Impulsivity-related traits,college alcohol beliefs,and alcohol outcomes: Examination of a prospective multiple mediation model among college students in Spain,Argentina, and USA

ObjectivesThe present study examined (both cross-sectionally and prospectively) the mediational role of college alcohol beliefs in the relationship between impulsivity-related traits and alcohol outcomes (i.e., alcohol use and negative consequences) among college student drinkers from the United States (U.S.), Spain, and Argentina.MethodA sample of 1429 (U.S. = 733, Spain = 292, Argentina = 404) drinkers (at least one drinking episode within the previous month) completed the baseline survey, and 242 drinkers completed the follow-up. To test study aims, a cross-sectional model was first employed to examine whether the proposed double-mediated paths (i.e., each dimension of impulsivity → college alcohol beliefs → alcohol use → negative alcohol-related consequences) extends across samples with different cultural backgrounds (i.e., structural invariance testing). A longitudinal model was then conducted to assess if college alcohol beliefs prospectively mediate the associations between trait impulsivity and alcohol outcomes.ResultsCollege alcohol beliefs were concurrently and prospectively associated with both greater alcohol use and increased number of negative alcohol-related consequences. These internalized beliefs about college student drinking culture significantly mediated the effects of several distinct impulsivity-related traits on alcohol-related outcomes including urgency (positive and negative), sensation seeking, and perseverance. These findings were invariant across gender and across three countries (Argentina, Spain, and the U.S.).ConclusionsOur findings highlight the modulatory role of cognitive factors on problematic alcohol use among college students with different cultural backgrounds. Our results suggest that, despite the cultural differences exhibited by these three countries, the unique and mediational effects of college alcohol beliefs appear relatively universal.     

Depressive Symptoms and Drinking Outcomes: The Mediating Role of Drinking Motives and Protective Behavioral Strategies Among College Students

Background: College students with depressive symptoms tend to engage in more hazardous drinking and experience more alcohol-related consequences to cope with their symptoms. Given the perceived tension reducing effects of alcohol among these students, it is important to explore how protective factors, such as protective behavioral strategies, account for the relationships among depressive symptoms, drinking motives, and alcohol-related outcomes. Objective: To examine the mediating role of drinking motives and protective behavioral strategies on the associations that depressive symptoms have with typical weekly alcohol consumption, hazardous drinking, and alcohol-related negative consequences in a sample of college student drinkers. Methods: Traditional age college students (n = 566, 73% women; 58% White, non-Hispanic) completed measures of depression, drinking motives, protective behavioral strategies, weekly alcohol use, hazardous drinking, and alcohol-related negative consequences. Results: Coping with depression motives and controlled consumption PBS explained the association between depression and weekly alcohol consumption and hazardous drinking whereas coping with depression motives and serious harm reduction PBS explained the depression-negative consequences relationship. Conformity motives and serious harm reduction PBS explained the association between depression and hazardous drinking and alcohol-related negative consequences. Conclusions: Findings suggest that students with more depressive symptoms would benefit from clinical interventions tailored to address negative reinforcement drinking motives and, by extension, increase student utilization of PBS related to minimizing harm. Clinical and research implications are provided.     

Alcohol-related protective behavioral strategies as a mediator of the relationship between drinking motives and risky sexual behaviors

