The way one thinks affects the way one drinks: subjective evaluations of alcohol consequences predict subsequent change in drinking behavior

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.

Shame and guilt for alcohol-related transgressions and hazardous drinking among male and female college students

Objective: Shame and guilt are often present prior to and consequent to alcohol use among college students. Little is known about the propensity to experience these emotions in the context of transgressions that occur while drinking alcohol. We examined the association between shame and guilt propensity for alcohol-related transgressions with hazardous drinking, and the role of gender in these relationships. Participants: College student drinkers (N = 130; Mage=19.39; 68% females; 86% White) from a Mid-south college. Methods: An online confidential survey included measures of hazardous drinking, guilt and shame propensity, and guilt and shame propensity specific to alcohol-related transgressions. Results: Our preliminary findings suggest that experiencing guilt (but not shame) after alcohol-related transgressions was related to less hazardous drinking when controlling for general guilt and shame propensity for male and female students. Conclusions: Targeting components of guilt (e.g., reparative behaviors) after alcohol-related transgressions may help to reduce problematic drinking among college students.

A qualitative examination of positive and negative consequences young adults experience from simultaneous alcohol and cannabis use

OBJECTIVE

Alcohol and cannabis are two of the most commonly used substances among young adults, and most individuals who use both substances use them simultaneously, that is, on the same occasion such that their effects overlap. Given the high prevalence of simultaneous alcohol and cannabis use, it is important to understand the relationship between simultaneous use and consequences. This study presents a qualitative examination of positive and negative consequences of simultaneous use.

METHOD

We conducted individual interviews among 36 young adults who engage in simultaneous use (23 women, 12 men, 1 trans man). Interviews included open-ended questions examining negative and positive consequences of simultaneous use and how simultaneous use differed from single substance use (alcohol only use, cannabis only use). Interviews were analyzed using applied thematic analysis.

RESULTS

Young adults reported numerous negative and positive consequences of simultaneous use, many overlapping with single substance use. Yet, they also reported unique combinations of positive consequences not experienced by single substance use. Young adults discussed patterns of use that were sometimes approached intentionally (e.g., quantity of substances used, order) that influenced consequences.

CONCLUSIONS

Together these findings provide further insight into young adults' simultaneous use experiences. Next steps should include quantitative exploratory research to identify and determine the frequency of specific consequences experienced during simultaneous use and examine the relationship between simultaneous use consequences and particular patterns of use.

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.

Classifying risky cannabis involvement in young adults using the Marijuana Consequences Questionnaire (MACQ)

BACKGROUND

Despite the growing prevalence of cannabis use and associated consequences among U.S. young adults, relatively little is known about precisely what level of marijuana involvement may be problematic.

METHOD

With this study we sought to identify empirically-derived cut-scores for the Marijuana Consequences Questionnaire (MACQ) that would distinguish among levels of cannabis risk in a sample of young adult college students (N = 496). We also examined how these levels of cannabis risk corresponded to a variety of indicators of cannabis involvement, including frequency of use, intoxication, other measures of cannabis consequences, and indicators of more severe cannabis involvement (e.g., physiological dependence, loss of control over use, cannabis use disorder).

RESULTS

Receiver operating characteristic analyses yielded cutoffs that distinguished among three distinct levels of risk, "Low", "Moderate", and "High". These empirically derived cut scores showed strong overall differentiation among classifications, with good sensitivity and specificity. MACQ-based risk levels were validated across several indices of cannabis involvement. Cutoffs differed across genders.

CONCLUSIONS

Findings offer a new application for the MACQ, allowing for the identification of those at greatest risk. As such, this measure may be used to facilitate appropriately targeted intervention.

Consequences, Motives, and Expectancies of Consumption as Predictors of Binge Drinking in University Women

The increasing presence of women, especially university women, in risky alcohol consumption such as Binge Drinking (BD), which is associated with gender-specific biopsychosocial problems, makes it necessary to analyze the variables underlying BD in order to adjust possible interventions more in line with their reality. The motives and expectancies of this pattern of consumption, as well as the consequences derived from it, are some of the variables that are shown to have the greatest weight in the prediction of BD. In the present study we analyze, on the one hand, the performance of these variables among college women with alcohol use, and on the other hand, which of these variables allow us to classify BD. A total of 501 female university consumers of alcohol (mean age 19.02 years) were assessed. Specifically, they completed a self-report of alcohol consumption (77.1% engage in BD), the Expectancy Questionnaire (EQ), the Drinking Motives Questionnaire (DMQ-R) and the Alcohol Consumption Consequences Evaluation (ACCE). BD female students scored significantly higher on these instruments, except for compliance motives. The logistic regression analysis carried out to estimate the probability of performing BD using the social and conformity motives, the ACCE and positive expectancies correctly estimated (χ2 8 = 9.149, p < 0.33) 88.6% of the cases and explained 26.2% of the BD. Thus, young women with a level of consequences classified as high risk (>25 in ACCE) have a 3.55-fold increase in the probability of having BD, compared to women classified as low risk by the ACCE. On the other hand, women classified as moderate risk by the ACCE have a 4.77-fold increase in the probability of having BD. In the case of social motives and positive expectancies, their increase multiplies by 1.165 and 1.024, respectively, the probability of having BD. The results of this study highlight the importance of adapting preventive measures to the consequences experienced by BD university students, especially in relation to the social motives and positive expectancies that modulate decision-making when engaging in this pattern of consumption.

Positive alcohol expectancy and resting-state functional connectivity of the insula in problem drinking

Positive alcohol expectancy (AE), a significant predictor of excessive alcohol consumption, is associated with heightened drinking motivation and reduced control. As the insula interacts with the limbic and prefrontal structures to integrate stimulus saliency, interoception, and cognitive control, the region may play a unique role in modulating AE. Here, we examined resting-state functional connectivity of the right and left insula in relation to AE in 180 adult drinkers. Whole-brain multiple regressions and path analysis were performed to delineate the inter-relationship between AE, insular connectivity, and drinking severity. We found that heightened AE was associated with diminished right insular connectivity with regions involved in negative emotion processing and self-control, including the amygdala, putamen, and ventromedial prefrontal cortex. In contrast, there was a positive relationship between AE and right insular connectivity with regions implicated in motivated responses to alcohol stimuli, including the superior parietal lobule, postcentral and superior frontal gyri. Path analysis showed that the two sets of right insular connectivity exhibited opposing associations with AE and that their net strength (i.e., "control minus motivation") was negatively correlated with AE and drinking severity. Analyses of the left insula seed, in contrast, did not yield regional connectivity in significant correlation with AE. These findings highlight the roles of right insula connectivity in motivational and regulatory processes that may differentially modulate drinking behavior. Recruitment of the motivational circuit and/or disengagement of the affective control circuit would be associated with heightened AE and heavier alcohol consumption.

Discussion of alcohol consequences during a brief motivational intervention session: Comparing those who do and do not increase readiness to change

The present study was designed to take an inductive, qualitative approach to understanding how discussion of alcohol-related consequences during brief motivational interventions (BMI) relate to readiness to change (RTC) prior to versus at the end of a session. Participants were thirty-four adults (35% female) recruited from the emergency room and enrolled in a randomized clinical trial of a BMI for risky alcohol use and risky sex. Seventeen participants both began and remained low on RTC over the course of the session. We selected 17 additional participants, matched on demographics, but who increased RTC over the session. Transcripts were qualitatively coded and analyzed separately within groups. Among participants who increased their RTC relative to participants who remained low on RTC by BMI end, evaluation of alcohol consequences as negative was more typical. In both groups, several consequences were neutrally evaluated. Many who remained low on RTC attributed consequences to something other than alcohol and/or minimized consequence severity. Study findings highlight the value for clinicians in eliciting and maximizing the importance of subjectively negative recent consequences to perhaps increase heavy drinkers' readiness to decrease heavy alcohol use.

