Ethnic differences and the closing of the sex gap in alcohol use among college-bound students.

In this study, the authors used Web-based surveys to examine differences in alcohol use by sex and ethnicity and factors associated with these group differences among 2,241 college-bound students. A Sex x Ethnicity interaction indicated that the sex gap was much larger for Latino than for Caucasian students. Although peer influence was important for both Caucasian and Latino students, family influences were significant only for Latino youths. The sex differences in drinking among Latino youths were largely explained by the combination of same-sex family member and same-sex peer drinking through values about the acceptability of drinking behavior. Among Caucasians, perceptions of peer behavior exerted a stronger influence on drinking behavior than among Latinos. These results suggest that interventions targeting peer influence are likely to be most effective for Caucasian students. In contrast, for Latinos, particularly Latina women, family characteristics may be an important target for prevention.     

Risk drinking and contraception effectiveness among college women

Risk drinking, especially binge drinking, and unprotected sex may co-occur in college women and increase the risks of STI exposure and pregnancy, but the relationships among these behaviors are incompletely understood. A survey was administered to 2012 women of ages 18–24 enrolled in a public urban university. One-quarter of the college women (23%) drank eight or more drinks per week on average, and 63% binged in the past 90 days, with 64% meeting criteria for risk drinking. Nearly all sexually active women used some form of contraception (94%), but 18% used their method ineffectively and were potentially at risk for pregnancy. Forty-four percent were potentially at risk for STIs due to ineffective or absent condom usage. Ineffective contraception odds were increased by the use of barrier methods of contraception, reliance on a partner's decision to use contraception, and risk drinking, but were decreased by the use of barrier with hormonal contraception, being White, and later age to initiate contraception. In contrast, ineffective condom use was increased by reliance on a partner's decision to use condoms, the use of condoms for STI prevention only, and by risk drinking. Thirteen percent of university women were risk drinkers and using ineffective contraception, and 31% were risk drinkers and failing to use condoms consistently. Risk drinking is related to ineffective contraception and condom use. Colleges should promote effective contraception and condom use for STI prevention and consider coordinating their programs to reduce drinking with programs for reproductive health. Emphasizing the use of condoms for both pregnancy prevention and STI prevention may maximize women's interest in using them.     

Ergopsychometry. New methods in experimental psychodiagnosis of pathologic stress reactions

Ergopsychometry--testing under physiological and/or psychological stress--has proved to be increasingly successful in recent years. In particular in sports psychology, in which only physiological stress had been considered, have experimental results been successfully implemented into practice. The fact that some subjects appear unchanged or even yield better results under stress than under stress-free conditions applies not only to physiological stress, but also holds true for psychological stress. These results have consequences for the experimental psychodiagnoses of pathological stress reactions, e.g., with alcoholics or psychosomatic patients. Proceeding from the above hypothesis we investigated 20 gamma-alcoholics (so-called relieve drinkers) and 20 psychosomatic inpatients under stress-free as well as under stress conditions, according to the ergopsychometric approach. The control group consisted of 23 subjects matched with respect to age, sex, and profession. We used a test battery to assess concentration, memory, and choice-reaction as well as the subjective state of activation, stress-coping-mechanisms, and self-concepts. Essentially, the validity of ergopsychometric designs was confirmed by our results. In accordance with our expectations, 27.5% of the experimental group showed increasing efficiency scores, compared to 56.5% in the control group. Possible explanations for the findings can be derived from the assessment of subjective activity, but not from of the personality questionnaires.     

