Effects of alcohol, expectancies, and partner type on condom use in college males: event-level analyses

HIV information and behavioral skills moderate the effects of relationship type and substance use on HIV risk behaviors among African American youth

The HIV/AIDS epidemic is disproportionately impacting young African Americans. Efforts to understand and address risk factors for unprotected sex in this population are critical in improving prevention efforts. Situational risk factors, such as relationship type and substance use before sex, are in need of further study. This study explored how established cognitive predictors of risky sexual behavior moderated the association between situational factors and unprotected sex among low-income, African American adolescents. The largest main effect on the number of unprotected sex acts was classifying the relationship as serious (event rate ratio=10.18); other significant main effects were alcohol use before sex, participant age, behavioral skills, and level of motivation. HIV information moderated the effect of partner age difference, motivation moderated the effects of partner age difference and drug use before sex, and behavioral skills moderated the effects of alcohol and drug use before sex. This novel, partnership-level approach provides insight into the complex interactions of situational and cognitive factors in sexual risk taking.

Substance use, sexual intercourse, and condom nonuse among depressed adolescents and young adults

PURPOSE

To examine daily- and event-level associations of substance use with occurrence of sex and condom nonuse among depressed youth.

METHODS

Depressed, sexually active outpatients aged 15-22 years reported alcohol use, marijuana use, and sex on a personal digital assistant for 2 weeks. If they reported sex, participants indicated partner type and condom use. Data were analyzed for participants who reported both substance use and sex events (N = 39) using generalized estimating equations. Daily-level models compared the likelihood of sex and of condom nonuse between days on which participants did or did not use substances. Event-level models examined the likelihood of sex in the 2, 6, and 12 hours after substance use and the likelihood of condom nonuse if substances were used in the preceding 2, 6, and 12 hours.

RESULTS

Participants reported 307 sex events (180 unprotected) and 391 substance use events on 572 days. Substance use was associated with increased odds of sex on the same day, but not after adjusting for weekend. Depressed youth were less likely to have sex within 2 hours after substance use and more likely to have sex within 12 hours after marijuana use. There was no main effect of substance use on condom nonuse; however, there was a significant interaction such that on weekdays, condom nonuse was less likely when substances were used within 6 hours before sex.

CONCLUSIONS

The findings from this small, predominantly female sample suggest that contextual factors, not intoxication, influence associations of substance use with sexual behavior in depressed youth.

Changes in women's condom use over the first year of college

Most college students are sexually active, engage in serially monogamous relationships, and use condoms inconsistently. Little is known about how condom use changes during college, and even less about variables predicting changes in use. Latent growth modeling (LGM) was used to examine changes in condom use during the first year of college among 279 women (mean age = 18.0; 74% White), who provided monthly reports on condom use frequency. At study entry, participants also reported on theoretically suggested risk and protective factors. Predictors of changes in use were examined after controlling for use of alternative contraception and partner type. LGM showed that women decreased their condom use during the first year of college. Levels of condom use were initially lower among women with strong alcohol-sexual risk expectancies, women with more previous sexual partners, women who did not smoke marijuana, and African American women. Decreases in condom use were greater among women with lower grade point averages, women from lower socioeconomic status families, and women who engaged in binge drinking. Reductions in condom use may place women at greater risk of unplanned pregnancy and sexually transmitted infections. Identification of factors associated with decreases in condom use will enable targeted educational and intervention efforts.

Young adults and casual sex: the relevance of college drinking settings

This study investigated the relevance of college drinking settings on the likelihood of students having sexual intercourse with a stranger. A random sample of 7,414 undergraduates at 14 public California universities responded to questions regarding frequency of attendance at six different setting types since the beginning of the semester (e.g., Greek, residence-hall parties, and bars or restaurants), drinking behavior, and sexual activity. Multi-level modeling examined the association between each setting type and the occurrence of alcohol-related sexual intercourse with a stranger. Findings indicated strong, positive associations between frequency of attendance at Greek parties, residence-hall parties, off-campus parties, and the occurrence of alcohol-related sex with a stranger. Frequency of attending the six settings and proportion of times drunk at the settings were also positively associated with alcohol-related sex with a stranger. Efforts aimed at preventing outcomes associated with casual sex (e.g., pregnancy, sexually transmitted infections, or mental health) should target specific drinking settings where students might be at high risk for risky alcohol use and unsafe sex behaviors.

