Insomnia treatment effects on negative emotionality among veterans in treatment for alcohol use disorder.

BACKGROUND: Insomnia symptoms are pervasive and persistent in alcohol use disorder (AUD), though little is known about the mechanisms that underlie this association. We previously found that cognitive behavioral therapy for insomnia (CBT-I) reduced alcohol-related problems among veterans by improving insomnia severity (NCT03806491). In this planned secondary analysis of the same clinical trial data, we tested negative emotionality as one potential mechanism to explain this effect. Specifically, we tested the change in negative emotionality as a mediator of the association between change in insomnia symptoms and alcohol-related outcomes (craving, heavy drinking frequency, and alcohol-related problems). METHODS: Participants were 67 veterans in treatment for AUD who also met the criteria for insomnia disorder (91% male, 84% White, average age = 46.3 years). Participants were randomized to five sessions of CBT-I or a single-session sleep hygiene control. Assessments occurred at baseline, immediately posttreatment (~6 weeks after baseline), and at 6-week follow-up. Measures included the Insomnia Severity Index, Penn Alcohol Craving Scale, Timeline Followback, and Short Inventory of Problems. We created a latent negative emotionality indicator based on five validated and reliable measures of negative emotionality. RESULTS: Contrary to hypotheses, CBT-I did not improve negative emotionality relative to sleep hygiene control. However, across both treatment conditions, decreases in insomnia symptoms from baseline to posttreatment were associated with concurrent decreases in negative emotionality, which in turn predicted reductions in alcohol craving and heavy drinking. CONCLUSION: Negative emotionality may help explain links between insomnia symptoms and alcohol-related outcomes.

Feeling in control in sexual situations: Day-level associations with alcohol use and alcohol protective behavioral strategies.

BACKGROUND: Feeling in control in a sexual situation may vary as a function of contextual factors, such as whether alcohol is used prior to a sexual experience. Alcohol protective behavioral strategies (PBS) reduce adverse alcohol-related outcomes and may promote greater sense of control in sexual situations. It was hypothesized that, at the day level, (1) greater alcohol use would be associated with lower likelihood of feeling in control in sexual situations, (2) more PBS would be associated with a greater likelihood of feeling in control, and (3) more PBS would weaken the negative association between alcohol use and sexual control. METHODS: For 28 days, daily data on feeling in control during sex, number of drinks, and PBS were collected from young adults who engage in high-intensity drinking (8+/10+ drinks in a sitting for women/men). A sample of 112 young adults (age 18-29, 61% female; 78.6% White; 9.8% Hispanic/Latino) reported sex after alcohol use at least once (n = 322 days total). Alcohol use, PBS (total as well as subtype: stopping/limiting drinking [SLD], manner of drinking [MD], and serious harm reduction [SHR]), and alcohol use by PBS interactions were tested as day-level correlates of sexual control via hierarchical generalized linear modeling. RESULTS: A significant interaction between alcohol and total PBS on control was observed. At low levels of PBS, more drinks were related to lower likelihood of feeling in control during sex. At high levels of PBS, number of drinks was unrelated to control. A similar pattern of results was observed when examining the PBS subscale of SLD. No main effects of daily PBS or alcohol use on control were observed. CONCLUSIONS: Findings provide insight into feeling in control when drinking alcohol and engaging in sex, at varying levels of PBS. Interventions focused on harm reduction strategies have the potential to reduce risk of alcohol-related adverse sexual experiences.

An exploratory analysis of drinking motives and alcohol-related problems among Hispanic college students.

The increase in college enrollment for Hispanic college students warrants increased attention to their health and wellness. Given that a common threat to health and well-being in college students is alcohol use and that Hispanic college students are at elevated risk for alcohol-related problems, it is essential to investigate factors that might lead to heightened alcohol-related problems among this population. The present study is a secondary data analysis of an NIAAA-funded study investigating brief interventions for alcohol use among 583 heavy-drinking college students. Specifically, we examined the relationship between Hispanic student status and alcohol-related problems measured one month later. Additionally, we examined the indirect effects of Hispanic status on alcohol-related problems through drinking motives. Analyses revealed a significant association between Hispanic status and alcohol-related problems at baseline but no association between Hispanic status and problems at 1-month, controlling for baseline problems. An indirect effect of the prospective association between Hispanic student status and alcohol-related problems was evident for only one of the four drinking motives (coping). Our findings suggest that reducing coping motives for drinking among Hispanic college students may reduce alcohol-related problems.

