HIV risk reduction interventions for persons with severe mental illness

Recent seroprevalence studies have shown alarming rates of HIV infection among severely mentally ill men and women in large urban areas, and HIV behavioral epidemiology research indicates that a substantial proportion of seriously mentally ill adults engage in activities that increase their vulnerability to HIV/AIDS. In this paper, the research literature on HIV prevention interventions is reviewed including reports that have described HIV prevention programs, studies that have used uncontrolled pre- and postintervention methods to evaluate risk reduction interventions, and those that have used rigorous randomized designs and examined risk behavior change. Collectively, these studies show that intensive, small-group interventions that target a variety of risk-related dimensions-including knowledge, attitudes, and motivations, and behavioral and cognitive skills-can produce at least short-term reductions in high-risk sexual behavior among the severely mentally ill. A number of gaps in the research literature are identified including the need to: (a) better tailor interventions to risk situations encountered by the mentally ill; (b) develop gender-tailored interventions; (c) examine and implement HIV prevention programs so they help persons sustain behavior change; (d) explore one-on-one counseling and community-level intervention methods; and (e) develop risk reduction interventions for already-seropositive individuals. Implications for service provision are discussed.     

Internalized heterosexism among HIV-positive, gay-identified men: Implications for HIV prevention and care.

Internalized heterosexism (IH), or the internalization of societal antihomosexual attitudes, has been consistently linked to depression and low self-esteem among gay men, and it has been inconclusively associated with substance use and sexual risk in gay and bisexual men. Using structural equation modeling, the authors tested a model framed in social action theory (C. K. Ewart, 1991, 2004) in which IH is associated with HIV transmission risk and poor adherence to HIV antiretroviral therapy (ART) through the mechanisms of negative affect and stimulant use. Data from a sample of 465 gay-identified men interviewed as part of an HIV risk reduction behavioral trial were used to test the fit of the model. Results support the hypothesized model in which IH was associated with unprotected receptive (but not insertive) anal intercourse with HIV-negative or unknown HIV status partners, and with ART nonadherence indirectly via increased negative affect and more regular stimulant use. The model accounted for 15% of the variance in unprotected receptive anal intercourse and 17% of the variance in ART nonadherence. Findings support the potential utility of addressing IH in HIV prevention and treatment with HIV-positive gay men. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Prevalence of high-risk sex among HIV-positive gay and bisexual men: a longitudinal analysis

INTRODUCTION: This longitudinal study examined the prevalence and demographic correlates of unprotected insertive and receptive anal intercourse among HIV-positive gay and bisexual men who were aware of their serostatus. METHODS: Participants (n = 395), sampled randomly at two HIV outpatient clinics in Los Angeles, completed two waves of self-administered questionnaires (separated by approximately 7-9 months) that measured sexual behaviors in the previous 60 days. RESULTS: The cross-sectional prevalence of unprotected insertive anal intercourse was 11.2% at time 1 and 7.1% at time 2. Longitudinal analysis indicated that nearly 15% of the participants had engaged in that high-risk behavior either at time 1 or time 2 and approximately 4% had engaged in the behavior at each time period. Similar rates of unprotected receptive anal intercourse were observed. These high-risk activities were more prevalent with seropositive and unknown serostatus partners than with seronegative partners. The rate of anal intercourse risk behaviors was higher among asymptomatic men and among those who were exclusively gay. CONCLUSION: The findings demonstrate considerable differences in the prevalence of stable and occasional high-risk sexual behaviors among HIV-positive gay and bisexual men. Simple cross-sectional analyses cannot capture the stability or variation in behavior across time and, thus, may generate misleading conclusions about disease transmission, especially if the partner's HIV serostatus is not considered in the analysis. The findings indicate a need for focused safer-sex interventions for seropositive men. The HIV outpatient clinic is an ideal setting for such interventions.     

Risk for HIV infection among bisexual men seeking HIV-prevention services and risks posed to their female partners.