Risk,religiosity, and emerging adulthood: description of Christian,Jewish, and Muslim university students at entering the freshman year

American students transitioning to university are at an increased risk for behaviours such as binge drinking, depression and suicidality. Despite the proliferation of prevention and intervention programs, rates remain high. Although religiosity is known to confer a protective effect in this population, it remains largely untapped as a resource because, among other reasons, it is poorly understood, poses ethical challenges, and exposes areas of distrust between the religious and medical establishments. This report describes the findings of a survey that examined possible factors explaining the relationship between religiosity, risky behaviours and emotional extremes in students as they transitioned into their first year of university. This study accounted for the religious diversity of the US by surveying Christian, Jewish, Muslim and religiously unaffiliated students. Findings indicated that religiosity was consistently and negatively correlated to risky behaviours across all faith groups. Interestingly, unique patterns in levels of religiosity emerged among the various faith groups. Similarly, patterns of engagement in risky behaviours demonstrated variation among religious groups. Our findings add to the body of evidence that suggests university-based professionals take into consideration student religiosity when creating prevention intervention programs for students.     

A randomized trial of a brief primary-care-based intervention for reducing at-risk drinking practices.

This randomized trial evaluated an intervention for reducing at-risk drinking practices in a sample of 307 patients. Eligible drinking patterns included chronic drinking (> or = 2 drinks per day in the past month), binge drinking (> or = 5 drinks per occasion at least twice in the past month), and drinking and driving (driving after > 2 drinks in the past month). Members of the intervention group received a message from their physician during their regularly scheduled visit, a self-help manual, written personalized feedback, and up to 3 telephone counseling calls. Dropout was significantly higher in the intervention than control group.     

A comparison of alcoholics whose drinking is totally uncontrolled and those whose drinking is mainly controlled

The analysis of drinking patterns of 77 married male alcoholics for the period of 12 months immediately following their intake into a treatment trial suggested the importance of a variable which has been neglected in the literature on alcohol dependence. Although only 3 had returned to a pattern of drinking which was, by their own and by their wives' accounts, totally controlled, there were wide individual differences amongst the remainder in the uniformity with which drinking was uncontrolled. Two extreme groups were identified: in 22 cases patients and their wives were agreed that drinking had been totally uncontrolled; in 14 cases patients and wives were agreed that drinking had been mainly controlled. There were no differences between these two groups in the amount of abstinence reported but there were major differences in other respects. Mainly controlled drinkers were more likely to think that they had no drinking problem or that their problem was of very recent origin, reported significantly fewer symptoms, were much less likely to be institutionalized during the 12 month period, were less likely to think of themselves as alcoholics and were less likely to express a preference for abstinence as a target. The hypothesis is suggested that this drinking pattern variable may serve as a differential predictor of successful outcome following abstinence-oriented or controlled drinking-oriented treatment.     

An Examination of the Mediational Effects of Cognitive and Attitudinal Factors of a Parent Intervention to Reduce College Drinking

As part of a parent intervention to reduce heavy-drinking, college freshmen were assessed for their attitudes toward drinking and reasonable alternatives to drinking on the weekends, as well as cognitive variables underlying attitudinal variables. Intervention parents received a handbook the summer prior to college entrance with information about college drinking and best practices for parent-teen communication. Results revealed that the association between intervention condition and drinking outcomes was mediated by attitudes favorable to drinking and reasonable alternatives to drinking, as well as beliefs about alcohol related behavior. This parent program was shown to be efficacious for changing high-risk drinking in college. Findings are discussed regarding the further development of college drinking prevention programs involving parents.     

Changes in heavy drinking over the third decade of life as a function of collegiate fraternity and sorority involvement: a prospective, multilevel analysis.

Although affiliation with a fraternity or sorority is an important risk factor for heavy drinking, recent research indicates that this risk may be limited to the college years. Random coefficient growth modeling was used to track changes in patterns of heavy drinking over the course of 11 years as a function of gender and collegiate Greek involvement (N=318). Overall, greater cumulative exposure to the Greek system led to increased heavy drinking during the college years, particularly among men. Shortly after leaving college, heavy drinking levels dropped markedly and remained low through approximately age 30. Inclusion of peer alcohol use norms in the model reduced the influence of Greek involvement. Implications for models of heavy drinking and health risks are discussed.     

