Testing the Model of Goal-Directed Behavior for Predicting Binge Drinking Among Young People

Background: One of the most problematic modes of alcohol consumption in young adults is risky drinking in single episodes, which typically takes place in social contexts. Several studies have applied the Theory of Planned Behavior to drinking intentions and behavior in young people. However, previous studies show that this model lacks a “bridge” that links a mental process like intentions to a physical process represented by the actual action. Objectives: The aim of the present study is to test the predictive power of the Model of Goal-Directed Behavior plus social influences in order to overcome theory of planned behavior gaps in predicting binge-drinking behavior in young people. Methods: 404 undergraduates completed a questionnaire containing measures for the MGB variables, social identity, and group norms. Two weeks later, participants reported how many times they had had five/four or more alcoholic drinks on a single occasion. Structural equation modeling revealed strong support for model validity. Results: The final equation accounted for 66% in intentions to binge drink, and 48% in drinking behavior, while a planned behavior model accounted for the 47% of variance in intentions to binge and 37% of the drinking behavior. Social influences positively affected desire and intentions to drink. Conclusions: Our findings suggest that, compared to other attitude-behavior frameworks, the MGB is preferable in modeling the proximal determinants of binge drinking. Therefore, the distinction between desire and intention and the consideration of social influences seem to be essential to improve the prediction of binge drinking among young people.     

Smoking Is Associated with Increased Risk of Binge Drinking in a Young Adult Hispanic Population at the US-Mexico Border

Background: This study examines factors related to general health and health behavior, including smoking, that may be associated with binge drinking, drinking “at risk,” and potential for alcohol use disorder among young adults of Mexican ancestry. Methods: A total of 2191 young adult emergency department (ED) patients (18–30 years) of Mexican ancestry in a public hospital proximate to the US-Mexico border completed health surveys while they were waiting to be treated, including questions on general health, drinking, smoking, and drug use. Results: Thirty-seven percent of the study participants reported binge drinking, 38% were “at-risk” alcohol users (above National Institute on Alcohol Abuse and Alcoholism guidelines), and 22% were Rapid Alcohol Problem Screen (RAPS) positive (indicating potential for alcohol use disorder). Smoking was reported by 31%, marijuana use by 16%, and other drug use by 9%. Multiple variable models revealed that smoking was the strongest factor associated with binge drinking. Those who smoked were 3.1 (P < .0001) times more likely to binge drink. Other factors independently associated with binge drinking were age 22–25 years (odds ratio [OR] = 1.5, P = .003), male gender (OR = 1.5, P = .0001), and ED visit for injury (OR = 1.4, P = .007). Conclusions: There is a strong association of smoking and binge drinking. Study findings suggest that brief interventions designed to reduce preventable health risks for young Hispanics should include discussion of both binge drinking and smoking behaviors.     

Daily Reports of Positive and Negative Affect and Alcohol and Marijuana Use Among College Student and Nonstudent Young Adults

Background: Daily affect and substance use covary among college students, but little is known about these associations among young adults not in college. Objectives: The current pilot study examines associations between positive and negative affect and alcohol and marijuana use, with a focus on differences between college student and nonstudent young adults. Methods: High school seniors completed a baseline survey during the spring of 2012 and were then randomly selected to participate in an intensive measurement follow-up. Participants in the follow-up (N = 72, 40.3% men, 77.8% White, 66.7% full-time college students) completed up to 14 consecutive web-based daily surveys during the fall after high school completion. Multilevel models in which days (Level 1) were nested in persons (Level 2) were estimated. Results: Weekend days were associated with increased alcohol use among all young adults, increased marijuana use among college students, and decreased marijuana use among nonstudents. For young adults not in college, greater daily positive affect was associated with increased likelihood of binge drinking, consuming a greater number of drinks, and lower odds of marijuana use; greater daily negative affect was associated with lower odds of alcohol use and lower odds of binge drinking for non-students. For college students, greater daily negative affect was associated with lower odds of marijuana use. Conclusions/Importance: Daily affect and alcohol and marijuana use covary among young adults, though these associations differ between students and non-students. Results highlight the need to examine predictors of alcohol and marijuana use among young adults who do not attend college.     

