normalising or glorifying high-risk drinking and consequences, though mechanistic/causal research is needed.

Motivational interviewing for substance use reduction

BACKGROUND

Substance use is a global issue, with around 30 to 35 million individuals estimated to have a substance-use disorder. Motivational interviewing (MI) is a client-centred method that aims to strengthen a person's motivation and commitment to a specific goal by exploring their reasons for change and resolving ambivalence, in an atmosphere of acceptance and compassion. This review updates the 2011 version by Smedslund and colleagues.

OBJECTIVES

To assess the effectiveness of motivational interviewing for substance use on the extent of substance use, readiness to change, and retention in treatment.

SEARCH METHODS

We searched 18 electronic databases, six websites, four mailing lists, and the reference lists of included studies and reviews. The last search dates were in February 2021 and November 2022.

SELECTION CRITERIA

We included randomised controlled trials with individuals using drugs, alcohol, or both. Interventions were MI or motivational enhancement therapy (MET), delivered individually and face to face. Eligible control interventions were no intervention, treatment as usual, assessment and feedback, or other active intervention.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane, and assessed the certainty of evidence with GRADE. We conducted meta-analyses for the three outcomes (extent of substance use, readiness to change, retention in treatment) at four time points (post-intervention, short-, medium-, and long-term follow-up).

MAIN RESULTS

We included 93 studies with 22,776 participants. MI was delivered in one to nine sessions. Session durations varied, from as little as 10 minutes to as long as 148 minutes per session, across included studies. Study settings included inpatient and outpatient clinics, universities, army recruitment centres, veterans' health centres, and prisons. We judged 69 studies to be at high risk of bias in at least one domain and 24 studies to be at low or unclear risk. Comparing MI to no intervention revealed a small to moderate effect of MI in substance use post-intervention (standardised mean difference (SMD) 0.48, 95% confidence interval (CI) 0.07 to 0.89; I2 = 75%; 6 studies, 471 participants; low-certainty evidence). The effect was weaker at short-term follow-up (SMD 0.20, 95% CI 0.12 to 0.28; 19 studies, 3351 participants; very low-certainty evidence). This comparison revealed a difference in favour of MI at medium-term follow-up (SMD 0.12, 95% CI 0.05 to 0.20; 16 studies, 3137 participants; low-certainty evidence) and no difference at long-term follow-up (SMD 0.12, 95% CI -0.00 to 0.25; 9 studies, 1525 participants; very low-certainty evidence). There was no difference in readiness to change (SMD 0.05, 95% CI -0.11 to 0.22; 5 studies, 1495 participants; very low-certainty evidence). Retention in treatment was slightly higher with MI (SMD 0.26, 95% CI -0.00 to 0.52; 2 studies, 427 participants; very low-certainty evidence). Comparing MI to treatment as usual revealed a very small negative effect in substance use post-intervention (SMD -0.14, 95% CI -0.27 to -0.02; 5 studies, 976 participants; very low-certainty evidence). There was no difference at short-term follow-up (SMD 0.07, 95% CI -0.03 to 0.17; 14 studies, 3066 participants), a very small benefit of MI at medium-term follow-up (SMD 0.12, 95% CI 0.02 to 0.22; 9 studies, 1624 participants), and no difference at long-term follow-up (SMD 0.06, 95% CI -0.05 to 0.17; 8 studies, 1449 participants), all with low-certainty evidence. There was no difference in readiness to change (SMD 0.06, 95% CI -0.27 to 0.39; 2 studies, 150 participants) and retention in treatment (SMD -0.09, 95% CI -0.34 to 0.16; 5 studies, 1295 participants), both with very low-certainty evidence. Comparing MI to assessment and feedback revealed no difference in substance use at short-term follow-up (SMD 0.09, 95% CI -0.05 to 0.23; 7 studies, 854 participants; low-certainty evidence). A small benefit for MI was shown at medium-term (SMD 0.24, 95% CI 0.08 to 0.40; 6 studies, 688 participants) and long-term follow-up (SMD 0.24, 95% CI 0.07 to 0.41; 3 studies, 448 participants), both with moderate-certainty evidence. None of the studies in this comparison measured substance use at the post-intervention time point, readiness to change, and retention in treatment. Comparing MI to another active intervention revealed no difference in substance use at any follow-up time point, all with low-certainty evidence: post-intervention (SMD 0.07, 95% CI -0.15 to 0.29; 3 studies, 338 participants); short-term (SMD 0.05, 95% CI -0.03 to 0.13; 18 studies, 2795 participants); medium-term (SMD 0.08, 95% CI -0.01 to 0.17; 15 studies, 2352 participants); and long-term follow-up (SMD 0.03, 95% CI -0.07 to 0.13; 10 studies, 1908 participants). There was no difference in readiness to change (SMD 0.15, 95% CI -0.00 to 0.30; 5 studies, 988 participants; low-certainty evidence) and retention in treatment (SMD -0.04, 95% CI -0.23 to 0.14; 12 studies, 1945 participants; moderate-certainty evidence). We downgraded the certainty of evidence due to inconsistency, study limitations, publication bias, and imprecision.

AUTHORS' CONCLUSIONS

Motivational interviewing may reduce substance use compared with no intervention up to a short follow-up period. MI probably reduces substance use slightly compared with assessment and feedback over medium- and long-term periods. MI may make little to no difference to substance use compared to treatment as usual and another active intervention. It is unclear if MI has an effect on readiness to change and retention in treatment. The studies included in this review were heterogeneous in many respects, including the characteristics of participants, substance(s) used, and interventions. Given the widespread use of MI and the many studies examining MI, it is very important that counsellors adhere to and report quality conditions so that only studies in which the intervention implemented was actually MI are included in evidence syntheses and systematic reviews. Overall, we have moderate to no confidence in the evidence, which forces us to be careful about our conclusions. Consequently, future studies are likely to change the findings and conclusions of this review.

Whose Approval Matters Most? Examining Discrepancies in Self- and Other- Perceptions of Drinking

BACKGROUND

Research demonstrates that perceptions of others' attitudes toward drinking behaviors (injunctive norms) are strong predictors of alcohol consumption and problems. Personalized normative feedback (PNF) aims to reduce the discrepancy between one's perception of others' attitudes toward drinking and others' actual attitudes toward drinking. An implicit assumption of PNF is that self and (perceived) other attitudes toward drinking are aligned (thus, shifting one's perceptions of others' attitudes shifts one's own attitudes). However, there is minimal research on the extent to which alignment (or discrepancy) in self-other attitudes toward drinking is associated with alcohol-related outcomes.

