Impulsivity and Problem Drinking in College: Examining the Mediating Role of Sex-Related Alcohol Expectancies and Alcohol Use at Sex

Background: Dispositional impulsivity has been consistently implicated as a risk factor for problem drinking among college students and research suggests that this relationship may be explained in part by alcohol expectancies. A subset of alcohol expectancies, sex-related alcohol expectancies, is particularly linked to problem drinking among college students. The acquired preparedness model of risk postulates that people with dispositional impulsivity develop stronger sex-related alcohol expectancies, are subsequently more likely to drink at problematic levels in sexual situations, and thus, engage in more problem drinking. Objectives: Using this model, the current study examined whether sex-related alcohol expectancies and alcohol use at sex mediated the relationship between impulsivity and problem drinking among college students. Methods: College students (N = 101) completed self-report measures of alcohol use, sex-related alcohol expectancies, and five dimensions of impulsivity: negative urgency, positive urgency, sensation seeking, lack of premeditation, and lack of perseverance. Results: Two facets of impulsivity—sensation seeking and lack of premeditation—provided unique contributions to problem drinking. Sex-related alcohol expectancies significantly mediated the effects of lack of premeditation and sensation seeking on problem drinking. In support of the acquired preparedness model, the relationship between the impulsivity traits and problem drinking was serially mediated by sex-related alcohol expectancies and alcohol use at sex. Conclusions: Results suggest that sensation seeking and lack of premeditation continue to be areas of intervention for problem drinking among college students, and implicate sex-related alcohol expectancies as an area of intervention for alcohol use at sex and problem drinking.     

Is gender relevant only for problem alcohol behaviors? An examination of correlates of alcohol use among college students

This study examined correlates of alcohol use: substance-use coping, drinking to "feel high," and depressive symptoms as related to drinking behaviors in males and females. A sample of 266 female and 140 male college students from a private and public college were surveyed. Males reported more frequent alcohol use, alcohol-related problems, binge drinking, substance-use coping, and drinking to "feel high." There were no gender differences in self-reported depressive symptoms. Alcohol-use frequency and binge drinking were both accounted for by substance-use coping and drinking to "feel high" among males and females. However, alcohol-related problems were accounted for by males' frequency of alcohol use and drinking to "feel high," whereas females' problems were accounted for by frequency of alcohol use and depressive symptoms. Findings indicate that motivation for drinking is a more robust correlate of alcohol-related problems among males, while depressive symptomatology is a more relevant correlate of alcohol-related problems among females.     

Gender and Direction of Effect of Alcohol Problems and Internalizing Symptoms in a Longitudinal Sample of College Students

Background: Alcohol problems and internalizing symptoms are consistently found to be associated but how they relate to each other is unclear. Objective: The present study aimed to address limitations in the literature of comorbidity of alcohol problems and internalizing symptoms by investigating the direction of effect between the phenotypes and possible gender differences in college students. Method: We utilized data from a large longitudinal study of college students from the United States (N = 2607). Three waves of questionnaire-based data were collected over the first two years of college (in 2011–2013). Cross-lagged models were applied to examine the possible direction of effect of internalizing symptoms and alcohol problems. Possible effects of gender were investigated using multigroup modeling. Results: There were significant correlations between alcohol problems and internalizing symptoms. A direction of effect was found between alcohol problems and internalizing symptoms but differed between genders. A unidirectional relationship varying with age was identified for males where alcohol problems initially predicted internalizing symptoms followed by internalizing symptoms predicting alcohol problems. For females, a unidirectional relationship existed wherein alcohol problems predicted internalizing symptoms. Conclusions/Importance: We conclude that the relationship between alcohol problems and internalizing symptoms is complex and differ between genders. In males, both phenotypes are predictive of each other, while in females the relationship is driven by alcohol problems. Importantly, our study examines a population-based sample, revealing that the observed relationships between alcohol problems and internalizing symptoms are not limited to individuals with clinically diagnosed mental health or substance use problems.     

