The pleasure or reinforcement value of high-risk sex may be an important influence on success in risk reduction efforts. Seronegative gay and bisexual men (N?=?297) completed measures assessing their unprotected and safer sex practices, as well as measures of cognitive and skill factors and a measure assessing the subjective reinforcement value of unprotected anal intercourse. Regression analyses showed that the reinforcement value of unprotected anal intercourse accounted for variance in predicting levels of condom use above that that could be accounted for by factors such as knowledge, behavior change intentions, perceived vulnerability, condom attitudes, and sexual communication skills. Only reinforcement value of unprotected sex and substance use significantly predicted how frequently participants engaged in high-risk sex. Increased attention to the valence of sexual reinforcers will improve HIV risk reduction models and enhance AIDS prevention efforts.

Little is known about behavioral and psychological mechanisms that may explain relationships between posttraumatic stress and sexual risks. As rates of HIV infection among African American women remain significantly higher than for other female subgroups, research on sexual risk among African American women is needed. The present study examines the relationships of posttraumatic stress symptoms as measured by the Posttraumatic Stress Disorder Checklist-Civilian Version with sexual risk behaviors, sexual sensation-seeking, and sexual compulsivity in 30 undergraduate African American women with any reported history of sexual intercourse. Higher posttraumatic stress symptoms were associated with more sexual partners, greater frequency of vaginal sex without a condom, and endorsement of sex while under the influence of a substance. Posttraumatic stress symptoms were negatively correlated with perceived sexual control, but were not significantly correlated with sexual compulsivity or sensation-seeking. Perceived sexual control was negatively associated with frequency of unprotected sex and sex under the influence. The preliminary evidence from this small sample suggests sexual control may mediate the relationship of the posttraumatic stress symptoms with unprotected sex. These results are generally consistent with previous findings suggesting posttraumatic stress is associated with sexual risk. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Objective: Health behavior theories posit that health-relevant attitudes, beliefs, and behavioral skills drive subsequent actions people take to protect themselves from health threats. Within the realm of HIV-related sexual risk behavior, much of the research in support of this notion is cross-sectional, rather than longitudinal, particularly in studies of gay and bisexual men. Other psychological theories (e.g., self-perception or cognitive dissonance theories) suggest that the opposite could be true—that health-relevant attitudes and beliefs might change as a function of previous risk or precautionary behavior. Appreciating the complex nature of these associations is essential for modifying theory and developing appropriate interventions. Design: Using longitudinal data from gay and bisexual men (n = 1465), we used structural equation modeling to examine three possibilities—that perceived norms and attitudes about sexual risk would be (a) related to unprotected anal intercourse cross-sectionally, (b) related to unprotected anal intercourse at a subsequent time point, and/or (c) predicted from previous instances of unprotected anal intercourse. Results: Safe-sex norms and attitudes were related to unprotected anal intercourse cross-sectionally, but did not predict unprotected sex longitudinally. Rather, perceived norms and attitudes changed as a function of previous risk behavior. Conclusions: These results raise the possibility that modified theoretical models might be necessary to adequately describe sexual risk behavior among gay and bisexual men.

Objective: Young men who have sex with men (MSM), particularly young men of color, are experiencing the largest increase in HIV incidence of any risk group in the United States Epidemiological research suggests that the majority of transmissions among MSM are occurring in the context of primary partnerships, but little research has been done on the processes within these dyads that increase HIV risk behaviors. The aim of this study was to use longitudinal partnership-level data to explore the effects of partner and relationship characteristics on the frequency of unprotected sex within young MSM relationships. Method: One hundred twenty-two young MSM (age 16–20 at baseline) were assessed at three time-points six months apart, with 91% retention at the 12-month follow-up wave. Over 80% were racial/ethnic minorities. At each wave, participants reported on characteristics of the relationships and partners for up to three sexual partners. Hierarchical linear modeling was used for analyses. Results: The largest effect was for considering the relationship to be serious, which was associated with nearly an eightfold increase in the rate of unprotected sex. Other factors that increased risk behaviors included older partners, drug use prior to sex, physical violence, forced sex, and partnership lasting more than six months. Partners met online were not associated with significantly more sexual risk. Conclusions: These data provide insight into the relationship processes that should be addressed in prevention programs targeted at young MSM. Relationships may serve as a promising unit for HIV prevention interventions, although more formative research will be required to address potential logistical obstacles to implementing such interventions. The partner-by-partner analytic approach (i.e., evaluating situational variables associated with several partners for a given participant) holds promise for future HIV behavioral research.