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.

Do Alcohol Consequences Serve as Teachable Moments? A Test of Between- and Within-Person Reciprocal Effects From College Age to Adulthood

OBJECTIVE

Several studies find between-person reciprocal relations between adolescent/college drinking and positive expectancies. However, drinking and expectancies from college into adulthood are largely unstudied, as are within-person associations. During these age periods, negative alcohol consequences may represent "teachable moments" via expectancy change. The current study tested the reciprocal effects of drinking, negative consequences, and expectancies from college age to adulthood.

METHOD

Using data from a longitudinal study focused on familial alcohol disorder, age bands were created to model effects from college age (18-22) to young adulthood (23-28) and adulthood (29-34). Participants (N = 420) reported on their drinking, negative consequences, and expectancies across three waves (1995-2010).

RESULTS

Negative consequences did not predict negative expectancies, but the random intercepts of the two were highly related. Young adult negative consequences predicted a within-person increase in adult heavy drinking. A within-person increase in college age negative expectancies indirectly predicted a within-person decrease in adult negative consequences through reduced young adult drinking, whereas within-person increases in college age positive expectancies indirectly predicted a within-person increase in adult negative consequences through heavier young adult drinking.

CONCLUSIONS

Findings suggest that negative consequences were related to trait-level negative expectancies, even though prospective effects were not observed. Findings also suggest that college age negative expectancies were protective against future use and consequences, and this effect was unique to college age.

Qualitative examination of simultaneous alcohol and cannabis use reasons, evaluations, and patterns among heavy drinking young adults

Use of alcohol and cannabis together so their effects overlap (simultaneous use) is common among college students and associated with numerous negative consequences. The aim of this study was to gain insight into college students' recent simultaneous use events in order to inform future studies (i.e., generate hypotheses, inform measures/assessments of simultaneous use, and identify factors influencing simultaneous use). Qualitative interviews of simultaneous use experiences among heavy drinking college students (n = 38) were conducted to better understand reasons for simultaneous use, evaluations of simultaneous use events, and patterns of substance use during simultaneous use events. Findings indicated that students' reasons for simultaneous use included traditional four-factor motive types (i.e., social, conformity, enhancement, and coping), cross-fading motives, harm reduction motives (e.g., to drink less), and reactive/situational reasons (e.g., because it was offered/available). There was variability in participants' subjective evaluations of how positive versus negative simultaneous use events were and how this compared to single-substance events. Evaluation of simultaneous use events depended on patterns of use, external and internal context, and consequences experienced. Additionally, patterns of simultaneous use including order of substances, timing of using each substance, and quantities of substances used were highly variable across participants. Notably, participants endorsed patterns of use they perceived to reduce negative consequences during simultaneous use events. Further research on reasons for simultaneous use and patterns of use may help identify simultaneous use occasions that result in greater risk; identification of high-risk simultaneous use occasions and evaluation of these occasions can then help inform targeted interventions.

Do alcohol-related consequences and how they are evaluated predict consumption during and days until the next drinking event?

Objective: Alcohol-related consequences are most often examined as outcomes of alcohol use. However, it is also possible that experiencing consequences may predict future drinking behavior. The predictive power of consequences on future drinking behavior may involve both objective experiences of consequences and subjective evaluations of those consequences (i.e., how positive, how negative). The purpose of the present study was to understand how positive and negative alcohol-related consequences-and evaluations of those consequences-predict elements of the next drinking event among college students. Method: 96 participants reported alcohol use and related consequences over a 28-day daily assessment period. Results: Survival analysis and multilevel modeling were used to examine the influence of positive and negative consequences from a given drinking event on latency to and number of drinks consumed at the next drinking event. Contrary to hypotheses, subsequent drinking was not impacted by recent consequences nor how they were perceived. Conclusions: Though theoretically, experiencing alcohol consequences may impact proximal drinking behavior, findings suggest that, in the current sample, other factors have greater importance in the latency between drinking events and amount of alcohol consumed. Future work should continue to identify event-level predictors that impact behavior at the next drinking event, and ways drinkers attempt to avoid repetition of drinking consequences other than simply drinking less (e.g., protective behavioral strategies), as such factors would be valuable targets for intervention.

Opportunities for reducing college drinking: The roles of drinking attitudes and blackout experience

BACKGROUND

As many as 35% of college students report having been drunk in the past month, and greater alcohol use and alcohol-related problems are associated with a positive attitude toward heavy drinking. One serious consequence of heavy drinking is alcohol-induced blackout. When they occur, alcohol-induced blackouts present a unique opportunity to increase motivation to change drinking. However, it is unclear under what conditions an alcohol-related heavy drinking attitude and experiencing a blackout represent an opportunity to change and how experiencing a blackout(s) influences an individual's motivation to reduce drinking and actual behavior.

METHODS

This study tested the interplay between one's positive attitude toward heavy drinking and experiencing a blackout in the past year in predicting motivation to reduce drinking (Study 1) and its impact on drinking over time (Study 2). Data were derived from complementary datasets collected at two universities (Study 1 n = 703, mean age = 20.63 years, 44% male, 52% White; Study 2 n = 568, mean age = 19.18 years, 72% male, 84% White). Drinking behavior was measured using a modified Daily Drinking Questionnaire, the Drinking Norms Rating Form, the Alcohol Use Disorders Identification Test (AUDIT), and estimated peak blood alcohol concentration (BAC). Regression analyses were conducted to determine whether a blackout would moderate the association between attitude and motivation to reduce drinking (Study 1) and drinking over time (Study 2).

RESULTS

Results revealed a significant interaction between attitude and blackout, such that individuals who experience a blackout (vs. those who do not) and positively evaluate heavy drinking evidenced lower motivation to reduce drinking (Study 1) and higher levels of estimated peak BAC (Study 2).

CONCLUSIONS

Drinkers with a negative attitude toward heavy drinking who have experienced a blackout have the strongest motivation to reduce drinking and the greatest reductions in peak drinking behavior over time. These effects are over and above that related to the level of alcohol consumed. For young adults who do not positively endorse heavy drinking, blackouts may present a "moment of opportunity" for intervention.

Intentions and motives to experience alcohol-induced blackout among young adults in college

Blackouts are typically considered a negative consequence of alcohol use. Yet some college students report consuming alcohol with the intention of blacking out. This study examined intentions and motives for blackout drinking among young adults in college. College students with a past-year history of blackout (N = 350, 56% female, 73% White) completed an anonymous online survey. Descriptive statistics were used to examine the incidence of blackout intentions, and individuals who did and did not report future blackout intentions were then compared on drinking patterns, depressive symptoms, social norms, and outcome expectancies. Overall, 135 participants (39%) reported consuming alcohol in the past 30 days with the intention of losing memory of the night's events, and 107 (31%) reported blackout intentions in the next 30 days. When asked (via open text box) to indicate their motives for past blackout intentions, the majority of participants provided responses that fit with coping, social, or enhancement drinking motives. A larger proportion of men than women reported blackout intentions. As a group, those reporting future blackout intentions reported heavier, more frequent, and more problematic drinking, as well as more symptoms of depression and more positive (but not negative) outcome expectancies. A substantial subset of college students reporting a blackout in the past year also endorsed intentions to experience a blackout in the next 30 days. Given strong associations between intentions and subsequent behavior, interventions targeting blackout styles of drinking are warranted. The extent to which "blackout" drinking motives differ from traditional drinking motives is unclear. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Trajectories of College Alcohol Involvement and Their Associations with Later Alcohol Use Disorder Symptoms