"This would be better drunk": alcohol expectancies become more positive while drinking in the college social environment

The current study examined whether drinking and/or presence in the college social environment led to augmented positive alcohol expectancies among college students (N=225). Participants were approached during popular drinking nights as they exited events at which alcohol was consumed or in front of their residence as they returned home. Participants completed a brief questionnaire that included an assessment of demographics, breath alcohol concentration (BrAC), and positive expectancies. Within 48 h of baseline assessment, participants received via email a follow-up survey that re-assessed positive expectancies while sober. Positive sexual expectancies were more strongly endorsed while drinking in the college social environment for both males and females, while males also reported heightened liquid courage expectancies. In addition, positive expectancies were more strongly endorsed at higher doses of alcohol for males but not females. These findings suggest that interventions which seek to prevent alcohol abuse by targeting alcohol expectancies may wish to challenge positive expectancies in naturalistic college social settings.

Juvenile Delinquency and Teenage Pregnancy

The authors examined ecological risk factors associated with teen pregnancy with a sample of 1,190 court-involved female juvenile offenders between 11 and 18 years of age. Data were obtained from five Midwestern juvenile county courts using a recently developed youth risk assessment instrument called the global risk assessment device (GRAD). In line with past research on teen pregnancy, the authors found that young African American female offenders were three times more likely to have ever been pregnant than their European American counterparts. Factorial multivariate analysis of variance (MANOVA) procedures were conducted to identify the ecological risk domains that differentiated groups of female juvenile offenders in the sample of this study, based on their pregnancy history and racial background. The findings of this study suggest that female offenders who had experienced a pregnancy had significantly higher levels of health-related risks as compared to their counterparts who had never been pregnant. Furthermore, regardless of their pregnancy history, White female offenders reported significantly greater involvement in substance abuse behaviors as compared to Blacks. Taken together, these findings underscore the need to utilize comprehensive risk assessments when designing integrated intervention programs that are tailored to the unique needs of young female offenders who are at risk for early pregnancies.

Alcohol and STI risk: evidence from a New Zealand longitudinal birth cohort

BACKGROUND

The present study examined the associations between involvement with alcohol and risks of sexually transmitted infection (STI) during adolescence and early adulthood.

METHODS

A 30-year prospective longitudinal study of the health, development, and adjustment of a birth cohort of 1265 New Zealand-born individuals. Measures included repeated assessments of frequency of alcohol use and number of symptoms of alcohol disorder from ages 15 to 30 and rates of STI from ages 14 to 30. Conditional fixed effects regression models augmented by observed time-dynamic covariate factors were used to control for non-observed confounding in the associations between alcohol and STI risk.

RESULTS

There were clear and consistent trends for increasing involvement with alcohol to be linked with increased risk of STI diagnoses. Adjustment of the associations for sources of non-observed confounding and time-dynamic covariate factors reduced the magnitude of these associations, but they remained statistically significant (p < .05).

CONCLUSIONS

The results of the current study support the notion of the existence of a causal pathway in which increasing levels of alcohol use and symptoms of alcohol abuse/dependence led to increased risks of STI exposure. There was little evidence to suggest that the links between alcohol involvement and STI risk could be fully explained by an underlying predisposing factor that increased the risks of both alcohol involvement and STI.