Trying to Lose Weight and Alcohol Misuse Among High School Girls: Findings From the U.S. National 2011 Youth Risk Behavior Survey

Background: Trying to lose weight has been associated with alcohol use among college-aged females. Excessive drinking along with purging as a method for weight control has been documented in this population. However, little is known about the relationship between alcohol use and trying to lose weight among high school girls. Objectives: To examine the relationship between trying to lose weight and past 30-day (1) alcohol use and (2) binge drinking (separately). Methods: Using data from the National 2011 YRBS, we examined these relationships among 5,106 girls aged 14–18+ who reported ever using alcohol. Survey-weighted iterative logistic regression models were conducted. Results: 44.0% of girls reported current alcohol use with 27.8% reporting binge drinking. While a significant relationship was not found between trying to lose weight and current alcohol use in the final multivariable model, a significant relationship was found between trying to lose weight and binge drinking (AOR: 1.24, 95% CI: 1.02–1.52). Additional variables that were found to be associated with an increased odds of binge drinking included: being in 11th and 12th grades compared to being in 9th grade, screening positively for depression, and current cigarette use. Variables associated with a decreased odds included: talking to an adult/teacher about a problem, and identifying as Black/African American compared to White. Conclusions/Importance: Understanding the relationship between trying to lose weight and binge drinking among high school students is important, as these behaviors may be a precursor to risk behaviors later in life and need to be more fully examined.     

Binge drinking and perceived ethnic discrimination among Hispanics/Latinos: Results from the Hispanic community health study/study of Latinos sociocultural ancillary study

The study assessed whether overall perceived ethnic discrimination and four unique discrimination types were associated with binge drinking in participants from the Hispanic Community Health Study/Study of Latinos who also completed the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study (n = 5,313). In unadjusted analyses that were weighted for sampling strategy and design, each unit increase in discrimination type was associated with a 12–63% increase in odds of binge drinking; however, after adjusting for important demographic variables including age, sex, heritage group, language, and duration of U.S. residence, there was no longer an association between discrimination and binge drinking. Further research still needs to identify the salient factors that contribute to increased risk for binge drinking among Hispanics/Latinos.     

Heterogeneity in Drinking Practices in England and Wales and Its Association With Violent Behavior: A Latent Class Analysis

Background: Crude single-item consumption metrics, such as “binge drinking” measures, mask the complexity and heterogeneity in young people's drinking; thus limiting our understanding of young people's drinking patterns as well as how alcohol drinking is associated with violent outcomes. Objectives: The current study employed a range of consumption and contextual indicators to explore heterogeneity in young people's (16–29 years) drinking practices, giving due consideration to their social nature. It also assessed to what extent heterogeneity in drinking practices was associated with violent outcomes. Methods: Employing data from the 2006 Offending Crime and Justice Survey, three measures of alcohol consumption and nine drinking context indicators were utilized within latent class analysis to create typologies of drinking practices among current drinkers in England and Wales (n = 2711) and examine their association with violent outcomes. The validity of the typologies was also assessed on age, sex, and socio-economic status. Results: Three discernible drinking profiles were identified: “regular social drinkers” (48%), “regular pub binge drinkers” (32%), and “moderate drinkers” (20%). The “regular pub binge drinkers” were found to be more than twice as likely to commit an assault offence (odds ratio = 2.8 95% CI [1.3, 6.2]) when compared to “moderate drinkers” and “regular social drinkers” (odds ratio = 2.2 95% CI [1.4, 3.4]). Conclusions: Interventions aimed at reducing alcohol-related violence ought to give due consideration to the social context of drinking as well as levels of consumption.     

Binge Drinking in African American Males From Adolescence to Young Adulthood: The Protective Influence of Religiosity,Family Connectedness,and Close Friends’ Substance Use

We examined the contribution of culturally relevant protective factors (i.e., adolescent religiosity, family connectedness, and perceived close friends’ substance use) to the probability of young adult binge drinking among African American males. Participants (n = 1,599) drawn from the National Longitudinal Study of Adolescent Health were high school age adolescents (14–18 years, M = 16) at Wave 1 and young adults (18–26, M = 22) at Wave 3. Adolescent binge drinking was associated with all three protective factors. Perceived close friends’ substance use in adolescence was a protective factor in later binge drinking during young adulthood, and was moderated by age such that the effect was stronger for younger adolescents. Implications for culturally relevant research and prevention are discussed.     

