Objective: College men's alcohol consumption is positively associated with sexual aggression perpetration, yet men's drinking does not typically predict later sexual assault after accounting for risk factors, such as impersonal sexuality. In the present study, we tested an indirect effects model whereby college men's impersonal sex orientation and heavy episodic drinking (HED) were hypothesized to contribute to sexual aggression perpetration via more frequent attendance at drinking venues (parties, bars)., Method: Freshman males (N = 1,043) were recruited to participate in a five-semester study. Key measures included the Sociosexuality Index as a measure of impersonal sex attitudes and behaviors, frequency of HED, and frequency of attending drinking venues (parties, bars). The dichotomous outcome measure was based on the Sexual Strategies Survey, a measure of tactics used to convince a female partner to have sex. Structural equation modeling was used to examine whether sociosexuality attitudes, sociosexuality behaviors, and HED (all measured at Wave 1) would have direct and indirect effects on use of Wave 5 sexual aggression tactics, through effects on Wave 3 venue attendance., Results: The model supported the hypothesized indirect effects of sociosexuality and HED via men's subsequent drinking venue attendance and was preferred over alternative models., Conclusions: College men who more frequently attended drinking "hot spots" were more likely to perpetrate subsequent sexual aggression, supporting a growing body of evidence on the importance of drinking venues in college sexual assault. Findings also help to explicate the mechanism underlying the robust role of impersonal sex orientation in sexual aggression.

Objective: The current longitudinal study was designed to consider the time-varying effects of men's heavy episodic drinking (HED) and drinking setting attendance on college sexual assault perpetration., Method: Freshman men (N = 992) were recruited in their first semester and completed online measures at the end of their first five semesters. Using multilevel models, we examined whether men with higher frequency HED (or party or bar attendance) were more likely to perpetrate sexual assault (between-person, Level 2 effect) and whether sexual assault perpetration was more likely in semesters in which HED (or party or bar attendance) was higher than each individual's average (within-person, Level 1 effect)., Results: The between-person effect of HED on sexual assault was not significant after accounting for the between-person effects of antisocial behavior, impersonal sex orientation, and low self-control. The within-person effect of HED on sexual assault perpetration was not significant. However, models substituting frequency of party attendance or bar attendance revealed both between- and within-person effects. The odds of sexual assault were increased for men with higher bar and party attendance than the sample as a whole, and in semesters in which party or bar attendance was higher than their own average. Supplemental analyses suggested that these drinking setting effects were explained by hookups, with sexual assault perpetration more likely in semesters in which the number of hookups exceeded one's own average., Conclusions: Findings point toward the importance of drinking contexts, rather than drinking per se, as predictors of college men's sexual assault perpetration.

Objective: Despite showing reductions in college student drinking, interventions have shown some inconsistency in their ability to successfully decrease consequences. With the goal of improving prevention efforts, the purpose of this study was to examine the role of consequence-specific constructs, in addition to drinking, that influence students' experiences with alcohol-related problems. The study examined how drinking and protective behaviors mediated the relationships between students' willingness to experience consequences, intentions to avoid them, and four categories of alcohol-related problems (physiological, social, sexual, and academic)., Method: First-year college student drinkers (n = 2,024) at a large northeastern university completed surveys during the fall and spring of their freshman year., Results: As expected, different patterns of associations emerged for physiological and nonphysiological consequences. When physiological consequences (e.g., hangover, vomiting) were examined, drinking significantly mediated the effect of willingness on the consequences. Drinking-specific protective behaviors indirectly influenced consequences through drinking behaviors whereas general protective behaviors did not. When nonphysiological (e.g., social, sexual, academic) consequences were examined, drinking and general protective behaviors emerged as significant mediators of the effects of willingness and intentions on the consequences, whereas drinking-specific protective behaviors did not., Conclusions: The results suggest that prevention efforts (e.g., personalized feedback) could be tailored to address specific types of protective behaviors as well as specific types of consequences frequently experienced by college students.

