Risk factors for HIV-AIDS among youth in Cape Town, South Africa

South Africa is in the midst of a devastating HIV-AIDS epidemic and most new HIV infections occur among young adults and adolescents. The current study examined risk behaviors and HIV risk factors among young people living in a Black South African township. Using community-based outreach methods of street intercept and facility-based surveying, 113 men and 115 women age 25 and younger responded to an anonymous survey. Results showed that men (68%) and women (56%) reported HIV-related high risk sexual behaviors. Although knowledge about HIV transmission was generally high, there was evidence that misconceptions about AIDS persist, particularly myths related to HIV transmission. For young men, HIV risk factors were associated with fewer years of education, lower levels of AIDS-related knowledge, condom attitudes, and Dagga (marijuana) use. Among young women, HIV risk factors were associated with beliefs that condoms get in the way of sex and rates of unprotected vaginal intercourse. Despite adequate general AIDS knowledge and risk sensitization, South African youth demonstrated high rates of sexual practices that place them at risk for HIV infection. There is an urgent need for behavioral interventions targeted to young South Africans living in the most economically disadvantaged areas.

Assessing medication adherence self-efficacy among low-literacy patients: development of a pictographic visual analogue scale

Health behavior interventions are often grounded in Social Cognitive Theory, but instruments used to assess self-efficacy rely on verbal skills and yield scores that are highly positively skewed. Based on a review of the research literature and qualitative research with key informants, a pictographic medication adherence self-efficacy scale was developed. Two studies were conducted to test the pictographic and color visual analogue scale for assessing self-efficacy for medication adherence. Study 1 (N = 81) demonstrated that the pictographic self-efficacy scale was internally consistent (alpha = 0.68), time stable (2-week test-re-test r = 0.63), and showed evidence for convergent and divergent construct validity. Study 2 (N = 64) further supported the reliability of the pictographic self-efficacy scale with additional data supporting its convergent, divergent and criterion-related validity, including associations with medication adherence and HIV viral load. Distributions of self-efficacy scores approximated normal. This newly developed pictographic scale may be useful in assessing medication adherence self-efficacy in lower-literacy populations.

The other side of the healthy relationships intervention: mental health outcomes and correlates of sexual risk behavior change

Healthy Relationships is a small-group, social cognitive theory-based HIV prevention intervention designed for people living with HIV/AIDS. The Healthy Relationships intervention was demonstrated effective in a controlled randomized clinical trial. The intervention also integrated stress reduction with sexual risk reduction techniques, but the mental health outcomes from the intervention have not yet been reported. This study examined the 6-month follow-up mental health outcomes of the Healthy Relationships intervention among 81 HIV-positive study participants (45 in the Healthy Relationships condition and 36 in the health maintenance control condition) who reported sexual relationships with HIV-negative or unknown HIV status (nonconcordant) partners. Compared with the time-matched control condition, the Healthy Relationships intervention demonstrated significant reductions in perceived HIV-related stress. There was also evidence that reductions in perceived HIV-related stress mediated the intervention effects on sexual risk behaviors with nonconcordant partners. Results have implications for designing the next generation of HIV prevention interventions targeted to people living with HIV/AIDS.

Theory-based HIV risk reduction counseling for sexually transmitted infection clinic patients in Cape Town, South Africa

BACKGROUND

South Africa has the world's fastest growing AIDS epidemic. There is an urgent need for effective HIV risk reduction interventions in South Africa.

OBJECTIVE

The objective of this study was to develop and test the potential efficacy of a brief theory-based HIV prevention counseling intervention for sexually transmitted infection (STI) clinic patients in South Africa.

METHOD

STI clinic patients in Cape Town (N=228) were assessed at baseline and randomized to receive either: 1) a single 60-minute session motivational/skills-building HIV risk reduction counseling intervention or 2) a 20-minute HIV information/education session. Participants completed 1- and 3-month follow ups with 80% retention.

