Dimensions of acculturation: Associations with health risk behaviors among college students from immigrant families.

In the present study, we examined a bidimensional model of acculturation (which includes both heritage and U.S. practices, values, and identifications) in relation to hazardous alcohol use, illicit drug use, unsafe sexual behavior, and impaired driving. A sample of 3,251 first- and second-generation immigrant students from 30 U.S. colleges and universities completed measures of behavioral acculturation; cultural values (individualism, collectivism, and self-construal); ethnic and U.S. identity; and patterns of alcohol and drug use, engagement in potentially unsafe sexual activities, and driving while (or riding with a driver who was) intoxicated. Results indicate that heritage practices and collectivist values were generally protective against health risk behaviors, with collectivist values most strongly and consistently protective. Nonetheless, heritage identifications were positively associated with sexual risk taking for Hispanics. U.S. practices, values, and identifications were not consistently related to risk behavior participation. Results are discussed in terms of bidimensional approaches to acculturation, the immigrant paradox, and implications for counseling practice.

Drinking Motives as Mediators of Social Anxiety and Hazardous Drinking Among College Students

Although social anxiety (SA) and alcohol use disorders commonly co-occur, the relationship between these variables in college populations has been inconsistent. The present study tested the hypothesized model that negatively reinforcing, but not positively reinforcing, drinking motives (or reasons for drinking) would mediate the association between SA and three aspects of hazardous drinking (quantity/frequency, consequences, and dependence symptoms) in an ethnically diverse sample of college drinkers (N = 817; mean age = 19.9 years, range = 18–29). Structural equation modeling (SEM) results using the asymmetrical distribution of products test indicated that coping motives partially mediated the relationship between SA and negative consequences and dependence symptoms but not the quantity/frequency outcome. Contrary to the hypothesized model, conformity motives did not mediate the association between SA and hazardous drinking. As expected, positive reinforcement motives did not mediate the SA–hazardous drinking association. Multigroup SEM analyses revealed that the mediation models did not differ for men (n = 215) and women (n = 602). Overall, the present findings support extant research and theoretical models regarding the mediating role of coping motives in the relationship between SA and problem drinking, suggesting a potential pathway for the development and maintenance of SA and alcohol use disorder comorbidity. Such findings could contribute to improved intervention programs by targeting coping drinking motives and building coping skills.

Alcohol Use Motives among Traumatic Event-Exposed, Treatment-Seeking Adolescents: Associations with Posttraumatic Stress

The current study evaluated the linkage between posttraumatic stress symptoms and alcohol use motives among 49 traumatic event-exposed adolescents (M(age)=16.39 years). It was hypothesized that posttraumatic stress symptom levels would be positively associated with coping-related drinking motives specifically (cf., social, enhancement, or conformity motives) and that coping-related drinking motives would evidence associations with the hyperarousal and reexperiencing posttraumatic stress symptom types. Findings were consistent with hypotheses, suggesting traumatic event-exposed adolescents may be using alcohol to manage posttraumatic stress symptoms.

Social anxiety and motives for alcohol use among adolescents.

Social anxiety evidences significant comorbidity with alcohol use disorders and alcohol-related problems. In an effort to better understand this co-occurrence, researchers are beginning to evaluate specific drinking-related factors, including alcohol use motives, among socially anxious individuals. Drawing on Coopers (1994) 4-factor model of drinking motives (enhancement, social, conformity, coping), a growing body of work suggests that socially anxious individuals may consume alcohol in an effort to cope with their anxious symptoms; however, no study to date has examined these relations among youth. Accordingly, we examined alcohol use motives as a function of social anxiety in a community-based sample of 50 adolescents ages 12 to 17 years (Mage = 16.35, SD = 1.10). As predicted, heightened social anxiety was associated with elevated coping-related drinking motives. More important, other alcohol-use motives did not vary as a function of social anxiety. Collectively, these findings uniquely extend research conducted with adults, and suggest socially anxious youth may be motivated to use alcohol to manage their anxious arousal.

Alcohol Outcome Expectancies and Drinking to Cope with Social Situations

Repeated use of alcohol as a coping strategy to reduce anxiety or discomfort increases ones risk of developing alcohol dependence. Previous studies have found alcohol outcome expectancies (AOE) strongly predict drinking behavior, in general, and also are related to drinking to cope. The purpose of the current study was to examine AOE that may be related to drinking to cope with discomfort in social situations. It was hypothesized that positive AOE, especially related to assertion and tension reduction, would be most associated with drinking to cope with social situations. Fifty-six community volunteers from a larger study on attentional bias and drinking to cope were divided into high (n=36) and low (n=20) drinking to cope groups following completion of a questionnaire battery. Findings indicated AOE were well able to classify drinking to cope status, with 91% of cases correctly classified. As hypothesized, assertion and tension reduction AOE uniquely contributed to the discriminant function in classifying drinking to cope groups. These findings have implications for the prevention and treatment of alcohol use disorders and suggest that AOE should be further investigated as potential moderators of the relationship between social anxiety and alcohol use disorders.

