Towards an Understanding of Risk Behavior: An AIDS Risk Reduction Model (ARRM)

This report presents a three-stage model (ARRM) that characterize peoples efforts to change sexual behaviors related to HIV transmission. ARRM focuses on social and psychological factors hypothesized to influence (1) labeling of high risk behaviors as problematic, (2) making a commitment to changing high risk behaviors, and (3) seeking and enacting solutions directed at reducing high risk activities. The proposed model integrates important concepts from prior behavioral medicine and human sexuality stud ies, specifies their differential import to achieving the goals associated with each stage of the model, and denotes factors hypothesized to influence peoples motivation to con tinue the change process over time. Current findings are discussed within this three-stage model and directions for further research are suggested. Recent findings from our ongoing studies of gays and heterosexuals in San Francisco are presented.

Sexually active adolescents and condoms: changes over one year in knowledge, attitudes and use.

Over a year when public health information regarding AIDS intensified, changes in perceptions and use of condoms in a sample of sexually active adolescents in San Francisco were examined. Although perceptions that condoms prevent sexually transmitted diseases (STDs) and the value and importance placed on avoiding STDs remained high, these were neither reflected in increased intentions to use condoms nor in increased use.

Experiences of Harassment, Discrimination, and Physical Violence Among Young Gay and Bisexual Men

OBJECTIVES We examined the 6-month cumulative incidence of anti-gay harassment, discrimination, and violence among young gay/bisexual men and documented their associations with mental health. METHODS Gay/bisexual men from 3 cities in the southwestern United States completed self-administered questionnaires. RESULTS Thirty-seven percent of men reported experiencing anti-gay verbal harassment in the previous 6 months; 11.2% reported discrimination, and 4.8% reported physical violence. Men were more likely to report these experiences if they were younger, were more open in disclosing their sexual orientation to others, and were HIV positive. Reports of mistreatment were associated with lower self-esteem and increased suicidal ideation. CONCLUSIONS Absent policies preventing anti-gay mistreatment, empowerment and community-building programs are needed for young gay/bisexual men to both create safe social settings and help them cope with the psychological effects of these events.

Condom use in multi-ethnic neighborhoods of San Francisco: the population-based AMEN (AIDS in Multi-Ethnic Neighborhoods) Study.

We examined the prevalence and correlates of condom use in a community-based sample of unmarried heterosexual and gay/bisexual Whites, Blacks, and Hispanics (aged 20 to 44 years) in San Francisco (n = 1229). Only 9% of heterosexual males reported always using condoms, and fewer of those with multiple sexual partners (6%) reported always using condoms compared with those in monogamous relationships (12%). Much higher proportions of gay/bisexual men reported always using condoms (48%). Racial differences in condom use were observed only among women. Sexual communication and the sexual enjoyment value of condoms were consistent correlates of condom use across gender and sexual orientation, while other condom-related beliefs were significant predictors of condom use only for men. In general, condom promotion programs should build sexual communication skills, teach people how to enhance enjoyment with condoms, and reduce psychological barriers to condom acquisition and use.

High Hiv risk-taking among young gay men

Previous research has shown younger age to be correlated with greater HIV sexual risk-taking among gay men. The purpose of this study was to identify variables associated with HIV risk-taking among younger gay men. Ninety-nine gay men aged 18-25 in three medium-sized West Coast communities completed self-report questionnaires regarding HIV-related behaviors and attitudes. Of the respondents, 43% reported having engaged in unprotected anal intercourse during the previous 6 months. Men who engaged in unprotected anal intercourse reported greater enjoyment of unprotected anal intercourse, perceived less risk of unprotected anal intercourse, labeled themselves as more at risk for AIDS, reported poorer communication skills with sexual partners, and were more likely to have a boyfriend/lover than men who had not engaged in high-risk sex. In addition, respondents perceived the likelihood of acquiring HIV from unprotected anal intercourse with young gay men to be significantly lower than with older gay men. These findings highlight the need for HIV risk-reduction interventions designed specifically for young gay men and identify critical areas to be targeted in such interventions.

Initiation of substance use in early adolescence: the roles of pubertal timing and emotional distress.