Self-regulation as a protective factor against risky drinking and sexual behavior

Prior research suggests that high dispositional self-regulation leads to decreased levels of risky drinking and sexual behavior in adolescence and the early years of college. Self-regulation may be especially important when individuals have easy access to alcohol and freedom to pursue sexual opportunities. In the current 1-year longitudinal study, we followed a sample of N = 1,136 college students who had recently reached the legal age to purchase alcohol and enter bars and clubs to test whether self-regulation protected against heavy episodic drinking, alcohol-related problems, and unprotected sex. We tested main effects of self-regulation and interactions among self-regulation and established risk factors (e.g., sensation seeking) on risky drinking and sexual behavior. High self-regulation inversely predicted heavy episodic drinking, alcohol-related problems, and unprotected sex, even when taking into account gender and risk factors. Moreover, in predicting unprotected sex, we found three-way interactions among self-regulation, sensation seeking, and heavy episodic drinking. Self-regulation buffered against risk associated with heavy drinking but only among those low in sensation seeking. The protective effects of self-regulation for risky drinking and sexual behavior make it a promising target for intervention, with the caveat that self-regulation may be less protective among those who are more drawn to socially and emotionally rewarding stimuli.

The influence of alcohol expectancies and intoxication on men's aggressive unprotected sexual intentions

An experiment tested the pathways through which alcohol expectancies and intoxication influenced men's self-reported sexual aggression intentions during an unprotected sexual encounter. After a questionnaire session, male social drinkers (N = 124) were randomly assigned to either an alcohol condition (target peak BAC = .08%) or a control condition. Upon completion of beverage consumption, participants read a description of a sexual encounter in which the female partner refused to have unprotected sexual intercourse. Participants then rated their emotional state, their intentions to have unprotected sex with the unwilling partner, and their postincident perceptions of the encounter. Structural equation modeling indicated that intoxicated men reported feeling stronger sexual aggression congruent emotions/motivations such as arousal and anger; however, this effect was moderated by alcohol expectancies. Intoxicated participants with stronger alcohol-aggression expectancies reported greater sexual aggression congruent emotions/motivations than did intoxicated participants with weaker alcohol-aggression expectancies. For sober participants, alcohol-aggression expectancies did not influence emotions/motivations. In turn, stronger sexual assault congruent emotions/motivations predicted greater sexual aggression intentions. Men with greater sexual aggression intentions were less likely to label the situation as a sexual assault and reported less concern about their intended actions. These findings underscore the relevance of both alcohol expectancies and alcohol intoxication to sexual aggression perpetration and highlight the importance of including information about alcohol's influence on both emotional and cognitive responses in sexual aggression prevention work.

Alcohol and risky sexual behavior among heavy drinking college students

Multiple event-level methodology was used to examine the relation between risky sexual behavior and alcohol use among sexually active, heavy drinking college students (N = 221). Using a structured timeline follow-back interview, participants reported their sexual, alcohol, and drug use behaviors over a 3-month period. Over 2,700 vaginal or anal sexual events were reported from 177 participants. Overall, condom use was not associated with heavy or non-heavy alcohol consumption among those reporting both sexual events concurrent with heavy drinking and when no alcohol was consumed. Results from multilevel regression analyses revealed a more complex pattern. Among women, but not men, less condom use was associated with steady versus casual sexual partners, but partner type interacted with alcohol consumption such that less condom use occurred when heavy drinking preceded sex with steady partners. At the event-level, alcohol consumption among heavy drinking college students leads to risky sexual behavior but the relation differs by gender and partner type.

Application of the social action theory to understand factors associated with risky sexual behavior among individuals in residential substance abuse treatment

Risky sexual behavior (RSB) is a leading cause of HIV/AIDS, particularly among urban substance users. Using the social action theory, an integrative systems model of sociocognitive, motivational, and environmental influences, as a guiding framework, the current study examined (1) environmental influences, (2) psychopathology and affect, (3) HIV-related attitudes and knowledge, and (4) self-regulatory skills/deficits as factors associated with event-level condom use (CU) among a sample of 156 substance users residing at a residential substance abuse treatment center (M age = 41.85; SD = 8.59; 75% male). RSB was assessed using event-level measurement of CU given its advantages for improved accuracy of recall and ability for an examination of situational variables. A logistic regression predicting event-level CU indicated the significant contribution of partner type (environmental influences), less favorable attitudes towards condoms (HIV-related attitudes and knowledge), and higher levels of risk-taking propensity (self-regulatory skills/deficits) in predicting greater likelihood of not having used a condom at one's most recent sexual encounter. This study contributes to the literature examining HIV risk behaviors among substance users within a theory-driven model of risk.