21st birthday celebratory drinking: evaluation of a personalized normative feedback card intervention.

This research was designed to evaluate a personalized normative feedback birthday card intervention aimed at reducing normative perceptions, alcohol consumption, and negative consequences associated with 21st birthday celebrations among college students (N=281; 59.15% women). Students were randomly assigned to receive or not receive a birthday card about 1 week prior to their 21st birthday. Approximately 1 week following their birthday, students were asked to complete a brief survey concerning their birthday celebration activities. Findings indicated that the birthday card intervention was not successful at reducing drinking or consequences; however, the card did reduce normative misperceptions. Additional findings indicated that many students experienced negative consequences, such as passing out or driving after consuming alcohol. Combined, these findings suggest that prevention is needed for drinking associated with turning 21. However, prevention efforts should consist of more than a birthday card.     

Disrupted patterns of consummatory behavior in rats with fornix transections

The feeding and drinking behavior was examined in male rats with fornix transections and sham-operated control rats. Total food and water consumption was recorded but supplemented by a pattern analysis of feeding and drinking behavior. The behavior of the rats was continuously monitored during four hour morning and afternoon sessions under ad lib access and during a two hour session following adaptation to a restricted access feeding schedule. Rats with fornix transections were more active and exhibited increased frequencies of rearing, eating and drinking. The increased meal frequency in rats with fornix transections was accompanied by decreased meal durations and a reduction in the length of intermeal intervals. Total food and water consumption was unaffected by fornix transection as were the duration of sleep bouts and the frequencies of grooming, sleeping and carrying shavings. Fornix transections also reduced food carrying and food hoarding but only under conditions of restricted food access. The results suggest that fornix transection does not alter major homeostatic regulatory mechanisms nor does it alter the components of feeding and drinking behavior. Fornix transection alters, instead, the organization of microregulatory feeding and drinking patterns.     

A randomized motivational enhancement prevention group reduces drinking and alcohol consequences in first-year college women.

Alcohol consumption among college students has become an increasing problem that requires attention from college administrators, staff, and researchers. Despite the physiological differences between men and women, college women are drinking at increasingly risky rates, placing them at increased risk for negative consequences. The current study tested a group motivational enhancement approach to the prevention of heavy drinking among 1st-year college women. Using a randomized design, the authors assigned participants either to a group that received a single-session motivational enhancement intervention to reduce risky drinking that focused partly on women's specific reasons for drinking (n = 126) or to an assessment-only control group (n = 94). Results indicated that, relative to the control group participants, intervention participants drank fewer drinks per week, drank fewer drinks at peak consumption events, and had fewer alcohol-related consequences over a 10-week follow-up. Further, the intervention, which targeted women's reasons for drinking, was more effective in reducing consumption for participants with high social and enhancement motivations for drinking.     

Modeling Cyclical Patterns in Daily College Drinking Data with Many Zeroes

Daily college drinking data often have highly skewed distributions with many zeroes and a rising and falling pattern of use across the week. Alcohol researchers have typically relied on statistical models with dummy variables for either the weekend or all days of the week to handle weekly patterns of use. However, weekend versus weekday categorizations may be too simplistic and saturated dummy variable models too unwieldy, particularly when covariates of weekly patterns are included. In the present study we evaluate the feasibility of cyclical (sine and cosine) covariates in a multilevel hurdle count model for evaluating daily college alcohol use data. Results showed that the cyclical parameterization provided a more parsimonious approach than multiple dummy variables. The number of drinks when drinking had a smoothly rising and falling pattern that was reasonably approximated by cyclical terms, but a saturated set of dummy variables was a better model for the probability of any drinking. Combining cyclical terms and multilevel hurdle models is a useful addition to the data analyst toolkit when modeling longitudinal drinking with high zero counts. However, drinking patterns were not perfectly sinusoidal in the current application, highlighting the need to consider multiple models and carefully evaluate model fit.     

Measuring drinking patterns among college students.

