Although alcohol consumption and sexual risk taking are associated, not everyone who drinks alcohol engages in risky sexual behavior. The purposes of the present study were to identify patterns of alcohol use behaviors and alcohol expectancies among women who are non-problem drinkers and to examine how these patterns are associated with indices of sexual risk.

Data from 758 non-problem drinking women who have sex with men and were not in committed relationships were analyzed using latent profile analysis to determine patterns of alcohol use and alcohol-related expectancies.

Of the four patterns observed, three classes had similar alcohol-related expectancies but differed with respect to drinking behavior (moderate drinking, regular heavy episodes, and frequent heavy episodes), and the fourth class consisted of moderate drinkers with low expectancies (low expectancies). Results revealed that those in the frequent heavy episodes class had the greatest number of sexual partners in the past year and drank the most alcohol before having sex compared with the other women. Both the regular and frequent heavy episodes classes reported greater likelihood of having unprotected sex in the future, more positive beliefs about casual sex, and greater subjective intoxication before having sex than women in the moderate drinking or low expectancies classes. Women in the low expectancies class reported less positive beliefs about condoms than those in the moderate drinking and regular heavy episodes classes.

Results suggest that different patterns of expectancies and drinking behaviors are associated with different indices of sexual risk taking and highlight the importance of individually tailored programs for prevention of sexually transmitted infections.

    ABSTRACT: To characterize patterns of alcohol use in a sample of Argentinean female college students according to personality traits and alcohol expectancies. Data from 298 female college students (M age = 18.27 years; SD = 1.37 years) from the city of Cordoba, Argentina were analysed using multinomial regression. Three drinking categories were identified, abstainers, moderate drinkers and regular drinkers with heavy episodic drinking, and these were differentiated by three personality traits [extraversion, disinhibition (DIS) and experience seeking (ES)] and three alcohol expectancies dimensions (sociability, risk/aggression and negative mood). Regular drinkers with heavy episodic drinking and moderate drinkers had, compared to abstainers, higher scores in extroversion and alcohol expectancies for social facilitation, and lower scores in alcohol expectancies for risk and aggression. Regular drinkers with heavy episodic drinking exhibited, compared to moderate drinkers, higher scores in ES, DIS, extroversion, alcohol expectancies for social facilitation and negative mood alcohol expectancies; as well as lower scores in risk and aggression alcohol expectancies. College women in Argentina with problematic alcohol drinking can be distinguished from those drinking moderately. © The Author 2015. Medical Council on Alcohol and Oxford University Press.

    • "Future research may examine this. The SRAEs of African American women attending an STI clinic may result in high-risk sex and also in unwanted=forced=coerced sex and suggests the importance of developing integrated alcohol–sexual risk reduction interventions for high-risk women (Sales et al., 2012; Stappenbeck et al., 2013). First, we recommend that such interventions increase self-awareness and selfmonitoring by helping women identify their SRAEs. "

    ABSTRACT: African American women are disproportionately affected by human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and sexually transmitted infections (STIs). Alcohol use is a significant risk factor for HIV/STI acquisition. Sex-related alcohol expectancies (SRAEs) may partially account for alcohol-related risky sexual behaviors. Using qualitative interviews we explored the link between alcohol use and risky sex among 20 African American women attending an STI clinic who had consumed four or more alcoholic drinks per drinking day (binge drinking) and/or reported vaginal or anal sex while under the influence of alcohol. Four SRAEs emerged, which we named drink for sexual desire, drink for sexual power, drink for sexual excuse, and drink for anal sex. While the desire SRAE has been documented, this study identified three additional SRAEs not currently assessed by expectancy questionnaires. These SRAEs may contribute to high-risk sex when under the influence of alcohol and suggests the importance of developing integrated alcohol-sexual risk reduction interventions for high-risk women.

    ABSTRACT: Prior person-centered research has consistently identified a subgroup of highly religious participants that uses significantly less alcohol when compared to the other subgroups. The construct of religious motivation is absent from existing examinations of the nuanced combinations of religiousness dimensions within persons, and alcohol expectancy valuations have yet to be included as outcome variables. Variable-centered approaches have found religious motivation and alcohol expectancy valuations to play a protective role against individuals' hazardous alcohol use. The current study examined latent religiousness profiles and hazardous alcohol use in a large, multisite sample of ethnically diverse college students. The sample consisted of 7412 college students aged 18-25 (M age = 19.77, SD age = 1.61; 75 % female; 61 % European American). Three latent profiles were derived from measures of religious involvement, salience, and religious motivations: Quest-Intrinsic Religiousness (highest levels of salience, involvement, and quest and intrinsic motivations; lowest level of extrinsic motivation), Moderate Religiousness (intermediate levels of salience, involvement, and motivations) and Extrinsic Religiousness (lowest levels of salience, involvement, and quest and intrinsic motivations; highest level of extrinsic motivation). The Quest-Intrinsic Religiousness profile scored significantly lower on hazardous alcohol use, positive expectancy outcomes, positive expectancy valuations, and negative expectancy valuations, and significantly higher on negative expectancy outcomes, compared to the other two profiles. The Extrinsic and Moderate Religiousness profiles did not differ significantly on positive expectancy outcomes, negative expectancy outcomes, negative expectancy valuations, or hazardous alcohol use. The results advance existing research by demonstrating that the protective influence of religiousness on college students' hazardous alcohol use may involve high levels on both quest and intrinsic religious motivation.