Impulsivity, negative expectancies, and marijuana use: a test of the acquired preparedness model

According to the 'acquired preparedness model,' expectancies mediate the relationship between an impulsive personality style and alcohol use. The current study evaluated whether the model can also be applied to marijuana use. Estimated probabilities and subjective evaluations of personally expected marijuana effects, along with impulsivity and frequency of marijuana use, were assessed in 337 college undergraduates. Tests of mediation examining positive and negative marijuana expectancies showed negative expectancies to be a significant mediator for both males and females. That is, participants who were higher on impulsivity had fewer negative expectancies and in turn used more marijuana. This study provides evidence that the acquired preparedness model may help to explain marijuana use.     

The gender specific mediational pathways between parenting styles,neuroticism, pathological reasons for drinking,and alcohol-related problems in emerging adulthood

Mediational links between parenting styles, neuroticism, pathological reasons for drinking, alcohol use and alcohol-related problems were tested. A two-group SEM path model with 441 (216 female, 225 male) college students was examined. In general, pathological reasons for drinking mediated the impact of neuroticism on alcohol use and alcohol-related problems. A different pattern of relationships was found for each of the two genders. Perceptions of having an authoritarian father were positively linked to higher levels of neuroticism among males but this pattern was not found among females. For males, neuroticism mediated the impact of having an authoritarian father on pathological reasons for drinking with pathological reasons for drinking mediating the impact of neuroticism on alcohol-related problems. Perceptions of having a permissive father were linked to lower levels of neuroticism in females (but have been found as a consistent risk factor for other pathways to alcohol use elsewhere). Compared with other work in this area, these findings indicate parental influences regarding vulnerabilities for alcohol use may be specific to parent–child gender matches for some pathways and specific to one parent (irrespective of child gender) for other pathways.     

Does gender moderate associations among impulsivity and health-risk behaviors?

The present study explores the relations among gender, impulsivity and three health-risk behaviors relevant to young adults (tobacco use, alcohol problems and gambling problems) in a sample of 197 college-age individuals. We sought to determine whether impulsivity is associated with health-risk behaviors in the same ways for men and women. For tobacco use and gambling problems, men were at higher risk than women, and impulsivity was not significantly associated with higher risk. Higher levels of motor impulsivity in men accounted for a significant amount of the gender difference in risk for alcohol problems. That is, impulsivity as measured by the Barratt Impulsiveness Scale (version 11), mediated the association between gender and risk for alcohol problems. For impulsivity as measured by Stop Signal Reaction Time (i.e. response inhibition), gender moderated the association between impulsivity and alcohol problems. Specifically, lower levels of impulsivity were associated with greater risk for alcohol problems in both men and women, but the effect was stronger in men. We speculate that this seemingly paradoxical result might be the result of coping drinking to deal with negative affect associated with behavioral overcontrol. These findings suggest that prevention efforts might well focus on identifying individuals at high risk for alcohol problems, especially males, by assessing response inhibition.     

Alcohol problems in young adults transitioning from adolescence to adulthood: The association with race and gender

Race and gender may be important considerations for recognizing alcohol related problems in Black and White young adults. This study examined the prevalence and age of onset of individual alcohol problems and alcohol problem severity across race and gender subgroups from a longitudinal study of a community sample of adolescents followed into young adulthood (N=166; 23-29 yrs. old who were drinkers). All alcohol problems examined first occurred when subjects were in their late teens and early 20s. Drinking in hazardous situations, blackouts, and tolerance were the most common reported alcohol problems. In race and gender comparisons, more males than females experienced alcohol problems. Blacks generally had a later age of onset of alcohol problems. Multivariate regressions showed greater alcohol problem severity in males compared to females, but no significant differences between Blacks and Whites. Education, family environment and earlier alcohol use behaviors and expectancies were reliable predictors of alcohol problem severity in young adulthood. White males were at particular risk for experiencing more severe alcohol problems. Findings may inform the design of more targeted interventions for alcohol problems in different populations.     

Disinhibition and expectancy in risk for alcohol use: comparing black and white college samples.