Alcohol use among college students is of interest to clinicians and researchers. The results of such studies depend on the quality and nature of the measures used. The literature includes a wide variety of operational definitions of drinking patterns, making difficult comparisons across studies. For 109 men and 83 women attending college this paper provides data on the Drinking Practices Questionnaire, a self-report measure of drinking patterns designed specifically for use with college students. The three subscales, Negative Affect, Positive Expectancies, and Negative Consequences, have good internal consistency reliabilities, and scores correlate significantly with measures of problems associated with alcohol use. Appropriate uses of the measure are discussed.     

Localization of receptors for the dipsogenic action of angiotensin II in the subfornical organ of rat.

The proposal of the subfornical organ (SFO) as a site of receptors for drinking induced by angiotensin II (AII) was investigated with several mutually confirmatory experiments. Intracranial injections of physiological doses of AII elicited drinking if and only if applied directly to the SFO (Experiment I). Ablation of the SFO selectively (Experiment 2) and permanently (Experiment 4) eliminated drinking elicited by physiological doses of intravenously infused AII. Animals in which SFO had been ablated responded normally to cellular dehydration but reduced responding to the extracellular thirsts of beta-adrenergic activation and hyperoncotic colloid dialysis (Experiment 3). Infusion of saralasin, an AII antagonist, directly into the SFO selectively and reversibly antagonized intravenous AII drinking (Experiment 5). The hypothesis that the SFO contains dipsogenic receptors for circulating AII is strongly supported.     

SCHEDULE-INDUCED DRINKING: ELICITATION,ANTICIPATION, OR BEHAVIORAL INTERACTION?

We carried out five experiments with rats on fixed-time schedules in order to define the relation between drinking and individual food-pellet presentations. In Experiment 1, unsignaled extra food occurred at the end of occasional fixed intervals, and we compared subsequent drinking patterns with drinking before the extra food presentation. In Experiment 2 we presented signaled and unsignaled extra food and measured elicited and anticipatory drinking patterns. In Experiment 3, we observed the persistence of modified drinking patterns when several consecutive intervals ended with extra pellets. In Experiments 4 and 5, we varied the magnitude of food delivery across (rather than within) sessions to replicate published findings. Results show that schedule-induced drinking is neither elicited by food presentations nor induced by stimuli associated with a high food rate. All subjects seemed to follow a simple rule: during any stimulus signaling an increase in the local probability of food delivery within a session, engage in food-related behavior to the exclusion of drinking. Schedule-induced drinking appears to be the result of dynamic interactions among food-related behavior, drinking, and other motivated behavior, rather than a direct effect of the contingencies of food reinforcement.     

Activity patterns in rats (Rattus norvegicus) as a function of the cost of access to four resources

Patterns of eating, drinking, wheel running, and nesting were recorded in 2 experiments in which rats (Rattus norvegicus) lived in a laboratory environment that provided food, water, a running wheel, and a nest box. Access to each resource was contingent on the completion of a fixed ratio of bar presses and once earned remained available until the resource was not used for 10 consecutive min. In all cases an increase in the access price of a resource produced a decrease in the frequency with which the resource was accessed. This reduction in bout frequency was countered by an increase in bout size, which was compensatory for eating and nearly so for drinking, but which was only partially compensatory for wheel running. Nest bout size did not change significantly as nest price increased. The bout patterns of these 4 activities changed independently of one another, and the probabilities of behavioral transitions did not indicate strong links between any pairs of activities.     

Relationships between drinking and type of practice among U.S. female and male attorneys.

The author investigated the relationship between drinking and type of practice among U.S. attorneys. Participants were attorneys from 2 large midwestern cities, chosen through stratified random sampling from bar-association membership lists. Type of law practice was related to whether the participants drank in business-related situations but not to the frequency or the quantity of consumption. The participants in solo, corporate, or government practices were more likely than were those in private group practices to report no business-related drinking in the past 30 days. Female and male attorneys in similar practices reported similar abstention rates and quantities of consumption in business situations, suggesting that occupational norms were strongly salient for both genders. Criminal trial work was related to drinking only for the women. Results are discussed in terms of the influence of occupational culture on drinking.     

