College Students With Military Experience Report Greater Alcohol-Related Consequences

This study examined associations among military experience, alcohol use, and alcohol-related consequences among a large national sample of 27,249 students pursuing postsecondary education. Because of the uniqueness of the developmental period of emerging adulthood, we stratified all analyses by age groups of 18–24 and 25 and older. There were no differences between students with and without military service history in terms of 3 indicators of alcohol use: alcohol consumption in the last 30 days, binge drinking in the last 2 weeks, and drinking and driving in the last 30 days. There were, however, several differences in self-reported consequences of drinking. Among individuals ages 18–24, students with military service history had nearly twofold increased odds of police encounters as a consequence of drinking (adjusted odds ratio [aOR] = 1.91, 95% confidence interval [CI] [1.02, 3.57]) and increased odds greater than twofold of experiencing nonconsensual sex (aOR = 2.68, 95% CI [1.17, 6.19]). Among both age groups, students with military service history reported greater odds of having unprotected sex as a consequence of drinking when compared to students without military service history. Research is needed to identify the reasons why alcohol use results in these particular negative consequences for students with military service history, which can inform prevention and intervention efforts.     

Patterns and correlates of binge drinking trajectories from early adolescence to young adulthood.

Latent growth mixture modeling was used to identify developmental trajectories (described in terms of demographics, exposure and resistance to a pro-drug environment, and deviant behavior) of binge drinking among 5,694 individuals who completed 6 surveys from ages 13 to 23 years: nonbingers (32%); moderate stables (37%), who had consistently low levels of bingeing; steady increasers (16%), who increased from the lowest to highest level of bingeing; adolescent bingers (9%), whose early rise in bingeing was followed by a decrease to a moderate level; and early highs (6%), who decreased from the highest level of bingeing to a moderate level. Results show considerable diversity in binge drinking patterns and the correlates of bingeing across trajectory classes.     

Binge drinking and violence against dating partners: the mediating effect of antisocial traits and behaviors in a multinational perspective

Research has consistently shown a link between alcohol use and partner violence (PV). Little is known concerning the strength of this association across cultures and genders, and few have assessed possible mediators. This study assesses the link between binge drinking and PV among 7,921 college students in 38 sites around the world, and investigates the mediating role of antisocial traits and behaviors (ASTB). A significant association was found between binge drinking and PV, the strength of which differed by site but not by gender. ASTB fully mediated this association. The mean level of binge drinking at each site did not significantly influence the strength of the association between binge drinking and PV.     

Transactional models between personality and alcohol involvement: a further examination

Although correlated changes between personality and alcohol involvement have been shown, the functional relation between these constructs is also of theoretical and clinical interest. Using bivariate latent difference score models, we examined transactional relations (i.e., personality predicting changes in alcohol involvement, which in turn predicts changes in personality) across two distinct but overlapping developmental time frames (i.e., across college and during young adulthood) using two large, prospective samples. Across college, there was some evidence that alcohol involvement predicted changes in personality; however, these findings were limited to models that included more proximal measures of alcohol use. When examined across a longer timeframe, we found no evidence that alcohol involvement significantly predicted changes in personality but found some evidence that personality predicted changes in alcohol use. We did find reliable evidence of correlated changes between personality and alcohol use, especially during emerging adulthood. The findings from our datasets highlight that the impact of alcohol involvement on personality change may be limited to shorter intervals during specific developmental time-frames and that the relation between changes in personality and alcohol involvement may be best viewed from a noncausal perspective.     

Increased sensitivity to the disinhibiting effects of alcohol in binge drinkers.

Heavy episodic alcohol use, or binge drinking, is a serious public health problem. Binge drinking is endemic in college students and has resulted in numerous alcohol-related tragedies, including acute alcohol poisonings, falls, and automobile collisions. Such negative outcomes might occur because binge drinkers are generally more impulsive, and this impulsivity might be exacerbated under alcohol. The purpose of this study was to examine this hypothesis by comparing the acute effects of alcohol on a cognitive measure of behavioral control in binge and nonbinge drinkers. The results indicated that binge drinkers act more impulsively and report feeling more stimulated under an acute 0.65 g/kg dose of alcohol compared to nonbinge drinkers. The present finding of a heightened disinhibitory reaction to alcohol in binge drinkers may help explain the link between impulsivity and problem drinking at a more fundamental level of behavioral control.     

