Performance of Alcohol and Safer Sex Change Rulers Compared With Readiness to Change Questionnaires.

As part of a larger intervention study, the authors hypothesized that change rulers created for alcohol and safer sex would be equivalent to longer questionnaires. Ninety-six male college students completed rulers and questionnaires for assessing behavior change readiness. Participants' scores on the rulers significantly correlated with their scores on the questionnaires (r = .77 for alcohol; r = .77 for safer sex). In both domains, the rulers outperformed the questionnaires in predicting behavioral intentions, suggesting that the rulers had at least comparable concurrent criterion validity. This finding is the first of its kind in the safe sex literature and suggests that quick assessments of readiness to change are possible. Because the rulers are a continuous measure, the results are consistent with the idea that the change process is continuous rather than a series of discrete stages.

Sitting at the virtual poker table: A prospective epidemiological study of actual Internet poker gambling behavior

Internet gambling is a potential object of addictive behavior and consequently an important concern for public health. Epidemiological analyses of Internet gambling are necessary to determine the extent of public health threat. This paper reports the results of the first prospective epidemiological study of actual Internet poker gambling behavior. Participants were 3445 Internet gambling service subscribers who enrolled during February 2005. Data include two years of recorded poker outcomes (i.e., chips bought and sold) for each poker session played. Among our sample, we identified two subgroups of poker players. Approximately 95% of the sample bought a median of €12 worth of chips at each of two poker sessions per week during a median duration from first to last bet of six months. A smaller subgroup (i.e., 5%) of most involved poker players bought a median of €89 worth of chip at each of 10 sessions per week during a median duration from first to last bet of 18 months. In addition to level differences, we report the differences in patterns of behavior observed between these two subgroups. The analyses presented in this paper suggest that the majority of Internet poker players moderated their behavior based on their wins and losses. A minority of most involved players did not show such moderation. These results have important implications for both gambling-and addiction-related research.     

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.

Live interactive group-specific normative feedback reduces misperceptions and drinking in college students: A randomized cluster trial.

This research evaluated the efficacy of a live and interactive group-specific normative feedback intervention designed to correct misperceptions of alcohol-related group norms and subsequently reduce drinking behavior. Campus organizations (N = 20) containing 1,162 college students were randomly assigned to intervention or assessment-only control conditions. Participants in the intervention condition attended an intervention during their organization's regular standing meeting. Data were gathered in vivo using computerized handheld keypads into which participants entered personal responses to a series of alcohol-related questions assessing perceptions of normative group behavior as well as actual individual behavior. These data were then immediately presented in graphical form to illustrate discrepancies between perceived and actual behavioral group norms. Results indicated that compared with the control group, the intervention group reduced drinking behavior and misperceptions of group norms at 1-month and 2-month follow-ups. Changes in perceived norms mediated the reductions in drinking. Results demonstrate the effectiveness of a novel, technologically advanced, group-based, brief alcohol intervention that can be implemented with entire groups at relatively low cost.

Measuring alcohol-related protective behavioral strategies among college students: Further examination of the Protective Behavioral Strategies Scale.

Heavy drinking among college students has been recognized as a public health problem on American college campuses (e.g., R. Hingson, T. Heeren, M. Winter, & H. Wechsler, 2005). Recently, protective behavioral strategies, or cognitive-behavioral strategies that can be implemented when using alcohol to reduce consumption and resulting negative consequences, have been shown to be associated with less alcohol use and fewer alcohol-related problems (e.g., S. L. Benton et al., 2004; M. P. Martens et al., 2005). The purpose of the present study was to conduct additional psychometric work on a measure designed to assess the use of such strategies: the Protective Behavioral Strategies Scale (PBSS; M. P. Martens et al., 2005). Data were collected on 505 undergraduate students from 2 universities who reported having consumed alcohol at least once in the past 30 days. Results of a confirmatory factor analysis supported the hypothesized 3-factor version of the PBSS, and scores on each subscale were correlated in the expected direction with both alcohol use and alcohol-related problems. Thus, the PBSS appears to be reliable and valid for use among college student drinkers. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Group identification as a moderator of the relationship between perceived social norms and alcohol consumption.

Previous research has shown that social norms are among the strongest predictors of college student drinking. Among college students, perceiving that others drink more heavily than themselves has been strongly and consistently associated with heavier drinking. Research has also shown that the more specifically others are defined, the stronger the association is with one's own drinking. In the current research, we evaluated whether group identification as defined by feeling closer to specific groups moderates the associations between perceived drinking norms in the group and one's own drinking. Participants included 3,752 (61% female) students who completed online assessments of their perceived drinking norms for 4 groups of students on their campus and identification with each group and participants' own drinking behavior. Results indicated that greater identification with same-sex students, same-race students, and same-Greek-status students was associated with stronger relationships between perceived drinking norms in the specific groups and own drinking.

Gambling problem symptom patterns and stability across individual and timeframe.

Few studies investigate gambling problems at the symptom level; even fewer investigate how symptom patterns change throughout the course of a gambling disorder. The current study utilized the National Epidemiological Survey on Alcohol and Related Conditions (NESARC; Grant et al., 2004) to investigate how the specific symptoms of disordered gambling relate to its severity and course. Results demonstrated that symptom patterns and stability changed as the number of symptoms endorsed increased. Symptom patterns varied considerably from prior to past year (PPY) to past year (PY) timeframes. Certain symptoms were more stable than others and held predictive value as markers of emerging pathological gambling (PG). In particular, gambling to escape problems was one of the most stable symptoms and also predictive of progression to PG; reliance on others to support gambling was predictive of progression to PG among participants at-risk for PG. The differential diagnostic value of various reported symptoms, as well as their lack of stability, has implications for both researchers and clinicians.

Laying the Foundation for Quantifying Regional Exposure to Social Phenomena: Considering the Case of Legalized Gambling as a Public Health Toxin.

Exposure and adaptation models provide competing perspectives of the environmental influence on the development of addictive disorders. Exposure theory suggests that the presence of environmental toxins (e.g., casinos) increases the likelihood of related disease (e.g., gambling-related disorders). Adaptation theory proposes that new environmental toxins initially increase adverse reactions; subsequently, symptoms diminish as individuals adapt to such toxins and acquire resistance. The authors describe a new public health regional exposure model (REM) that provides a tool to gather empirical evidence in support of either model. This article demonstrates how the strategic REM, modified to examine gambling exposure, uses standardized indices of exposure to social phenomena at the regional level to quantify social constructs.

What men want: The role of reflective opposite-sex normative preferences in alcohol use among college women.

Misperceptions of peer drinking norms have been found to be strongly associated with individual drinking behavior, especially for proximal reference groups such as same-sex friends. Less studied are the effects of perceived preferences from the opposite sex on alcohol use; that is, the behaviors an individual believes the opposite sex prefers from them. Research suggests that these perceived “reflective” normative preferences may be particularly salient among college women, who may drink in pursuit of intimate relationships and positive attention from male peers. Heterosexual undergraduate students from two universities participated in this project. Females answered questions regarding the amount of alcohol they believe a typical male would like his female friends, dates, or romantic partners to drink. Males answered the same questions, stating their actual preferences. Results showed that females overestimate the amount of alcohol males want their female friends, dating partners, and sexual partners to drink, and that this misperception was associated with their drinking behavior, even after controlling for perceived same-sex norms. These results suggest that reflective normative feedback may offer a powerful new tool for female-targeted interventions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