Little is known about what differentiates individuals whose drinking patterns escalate into problematic use following the transition out of college compared to those who learn to drink in a way that is consistent with independent adult roles. Patterns of alcohol use and problems during college may pre-sage progression toward problem drinking in adulthood. The present study sought to examine such patterns in an effort to delineate those at greatest risk. Research has not yet elucidated whether, when, and how these groups diverge. Our results indicate that students who report AUD symptoms one year following graduation reported greater alcohol involvement from the first semester and escalated their involvement with alcohol at a more rapid pace. We observed marked and measurable differences in drinking patterns between those who go on to exhibit AUD symptoms following college and those who do not. A close inspection of these differences reveals that relatively small absolute differences in alcohol consumption add up to large differences in alcohol-related consequences. Thus, markers of longer-term risk are present early in college, and greater escalation of drinking across college is an indicator that intervention is needed. Brief Motivational Interventions could help students to anticipate some of the challenges ahead as they transition from the college environment, as well as the potential deleterious effects of immoderate alcohol use on making a successful transition into adult roles. In addition to the beginning of college, our findings also point to critical periods during which screening and brief intervention may be optimally timed.

Does Cannabis Use Predict More Severe Types of Alcohol Consequences? Longitudinal Associations in a 3-Year Study of College Students

BACKGROUND

Prior research shows that negative drinking outcomes among young adults may be exacerbated by cannabis use. However, to date, there have been few longitudinal studies of associations between cannabis use and negative alcohol-related consequences. This study examined longitudinal within-person associations between cannabis use and several domains of negative alcohol consequences among young adults and explored the moderating role of sex.

METHOD

We analyzed data from N = 997 students assessed 4 times per year over the first 3 years of university. At each time point, participants completed measures of past-month cannabis use frequency, typical weekly number of drinks, and 8 domains of negative alcohol consequences. Longitudinal associations were examined in multilevel models.

RESULTS

Within-person changes in frequency of cannabis use were not uniquely associated with changes in total alcohol consequences aggregated across several alcohol consequence domains. However, when examining alcohol consequence domains separately, within-person increases in cannabis use frequency were specifically associated with increases in some (but not all) of the more severe types of alcohol consequences, including risky behaviors, poor self-care, and alcohol dependence symptoms. No support was observed for the moderating role of sex in the longitudinal within-person associations between cannabis use and alcohol consequence domains.

CONCLUSIONS

Findings suggest that within-person changes in cannabis use frequency among young adults are associated with corresponding changes in some domains of alcohol consequences (but not others) when examined over the course of several years. Results may inform targeted harm reduction interventions for young adult drinkers who use cannabis, although future research is needed to clarify the mechanisms of the observed associations.

Posting Post-Blackout: A Qualitative Examination of the Positive and Negative Valence of Tweets Posted after "Blackout" Drinking

Alcohol-induced memory loss (i.e., blackout) is a consequence of drinking that is both common and associated with additional negative outcomes. The goal of the present study was to use publicly available Twitter data to better understand cognitions and emotions following blackouts. Tweets containing key terms (e.g., "black out") were collected over 4 days in 2018. Using NVivo software, we coded all post-blackout Tweets for valence (positive, negative, neutral). Within each valence category, we reviewed Tweets to identify themes. Among Tweets coded with a positive valence, themes included pride in blacking out, pride in ability to function despite blackouts, blackouts as a shared social experience, and overall positive views of a drinking experience despite blackouts. Among Tweets coded with a negative valence, themes included the experience of other negative consequences on blackout nights, blackouts as unexpected/unplanned, blackouts as motivator of change, and blackout-related negative emotions. Additionally, Tweeters expressed pride in avoiding blackouts during drinking events. Findings provide insight into why not all individuals describe blackouts negatively, by analyzing specific statements made in a public forum following a blackout. Such insight may inform interventions targeting those who report this risky outcome of drinking, including those that could be delivered via social media.

A Test of the Theory of Planned Behavior in the Prediction of Alcohol-Induced Blackout Intention and Frequency

BACKGROUND

This study examined the theory of planned behavior (TPB) as an explanatory model for alcohol-induced blackouts among college students. Blackouts are periods of time wherein individuals continue to function and engage in their social environment but do not remember it as a result of consuming large quantities of alcohol. Social cognitive factors posited within TPB, such as perceived norms and personal attitudes toward alcohol consumption, are reliable predictors of alcohol use and related problems. However, research to date has not examined these theoretical antecedents as predictors of alcohol-induced blackout.

METHODS

College students with a history of blackout (N = 384) completed a baseline survey, and a subsample (N = 120) completed a 1-month follow-up survey. Negative binomial mediation models were used to evaluate intentions to blackout as a mediator of the norms, attitudes, and self-efficacy to avoid blackout-blackout frequency association at baseline and 1-month follow-up.

RESULTS

Norms, attitudes, and self-efficacy to avoid blackout all significantly predicted blackout intentions at baseline, which in turn predicted more frequent blackouts both at baseline and at 1-month follow-up. Notably, blackout attitudes demonstrated both direct and indirect associations with blackout frequency.

CONCLUSIONS

Prospective analyses provided partial support for the TPB, with only attitudes and intentions demonstrating prospective associations with actual blackout frequency. Given the particularly strong association between blackout attitudes and frequency of blackouts, attitudes may represent an important and novel target for prevention and intervention efforts.

Learning From Experience? The Influence of Positive and Negative Alcohol-Related Consequences on Next-Day Alcohol Expectancies and Use Among College Drinkers

OBJECTIVE

The purpose of the present study was to examine daily-level associations between alcohol-related consequences and next-day expectancies and alcohol use among frequently drinking college students using a measurement-burst daily diary study.

METHOD

College students (N = 327; mean age = 19.7 years, SD = 1.26; 53.4% female) participated in a yearlong study in which they completed computerized interviews daily via mobile phones for 2 weeks in each academic quarter. Multilevel modeling was used to examine whether positive and negative consequences were associated with next-day alcohol expectancies and alcohol consumption.

RESULTS

Experiencing positive consequences from drinking was significantly associated with higher positive expectancies and a greater number of drinks consumed on the following day. The within-person association between daily consequences and next-day positive expectancies was stronger for those who were in fraternities/sororities compared with those who were not. Negative consequences were significantly associated with higher negative expectancies the next day but were not associated with number of drinks consumed the next day.

CONCLUSIONS

Results of this study highlight the role of direct drinking experiences in influencing future expectations and drinking behavior using a method that enables analysis of both between- and within-person associations.

Are Co-users of Alcohol and Marijuana More Willing to Experience Consequences From Drinking? A Longitudinal Examination Among First-Year College Students

BACKGROUND

Alcohol and marijuana co-users are at heightened vulnerability for experiencing a variety of negative alcohol use outcomes including heavier alcohol use and driving under the influence. The current study explored willingness to experience negative consequences as a potential factor underlying the association between co-user status and negative consequences in an effort to guide future intervention work. From a longitudinal study of first-year college students, we examined willingness to experience consequences at Time 2 as a mediator of co-user status at Time 1 and experience of negative consequences at Time 3.

METHODS

First-year college student drinkers (n = 1,914) at a large university completed surveys in the fall and spring of their freshman year and the fall of their sophomore year.

RESULTS

Alcohol and marijuana co-users reported higher willingness to experience consequences than alcohol-only users. Willingness to experience consequences partially explained the association between alcohol and marijuana couse and consequences.