OBJECTIVE: This study tested several predictions of the "acquired preparedness" model in both black and white samples of college students. The acquired preparedness model holds that trait disinhibition affects alcohol-related learning and, ultimately, alcohol use. This model maintains that the reward focus typical of disinhibited individuals increases the likelihood of forming overly positive expectancies about the effects of alcohol. Alcohol expectancy, then, acts as a mediator of the relationship of disinhibition and drinking behavior. METHOD: Participants (N = 479, 341 women) were 279 white and 200 black college students. Self-reported alcohol expectancy, disinhibition and drinking behavior were assessed. Covariance structure analysis was used to test hypotheses separately for each sample, controlling for socioeconomic status. RESULTS: Black participants scored significantly lower on disinhibition, expectancy and drinking. However, invariance testing indicated that the relationships between these variables were not different across groups. Results were consistent with the stated hypotheses in both samples--alcohol expectancy functioned as a mediator of the disinhibition-drinking relationship. Results did not differ across expectancy content. CONCLUSIONS: These results provide support for the validity of the acquired preparedness model. Despite mean differences in risk and drinking levels between black and white samples, psychosocial learning appears to mediate the influence of disinhibition on drinking for both groups.     

Differentiating between sensation seeking and impulsivity through their mediated relations with alcohol use and problems

Disinhibition is a strong correlate of alcohol use, yet limited alcohol research has examined the facets of this personality construct. Recent work suggests that sensation seeking and impulsivity show differential relations with alcohol outcomes, indicating unique mechanisms of risks associated with each of these dimensions of disinhibition. The goal of the study was to examine sensation seeking and impulsivity as unique predictors of alcohol use and problems, and to test a broad range of drinking motives as potential mediators of these relations. Self-reported data from college students (N=310) were utilized for the study. Results suggested that sensation seeking and impulsivity were associated with alcohol use and problems through different mediational pathways. There was some evidence for gender moderating these pathways. The findings indicate that alcohol prevention and intervention programs should be tailored to specifically target individuals elevated on impulsivity versus sensation seeking.     

Protective strategies: A mediator of risk associated with age of drinking onset

The goal of the current study was to determine if failure to develop/utilize alcohol-specific strategies to manage drinking behavior might serve as a mechanism through which early alcohol exposure leads to higher levels of later alcohol use and alcohol-related negative consequences, while taking into account impulsivity as an underlying risk factor for both of these outcomes. Data were collected between September and December of 2005 from a random sample of college students via an online survey. A total of 309 students provided complete data on all measure of interest. Separate regression analyses predicting typical weekly alcohol consumption and alcohol-related problems indicated that use of alcohol-specific protective strategies partially mediated the effect of age of first use on these outcomes. An earlier age of onset was associated with less frequent use of alcohol-specific protective strategies, which in turn was associated with drinking- and alcohol-related problems. Implications for tailoring alcohol prevention and intervention programs targeting adolescents are discussed.     

The role of personality variables in drinking game participation

Drinking games are prevalent among college student and associated with increased risk of experiencing negative alcohol-related consequences. Personality variables, and specifically impulsivity and sensation seeking, have been linked to increased alcohol consumption and related negative consequences, but research on the relationship between personality and drinking game participation is limited. The current study used path analysis to assess the impact of sensation seeking and impulsivity on frequency of drinking game participation and related consequences in a sample of undergraduate college students. Findings suggest that sensation seeking and impulsivity are positively associated with frequency of drinking game participation. Both impulsivity and sensation seeking had a direct effect on negative consequences associated with drinking games, and both had an indirect relationship when controlling for the frequency of drinking game participation. The results are largely consistent with previous studies in suggesting that impulsivity and sensation seeking play a role in predicting risky alcohol use and related negative consequences. Understanding the relationship between personality variables and negative drinking game consequences may better inform the treatment of hazardous drinking among college students.     