METHODS

College students (N = 1,494; Mage = 20.11, 61.0% female, 66.4% White) who endorsed past-month heavy episodic drinking reported injunctive norms toward drinking on weekends, drinking daily, drinking to black out, and drinking and driving. Participants reported their perceptions of attitudes toward these drinking behaviors for three reference groups: close friends, typical university-affiliated peers, and parents. Outcomes included weekly drinking, alcohol problems, and alcohol-related risk.

RESULTS

Response surface analyses indicated that alignment in approval (versus alignment in disapproval) of drinking demonstrated a linear association with alcohol-related outcomes. Discrepancies in self-peer and self-parent attitudes were associated with alcohol-related outcomes and one's own attitudes (versus one's ratings of others' attitudes) of drinking were more strongly associated with outcomes.

CONCLUSIONS

Results provide evidence of how self-other discrepancies in attitudes toward drinking are associated with alcohol-related outcomes. Future work is needed to test whether self-other discrepancies in attitudes toward drinking impacts response to norms-based interventions.

Preliminary Effects of a Guided Self-Change Intervention on Perceived Risk and Self-Efficacy in University Students Engaging in Cannabis or Alcohol Misuse

Guided Self-Change (GSC) is a Motivational Interviewing (MI)-based early intervention program, infused with Cognitive Behavioral Therapy (CBT), for individuals with substance use problems. In this study, we implemented a 4-session GSC program with the innovative addition of mindfulness-based techniques at a minority-serving institution to reduce substance use and negative consequences among self-referred university students. We investigated processes that may be associated with behavior change, including perceived risk of use and self-efficacy ratings among university students who reported their primary substance of choice was cannabis (n = 18) or alcohol (n = 18). The sample of 36 participants (Mage = 24.4, SDage = 5, range 18-37) mostly identified as female (58.3%), then male (41.7%); 52.8% identified as Hispanic/Latine, 22.2% as Black or African American, and 19.5% as a sexual minority. Among cannabis primary using students, results indicated that the perceived risk of weekly cannabis use, confidence to change, and readiness to change showed statistically significant increases from pre- to post-assessment. Among alcohol primary using students, confidence to change and readiness to change showed statistically significant increases from pre- to post-assessments. All results yielded large effect sizes, which may be inflated due to the small sample size. Findings suggest that over the course of participation in a brief, 4-session targeted GSC program, there were significant increases in perceived risk and self-efficacy among minority university students who engage in primary cannabis or primary alcohol use.

Daily-level associations between alcohol use cognitions and normative perceptions among adolescents: An intensive longitudinal study

BACKGROUND

Adolescence is an important developmental period in which to understand the cognitive underpinnings of risky alcohol use. Normative perceptions, such as descriptive and injunctive norms, are one of the strongest and most consistent predictors in adolescent drinking research. Thus, it is essential to examine which drinking cognitions (e.g., attitudes, prototypes, perceived vulnerability) are associated with normative drinking perceptions using repeated daily-level data among adolescents. The present study assessed associations between drinking cognitions and normative perceptions using an intensive daily longitudinal design.

METHODS

Participants were ages 15-17 years (N = 306; 61.4% female; Mage (SD) = 16.0 (0.8)) who were part of a larger ecological momentary assessment study (EMA) on drinking cognitions and alcohol use. The study design consisted of a 3-week EMA burst design (8 surveys per week, up to 2x/day) that was repeated quarterly over the 12-month study. The present analyses used the afternoon assessment for all measures.

RESULTS

Our multilevel model results demonstrated that drinking attitudes, prototypes of a typical drinker, and perceived vulnerability were positively associated with both descriptive and injunctive drinking norms between individuals and within individuals across days.

CONCLUSIONS

Current findings have important clinical implications as they demonstrated how specific drinking cognitions were associated with variability in normative perceptions at the daily level. Findings support the delivery of intervention messaging to adolescents on days when drinking attitudes, prototypes of a typical drinker, and perceived vulnerability are elevated.

Feasibility and Acceptability of the Social Media-Brief Alcohol Screening and Intervention for College Students Intervention

PURPOSE

Community college (CC) students represent an at-risk population for alcohol use with limited access to campus interventions. The Brief Alcohol Screening and Intervention for College Students (BASICS) is available online, though identifying CC students at risk and connecting them to interventions remains challenging. This study tested a novel approach using social media to identify at-risk students and prompt delivery of BASICS.

METHODS

This randomized controlled trial examined the feasibility and acceptability of Social Media-BASICS. Participants were recruited from five CCs. Baseline procedures included a survey and social media friending. Social media profiles were evaluated using content analysis monthly for nine months. Intervention prompts included displayed alcohol references indicating escalation of or problematic alcohol use. Participants who displayed such content were randomized into the BASICS intervention or an active control. Measures and analyses assessed feasibility and acceptability.

RESULTS

A total of 172 CC students completed the baseline survey, mean age was 22.9 (standard deviation = 3.18) years. Most were female (81%), with many (67%) identifying as White. Among participants, 120 (70%) displayed alcohol references on social media, prompting intervention enrollment. Of randomized participants, 94 (93%) completed the preintervention survey within 28 days of the invitation. The majority of participants reported positive intervention acceptability.

DISCUSSION

This intervention combined two validated approaches: identification of problem alcohol use displays on social media, and provision of the Web-BASICS intervention. Findings demonstrate the feasibility for novel web-based interventions to reach CC populations.

Relations between peer influence, perceived costs versus benefits, and sexual offending among adolescents aware of sex offender registration risk

A policy's general deterrent effect requires would-be offenders to be aware of the policy, yet many adolescents do not know they could be registered as sex offenders, and even adolescents who do know may still commit registerable sexual offenses. We tested whether peer influences shape the perceived costs/benefits of certain sexual offenses and, subsequently, registration policy's general deterrent potential in a sample of policy-aware adolescents. The more adolescents believed their peers approve of sexting of nude images, the more likely they were to have sexted. For forcible touching, having more positive peer expectations about sex and perceiving forcible touching as more prevalent among peers related to adolescents' likelihood of engaging in that behavior. Perceiving registration as a possible consequence was unrelated to sexual offending. Findings highlight the nuanced roles peers play in adolescent sexual decision-making and support emerging evidence that juvenile registration policy has limited general deterrent efficacy.