CONCLUSIONS

The current study was the first to compare co-users of alcohol and marijuana to alcohol-only users on willingness to experience consequences, and examine the role of willingness as a mediator between co-user status and consequences experienced. Co-users were more willing to experience adverse effects from drinking, in turn predicting more consequences. Intervention work targeting consequences may be less effective for co-users; thus, additional work is needed to identify other potential mechanisms for change for this at-risk group.

Revisiting the Drinker Inventory of Consequences: An extensive evaluation of psychometric properties in two alcohol clinical trials

Alcohol-related consequences are linked directly to the diagnostic criteria for alcohol use disorder (AUD). However, alcohol consumption outcome variables (e.g., percent days abstinent, heavy drinking days) remain the dominant outcome in AUD treatment research. Two reasons AUD treatment researchers have not shifted to include alcohol-related consequences as a primary outcome may be that previous studies have failed to provide convincing evidence of (1) the psychometric properties of measures of alcohol-related consequences, and (2) whether consequences measures are sensitive to change following treatment. The present study directly addresses these two concerns via psychometric evaluation and sensitivity/specificity testing of the Drinker Inventory of Consequences (DrInC; Miller, Tonigan, & Longabaugh, 1995) in two of the largest multisite clinical trials ever conducted (COMBINE Study, Anton, et al., 2006; and Project MATCH, Project MATCH Research Group, 1997). Results indicated that the five subscales commonly used for the DrInC had poor construct validity and were noninvariant across time. A newly developed three-factor model consisting of mild, moderate, and severe consequences had excellent psychometrics, including good internal consistency reliability, construct validity, and measurement invariance over time. The three-factor model of the DrInC was also sensitive and specific for detecting consumption outcomes in both COMBINE and MATCH and had convergent validity with measures of consumption and wellbeing. In conclusion, the three-factor DrInC may be a useful tool for defining AUD treatment success in a clinically meaningful way that aligns with diagnostic criteria. (PsycINFO Database Record

Advances in behavioral animal models of alcohol use disorder

Alcohol use disorder (AUD) is a multifaceted neuropsychiatric disease that combines behavioral, psychosocial, and neurobiological aspects. Over the previous decade, animal models have advanced in modeling the major psychological constructs that characterize AUD. These advances pave the road for more sophisticated behavioral models that capture addiction-related aspects, such as alcohol craving, compulsive seeking and intake, dependence, and relapse. In this review, we survey the recent progress in behavioral animal modeling of five aspects of AUD: alcohol consumption, dependence, and seeking; compulsivity in alcohol intake despite adverse outcomes; vulnerability and resilience factors in alcohol addiction; relapse despite treatment; and relapse prevention by manipulating alcohol-associated memory reconsolidation. These advances represent a general attempt to grasp the complexity and multidimensional nature of AUD, and to focus on behavioral characteristics that better reflect and model this disorder.

How do college students subjectively evaluate "blackouts"?

Blackouts (i.e., alcohol induced memory impairment) are common among college student drinkers, and they are associated with several additional harms. However, alcohol consequences are not perceived universally as negative by the students who experience them, and little is known regarding students' specific thoughts and feelings about blackouts. We conducted a series of single-gender focus groups (8 groups; 5-8 per group; n = 50, 56% female) with college student drinkers. Questions focused on: (a) their subjective evaluations of blackouts and (b) factors influencing those evaluations (i.e., what determines whether a blackout is perceived as a negative/neutral/positive experience). Verbatim transcripts were content analyzed using applied thematic analysis with NVivo software. Evaluations of blackouts were primarily negative, with some notable positive, neutral and mixed reactions. Influences on blackout evaluations included those demonstrated as influential on broader alcohol consequences in prior work (e.g., normative perceptions, social context). However, some contextual influences on evaluations that may be specific to blackouts included pre-blackout events, the objective severity (extent/length) of memory loss, what participants later learned had happened during the blackout, and whether or not they had expected to blackout. Findings provide insight into why some students are not necessarily concerned with blackout experiences.

Alcohol-Induced Amnesia and Personalized Drinking Feedback: Blackouts Predict Intervention Response

Alcohol-induced amnesia ("blackout") is a reliable predictor of alcohol-related harm. Given its association with other negative consequences, experience of alcohol-induced amnesia may serve as a teachable moment, after which individuals are more likely to respond to intervention. To test this hypothesis, alcohol-induced amnesia was evaluated as a moderator of brief intervention effect on (a) alcohol-related consequences and (b) the proposed intervention mediators, protective behavioral strategies and peak blood alcohol concentration (BAC). Baseline alcohol risk measured using the Alcohol Use Disorders Identification Test (AUDIT) was also evaluated as a moderator to rule out the possibility that amnesia is simply an indicator of more general alcohol risk. College students (N = 198) reporting alcohol use in a typical week completed assessments at baseline and 1-month follow-up as part of a larger intervention trial. Participants were randomized to assessment only (AO; n = 58) or personalized feedback intervention (PFI; n = 140). Hierarchical regression was used to examine direct and indirect intervention effects. A significant group-by-amnesia interaction revealed that only PFI participants who had experienced alcohol-induced amnesia in the past month reported decreases in alcohol consequences at 1-month follow-up. The PFI reduced alcohol-related consequences indirectly through changes in peak BAC, but only among those who had experienced amnesia at baseline. In contrast, baseline alcohol risk (AUDIT) did not moderate intervention effects, and use of protective behavioral strategies did not statistically mediate intervention effects. Findings suggest that loss of memory for drinking events is a unique determinant of young adult response to brief alcohol intervention. Normative feedback interventions may be particularly effective for individuals who have experienced alcohol-induced amnesia in the past 30 days.

Changes in implicit alcohol attitudes across adolescence, and associations with emerging alcohol use: Testing the reciprocal determinism hypothesis

Implicit alcohol-related cognitions develop during adolescence and are thought to play an important role in the etiology of adolescent alcohol use. Rooted in reciprocal determinism, a developmental theory of alcohol-related cognitions, the current study sought to enhance our understanding of the development of automatic alcohol associations and their relationship with alcohol use. To provide a theoretically aligned test of reciprocal determinism, we used latent change score models to examine whether growth in automatic alcohol associations and alcohol use was related to each other (between-person effects) and whether each construct led to changes in the other over time (within-person effects). Adolescents (N = 378) completed 4 annual assessments, spanning early to middle adolescence. Automatic alcohol associations were assessed with a Single Category Implicit Association Test, and we used a quadruple processing tree model to extract a more "process pure" index of these associations. Alcohol use increased from early to middle adolescence, as negative automatic alcohol associations weakened over that same time period. Although there was no support for between-person associations, on the within-person level, weak negative automatic alcohol associations at Waves 2 and 3 were associated with increases in drinking at subsequent waves. Alcohol use did not significantly predict changes in automatic alcohol associations. Findings suggest the utility of distinguishing within- and between-person associations to understand the development of automatic alcohol associations and that automatic alcohol associations are prospectively associated with alcohol use and a potential target for intervention, one that becomes an increasingly salient influence on drinking as adolescence progresses.

Distinctions in Alcohol-Induced Memory Impairment: A Mixed Methods Study of En Bloc Versus Fragmentary Blackouts

BACKGROUND

Blackouts-or memory loss for all or part of a drinking event-are reliable predictors of alcohol-related consequences. Studies suggest a distinction between en bloc (complete memory loss) and fragmentary (off-and-on memory loss) blackouts; however, research has not consistently differentiated between these 2 forms of blackout. This study aimed to validate the distinction between en bloc and fragmentary blackouts among young adults.