RESULTS

The 60-minute motivational/skills risk reduction counseling demonstrated significantly greater risk reduction practices, lower rates of unprotected intercourse, and greater likelihood of receiving HIV testing after the intervention.

CONCLUSIONS

Brief theory-based HIV prevention counseling may significantly reduce HIV risk behaviors for STI clinic patients in South Africa.

Sexual assault history and risks for sexually transmitted infections among women in an African township in Cape Town, South Africa

Sexual violence is associated with women's risks for HIV infection. The current study investigated factors related to risks for sexually transmitted infections (STIs), including HIV, among South African women with a history of sexual assault. An anonymous street intercept survey of women (N = 272) living in an African township in the Western Cape, South Africa assessed demographic characteristics, history of sexual assault, HIV risk behaviours, substance use and non-sexual relationship abuse. Surveys were completed by 90% of women approached. Forty-four per cent (N = 119) of women reported a history of sexual assault. Multiple logistic regressions, controlling for participant age, education, marital status and survey venue, showed that women who had been sexually assaulted were significantly more likely to have shared injection drug equipment, exchanged sex to meet survival needs, and used alcohol compared to women who had not been sexually assaulted. Women with a history of sexual assault were also significantly more likely to have multiple male sex partners, greater rates of unprotected vaginal intercourse, lower rates of condom protected anal intercourse, more sexual contacts involving blood, more STIs and genital ulcers. Finally, women who had been sexually assaulted were more likely to have been non-sexually abused by relationship partners and were more likely to fear asking partners to use condoms. There is a close connection between sexual assault and women's risks for STIs and HIV. Structural and behavioural interventions are needed to simultaneously reduce the prevalence of sexual assault against women and prevent the transmission of HIV.

Alcohol use and sexual risks for HIV infection among men and women receiving sexually transmitted infection clinic services in Cape Town, South Africa

OBJECTIVE

To examine the association of alcohol use and sexual risks for HIV infection in South Africa.

METHOD

149 men and 78 women receiving sexually transmitted infection (STI) clinic services in Cape Town, South Africa, completed measures of demographic characteristics, sexual behaviors, HIV risk reduction skills and substance use, including global measures (e.g., Alcohol Use Disorders Identification Test [AUDIT]) and situational measures of alcohol use.

RESULTS

52% of men (n = 72) and 17% of women (n = 13) indicated problem drinking (AUDIT score > or = 9). Problem drinking was associated with greater numbers of sex partners in the past month, history of condom failures and lifetime history of having an STI, as well as lower rates of practicing risk reduction skills. In a separate analysis controlling for global use of alcohol indexed by AUDIT scores, we found that alcohol use in sexual contexts was associated with greater numbers of sex partners, higher rates of unprotected intercourse and condom failures.

CONCLUSIONS

Findings from this initial study of alcohol use and sexual risks in South Africa parallel those from other countries in sub-Saharan Africa. Although limited to STI clinic patients, the results suggest that effective HIV risk reduction interventions will require attention to alcohol use, particularly among South Africans at highest risk for HIV infection.

Traditional beliefs about the cause of AIDS and AIDS-related stigma in South Africa

AIDS-related stigmas are pervasive in some segments of South African society and stigmas can impede efforts to promote voluntary counselling and testing and other HIV-AIDS prevention efforts. The current study examined associations among the belief that AIDS is caused by spirits and supernatural forces, AIDS-related knowledge and AIDS-related stigmas. A street intercept survey with 487 men and women living in a Black township in Cape Town, South Africa showed that 11% (n=54) believed that AIDS is caused by spirits and supernatural forces, 21% (n=105) were unsure if AIDS is caused by spirits and the supernatural, and 68% (n=355) did not believe that AIDS is caused by spirits and supernatural forces. Multiple logistic regression analyses controlling for participant age, gender, years of education and survey venue showed that people who believed HIV-AIDS is caused by spirits and the supernatural demonstrated significantly more misinformation about AIDS and were significantly more likely to endorse repulsion and social sanction stigmatizing beliefs against people living with HIV-AIDS. However, nearly all associations between beliefs that AIDS is caused by spirits and AIDS stigmas were non-significant when logistic regressions were repeated with AIDS-related knowledge included as a control variable. This finding suggests that relationships between traditional beliefs about the cause of HIV-AIDS and AIDS stigmas are mediated by AIDS-related knowledge. AIDS education efforts are urgently needed to reach people who hold traditional beliefs about AIDS to remedy AIDS stigmas.