Risky sexual behaviors (RSB) frequently occur in the context of alcohol use and are associated with distinct drinking motives among college students. Use of alcohol protective behavioral strategies (PBS) is associated with reductions in alcohol use and related problems, which may extend to alcohol-related RSB. Moreover, as PBS use mediates the relationship between positive reinforcement drinking motives and alcohol-related problems, the same may be true for alcohol-related RSB, specifically. The current study examined whether PBS mediates the relationship between drinking motives and RSB among college students. Participants (N = 2039, 72.8% female, M_age = 19.79) from ten universities across ten U.S. states completed an online survey assessing past-month drinking motivation, alcohol PBS, alcohol consumption, and RSB. To test study aims, a saturated path model in which drinking motives were modeled as predictors of RSB via PBS use subscales and alcohol consumption was conducted. Several double mediation effects were found, such that stronger endorsement of motives (i.e., social, enhancement, conformity, coping for depression) were associated with lower PBS (particularly manner of drinking and serious harm reduction), which was associated with higher alcohol use, which was associated with higher RSB. Multi-group models found the mediation effects to be gender invariant, although several differences in direct associations were found across genders. For college students high in positive reinforcement motives (i.e., social or enhancement) for drinking, interventions that aim to increase PBS use, specifically related to modifying the manner in which one drinks and avoiding very dangerous consequences, may be effective in reducing alcohol-related RSB.     

Alcohol Expectancies Mediate the Relationship Between Age of First Intoxication and Drinking Outcomes in College Binge Drinkers

Background: While prior research has shown that age of first intoxication (AI) is associated with negative alcohol outcomes, limited research has examined factors accounting for this relationship. Alcohol expectancies, or beliefs about the effects of alcohol, may explain such associations as both positive and negative expectancies have been shown to be key predictors of drinking outcomes. Objective: The present study examined expectancies as mediators between early AI and alcohol-related outcomes. Method: Data collection occurred in 2012 and 2013. Participants were college students (N = 562, 65.8% women) who completed an online survey including measures of alcohol use history, alcohol expectancies, typical alcohol consumption, and alcohol-related problems. Structural equation modeling was used to test the hypothesized model. Results: Our findings support a model whereby AI is associated with drinking through its influence on both positive and negative expectancies. Specifically, an earlier AI was associated with stronger alcohol expectancies, which in turn, was associated with heavier alcohol use and alcohol-related problems. Conclusions/Importance: These findings are consistent with expectancy theory and previous research suggesting that more experienced drinkers hold stronger drinking-related beliefs, be it positive or negative, and these expectancies ultimately explain variability in alcohol use and problems. Our findings further support that expectancies play an important role in the initiation of drinking behavior.     

Relationship between General and Sport-Related Drinking Motives and Athlete Alcohol Use and Problems

Objective: Alcohol use (and adverse consequences due to alcohol use) among college student-athletes is a common occurrence and consequently garners attention as a health concern within athletic departments and the NCAA. One of the strongest predictors of alcohol use in athletes is motivation to drink. However, not much is known about the influence of alcohol use motivations on drinking in collegiate athletes. Therefore, this study examined the influence of sport-related and general drinking motives on alcohol use and alcohol-related problems. Method: Participants were female collegiate softball players (N?=?721) from 62 NCAA teams. Athletes completed the Athlete Drinking Scale (Martens et al., 2005), the Drinking Motives Questionnaire, revised (Cooper, 1994; Cooper et al., 1992), alcohol consumption measures, and the Rutgers Alcohol Problems Index (White & Labouvie, 1989). Multilevel modeling was used to analyze the data. Results: Higher scores on Positive Reinforcement motives were associated with greater alcohol consumption, heavy episodic drinking, and alcohol-related problems. Enhancement motives were positively associated with heavy episodic drinking and alcohol-related problems, while Coping motives were positively associated with alcohol-related problems. Lower scores on Conformity motives were related to higher alcohol consumption, whereas higher scores were related to more alcohol-related problems. Conclusions: These results assist in understanding salient drinking motives among athletes while accounting for nesting effects of athletes within teams. Results demonstrate alcohol use as a perceived means of reward for hard work or good athletic performance, thus attempts to control alcohol use in college athletics should emphasize alternative methods to positively reinforce efforts or celebrate victories.     