METHODS

Data were collected using qualitative (Study 1) and quantitative (Study 2) research methods. Participants in both studies were college students with a history of alcohol-induced memory impairment. They were recruited using community advertisement (Study 1, N = 50, 56% female) and Qualtrics survey panels (Study 2, N = 350, 56% female). Study 1 participants engaged in 8 focus groups. Discussions were audio-recorded, transcribed verbatim, and coded using applied thematic analysis. Findings guided assessment of en bloc and fragmentary blackout in Study 2. In Study 2, a separate sample of participants completed an online survey assessing drinking behavior, alcohol-induced memory impairment, and theoretical correlates of en bloc and fragmentary blackouts.

RESULTS

Study 1 participants differentiated between en bloc and fragmentary blackouts (which they referred to as "blackouts" and "brownouts," respectively) based on duration and extent of memory loss. They indicated that blackouts occur along a continuum, with en bloc "blackouts" at the extreme. They also stated that the term "blackout drinking" does not always imply memory loss. Study 2 participants reported higher rates of "brownouts" (81%) than "blackouts" (54%). They reported less negative outcome expectancies and attitudes, greater personal approval, higher prevalence estimates, lower self-efficacy, and stronger intentions for "brownouts" than "blackouts" (p < 0.001). Women perceived "blackouts/brownouts" as more prevalent than men and reported lower intentions to experience "blackouts" (p < 0.005).

CONCLUSIONS

Young adults are more permissive of fragmentary than en bloc blackout. En bloc blackouts may be a target for future interventions.

Positive excessive drinker prototypes predict greater drinking and alcohol problems

OBJECTIVES

According to the prototype willingness model, risky behaviours such as heavy drinking may be influenced by images of others who engage in this behaviour. In this study, we examined whether college students' prototypes of an individual who frequently drinks "over the limit" were associated with their own alcohol consumption and experience of alcohol-related problems during their first 2 years in college.

METHODS

We assessed students' (N = 340) prototypes of excessive drinkers and their own alcohol consumption and problems at four time points, across their first 2 years in college. Along with examining the trajectory of prototypes, consumption, and problems, we tested whether prototypes significantly predicted consumption and problems across the 2 years. Additional analyses examined whether the predictive value of prototypes was unique from related variables including perceived descriptive norms, perceived injunctive norms, and peer pressure to drink alcohol.

RESULTS

Primary analyses indicated that more positive prototypes of an excessive drinker were significantly associated with greater alcohol consumption in both year 1 and year 2. More positive prototypes were also significantly associated with experiencing more alcohol-related problems in year 2. These findings held when controlling for perceived descriptive and injunctive norms, and peer pressure.

CONCLUSIONS

Findings further support the importance of drinker prototypes to one's own drinking behaviour. By examining prototypes over time and their relationship to alcohol-related problems, this study makes a novel contribution to the existing research. Statement of contribution What is already known on this subject? Perceived norms (beliefs about how much others drink and what they approve of) are associated with own drinking. Individuals construct "risk prototypes," or images of people who engage in risky behaviours like drinking alcohol. Positive risk prototypes of drinkers have been associated with own willingness to drink and subsequent drinking. What does this study add? This study shows the trajectory of drinker prototypes across the first 2 years of college. Findings highlight consistent patterns of positive associations between drinker prototypes and own drinking. More positive drinker prototypes are associated with a greater number of problems with alcohol.

The influence of context in the subjective evaluation of "negative" alcohol-related consequences

College students may subjectively evaluate the consequences of drinking in unexpected ways, rating "negative" consequences as neutral or even positive experiences. We previously gathered qualitative evidence for several contextual factors that may influence one's subjective evaluations (e.g., social influences, intoxication level, concurrent positive consequences). The purpose of the present study was to quantitatively investigate whether student evaluations of consequences differ by various contextual factors. We administered an anonymous online survey to 214 college students (76% female, 69% drinkers, 48% heavy drinkers) in return for academic credit, on which they reported how positively or negatively they would evaluate 6 alcohol-related consequences (e.g., vomiting, being rude, blacking out) under different conditions. Paired samples t tests were used to compare evaluation ratings, averaged across consequences, under different hypothetical contextual conditions (e.g., among friends vs. strangers). Out of 16 contextual comparisons, all but one (first-time vs. repeated consequence) revealed significant differences in subjective evaluations; the pattern held in reduced samples of just drinkers or just heavy drinkers. Examples include that consequences were viewed more negatively (a) if occurring at either a party or bar versus alone in one's home/dorm, (b) if friends express concern versus find it funny, (c) if the consequence was expected versus unexpected, and (d) if there are lasting consequences versus none. When using recent consequences in feedback-based interventions to build motivation to change, it may be useful to discuss the context of a consequence and how this influences the perceived aversiveness of that consequence.

College alcohol beliefs and drinking consequences: A multiple mediation analysis of norms, expectancies, and willingness to experience drinking consequences

OBJECTIVE

We explored the potential mediating role of willingness to experience drinking consequences and other traditional alcohol outcome predictors (descriptive norms, injunctive norms, positive alcohol expectancies) in explaining the association between college alcohol beliefs ¹ (CABs) and the actual experience of drinking consequences among college students.

PARTICIPANTS

The sample consisted of 415 college students tested in October 2014.

METHODS

Participants responded to an online survey.

RESULTS

When compared to both types of norms and positive alcohol expectancies, CABs demonstrated the strongest associations to both willingness to experience drinking consequences and actual drinking consequences among college students. A multiple mediation analysis revealed that the impact of CABs on students' actual drinking consequences was mediated only through their willingness to experience drinking consequences.

CONCLUSIONS

Students' college alcohol beliefs and their corresponding willingness to experience drinking consequences should be targeted in prevention and intervention programs designed to address the problem of college student drinking.

Adolescents who experienced negative alcohol-related consequences are willing to experience these consequences again in the future

Alcohol use and risky single occasion drinking are common among adolescents and are associated with a higher risk of various negative social, physical, academic, or sexual consequences. Studies have shown that among college students, willingness to experience negative consequences is associated with a higher likelihood of experiencing these consequences in the future. However, it remains unclear how experiencing negative consequences influences adolescents' willingness to experience them again. Based on a representative sample of 1,333 alcohol-using 14- to 15-year-olds (47.9% female), a path model was used to examine the associations between risky drinking, negative social and physical consequences, and willingness to experience the specific consequence in the future. As hypothesized, more frequent risky drinking was positively associated with experiencing negative consequences (i.e., saying or doing embarrassing things, regretted sexual experiences, impairment of schoolwork, problems with parents/friends, accident or injury, hangover, vomiting, memory lapses). Contrary to our second hypothesis, adolescents who experienced a negative consequence were also consistently willing to experience it in the future. Findings suggest that adolescents may see the experience of negative consequences as a necessary evil to attain the positive consequences. Prevention efforts may benefit from focusing on ways of attaining positive consequences by promoting alternatives to engaging in risky drinking practices, as well as reducing negative consequences (e.g., by promoting protective behavioral strategies).

Characteristics of prospectively identified negative alcohol-related events among college students

BACKGROUND

Throughout the first two years of college, the majority of drinkers experience one or more alcohol-related consequences. Research that examines the characteristics surrounding negative consequences typically utilizes global retrospective survey methods. The objective of the current study was to apply an event-based methodology to describe the circumstances of a recent drinking episode that resulted in one or more alcohol-related consequences among first- and second-year college students.

METHODS

We used a prospective web-based survey method to identify participants (N=296) who had one or more alcohol-related consequences in the past week. Shortly after reporting the consequence(s), participants attended an in-person interview during which they described the circumstances that preceded and followed the consequence(s), including the use of alcohol and other substances, proximal contextual factors including peer drinking, the characteristics of the negative alcohol-related consequence(s), and the reaction of others to the event.