Family history of alcohol abuse associated with problematic drinking among college students

Studies examining family history of alcohol abuse among college students are not only conflicting, but have suffered various limitations. The current report investigates family history of alcohol abuse (FH+) and its relationship with alcohol expectancies, consumption, and consequences. In the current study, 3753 student participants (35% FH+), completed online assessments. Compared to FH− same-sex peers, FH+ males and FH+ females endorsed greater overall positive expectancies, consumed more drinks per week, and experienced more alcohol-related negative consequences. Further, FH+ females evaluated the negative effects of alcohol to be substantially worse than FH− females. An ANCOVA, controlling for age, GPA, race, and alcohol expectancies, resulted in family history main effects on both drinking and consequences. An interaction also emerged between gender and family history, such that FH+ males were especially vulnerable to high levels of alcohol consumption. Results reveal the scope of FH+ individuals in the college environment and the increased risk for these students, particularly male FH+ students, suggesting a need for researchers and college health personnel to focus attention and resources on this issue.     

Impulsivity and risk-taking as predictors of alcohol use patterns and alcohol related-problems

This study examined the predictive utility of self-report measures of impulsivity and risk-taking in alcohol use outcomes (i.e. quantity, frequency, binge frequency, and alcohol-related problems). Participants were 370 (265 women) college student drinkers between ages 18 and 25?years from a mid-size east coast university. Participants completed measures of impulsivity, risk-taking, alcohol use, and alcohol-related problems. Impulsivity and risk-taking contributed uniquely to approximately 12% in quantity, 4% in frequency, 12% in binge frequency, and 7% in alcohol-related problems, after controlling for age and gender. When controlling for risk-taking, impulsivity accounted for more incremental variance in alcohol use outcomes (9% in quantity, 4% in frequency, 6% in binge frequency, and 5% in problems). Regarding specific impulsivity subscales, motor impulsiveness was more predictive of alcohol use variables whereas attentional and non-planning impulsiveness were predictive of alcohol-related problems. Although the risk behaviors subscale predicted some drinking indices and problems, risk assessment was not associated with any alcohol use outcome. Overall, the findings provide support for the predictive utility of both impulsivity and risk-taking in accounting for variability in various alcohol use behaviors and alcohol-related problems; however, findings suggest that impulsivity may have a stronger and more consistent association with alcohol use patterns and problems. The inclusion of both constructs in theoretical frameworks may aid our conceptualization of the role disinhibition has in college drinking and provide information for intervening efforts aimed at reducing risky alcohol behaviors.     

Understanding the relationship between social anxiety and alcohol use in college students: A meta-analysis

Many college students use alcohol, and most of these students experience problems related to their use. Emerging research indicates that socially anxious students face heightened risk of experiencing alcohol-related problems, although the extant research on alcohol use and social anxiety in this population has yielded inconsistent findings. This meta-analysis was conducted to examine the relationship between social anxiety and alcohol variables in college students. A literature search was used to identify studies on college students that included measures of social anxiety and at least one of the alcohol variables of interest. All analyses were conducted using random effects models. We found that social anxiety was negatively correlated with alcohol use variables (e.g., typical quantity and typical frequency), but significantly positively correlated with alcohol-related problems, coping, conformity, and social motives for alcohol use, and positive and negative alcohol outcome expectancies. Several moderators of effect sizes were found to be significant, including methodological factors such as sample ascertainment approach. Given that social anxiety was negatively related to alcohol use but positively related to alcohol-related problems, research is needed to address why individuals high in social anxiety experience more problems as a result of their alcohol use. Avoidance of social situations among socially anxious students should also be taken into account when measuring alcohol use. The primary limitation of this study is the small number of studies available for inclusion in some of the analyses.     

Protective behavioral strategies mediate the effect of drinking motives on alcohol use among heavy drinking college students: gender and race differences

Objective

This study examined the extent to which protective behavioral strategies (PBS) mediated the influence of drinking motives on alcohol consumption, and if these hypothesized relationships were corroborated across subsamples of gender and race.

