Volunteerism, Alcohol Beliefs, and First-Year College Students' Drinking Behaviors: Implications for Prevention.

First-year students of traditional college age often drink irresponsibly, especially if they believe that alcohol use is integral to the college experience. Individuals who subscribe to this view embrace their transitional status, recognize that they have relatively few role obligations, and thus regard the college years as the timeframe for drinking. Volunteerism, which places additional constraints on students' behaviors by facilitating their integration into mature adult society and increasing social responsibility, may be an avenue for reducing levels of alcohol consumption among this subgroup. Numerous studies have found an inverse relationship between involvement in service and levels of alcohol consumption among college undergraduates. Data from a prospective survey administered to a cohort of first-year students of traditional college age at the beginning, and again at the end of the fall semester, was used to assess the relationship between volunteerism, alcohol beliefs, and drinking behavior (n = 423). Zero inflated negative binomial regressions indicated that alcohol beliefs moderated the effects of participation in volunteer/service activities on the frequency of alcohol use and heavy drinking. In particular, there was a strong negative relationship between volunteerism and heavy drinking among first-year students who believed that the use of alcohol was integral to the college experience. This suggests that engaging first-year students with permissive alcohol beliefs in service activities is a way to curb their drinking early, by the end of the first college semester, before it becomes a more long-term pattern.

The effects of public self-consciousness and embarrassability on college student drinking: evidence in support of a protective self-presentational model.

In this article we examine the effects of public self-consciousness (PSC) and a cross-situational reactivity to embarrassing encounters (EMB) on college students' levels of alcohol consumption by levels of perceived peer drinking. The analysis of self-report data from two undergraduate samples (n = 118 and n = 195) yielded virtually identical results and suggests that PSC and EMB affect alcohol use primarily among students with friends who drink heavily. Among these individuals, our findings are consistent with a protective self-presentational model. While PSC increased levels of alcohol consumption among students who believed drinking to be prevalent within their social circle if they were low in EMB, a susceptibility to embarrassment in response to the transgressions of self and others counteracted this tendency.

Beliefs about alcohol and the college experience, locus of self, and college undergraduates' drinking patterns.

The purpose of this study is to assess the extent to which locus of self (institutional versus impulse), measured using the Twenty Statements Test (TST), moderates the relationship between beliefs about alcohol and the college experience (BACE) and alcohol use among college undergraduates. Although the majority of our respondents listed more idiosyncratic personal characteristics and preferences than consensual social roles in response to the TST, the number of students classified as institutionals was notably higher than what has been reported within the literature. In opposition to our hypothesis that BACE would affect levels of alcohol consumption primarily among these individuals, our results indicated that the perception that alcohol use is integral to the college experience had a relatively minimal effect on drinking among respondents who defined themselves in terms of institutional roles. Moreover, multiple social roles themselves appeared to reduce the effects of BACE on levels of alcohol consumption. More impulse-oriented personal characteristics and preferences did not exhibit this moderating influence. Thus, our findings suggest that role occupation may be more important than locus of self in shaping students' susceptibility to beliefs about drinking and college life.

Effects of metalloproteinase inhibition in a murine model of renal ischemia-reperfusion injury.

Ischemia-reperfusion injury (IRI) is a leading cause of acute tubular necrosis (ATN) and delayed graft function in transplanted organs. Up-regulation of matrix metalloproteinases (MMPs) propagates the microinflammatory response that drives IRI. This study sought to determine the specific effects of Marimastat (Vernalis, BB-2516), a broad spectrum MMP and TNF-alpha-converting enzyme inhibitor, on IRI-induced ATN. Mice were pretreated with Marimastat or methylcellulose vehicle for 4 d before surgery. Renal pedicles were bilaterally occluded for 30 min and allowed to reperfuse for 24 h. Baseline creatinine levels were consistent between experimental groups; however, post-IRI creatinine levels were 4-fold higher in control mice (p < 0.0001). The mean difference between the post-IRI histology grades of Marimastat-treated and control kidneys was 1.57 (p = 0.003), demonstrating more severe damage to control kidneys. Post-IRI mean (+/-SEM) MMP-2 activity rose from baseline levels in control mice (3.62 +/- 0.99); however, pretreated mice presented only a slight increase in mean MMP-2 activity (1.57 +/- 0.72) (p < 0.001). In conclusion, these data demonstrate that MMP inhibition is associated with a reduction of IRI in a murine model.

Alcohol abuse as a rite of passage: the effect of beliefs about alcohol and the college experience on undergraduates' drinking behaviors.

Qualitative studies of alcohol's ritual influences indicate that college undergraduates who drink heavily tend to view alcohol use as integral to the student role and feel entitled to drink irresponsibly. Our analyses, based on a standardized measure of these beliefs administered to approximately 300 students, confirmed these findings. Among our sample, beliefs about alcohol and the college experience had an effect on levels of alcohol consumption similar in magnitude to that of other variables commonly associated with a risk for heavy drinking. Moreover, the alcohol beliefs index moderated the effects of three risk factors--gender, high school drinking, and friends' use of alcohol--on respondents' drinking behaviors. These findings are discussed within the context of the anthropological literature on liminality and rites of passage and with regard to strategies for intervention that address the structural roots of the widespread abuse of alcohol on college campuses.

Reactivity to conspicuousness and alcohol use among college students: the moderating effect of alcohol expectancies.

The analysis of self-report data from 147 college undergraduates suggested that alcohol expectancies moderate the effect of a dispositional susceptibility to embarrassment elicited by undesired conspicuousness [center-of-attention-induced embarrassability (CAE)] on drinking behavior. Individuals unlikely to experience embarrassment when they engage in behaviors that make them stand out in a crowd, a common occurrence when one drinks to excess, drank heavily if they expected alcohol to make them more assertive socially. Students with similar beliefs about the effects of alcohol on social interaction who were high in CAE consumed substantially less alcohol than the latter individuals. Their overall levels of drinking were more comparable to those of the low-expectancy participants, suggesting that the disdain for conspicuousness characteristic of people with a susceptibility to CAE may counteract the desire for social disinhibition that often motivates alcohol consumption.