Childhood sexual abuse (CSA) is associated with a wide range of negative outcomes. The authors investigated the relation between CSA and sexual risk behavior in 827 patients recruited from a sexually transmitted disease (STD) clinic. Overall, CSA was reported by 53% of women and 49% of men and was associated with greater sexual risk behavior, including more sexual partners, unprotected sex, and sex trading. Alcohol use for men and drug use for women mediated the relation between CSA and the number of sexual partners in the past 3 months; intimate partner violence mediated the relation between CSA and the number of episodes of unprotected sex in the past 3 months for women. These results document the prevalence of CSA among patients seeking care for an STD and can be used to tailor sexual risk reduction programs for individuals who were sexually abused.

Evidence of the effects of negative affect (NA) and sexual craving on unprotected sexual activity remains scant. We hypothesized that NA and sexual craving modify the same day association between low self-efficacy to use condoms and unprotected anal or vaginal sex, and the same-day association between alcohol use during the 3 hours prior to sexual activity and unprotected sex. We used an electronic daily diary, drawing on a sample of 125 men and women recruited from an agency serving economically disadvantaged persons living with HIV/AIDS. Casual or steady partner type designation and perceived partner HIV serostatus were also examined. Findings support the hypothesized moderating effects of high NA and sexual craving on the association between low self-efficacy and unprotected sex, and the association between alcohol use and unprotected sex. Implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

HIV and AIDS is a growing health risk for heterosexual women, particularly women of color (Centers for Disease Control and Prevention, 1997). Our research identified 5 types of HIV sexual risk taking in 3 independent samples of adult women from a New England Community: Group A women were noted by low to moderate levels of the 4 risk markers (i.e., unprotected vaginal sex, perceived partner-related risk, number of sexual partners, and unprotected anal sex); Group B women reported very high frequency of unprotected vaginal sex; Group C women were characterized by unprotected anal sex; Group D women had high perceived partner risk; and Group E women reported extremely high levels on all 4 HIV risk markers. Sexual risk groups were validated by demonstrating significant differences among groups on relevant behaviors, interpersonal experiences, and attitudes. Compared to other women, higher risk types reported greater behavioral risk practices (substance use, prostitution, diverse sexual experience), interpersonal risk experiences (sexual abuse, violence), initiation sexual assertiveness, and attitudinal risks (psychosocial distress). They reported less interpersonal assurance (surety of own and partner's HIV status), sexual assertiveness (for condom use and partner communication), psychosocial strengths (sexual self-acceptance), and transtheoretical readiness for change (condom use efficacy, readiness to consider condoms). Results provide additional support for the multifaceted model of HIV risk and the transtheoretical model. Suggestions for specifically focused interventions are given, depending on the pattern of sexual risk taking.  相似文献

Guided by the AIDS Risk Reduction Model (ARRM), psychosocial correlates of HIV risk behavior were examined among noninjection cocaine dependent, heterosexual men (NI-CD-HM) in treatment. Subjects (N = 111) completed a structured interview to measure ARRM mediating variables and HIV risk behaviors. The results indicated that greater perceived susceptibility to contracting HIV, lower sexual self-efficacy, higher lifetime incidence of sexually transmitted diseases, and being under the influence of alcohol or other drugs during sex predicted having more sexual partners in the month prior to admission. Despite adequate knowledge of safer sex guidelines, subjects remained misinformed regarding certain aspects of HIV transmission. Men who perceived that their partners viewed condoms more positively and who exchanged drugs for sex were more likely to use condoms, yet condom use skills were typically inadequate to ensure effective prevention. These results suggest that HIV prevention interventions among NI-CD-HM should focus on improving knowledge, enhancing beliefs in the capacity to enact safer sex behaviors for preventing HIV and other STDs, building relevant skills (e.g., condom use, open sexual communication between partners), and emphasizing psychoactive substance abstinence. Couple interventions, in which partners actually rehearse safer sex negotiations, may be particularly effective in this regard.  相似文献

A review of research on AIDS preventive behavior indicates that minority and nonminority heterosexual adolescents and adults, gay men, injection drug users, and commercial sex workers are all less likely to practice safer sex with close relationship partners, compared with partners they perceive to be "casual" sexual partners. Because many individuals in close relationships have engaged in HIV risk behavior over extended periods of time and are unaware of their actual HIV status, practicing unprotected sexual intercourse with a committed relationship partner who is not tested for HIV appears to be a major and unrecognized source of HIV risk. This article reviews the evidence for higher levels of HIV risk behavior in close relationships and then presents relevant conceptual and empirical work to explore the psychological processes that may underlie risky sexual behavior in close relationships, using as a framework the information-motivation-behavioral skills model of preventive behavior.