The present study interviewed gay (n?=?473) and bisexual men (n?=?146) as part of an HIV prevention program and investigated social cognitive factors associated with HIV risk. Results indicated that HIV risk in homosexual men was associated with sexual openness and connections to gay communities, factors not associated with risk for bisexual men. Compared with men at lower risk, those who practiced high-risk sex scored lower on measures of perceived safer sex norms, safer sex self-efficacy, and social skills. Bisexual men with primary female partners often had not disclosed their bisexuality to female partners (75%), and 64% had not modified their behavior to protect female partners. Bisexual men who engage in high-risk behaviors therefore pose a risk to female partners who may be unaware of their involvement with men.

"Ruling in" and "ruling out": two approaches to the micro-rationing of health care

Seropositive gay and bisexual men who reveal their sexual orientation or HIV/AIDS status to their employer risk discriminatory reprisals. However, non-disclosure may limit potential social, emotional, and tangible support. Among our sample of 389 seropositive gay and bisexual men employed in the US, 52% were 'out' to their employer and 35% had disclosed their serostatus to him or her. Among gay men, employer awareness of their sexual orientation was related to their being European American (vs Latino or African American), being HIV-seropositive for more than 4 years, and having a gay or bisexual employer. Disclosure of HIV infection in the total sample was related to being European American, HIV-seropositive for more than 4 years, symptomatic (vs asymptomatic), 'out' at work, and having a gay or bisexual employer. Men who had informed their employers of their HIV status reported consequences that were substantially more positive than those anticipated by men who had not disclosed. Policy and research implications for improving the work environment for gay and bisexual men living with HIV are considered.     

The sexual negotiation behavior of HIV-positive gay and bisexual men.

This study describes the sexual negotiation practices of 256 HIV-positive gay and bisexual men enrolled in a sexual risk reduction intervention. Negotiation behavior was associated with sexual risk practices. Men who abstained from anal sex and those who had unprotected anal sex had the lowest negotiation scores. Negotiations occurred most often with steady partners and least often with anonymous partners. A logistic regression to predict high versus low frequency negotiators revealed the significance of self-efficacy for condom use and number of months HIV-positive. Findings are discussed in terms of the development of sexual risk reduction interventions for HIV-positive gay and bisexual men. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cost-effectiveness of a community-level HIV risk reduction intervention

OBJECTIVES: The authors evaluated the cost-effectiveness of a community-level HIV prevention intervention that used peer leaders to endorse risk reduction among gay men. METHODS: A mathematical model of HIV transmission was used to translate reported changes in sexual behavior into an estimate of the number of HIV infections averted. RESULTS: The intervention cost $17,150, or about $65,000 per infection averted, and was therefore cost-saving, even under very conservative modeling assumptions. CONCLUSIONS: For this intervention, the cost of HIV prevention was more than offset by savings in averted future medical care costs. Community-level interventions to prevent HIV transmission that use existing social networks can be highly cost-effective.     

Within-group differences in sexual orientation and identity.

The purpose of this investigation was to examine within-group differences among self-identified sexual orientation and identity groups. To understand these within-group differences, 2 types of analysis were conducted. First, a sample of 2,732 participants completed the Sexual Orientation and Identity Scale. Cluster analyses were used to identify 3 types of bisexual women, 3 types of bisexual men, 2 types of heterosexual women, and 2 types of gay men. Lesbians and heterosexual men were clustered into singular groupings. In addition, a subsample of 838 participants also completed measures of sexual identity development and lesbian, gay, and bisexual knowledge and attitudes. Within-group differences were found for bisexual men and women, gay men, and heterosexual women along these dimensions. Findings supported the existence of distinct subgroups of bisexual men, bisexual women, gay men, and heterosexual women. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

HIV infection risks among homeless, mentally ill, chemical misusing men

This study attempts to identify the specific role that each of three conditions afflicting homeless, mentally ill, chemically misusing (HMICM) men plays in exposing these men to the risk of HIV infection. Three hundred and fifteen HMICM men (33 of whom were HIV+) were interviewed on intravenous drug use (IVDU) and sex practices. Two scales of risky IVDU practices and sex conducts were constructed and analyzed in relation to HIV status. The severity of homelessness, mental illness, and chemical misuse, then, were analyzed as possible predictors of risky IVDU and sex practices. Strong correlations were found between IVDU practices and HIV seropositivity, and between risky sex conduct and HIV seropositivity. Serious depression was the strongest predictor of risky IVDU practices. Prolonged homelessness was the condition most associated with risky sexual conduct. This study concludes that HMICM men are at high risk for HIV infection, stemming, predominately, from two conditions: depression, leading to risky IVDU practices, and homelessness, leading to risky sex conduct with two separate types of risky behavior.     