Association of solitary binge drinking and suicidal behavior among emerging adult college students

[Correction Notice: An Erratum for this article was reported in Vol 26(3) of Psychology of Addictive Behaviors (see record 2012-13892-001). In the article, there is an error in the introductory paragraph. The number of students who had seriously considered attempting suicide in the Barrios, Everett, Simon, & Brener (2000) study should have been reported as 11.4%, not 1.4%. Additionally, in the Participants section, data for the study were collected from March 2009 to September 2010, not March 2009 to January 2010 as reported.] Emerging adult college students who binge drink in solitary contexts (i.e., while alone) experience greater depression and suicidal ideation than do students who only binge drink in social contexts, suggesting that they may be at greater risk for suicidal behavior. This study examined the association of a previous suicide attempt, one of the best predictors of future suicide attempts and suicide, and severity of recent suicidal ideation with drinking in solitary and social contexts. Participants were binge drinking, emerging adult (18- to 25-year-old) college students (N = 182) drawn from two studies of college drinkers. A logistic regression analysis revealed that both suicide attempt history and severity of suicidal ideation were significantly associated with a greater likelihood of being a solitary binge drinker as opposed to only a social binge drinker. Students with a previous suicide attempt were nearly four times more likely to be solitary binge drinkers. Multiple regression analyses revealed that suicide attempt history was significantly associated with greater frequency and quantity of drinking in solitary, but not social contexts. Suicidal ideation was significantly associated with drinks per solitary drinking day, but not frequency of solitary drinking once suicide attempt history was accounted for. Given the associations found between solitary binge drinking and a history of suicide attempts, as well as greater severity of recent suicidal ideation, it appears that these students are in need of suicide prevention efforts, including treatment efforts aimed at reducing binge drinking.

Heavy episodic drinking: determining the predictive utility of five or more drinks.

Although the heavy episodic drinking (HED) measure of 5+ drinks (sometimes 4+ for women) is used extensively, there is no empirical basis for the designation of 5 drinks as the threshold (vs. another threshold that may perform equally). The present study sought to determine the threshold for HED that maximally predicts proximal and distal adverse-drinking-related outcomes. Participants included 115 young adults (57% female; 96% Caucasian) who partook in an 8-week Internet survey that assessed daily drinking as well as next-day hangover; 10 months later, adverse outcomes (problem drinking, alcohol-related problems, maximum number of drinks, and drug use) were surveyed. Thresholds were computed, with a range from 1+ drinks to 15+ drinks, and outcomes were predicted from each threshold. Findings for hangover measures showed relatively good convergence across multiple indicators, with greatest prediction occurring at a threshold of 10+ drinks per occasion. Different thresholds were observed for long-term outcomes, with higher thresholds indicative of outcomes with greater severity. Although alternatives to HED, such as subjective effects and blood alcohol concentration, can indicate risky drinking, a threshold measure of HED may have advantages in terms of prevention and of intervention efforts.     

Mood and alcohol consumption: an experience sampling test of the self-medication hypothesis

In this investigation the authors applied the experience sampling method to prospectively test the self-medication hypothesis. In vivo reports gathered in the context of daily life demonstrated that nervousness was the only negative mood state to predict increases in alcohol consumption later in the course of the day. Further examination of this within-person relationship demonstrated that men were more likely to consume alcohol when nervous than were women, but this association was unrelated to family history of alcoholism, problem drinking patterns, or trait anxiety and depression. Consistent with the self-medication hypothesis, cross-sectional analyses also confirmed that alcohol consumption was generally associated with lower levels of nervousness; this effect varied by several demographic and clinical variables. These findings are discussed in terms of the diversity of reasons for alcohol consumption and their potential for explaining problem drinking.