Binge Drinking Trajectories from Adolescence to Young Adulthood: The Effects of Peer Social Network

This study investigates an association between social network characteristics and binge drinking from adolescence to young adulthood, utilizing National Longitudinal Study of Adolescent Health (n = 7,966) and employing social network and longitudinal analysis. Lower integration and socialization with alcohol-using peers had immediate risks of binge drinking during adolescence; however, over time, the effects of socialization with alcohol-using peers had the most dramatic reduction. The most prestigious adolescents had the highest longitudinal risks of binge drinking, although they had no immediate risk. Alcohol consumption-related interventions overlooking longitudinal dynamics of social networks may not effectively prevent adolescents from binge drinking in young adulthood.     

Is Binge Drinking Onset Timing Related to Academic Performance,Engagement, and Aspirations Among Youth in the COMPASS Study?

Background: Some evidence suggests early initiation of alcohol use is associated with academic underachievement; however, substance use onset is an ambiguous concept, resulting in mixed findings across studies. Moreover, the quantity of early use is likely an important determinant. Binge drinking is a common pattern among younger cohorts, and is shown to magnify the risk of related problems. Objectives: The current study explored how students who initiated binge drinking early (grade 10 or earlier) or later in high school (grade 11 or 12) differed in relation to a variety of academic indices. Methods: The sample consisted of 19,764 grade 9 to 12 students with at least 2 years of linked-longitudinal data from Year 1(Y₁: 2012-2013), Year 2(Y₂: 2013-2014), and Year 3(Y₃: 2014-2015) of the COMPASS study. Separate multinomial GEE models tested the likelihood of different responses to outcome measures of academic goals, engagement, preparedness, and performance based on the timing of binge drinking onset. Models adjusted for binge drinking initiation in varying frequencies, gender, grade, race/ethnicity, and smoking. Results: Compared to students with earlier onsets of binge drinking, youth with later onsets were more likely to regularly attend class, complete their homework, value good grades, achieve high English or Math marks, have graduate/professional degree ambitions, and expect to obtain a college/trade school diploma after high school, yet they were less likely to expect to achieve a bachelor's degree. Conclusion: Results highlight the importance of substance use prevention programs targeting early adolescents. Both delaying and preventing binge drinking have the potential to improve scholastic outcomes.     

Do parents and school matter? Protective factors for adolescent substance use

Protective factors may promote successful development by neutralizing the effects of negative risk factors. This paper is focused on possible protective factors of adolescent substance in a sample of high school students (N = 881) in Szeged, Hungary. Data were collected in 2008. Self-administered questionnaires were applied that measured smoking, binge drinking, marijuana use and parental and school-related protective factors. Multiple regression analysis revealed that parental monitoring was a universal protective factor for adolescents. Acceptance and respect of parents' values may serve as a protection against binge drinking among adolescents. High academic achievement was a predictor of smoking and binge drinking, talking about problems with teachers and being happy with school were predictors of marijuana use. Future research is needed to clarify the altered role of parent–child relationship in adolescents' substance use.     

Good choices,great future: An applied theatre prevention program to reduce alcohol‐related risky behaviours during Schoolies

Introduction and Aims. The contextual and temporal factors of post‐school celebratory events (‘Schoolies’) place young people at elevated risk of excessive drinking compared with other social occasions. This study investigates the impact of an applied theatre prevention program ‘Choices’ in reducing the risk of drinking and other risk behaviours during Schoolies celebrations. Design and Methods. Choices was delivered in the last term of Year 12 across 28 North Queensland schools. A total of 352 school leavers (43.1% male, mean age = 17.14 years) completed a questionnaire at Whitsunday Schoolies, Queensland, Australia on 23–24 November 2010. Nearly 49% of respondents had attended Choices. The survey included measures of alcohol use, illicit drug use and associated problems during Schoolies and a month prior to Schoolies. Results. After controlling for gender and pre‐Schoolies drinking, school leavers who attended Choices were significantly less likely to report illicit drug use (OR = 0.51, P < 0.05) and problem behaviours (OR = 0.40, P < 0.01) than those who did not attend Choices. There was, however, no intervention effect in risky drinking (i.e. drank on 5 or more days, typical amount five or more standard drink and binge drank on 3 or more days) at Schoolies (OR = 0.92, P = 0.80). Discussion and Conclusions. Delivery of a youth‐specific applied theatre prevention program employing a harm minimisation framework may be effective in reducing high‐risk behaviours associated with alcohol consumption at celebratory events, even if young people expect to engage in excessive alcohol consumption.