No fear, just relax and play: social anxiety, alcohol expectancies, and drinking games among college students

Abstract Objective: The authors examined the association between social anxiety and drinking game (DG) involvement as well as the moderating role of social anxiety–relevant alcohol outcome expectancies (AOE) in social anxiety and DG involvement among college students. Participants: Participants were 715 students (74.8% women, M age = 19.46, SD = 1.22) from 8 US colleges. Methods: Data were collected via self-report survey from Fall 2005 to Spring 2007. Results: Tension Reduction and Liquid Courage AOE moderated the association between social anxiety and DG participation. Tension Reduction AOE and DG participation were positively related among those with high social anxiety, but were associated negatively for those with low social anxiety. Liquid Courage AOE were associated with increased DG participation for those with low social anxiety, but not for those with high social anxiety. Conclusions: Findings suggest that social anxiety acts as a protective or a risk factor for DG participation among college students, depending upon AOE.

A Critical Review of Laboratory-Based Studies Examining the Relationships of Social Anxiety and Alcohol Intake

Research has revealed inconsistencies regarding the relationship between social anxiety and alcohol use. The goal of the current review is to examine lab-based studies that have been conducted in an attempt to help disentangle the social anxiety - alcohol link. Specifically, this review focuses on the most prominent theories present in this area of research, namely, the Tension Reduction Theory, the Stress-Response Dampening Model, the Self-Awareness Model, the Attention Allocation Model, and the Appraisal-Disruption Model. The review then describes the empirical studies that have been conducted to test predictions derived from each of these theories. This is followed by a discussion of some methodological considerations in this area of research, including an examination of participant characteristics, study selection criteria, alcohol administration procedures, the nature of the anxiety-inducing tasks that have been used in this area of research, and the different types of outcome measures that are typically used to measure social anxiety. The review ends with some tentative conclusions and directions for future research, including recommendations to recruit individuals with high levels of trait social anxiety, to closely monitor blood alcohol levels achieved at different time points during the study, to examine more interaction-based social anxiety provoking tasks, and to employ a wider range of outcome measures (e.g., cognitive and behavioural outcomes relevant to social anxiety).

Pregaming in high school students: relevance to risky drinking practices, alcohol cognitions, and the social drinking context.

Pregaming is the practice of consuming alcohol prior to going out to a social event. Although pregaming has begun to receive research attention in the college setting, very little is known about this risky drinking behavior in high school students. As pregaming has health implications for both students who are college bound and those who are not, we examined the prevalence of this behavior in a sample of high school students who reported current alcohol use and completed pregaming measures (n = 233). The present study examined the associations of gender, age, alcohol expectancies, motivations for drinking (e.g., social, enhancement, and coping), and engagement in other risky drinking practices (i.e., general hazardous use and drinking game participation) with pregaming. Results indicate that pregaming was significantly associated with being older, being a male, having high levels of hazardous alcohol use, and participating in drinking games frequently. Pregaming also occurred most often before parties and sporting events and it was associated positively with frequency of attendance at parties where alcohol is available, the tendency to use alcohol at these parties, and the amount of alcohol consumed at these parties. We discuss the findings in the context of pregaming research that has been conducted with college students, and make suggestions regarding prevention and intervention efforts focused on this risky drinking practice.

Attention to social threat as a vulnerability to the development of comorbid social anxiety disorder and alcohol use disorders: An Avoidance-Coping Cognitive Model

Despite the frequent comorbidity of social anxiety disorder and alcohol use disorders, no theoretical model currently exists to explain the specific mechanisms underlying the comorbidity between these two disorders. An integration of existing theoretical models and empirical evidence across the social anxiety and alcohol use literatures is presented as the Avoidance-Coping Cognitive Model, which proposes that socially anxious individuals may be particularly vulnerable to the anxiolytic effects of alcohol through reductions in attention biases to social threat. The disproportionate reduction in anxiety may then make alcohol an attractive method of avoidance coping. Gaps in the empirical literature are reviewed in light of this model as future directions are suggested.

Do Alcohol Expectancy Outcomes and Valuations Mediate Peer Influences and Lifetime Alcohol Use among Early Adolescents

ABSTRACT Building on the theory of reasoned action (I. Ajzen & M. Fishbein, 1973, 1980; M. Fishbein & I. Ajzen, 1975) and expectancy theory, the authors examined the mediating role of alcohol expectancies in adolescent drinking behaviors by testing whether alcohol expectancy outcomes and valuations (the extent to which these outcomes are perceived as good or bad) mediate the association between peer influences and lifetime alcohol use. Early adolescents (N = 904) from 2 public middle schools in western Michigan completed a battery of questionnaires. Overall, results showed that alcohol expectancies and valuations partially mediated the relations between peer influences (peer use and peer approval) and lifetime alcohol use. The findings suggest that associating with peers who are perceived as using alcohol and approving of drinking may influence adolescents’ alcohol expectancies. The authors briefly discuss future research directions and implications for prevention.