Evaluating effects of IBEM-U on decreasing alcohol consumption and heavy episodic drinking among university students in Colombia: Protocol for a randomized control trial

Background

Alcohol misuse is a serious problem among university students in Colombia as well as in other Latin American countries. Studies show consistently that this population presents the highest rates of alcohol use. Despite such a situation, there is a lack of preventive programs for university students in this region of the world. The purpose of this paper is to present the protocol to evaluate a preventive strategy called IBEM-U, based on Motivational Interviewing and the I-Change Model.

Method

This protocol shows how the evaluation of the effectiveness of the IBEM-U program will be carried out. A randomized control trial with a within-subjects design with one follow-up at six months after the post-test will be implemented. The comparison group will receive an alternative program similar in length but focusing on another issue. Around 1000 participants over 18 years of age, from at least six different universities around the country, will be recruited.

Results

It is expected that the program will be effective in reducing past month alcohol consumption up to 15% in the experimental group as the main outcome. Secondary and tertiary outcomes include decreasing heavy episodic drinking and increasing knowledge, awareness, risk perception, attitude, self-efficacy, intention, and action planning, regarding heavy episodic drinking.

Conclusion

IBEM-U can be considered a highly appropriate approach for reducing alcohol misuse among university students. The main reasons for these results are the self-imposed goals based on long-term purposes, that could be seriously affected by the ingestion of high amounts of alcohol.

Acculturation of hygiene norms among immigrants to Sweden

Hygiene norms in Sweden are generally loose compared to most other countries. Does this looseness affect the hygiene norms among people who immigrate to Sweden from other countries? In a study of hygiene norms among immigrants to Sweden, the change in the physical environment and material living conditions, acculturation to Swedish culture and norms, and selection effects were all expected to lead immigrant hygiene norms to be closer to Swedish looseness. However, in a sample of 447 immigrants from 12 different countries, immigrants reported hygiene norms that were even stricter than those found in their countries of origin. We propose an explanation based on a combination of uncertainty about prevailing hygiene norms and the social risk and stigma associated with being perceived as unhygienic. We conclude that acculturation processes may rely on mechanisms that are domain specific.

Past year high-intensity drinking moderates the association between simultaneous alcohol and marijuana use and blackout frequency among college students

Objective: The role of simultaneous alcohol and marijuana (SAM) use in the experience of blackouts among college students is unclear. To clarify discrepancies, the current study evaluated whether the association between SAM user status and blackouts was moderated by high-intensity drinking (HID). Participants and Methods: College students (N = 1,224; 63.7% female) reported on their past year experiences of blackout, marijuana use, SAM use, and HID (i.e., drinking at least twice the binge threshold). Results: SAM users had more past year blackouts than non-SAM users, but this effect was only significant among SAM users who had engaged in HID in the past year (nonbinge: F(5,37) = 0.50, p = 0.49; binge: F(5,138) = 0.23, p = 0.63; HID: F(5,328) = 4.52, p = 0.03). Conclusions: Effects of SAM user status on the experience of alcohol-related blackouts may be limited to individuals who engage in HID.

Data Quality and Study Compliance Among College Students Across 2 Recruitment Sources: Two Study Investigation

BACKGROUND

Models of satisficing suggest that study participants may not fully process survey items and provide accurate responses when survey burden is higher and when participant motivation is lower. Participants who do not fully process survey instructions can reduce a study's power and hinder generalizability. Common concerns among researchers using self-report measures are data quality and participant compliance. Similarly, attrition can hurt the power and generalizability of a study.

OBJECTIVE

Given that college students comprise most samples in psychological studies, especially examinations of student issues and psychological health, it is critical to understand how college student recruitment sources impact data quality (operationalized as attention check items with directive instructions and correct answers) and retention (operationalized as the completion of follow-up surveys over time). This examination aimed to examine the following: whether data quality varies across recruitment sources, whether study retention varies across recruitment sources, the impact of data quality on study variable associations, the impact of data quality on measures of internal consistency, and whether the demographic qualities of participants significantly vary across those who failed attention checks versus those who did not.

METHODS

This examination was a follow-up analysis of 2 previously published studies to explore data quality and study compliance. Study 1 was a cross-sectional, web-based survey examining college stressors and psychological health (282/407, 69.3% female; 230/407, 56.5% White, 113/407, 27.8% Black; mean age 22.65, SD 6.73 years). Study 2 was a longitudinal college drinking intervention trial with an in-person baseline session and 2 web-based follow-up surveys (378/528, 71.6% female; 213/528, 40.3% White, 277/528, 52.5% Black; mean age 19.85, SD 1.65 years). Attention checks were included in both studies to assess data quality. Participants for both studies were recruited from a psychology participation pool (a pull-in method; for course credit) and the general student body (a push-out method; for monetary payment or raffle entry).

RESULTS

A greater proportion of participants recruited through the psychology pool failed attention checks in both studies, suggesting poorer data quality. The psychology pool was also associated with lower retention rates over time. After screening out those who failed attention checks, some correlations among the study variables were stronger, some were weaker, and some were fairly similar, potentially suggesting bias introduced by including these participants. Differences among the indicators of internal consistency for the study measures were negligible. Finally, attention check failure was not significantly associated with most demographic characteristics but varied across some racial identities. This suggests that filtering out data from participants who failed attention checks may not limit sample diversity.

CONCLUSIONS

Investigators conducting college student research should carefully consider recruitment and include attention checks or other means of detecting poor quality data. Recommendations for researchers are discussed.

The effectiveness of a mobile intervention to reduce young adults' alcohol consumption to not exceed low-risk drinking guidelines

Background

Young adults' drinking habits often exceed low-risk drinking guidelines. As young adults show increased access, use, and interest in personalized content related to physical and mental well-being, mobile applications might be a suitable tool to reach this target group. This study investigates the effectiveness of "Boozebuster", a self-guided mobile application incorporating various therapeutic principles to reduce young adults' alcohol consumption to not exceeding low-risk drinking guideline levels, compared to an educational website condition.

Method

Young adults aged 18-30 wanting to reduce their alcohol consumption entered a two-arm, parallel-group RCT. There were no minimum drinking severity inclusion criteria. Primary outcomes included alcohol consumption quantity and frequency. Secondary outcomes included binge drinking frequency and alcohol-related problem severity. Baseline, 6-week postbaseline, and 3-month post-baseline assessments were analyzed using linear mixed model analyses. Sex, treatment adherence, experienced engagement and motivation to change alcohol use behavior were investigated as moderators. Sub-group analyses contained problem drinkers and binge drinkers.