Assessing the effect of patterns of cocaine and alcohol use on the risk of adverse acute cocaine intoxication

Introduction and Aims. Although, in the laboratory, most acute adverse effects of cocaine are dose‐dependent and alcohol potentiates some of these effects, there are few observational studies, and scarce awareness that the risk of acute cocaine intoxication (ACI) can increase as the amounts of cocaine and alcohol consumed increase. Our objectives were to assess if the risk of ACI increases with the level cocaine use, both in chronic and binge use; and also to determine whether it increases when a cocaine binge is combined with binge drinking or with regular excessive drinking. Design and Methods. Hypotheses were evaluated using logistic regression and case‐crossover analyses in a sample of 720 young regular cocaine users who did not regularly use heroin, recruited at drug scenes in 2004–2006. All data on ACI, predictor and confounding variables were obtained through a computer‐assisted personal interview. Results. The annual prevalence of ACI was 21%. In the last year 10.3% of the participants reported cocaine binges (≥0.5 g in 4 h). ACI risk increased considerably in the 4 h following a cocaine binge (odds ratio = 34.6; 95% confidence interval 11.5–170.8). Also, it increased with increases in the average level of cocaine used over a long period and when users regularly drank excessively. Finally, the results suggest that the high risk of ACI associated with cocaine binge may increase even more when combined with binge drinking. Discussion and Conclusions. Awareness of the dose‐dependent effect of cocaine on ACI risk, as well as the possible synergistic effect of alcohol, ought to be incorporated into preventive and care strategies.[Santos S, Brugal MT, Barrio G, Castellano Y, Domingo‐Salvany A, Espelt A, Bravo MJ, de la Fuente L, the ITINERE Project Group.

Motives for drinking alcohol and eating palatable foods: An evaluation of shared mechanisms and associations with drinking and binge eating

BackgroundYoung adulthood is a high-risk period for heavy drinking and binge eating, both of which can impact weight and lead to obesity. Examining motives for drinking alcohol and eating palatable foods may facilitate a more integrated understanding of these behaviors during the college years. The current study tested whether shared or distinct (i.e., behavior-specific) motivational mechanisms may explain the occurrence of reward-driven drinking and eating in young adults.MethodsA sample of college freshmen (N = 103) stratified by sex, race/ethnicity, and heavy drinking status were selected to participate. Participants completed questionnaires measuring alcohol use, eating behavior, and motives assessed by the Drinking Motives Questionnaire-Revised and Palatable Eating Motives Scale. Confirmatory factor analysis (CFA) tested whether drinking and eating motives were better represented as single latent motives, or two behavior-specific motives. Structural equation modeling (SEM) was used to test the association between motivational factors and behaviors.ResultsBehavior-specific CFA models demonstrated stronger model fit and higher factor loadings than single motive models. SEM models indicated that eating to cope with negative emotions, to enhance positive experiences, to obtain social reinforcement, and to conform with peers were significantly associated with binge eating (p values < .001). Enhancement and social drinking motives were significantly associated with number of weekly drinks (p values < .001).ConclusionsWhile motives for drinking alcohol and eating palatable foods may satisfy common goals, findings suggest motivational mechanisms may be behavior-specific. Enhancement and social motives may be important factors to target in prevention programs for both drinking and binge eating.     