RESULTS

The majority of participants reported experiencing the event at either their own (32.4%) or a friend's (32.8%) residence, and 87.1% of participants were with peers when the event happened. Most (85.0%) of the sample indicated that their closest friend knew about their event.

CONCLUSION

The high peer involvement at all stages of the event suggest the potential for training college students to help each other avoid or prevent consequences.

Efficacy of the College Drinkers Check-Up for Student Drinkers Living Off Campus

OBJECTIVE

Students living in off-campus housing consume more alcohol and experience more alcohol-related consequences than those living on campus, yet prevention efforts have not targeted this high-risk group specifically. The present study evaluated the efficacy of a brief, computer-delivered, alcohol intervention (the College Drinkers Check-Up [CDCU]) in reducing alcohol use and related consequences in a sample of college students living off campus.

METHOD

Students who lived off campus and reported at least one heavy drinking episode (4+/5+ drinks for females/males in one occasion) in the past 30 days completed the CDCU or assessment only during the first month of the school year (n = 326; 61% female). Participants in both conditions completed follow-up assessments at 1, 3, and 6 months. We hypothesized that participants who completed the CDCU would report fewer drinks per week and heavy drinking episodes, lower peak drinking quantities, and fewer alcohol-related consequences than those in the control group.

RESULTS

Hierarchical linear modeling was used to examine changes in drinking outcomes across groups from baseline to 1-, 3-, and 6-month follow-ups. Significant effects of time indicated less drinking and fewer consequences at each follow-up relative to baseline. Compared with those in the control group, participants who received the CDCU reported significantly fewer heavy drinking episodes at 1 month, lower peak drinking quantities at 3 months, and fewer alcohol-related consequences at 1 and 3 months. Neither sex nor baseline drinking severity moderated intervention effects.

CONCLUSIONS

The brief, online CDCU reduces heavy drinking and alcohol consequences in the short term among atrisk college students living off campus.

A qualitative examination of contextual influences on negative alcohol consequence evaluations among young adult drinkers

Alcohol misuse and associated negative consequences experienced by college students persists as a public health concern. Quantitative studies demonstrate variability in subjective evaluations of consequences, and how positively or negatively consequences are evaluated is associated with drinking behavior. Lacking is a qualitative exploration of how drinkers evaluate consequences and what influences those evaluations. We conducted a series of single-gender focus groups (13 groups; 3-7 per group; n = 62, 48% female) with college student drinkers. Questions focused on: (a) types of negative and positive consequences experienced (b) personal perceptions of negative consequences and (c) factors influencing those perceptions. Verbatim transcripts were content analyzed using applied thematic analysis with NVivo software. Several negative consequences not included in current assessment tools emerged. Reactions to these "negative" consequences of alcohol misuse were not labeled as uniformly negative by participants. Contextual influences on reactions to consequences included: social factors (e.g., normative perceptions, social context, discussions with friends), level of intoxication, concurrent positive consequences, time, and alcohol as an excuse. Future research should focus on consequence measure development and examine interactions between contextual and individual influences on subjective consequence evaluations. (PsycINFO Database Record

Insomnia moderates the association between alcohol use and consequences among young adult veterans

OBJECTIVE

Symptoms of insomnia and heavy alcohol use tend to co-occur among military and veteran samples. The current study examined insomnia as a moderator of the association between alcohol use and related consequences among young adult veterans in an effort to extend and replicate findings observed in samples of civilian young adults.

METHOD

Young adult veterans (N=622; 83% male; age M=29.0, SD=3.4) reporting alcohol use in the past year completed measures of insomnia severity, alcohol use, and alcohol-related consequences as part of a larger intervention trial. Participants were classified as screening 'positive' (n=383, 62%) or 'negative' (n=239, 38%) for insomnia using the Insomnia Severity Index. Hierarchical regression was used to examine the interaction between drinking quantity and insomnia on alcohol-related consequences. Predictor and outcome variables were measured concurrently.

RESULTS

Both a greater number of drinks per week and a positive insomnia screen were associated with more alcohol-related consequences. Drinks per week and insomnia screen interacted to predict alcohol-related consequences, such that the effect of drinking on alcohol-related consequences was stronger in the context of a positive versus negative insomnia screen.

CONCLUSION

Drinking is associated with more alcohol-related consequences in the presence of clinically significant insomnia symptoms. These findings replicate those documented in civilian young adults and indicate that insomnia may be an appropriate target for alcohol prevention and intervention efforts among young adult veterans.

Associated factors of readiness to change in young adult risky drinkers

BACKGROUND

Readiness to change alcohol use has been associated with a number of predictors including emotional distress, drinking severity, and consequence severity, as well as with static demographic factors such as gender and race/ethnicity.

OBJECTIVE

To examine the relationships among these variables and readiness to change alcohol use in young adults.

METHODS

Structural equation modeling was used to test pathways of readiness to change in 1,256 young adult patients (78% male/22% female) ages 18-29 who were provided screening, brief intervention and referral to treatment (SBIRT) as part of a Substance Abuse and Mental Health Services Administration (SAMHSA) Treatment Capacity Expansion Project.

RESULTS

The strongest relationships were between emotional distress, drinking severity, and consequence severity with readiness to change. Results indicated that participants with more severe alcohol problems demonstrated higher levels of readiness to change alcohol use and therefore, may be more amenable to behavior change. Additionally, females, Hispanic/Latino, and Black non-Hispanic (Black) participants demonstrated higher levels of readiness to change when compared to other groups.

CONCLUSION

These results lend support to the concept that young adults are using alcohol to modulate their emotions. Furthermore, resultant severity of consequences from drinking may play an important role in their readiness to change risky drinking. This may be especially true for females, who reported greater emotional distress, and for Hispanic/Latinos and Blacks, who reported greater drinking severity with greater emotional distress. Caregivers may be better equipped to address young adult alcohol use with this added understanding.

Peer alcohol behavior moderates within-level associations between posttraumatic stress disorder symptoms and alcohol use in college students

Self-medication theory (SMT) posits that individuals exposed to trauma and resulting posttraumatic stress symptoms (PTSD) are at risk for heavy drinking and associated negative consequences. Close peer alcohol use is also a powerful predictor of alcohol involvement in college, particularly influencing those with greater negative affect. As individuals with PTSD may rely on peers for support, peer drinking behaviors are possibly putting them at further risk for greater alcohol use and resulting consequences. To test self-medication processes, the present study examined the relationship between weekday PTSD symptoms, weekend alcohol behavior, and the influence of both emotionally supportive peer and other friend drinking behavior by investigating: (a) whether weekday PTSD symptoms predicted subsequent weekend alcohol use and consequences; and (b) whether the relationship between weekday PTSD symptoms and weekend alcohol behavior was moderated by various drinking behaviors of one's peers. Trauma-exposed heavy-drinking college students (N = 128) completed a baseline assessment and 30 daily, Web-based assessments of alcohol use and related consequences, PTSD symptoms, and peer alcohol behavior. Results directly testing SMT were not supported. However, friend alcohol behavior moderated the relationship between weekday PTSD and weekend alcohol behavior. Findings highlight the importance of peer drinking as both a buffer and risk factor for problematic drinking and provide useful information for interventions aimed at high-risk drinkers.

Subjective evaluations of alcohol-related consequences among college students: Experience with consequences matters

OBJECTIVE

Research suggests college students rate some alcohol-related consequences less negatively than others, yet it is unclear how or when these differences in perception develop. The current study compared college students' subjective evaluations of alcohol-related consequences that they had and had not experienced in order to test the hypothesis that students become desensitized to the consequences they experience.