Results

503 participants were randomized to the intervention or control condition. Results showed no intervention effects on primary or secondary outcomes compared to the control group. Both groups showed within-group reductions on all outcomes. Sub-group analyses in problem drinkers or binge drinkers showed similar results. Motivation to change drinking behavior and experienced engagement with the application significantly moderated the intervention effect regarding the quantity or frequency of alcohol consumption, respectively. Exploratory analyses showed that participants who indicated they wanted to change their drinking patterns during the initial PNF/MI module showed a significantly greater reduction in drinking quantity compared to those who indicated not wanting to change their drinking patterns.

Conclusion

The intervention group did not show a greater reduction in alcohol-related outcomes compared to the control group, but both groups showed a similar decrease. Potential explanations include similar effectiveness of both condition due to using a minimal active control in participants predominantly in the action stage of motivation to change. Future research should further explore the effectiveness of using mobile application to reduce young adults' drinking behavior to not exceed low-risk drinking guideline levels and identify factors that motivate participants to engage with such an intervention.

Strengthening personalized norm feedback interventions: The ambivalent-attitude effect

•

Personalized norm feedback effectively reduces heavy drinking in college students.

•

Inducing ambivalence makes norms a stronger predictor of behavior.

•

We predicted that ambivalence before the PNF would lower alcohol intentions.

•

Ambivalent Ps intended to drink less re compared to those low in ambivalence.

•

Ambivalence should be included in personalized norm feedback interventions.

This study investigated the effect of induced attitude ambivalence on the relationship between the personalized norm feedback (PNF) intervention and heavy drinking by college students. College students consume more alcohol and engage in binge drinking at greater rates than most segments of the population. Given the harmful effects of binge drinking and other risky drinking behaviors, it is important to implement effective interventions to reduce alcohol consumption. PNF is an effective intervention for reducing heavy drinking where students compare their drinking and perceptions of normative drinking with actual drinking norms. Past research suggests that inducing ambivalence makes norms a stronger predictor of behavior. We hypothesized that induced attitudinal ambivalence before the PNF intervention would lower intentions to consume alcohol. This study was a one-way design with ambivalence about drinking (high vs low) as the independent variable and intentions to drink alcohol in the future as the dependent variable (N = 338, 76 % female, M_age = 19.76, SD = 2.61). All participants received the PNF intervention after the ambivalence manipulation and before the intentions to drink alcohol measure. Results from the generalized linear model revealed a significant effect for ambivalence, p =.028. As predicted, participants in the high ambivalence condition intended to drink fewer drinks in one sitting in the future compared to those in the low ambivalence condition. These results suggest that ambivalence may play an important role in make PNF interventions more effective, though more research is necessary to untangle the relationship between ambivalence and norms.

A combined laboratory and field test of a smartphone breath alcohol device and blood alcohol concentration estimator to facilitate moderate drinking among young adults

OBJECTIVE

Innovative strategies are needed to reduce young adult drinking. Real-time feedback via mobile health (mHealth) technology (e.g., smartphone devices/apps) may facilitate moderate drinking, yet requires evidence of feasibility, acceptability, and usability.

METHOD

Young adults reporting frequent heavy drinking (N = 99, Mage = 23, 51% male) participated in a manualized, brief, motivational interview on recent typical and peak blood alcohol concentration (BAC), then were randomized to use 1 of the 3 forms of technology: (a) smartphone breathalyzer device/app; (b) app that estimates BAC based on factors including sex, weight, number/types of drinks over time; or (c) self-text messaging after each drink. Technologies were tested initially in small-group laboratory alcohol self-administration sessions. Participants then completed a 2-week field test wherein they had free access to all three technologies. Participants reported on usability and acceptability.

RESULTS

Laboratory alcohol self-administration did not differ significantly by technology condition. The smartphone breathalyzer and BAC estimator app had favorable acceptability and usability. Participants used at least one form of technology on 67% of drinking days in the field period. In exploratory analyses, alcohol use during the field period was significantly lower than the baseline including a decrease of nearly one drink per drinking day.

CONCLUSIONS

These findings support the feasibility of research combining lab and field methods to test moderate drinking technologies in young adults. Findings further support the acceptability and usability of these technologies, along with young adults' openness to using them. Exploratory results suggest potential efficacy of combined mobile technology intervention to be tested in subsequent controlled studies. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Genetically influenced externalizing and internalizing risk pathways as novel prevention targets

Objective: Risky substance use among college students is widespread, and associated with numerous adverse consequences. Current interventions focus primarily on students' current substance use; we hypothesize that shifting focus from current use to underlying risk factors is a complementary approach that may improve effectiveness of prevention/intervention programming. This approach aligns with the personalized medicine movement, which aims to harness knowledge about underlying etiological factors to provide individuals with specific information about their unique risk profiles and personalized recommendations, to motivate and enable individuals to better self-regulate their health. Method: Our group is building and evaluating an online Personalized Feedback Program (PFP) for college students that provides feedback about the individual's underlying genetically influenced externalizing and internalizing risk factors for substance use, along with personalized recommendations/resources. The project capitalizes on work from a university-wide research project (Spit for Science; S4S), in which > 12,000 students (˜70% of 5 years of incoming freshmen) are being followed longitudinally to assess substance use and related factors across the college years. In this article, we describe our foundational work to develop the PFP. Results: From the S4S data, we have identified risk factors across four domains (Sensation Seeking, Impulsivity, Extraversion, and Neuroticism) that are correlated with college students' substance use. We developed an online self-guided PFP, in collaboration with professionals from student affairs, and using feedback from students, with the ultimate goal of conducting a randomized clinical trial. Conclusion: The provision of personalized risk information represents a novel approach to complement and extend existing college substance use programming.

Efficacy of screening and brief intervention for hazardous alcohol use in patients with mood disorders: A randomized clinical trial from a psychiatric out-patient clinic in India

AIM

To determine the efficacy of individual-based, face-to-face screening and brief intervention (SBI) for hazardous alcohol use among treatment-seeking outpatients with mood disorders.

METHODS

It was a parallel-group, single-blind, randomized controlled trial of 84 participants who met the selection criteria for hazardous alcohol use, defined by alcohol use disorder identification test (AUDIT) score 8-19. Participants were randomly allocated to either SBI or general advice group. Both groups had received a standard care for mood disorders. The outcome was assessed after 3 months. The primary outcome was a change in the mean AUDIT score and the secondary outcomes were a change in frequency of heavy episodic drinking and stages of motivation.