Energy drinks and alcohol-related risk among young adults

Background: Energy drink consumption, with or without concurrent alcohol use, is common among young adults. This study sought to clarify risk for negative alcohol outcomes related to the timing of energy drink use. Methods: The authors interviewed a community sample of 481 young adults, aged 18–25, who drank alcohol in the last month. Past-30-day energy drink use was operationalized as no-use, use without concurrent alcohol, and concurrent use of energy drinks with alcohol (“within a couple of hours”). Negative alcohol outcomes included past-30-day binge drinking, past-30-day alcohol use disorder, and drinking-related consequences. Results: Just over half (50.5%) reported no use of energy drinks,18.3% reported using energy drinks without concurrent alcohol use, and 31.2% reported concurrent use of energy drinks and alcohol. Relative to those who reported concurrent use of energy drinks with alcohol, and controlling for background characteristics and frequency of alcohol consumption, those who didn't use energy drinks and those who used without concurrent alcohol use had significantly lower binge drinking, negative consequences, and rates of alcohol use disorder (P < .05 for all outcomes). There were no significant differences between the no-use and energy drink without concurrent alcohol groups on any alcohol-related measure (P > .10 for all outcomes). Conclusions: Concurrent energy drink and alcohol use is associated with increased risk for negative alcohol consequences in young adults. Clinicians providing care to young adults could consider asking patients about concurrent energy drink and alcohol use as a way to begin a conversation about risky alcohol consumption while addressing 2 substances commonly used by this population.     

Selection and Socialization Influences on Adolescent Alcohol Use: The Individual and Joint Contexts of Neighborhood Disadvantage and Population Density

Background: Neighborhood disadvantage (ND) and population density (PD) are two community characteristics contextualizing friends’ influence on adolescent alcohol use. However, these community characteristics are rarely examined for potential joint contributions, although it is possible that the way friends are selected or influence alcohol use are shaped by both ND and PD. In addition, prior studies examining ND or PD contexts on friend influence rarely discern between socialization and selection. Objectives: The current study examined how selection and socialization influences on adolescent alcohol use are shaped by unique and joint contexts of ND and PD. Methods: Adolescents from Waves I and II of the National Longitudinal Study of Adolescent and Adult Health (Add Health) were included in three models assessing friends’ socialization of alcohol us initiation and binge drinking, and selection of drinking friends. ND and PD were tested for mediation and moderation individually and jointly. Results: Results indicated that socialization of drinking initiation was stronger in high ND contexts, and that continued binge drinking was stronger in low ND contexts. PD indirectly influenced socialization of initiation and binge drinking maintenance via a negative association with number of drinking friends. PD and ND jointly influenced the association between initial binge drinking and next-year selection of drinking friends, such that selection was stronger within areas related to lower levels of drinking friends. Conclusions/Importance: Current results indicate that PD and ND shape friends’ influence on alcohol use in unique ways. These must be accounted for to better understand bidirectional effects of friend influence.     

What explains the decline in adolescent binge-drinking in New Zealand?

BackgroundBinge-drinking prevalence among New Zealand adolescents has declined sharply since 2001, as it has in many other high-income countries. Other adolescent risk behaviours (e.g. smoking, cannabis use and precocious sexual activity) have also declined, raising the possibility of common underlying drivers. This study investigates potential contributing factors – both factors that predict risk behaviours in general, and alcohol-specific factors – and the extent to which they account for the decline in binge drinking.MethodsThe study used nationally representative survey data collected in 2001 (N = 6513), 2007 (N = 5934) and 2012 (N = 5489). The outcome measure was prevalence of past month binge drinking (5+ drinks/session). Predictor variables included factors that predict risk behaviours in general (parental monitoring, family attachment, school attachment, having a part-time job, time spent hanging out with friends); alcohol-specific factors (parental alcohol use, adolescent attitude toward alcohol use); and attitude toward and current use of tobacco and cannabis. Likelihood of binge drinking was modelled for each survey year (ref=2001), adjusting for demographic factors. Predictors were added to this base model, with the degree of attenuation of the odds ratio for year indicating the extent to which the included predictor(s) accounted for the trend.ResultsCompared with 2001 the odds of binge-drinking in 2012 were 0.33. The strongest independent contributor to the decline was adolescent attitude toward alcohol use, followed by current cannabis use, then current tobacco use. Collectively, general factors in home, school and leisure settings did not significantly contribute to the downward trend in binge drinking.ConclusionDecreasing acceptability of alcohol use among adolescents was the most important identified contributor to adolescent binge-drinking decline. Drinking, smoking and cannabis use trends were empirically linked, yet the decline in binge drinking was not significantly explained by the included predictors common to risk behaviours in general.     