"Hooking up" among college students: demographic and psychosocial correlates

This study investigated 832 college students' experiences with hooking up, a term that refers to a range of physically intimate behavior (e.g., passionate kissing, oral sex, and intercourse) that occurs outside of a committed relationship. Specifically, we examined how five demographic variables (sex, ethnicity, parental income, parental divorce, and religiosity) and six psychosocial factors (e.g., attachment styles, alcohol use, psychological well-being, attitudes about hooking up, and perceptions of the family environment) related to whether individuals had hooked up in the past year. Results showed that similar proportions of men and women had hooked up but students of color were less likely to hook up than Caucasian students. More alcohol use, more favorable attitudes toward hooking up, and higher parental income were associated with a higher likelihood of having hooked up at least once in the past year. Positive, ambivalent, and negative emotional reactions to the hooking up experience(s) were also examined. Women were less likely to report that hooking up was a positive emotional experience than men. Young adults who reported negative and ambivalent emotional reactions to hooking up also reported lower psychological well-being and less favorable attitudes toward hooking up as compared to students who reported a positive hooking up experience. Based on these findings, suggestions for psychoeducational programming are offered. Additionally, directions for future research are provided.

Psychological distress, substance use, and HIV/STI risk behaviors among youth

Psychological distress has been inconsistently associated with sexual risk behavior in youth, suggesting additional factors, such as substance use, may explain this relationship. The mediating or moderating role of substance use on the relationship between psychological distress and sexual risk behaviors was prospectively examined over the four high school years in a sample of urban youth (N = 850; 80% African American; 50% female). Growth curve modeling was used to estimate changes in sexual risk across adolescence and to test its association to psychological distress symptoms and frequency of substance use. Substance use was associated with psychological distress. Greater psychological distress was associated with increased sexual intercourse frequency, decreased condom use, and increased number of partners. Substance use fully mediated the relationship between psychological distress and intercourse frequency and condom use, and partially mediated the relationship between psychological distress and number of partners. We found no differences in mediation by sex or race/ethnicity and no evidence to support moderation of psychological distress and substance use on sexual risk. Findings suggest that psychological distress is associated with sexual risk because youth with greater psychological distress are also more likely to use substances. Practical implications for adolescent HIV/STI prevention are discussed.

Alcohol as a correlate of unprotected sexual behavior among people living with HIV/AIDS: review and meta-analysis

The present investigation attempted to quantify the relationship between alcohol consumption and unprotected sexual behavior among people living with HIV/AIDS (PLWHA). A comprehensive search of the literature was performed to identify key studies on alcohol and sexual risk behavior among PLWHA, and three separate meta-analyses were conducted to examine associations between unprotected sex and (1) any alcohol consumption, (2) problematic drinking, and (3) alcohol use in sexual contexts. Based on 27 relevant studies, meta-analyses demonstrated that any alcohol consumption (OR = 1.63, CI = 1.39-1.91), problematic drinking (OR = 1.69, CI = 1.45-1.97), and alcohol use in sexual contexts (OR = 1.98, CI = 1.63-2.39) were all found to be significantly associated with unprotected sex among PLWHA. Taken together, these results suggest that there is a significant link between PLWHA's use of alcohol and their engagement in high-risk sexual behavior. These findings have implications for the development of interventions to reduce HIV transmission risk behavior in this population.

Alcohol consumption and risk of incident human immunodeficiency virus infection: a meta-analysis

OBJECTIVE

To analyze the relationship between alcohol consumption and incident HIV infection.

METHODS

Articles were identified via electronic and hand searches. Inclusion criteria were: incident HIV infection, preceding alcohol consumption, and association relating the two. The DerSimonian and Laird random effects model was used. For studies with more than one estimate of a given type, estimates were combined using the inverse variance weighted method. Publication bias was assessed using Begg's and Egger's tests. Heterogeneity was assessed using Q and I (2) statistics.