PARTICIPANTS

Participants were 269 undergraduate students enrolled at a large, public, Midwestern university.

METHODS

Participants completed measures of drinking behaviors, consequences experienced, and subjective evaluations of consequences via an online survey.

RESULTS

Participants rated the consequences they had personally experienced more positively than those they had not experienced. Similarly, individuals who reported experiencing consequences rated them as significantly more positive than those who had not experienced the same consequences.

CONCLUSIONS

Experience with consequences is associated with more positive evaluations of those consequences. Therefore, it may be important to consider individuals' experiences with, and evaluations of, alcohol-related consequences in college student drinking interventions.

Evaluations and Perceptions of Others' Evaluations of Negative Alcohol-Related Consequences Predict Negative Alcohol-Related Consequences Among College Drinkers

OBJECTIVE

A key assumption when assessing alcohol-related problems is that these problems are considered negative. A growing literature suggests that college drinkers do not perceive all measured consequences to be negative. Research has established the impact of others' beliefs on personal beliefs and behaviors. The purpose of this study was to assess the effect of perceptions of others' evaluations (POE) of consequences on one's own evaluations and subsequent experiences of consequences.

METHOD

A sample of 885 heavy drinking college students participated in a longitudinal study. Participants reported the number of alcoholic drinks consumed per week, experiences of alcohol-related problems, evaluations of those consequences, and perceptions of how typical university students evaluate those consequences. A moderated mediation of POE on negative alcohol-related consequences via evaluations of consequences at differing levels of alcohol consumption was conducted, with gender, baseline consequences, and intervention effects being controlled for.

RESULTS

Results indicated that POE had no direct effect on subsequent consequences. However, an indirect effect was found through evaluations of consequences, such that there was a positive association between both POE and evaluations of consequences, and evaluations of consequences and subsequent consequences. Average weekly drinking moderated the association between POE and evaluations of consequences, such that the association between POE and evaluations of consequences was stronger for those who drank more heavily.

CONCLUSIONS

Results are consistent with social cognition processes, such as pluralistic ignorance, and suggest that POE and evaluations of consequences should be considered in the construction of interventions targeting heavy-drinking college students.

The associations among prior drinking consequences, subjective evaluations, and subsequent alcohol outcomes

Although the many positive and negative psychosocial consequences of alcohol use are well documented, evidence of the association between prior drinking consequences and subsequent alcohol-related outcomes is mixed. Social learning theory highlights that cognitive appraisals of prior drinking consequences play a crucial intermediate role in the relation of prior drinking consequences with subsequent alcohol-related outcomes. This prospective study was designed to test the mediating effects of subjective evaluations (i.e., perceived valence and controllability) in the association of prior drinking consequences with change in binge drinking and drinking consequences over time. Participants were 171 college students (69% female, 74% White, M age = 18.95 years, SD = 1.35) who completed 2 online surveys, with an average interval of 68 days (SD = 10.22) between assessments. Path analyses of the data did not support mediational effects of perceived valence or controllability of prior drinking consequences on subsequent alcohol-related outcomes. Specifically, greater frequency of negative consequences was associated with lower perceived valence and controllability, and greater frequency of positive consequences was associated with lower perceived controllability of the experienced consequences. However, perceptions of valence and controllability were not in turn associated with subsequent binge drinking and drinking consequences. Instead, greater frequency of positive consequences was directly associated with greater subsequent frequency of binge drinking. Findings highlight the importance of prior positive consequences in the escalation of binge drinking over a short period of time, although this relation may not be accounted for by perceptions of valence and controllability of the prior drinking consequences. (PsycINFO Database Record

When do college students have less favorable views of drinking? Evaluations of alcohol experiences and positive and negative consequences

College students experience numerous positive and negative consequences from drinking alcohol, although the extent to which these consequences influence perceptions of their drinking experiences is poorly understood. A better understanding of the impact of experiencing specific consequences, and how they are evaluated, on college students' perceptions of the overall drinking experience and subsequent alcohol use is crucial for advancing intervention efforts. The current study used daily data to examine (a) whether experiencing specific consequences and (b) whether ratings of the most favorable and most aversive consequences predicted overall evaluations of the drinking experience and perceptions that drinking was worth it; and (c) whether overall evaluations and perceptions that drinking was worth it predicted next-day drinking. College student drinkers (N = 349, 53.3% female) completed daily reports on drinking, consequences, evaluations of consequences, and evaluations of the drinking experience during four 2-week periods across 1 year. Findings from generalized estimating equations demonstrated that experiencing any of the positive consequences predicted more favorable overall evaluations and perceptions that drinking was worth it, whereas the majority of the negative consequences predicted less favorable overall evaluations. Ratings of the most favorable positive consequence and the most aversive negative consequence were also associated with overall evaluations. Perceiving that drinking was more worth it was associated with an increased likelihood of next-day drinking. Current findings reinforce the need to address the experience of both positive and negative consequences in interventions, while simultaneously considering the extent to which students perceived the negative consequences as aversive.

Ambivalence: Prerequisite for success in motivational interviewing with adolescents?

BACKGROUND AND AIMS

The exploration and resolution of ambivalence play an essential role in motivational interviewing (MI) theory. However, most adolescent MI studies have not examined ambivalence as a contributor to behaviour change. This paper reviewed research findings on the role of ambivalence in the adolescent change process.

METHODS AND RESULTS

We undertook a narrative review of the published empirical and theoretical literature on ambivalence and mechanisms of change in MI for adolescents and found that current MI evaluations appear not to have access to reliable and valid measures of ambivalence in adolescence or neuroimaging methods to evaluate the mechanisms of treatment response.

CONCLUSIONS

Improved instrumentation is needed to assess adolescents' ambivalence in clinical and research settings. Innovative methodology, including neuroimaging, may help identify factors mediating relationships between adolescents' ambivalence and treatment response.

Dangerous Beliefs: College Alcohol Beliefs Are Associated With Increased Risk of Regretted Sexual Encounters

This study explored the relative impact of college alcohol beliefs (CABs; i.e., the extent to which the student views alcohol as part of the fabric of college life), descriptive norms, injunctive norms, positive alcohol expectancies, and sensation seeking on college students' (N = 415) risk for engaging in regretted sexual encounters (RSE). Overall, 12% of our sample reported having experienced RSE within the past 30 days. When pitted against the other traditional predictors of college student drinking and its consequences, such as positive alcohol expectancies, descriptive and injunctive norms, and sensation seeking, CABs emerged as the strongest correlate of RSE other than drinking itself, and explained significant additional variance in RSE beyond these other predictors. Mediation analyses revealed that CABs had a significant indirect effect on RSE through typical weekly drinking. This pattern of findings indicates that college alcohol beliefs are, from a public health perspective, dangerous beliefs, that warrant serious consideration in the development of new approaches to college student drinking and its consequences.

Latent growth classes of alcohol-related blackouts over the first 2 years of college

Alcohol-related blackouts are common among college student drinkers. The present study extends prior work by examining latent growth classes of blackouts and several predictors of class membership. Participants (N = 709 college drinkers) completed a baseline survey at college entry and biweekly online assessments throughout freshman and sophomore years. Results revealed 5 latent growth class trajectories, reflecting varying experiences of blackouts at the beginning of college and differential change in blackouts over time. The largest class represented a relatively low-risk group (low decrease; 47.3%) characterized by endorsement of no or very low likelihood of blackouts, and decreasing likelihood of blackouts over time. Another decreasing risk group (high decrease; 11.1%) initially reported a high proportion of blackouts and had the steepest decrease in blackout risk over time. A small percentage showed consistently high likelihood of blackouts over time (high stable; 4.1%). The remaining 2 groups were distinguished by relatively moderate (moderate stable; 14.9%) and lower (low stable; 22.6%) likelihood of blackouts, which remained stable over time. Comparisons between classes revealed that students with greater perceived peer drinking, perceived peer approval of drinking, and enhancement motives upon entry to college tended to be in higher risk groups with consistent experiences of blackouts over time, whereas blackout likelihood decreased over time for students with greater conformity motives. Findings suggest that precollege preventive interventions may be strengthened by considering not only factors related to current risk for blackouts and other alcohol-related consequences, but also those factors related to persistence of these behaviors over time.