‘Off your Face(book)’: alcohol in online social identity construction and its relation to problem drinking in university students

Introduction and Aims. Alcohol is a key component of identity exploration for many young people, yet few studies have investigated identity construction in relation to problematic drinking. Increases in youth alcohol consumption have coincided with expanding use of communications technologies, particularly social networking sites (SNS), which have altered traditional conditions of identity construction. It has been found young people often engage with alcohol in the SNS environment by portraying themselves as binge drinkers. The current study applied an innovative approach to identity construction (the photographic essay) to provide insight into the portrayal of ‘alcohol‐identity’ on Facebook. Design and Methods. One hundred and fifty‐eight university students completed a range of alcohol measures before providing access for researchers to view their Facebook profiles to operationalise their alcohol‐identity according to autophotographic methodology. Results. Participants utilised a variety of photographic and textual material to present alcohol as a component of their identity on Facebook, with over half having selected an alcohol‐related profile image. Alcohol‐identity predicted alcohol consumption and problematic alcohol‐related behaviours as measured by questionnaires used to reliably identify alcohol‐related problems in university students. Almost 60% reported potentially problematic alcohol use according to the Alcohol Use Disorders Identification Test. Discussion and Conclusions. Findings suggest that portraying oneself as a drinker is considered by many young people to be a socially desirable component of identity in the SNS environment, perpetuating an online culture that normalises binge drinking. Ready‐made Facebook photo essays provide an alternate method of accessing problematic alcohol use, supplementing self‐report measures.[Ridout B, Campbell A, Ellis L. ‘Off your Face(book)’: Alcohol in online social identity construction and its relation to problem drinking in university students. Drug Alcohol Rev 2012;31:20–26]     

Drinking Patterns of College- and Non-College-Attending Young Adults: Is High-Intensity Drinking Only a College Phenomenon?

Background: Young adults report the heaviest drinking of any age group, and many are at risk for experiencing an alcohol use disorder. Most research investigating young adult drinking has focused on single indicators of use. Using multiple dimensions of consumption, such as federal guidelines for daily/weekly drinking and engagement in drinking at twice the binge threshold (“high-intensity drinking”) to characterize drinking behavior could illuminate drinking patterns linked with harms. Objectives: We used a person-centered approach to examine latent classes of drinkers from a national sample of young adults. Further, we compared classes on college status. Methods: We used 2012–2013 data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC)-III. We included past-year drinkers aged 18–22 years (n = 2213). Latent classes were estimated based on drinking frequency, daily/weekly drinking, frequency of heavy episodic drinking (4+/5+ drinks for women/men), frequency of high-intensity drinking (8+/10+ drinks), and intoxication frequency. Results: Five latent classes were identified: Occasional, Light Drinkers (30%), Regular Drinkers (6%), Infrequent Drinkers with Occasional Binging (10%), Frequent Drinkers with Occasional Binging (22%), and High-Intensity Drinkers (32%). Although membership in the two riskiest classes were more common among college-attenders, odds of being a High-Intensity Drinker relative to the second riskiest class was not significantly different for college- and non-college-attending young adults. Conclusions/Importance: As high-intensity drinking does not appear to be a drinking pattern unique to college-attenders and non-college-attenders are less likely to mature out of heavy drinking patterns, intervention efforts are needed for this at-risk age group.     

Alcohol Use in Emerging Adulthood: Can Moffitt's Developmental Theory Help Us Understand Binge Drinking Among College Students?

ABSTRACT

It is well-known that college students are at an increased risk for alcohol use and binge drinking compared to their same-age peers who are not in college. We use Moffitt's developmental taxonomy, specifically, her discussion of adolescence-limited offending, to contextualize this finding regarding this minor form of deviance. We also incorporate Arnett's notion of emerging adulthood to argue that the maturity gap, as described by Moffitt, can extend beyond adolescence. The current research used data from Wave III of the National Longitudinal Study of Adolescent Health (N = 4,264). We examined differences in sample characteristics between respondents who were currently enrolled in college full-time and those who were not. We also estimated several logistic regression models to determine how full-time college status and two measures of maturity were correlated with weekly binge drinking. We found that respondents who were full-time college students had an increased risk for binge drinking and were also less mature than their peers. Further analyses indicated that full-time college students were at an increased risk for binge drinking because they lacked maturity and the lack of adult roles that characterize the college years gives students more freedom to binge drink. These results supported both Moffitt's explanation of adolescence-limited offending and Arnett's notion of emerging adults.