The influence of peers on young adult substance use.

Data collected from 294 young adults, ages 19 to 25, and both a same- and an opposite-gender best friend or mate across 3 annual assessments were analyzed to examine the similarity to and influence of the peer on the young adult's substance use. The authors found similarity across time between both peers and the young adult in cigarette use, alcohol use, binge drinking, and, in most cases, marijuana use. In prospective analyses, peer use predicted young adult cigarette use, binge drinking, and problem use by the young adults. Results were generally consistent across gender and for both same- and opposite-gender peers. Findings emphasize peer influence contribution to young adult substance use and suggest the design of interventions that involve both young adults and their peers.     

Protective behavioral strategies and the relationship between depressive symptoms and alcohol-related negative consequences among college students

Approximately 40% of college students reported engaging in heavy episodic or "binge" drinking in the 2 weeks prior to being surveyed. Research indicates that college students suffering from depression are more likely to report experiencing negative consequences related to their drinking than other students are. The reasons for this relationship have not been well-studied. Hence, the purpose of this study was to determine whether use of protective behavioral strategies (PBS), defined as cognitive-behavioral strategies an individual can use when drinking alcohol that limit both consumption and alcohol-related problems, mediated the relationship between depressive symptoms and alcohol-related negative consequences among college students. Data were obtained from 686 participants from a large, public university who were referred to an alcohol intervention as a result of violating on-campus alcohol policies. Results from structural equation modeling analyses indicated that use of PBS partially mediated the relationship between depressive symptoms and alcohol-related negative consequences. Implications for clinicians treating college students who report experiencing depressive symptoms or consuming alcohol are discussed.

Bidirectional relations between different forms of prosocial behaviors and substance use among female college student athletes

Bidirectional, longitudinal relations between alcohol and marijuana use and prosocial behaviors in women college student athletes were examined. Participants were 187 female college students (M_age = 19.87 years; 91% White) who completed questionnaires on their use of marijuana and alcohol, and six forms of prosocial behaviors across 6 years (2004–2010). The findings yield overall evidence that earlier marijuana use predicted lower levels of most specific forms of prosocial behaviors for women athletes in later young adulthood. Early expressions of altruistic behaviors predicted less marijuana use in later young adulthood. Expression of public prosocial behaviors early in young adulthood predicted higher levels of hazardous drinking in late young adulthood. These novel findings have important implications for links between prosocial development and substance use in women college athletes.     

Conjoint developmental trajectories of young adult alcohol and tobacco use

Developmental and etiological advances have set the stage for considering trajectories of problem behavior across the life course, but little work thus far addresses co-occurring problem behavior trajectories. Although recent work characterizes drinking and smoking trajectories, none has explored the course of concurrent drinking and smoking. Using panel data from the Monitoring the Future Project (N=32,087), the authors applied growth mixture modeling to 4 waves of heavy drinking and smoking in a young-adult sample. The authors extracted a single latent group membership factor from heavy drinking and smoking. Associations between trajectory classes and risk factors were relatively unique to the substance being predicted. The association of smoking with alcohol expectancies and delinquency appeared to exist by virtue of smoking's comorbidity with drinking.     

Motivational pathways to alcohol use and abuse among Black and White adolescents

Using data from a biracial community sample of adolescents, the present study examined trajectories of alcohol use and abuse over a 15-year period, from adolescence into young adulthood, as well as the extent to which these trajectories were differentially predicted by coping and enhancement motives for alcohol use among the 2 groups. Coping and enhancement motivations (M. L. Cooper, 1994) refer to the strategic use of alcohol to regulate negative and positive emotions, respectively. Results showed that Black and White youth follow distinct alcohol trajectories from adolescence into young adulthood and that these trajectories are differentially rooted in the regulation of negative and positive emotions. Among Black drinkers, coping motives assessed in adolescence more strongly forecast differences in alcohol involvement into their early 30s, whereas enhancement motives more strongly forecast differences among White drinkers. Results of the present study suggest that different models may be needed to account for drinking behavior among Blacks and Whites and that different approaches may prove maximally effective in reducing heavy or problem drinking among the 2 groups.     