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.

Do hypothetical evaluations of alcohol related consequences change over time? Examining the influence of past and ongoing consequences.

OBJECTIVE: Despite experiencing alcohol-related consequences, college students continue to drink at high rates. Hypothetical evaluations of alcohol-related consequences (i.e., evaluations of where potential/hypothetical consequences lie on a spectrum from extremely positive to extremely negative) may contribute to the maintenance of drinking patterns among students. The purpose of the present study was to describe hypothetical evaluations in a sample of students mandated to an alcohol intervention, examine changes over time, and investigate the influence of both baseline and time-varying experienced consequences. METHOD: This study was a secondary data analysis from a longitudinal randomized controlled trial. Participants were 474 mandated students (Mage = 18.65; 55.5 % male, 77.6 % White). Students completed an initial baseline assessment of demographics, alcohol use, consequences, and hypothetical evaluations, and 3-month and 9-month follow-up assessments that included hypothetical evaluations and experienced consequences. RESULTS: Hierarchical linear modeling (HLM) analyses revealed significant change in hypothetical evaluations over time such that they became less negative. A piecewise model demonstrated that this change happened between baseline and 3-month, with no additional change between 3-month and 9-month. The experience of consequences at baseline did not significantly moderate changes in either time interval. Time-varying consequences also had no significant effect on same-timepoint hypothetical evaluations. CONCLUSIONS: This study is the first to examine changes in hypothetical evaluations over time among mandated college students. Counter to expectations, hypothetical evaluations became less negative at 3-month follow-up. Though preliminary, findings add to the understanding of hypothetical evaluations of alcohol-related consequences.

World Health Organization Risk Drinking Levels Among Mandated College Students: Associations With Alcohol Use, Mental Health, and Academic Performance.

OBJECTIVE: World Health Organization (WHO) risk drinking levels (i.e., low, moderate, high, or very high risk) have been used as a drinking-reduction endpoint in clinical trials. Yet, prior work has not attempted to quantify reductions in WHO risk levels among mandated students, who may also benefit from reduced drinking. We sought to validate WHO risk drinking levels in differentiating students' alcohol-related outcomes, depressive symptoms, and academic performance. Defining risk via typical drinks per drinking day versus drinks per day was compared, and gender differences were examined. METHOD: Baseline data were drawn from three intervention trials for students mandated to intervention and who were not abstinent (N = 1,436). Sex-specific WHO risk levels were generated and dummy coded, with low risk as the reference. Regression models examined associations of risk levels with positive Alcohol Use Disorders Identification Test (AUDIT) scores, peak drinking, consequences, depressive symptoms, and grade point average. RESULTS: Defining WHO risk via drinks per drinking day evenly dispersed students across categories, whereas drinks per day categorized most students as low risk. More women than men were classified as very high risk across definitions. Students classified as low risk differed from those classified as moderate, high, and very high risk in screening positive on the AUDIT, peak drinking, and consequences. WHO risk levels did not differentiate depressive symptoms. Differences in grade point average were inconsistent across risk definitions. CONCLUSIONS: WHO risk drinking levels differentiated alcohol use and consequences and, therefore, hold promise for clinical use and for quantifying drinking reductions among mandated college students.

Does self-affirmation augment the effects of a mandated personalized feedback intervention? A randomized controlled trial with heavy drinking college students.