RESULTS

Majority (60%) had major depressive episodes. There was no significant difference in baseline demography and clinical variables between the groups. Both intention to treat and per-protocol analyses showed a small but significant effect of SBI on mean AUDIT score. Age, baseline AUDIT, and motivation did not moderate the effect. SBI was associated with a significant decrease in the frequency of heavy drinking and improvement in stages of motivation.

CONCLUSION

SBI among patients with mood disorders had a small but significant effect on alcohol use.

Explanations for the Cloudy Evidence That Theory Benefits Health Promotion

Persuasive arguments for using theory have been influential in health behavior and health promotion research. The use of theory is expected to improve intervention outcomes and facilitate scientific advancement. However, current empirical evaluations of the benefits of theory have not consistently demonstrated strong effects. A lack of resolution on this matter can be attributed to several features of the current body of evidence. First, the use of theory may be confounded with other features that impact health-related outcomes. Second, measurement of theory use has not been reliable. Third, the field conflates models and theories. Lastly, the evidentiary status and applicability of theories are not considered. Addressing these challenges during the execution of meta-analyses and designing original research specifically to estimate the benefits of theory could improve research and practice.

Expectancies and Motives as Predictors of Risky Alcohol Consumption in College Women

Despite the consequences of alcohol use, it continues showing a high incidence among college students. Besides, the increasing presence of women in risk alcohol patterns calls for a gender-sensitive approach to design specific actions. Some variables have been analyzed as underlying alcohol consumption (expectations and motives). This paper assesses the type and influence of both variables on female university alcohol consumers at different levels of risk. Five hundred four college women were assessed using the Spanish adaptations of the Expectancy Questionnaire, the Drinking Motives Questionnaire-Revised, and the AUDIT. We determine the unique contributions of expectancies, motives, and the presence of binge drinking (BD) to the pattern of risky drinking. The percentage of variance explained by risky drinking is 37.7%. Negative expectancies (20.4%) are the most explanatory variables, followed by enhancement motives (10.4%). Interventions with university women should focus on their negative expectancies, in addition to addressing for improvement, coping with depression, and conformity motives.

Cultural adaptation of the mental health first aid guidelines for Brazilians with problem drinking: a Delphi expert consensus study

BACKGROUND

Harmful use of alcohol is highly prevalent around the world and results in a large disease burden. Most people who meet the criteria for an alcohol use disorder do not receive treatment. Those in a person's social network can be useful in recognizing a problem and encouraging the person to seek treatment. However, many people lack the knowledge and skills to do this effectively. This study reports on the cultural adaptation for Brazil of the 2009 English-language mental health first aid guidelines for helping someone with problem drinking.

METHODS

A Delphi expert consensus study with two expert panels, one comprising health professionals with experience in the treatment of problem drinking and the other comprising people with lived experience was conducted. Participants rated the importance of actions to be taken to help a person with problem drinking.

RESULTS

Over two rounds, 60 participants (30 professionals and 30 people with lived experience) rated 197 items. A total of 166 items were included in the final guidelines.

CONCLUSIONS

While there were many similarities with the English-language guidelines for high-income countries, the guidelines also incorporate actions of importance for Brazil, including compulsory treatment and different approaches to dealing with people with problem drinking. Further research is necessary to assess their impact.

Personal and Social Consequences of Psychotropic Substance Use: A Population-Based Internet Survey

Background and objectives: Drug abuse has become a major worldwide health concern among all age groups. The present study analyses substance misuse and its social and personal consequences using a population-based internet survey in Spain. Materials and Methods: Screening for drug abuse (of alcohol, marijuana/hashish and psychostimulants) and its related risks and problems was performed using the Car, Relax, Alone, Forget, Friends, Trouble (CRAFFT) score. Socio-demographic factors, depressive, anxiety and stress symptoms as well as health habits were also evaluated. We used Linear regression methods to compare each variable's individual contribution so as to determine which one best explains the results. Results: In this population-based study, 1224 people completed and returned the online survey. Of all participants, 57% reported consuming at least one substance based on the CRAFFT scale. While increasing age reduces the probability of personal and social consequences of consumption, people who smoke receive up to three times more (OR = 3.370) recommendations from family and friends to reduce their consumption. As for the type of substance, the consumption of marijuana increases the risk of forgetting (OR = 2.33) and the consumption of other psychostimulant substances almost triples the risk of consuming alone (OR = 2.965). Combining substances can increase the rate of driving a vehicle after consumption by 3.4 times. Conclusions: Although age, smoking and the type of substances used increase the risk of suffering from social and personal consequences of the use or abuse of substances, future studies are needed to determine the influence of new variables as a potential tool for treating and minimizing the adverse consequences of drug abuse.

Prevention of Alcohol-related Incidents in the U.S. Air Force: Results From a Cluster Randomized Trial

BACKGROUND

Alcohol misuse poses significant public health concerns in the U.S. Military. An Alcohol Misconduct Prevention Program (AMPP), which includes a brief alcohol intervention (BAI) session, plus random breathalyzer program, has been shown to reduce alcohol-related incidents (ARIs) among Airmen undergoing training.

PURPOSE

The current study sought to examine whether a booster BAI administered at the end of Airmen's training reduced ARIs out to a 1-year follow-up.

METHODS

Participants were 26,231 U.S. Air Force Technical Trainees recruited between March 2016 and July 2018. Participants were cluster randomized by cohort to two conditions: AMPP + BAI Booster or AMPP + Bystander Intervention. The primary analysis was a comparison of the interventions' efficacies in preventing Article 15 ARIs at a 1-year follow-up, conducted using a generalized estimating equations logistic regression model controlling for covariates.

RESULTS

There was no significant difference by condition in Article 15 ARIs at the 1-year follow-up (P = .912).

CONCLUSIONS

Findings suggest that a booster may not be necessary to produce maximum effects beyond the initial AMPP intervention. It is also possible that alcohol behaviors changed as a result of the intervention but were not captured by our outcome measures. Future research should consider alternative outcomes or participant-tracking measures to determine whether a different or more intensive BAI booster is effective. The majority of Article 15 ARIs were for underage drinking; therefore, developing an intervention focused on this problem behavior could lead to large reductions in training costs in the military.