RESULTS

Ten studies were included. Overall alcohol consumption (any of the three types identified) increased the risk of HIV (RR 1.98, 95% CI 1.59-2.47). Alcohol consumers were at 77% higher risk (RR 1.77, 95% CI 1.43-2.19). Those consuming alcohol prior to, or at the time of, sexual relations were at an 87% increased risk (RR 1.87, 95% CI 1.39-2.50). For binge drinkers, the risk was double that of non-binge drinkers (RR 2.20, 95% CI 1.29-3.74).

CONCLUSIONS

Alcohol consumption is associated with an increased risk of incident HIV infection. Additional research is required to further investigate a possible causal role.

Does drinking lead to sex? Daily alcohol-sex behaviors and expectancies among college students

A within-person multilevel approach was used to model the links between alcohol use and sexual behavior among first-year college students, using up to 14 days of data for each person with occasions (Level 1, N = 2879 days) nested within people (Level 2, N = 218 people; 51.4% male). Between-persons (Level 2) effects were gender, relationship status, person means of alcohol use, and alcohol-sex expectancies for sexual affect and sexual drive. Within-person (Level 1) effects were weekend days, number of drinks consumed, and the interaction between drinks consumed and alcohol-sex expectancies. Independent of average alcohol use, consuming more drinks on a given day was associated with a greater likelihood of oral sex and with experiencing more positive consequences of sex that day. Significant Alcohol Use x Alcohol-Sex Expectancies interactions were found for oral sex and total sex behaviors, indicating that individuals with more positive expectancies were more likely to have sex after drinking. The negative association between drinks and condom use was at a trend level of significance. Results support the potential for promoting sexual health by focusing on cross-behavior expectancies among late adolescents.

Toward prevention of alcohol exposed pregnancies: characteristics that relate to ineffective contraception and risky drinking

Alcohol-exposed pregnancy is a leading cause of preventable birth defects in the United States. This paper describes the motivational patterns that relate to risky drinking and ineffective contraception, two behaviors that can result in alcohol-exposed pregnancy. As part of an intervention study aimed at reducing alcohol-exposed pregnancy 124 women were recruited and reported demographic characteristics, readiness to change, stages of change, drinking, contraception, and sexual behavior history. Our results showed the following. Drinking: A significant positive correlation was found between the number of drinks consumed in 90 days and the Importance to reduce drinking (r = .23, p = .008). A significant negative correlation between number of drinks and confidence to reduce drinking (r = -.39, p = .000) was found as well. Significant differences were found in the total number of drinks consumed in 90 days between the five stages of change (F = (4,118), 3.12, p = .01). Women in Preparation reported drinking a significantly higher number of drinks than women in other stages of change. Contraception: There were significant negative correlations between ineffective contraception and Importance (r = -.38, p = .00), confidence (r = -.20, p = .02) and Readiness (r = -.43, p = .00) to use contraception effectively. Significant differences in contraception ineffectiveness were found for women in different stages of change (F = (4,115) 8.58, p = .000). Women in Precontemplation reported significantly higher levels of contraception ineffectiveness compared to women in other stages of change. Results show a clear relationship between higher alcohol consumption and higher levels of motivation to reduce drinking. In contrast, higher levels of ineffective contraception were related to lower levels of motivation to use contraception effectively. This suggests risky drinking may be better targeted with brief skills building interventions and ineffective contraception may require interventions that enhance problem awareness and motivation.

Alcohol consumption, drug use, and condom use among STD clinic patients

OBJECTIVE

Research on the association between substance use and sexual risk behavior has yielded a complex pattern of findings. Such inconsistent findings may reflect method variance, including factors such as gender of the participant, nature of the sexual event, partner characteristics, and type of substance used. The purpose of this study was to investigate the association between substance use and unprotected sex independently for alcohol, drugs, or combined substance use and to examine partner characteristics as a moderator of this association.

METHOD

Participants (N = 1,419; 48% women) were recruited from a publicly funded sexually transmitted disease clinic and were asked to complete an audio computer-assisted self-interview regarding their most recent sexual experience, including nature of the event, substance use, and partner characteristics.