OBJECTIVE: Theory and evidence indicate that affirming the value of the self before exposure to a threatening message fosters more open-minded appraisal of message content. We predicted that college students mandated to a computer-delivered personalized feedback intervention (PFI) and who engaged in a self-affirmation (SA) exercise would demonstrate reduce drinking and consequences relative to those who received an attention control. METHOD: Participants were 484 undergraduates (age 18-24, 56% male, 78% White) mandated to participate in an alcohol intervention following a first-time alcohol policy violation. After a baseline assessment, each was randomized to SA (n = 256) or attention control (n = 227) prior to a computer-delivered PFI intervention. Posttest measures included an affirmation manipulation check; primary outcomes (past month weekly quantity, peak drinks, binge frequency, consequences) were assessed at 1-, 3-, 6-, 9-, and 12-month follow-ups. We used latent growth curve modeling to test study hypotheses. RESULTS: The SA exercise increased positive self-evaluation at posttest (p < .001). Overall reductions in drinking and consequences were observed at early follow-up (all p < .05), but the SA manipulation was not associated with intercept or slope factor differences in the models. Engaging in assessments during COVID restrictions was generally associated with reduced drinking and consequences. CONCLUSIONS: The SA exercise did not differentially affect trajectories of alcohol use and consequences, despite evidence that the exercise had the predicted effect on participant's self-evaluations. The lack of SA effects could be attributed to a nonthreatening PFI intervention that is generally accepted among mandated students. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

How Do Bystanders Help in Drinking Situations: The Bystanders to Alcohol Risk Scale--Strategies.

OBJECTIVE: Bystander intervention (BI) is a promising approach for promoting collective behavior change that has been applied to several domains, including sexual assault, bullying, and more recently, problematic alcohol use. Accurately measuring the strategies that bystanders use to reduce others' alcohol-related risk is an essential step toward improving bystanders' ability to reduce alcohol-related harm in their communities, but current measures of BI are not easily modifiable and applicable for alcohol-related BI. The current study aimed to develop a valid and reliable measure of the bystander construct most proximal to the reduction of risk: bystander strategies. METHOD: Young adults (N = 1,011) who reported being around someone who showed signs of alcohol intoxication in the past 3 months were recruited via Qualtrics Panels to participate in an online survey; a subsample (n = 345) completed a 2-week follow-up. Psychometric evaluation included exploratory and confirmatory factor analyses, item response theory analyses, convergent validity, and test-retest reliability. RESULTS: An initial set of 52 items was reduced to 17 items, representing two different factors. The first factor, Level 1, reflected strategies used during circumstances of acute risk. The second factor, Level 2, reflected strategies used to reduce risk for more longstanding problems with alcohol. Both factors demonstrated good model fit, strong internal consistency, evidence of convergent validity, and moderate test-retest reliability. CONCLUSIONS: This novel measure can contribute to the production of knowledge about the use and efficacy of peer-focused strategies and the value of BI training for alcohol use.

Characterizing Alcohol Consumption and Positive and Negative Consequences During Simultaneous Alcohol and Cannabis Use Events.

OBJECTIVE: Young adults who engage in simultaneous alcohol and cannabis use report heavy use of both substances. Event-level studies examining differences between consequences experienced on simultaneous use compared with single substance use days have been mixed. Although studies often control for alcohol use levels, few have examined how quantity of alcohol may influence consequences experienced on simultaneous use days. Furthermore, little research has examined the relationship between simultaneous use and positive consequences or explored individual consequences. This study examined differences in consequences experienced on simultaneous use versus single substance use days (alcohol-only, cannabis-only) including endorsement of specific consequences and examined the relationship among simultaneous use, consequences, and alcohol consumption. METHOD: Young adults who engage in simultaneous use (N = 86) completed 30 days of daily surveys reporting substance use and positive and negative consequences. RESULTS: Simultaneous use days were associated with more negative and positive consequences than single substance use (alcohol-only and cannabis-only) days. We also examined endorsement of specific positive and negative consequences on alcohol-only, cannabis-only, and simultaneous use days. The effect of day type (simultaneous use vs. alcohol-only) on consequences was moderated by alcohol quantity. On lighter drinking days, more positive and negative consequences were endorsed if it was a simultaneous use versus alcohol-only day. On heavier drinking days, number of consequences did not differ between simultaneous use and alcohol-only days. CONCLUSIONS: Findings from this study point to simultaneous use as both reinforcing and high risk and highlight the importance of intervening even on lighter drinking simultaneous use occasions to reduce harms.

