RESUMO

BACKGROUND: Simultaneous alcohol and cannabis use is common, but observational studies examining negative consequences of simultaneous use have rarely considered dose-related interactions between alcohol and cannabis. This study examined interactions between quantities of cannabis and alcohol consumed in predicting negative consequences on simultaneous use days. METHODS: Young adults (N = 151; 64% female; 62% White) reporting recent simultaneous use and at least weekly alcohol and cannabis use completed 21 daily, smartphone-based surveys assessing previous day quantities of cannabis and alcohol used, types of cannabis used (flower, concentrates, edibles), and negative substance-related consequences. Multilevel models examined: (1) whether negative consequences differed within-person across simultaneous use days and single-substance use days; and (2) whether quantities of alcohol and cannabis consumed on simultaneous use days interacted, within-person, to predict negative consequences. We focused on quantities of cannabis flower (grams) in primary analyses and explored quantities of other forms of cannabis (concentrates, edibles) in supplementary analyses. RESULTS: Participants reported fewer negative consequences on alcohol-only (243 observations) and cannabis-only (713 observations) days than they did on simultaneous use days (429 observations). On simultaneous use days involving cannabis flower use (313 observations across 81 participants), the within-person association between number of standard drinks and negative consequences was weaker on days during which larger (vs. smaller) amounts of cannabis flower were consumed. Inspection of simple slopes revealed that decreased alcohol use was associated with less of a decline in negative consequences when combined with relatively greater amounts of cannabis flower. CONCLUSIONS: Although simultaneous use was associated with more negative consequences than alcohol-only and cannabis-only use, negative consequences on simultaneous use days varied as a function of the interaction between alcohol and cannabis quantities. As findings suggest that using larger amounts of cannabis may attenuate declines in negative consequences associated with lighter drinking, interventions for higher-risk simultaneous use patterns may benefit from a focus on quantities of both alcohol and cannabis.

RESUMO

OBJECTIVE: Undergraduates frequently engage in risky drinking (i.e., drinking alcohol in ways that may result in problems). The reasoned action approach identifies injunctive norms (i.e., perceptions that others approve of risky drinking) as central in predicting engagement in risky drinking. However, research linking injunctive norms and risky drinking is equivocal, possibly because of extensive variability in the operationalization of injunctive norms across studies. This study describes the development and validation of the Perceived Approval of Risky Drinking Inventory (PARDI), designed according to best practice guidelines in questionnaire development. METHOD: Undergraduate students (N = 1,313) participated in one of the three phases of data collection, including focus group interviews for item generation (n = 31), self-report questionnaires for scale refinement (n = 407), and self-report questionnaires for scale validation (n = 875). RESULTS: Exploratory and confirmatory factor analyses supported a 20-item four-factor solution (Heavy Drinking, Drinking-Related Problems, Coping-Related Drinking, and Sexual-Risk Taking) across the three assessed referent groups (friends, parents, and typical students), all of which present satisfactory estimates of scale score and composite reliability. The results also provided preliminary support for the convergent validity of scores obtained on the PARDI, as demonstrated through correlations with other measures of perceived norms, alcohol use, alcohol-related problems, and coping-motivated drinking. Finally, the results supported the generalizability of the PARDI factor structure by demonstrating its measurement invariance across gender and drinking status (i.e., alcohol use and problems). CONCLUSIONS: The PARDI represents a reliable, valid, yet nuanced measure of injunctive norms that can be used to support further theory development and intervention.