Method

Online surveys were completed by 1592 heavy drinking college undergraduates from two universities (49.9% male and 50.1% female; 76.9% Caucasian and 23.1% Asian). Independent samples t-tests compared males and females as well as Caucasians and Asians on measures of drinking motives, PBS use, and alcohol consumption, and structural equation models examined the mediating role of PBS.

Results

Consistent with predictions, t-tests revealed that males reported greater levels of consumption than females, but females reported greater use of PBS than males. Caucasians reported greater consumption levels, endorsed higher enhancement motives, and higher PBS related to serious harm reduction, but Asians endorsed higher coping and conformity motives, and PBS focused on stopping/limiting drinking. In multiple-sample SEM analyses, PBS were shown to largely mediate the relationship between motives and consumption in all demographic subsamples.

Conclusions

Findings indicate that PBS use leads to reductions in drinking despite pre-established drinking motives, hence pointing to the potential value of standalone PBS skills training interventions in lowering alcohol use among diverse groups of heavy drinking college students.     

Personality and alcohol use: the role of impulsivity

Research has shown that personality traits associated with impulsivity influence alcohol use during emerging adulthood, yet relatively few studies have examined how distinct facets of impulsivity are associated with alcohol use and abuse. We examine the influence of impulsivity traits on four patterns of alcohol use including frequency of alcohol use, alcohol-related problems, binge drinking, and alcohol use disorders (AUDs) in a community sample of young individuals (N = 190). In multivariate regression analyses that controlled for peer and parental alcohol use, psychological distress, and developmental correlates (i.e., college, marriage, employment) in emerging adulthood, we found that urgency and sensation seeking were consistently related to all four constructs of alcohol use. The present study suggests that distinct impulsivity traits may play different roles in escalation of alcohol use and development of AUDs during emerging adulthood.     

Impulsivity and alcohol-related risk among college students: Examining urgency,sensation seeking and the moderating influence of beliefs about alcohol's role in the college experience

The personality trait of impulsivity is predictive of heavy drinking and consequences among college students. The current study examined how impulsivity—measured via positive urgency, negative urgency, and sensation seeking—and a person's beliefs about the role alcohol plays in the college experience relate to drinking and consequences in a sample of 470 college students (mean age = 19 years, 61.3% female, 59.8% White). In support of the hypotheses, sensation seeking independently predicted greater drinking, and both positive urgency and negative urgency predicted greater experience of alcohol-related negative consequences after controlling for consumption level. Moreover, alcohol beliefs moderated the relationship between impulsivity types and alcohol outcomes. Among students high (versus low) in sensation seeking, strong beliefs about alcohol's role in college life were related to significantly greater drinking, and among students high (versus low) in negative urgency, endorsing strong beliefs about alcohol's role in college life were related to greater levels of alcohol-related negative consequences. Overall, findings inform college prevention efforts by highlighting the need to distinguish unique facets of impulsivity and examine how they intersect with students' beliefs about alcohol in college.     

Poor adjustment to college life mediates the relationship between drinking motives and alcohol consequences: a look at college adjustment, drinking motives, and drinking outcomes

The current study examined whether the relationship between drinking motives and alcohol-related outcomes was mediated by college adjustment. Participants (N=253) completed an online survey that assessed drinking motives, degree of both positive and negative college adjustment, typical weekly drinking, and past month negative alcohol-related consequences. Structural equation modeling examined negative alcohol consequences as a function of college adjustment, drinking motives, and weekly drinking behavior in college students. Negative college adjustment mediated the relationship between coping drinking motives and drinking consequences. Positive college adjustment was not related to alcohol consumption or consequences. Positive reinforcement drinking motives (i.e. social and enhancement) not only directly predicted consequences, but were partially mediated by weekly drinking and degree of negative college adjustment. Gender specific models revealed that males exhibited more variability in drinking and their positive reinforcement drinking motives were more strongly associated with weekly drinking. Uniquely for females, coping motives were directly and indirectly (via negative adjustment) related to consequences. These findings suggest that interventions which seek to decrease alcohol-related risk may wish to incorporate discussions about strategies for decreasing stress and increasing other factors associated with better college adjustment.