Binge Drinking Among College Athletes and Non-Athletes

Concerns about incidence, forms, and consequences of alcohol use among college students lack examinations of the lifestyles and predictors of college student athletes. This article, using a sample of student-athletes and non-athletes from four Southern universities, identifies the lifestyle predictors for each population, identifying patterns and sets of predictors of binge drinking behavior. Findings indicate that for both samples, binge drinking behavior is explained by sex, drinking in bars, number of male friends who drink, and cigarette smoking. Student-athletes' binge drinking is explained further by residing on campus. Non-athlete binge drinking is related to race and amount of study time per week. Implications for these findings are also discussed.     

Substance Use Progression from Adolescence to Early Adulthood: Effortful Control in the Context of Friendship Influence and Early-Onset Use

In a sample of 998 ethnically diverse adolescents, a multiagent, multimethod approach to the measurement of adolescent effortful control, adolescent substance use, and friendship influence was used to predict escalations to early-adult tobacco, alcohol, and marijuana use by ages 22-23. Structural equation modeling revealed that adolescent substance use and friends' substance use tended to be highly correlated and together were robust predictors of a problematic pattern of usage for all substances in early adulthood. In addition, the adolescent effortful control construct directly predicted progressions to problematic use of tobacco and marijuana, but not for alcohol. In the alcohol model, effortful control interacted with the construct of substance use lifestyle (based on adolescent alcohol use and friends' substance use) when predicting problematic alcohol use in early adulthood. Results held when comparing across genders and across ethnic groups. These findings emphasize the importance of addressing adolescent self-regulation in interventions designed to treat and prevent early-adult substance abuse.     

Evaluations and expectancies of alcohol and marijuana problems among college students.

Two studies examined the associations between evaluations (good-bad) and expected likelihood (likely-unlikely) of alcohol- and marijuana-related problems and hazardous consumption and problems among college students. Participants provided data on alcohol use, alcohol-related problems, and expectancies and evaluations of alcohol problems; marijuana use indices, marijuana-related problems, marijuana effect expectancies, and likelihood and evaluations of marijuana problems. Evaluations of alcohol problems were positively related to the number of binge drinking occasions and alcohol-related problems. The interaction between evaluations and expectancies was significant in predicting the number of binge drinking occasions. Expectancies demonstrated a curvilinear relationship with binge drinking and alcohol-related problems. Marijuana users evaluated marijuana-related problems as less negative and less likely to occur than did nonusers. Expectancies, but not evaluations, of negative consequences were significantly associated with marijuana use intensity. Expectancies of problems demonstrated a curvilinear relationship with marijuana-use intensity and marijuana problems. Men evaluated alcohol and marijuana problems less negatively than did women. In summary, the expected likelihood of alcohol-marijuana problems and the evaluation of such problems represent a vulnerability factor associated with increased liability for hazardous alcohol and marijuana use.     

Trajectories of alcohol and drug use and dependence from adolescence to adulthood: the effects of familial alcoholism and personality

This study describes trajectories of substance use and dependence from adolescence to adulthood. Identified consumption groups include heavy drinking/heavy drug use, moderate drinking/experimental drug use, and light drinking/rare drug use. Dependence groups include alcohol only, drug only, and comorbid groups. The heavy drinking/heavy drug use group was at risk for alcohol and drug dependence and persistent dependence and showed more familial alcoholism, negative emotionality, and low constraint. The moderate drinking/experimental drug use group was at risk for alcohol dependence but not comorbid or persistent dependence and showed less negative emotionality and higher constraint. Familial alcoholism raised risk for alcohol and drug use and dependence in part because children from alcoholic families were more impulsive and lower in agreeableness.     

Putting the relationship between social anxiety and alcohol use into context: A daily diary investigation of drinking in response to embarrassing events

The goal of this study was to clarify mixed findings regarding the association between dispositional social anxiety and drinking among college students by using a daily diary method to examine whether a within-person social-contextual event moderated the relationship between social anxiety and alcohol use. College students (n = 476) completed a measure of dispositional social anxiety and then for 30 days reported whether they experienced an embarrassing event in public and the amount of alcohol they drank each day. We examined whether experiencing an embarrassing event moderated the relationship between dispositional social anxiety and alcohol use for same-day, same-evening, next-day, and next-evening drinking. While there was a positive relationship between dispositional social anxiety and alcohol use on evenings when an embarrassing event occurred earlier that day, this appeared to be driven by a reduction in drinking among those low in social anxiety. Individuals with high social anxiety drank in the evening regardless of embarrassing event occurrence. Results suggest that people with low social anxiety show an adaptive response to embarrassing events by lowering drinking on such evenings, while those with high social anxiety may drink to reduce their already high levels of anxiety independent of daily social events.     