Mental health and substance use disorders among Latino and Asian American lesbian, gay, and bisexual adults.

Growing evidence suggests that lesbian, gay, and bisexual adults may be at elevated risk for mental health and substance use disorders, possibly due to anti-gay stigma. Little of this work has examined putative excess morbidity among ethnic/racial minorities resulting from the experience of multiple sources of discrimination. The authors report findings from the National Latino and Asian American Survey (NLAAS), a national household probability psychiatric survey of 4,488 Latino and Asian American adults. Approximately 4.8% of persons interviewed identified as lesbian, gay, bisexual, and/or reported recent same-gender sexual experiences. Although few sexual orientation-related differences were observed, among men, gay/bisexual men were more likely than heterosexual men to report a recent suicide attempt. Among women, lesbian/bisexual women were more likely than heterosexual women to evidence positive 1-year and lifetime histories of depressive disorders. These findings suggest a small elevation in psychiatric morbidity risk among Latino and Asian American individuals with a minority sexual orientation. However, the level of morbidity among sexual orientation minorities in the NLAAS appears similar to or lower than that observed in population-based studies of lesbian, gay, and bisexual adults.

Reinforcement value of unsafe sex as a predictor of condom use and continued HIV/AIDS risk behavior among gay and bisexual men.

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. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The African-American Health Project (AAHP): study overview and select findings on high risk behaviors and psychiatric disorders in African American men

The AAHP investigated the neurobehavioral and psychosocial sequelae of HIV-1 and substance use in urban African American men. A community resident sample of 502 African American men stratified by HIV-1 serostatus, drug use and sexual orientation were recruited. A comprehensive battery of measures of neurobehavioral and health status, lifestyle and psychosocial characteristics were administered to all participants, and a stratified sub-sample of 120 participants were tested using state of the art brain imaging techniques to investigate differences in the functional and neurophysiologic effects of HIV-1 and substance use. An overview of the methodology of the AAHP and results on high risk sexual and substance use behaviors, and psychiatric disorders are presented and discussed. The sample was primarily HIV-negative (63%), heterosexual (49% gay or bisexual) and a high percentage used substances during the past year (56% used drugs and 30% moderate/heavy drinkers). High-risk sexual practices were relatively prevalent, and a high percentage reported a history of STDs and other infections. Finally, 25% had a current psychiatric disorder, with gays/bisexuals and HIV-seropositives evidencing greater psychiatric vulnerability. More research is needed to further explore the apparent greater risk for psychiatric disorders among gay and bisexual men, and to determine whether being African American and lower social class exacerbate this risk.     

Effects of disengagement coping with HIV risk on unprotected sex among HIV-negative gay men in New York City.

Objective: This study examined how disengagement coping with HIV risk mediated the association between internalized homophobia and unprotected anal intercourse (UAI) and how sexual encounters in public venues (public sex) and drug use moderated the association between disengagement coping and UAI among HIV-negative gay men. Disengagement coping included fatalistic beliefs about maintaining HIV-negative seronegative serostatus (fatalism), optimistic attitudes toward medical seriousness of HIV infection and reduced concern about HIV risk due to highly active anti-retroviral therapies (optimism), and negative affective states associated with sexual risk (anxiety). Design: A survey was conducted among 285 HIV-negative gay men at an HIV prevention counseling program in New York City. Main Outcome Measures: Sexual risk was defined as having had UAI with nonprimary partners in the past 6 months. Results: In addition to the positive association between internalized homophobia, disengagement coping, and UAI, fatalism mediated the association between internalized homophobia and UAI; and optimism mediated the association between anxiety and UAI. A significant moderation effect of public sex was found between fatalism and UAI. Conclusions: The findings highlight the importance of understanding disengagement coping as it affects sexual risk practices among HIV-negative gay men in the continuing epidemic.