RESULTS

Analyses showed that alcohol use was related to condom use when gender and partner type were considered; thus, for women, but not for men, partner type interacted with alcohol consumption such that condom use was less likely when alcohol consumption preceded sex with nonprimary partners (drinking was unrelated to condom use with primary partners). Subsequent analyses examining partner substance use showed that women, but not men, who reported both they and their nonprimary partners were drinking during sex were less likely to use a condom.

CONCLUSIONS

At the event level, alcohol consumption among sexually transmitted disease clinic patients is associated with condom use, but this association differs by gender and partner characteristics. Findings suggest the need to strengthen substance-use components in sexual risk reduction interventions for women and their partners.

An assessment of HIV/STI vulnerability and related sexual risk-taking in a nationally representative sample of young Croatian adults

Despite the recent increase in the number of HIV infections in Central and Eastern Europe, patterns of sexual behavior have not been extensively researched, particularly among young people. The aim of the present study was to provide a comprehensive assessment of HIV/AIDS-related vulnerability and sexual risk-taking among young adults in Croatia. Data were collected in 2005 using a nationally representative, multi-stage stratified probability sample (n = 1,093) of women and men aged 18-24 years. The focus in this article was on predictors of sexual risk-taking measured by a composite risky sexual behaviors scale. Using hierarchical regression models, we analyzed gendered effects of community, family, peer group, and individual level factors. For both men and women, peer pressure, sensation seeking, personal risk-assessment, behavioral intention, condom use at first sexual intercourse, and sexual victimization were significant predictors of sexual risk-taking behaviors. A number of predictors were gender-specific: sexual assertiveness and condom self-efficacy for women and parental monitoring, traditional morality, HIV knowledge, and talking about sex with partner for men. Documenting substantial prevalence of potentially risky sexual behaviors among young people in Croatia, the findings call for prevention and intervention efforts that should focus on individual capacity building for responsible sexual behavior.

An event-level analysis of condom use as a function of mood, alcohol use, and safer sex negotiations

Daily self-reports of condom-protected intercourse were analyzed as a function of emotional states, alcohol consumption, and safer sex negotiations in a sample of single, low-income Hispanic students. The sample included 15 women and 17 men who reported a minimum of four sexual episodes as well as inconsistent condom use over a 3-month self-reporting period. The analyses focused on 829 days out of 2,586 daily self-reports on which sexual intercourse was reported. Hierarchical linear modeling was used to predict condom-protected intercourse as a function of mood states, substance use, and safer sex negotiations. Safer sex negotiation was the strongest positive predictor of condom use. Contrary to expectation, unprotected intercourse was less likely to occur in episodes characterized by greater negative affect and more likely in episodes in which greater positive mood was reported. No main effect of alcohol consumption on safer sex was observed; however, an interaction between alcohol consumption and positive mood emerged, indicating that unprotected intercourse was most likely to occur when positive mood was combined with alcohol consumption. The results contradict the assumption that emotional distress predicts engagement in more risky sexual behavior and indicate that safer sex negotiations are likely to outweigh any effects of mood or alcohol consumption on subsequent condom use.

Factors associated with sexual risk behaviour among young people in Ukraine

We used data from a behavioural survey of Ukrainian men and women aged 14-24 to examine the relationship between nine potential risk factors and two HIV risk outcomes: non-use of condom at last sex, and multiple sexual partnerships. Younger age at first sex was positively associated with both health risk outcomes, and condom non-use at first sex was associated with subsequent non-use of condoms at last sex. There were regional differences in frequencies of both HIV risk behaviours. Compared with those who reported living in the place they were born, not living permanently at the current place of residence was associated with a fivefold increase in the odds of multiple partnership for women but not for men. Alcohol and drug use were associated with higher odds of multiple partnership and the effect was greater among women than among men. The data analysed are cross-sectional so cannot establish causality. More studies are needed to confirm these results and investigate causal relationships between the possible risk factors and the two health risk behaviours.