Two hypotheses regarding the effects of pubertal timing on substance use were tested in a prospective study of 221 young adolescents. A maturational-deviance hypothesis predicted that early-maturing girls and late-maturing boys would experience heightened emotional distress, which in turn would influence initiation and use of substances. Alternatively, an early-maturation hypothesis predicted that early-maturing girls would engage in more substance use than all other groups, independent of emotional distress. Early-maturing adolescents reported more substance use within 1 year. Adolescents experiencing elevated levels of negative affect also reported greater substance use within the next year. However, pubertal timing was not related to emotional distress. Results support the early-maturation hypothesis for girls and suggest its extension to boys.

Pregnancy and contraception use among urban Rwandan women after HIV testing and counseling.

OBJECTIVES This study examined hormonal contraceptive use and pregnancy in urban Rwandan women, following human immunodeficiency virus (HIV) antibody testing and counseling. METHODS A sample of 1458 childbearing urban Rwandan women aged 18 to 35 years was tested and followed for 2 years. RESULTS At enrollment, 17% of 998 HIV-negative women and 11% of 460 HIV-positive women were pregnant, and 17% vs 23%, respectively, were using hormonal contraceptives. One year later, half of the HIV-positive and one third of the HIV-negative hormonal-contraceptive users had discontinued use. The 2-year incidence of pregnancy was 43% in HIV-positive and 58% in HIV-negative women. HIV-positive women with fewer than four children were more likely to become pregnant than those with four or more; this association persisted in multivariate analyses but was not noted among HIV-negative women. At the end of the study, over 40% of non-users said that they would use hormonal contraception if it was provided at the study clinic, but 40% of HIV-positive women desired more children. CONCLUSIONS Research is needed to identify the practical and psychosocial obstacles to effective long-term contraception among HIV-positive women. HIV counseling programs must specifically address the issue of childbearing.

The Role of Community Advisory Boards: Involving Communities in the Informed Consent Process

Ethical research involving human subjects mandates that individual informed consent be obtained from research participants or from surrogates when participants are not able to consent for themselves. The existing requirements for informed consent assume that all study participants have personal autonomy; fully comprehend the purpose, risks, and benefits of the research; and volunteer for projects that disclose all relevant information. Yet contemporary examples of lapses in the individual informed consent process have been reported. The authors propose the use of community advisory boards, which can facilitate research by providing advice about the informed consent process and the design and implementation of research protocols. These activities could help reduce the number of individual informed consent lapses, benefiting study participants and the scientific integrity of the research in question.

Actual versus perceived HIV status, sexual behaviors and predictors of unprotected sex among young gay and bisexual men who identify as HIV-negative, HIV-positive and untested.

Objectives:To compare the prevalence and predictors of HIV sexual risk behavior among young gay and bisexual men who perceived themselves to be HIV-negative, HIV-positive, or who were untested. Design:Population-based sample of young gay and bisexual men. Methods:Using multi-stage probability sampling, 408 gay and bisexual men aged 18–29 years in San Francisco were recruited and interviewed, and blood samples for HIV-testing from 364 participants were obtained. Results:HIV prevalence was 18.7%, although 25% of the men who were HIV-positive did not know it. Thirty-seven per cent reported engaging in unprotected anal intercourse during the past year, including 59% of the men who knew they were HIV-positive, 35% of the men who perceived themselves HIV-negative and 28% of the untested men. Logistic regressions found similar predictors of unprotected intercourse for HIV-negatives and HIV-positives, including sexual impulsivity, substance use, sexual enjoyment and communication problems. Conclusions:The high rates of unprotected intercourse, particularly among the HIV-positive men, attest to the urgent need for HIV-prevention interventions for young gay and bisexual men. The findings suggest that many of the important variables to target in interventions are similar for both HIV-positive and HIV-negative men.

A test of the AIDS Risk Reduction Model: Psychosocial correlates of condom use in the AMEN cohort survey.

We examined the AIDS Risk Reduction Model (J. Catania, S. Kegeles, & T. Coates) in a sample of unmarried heterosexual adults with an HIV risk factor (n = 716). Labeling ones sexual behavior as risky was associated with having a history of sexually transmitted diseases, particularly genital herpes, and fewer stereotypic health beliefs. For people with secondary sexual partners, greater condom commitment was related to increased labeling, supportive condom norms, and greater enjoyment, and high levels of condom use were related to greater condom commitment, supportive norms, greater enjoyment, and health protective sexual communication. For people with primary partners, greater condom commitment was correlated with increased supportive condom norms, greater enjoyment, and having genital herpes, and high levels of condom use were correlated with greater condom commitment, greater enjoyment, and health protective sexual communication.