Measuring Exposure to the Hazardous Drinking of Others and Perceived Opportunity to Intervene as a Bystander.

OBJECTIVE: Excessive alcohol use is very prevalent among young adults, and consequences of drinking are often observed by witnesses. Understanding the circumstances under which witnesses of risky alcohol use help others and whether they perceive these circumstances as an opportunity to engage in bystander intervention are important, but valid measures of these constructs are needed. The current study is a psychometric evaluation of the Exposure to Hazardous Drinking in Others (EHDO) scale and a single-item indicator of Perceived Alcohol-Related Bystander Opportunity (PARBO). METHOD: Young adults (N = 1,011; 46.0% women) who reported being around someone who showed signs of alcohol intoxication in the past 3 months were recruited via Qualtrics Panels. The initial item set for the EHDO was developed through qualitative methods and reflected observed or reported risks or consequences. Factor analyses and Item Response Theory analyses were used to reduce and categorize EHDO items, and construct validity was assessed for the EHDO and the PARBO item. RESULTS: An initial set of 33 EHDO items was reduced to 21, representing two factors: Situational Risk Signs and Problematic Pattern. Both factors demonstrated good model fit, internal consistency, and evidence of convergent validity. The PARBO item showed good construct validity but was distinct from the EHDO. CONCLUSIONS: These instruments are useful for measuring secondhand alcohol risks in a community and are particularly applicable for evaluating bystander intervention for alcohol risk.

Perceived belonging on campus predicts depression among heavy drinkers: A test of three moderators.

Objective: An association exists between perceived belonging and depression among college students. Because a student's sense of belongingness may vary as a function of their social identity, three identities - ethnicity, first-generation college student status, and sex - were investigated as potential moderators of this relationship. Participants: One hundred eighty-seven heavy-drinking college students (63% female; 52% non-Latinx White; M = 20 years of age) were assessed. Methods: Three hierarchical linear regressions were conducted to test whether belonging at baseline predicted depression at six months and whether each identity variable moderated this association. Results: Analyses yielded significant main effects between belonging and depression. Hispanic nor first-generation status interacted with belonging in predicting depression. Sex interacted with belonging where higher belongingness was associated with lower levels of depression only among female students. Conclusion: Mental health providers should consider asking female students about their perceptions of belonging on college campuses to understand their vulnerability to depression.

Low levels of fitting in on campus moderates the relationship between enhancement drinking motives and drinks per week among college students.

The first year of college is often marked by increased levels of alcohol consumption; first-year students also vary in their sense of fitting in on campus. Research has amply documented the links between social and enhancement drinking motives with various alcohol outcomes among college students. However, it is unclear how perceived levels of fitting in on campus potentially buffers or amplifies the relationship between drinking motives and drinking behavior. We explored whether perceptions of fitting in on campus moderated effects of social and/or enhancement drinking motives on drinks per week. A sample of 121 heavy drinking first year college students (50 % female, 58 % non-Latinx White, M = 18 years of age) were assessed twice in their first semester (baseline, 3 months) in the context of an alcohol-specific intervention. Hierarchical linear regressions were conducted to test whether drinking motives (social and enhancement) at baseline prospectively predicted drinks per week at 3 months. We hypothesized a positive association between both drinking motives and drinks per week; whether fitting in moderates these relationships was exploratory. Regression analyses yielded non-significant main effects of social motives, enhancement motives, and feelings of fitting in on drinks per week. There was no significant interaction for social motives, but the interaction between enhancement motives and fitting in was significant. Participants with a low sense of fitting in had a strong positive relationship between enhancement motives and drinks per week. Improving perceptions of fitting in for first-year college students may potentially reduce the association between enhancement drinking motives and drinks per week.

Effect of Cognitive Behavioral Therapy for Insomnia on Alcohol Treatment Outcomes Among US Veterans: A Randomized Clinical Trial.