Objective: The first semester of college has been associated with increased drinking and sexual risk. However, it remains unclear why some drinking occasions result in experiencing negative sexual consequences whereas others do not. The current study used a diary-based approach to assess the event-level effect of alcohol use and previous adult/adolescent sexual victimization (PSV) on experiencing negative sex-related consequences in first-year college women., Method: Participants (N=120) provided repeated measures of weekend drinking and sex-related consequences on the Friday and Saturday nights of six different weekends over the course of their first semester, resulting in 12 measured drinking occasions. A multilevel model was used to assess both between- and within-person effects of alcohol use and between-person effects of PSV on the likelihood of experiencing negative alcohol-related sexual consequences., Results: Findings revealed an important within-person association, such that every drink consumed above one's mean was associated with a 13% increase in the likelihood of experiencing negative consequences. In addition, PSV had a significant main effect on experiencing negative sex-related consequences. Individuals with PSV experienced nearly 2.5 times more sexual consequences than individuals without PSV., Conclusions: These results yield important implications for prevention, particularly with respect to limiting "above average" alcohol consumption among women with a history of sexual victimization.

Objective: Research indicates that alcohol consumption by college students fluctuates across the semester, with consumption changing because of social events and calendar holidays. In addition, some research indicates that Thursday alcohol consumption is a function of Friday course schedule. Students with courses after 10 a.m. or not at all on Friday are more likely to consume alcohol on Thursday nights. Furthermore, college women are increasingly consuming alcohol at higher levels and comprise a larger portion of college students in comparison with their male counterparts. The current study was aimed at examining patterns of Thursday night alcohol consumption and academic load among female college students., Method: College students (N = 383, 100% female) participated in a 10-week paper- and web-based survey on alcohol consumption. After completion of the study, academic records of the participants were retrieved for objective measures of academic load., Results: Patterns of Thursday alcohol consumption relate to timing and difficulty of the first course on Friday. However, patterns of Thursday alcohol consumption were not related to other aspects of academic load (e.g., number of academic credits, fall semester grade-point average, cumulative grade-point average, other Friday courses)., Conclusions: It seems that female students who are more likely to consume alcohol on Thursday night have made academic scheduling decisions to allow for this experience. These decisions seem to not adversely affect their grade-point average. Findings suggest that changes to the academic calendar to curb alcohol consumption warrant further investigation.

Objective: Studies show that emerging adults who do not obtain postsecondary education are at greater risk for developing alcohol use disorders later in life relative to their college-attending peers. Research examining constructs amenable to change within this population is necessary to inform intervention efforts. Thus, the current study aimed to identify psychosocial correlates of risky alcohol use for noncollege emerging adults. A secondary goal was to examine whether gender moderated the relationships between the psychosocial constructs and alcohol use., Method: Participants were a nationally representative sample of noncollege emerging adults (18-22 years old) who reported using alcohol in the past year, recruited through an established Internet panel (N = 209; 125 women). A path model was used to examine the relationship between theoretically derived constructs (expectancies, attitudes, normative beliefs) and risky (peak) drinking. A second model examined a multigroup solution to assess moderating effects of gender., Results: The full-sample model revealed significant associations between attitudes toward drinking and risky drinking. The model assessing gender differences revealed association between normative beliefs and drinking for women but not men, whereas attitudes were significantly associated with risky drinking for both men and women., Conclusions: Findings highlight the importance of attitudes and, for women, descriptive norms in the etiology of risky drinking among noncollege emerging adults, which emphasizes their potential utility in the development and adaptation of interventions for this at-risk population.

Objective: Previous research identified a high-risk subgroup of students who experience high levels of multiple and repeated alcohol-related consequences (MRC group). Although they consist of 20% of the population and account for nearly 50% of the consequences, the MRC group has not been the focus of etiological or prevention research. The present study identified pre-college profiles of psychosocial and behavioral characteristics and examined the association between these profiles and membership in the MRC group., Method: The sample consisted of 370 first-year college students (57% female) recruited in the summer before college. Participants reported on typical drinking, alcohol-related risky and protective drinking behaviors, alcohol beliefs, descriptive and injunctive norms, and alcohol-related consequences at three time points over 15 months., Results: Latent profile analysis identified four baseline student profiles: extreme-consequence drinkers, high-risk drinkers, protective drinkers, and nondrinkers. Logistic regression revealed that, when the high-risk drinkers were used as the reference group, both the protective drinkers and the nondrinkers were significantly less likely to be members of the MRC group, whereas the extreme-consequence drinkers were at increased odds of being in the MRC group, even after first-year drinking was controlled for. Student profiles and previously identified parental profiles both had unique main effects on MRC group membership, but there was no significant interaction between parental and student profiles., Conclusions: Findings suggest ways that brief interventions can be tailored for students and parents in relation to the MRC group.