Binge eating proneness emerges during puberty in female rats: a longitudinal study

Puberty is a critical risk period for binge eating and eating disorders characterized by binge eating. Previous research focused almost entirely on psychosocial risk factors during puberty to the relative exclusion of biological influences. The current study addressed this gap by examining the emergence of binge eating during puberty in a rat model. We predicted that there would be minimal differences in binge eating proneness during pre-early puberty, but significant differences would emerge during puberty. Two independent samples of female Sprague-Dawley rats (n = 30 and n = 36) were followed longitudinally across pre-early puberty, mid-late puberty, and adulthood. Binge eating proneness was defined using the binge eating resistant (BER)/binge eating prone (BEP) model of binge eating that identifies BER and BEP rats in adulthood. Across two samples of rats, binge eating proneness emerged during puberty. Mixed linear models showed little difference in palatable food intake between BER and BEP rats during pre-early puberty, but significant group differences emerged during mid-late puberty and adulthood. Group differences could not be accounted for by changes in nonpalatable food intake or body weight. Similar to patterns in humans, individual differences in binge eating emerge during puberty in female rats. These findings provide strong confirming evidence for the importance of biological risk factors in developmental trajectories of binge eating risk across adolescence.     

Examining the Relationship of Substance Use and Sexual Orientation

In this article we examine the effects of self-reported sexual orientation on substance abuse. Using data on a random sample of 6,713 individuals in Washington State, this study examines causes and correlates of substance use by sexual minorities, an at-risk and treatment underserved population. Logistic regression results indicate homosexual orientation is a significant positive predictor of past year marijuana use, past year hard drug use, past year binge drinking, and lifetime alcohol addiction. Bisexual orientation is a significant predictor of past year marijuana use, past year hard drug use, and past year binge drinking. Potential causal mechanisms for these elevated patterns of substance use are discussed.     

Gender differences in drinking motivations and outcomes.

To investigate gender differences in the dynamics of alcohol use, we gathered self-reported data from male and female college students. Results of our experiment showed that dominance power motivations were correlated with negative drinking outcomes for both men and women; assertiveness power motivations were associated with negative outcomes only for women. For both sexes, a higher proportion of positive social motivations was associated with fewer negative drinking outcomes. We expect that, in addition to the more traditionally defined needs for dominance power shown to be important for drinking among men, women may use alcohol in relation to needs for assertiveness and self-expression.     

Alcohol expectancy and the relationship between drinking and physical aggression

This study investigated the role of alcohol expectancy as a moderator of the relationship between drinking habits and self-reported frequency of physical aggression. Questionnaires were administered to a sample of 114 American male college students. After controlling for the subjects' ages, hostility, and attitude toward aggression, the relationship between drinking habits and frequency of physical aggression was significantly stronger for those expecting alcohol to increase aggression than for those expecting either a decrease or no effect on aggression. This finding lends support to expectancy-based explanations of alcohol's effects.     

Depression, self-esteem, and anger in emerging adulthood: seven-year trajectories

This study used a school-based community sample (N=920) to examine trajectories of depressive symptoms, self-esteem, and expressed anger in the critical years of emerging adulthood (ages 18-25). Using data from 5 waves, the authors discovered that multilevel models indicated that, on average, depressive symptoms and expressed anger declined, whereas self-esteem increased. Between-persons predictors of variability in trajectories included gender (gender gaps in depressive symptoms and self-esteem narrowed), parents' education, and conflict with parents (depressive symptoms and expressed anger improved fastest in participants with highly educated parents and in those with higher conflict). Across time, increases in social support and marriage were associated with increased psychological well-being, whereas longer periods of unemployment were connected with higher depression and lower self-esteem. Emerging adulthood is a time of improving psychological well-being, but individual trajectories depend on specific individual and family characteristics as well as role changes.