AIDS treatment advances and behavioral prevention setbacks: Preliminary assessment of reduced perceived threat of HIV–AIDS.

Recent advances in AIDS treatment have brought renewed optimism for prolonging the lives of those infected with HIV. This article examined beliefs about how new treatments may reduce HIV transmission risk among 298 HIV-negative gay and bisexual men attending a gay pride festival. Results from an anonymous survey showed that men who practiced unprotected anal intercourse as the receptive partner (UAR intercourse) were younger, less well educated, and more likely to believe that it is safe to have UAR intercourse with an HIV-positive man who has an undetectable viral load and that new treatments for HIV relieve their worries about unsafe sex. As HIV treatments continue to advance, new challenges for HIV prevention will likely emerge. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality and cognitive factors influencing substance use and sexual risk for HIV infection among gay and bisexual men.

Substance use reliably predicts sexual risk behavior, and sensation-seeking personality characteristics have been found to covary with these associations. In a study of 289 gay and bisexual men attending a large gay pride event, the authors examined the role of substance use sexual outcome expectancies in explaining associations between sensation seeking, substance use, and risky sex. Consistent with previous research, alcohol and other drugs were associated with sexual behavior. However, path analyses showed that sensation seeking accounted for variance in sexual behavior over and above substance use before sex and that sensation seeking predicted substance use expectancies that in turn predicted substance use before sex. It was concluded that altering substance use outcome expectancies may be an important strategy for HIV risk reduction for individuals high in sensation seeking.

Risk for human immunodeficiency virus (HIV) infection among persons with severe mental illnesses

Individuals diagnosed with a severe mental illness are at significantly enhanced risk for infection with the human immunodeficiency virus (HIV). To better understand elevated seroprevalence in this population, we review the research literature that has investigated HIV-related risk behavior among adults who have a severe and persistent mental illness. This review indicates that 54%-74% of adults report that they have been sexually active in the last year with approximately one third reporting two or more partners. Among those who were sexually active, condom use was inconsistent. A significant minority (4%-35%) of adults also reported a history of injection drug use. Overall, the data indicate that the severely mentally ill engage regularly in practices known to involve increased risk for HIV transmission. We introduce and modify Fisher and Fisher's (1992) theoretical model to organize the possible determinants of HIV-related risk taking among severely mentally ill adults, and encourage use of this model in the design of behavioral epidemiological and risk reduction studies. We also identify several methodological challenges to HIV-related research, including problems associated with the use of self-report measures; diagnostic imprecision; and participant recruitment and retention.     

HIV prevention with male prostitutes and patrons of hustler bars: replication of an HIV preventive intervention

The core objectives of this study were to document the process by which a community-based organization replicated and adapted an experimentally developed intervention to its own use and to explore the effectiveness of that HIV prevention program for male prostitutes and other patrons in New York City "hustler" bars. The intervention model employed was based on previous research with gay men (Kelly, St. Lawrence, Diaz, et al., 1991; Kelly, St. Lawrence, Stevenson, et al., 1992) and inspired by diffusion of innovation theory (Rogers, 1995). The effects of the current intervention were assessed on a sample of 1,741 male prostitutes and bar patrons. Analyses indicated significant reductions in paid, unprotected sexual intercourse and oral sex following the intervention. Analyses further indicated that the data were partially consistent with the program's model, which specified that norms were the putative mediator of behavior change in the intervention. Also, the intervention's effects varied by bar and by participants' race/ethnicity. Data support the utility of the intervention model for an urban sample of men at high risk for HIV infection. The importance of exploring the mechanisms that underlie the intervention is discussed.     

The Treatment Advocacy Program: A randomized controlled trial of a peer-led safer sex intervention for HIV-infected men who have sex with men.