The relationship between indicators of sexual compulsivity and high risk sexual practices among men and women receiving services from a sexually transmitted infection clinic

Sexual compulsivity, defined by sexual preoccupation and lack of sexual impulse control, is related to high-risk sexual behaviors. However, little is known about the prevalence and predictors of sexual compulsivity in people at high risk for contracting sexually transmitted infections (STIs). In the current study, patients receiving diagnostic and treatment services (85% African American) at an urban STI clinic completed measures of demographic characteristics, sexual compulsivity, substance use, and sexual behaviors. Measures were administered to 492 men and 193 women using confidential procedures and audio computer-assisted interviewing technology. Results showed that men and women receiving STI clinic services frequently endorsed multiple indicators of sexual compulsivity. In this mostly African American sample, individuals with scores above the 80th percentile on the sexual compulsivity scale (translating to over one standard deviation above the mean) had more sex partners, engaged in higher rates of sexual risk behaviors with casual or one-time sex partners, and were nearly four times as likely to have been recently diagnosed with multiple STIs than were individuals who scored below the 80th percentile. Although sexual compulsivity scores were associated with alcohol and other drug use, associations between sexual compulsivity and sexual risks were not accounted for by substance abuse. Findings suggest an urgent need for interventions to help men and women with sexual preoccupations and poor sexual impulse control to reduce their risks for sexually transmitted infections.

Sexual exposure to blood and increased risks for heterosexual HIV transmission in Cape Town, South Africa

A total of 224 men and 276 women living in a Black township in Cape Town, South Africa, were interviewed using a structured questionnaire. Information was elicited on demographic characteristics and sexual behaviours over the three months preceding the interview including engaging in sexual contact that involved blood, lifetime history of STI diagnoses and STI symptoms, and HIV prevention knowledge. Thirty six per cent of the men and 28% of women experienced sexual contact involving blood in the past three months Sexual blood contact was associated with the number of sex partners, unprotected intercourse and sexually transmitted infections. Sexual exposure to blood is prevalent and may be a facilitating factor for HIV transmission in South Africa. Modern medical care providers as well as traditional healers should be encouraged to advise their clients to refrain from sexual intercourse during menstruation and other types of genital bleeding.

Adherence to antiretroviral therapy in rural persons living with HIV disease in the United States

The current study delineated patterns and predictors of adherence to antiretroviral therapy in 329 persons living with HIV disease in rural areas of 12 US states. Participants provided self-report data on patterns of HIV medication adherence, reasons for missing medication doses, psychological symptomatology, life-stressor burden, social support, ways of coping, coping self-efficacy, the quality of their relationship with their main physician, and barriers to health care and social services. Based on adherence data collected via retrospective, self-report assessment instruments, only 50% of participants adhered consistently to antiretroviral therapy regimens in the past week. Consistent adherence was more common in White participants, persons who had progressed to AIDS, and 'native infections' (i.e. persons who were born, raised, and infected in their current place of residence). Logistic regression analyses indicated that consistent adherence was reported by persons who drank less alcohol, had a good relationship with their main physician, and engaged in more active coping in response to HIV-related life stressors. As the number of rural persons living with HIV disease continues to increase, research that identifies correlates of non-adherence and conceptualizes approaches to optimize adherence in this group is urgently needed.