It's Game Time: Drinking Intentions,Alcohol Consumption,and Consequences at College Tailgates

Background: Alcohol consumption and related consequences is a problem on many college campuses. Tailgating parties before college sporting events may be contributing, however, little recent research has investigated alcohol consumption at these events. Objective: The purpose of this study is to evaluate the drinking behaviors of college game day tailgate attendees and subsequent alcohol-related consequences. Methods: Participants (N = 89; 44.9% female) were recruited from tailgates at a university in the Midwest United States on college football game days during fall 2014. Participants provided a breath sample, completed a questionnaire, and were given the opportunity to participate in a follow-up survey (n = 62) to assess resulting alcohol-related consequences. Results: Over half of participants had BrACs greater than 0.000. However, one in three participants reported intentions to abstain from alcohol or to drink but not enough to get buzzed. Intoxication intentions were a significant and unique predictor of alcohol consumption and experience with alcohol-related consequences at follow-up. Conclusions/Importance: This study updates and extends the literature on alcohol-related consequences in the context of college football tailgates. The results suggest that consequences may be prevented through changes in intentions to become intoxicated.     

College Student Dating Partner Drinking Profiles: Differences in Relationship Functioning and Relationship-Specific Alcohol Expectancies

Background: Although the majority of research on partner drinking styles has examined married couples, dating partners may influence one another's problem behaviors including alcohol use. Objectives: This study identified patterns of at-risk alcohol use in college women and their dating partners using a person-centered statistical approach (i.e., latent profile analysis). Methods: Participants were 286 college student women in dating relationships. They completed questionnaires regarding their own and their partners' drinking, alcohol use severity, intimate partner violence (IPV), relationship satisfaction, and relationship-specific alcohol expectancies. Data were collected in 2012 through 2013. Results: Results revealed three distinct, latent classes based on both partners' alcohol outcomes. The “Low-Risk” group (58%) consisted of non-heavy drinking partners. In the “High-Risk – Higher Men” class (27%), men drank more than women; however, both men and women were high-risk drinkers. The “High-Risk – Higher Women” group (15%) consisted of high-risk drinking partners but women consumed more alcohol than men. Both high-risk couple groups were more dissatisfied in their relationships and experienced more IPV, but held stronger beliefs about how alcohol influenced their relationship. Conclusions/Importance: Findings indicate that there are several distinct classes of dating couples that differ in relationship problems and beliefs about alcohol's impact on their relationship. Riskier couples differ in behaviors and alcohol-related beliefs from low-risk couples. These findings may inform the development of more efficacious alcohol interventions tailored toward high-risk drinking dating couples.     

Moderators of the Effects of Alcohol Protective Behavioral Strategies: Three Attempts of Replication and Extension

Background: Protective behavioral strategies (PBS) can be used to reduce alcohol-related harm when drinking. Despite much research demonstrating that use of protective behavioral strategies (PBS) is associated with decreased alcohol use/problems, few studies have examined moderators of these associations. Moderation tests are important as they define the boundary conditions of the protective effects of PBS use (i.e., identify for whom and in what context PBS use reduces harm). Objectives: We aimed to replicate and extend the findings from three published studies that have examined putative moderators of PBS-alcohol associations: self-regulation, negative urgency, and drinking refusal self-efficacy. Method: Participants were recruited from a psychology department participant pool at a large, southwestern university in the United States (N = 628). Results: Although we replicated most main effects and bivariate correlations, we failed to replicate any of the moderation effects (i.e., interaction effects). Conclusions/Importance: We urge PBS researchers to attempt to replicate moderation effects in independent samples to determine these effects' reproducibility. Limitations and future directions are discussed.     