RESUMO

Negative affect (depression/anxiety) and alcohol use among Indigenous youth in Canada remain a concern for many communities. Disparate rates of these struggles are understood to be a potential outcome of colonization and subsequent intergenerational trauma experienced by individuals, families, and communities. Using a longitudinal design, we examined change in alcohol use and negative affect, and reciprocal associations, among a group of Indigenous adolescents. Indigenous youth (N = 117; 50% male; Mage=12.46-16.28; grades 6-10) from a remote First Nation in northern Quebec completed annual self-reported assessments on negative affect (depression/anxiety) and alcohol use. A Latent Curve Model with Structured Residuals (LCM-SR) was used to distinguish between- and within-person associations of negative affect and alcohol use. Growth models did not support change in depression/anxiety, but reports of drinking increased linearly. At the between-person level, girls reported higher initial levels of depression/anxiety and drinking; depression/anxiety were not associated with drinking. At the within-person level, drinking prospectively predicted increases in depression/anxiety but depression/anxiety did not prospectively predict drinking. When Indigenous adolescents reported drinking more alcohol than usual at one wave of assessment, they reported higher levels of negative affect than expected (given their average levels of depression/anxiety) at the following assessment. Our findings suggest that when Indigenous youth present for treatment reporting alcohol use, they should also be screened for negative affect (depression/anxiety). Conversely, if an Indigenous adolescent presents for treatment reporting negative affect, they should also be screened for alcohol use.

RESUMO

Heavy drinking and smoking have been found to be among the leading causes of morbidity and mortality within Indigenous youth in North America. The focus of this study was to examine the relative roles of cultural identity, parent-child communication about the harms of substance use (SU), and perception about peers' opinions on heavy drinking and cigarette smoking among Indigenous youth. Strong Indigenous cultural identity, parent-child communication about SU, and affiliation with peers who do not use and/or who disapprove of substance use were all expected to reduce risk for heavy drinking and smoking. Substance use beliefs were hypothesized to mediate these effects. Youth (N = 117; Mage = 14.07; grades 6-11) from two Indigenous communities in Quebec completed self-reports. Consistent with the hypotheses, strong cultural identity predicted increased negative beliefs about substance use, which predicted reduced drinking and smoking. Similarly, affiliating with peers who did not use alcohol predicted decreased positive beliefs about alcohol use, which predicted reduced drinking. Affiliating with peers who did not smoke cigarettes predicted reduced cigarette smoking. Parental influences were not supported in this model. Intervention strategies may benefit from targeting cultural identity, peer groups, and substance use beliefs among Indigenous youth.

RESUMO

Background: Gray's original Reinforcement Sensitivity Theory (RST) posits that an oversensitive behavioral inhibition system (BIS) may increase risk for negative-reinforcement-motivated drinking, given its role in anxiety. However, existing data provides mixed support for the BIS-alcohol use association. The inconsistent evidence is not surprising, as the revised RST predicts that the behavioral approach system (BAS) should moderate the effect of the BIS on alcohol use. A strong BAS is thought to bring attention to the negatively reinforcing effects of alcohol, leading to problem drinking among those with a strong BIS. While emerging results support this interaction, we still have much to learn about the mechanisms underlying this effect on alcohol use. Accordingly, we examined motives for alcohol use as mediators of the joint associations of the BIS and the BAS on drinking behaviors. Specifically, our central hypothesis was that individuals with a strong BIS and a strong BAS would endorse increased negative reinforcement motives for drinking (coping and conformity motives), which in turn would predict heavy drinking and alcohol problems. Method: Participants (N=346; 195 women) completed study measures as part of the baseline assessment for a larger study. Results: Overall, results partially supported the hypotheses. Mediated moderation analyses showed that the indirect effect of the BIS on alcohol problems, through coping and conformity motives, was strongest at high levels of the BAS. This effect was not supported for alcohol use. Conclusions: Our findings suggest that clinical interventions should target coping and conformity reasons for drinking among anxious, reward responsive, young adults.