HIV testing attitudes, AIDS stigma, and voluntary HIV counselling and testing in a black township in Cape Town, South Africa

OBJECTIVES

A cornerstone of HIV prevention in South Africa is voluntary HIV antibody counselling and testing (VCT), but only one in five South Africans aware of VCT have been tested. This study examined the relation between HIV testing history, attitudes towards testing, and AIDS stigmas.

METHODS

Men (n = 224) and women (n = 276) living in a black township in Cape Town completed venue intercept surveys; 98% were black, 74% age 35 or younger.

RESULTS

47% of participants had been tested for HIV. Risks for exposure to HIV were high and comparable among people tested and not tested. Comparisons on attitudes toward VCT, controlling for demographics and survey venue, showed that individuals who had not been tested for HIV and those tested but who did not know their results held significantly more negative testing attitudes than individuals who were tested, particularly people who knew their test results. Compared to people who had been tested, individuals who were not tested for HIV demonstrated significantly greater AIDS related stigmas; ascribing greater shame, guilt, and social disapproval to people living with HIV. Knowing test results among those tested was not related to stigmatising beliefs.

CONCLUSIONS

Efforts to promote VCT in South Africa require education about the benefits of testing and, perhaps more important, reductions in stigmatising attitudes towards people living with AIDS. Structural and social marketing interventions that aim to reduce AIDS stigmas will probably decrease resistance to seeking VCT.

Trauma symptoms, sexual behaviors, and substance abuse: correlates of childhood sexual abuse and HIV risks among men who have sex with men

Childhood sexual abuse is associated with high-risk sexual behavior in men who have sex with men. This study examined psychological and behavioral correlates of HIV risk behavior associated with childhood sexual abuse in a sample of men who have sex with men. Men attending a large gay pride event (N = 647) completed anonymous surveys that assessed demographic characteristics, childhood sexual abuse history, symptoms of dissociation and trauma-related anxiety, borderline personality characteristics, substance use, and sexual risk behavior. Results indicated that men who have a history of childhood sexual abuse were more likely to: engage in high-risk sexual behavior (i.e., unprotected receptive anal intercourse), trade sex for money or drugs, report being HIV positive, and experience non-sexual relationship violence. Results of this study extend previous research to show that men who have sex with men and who have a history of child sexual abuse are more likely to be at high risk for HIV infection.

Emotional Distress in Nonmetropolitan Persons Living With HIV Disease Enrolled in a Telephone-Delivered, Coping Improvement Group Intervention

The study delineated depressive symptoms and modeled emotional distress in persons living with HIV disease in nonmetropolitan areas of 13 U.S. states. Participants (N=329) were enrolled in a randomized clinical trial of a telephone-delivered, coping improvement group intervention, and 60% reported moderate or severe levels of depressive symptomatology on the Beck Depression Inventory. Structural equation modeling indicated that participants who experienced more severe HIV symptomatology, received less social support, and engaged in more avoidant coping also experienced more emotional distress (a latent construct comprising depressive symptoms and emotional well-being). Greater HIV-related stigma and rejection by family led to more emotional distress, with social support and avoidant coping mediating almost entirely the effects of the former 2 variables. The model accounted for 72% of the variance in emotional distress in nonmetropolitan persons living with HIV disease.

Stress, social support, and HIV-status disclosure to family and friends among HIV-positive men and women

Patterns of HIV-status disclosure and social support were examined among 331 HIV-positive men and women. Structured interviews assessed HIV-status disclosure to family and friends, perceived stress of disclosure, social support, and depression. Results showed patterns of selective disclosure, where most participants disclosed to some relationship members and not to others. Rates of disclosure were associated with social support. Friends were disclosed to most often and perceived as more supportive than family members, and mothers and sisters were disclosed to more often than fathers and brothers and perceived as more supportive than other family members. Path analyses tested a model of HIV-status disclosure showing that perceived stress of disclosing HIV was associated with disclosure, and disclosures were related to social support. Disclosure and its association to social support and depression varied for different relationships and these differences have implications for mental health and coping interventions.