Gay male couples (N = 47) completed self-administered questionnaires at 2 time points (6 months apart) regarding their levels of general and HIV-specific social support and sexual behavior. HIV-specific social support measured partner support pertaining to HIV risk behavior. The sexual-risk-behavior outcome encapsulated monogamy, serostatus, and unprotected anal sex for each partner. The authors used an analytic approach that maintained the couple as the unit of analysis. General social support was an inconsistent predictor of HIV risk behavior. However, couples that reported greater levels of HIV-specific social support engaged in less HIV risk behavior at each time point as well as longitudinally. This study demonstrated the utility of measuring HIV-specific social support and its predictive ability related to HIV risk behavior.

Women account for a quarter of all new HIV/AIDS cases, with approximately 65% having contracted the infection via heterosexual contact. Few experimental studies have examined interactions among background, partner, and situational characteristics in predicting women's sexual decisions. The Cognitive Mediation Model provides a useful theoretical framework for assessing likelihood of unprotected sex. Female social drinkers (n = 230) who had answered questions related to their general intention to have unprotected sex were randomly assigned to an experimental condition based on partner risk level (unknown, low, high) and beverage (control, placebo, low dose, high dose). Participants projected themselves into a story depicting a sexual situation with a man and answered questions about their cognitive appraisals, assertive condom request, and likelihood of unprotected sex. Alcohol effects on appraisal of sexual potential differed by partner risk condition. In the unknown and low risk conditions, placebo and alcohol participants appraised the situation as having greater sexual potential than controls whereas in the high risk condition, only those who consumed alcohol did so. Sexual potential appraisals in turn predicted impelling cognitions about having sex, which in turn predicted assertive condom request and unprotected sex intentions. General intention for unprotected sex independently predicted cognitive appraisals and outcomes. These findings highlight the need for prevention programs that focus on teaching women how to pay attention and consider sexual risk cues presented by potential partners, particularly when under the influence of alcohol.

The current research presents the results of 2 related experimental studies designed to evaluate the influence of physical attractiveness and a moderate dose of alcohol on men's perceptions of potential sexual partners and sexual behavior intentions. Analyses revealed significant effects of physical attractiveness on partner perceptions and sexual behavior intentions. Although no main effects of alcohol were observed, alcohol differentially moderated the relations between perceived risk and sexual behavior intentions by limb of absorption. Results suggest that greater attention should be focused on identifying the specific physical characteristics of a potential sexual partner--beyond attractiveness--that influence perceptions of risk and intentions to engage in safer sex behaviors and highlight the importance of assessing limb of absorption in evaluating the complex association between alcohol and risky sexual behavior.

This research evaluated a motivation-based HIV risk reduction intervention for economically disadvantaged urban women. Participants completed a survey that assessed HIV-related knowledge, risk perceptions, behavioral intentions, sexual communication, substance use, and risk behavior. A total of 102 at-risk women (76% African American) were randomly assigned to either the risk reduction intervention or to a waiting list. Women were reassessed at 3 and 12 weeks. Results indicated that treated women increased their knowledge and risk awareness, strengthened their intentions to adopt safer sexual practices, communicated their intentions with partners, reduced substance use proximal to sexual activities, and engaged in fewer acts of unprotected vaginal intercourse. These effects were observed immediately, and most were maintained at follow-up.  相似文献

Researchers have identified the association between the use of cocaine and sexual behavior as an important risk factor for HIV infection and have attempted to elucidate the nature of this association. Several lines of research have suggested that facilitation of sexual behavior during intoxication with cocaine may be because of the direct pharmacological effects of the drug (e.g., increase in sexual desire), whereas others have pointed to the importance of factors related to the context of drug use (e.g., opportunities for sexual behavior, expectations about the effects of the drug, social norms). The present study explored the perceived effects of cocaine and heroin on sexual behavior, as well as the social context of drug use as a function of drug type (cocaine vs. heroin), among 46 inner-city drug users who reported a history of regular use of both crack cocaine and heroin. Results indicated that compared to heroin, cocaine had deleterious effects on participants' perceived sexual desire and performance. Despite such deleterious effects on sexual behavior, cocaine was more frequently used with an intimate partner than heroin. Furthermore, participants did not differ in the extent to which they used the two drugs in other social contexts (e.g., with friends, family, or neighbors). These preliminary results suggest that the relationship between cocaine and sexual behavior, especially among long-term cocaine users, may be facilitated by opportunities for sex that exist in the context of cocaine use, rather than by the pharmacological effects of the drug.