Objective: Primary care may be an effective venue for delivering behavioral interventions for sexual safety among HIV-positive men who have sex with men (MSM); however, few studies show efficacy for such an approach. We tested the efficacy of the Treatment Advocacy Program (TAP), a 4-session, primary-care-based, individual counseling intervention led by HIV-positive MSM “peer advocates” in reducing unprotected sex with HIV-negative or unknown partners (HIV transmission risk). Method: We randomized 313 HIV-positive MSM to TAP or standard care. HIV transmission risk was assessed at baseline, 6 months, and 12 months (251 participants completed all study waves). We conducted intent-to-treat analyses using general estimating equations to test the interaction of group (TAP vs. standard care) by follow-up period. Results: At study completion, TAP participants reported greater transmission risk reduction than did those receiving standard care, χ2(2, N = 249) = 6.6, p = .04. Transmission risk among TAP participants decreased from 34% at baseline to about 20% at both 6 and 12 months: Transmission risk ranged from 23% to 25% among comparison participants. Conclusions: TAP reduced transmission risk among HIV-positive MSM, although results are modest. Many participants and peer advocates commented favorably on the computer structure of the program. We feel that the key elements of TAP—computer-based and individually tailored session content, delivered by peers, in the primary care setting—warrant further exploration.

Sexual orientation, sexual behaviors, and pregnancy among American Indian adolescents

PURPOSE: A recent study found a disproportionate number of pregnancies among Euro-American lesbian and bisexual adolescents compared to heterosexual peers. American Indian adolescents have reported higher prevalence of gay/lesbian/bisexual orientations than Euro-Americans; do they also report higher prevalence of pregnancy? METHODS: The study assessed prevalence of teen pregnancy and related factors by sexual orientation among sexually experienced, reservation-based American Indian adolescent males (n = 2056) and females (n = 1693) who participated in a national school-based survey in 1991. Self-reported orientation was classified as heterosexual, gay/lesbian/bisexual, and "unsure" of orientation. RESULTS: Gay/bisexual males were more likely than other males to report early heterosexual intercourse (<14 years), more consistent contraception, and a higher prevalence of abuse and running away (p < 0.05 to p < 0.0001). Likewise, lesbian/bisexual females were more likely to report early onset of heterosexual intercourse, more frequent intercourse, and running away. Sexual or physical abuse did not vary by orientation for females. Prevalence of pregnancy also did not vary by orientation (males, 18.6% gay/bisexual vs. 10.4% "unsure" vs. 11.8% heterosexual; females, 25.0% lesbian/bisexual vs. 22.1% "unsure" vs. 21.9% heterosexual). For lesbian/bisexual females, no variables were significantly associated with pregnancy history; for "unsure" females, pregnancy was associated with contraceptive frequency and early onset of heterosexual activity. For heterosexual females, age, intercourse frequency, and physical abuse were associated. For gay/bisexual males, intercourse frequency, ineffective contraception, and physical abuse were associated with involvement in a pregnancy; for "unsure" and heterosexual males, most items except ineffective contraception were related to pregnancy involvement history. CONCLUSIONS: Although prevalence of pregnancy is similar, findings show group differences in associated risk factors by sexual orientation. Interventions to reduce pregnancy among American Indian adolescents should include assessment of sexual orientation and behavioral risk factors.     

Family moderators of the relation between hassles and behavior problems in inner-city youth

Qualitative data from individual interviews with 18-29 year old African American men, who have sex with men (n = 76) were used to examine the relationship of negative attitudes toward homosexuality, self-esteem, and risk for HIV. Respondents perceived members of their communities as holding negative attitudes toward homosexuality, and many thought the African American community was less accepting of homosexuality than the white community. There was evidence that these negative attitudes are internalized by some of the young African American men themselves. Respondents mentioned several ways that negative attitudes toward homosexuality could lead to lower self-esteem and psychological distress in young gay and bisexual men. In addition, respondents articulated several mechanisms by which low self-esteem and psychological distress might be associated with sexual behaviors that put one at risk for HIV. We concluded that addressing and changing society's negative views of homosexuality are important components of a comprehensive approach to reducing the transmission of HIV, especially among young people in communities of color.