RESUMO

OBJECTIVE: Alcohol use and related problems increase during adolescence and peak in early adulthood. Tension reduction theories suggest that those high in anxiety sensitivity (AS) may be at risk for misusing alcohol for its anxiolytic effects. Cognitive theories point to drinking motives and alcohol expectancies as explanatory mechanisms of this risk pathway. This study examined AS risk for prospective alcohol misuse, as explained by an unfolding cognitive process, among those transitioning out of Collège d'enseignement général et professionnel (CEGEP, i.e., junior college equivalent in Quebec, Canada). We hypothesized that there would be trait-like (average levels over time), positive associations between AS, coping motives, tension-reduction alcohol expectancies, and alcohol use and problems, and that AS would lead to state-like (occasion-specific, reciprocal associations) bidirectional and positive associations between alcohol cognitions and outcomes. METHOD: Final-year CEGEP students (N = 193) completed three online questionnaires at 6-month intervals assessing AS, drinking motives (coping, enhancement), alcohol expectancies (tension reduction, sociability/liquid courage), and alcohol use/problems. State-trait modeling was used for hypothesis testing. RESULTS: Consistent with hypotheses, at the "trait" level, drinking motives and alcohol expectancies were positively associated, and drinking motives and sociability/liquid courage expectancies were positively associated with alcohol problems. At the "state" level, AS positively predicted coping motives and alcohol use, tension-reduction expectancies positively predicted coping motives, and coping motives and sociability/liquid courage expectancies positively predicted alcohol use. CONCLUSIONS: Results suggest that AS is a risk factor for coping-motivated drinking, and that there is interplay between cognitions that may help understand emerging adult alcohol risk pathways.

RESUMO

The association between restrained eating and alcohol use remains poorly understood among undergraduates. Consistent with tension reduction theory, individuals with disordered eating may be motivated to drink alcohol to cope with negative emotionality. Perhaps what pushes them to drink despite restriction goals is impulsivity. The combined impact of drinking to cope and impulsivity on the theoretically complex link between restrained eating and alcohol outcomes has not been previously examined. The current study tested the moderating effect of drinking to cope and impulsivity on the association between restrained eating and alcohol use and problems. Undergraduates (N = 1,619) self-reported on eating disorder symptoms, alcohol use motives, impulsivity, and alcohol outcomes. A moderation model revealed that restrained eating predicted past 30-day alcohol use, but only for women high in both drinking to cope and impulsivity. These findings help characterize alcohol misuse risk among young adults who restrict their eating, thereby, results may inform interventions.

RESUMO

Since the onset of the COVID-19 pandemic, researchers around the world have made efforts to assess its impact on youth mental health; however, the breadth of this topic has impeded a clear assessment of pandemic outcomes. This study aimed to address this gap by reviewing changes in youth (age ≤ 25) mental health, psychological wellbeing, substance use, and the use or delivery of relevant services during the pandemic. PubMed and Embase were searched in May 2021 to conduct a rapid review of the literature. The results encompass 156 primary publications and are reported using a narrative synthesis. Studies of mental health (n = 122) and psychological wellbeing (n = 28) generally indicated poor outcomes in many settings. Publications regarding substance use (n = 41) noted overall declines or unchanged patterns. Studies of service delivery (n = 12) indicated a generally positive reception for helplines and telehealth, although some youth experienced difficulties accessing services. The findings indicate negative impacts of the pandemic on youth mental health, with mixed results for substance use. Services must support marginalized youth who lack access to telehealth.

RESUMO

Many young adults struggle with comorbid alcohol misuse and emotional problems (i.e., depression and anxiety). However, there is currently a paucity of evidence-based, integrated, accessible treatment options for individuals with these comorbidities. The main goal of this study was to examine efficacy of a novel online, minimally guided, integrated program for comorbid alcohol misuse and emotional problems in young adults. Method: The study was an open-label two-arm RCT. Participants (N = 222, M age = 24.6, 67.6% female) were randomized to one of two conditions: the Take Care of Me program (an 8-week, online integrated treatment condition consisting of 12 modules), or an online psychoeducational control condition. Intervention modules incorporated content based on principles of cognitive behavioral therapy and motivational interviewing. Participants completed assessment data at baseline, at the end of treatment (i.e., 8 weeks), and at follow-up (i.e., 24 weeks). Data were analyzed using generalized linear mixed models. Results: We observed that participants in the treatment condition showed larger reductions in depression, hazardous drinking, as well as increases in psychological quality of life and confidence at the end of treatment. We did not find group differences on total alcohol use at follow-up, but participants in the treatment group reduced their hazardous drinking and improved their quality of life at 24-week follow-up. Conclusions: Our study provides promising initial evidence for the first iteration of the comorbid alcohol misuse and emotional problems online program.