Use of Alcohol Protective Behavioral Strategies as a Moderator of the Alcohol Use–Consequences Relationship: Evidence from Multiple Replications

Background: The use of protective behavioral strategies (PBS) has been found to attenuate the relationship between alcohol use and related consequences. Objectives: The current study examined PBS use as a moderator of the association between alcohol use and consequences in multiple samples (N?= 9) of college students with different sample sizes (e.g., ns 125–736). We also examined sex as a moderator of the PBS moderation analyses. Across all samples, we predicted that the use of more PBS would attenuate the use–consequences relation. Methods: In total, 3,524 college students completed online measures of alcohol use, consequences, and PBS use (i.e., PBSS) across two sites. Conclusions/importance: In the analyses, 3 two-way interactions were consistent with the literature (i.e., use–consequences relation weakest among those with high PBS use), 6 were opposite of what was reported in the literature (i.e., use–consequences relation strongest among those with high PBS use), and 39 were not statistically significant. These results corroborate, contradict, and extend the current body of knowledge in the extant alcohol PBS literature. In the examination of three-way interactions in the combined sample, serious harm reduction (SHR) PBS was found to moderate the use–consequences relation among female, but not among male students. Specifically, the use–consequences relation was weakest among female students who used more SHR PBS indicating that SHR PBS may be an important intervention target for female college students. Additional experimental and longitudinal studies are needed to examine the effects of PBS use on the use–consequences relation.     

A cross-lagged panel model examining protective behavioral strategies: Are types of strategies differentially related to alcohol use and consequences?

Protective behavioral strategies (PBS) are skills that can be used to reduce the risk of alcohol-related negative consequences. Studies have shown that, in general, PBS are related to less alcohol consumption and fewer negative consequences; however, other studies have suggested that not all types of PBS (e.g., stopping/limiting drinking [SLD], manner of drinking [MOD] and serious harm reduction [SHR]) are equally effective at reducing alcohol risk. In addition, few studies have explored the longitudinal relationships among PBS, alcohol use and consequences. Using a sample of heavy drinking college students (N = 338), the current study examined PBS use, alcohol consumption and consequences across two time points three months apart. Cross-lagged panel models revealed that MOD predicted a reduction in alcohol use and negative consequences. SHR was longitudinally related to fewer negative consequences, but unrelated to alcohol use. SLD was not associated with drinking or consequences at follow-up. These results highlight the need for future research to examine the effects of different types of PBS and have implications for alcohol intervention programs that incorporate PBS skills training.     

Depressive symptoms,ruminative thinking,drinking motives,and alcohol outcomes: A multiple mediation model among college students in three countries

BackgroundRecent research suggests that ruminative thinking (specifically problem-focused thoughts) may explain why individuals engage in drinking to cope (DTC) when dealing with depressive symptoms; which in turn leads to increased negative alcohol-related consequences. Cross-cultural studies addressing these phenomena are scarce.ObjectivesThe present study cross-culturally tested whether four rumination facets (problem-focused thoughts, counterfactual thinking, repetitive thoughts, and anticipatory thoughts) uniquely mediate the relationships between depressive symptoms and drinking motives/alcohol outcomes in a multicultural sample of college student drinkers (n = 1429) from Spain, Argentina, and the U.S.MethodStructural equation modeling was conducted to test the models, controlling for sex. Further, we conducted invariance testing to determine whether our models were culturally-specific or culturally-universal.ResultsWithin both proposed models, no rumination facet uniquely mediated the relationship between depressive symptoms and drinking motives. However, an exploratory model with a second-order latent factor of ruminative thinking did significantly mediate these associations (exception was conformity motives). Further, there were two significant double-mediated associations that suggested that increased depressive symptoms is associated with increased ruminative thinking, which is associated with higher DTC motives, which in turn is associated with higher alcohol consumption and negative alcohol-related consequences. All models were found to be invariant across countries and sex, suggesting that these associations may be relatively universal.ConclusionsRumination is relevant to understand the increased vulnerability of college drinkers to exhibit greater alcohol consumption and negative consequences via DTC motives when dealing with depressive symptoms.     

Alcohol expectancies,protective behavioral strategies,and alcohol-related outcomes: A moderated mediation study

Aims: The influence of alcohol expectancies on alcohol consumption and the negative consequences of alcohol consumption among college students has been well documented. Protective behavioral strategies are associated with decreases in alcohol use and related consequences. This study examined the extent to which the use of protective behavioral strategies mediated the influence that alcohol expectancies had for alcohol consumption and negative alcohol-related consequences.