Addressing Inconsistencies in the Social Norms Drinking Literature: Development of the Injunctive Norms Drinking and Abstaining Behaviors Questionnaire

BACKGROUND

Informed by inconsistent findings regarding the association between injunctive norms (IN) and drinking behaviors, the current study developed a new measure of IN, the Injunctive Norms Drinking and Abstaining Behaviors Questionnaire (IN-DABQ). This measure addressed several psychometric weaknesses of prior assessment of this construct, specifically, reliance on single-item measures, and assessment of a limited range of drinking behaviors. The new measure also assessed norms for reasons for abstaining from drinking as college students often have simultaneous motives to use and inhibit their drug use. A parallel measure of descriptive norms (DN), the Descriptive Norms Drinking and Abstaining Behaviors Questionnaire (DN-DABQ), was created to allow for a comparison of the relative predictive effects of descriptive and IN in relation to different drinking outcomes.

METHODS

A college sample (N = 254, female = 50.42%) was recruited using Amazon's Mechanical Turk. Participants completed an online survey assessing demographic characteristics, social norms for 3 referents, weekly alcohol use, and alcohol-related consequences.

RESULTS

Exploratory factor analyses indicated 2 factors for the DN-DABQ and 3 factors for the IN-DABQ. The IN Drinking Behaviors factor consistently predicted weekly consumption and alcohol-related consequences across 3 reference groups (typical college student at your school, friends, and closest friends).

CONCLUSIONS

These findings suggest that prior inconsistencies in the relationship between IN and drinking behaviors are likely a function of poor measurement of this construct. Implications for normative feedback interventions are discussed.

Hypothetical evaluations of positive and negative alcohol consequences in adolescents across various levels of drinking experience

Research supports the importance of the subjective evaluation of alcohol-related consequences, and theory suggests that these evaluations may depend on one's prior experience. The goal of the present study was to understand how adolescents subjectively evaluate the potential negative and positive consequences of drinking and to test the hypothesis that evaluations differ as a function of personal experience with alcohol use and consequences. Participants were 697 adolescents (55% female) who completed online surveys assessing lifetime drinking experience and hypothetical evaluations of 13 negative and 9 positive consequences. Never having consumed a full drink of alcohol (vs. having consumed a full drink, but not having negative consequences) was significantly associated with higher mean negative evaluations and lower mean positive evaluations. Those who had a full drink (vs. those who had not) rated close to half of the negative consequence items as significantly less bothersome, and all of the positive consequences as significantly more enjoyable. However, there was little evidence in this sample that evaluations differ between drinkers with and without experience with negative consequences. Overall, findings suggest that youth who have experience with simply consuming alcohol may place more value on the positive and less value on some of the negative consequences of drinking, which has the potential to impact decisions to continue to drink. Longitudinal research uncovering the direction of evaluation-experience effects and mechanisms other than consequence experience, are essential next steps. (PsycINFO Database Record

Drinking consequences and subsequent drinking in college students over 4 years

There is some evidence that college student drinkers may continue drinking in the face of adverse consequences. We examined 2 hypotheses: (a) that this seemingly pathological behavior is a phenomenon of university life, occurring with consistency throughout the entirety of college, and (b) that individuals accumulate these consequences over multiple semesters in college. A sample of 3,720 students from a large Midwestern university was asked to complete surveys the summer before college and every semester thereafter for 4 years. Results showed that certain drinking-related consequences (e.g., blackouts, regretted sexual experiences) consistently predicted continued frequent heavy drinking in the following semester, even after controlling for sex, race, age, and previous-semester frequent heavy drinking (range of odds ratio = 1.17 to 1.45 across semesters, p < .01). Such potent consequences may predict subsequent drinking for a number of possible reasons that may be examined and addressed as they would pertain to specific protective behavioral strategy-related and cognitive interventions. Furthermore, consequences were accumulated over multiple semesters by notable proportions of students. For example, 13.8% of students reported blacking out 5 time-points or more--describing a full half or more of their college careers. Experimental studies which aim to modify students' perceptions of norms associated with these consequences may aid in developing interventions to reduce the burden of harm to students. In the broader context, and given the prevalence of students' accumulation of consequences, future study might aim to determine how and in what ways these findings describe either pathological or normative processes.

Psychometric analysis and validity of the daily alcohol-related consequences and evaluations measure for young adults

College students experience a variety of effects resulting from alcohol use and evaluate their experiences on a continuum from negative to positive. Using daily reports collected via cell phone, we examined the psychometric properties of alcohol use consequences and evaluations of those consequences. Participants were 349 undergraduate students (mean age 19.7 [SD = 1.26], 53.4% female). Data were analyzed using a multilevel factor analysis framework, incorporating binary items (consequences) and normally distributed items (evaluations). Our model converged on 2 factors-positive and negative-with similar loadings between- and within-persons. Intraclass correlation coefficients for positive consequences and their evaluations ranged from .30 to .40, whereas values for negative consequences were more variable. Intraclass correlation coefficients for negative evaluations were higher, suggesting evaluations were more trait-like compared to experience of consequences which may be context dependent. Generalizability coefficients on the whole were good to excellent, suggesting highly reliable scales at both person-mean and daily-mean levels. However, likely due to binary scale and infrequency, the generalizability coefficients for negative consequences at the daily level was somewhat low. Convergent validity was demonstrated by (a) positive associations between baseline Rutgers Alcohol Problem Index and Alcohol Use Disorders Identification Test scores with latent factors for daily positive and negative consequences, and (b) positive associations between daily drinking and daily consequences and evaluations of consequences. Overall, this measure demonstrated good psychometric properties for use in studies examining daily and lagged relationships between alcohol use and related consequences. (PsycINFO Database Record

Is Readiness to Change Drinking Related to Reductions in Alcohol Use and Consequences? A Week-to-Week Analysis

OBJECTIVE

The literature on whether readiness to change (RTC) alcohol use translates into actual change among college students is both limited and mixed, despite the importance of understanding naturalistic change processes. Few studies have used fine-grained, prospective data to examine the link between RTC and subsequent drinking behavior, and alcohol consequences in particular. The present study involves tests of whether (a) intraindividual changes in RTC are negatively associated with alcohol use and alcohol-related consequences from week to week, (b) the effect of RTC on use and consequences is direct versus mediated by change in alcohol use, and (c) the association between RTC and drinking behavior is moderated by gender.

METHOD

Participants were 96 college student drinkers who completed a baseline survey and 10 weekly web-based assessments of RTC, alcohol use, and consequences.

RESULTS

Hierarchical linear models indicated that, as hypothesized, reporting greater RTC on a given week (relative to one's average level of RTC) was negatively associated with alcohol use (measured by either drinks per week or frequency of heavy episodic drinking) and alcohol consequences the following week. Changes in use fully mediated the relationship between RTC and consequences. The prospective association between RTC and both alcohol use and consequences did not differ by gender.

CONCLUSIONS

Findings suggest that higher RTC translates into short-term reductions in alcohol use and in turn alcohol consequences, and highlight important avenues for future research.