RESUMO

OBJECTIVE: Trait negative urgency is consistently associated with alcohol problems, and cross-sectional findings have suggested a mediational role of impaired control over alcohol. Initial evidence also suggests that individual differences in self-reported sensitivity to alcohol's effects may moderate the association between urgency and alcohol outcomes. The aim of this study was to replicate and extend these findings using prospective data. METHOD: Young adult drinkers (N = 159, mean age = 18.87, SD = 1.16; 70.4% female) from Montreal, Quebec, Canada, completed an online survey at baseline and again 6 months later. Participants completed questionnaires measuring negative urgency, alcohol sensitivity, impaired control over alcohol, and hazardous drinking. RESULTS: Moderated mediation analyses revealed that the prospective indirect association between negative urgency at baseline and hazardous drinking at follow-up (mediated via increased impaired control at follow-up) was significant only for young adults who reported relatively lower alcohol sensitivity at baseline. CONCLUSIONS: Using prospective data from a unique sample of young adults, the present study partially replicates prior cross-sectional findings suggesting that the indirect association between urgency and hazardous drinking via impaired control over alcohol is moderated by alcohol sensitivity.

RESUMO

Many Indigenous communities are concerned with substance use (SU) problems and eager to advance effective solutions for their prevention and treatment. Yet these communities also are concerned about the perpetuation of colonizing, disorder-focused, stigmatizing approaches to mental health, and social narratives related to SU problems. Foundational principles of community psychology-ecological perspectives, empowerment, sociocultural competence, community inclusion and partnership, and reflective practice-provide useful frameworks for informing ethical community-based research pertaining to SU problems conducted with and by Indigenous communities. These principles are explored and extended for Indigenous community contexts through themes generated from seven collaborative studies focused on understanding, preventing, and treating SU problems. These studies are generated from research teams working with Indigenous communities across the United States and Canada-inclusive of urban, rural, and reservation/reserve populations as well as adult and youth participants. Shared themes indicate that Indigenous SU research reflects community psychology principles, as an outgrowth of research agendas and processes that are increasingly guided by Indigenous communities. At the same time, this research challenges these principles in important ways pertaining to Indigenous-settler relations and Indigenous-specific considerations. We discuss these challenges and recommend greater synergy between community psychology and Indigenous research.

RESUMO

Social anxiety (SA) is thought to relate to alcohol misuse. However, current evidence is inconsistent - especially in young adulthood. Recent non-experimental data show that trait impulsivity moderates the effect of SA on alcohol misuse. Specifically, this work suggests that concurrently elevated impulsivity may draw attention to the immediate, anxiolytic effects of drinking - thus promoting alcohol misuse among those high in SA. Otherwise, without elevated impulsivity, a socially anxious person may not drink due to focusing on alcohol's possible negative outcomes (e.g., embarrassing behaviours). The next step in this research is to examine if impulsivity impacts in-the-moment subjective craving among socially anxious individuals. This was the goal of the present experiment. After baseline measures, undergraduate participants (N = 110) completed the Trier Social Stress Test followed by an alcohol (versus neutral) cue exposure. Subjective craving ratings were collected at both baseline and post-cue exposure. Moderation analyses revealed that socially anxious individuals endorsed strong cravings following an alcohol (but not a neutral) cue exposure, but only if they also had elevated impulsivity. In-lab craving was positively correlated with retrospective reports of alcohol misuse. Our findings demonstrate that impulsivity contributes to SA-related risk for alcohol misuse.