College students' perceptions about alcohol and consensual sexual behavior: alcohol leads to sex

The phenomenology of college students' conceptualization of the relations between alcohol and sex are surprisingly understudied. Undergraduates rank among the most-studied populations, yet extant research largely relies on quantitative methods, which are constrained in their ability to give participants a "voice." The current study used focus groups to investigate 14 male and 15 female undergraduates' conceptualizations of the relations between alcohol and consensual sex. Focus group themes indicated gendered and universal relations between alcohol and sex and positive and negative aspects of these relations. A robust relation between sex and alcohol was noted (men and women), and participants reported deliberately seeking out alcohol to indicate sexual willingness (women), reject sexual advances directly (women), and facilitate making sexual advances (men). Implications for educators are discussed.

Alcohol and HIV sexual risk behaviors among injection drug users

We analyzed data from 6341 injection drug users (IDUs) entering detoxification or methadone maintenance treatment in New York City between 1990 and 2004 to test the hypothesis that alcohol use and intoxication is associated with increased HIV sexual risk behaviors. Two types of associations were assessed: (1) a global association (i.e., the relationship between HIV sexual risk behaviors during the 6 months prior to the interview and at-risk drinking in that period, defined as more than 14 drinks per week for males or 7 drinks per week for females), and (2) an event-specific association (i.e., the relationship between HIV sexual risk behaviors during the most recent sex episode and alcohol intoxication during that episode). Sexual risk behaviors included multiple sex partners and engaging in unprotected sex. After adjusting for the effects of other variables, at-risk-drinkers were more likely to report multiple sex partners and engaging in unprotected sex with casual sex partners (both global associations). IDUs who reported both they and their casual partners were intoxicated during the most recent sex episode were more likely to engage in unprotected sex (an event-specific association). We also observed two significant interactions. Among IDUs who did not inject cocaine, moderate-drinkers were more likely to report multiple partners. Among self-reported HIV seropositive IDUs, when both primary partners were intoxicated during the most recent sex episode they were more likely to engage in unprotected sex. These observations indicate both global and event-specific associations of alcohol and HIV sexual-risk behaviors.

Alcohol use, partner type, and risky sexual behavior among college students: Findings from an event-level study

Alcohol use is prevalent among college students and may contribute to elevated rates of sexual risk taking. Using event-level data, the hypothesis that partner type would moderate the effect of alcohol consumption on condom use was tested. Sexually active college students (N=330; 67% female) reported on characteristics of their most recent sexual encounter, including partner type, alcohol use, and condom use, along with measures of sex-related alcohol expectancies, sensation seeking, and typical alcohol use. Unprotected vaginal sex (UVS) was reported by 39% of the sample and 32% reported alcohol use prior to sex. For the complete sample, UVS was just as likely for non-drinking events as for events involving alcohol use. However, for sexual encounters involving a non-steady partner, alcohol consumption was associated with an increase in UVS, whereas rates of UVS did not vary by drinking status for encounters involving a steady partner. These effects remained in analyses that controlled for sex-related alcohol expectancies, sensation seeking, and typical alcohol use. Findings confirm that the effects of alcohol vary according to the context in which it is used.

Liquid courage: alcohol fosters risky sexual decision-making in individuals with sexual fears

The interaction of sexual fear and acute alcohol intoxication on the likelihood of risky sexual behavior was explored. Participants (Ps; N = 115) completed a measure of sexual fears and were randomly assigned to no-, low-, or high-dose alcohol conditions. Ps then read an eroticized vignette, where they were the protagonist, and rated their likelihood of sex with a new partner when no condom was available. Controlling for gender and social desirability, compared to sober Ps, highly intoxicated Ps indicated that they were more likely to engage in risky sexual behaviors. Sexual fear was modestly negatively related to risky sex likelihood among sober or mildly intoxicated Ps but strongly positively related to risky sex likelihood among highly intoxicated Ps. Findings underscore the notion that alcohol affects different types of individuals differently and indicate that alcohol may foster sexual risk-taking, in part, by attenuating or counteracting fear or anxiety.