Associations between alcohol demand and both the experience and subjective evaluation of positive and negative alcohol-related consequences

BACKGROUND

Considerable variation exists in the extent to which alcohol-related consequences are evaluated as positive or negative. These evaluations, in turn, predict subsequent drinking behavior. Understanding the etiological pathways to positive and negative alcohol-related consequences is essential to the design of interventions aimed at reducing drinking consequences. Behavioral economic models posit that excessive alcohol valuation contributes to problematic use. Elevated alcohol demand (i.e., relative alcohol value) is associated with negative alcohol-related consequences; however, it is unclear whether demand is related to positive consequences or subjective consequence evaluations.

METHODS

College student drinkers (n = 114; 74.6% female) completed an online survey. Participants indicated whether they had ever experienced any of 24 negative and 14 positive consequences and subjectively evaluated their most recent experience of each consequence endorsed. An alcohol purchase task assessed hypothetical alcohol consumption across 14 prices and three observed demand indices were calculated: intensity (i.e., consumption at zero cost), O_max (i.e., maximum expenditure), and P_max (i.e., price associated with maximum expenditure). Bivariate correlations and hierarchical regressions were used to test associations between observed demand indices and the number and subjective evaluations of positive and negative (researcher- and participant-defined) consequences.

RESULTS

Intensity and O_max , but not P_max , were bivariately associated with researcher- and participant-defined negative and positive consequences. However, in hierarchical regression models that controlled for the maximum number of drinks consumed in a single day over the past month, only intensity was significantly associated with more negative and positive consequences. Intensity was associated with positive consequence evaluations in bivariate but not regression models.

CONCLUSION

Students with higher intensity reported more prior alcohol consequences (positive and negative), independent of drinking level. However, subjective evaluations of recent consequences did not vary as a function of demand. Results support using behavioral economic models to facilitate identifying etiologic pathways to alcohol consequences and suggest that novel interventions incorporating demand manipulation may reduce drinking consequences.

Predictors of health behaviors during a college national championship sports event: A daily diary study

Objective: Few studies have examined relations between college sporting events and maladaptive health behaviors among non-athlete college students. Participants: 97 college students. Methods: Completed nightly surveys (alcohol, eating, physical activity, sexual risk taking, smoking) for 11 days around a National Championship game. Results: Baseline stress and rumination was related to worse health behavior; mindfulness was related to better health behavior. Hierarchical linear modeling showed that all maladaptive health behaviors significantly increased the day of the sporting event compared to individuals' baseline levels. Rumination significantly predicted a spike in alcohol use and sexual risk taking behavior on the day of the Championship game. Conclusions: Risk factors for maladaptive health behaviors include stress and rumination, while mindfulness is protective. Interventions may work to make sports events on campus safer for students (e.g., condoms, reminder emails, mindfulness interventions for at risk groups); more research is needed.

Brief Alcohol Screening and Intervention for Community College Students (BASICCS): Feasibility and preliminary efficacy of web-conferencing BASICCS and supporting automated text messages

Objective: The Brief Alcohol Screening and Intervention for College Students (BASICS; Dimeff et al., 1999) is an evidence-based approach to reduce high-risk drinking and associated harms; however, implementation may present challenges for community colleges (CCs) that have limited budgets and mostly non-residential students. We examined feasibility, acceptability, and efficacy of BASICS for CC students (BASICCS) delivered remotely via web-conferencing with supporting automated text messages. Method: Participants included 142 CC students who reported exceeding National Institute on Alcohol Abuse and Alcoholism (NIAAA's) weekly low-risk drinking recommendations and/or heavy episodic drinking (HED). Participants were randomized to BASICCS or assessment-only control (AOC) and completed 1- and 3-month follow-up assessments. Results: Most students liked the personalized information in the program and found the web-conferencing platform useful, however intervention completion rate was 56%. Significant differences were found between BASICCS and AOC. At 1-month, individuals in BASICCS had 33% fewer alcohol consequences than those in AOC. At 3-month follow-up, individuals in BASICCS had lower estimated peak blood alcohol concentration, 29% fewer drinks per week, 62% fewer episodes of HED, and 24% fewer consequences than those in AOC. Conclusions: BASICCS showed evidence of being acceptable and the technology proved feasible, although the intervention completion rate in the non-treatment-seeking volunteer sample was modest. Preliminary evidence does suggest BASICCS shows promise in reducing alcohol use and consequences. Technology-based platforms could be a viable prevention solution for CC students.

Psychosocial predictors of substance use in adolescents and young adults: Longitudinal risk and protective factors

Many psychosocial factors have been implicated in the onset and escalation of substance use in adolescence and young adulthood. Typically, each factor explains a small amount of the variance in substance use outcomes, and effects are typically applied across a broad range of ages or computed from cross-sectional data. The current study evaluated the association of factors including social influence (e.g., peer substance use), cognitive features (e.g., alcohol expectancies), and personality and emotional characteristics (e.g., impulsivity and typical responses to stress) in substance use throughout adolescence and emerging adulthood (ages 13-25; N = 798). Mixed-effects models tailored for the accelerated longitudinal design employed in this study were constructed with psychosocial and developmental factors predicting alcohol and cannabis use. As most participants in the sample exhibited little or no substance use at baseline by design, we excluded baseline assessments and examined data from follow-up years 1, 2, 3, and 4. Interactions between age cohort, change in age, and psychosocial predictors of substance use revealed differing associations over the developmental window for alcohol and cannabis use. For example, positive alcohol expectancies and sensation seeking were most strongly associated with greater drinking after age 18, whereas sensation seeking was associated with increased cannabis use as early as age 15. Higher emotion regulation skills led to less cannabis use in younger ages (i.e., shallower slopes below age 17), but this protective effect diminished after age 17. Results highlight developmentally important factors that differentially contribute to substance use in adolescence and young adulthood. We also demonstrate the importance of developmentally sensitive analyses that maximize the value of data from accelerated longitudinal designs.

Reward drinking and naltrexone treatment response among young adult heavy drinkers

AIMS

Theory-driven, exploratory study to: (i) identify a reward drinking phenotype in young adults; (ii) evaluate this phenotype as a predictor of naltrexone response; and (iii) examine mechanisms of naltrexone in reward drinkers.

DESIGN

Secondary analysis of a randomized controlled trial.

SETTING

USA.

PARTICIPANTS

A total of 128 young adult (ages 18-25) heavy drinkers.

INTERVENTIONS

Naltrexone versus placebo.

MEASUREMENTS

Daily surveys assessed affect, urge, drinking, and context. The Drinking Motives Questionnaire was used to identify phenotypes based on reward (enhancement motives) and relief (coping motives) drinking.