Sensation seeking, alcohol use and sexual risk behaviors among men receiving services at a clinic for sexually transmitted infections

OBJECTIVE

Risk-prone personality dispositions are associated with alcohol use and high-risk sexual behaviors; however, the nature of these associations and their implications for sexual risk reduction interventions are not clear. This study examined a conceptual model of sensation seeking personality and alcohol expectancies as correlates of sex-related alcohol use and sexual risk behaviors.

METHOD

Men (N = 350) seeking services from an innercity clinic that treats sexually transmitted infections (STI) completed measures of demographic characteristics, sensation seeking, alcohol outcome expectancies, alcohol use in sexual contexts and sexual behaviors, administered onsite at the clinic using audio-computer-assisted interviewing.

RESULTS

Path analyses showed that sensation seeking was related to engaging in unprotected sexual intercourse with casual or one-time sex partners (i.e.,high-risk sex). Sensation seeking was also associated with stronger expectancies that alcohol use enhances sex. This association was related to alcohol use in sexual contexts which, in turn, was related to high-risk sex. Analyses also showed that alcohol outcome expectancies mediated the association between sensation seeking and alcohol use in sexual contexts.

CONCLUSIONS

Alcohol use plays important roles in risks for sexually transmitted infections, particularly among high sensation seekers. Cognitive restructuring of alcohol outcome expectancies may offer an in-road for developing HIV-STI risk reduction interventions.

Health-related Internet use, coping, social support, and health indicators in people living with HIV/AIDS: preliminary results from a community survey

Widespread Internet use has revolutionized health information and patient education for persons with chronic illnesses. The authors surveyed 147 HIV-positive persons to examine factors associated with Internet use and associations between Internet use and health. Information, motivation, and behavioral skills associated with using the Internet were related to Internet use. The authors found that health-related Internet use was associated with HIV disease knowledge, active coping, information seeking coping, and social support among persons who were using the Internet. These preliminary findings suggest an association between using the Internet for health-related information and health benefits among people living with HIV/AIDS, supporting the development of interventions to close the digital divide in HIV/AIDS care.

Sensation seeking and alcohol use as markers of sexual transmission risk behavior in HIV-positive men

Alcohol use and sensation-seeking personality characteristics are commonly associated with sexual risk behavior in populations at risk for HIV infection. However, these associations are not well understood and have not yet been examined in people living with HIV-AIDS. We used path analyses to test a model of sensation seeking, alcohol use expectancies, and sexual risk behaviors among 197 HIV seropositive men. Results showed that alcohol use outcome expectancies and alcohol used in sexual contexts were closely associated with unprotected intercourse and that sensation seeking was significantly related to alcohol use expectancies. Sensation seeking did not mediate the association between alcohol use and unprotected sexual behavior. Further analyses showed that the association between sensation seeking and alcohol use in unprotected sexual contexts was accounted for by expectancies that alcohol use improves sexual performance and enhances sexual pleasure. Analyses also indicated that men living with HIV-AIDS who used alcohol in sexual contexts were characterized by greater overall frequency and quantity of drinking. Prevention interventions may be improved by tailoring them for alcohol-using HIV-infected men, particularly by challenging beliefs and expectations that alcohol enhances sexual performance and sexual pleasure.

HIV treatment adherence and unprotected sex practices in people receiving antiretroviral therapy

BACKGROUND

Poor HIV treatment adherence can result in the development of drug resistant strains of HIV and HIV positive people may transmit drug resistant virus to their sex partners.

OBJECTIVE

To examine the association between HIV treatment adherence and sexual risk behaviour practices in people living with HIV-AIDS.

METHODS

Surveys and interviews with 255 men and women living with HIV and receiving antiretroviral therapy.

RESULTS

People who were currently taking antiretroviral medications and missed at least one dose of their medications in the past week scored significantly higher on a hopelessness scale and reported more current use of marijuana. People who had been non-adherent also reported significantly more sex partners, greater rates of unprotected vaginal intercourse, and less protected sex behaviours including less protected sex with partners who were HIV negative or of unknown HIV status.