Importance: Three of 4 adults in treatment for alcohol use disorder (AUD) report symptoms of insomnia. Yet the first-line treatment for insomnia (cognitive behavioral therapy for insomnia, CBT-I) is often delayed until abstinence is established. Objective: To test the feasibility, acceptability, and preliminary efficacy of CBT-I among veterans early in their AUD treatment and to examine improvement in insomnia as a mechanism for improvement in alcohol use outcomes. Design, Setting, and Participants: For this randomized clinical trial, participants were recruited through the Addictions Treatment Program at a Veterans Health Administration hospital between 2019 and 2022. Patients in treatment for AUD were eligible if they met criteria for insomnia disorder and reported alcohol use in the past 2 months at baseline. Follow-up visits occurred posttreatment and at 6 weeks. Interventions: Participants were randomly assigned to receive 5 weekly sessions of CBT-I or a single session about sleep hygiene (control). Participants were asked to complete sleep diaries for 7 days at each assessment. Main Outcomes and Measures: Primary outcomes included posttreatment insomnia severity (assessed using the Insomnia Severity Index) and follow-up frequency of any drinking and heavy drinking (4 drinks for women, ≥5 drinks for men; number of days via Timeline Followback) and alcohol-related problems (Short Inventory of Problems). Posttreatment insomnia severity was tested as a mediator of CBT-I effects on alcohol use outcomes at the 6-week follow-up. Results: The study cohort included 67 veterans with a mean (SD) age of 46.3 years (11.8); 61 (91%) were male and 6 (9%) female. The CBT-I group included 32 participants, and the sleep hygiene control group 35 participants. Of those randomized, 59 (88%) provided posttreatment or follow-up data (31 CBT-I, 28 sleep hygiene). Relative to sleep hygiene, CBT-I participants reported greater decreases in insomnia severity at posttreatment (group × time interaction: -3.70; 95% CI, -6.79 to -0.61) and follow-up (-3.34; 95% CI, -6.46 to -0.23) and greater improvements in sleep efficiency (posttreatment, 8.31; 95% CI, 1.35 to 15.26; follow-up, 18.03; 95% CI, 10.46 to 25.60). They also reported greater decreases in alcohol problems at follow-up (group × time interaction: -0.84; 95% CI, -1.66 to -0.02), and this effect was mediated by posttreatment change in insomnia severity. No group differences emerged for abstinence or heavy-drinking frequency. Conclusions and Relevance: In this randomized clinical trial, CBT-I outperformed sleep hygiene in reducing insomnia symptoms and alcohol-related problems over time but had no effect on frequency of heavy drinking. CBT-I should be considered a first-line treatment for insomnia, regardless of abstinence. Trial Registration: ClinicalTrials.gov Identifier: NCT03806491.

Applying the prototype willingness model to day-level simultaneous alcohol and cannabis use.

OBJECTIVE: The prototype willingness model (PWM) provides a framework for understanding simultaneous alcohol and cannabis use by highlighting important psychosocial (e.g., attitudes, norms) predictors of and pathways (via willingness and/or intentions) to simultaneous use. We examined both the PWM reasoned and social reaction pathways in relation to simultaneous use. METHOD: Eighty-nine young adults self-monitored alcohol, cannabis, and simultaneous use and related constructs for 30 days via daily assessments. RESULTS: Day-level simultaneous use specific attitudes, norms, perceived vulnerability, intentions, and willingness each predicted simultaneous use, while only day-level intentions and willingness predicted number of negative consequences. We observed significant indirect effects for the two social reaction pathways examined (from descriptive norms to willingness to simultaneous use; from perceived vulnerability to willingness to simultaneous use). Only direct effects were seen for the cognitions in the reasoned pathway; injunctive norms predicted simultaneous use, and attitudes predicted simultaneous use with no mediation by intentions. CONCLUSIONS: Findings support applying the PWM to event-level simultaneous use among young adults. Future work should establish if PWM day-level constructs are modifiable targets that may be utilized in intervention work focused on reducing simultaneous use and related harms.

Examining Attitude, Norms, and Intentions as Predictors of Prospective Change in Alcohol-Induced Blackouts.