RESUMO

BACKGROUND AND AIMS: Despite increases in female gambling, little research investigates female-specific factors affecting gambling behavior (GB). Although research suggests that some addictive behaviors may fluctuate across menstrual cycle phase (MCP), gambling requires further investigation. In two studies, we examined associations between MCP and three risky GBs: time spent gambling, money spent gambling, and the probability of consuming alcohol while gambling. Associations between MCP and negative affect were also examined in Study 2. We predicted that, consistent with self-medication theory, increases in negative affect (Study 2) and risky GBs (Studies 1 and 2) would occur premenstrually/menstrually relative to other phases. METHODS: Data were obtained from 33 female gamblers using a retrospective timeline followback procedure (Study 1) and from 20 female gamblers using a prospective 32-day, daily diary method (Study 2). In Study 2, salivary progesterone levels verified self-reported MCP validity. RESULTS: Findings revealed significant, but somewhat inconsistent, MCP effects on GBs across studies. The self-medication hypothesis was partially supported. Increases relative to another MCP(s) were found for alcohol consumption while gambling premenstrually, time spent gambling menstrually/premenstrually, money spent gambling menstrually, and negative affect premenstrually. Unexpectedly, findings more consistently indicated that GBs increased during ovulation, suggestive of enhanced reward sensitivity. Progesterone assays validated self-reported MCP (Study 2). DISCUSSION AND CONCLUSIONS: The results suggest a role of ovarian hormones on negative affect and GBs in females. This research could lead to the identification of female-specific factors affecting gambling and the development of more effective interventions for females with, or at risk for, problematic gambling.

RESUMO

BACKGROUND: Alcohol misuse and emotional problems (ie, depression and anxiety) are highly comorbid among Canadian young adults. However, there is a lack of integrated, accessible, and evidence-based treatment options for these young adults. OBJECTIVE: The main goal of this study is to develop and test the efficacy of an integrated, online self-help program designed to target both alcohol misuse and emotional problems. METHODS: A two-arm randomized controlled trial design will be used to compare the efficacy of the online integrated treatment to a psychoeducational control group. A target sample of 214 participants will be recruited and randomly assigned to either condition. The integrated treatment will last 8 weeks, and participants will work through 12 modules. Modules will incorporate content based on principles of cognitive behavioral therapy and motivational interviewing. Participants in the control group will receive links to psychoeducational resources and will have access to the full treatment after follow-up. The primary outcome will be the number of Canadian standard drinks consumed in the week leading up the assessment. Secondary outcomes of interest include symptoms of depression, anxiety, alcohol-related problems, quality of life, and use of other drugs. Assessments will be completed at 3 time-points: at baseline, at the end of treatment (ie, 8 weeks), and at follow-up (ie, 24 weeks). Upon completion, data will be analyzed using generalized linear mixed models. RESULTS: Data collection began in June 2018 and will continue until January 2020. Final study results will be submitted for publication by July 2020. CONCLUSIONS: Currently, there are no integrated treatments designed to target alcohol misuse and the range of emotional problems experienced by young adults. This research stands to provide an effective, accessible (ie, Web-based), and feasible option to treat the many struggling young adults in this country.

RESUMO

Depression and alcohol use disorders are highly comorbid. Typically, alcohol use peaks in emerging adulthood (e.g., during university), and many people also develop depression at this time. Self-medication theory predicts that depressed emerging adults drink to reduce negative emotions. While research shows that depression predicts alcohol use and related problems in undergraduates, far less is known about the continuity of this association after university. Most emerging adults "mature out" of heavy drinking; however, some do not and go on to develop an alcohol use disorder. Depressed emerging adults may continue to drink heavily to cope with the stressful (e.g., remaining unemployed) transition out of university. Accordingly, using parallel process latent class growth modelling, we aimed to distinguish high- from low-risk groups of individuals based on joint patterns of depression and alcohol misuse following university graduation. Participants (N = 123) completed self-reports at three-month intervals for the year post-graduation. Results supported four classes: class 1: low stable depression and low decreasing alcohol misuse (n = 52), class 2: moderate stable depression and moderate stable alcohol misuse (n = 35), class 3: high stable depression and low stable alcohol misuse (n = 29), and class 4: high stable depression and high stable alcohol misuse (n = 8). Our findings show that the co-development of depression and alcohol misuse after university is not uniform. Most emerging adults in our sample continued to struggle with significant depressive symptoms after university, though only two classes continued to drink at moderate (class 2) and high (class 4) risk levels.