Methods: Measures of expectancies about alcohol consumption, protective behavioral strategies used when consuming alcohol, amount of alcohol consumed and negative consequences associated with alcohol use were completed by 679 traditional age undergraduate students via a secure website. A moderated mediation data analytic strategy was employed because of the gender differences that have been observed for alcohol expectancies, consumption, and consequences.

Findings: The use of protective behavioral strategies was found to mediate the associations that positive expectancies had with both the amount of alcohol consumed and the negative consequences of alcohol consumption only for women.

Conclusions: Education and harm reduction efforts for college student drinkers, including expectancy challenge initiatives, would benefit from including information about use of protective behavioral strategies.     

Protective behavioral strategy use and motivations for drinking: Exploring Alternatives to Drinking strategies

Protective behavioral strategy (PBS) use is associated with less alcohol consumption and fewer alcohol-related problems. Further, greater endorsement of social or enhancement drinking motives (i.e., positive motives) is associated with less frequent PBS use. Limited research has, however, explored coping or conformity motives (i.e., negative motives) in relation to PBS. Consequently, the present study aimed to (1) identify the types of PBS most strongly associated with negative and positive motives and (2) examine different types of PBS as mediators of the relationship between each drinking motive and alcohol outcomes. Participants were college students (n = 303; 70% women) who completed measures of drinking motives, PBS, alcohol use, and alcohol-related problems. Results indicated that greater endorsement of positive drinking motives were more strongly associated with less frequent use of PBS while drinking whereas negative motives were more strongly related to less frequent Alternatives to Drinking strategy use. Further, strategies used while drinking were more relevant in a model of positive drinking motives and Alternatives to Drinking strategies were more relevant in a model of negative motives. These findings may suggest that whereas individuals with stronger positive motives have difficulty using strategies while drinking, individuals who drink to cope or conform have greater difficulty utilizing Alternatives to Drinking strategies. Based on our results demonstrating that different types of PBS are more relevant for various types of drinkers, it may be important for future interventions to discuss not only the participant's PBS use but also their motivations for consuming alcohol.     

Endorsement of the “firewater myth” affects the use of protective behavioral strategies among American Indian and Alaska Native students

Belief in an American Indian/Alaska Native (AI/AN) specific biological vulnerability (BV) to alcohol problems (aka the “firewater myth”) has been found to be associated with worse alcohol outcomes among AI/AN college students who drink, despite also being associated with greater attempts to reduce drinking. In the current study, we examined the associations of belief in a BV and belief that AI/AN people have more alcohol problems with the use of alcohol protective behavioral strategies (PBS) among AI/AN college students. PBS examined, as measured by the Protective Behavioral Strategies Scale-20, included manner of drinking, limiting/stopping drinking, and serious harm reduction strategies. Participants were college students who identified being AI/AN (n = 137) and had drank in the past month, and were selected from a larger multi-site study on PBS. Mediation models revealed that greater belief in a BV and belief that AI/AN people have more alcohol problems were both negatively associated with manner of drinking, which in turn was associated with greater past month alcohol use and alcohol consequences. These beliefs were not significantly associated with other PBS. Consistent with prior research with other student populations, both manner of drinking and limiting/stopping drinking were associated with less alcohol use and all three domains of PBS were directly associated with fewer alcohol consequences. The results suggest that these beliefs regarding AI/AN people and alcohol negatively affect the use of strategies aimed at avoiding drinking behavior that can lead to rapid drinking and a higher blood alcohol content, contributing to alcohol consequences.     