FINDINGS

We identified three profiles: "Low reward/Low relief" (14.1%; low enhancement/low coping motives); "Reward drinkers" (62.2%; high enhancement/low coping motives); and "High reward/High relief" (22.7%; high enhancement/high coping motives). Among reward drinkers (versus low profile), naltrexone significantly reduced percent days drinking to intoxication (blood alcohol concentration [BAC] ≥0.08) (PDI) (d = 0.56; 95% CI [0.17, 0.96]) and percent high intensity drinking days (PHID) (8/10 drinks for women/men) (d = 0.32; 95% CI [0.01, 0.68]). Among the high reward/high relief profile drinkers (versus low profile), naltrexone reduced PHID (d = 0.69; 95% CI [0.02, 1.50]). Using profile-informed cutoffs and observed scores (for clinical applicability): (i) among cutoff-derived reward drinkers, we found a medium-to-large (d = 0.66; 95% CI [0.24, 1.16]) and small effect (d = 0.28; 95% CI [0.04, 0.72]) of naltrexone in reducing PDI and PHID, respectively; and (ii) among the cutoff-derived high reward/high relief subgroup, we found a medium-to-large effect (d = 0.63; 95% CI [0.05, 1.1]) of naltrexone in reducing PHID. Among reward drinkers (not other profiles), naltrexone reduced drinking on days a drinking event occurred by weakening the within-day association between positive affect and urges (P < 0.05).

CONCLUSIONS

Naltrexone has pronounced effects in reducing risky drinking among young adult reward drinkers (high reward/low relief) by reducing urges on days when individuals have higher positive affect and are exposed to a drinking event. Naltrexone also appears to reduce risky drinking among young adult high reward/high relief drinkers, but not via the same mechanism.

Enhanced Brief Motivational Intervention for College Student Drinkers With ADHD: Goal-Directed Activation as a Mechanism of Change

College students with attention-deficit/hyperactivity disorder (ADHD) are at risk for alcohol-related problems and disorders relative to their typically developing peers. Despite risk, the optimal therapeutic approach for reducing problem alcohol use in students with ADHD, and mechanisms of change underlying treatment effects in this population, are largely unknown. The current study evaluated putative mechanisms of change in a randomized controlled trial of two harm reduction interventions for college student drinkers with ADHD (N = 113; 49% male): brief motivational intervention plus supportive counseling (BMI + SC) versus brief motivational intervention plus behavioral activation (BMI + BA). Results showed that participants in the BMI + BA condition engaged in more goal-directed activation and less avoidant behavior over the course of treatment compared to those in the BMI + SC condition, in turn predicting reductions in alcohol-related negative consequences. Effects were more robust 1 month following intervention, and diminished by 3 months. Sensitivity analyses revealed a significant indirect effect of treatment condition on alcohol-related negative consequence via reductions in avoidance over treatment. Post hoc moderated mediations showed that BMI + BA engaged target mechanisms more robustly for students with more severe ADHD and depressive symptoms compared to BMI + SC. These findings support the application of BMI + BA intervention, particularly in targeting goal-directed activation and avoidance/rumination in at-risk student drinkers with ADHD.

Binge Drinking: The Top 100 Cited Papers

We conducted a review to analyze the 100 most-cited studies on binge drinking (BD) in the Web of Science (WoS) database to determine their current status and the aspects that require further attention. We carried out a retrospective bibliometric analysis in January 2021. The year of publication, authors, design, subject, journal, institution and lead author’s country, as well as the definition of BD, were extracted from the articles. The data on the country, year, thematic category of the journals and their rank were obtained from the Institute for Scientific Information (ISI) Journal Citation Reports 2020. The number of citations was collected from the WoS, and the h index was collected from the Scopus database. The citation density and Bradford’s law were calculated. The majority of the articles were empirical quantitative studies with a cross-sectional design published between 1992 and 2013 in 49 journals. There were 306 authors, mostly English-speaking and from the USA. The definitions used to describe BD are not homogeneous. The most-cited topics were the analysis of consequences, determinants and epidemiology. There is a need to unify the definitions of BD and base them on scientific evidence. The multidisciplinary nature of BD is not well reflected in each of the thematic areas discussed in this work.

A randomized iterative approach to optimizing an online substance use intervention for collegiate athletes

BACKGROUND

Rates of drug use among collegiate athletes are high, yet there are few evidence-based interventions for this population. myPlaybook, an online intervention for collegiate athletes, targets multiple predictors of drug use (i.e., norms, positive and negative expectancies about use, and harm prevention intentions).

PURPOSE

We aimed to optimize modules from myPlaybook.

METHOD

We evaluated modules through three sequential randomized factorial trials, using the Multiphase Optimization Strategy framework. We recruited and randomized 54 (Trial 1), 47 (Trial 2), and 42 (Trial 3) schools and invited all first-year and transfer collegiate athletes to participate. Athletes completed a baseline survey, their randomly assigned modules, and immediate posttest and 30-day follow-up surveys. Across trials, 3,244 (48.8% female), 2,837 (51.9% female), and 2,193 (51.4% female) athletes participated. In Trial 1, we evaluated and revised less effective modules (defined as d < 0.3-0.4 for targeted outcomes). In Trial 2, we re-evaluated and revised less effective modules. In Trial 3, we re-evaluated the revised modules.

RESULTS

Trial 1: All effects were d < 0.15, so we revised modules to target proximal outcomes (i.e., the hypothesized mediating variables in our conceptual model), rather than specific drug use behaviors. Trial 2: Most effects were d < 0.3, so we revised all modules. Trial 3: The norms module improved descriptive and injunctive norms (all d >0.35). The expectancies module improved alcohol positive expectancies (d = 0.3). The other modules were not effective.

CONCLUSIONS

After three trials, two myPlaybook modules substantially improved proximal outcomes, increasing the likelihood that the combined intervention will have a meaningful clinical impact on collegiate athletes' drug use.

C.A.R.E.S: A mobile health program for alcohol risk reduction in community college students

BACKGROUND

Compared to students at four-year residential colleges, Community College Students (CCS) are at greater risk for binge drinking and alcohol related risks, however few interventions have been developed specifically for the needs of CCS.

METHODS AND DESIGN

This study design tests the efficacy of a smartphone app (CARES) compared to an existing online alcohol education (AE) program. CCS (n = 250) will be recruited using a nationwide social media campaign and randomly assigned to either arm, stratified by sex and age (over/under 21). Eligibility screening, consent and assessments are conducted online and both interventions are accessible by smartphone. Assessments will be conducted at baseline, 4- and 8- weeks, end of treatment (12-weeks) and at 6-month follow-up. The primary outcomes are heavy episodic drinking (past 2 weeks), and alcohol related problems Confidence in refusing alcohol, use of protective behavioral strategies and expectations regarding alcohol use. Demographics including age, sex, race/ethnicity, marital and parental status and employment will be analyzed as potential covariates.