RESUMO

Hazardous drinking in emerging adulthood is associated with multiple domains of alcohol problems, which range in type and severity. Alcohol problems at the severe end of the spectrum (e.g., impaired control) may be early warning signs of alcohol use disorders (AUDs) among emerging adults. However, given the emphasis in the literature on predictors of overall problem risk, we still know very little about predictors of these specific (and severe) domains of alcohol problems in emerging adults. Many emerging adults drink at social events (e.g., parties), but an estimated 15% engage in solitary drinking. Solitary drinking - a developmentally atypical behavior in emerging adulthood - may be especially risky. Data suggests that frequent solitary drinking may reflect a loss of control over drinking, leading to hazardous use and subsequent problems. Accordingly, we expected that frequent solitary drinking among emerging adults would predict severe alcohol problems that map onto diagnostic criteria for AUDs and these effects would be mediated by hazardous alcohol use. Undergraduates (N=118) completed self-report measures as a part of a larger study on motivation and alcohol use. As predicted, path analysis showed that solitary drinking positively predicted hazardous alcohol use, and this in turn predicted severe alcohol problems associated with diagnostic criteria for AUDs, particularly risky behaviors and blackout drinking. Solitary drinking also positively predicted less severe problems of diminished self-perception and poor self-care through hazardous use. Though comparatively smaller, some indirect effects were observed from social drinking (at parties, but not at bars) to alcohol problems, via hazardous alcohol use. Overall, our results suggest that solitary drinking is particularly harmful in emerging adulthood.

RESUMO

INTRODUCTION AND AIMS: This study tested the measurement invariance of the Drinking Motives Questionnaire-Revised Short Form (DMQ-R-SF) in undergraduates across 10 countries. We expected the four-factor structure to hold across countries, and for social motives to emerge as the most commonly endorsed motive, followed by enhancement, coping and conformity motives. We also compared individualistic and collectivistic countries to examine potential differences in the endorsement of drinking motives when countries were divided according to this broad cultural value. DESIGN AND METHODS: A sample of 8478 undergraduate drinkers from collectivistic (Portugal, Mexico, Brazil, Spain; n = 1567) and individualistic (Switzerland, Hungary, Canada, the Netherlands, the UK and Ireland, and the USA; n = 6911) countries completed the DMQ-R-SF. Countries were classified as individualistic or collectivistic based on world-wide norms. RESULTS: Using multigroup confirmatory factor analysis, the 4-factor model of the DMQ-R-SF showed configural and metric invariance across all 10 countries. As predicted, the rank order of undergraduates' drinking motive endorsement was identical across countries (social > enhancement > coping > conformity), although a mixed model analysis of variance revealed a significant interaction where undergraduates from individualistic countries more strongly endorsed social and enhancement motives relative to undergraduates from collectivistic countries. DISCUSSION AND CONCLUSIONS: There was broad cross-cultural consistency in the factor structure and mean patterns of drinking motives. Undergraduate students appear to drink mainly for positive reinforcement (i.e. for social and enhancement reasons), although this tendency is particularly pronounced among those from more individualistic countries.

RESUMO

The link between social anxiety (SA) and problematic drinking is complex; this seems predominantly true among young adults. Individuals high on SA are thought to be particularly sensitive to the negative effects of alcohol, which should deter them from drinking. Yet, some evidence suggests that those high on SA continue to drink despite experiencing negative alcohol-related consequences (NACs) (Morris, Stewart, & Ham, 2005). Although traditionally, researchers assume NACs are perceived as averse, emerging evidence suggests these are not categorically viewed as negative by undergraduates. The study goal was to test whether evaluations of NACs moderate the effect of SA on problematic drinking. It was hypothesized that high SA would predict elevated alcohol use and number of NACs experienced, but only for those who evaluate NACs as less negative. Undergraduate drinkers (N=130, 80 women) completed self-reports of social anxiety, NAC evaluations (ratings of how 'bad' experiencing each alcohol-related consequence would be), alcohol use, and NACs experienced. Regression analyses revealed that NAC evaluations moderated the effect of SA on number of NACs experienced, but not the effect of SA on weekly alcohol use. Simple slopes analyses showed that high SA was associated with elevated NACs experienced for those with weak negative NAC evaluations, controlling for alcohol use. These findings help explain the mixed SA-problematic drinking literature by identifying perceptions of NACs as an important moderator of SA risk for experiencing NACs. Moreover, clinical interventions aimed at reducing SA risk for undergraduate problematic drinking may benefit from targeting NAC evaluations.