Factors Associated with Parents' Belief in the Appropriateness of Providing Alcohol to their Child

Background: Parental provision of alcohol to their underage child has been associated with risky adolescent drinking. While parents' belief in the appropriateness of providing their child with alcohol may influence their provision behaviors, research into the factors associated with this belief is lacking. Objectives: This study sought to identify the factors associated with parents' belief in the appropriateness of providing alcohol to their underage child. Methods: Western Australian parents of 12–17 year olds (n = 443) completed an online survey assessing their drinking habits, alcohol provision behaviors, alcohol-related beliefs and attitudes, their child's alcohol consumption, and demographics. Results: Nearly half (44%) the parents surveyed reported providing their underage child with alcohol. Parents of older children and parents who (i) did not believe in the harms and recommendations associated with alcohol use in youth, (ii) agreed with youth-related drinking myths, and (iii) reported more occasions of alcohol consumption by their child were more likely to believe that it was appropriate to provide alcohol to their underage child. Those who believed providing alcohol to their underage child was appropriate were in turn more likely to provide alcohol. Conclusions: Interventions aiming to reduce parental provision of alcohol to children should focus on changing parents' beliefs that this is an appropriate harm minimization behavior. Belief change may be facilitated by the implementation of public education campaigns that increase parents' belief in the alcohol-related harms associated with youth drinking and debunk youth-related drinking myths.     

Protective Behavioral Strategies Moderate the Association between Narcissistic Traits and Alcohol Pathology in College Student Drinkers

Background: Personality traits found in Cluster B personality disorders have garnered considerable empirical attention and have been linked to a litany of issues, such as alcohol-related problems. While psychopathic traits have been linked to alcohol-use consequences, narcissistic traits remain understudied. Objectives: The current study examines the relationship between narcissistic traits and alcohol use and consequences as a function of Protective Behavioral Strategies (PBS) in a sample of college students. Method: Participants (n?=?387 college student drinkers; 69.25% female) completed a series of questionnaires assessing alcohol use and consequences, PBS use, and narcissistic traits. Results: There was a significant positive association between narcissistic traits and alcohol use and consequences. The interaction of PBS and narcissistic traits was also statistically significant. Simple slopes revealed that at high levels of PBS (+1SD), the relationship between narcissistic traits and alcohol-use consequences was attenuated and not significant, while at low levels of PBS (–1SD), this association was potentiated. Conclusion: These findings suggest that interventions targeting PBS use may be one way to reduce alcohol problems among those with higher levels of narcissistic traits.     

Simultaneous Use of Alcohol and Marijuana: Patterns and Individual Differences

Background: Simultaneous alcohol and marijuana (SAM) use, or using alcohol and marijuana in such a way that their effects overlap, is associated with negative health and behavioral outcomes. Objectives: Our study sought to fill gaps in our knowledge on this emerging public health concern by comparing SAM users and alcohol-only users on individual-level factors and substance use outcomes as well as examining associations of SAM use frequency, within users. Methods: Participants were recruited through online postings. Our analytic sample consisted of 1017 young adults (18–25?years) who reported past-month alcohol use. Most were male (67.8%), Caucasian (71.5%), and had attended at least some college (74.8%). Results: Past-year SAM users reported higher levels of sensation seeking and greater perceptions of their close friends’ drinking behavior in comparison to alcohol-only users. SAM users reported heavier and more frequent alcohol use than alcohol-only users. Within past-year SAM users, 70% reported SAM use at least weekly. More frequent SAM use was associated with all alcohol use outcomes (e.g., weekly quantity, frequency, alcohol-related problems) and marijuana use outcomes (e.g., quantity, frequency, peak use) and higher drinking norms. Conclusions/Importance: It is clear that SAM users are a vulnerable sub-population of young adult drinkers. SAM users are differentiated from alcohol-only users in terms of their personality characteristics and perceptions of peer groups’ drinking. SAM users and more frequent users are also at heightened risk for substance use outcomes. Prevention and intervention efforts targeting high-risk drinking may benefit from also assessing whether they simultaneously use alcohol and marijuana.