DISCUSSION

Community colleges serve approximately half of all US college students but frequently lack the resources to implement full-service alcohol prevention and education programs. The specific needs of CCS also differ from those of residential college students for whom most alcohol prevention programs have been developed. If proven efficacious, the CARES intervention may offer a scalable, easily disseminable program designed for the needs of community colleges and their students.

Personality or pathology? Predictors of early substance use in first-year college students

OBJECTIVE

The aim of the current study was to examine the dual role of personality and psychopathology in predicting substance use among first-year students.

PARTICIPANTS

103 first-semester undergraduate students were recruited via the university subject pool.

METHODS

Participants completed personality questionnaires, structured clinical interviews, followed by the completion of diary entries each week reporting on substance use throughout their first semester.

RESULTS

Results indicated that a past diagnosis of an affective (mood/anxiety/stress) disorder was the most significant predictor of substance use. Personality and current psychopathology had no association to substance use.

CONCLUSION

This finding is consistent with developmental models of substance use relating to emotion-related disease and suggests that greater nuance is needed in understanding substance use risk in college students.

Dissemination of a Universally Delivered Brief Alcohol Intervention in United States Air Force Technical Training

OBJECTIVES

Heavy alcohol use is a particular problem in the US military, prompting the Institute of Medicine to identify it as a public health crisis. Developing prevention programs aimed at reducing problematic drinking during military service would be useful. Thus, the purpose of the current study, was to broadly disseminate and assess the effectiveness of a brief alcohol intervention (BAI) + random breathalyzer (RB) intervention to reduce alcohol related incidents (ARIs), to all incoming Air Force trainees.

METHODS

The BAI was administered to all incoming Airmen (N = 15,898) across 4 major training Air Force bases. Additionally, underage Airmen were subject to RB tests. A quasi-experimental pre-test post-test design compared the rate of ARIs, per 100,000 training days, during the year prior and the year after the intervention was delivered.

RESULTS

A Poisson model indicated that the BAI + RB intervention was associated with a decrease in ARIs across all bases. Overall, the intervention lowered the ARI rate by 16% (β = -0.178, standard error  = 0.0742, P = 0.016). For every 100,000 training days, annual ARIs decreased from 30.8 to 25.5 after implementation.

CONCLUSIONS

A universally administered brief alcohol intervention, coupled with RB targeting underage drinkers, was associated with a reduction in the rate of ARIs. Results of this large-scale prevention study indicate that a brief alcohol intervention can be widely disseminated during US Air Force training and can perhaps reduce costs and make a public health contribution by decreasing alcohol related incidents.

Prescription Tranquilizer/Sedative Misuse Motives Across the US Population

OBJECTIVES

Roughly 6.5 million US residents engaged in prescription tranquilizer/sedative (eg, benzodiazepines, Z-drugs) misuse in 2018, but tranquilizer/sedative misuse motives are understudied, with a need for nationally representative data and examinations of motives by age group. Our aims were to establish tranquilizer/sedative misuse motives and correlates of motives by age cohort, and whether motive-age cohort interactions existed by correlate.

METHODS

Data were from the 2015 to 2018 US National Survey on Drug Use and Health, with 223,520 total respondents (51.5% female); 6580 noted past-year prescription tranquilizer/sedative misuse motives (2.4% overall, 50.3% female). Correlates included substance use (eg, opioid misuse), mental (eg, suicidal ideation) and physical health variables (e.g., inpatient hospitalization). Design-based, weighted cross-tabulations and logistic regression analyses were used, including analyses of age cohort-motive interactions for each correlate.

RESULTS

Prescription tranquilizer/sedative misuse motives varied by age group, with the highest rates of self-treatment only motives (ie, sleep and/or relax) in those 65 and older (82.7%), and the highest rates of any recreational motives in adolescents (12-17 years; 67.5%). Any tranquilizer/sedative misuse was associated with elevated odds of substance use, mental health, and physical health correlates, but recreational misuse was associated with the highest odds. Age-based interactions suggested stronger relationships between tranquilizer/sedative misuse and mental health in adults 50 and older.

CONCLUSIONS

Any tranquilizer/sedative misuse signals a need for substance use and mental health screening, with intervention needs most acute in those with any recreational motives. Older adult tranquilizer/sedative misuse may be more driven by undertreated insomnia and anxiety/psychopathology than in younger groups.

Effects of a cannabis use disorder text message-delivered treatment on young adult alcohol misuse: Differential effects by gender

Alcohol misuse is more prevalent, frequent, and severe among young adults who use cannabis. Treatment of dual alcohol and cannabis users may have mixed results, with some studies reporting that alcohol misuse increases when cannabis use decreases (substance substitution), while others report that alcohol misuse decreases along with decreasing cannabis use (treatment spillover), and others report no association. Additionally, little research tests whether gender differences are found in treatment of dual alcohol and cannabis users, which may be expected given previous alcohol-focused treatments showing larger effects for females. In the current study, we present a secondary analysis of a randomized clinical trial testing a text message-delivered cannabis use disorder (CUD) treatment (peer network counseling text or "PNC-txt"). The trial included 101 young adults ages 18-25 who met criteria for CUD. We tested whether alcohol use and binge drinking frequency (4+/5+ drinks for women/men) decreased in response to the PNC-txt treatment, which has previously shown effectiveness in reducing cannabis use days. Latent growth models tested PNC-txt effects on the monthly rate of change in alcohol use and binge drinking across three months. In the full sample, we found no evidence of significant treatment effects on alcohol use (d = -0.07) or binge drinking (d = -0.10). Moderation analyses, however, indicated the PNC-txt effect on both alcohol use and binge drinking differed significantly by gender. PNC-txt led to significantly larger decreases in alcohol use (d = -0.53) and binge drinking days (d = -0.43) across the three months for females, whereas the study saw opposite (but nonsignificant) effects for males (d = 0.30 and 0.16 for alcohol use and binge drinking, respectively). We found no evidence that reductions in alcohol use and binge drinking were associated with cannabis use decreases, arguing against direct substitution or spillover effects. These results provide evidence that treatments focused on cannabis use may have secondary beneficial effects for young-adult alcohol misuse, although such effects may be limited to women.