RESUMO

BACKGROUND: There is great interest in the role of the behavioral inhibition system (BIS) and the behavioral approach system (BAS) in the etiology of alcohol use because of the strong links of these systems to neuroscience and cognitive models of addiction. The revised Reinforcement Sensitivity Theory suggests that the strength of the BIS and BAS jointly influences behavior, so-called the joint systems hypothesis. Yet, relatively little work has examined this hypothesis, particularly with respect to alcohol information processing. Grounded in dual-process theories of alcohol information processing, this study aimed to clarify the roles of implicit (i.e., automatic processes) and explicit (i.e., controlled processes) cognitions in BIS-related drinking. When anxious and presented with an alcohol (vs. neutral) cue, we expected those with an elevated BIS to have increased implicit and explicit alcohol cognitions related to tension reduction, but only at elevated BAS. Shifts in cognitions following cue exposure were expected to positively correlate with alcohol misuse. METHODS: Students (N = 110) completed baseline measures followed by the Trier Social Stress Test. This was followed by a cue exposure (random assignment to alcohol or water cue), during which participants completed postmood assessments of implicit/explicit alcohol cognitions. RESULTS: Overall, participants' implicit alcohol cognition was negative. The effect of BIS on implicit and explicit cognitions was moderated by BAS; however, results were not as hypothesized. In the alcohol condition only (when controlling for baseline implicit cognition), BIS predicted relatively weak implicit negative alcohol cognition, but only at low BAS. Interestingly, in the alcohol condition only, BIS predicted increased explicit reward (but not relief) expectancies, but only at high BAS. Changes in explicit reward expectancies positively correlated with alcohol misuse. CONCLUSIONS: Our results suggest that explicit cognitions may be relevant to drinking among anxious individuals who are also reward responsive. Cognitive behavioral interventions should target reward expectancies to reduce anxiety-related drinking.

RESUMO

BACKGROUND: Undergraduate students experience diverse problems because of alcohol use. Accordingly, the Young Adult Alcohol Consequences Questionnaire (YAACQ) was developed to assess multiple domains of alcohol-related problems. A preliminary psychometric evaluation in a U.S. college sample showed support for 8 factors that were invariant across gender and that loaded onto a single higher-order alcohol-related problems factor. Supporting concurrent validity, this preliminary work also found that YAACQ total scores correlated with heavy alcohol use. While these results are promising, the factor structure of the YAACQ has yet to be replicated. This goal of this study was to test the psychometrics of the YAACQ in a large Canadian student sample. Invariance across gender, year of study, place of residence, and relative drinking level was examined. Correlations between the YAACQ subscales and alcohol use measures were investigated to test concurrent validity. METHODS: Students (N = 1,103, 80% women) completed online self-reports. RESULTS: Results from a confirmatory factor analysis (CFA) supported an 8-factor lower-order structure, with all factors loading onto a single higher-order alcohol-related problems factor. Multigroup CFAs supported measurement invariance across gender, year of study, place of residence, and relative drinking level. YAACQ subscales were positively correlated with weekly alcohol use and binge drinking. CONCLUSIONS: Our study provides an important replication of the psychometrics of the YAACQ in a new sample, and we extend previous work by presenting novel tests of measurement invariance across meaningful groups in young adulthood. Overall, our study suggests that the 48-item YAACQ is a valid measure of alcohol-related problems in Canadian students.