Objective: Among emerging adults, those who do not attain postsecondary education are at highest risk for experiencing longterm problems related to alcohol use, including alcohol dependence. The purpose of the current study was to identify latent classes of alcohol users among non-college-attending youth and examine correlates of class membership., Method: Screening criteria were used to select emerging adults between ages 18 and 22 years with no postsecondary education (N = 264) from a prerecruited probability-based Web panel. Latent class analysis (LCA) was used to identify common patterns of alcohol use. Grouping variables and demographic variables were added to the LCA model, and rates of alcohol-related consequences across the LCA classes were compared., Results: Four classes of drinking patterns were identified: (a) current nondrinkers (34%), (b) weekend light drinkers (38%), (c) weekend risky drinkers (23%), and (d) daily drinkers (5%). Class membership was associated with early onset of alcohol use (age 14 or younger), marital status, employment status, and urban residency (area populated by 50,000 or more people). The number of latent classes did not differ across sex and legal drinking age status, although proportions of subjects within classes varied by age. Weekend risky drinkers were most likely to report sickness and feelings of guilt because of drinking, whereas daily drinkers were most likely to report getting into fights, driving a car after drinking, and missing work., Conclusions: Similar to college samples of emerging adults, most of this noncollege sample belonged to latent classes defined by rare or moderate alcohol use. Nevertheless, nearly a quarter of the sample reported high-risk drinking behaviors, and a small number reported drinking alcohol on a daily basis. Both of these classes were at elevated risk for experiencing a number of alcohol-related consequences.

Objective: The study evaluated the timing and dosage of a parent-based intervention to minimize alcohol consumption for students with varying drinking histories., Method: First-year students (N = 1,900) completed Web assessments during the summer before college (baseline) and two follow-ups (fall of first and second years). Students were randomized to one of four conditions (pre-college matriculation [PCM], pre-college matriculation plus boosters [PCM+B], after college matriculation [ACM], and control conditions). Seven indicators of drinking (drink in past month, been drunk in past month, weekday [Sunday to Wednesday] drinking, Thursday drinking, weekend [Friday, Saturday] drinking, heavy episodic drinking in past 2 weeks, and peak blood alcohol concentration <.08) were used in a latent transition analysis (LTA) to examine a stage-sequential model of drinking. LTA models with dummy-coded intervention variables were used to examine the effects of the intervention conditions on changes in drinking patterns., Results: Results indicated that four patterns of drinking were present at all waves: (a) nondrinkers, (b) weekend light drinkers, (c) weekend heavy episodic drinkers, and (d) heavy drinkers. Results indicated that the PCM condition was most effective at influencing baseline heavy drinkers' transition out of this pattern to lower risk patterns at first follow-up, whereas the ACM condition was not effective at preventing drinking escalation for baseline nondrinkers at first follow-up. No decay of effects was observed at long-term follow-up for the PCM condition. Finally, the results also indicated that increased dosage of the parental intervention was not significantly associated with either reduction or escalation of use., Conclusions: The results underscore the value of pre-college parental interventions and targeted efforts to reduce high-risk drinking among college students.

Objective: Although studies have demonstrated that an adolescent's parents and friends both influence adolescent substance use, it is not known whether the parenting experienced by one's friends also affects one's own use. Drawing on conceptions of shared parenting and the tenets of coercion theory, we investigated the extent to which three domains of parenting behaviors (parental knowledge, inductive reasoning, and consistent discipline) influenced the alcohol, cigarette, and marijuana use of not only their own adolescent children but also of members of their adolescents' friendship groups., Method: Analyses of friendship nominations within each of two successive ninth-grade cohorts in 27 Iowa and Pennsylvania schools (N = 7,439 students, 53.6% female) were used to identify 897 friendship groups. Hierarchical logistic regression models were used to examine prospective associations between 9th-grade friendship group-level parenting behaviors and adolescent self-reported alcohol, cigarette, and marijuana use in 10th grade., Results: Adolescent substance use in 10th grade was significantly related to parenting behaviors of friends' parents, after controlling for adolescents' reports of their own substance use and their own parents' behaviors at the 9th grade level. These associations were particularly strong for parents' knowledge about their children and use of inconsistent discipline strategies. Significant interaction effects indicated that these relationships were strongest when adolescents received positive parenting at home. Some, but not all, of the main effects of friends' parents' parenting became nonsignificant after friends' substance use in ninth grade was included in the model., Conclusions: The findings suggest that the parenting style in adolescents' friends' homes plays an important role in determining adolescent substance use. Implications of the joint contribution of parents and peers for prevention and intervention are discussed.