Objective: Beliefs about HIV treatment effectiveness and the impact of HIV treatments on HIV transmission risks were initially related to sexual risk-taking in the late 1990s when multidrug HIV treatments first became available. This study examined changes in beliefs about the effects of HIV treatment for preventing HIV transmission and their association to sexual risk behaviors between the years 1997 and 2005. Design: Anonymous surveys were administered to a convenience sample of gay and bisexual men attending a large community event in Atlanta, Georgia in 1997 (N = 498) and again at the same community event in 2005 (N = 448). Analyses were performed for men living with HIV/AIDS and for men who have not been diagnosed with HIV/AIDS. Main Outcome Measures: Rates of unprotected anal intercourse in the previous 3 months. Results: There were significant increases in high-risk sexual practices that coincided with increased beliefs that HIV treatments can reduce the chance of transmitting HIV. However, optimistic beliefs about the health benefits of HIV treatments decreased over the 8 years and were not related to risk behaviors. Conclusions: Beliefs about how HIV treatments impact HIV infectiousness remain associated with HIV transmission risk behavior and interventions targeting at-risk as well as HIV-positive men who have sex with men must directly address these beliefs and perceptions.

The authors examined the contributions of the minority stress model, traditional masculine gender roles, and perceived social norms in accounting for gay men's use of alcohol, tobacco, illicit drugs, and risky sexual practices. Three hundred fifteen gay men recruited from listserv communities completed measures assessing internalized homophobia, stigma, antigay physical attack, masculinity, and perceptions of normative health behaviors, along with health risk behaviors of alcohol use, illicit drug use, smoking, and high-risk sexual behaviors. Pearson correlations supported several hypotheses; social norms and masculinity variables were significantly related to health risk behaviors. Four multiple regression analyses indicated that masculinity and perceptions of social norms predicted health risk behaviors. Additionally, a significant interaction was found between minority stress and perceptions of social norms. The clinical implications of the findings, limitations, and suggestions for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

1. Students in this study appraised their AIDS risk using their sexual and drug-use behavior as criteria, which accurately reflects their knowledge of HIV transmission. 2. AIDS risk perceptions were not always congruent with the students' self-reported sexual and drug use behavior. Some students reporting high-risk behavior perceived their AIDS risk as "nil" or "small." 3. Perceived riskiness of behavior increased as distance from the students increased. The students viewed their friends' AIDS risk as moderately greater than their own risk and their peers' risk even greater.  相似文献

When are perceivers guided more by implicit social-cognitive theories of personality and when more by trait theories? As perceivers become more familiar with a person they infer relatively more psychological mediating variables (e.g., construals, goals) that underlie the person's behavior and relatively fewer broad, uncontextualized traits such as aggressive or friendly (Study 1). The effects of familiarity are moderated by the importance of the target to perceivers (Study 2). Specifically, perceivers make relatively more inferences using mediating variables and fewer inferences with traits as the target becomes more familiar, if and only if the target plays an important role in their lives. The findings indicate that psychological mediating variables play a significant role in lay perceptions of people and specify conditions in which perceivers function like implicit social-cognitive theorists, namely, when the perceived is familiar and important to the perceiver.

Background: Risk perceptions are central to many health behavior theories. However, the relationship between risk perceptions and behavior, muddied by instances of inappropriate assessment and analysis, often looks weak. Method: A meta-analysis of eligible studies assessing the bivariate association between adult vaccination and perceived likelihood, susceptibility, or severity was conducted. Results: Thirty-four studies met inclusion criteria (N = 15,988). Risk likelihood (pooled r = .26), susceptibility (pooled r = .24), and severity (pooled r = .16) significantly predicted vaccination behavior. The risk perception-behavior relationship was larger for studies that were prospective, had higher quality risk measures, or had unskewed risk or behavior measures. Conclusions: The consistent relationships between risk perceptions and behavior, larger than suggested by prior meta-analyses, suggest that risk perceptions are rightly placed as core concepts in theories of health behavior.