OBJECTIVE: Alcohol-induced blackouts are a marker of risk such that they are strong independent predictors of experiencing other adverse alcohol-related social and health effects. Existing work informed by the Theory of Planned Behavior suggests that several of the constructs contained within it, such as perceived norms, personal attitudes toward consumption, and drinking intentions, are reliable predictors of alcohol use, related problems, and blackout experiences. However, research to date has not examined these theoretical antecedents as predictors of change in the occurrence of alcohol-induced blackout. The current work aimed to evaluate descriptive (the rate a behavior occurs) and injunctive (the approval of a behavior) norms, attitudes toward heavy drinking, and drinking intentions as predictors of the prospective change in experiencing a blackout. METHOD: Using existing data from two samples (Sample 1: N = 431, 68% male; Sample 2: N = 479, 52% male), students mandated to complete an alcohol intervention completed surveys at baseline and 1- and 3-month follow-ups. Latent growth curve models evaluated perceived norms, positive attitude toward heavy drinking, and drinking intention as prospective predictors of the change in blackout over 3 months. RESULTS: Across both samples, descriptive and injunctive norms and drinking intentions were not significantly predictive of the change in blackout. Only attitude toward heavy drinking significantly predicted prospective change (the slope factor) in blackout in both samples. CONCLUSIONS: Given the strong association between heavy drinking attitudes and change in blackout, attitudes may represent an important and novel target for prevention and intervention efforts.

Religion and drinking: Differences between two campuses.

Levels of religiousness vary by geographic location, but studies of the relationship between religiousness and alcohol are often limited to one region. For our participants (N = 1124; 57.5% female), location was significantly associated with both religiousness and alcohol use. Active religiousness was associated with drinking outcomes. The indirect effects of location on drinks per week through active religiousness were significant. At Campus S, subjective religiousness was associated with more drinks per week, whereas active religiousness was associated with fewer drinks per week. Findings indicate active religiousness is especially relevant when exploring drinking, and location is important when exploring religiousness and alcohol use.

A qualitative examination of the decision-making process of simultaneous alcohol and cannabis use: Intentions and willingness.

BACKGROUND: Alcohol and cannabis use are common among young adults and most young adults who use both substances have used them simultaneously (i.e., using both substances so their effects overlap). Because simultaneous use is associated with a greater number and severity of consequences than single substance use, research is needed to examine the decision-making process of engaging in this high-risk behavior. We conducted a qualitative examination of intentions (i.e., plans) and willingness (i.e., one's openness to engage in the behavior if an opportunity presents itself) to engage in simultaneous use from the perspective of young adults who frequently report this substance use behavior. METHODS: We recruited 36 young adults who reported simultaneous use and heavy drinking (4+/5+ drinks for women/men; 64% women, ages 18 to 25) to participate in semi-structured interviews. All interviews were double coded for thematic analysis and both novel and a priori themes were found. RESULTS: Young adults distinguished between intending to engage in simultaneous use and being willing to engage in simultaneous use. They reported that intentions and willingness varied from occasion to occasion. They also reported that context and alcohol consumption influenced their willingness to engage in simultaneous use. Peer pressure or offers increased their willingness to use cannabis while drinking and having current or next-day responsibilities decreased their willingness to engage in simultaneous use. Additionally, planned simultaneous use occasions were characterized as being special events where young adults consumed more substances, but were more likely to monitor their use than unplanned occasions. CONCLUSIONS: Intentions and willingness may be important proximal predictors of simultaneous use of alcohol and cannabis. Building off this qualitative work, quantitative research should identify which factors influence the decision-making process to engage in simultaneous use and determine when intentions and willingness are most predictive of risky simultaneous use behavior.

Where do heavy drinking college students experience alcohol consequences and where are they perceived to be normative?

High levels of alcohol consumption are common among college students and associated with endorsing negative alcohol-related consequences. Research suggests both drinking norms and location are strong predictors of drinking behavior in college students. Yet, normative perceptions of consequences, and whether they are location-specific, are less well-studied. We tested the hypotheses that college students who drink would have the highest levels of descriptive and injunctive norms for negative consequences, and would self-report the greatest number of negative consequences, at large gatherings/parties relative to someone's home/dorm and/or bars/clubs. Additionally, we explored whether specific acute consequences were more likely in some drinking locations versus others. Participants were 96 full-time undergraduate students who engaged in high-risk drinking. At baseline, participants reported descriptive and injunctive norms for negative consequences in three locations (home/dorm, large gathering/party, bar/club). Over a 28-day period, participants self-reported daily experiences of five alcohol-related consequences in these same locations. With repeated measures analyses of variance, we found that participants perceived their peers experienced more negative consequences and were more approving of negative consequences at large gatherings/parties and small gatherings at someone's home/dorm relative to bars/clubs. Likewise, nonparametric analyses demonstrated that the total number of consequences over the 28-day assessment period also differed by location, with participants reporting more consequences at home/dorm and large gathering/party locations than at bars/clubs. Future research is needed to better understand how the impact of norms on behavior differs across drinking location, and whether location-specific intervention content (e.g., normative correction) would be useful.

Criterion Validity of Protective Behavioral Strategies for Alcohol Consumption among College Students: Comparison across Two Measures.

BACKGROUND: Protective behavioral strategies (PBS), or behaviors used to reduce harm associated with alcohol use, are often associated with lower levels of alcohol consumption, lower engagement in high-risk drinking behaviors, and fewer alcohol-related consequences. Although the majority of studies have found significant associations between higher PBS use and lower consumption or consequences, some studies have found nonsignificant or even positive associations. One explanatory hypothesis is that the mixed findings are due to differential content in PBS measures. OBJECTIVES: The current study examined the criterion validity of two widely-used PBS measures, the PBSS and the SQ. In a multi-institution online study assessing alcohol outcomes, college drinkers were randomly assigned to complete one PBS measure. Both measures had the same response options to standardize assessment and focus on content. RESULTS: Findings suggest both measures of PBS are consistently predictive of alcohol outcomes among college drinkers, across multiple subpopulations (i.e., strength of association was not moderated by sex, race, or drinking level). CONCLUSIONS/IMPORTANCE: Some PBS subscales were more impactful than others, suggesting researchers may want to choose which PBS scale to use based on outcomes of interest, or after determining if alternatives to drinking is an important facet of PBS for the research questions being examined. Moreover, the differential findings for subscales suggest that prevention and intervention programs incorporating PBS should focus on strategies that avoid high-risk scenarios (e.g., avoiding shots or drinking games), rather than general strategies of self-pacing.

Real-time and next-morning correlates of subjective alcohol consequence evaluations.

OBJECTIVE: There is considerable variation in how college student drinkers evaluate alcohol-related consequences across time and consequence type. Previous qualitative work suggested that students perceive consequences less negatively under certain circumstances (i.e., higher intoxication, when less time has passed, positive mood, after discussing with friends). The present study sought to confirm these patterns, using ecological momentary assessment (EMA) during drinking episodes paired with retrospective next-day assessments. METHOD: For 28 days, heavy-drinking college students (n = 90, 50% female) completed self-reports during drinking episodes and the next morning. Measures included alcohol use, subjective intoxication, mood, negative consequences (e.g., being aggressive) and positive consequences (e.g., new friend), and consequence-specific evaluations. RESULTS: Consistent with hypotheses, multilevel models revealed that during drinking events compared to the next morning, average evaluations of negative and positive consequences were less negative and more positive, respectively. During drinking events, neither subjective intoxication nor estimated blood alcohol concentration (eBAC) was associated with positive or negative evaluations. In morning reports, more positive mood was associated with less negative evaluations of negative consequences and more positive evaluations of positive consequences. Next-day discussion with friends was not significantly associated with consequence evaluations. CONCLUSIONS: This study is the first to assess subjective consequence evaluations in real time as well as retrospectively, for the same events. Findings continue to support the role of context (timing, mood) on subjective consequence evaluations, and suggest that ecological momentary interventions targeting alcohol consequences and related cognitions might best be delivered the morning after drinking, to capitalize on relatively more negative perceptions of one's drinking experiences.