CONCLUSIONS

Associations between HIV treatment adherence and sexual transmission risk behaviours indicate the need for comprehensive and integrated health behaviour interventions for people living with HIV-AIDS.

Health-related Internet use, coping, social support, and health indicators in people living with HIV/AIDS: preliminary results from a community survey

Widespread Internet use has revolutionized health information and patient education for persons with chronic illnesses. The authors surveyed 147 HIV-positive persons to examine factors associated with Internet use and associations between Internet use and health. Information, motivation, and behavioral skills associated with using the Internet were related to Internet use. The authors found that health-related Internet use was associated with HIV disease knowledge, active coping, information seeking coping, and social support among persons who were using the Internet. These preliminary findings suggest an association between using the Internet for health-related information and health benefits among people living with HIV/AIDS, supporting the development of interventions to close the digital divide in HIV/AIDS care.

Thoughts of suicide among HIV-infected rural persons enrolled in a telephone-delivered mental health intervention

This study characterized rates and predictors of suicidal thoughts among HIV-infected persons living in rural communities of eight U.S. states. Self-administered surveys were completed by 201 HIV-infected persons living in communities of 50,000 or fewer that were located at least 20 miles from a city of 100,000 or more. All participants were clients of rural AIDS service organizations and had recently enrolled into a randomized clinical trial of a telephone-delivered, coping improvement-group intervention designed specifically for HIV-infected rural persons. At baseline, participants reported on thoughts of suicide, psychological symptomatology, life-stressor burden, ways of coping, coping self-efficacy, social support, and barriers to health care and social services. Thirty-eight percent of HIV-infected rural persons had engaged in thoughts of suicide during the past week. A logistic regression analysis revealed that participants who endorsed thoughts of suicide also reported more depressive symptoms (odds ratio [OR] = 2.19; 95% confidence interval [CI] = 1.32-3.63, p < .002), less coping self-efficacy (OR = 0.70; 95% CI = 0.56-0.88, p < .002), more frequently worried about transmitting their HIV infection to others (OR = 1.66, 95% CI = 1.14-2.40, p < .008), and experienced more stress associated with AIDS-related stigma (OR = 1.58, 95% CI = 1.07-2.35, p < .03). As AIDS prevalence rates increase in rural areas, interventions that successfully identify and treat geographically isolated HIV-infected persons who experience more frequent or serious thoughts of suicide are urgently needed.

HIV transmission risk behaviours among HIV-positive persons in serodiscordant relationships

As many as one in three persons living with HIV-AIDS continue to practise unprotected sexual intercourse and these practices often occur with HIV-negative or unknown HIV serostatus (serodiscordant) partners. The current study examined the rates of HIV transmission risk behaviours in non-regular (e.g. casual) and regular (e.g. steady) serodiscordant relationships. HIV positive men (n = 269) and women (n = 114) responded to measures of demographic characteristics, health and mental health status, and sexual behaviours assessed in partner-by-partner interviews. 257 (67%) participants were sexually active in the preceding three months and 182 (71%) of the sexually active persons had engaged in vaginal or anal intercourse with serodiscordant partners. Comparisons of persons with non-regular (n = 97) and regular (n = 85) serodiscordant partners showed that overall rates of unprotected and protected intercourse were greater with regular partners than non-regular partners. Disclosure of HIV status to regular and non-regular serodiscordant partners did not appear to influence the pattern of results. Mathematical modelling showed that HIV transmission estimates over a one-year horizon were significantly greater for male regular partners of HIV-positive men than non-regular partners and there was a trend toward greater HIV transmission rates from HIV-positive men to their regular serodiscordant female partners compared to non-regular partners. Results suggest an urgent need for HIV transmission risk reduction interventions for HIV serodiscordant couples, particularly for couples in established, regular relationships.

Closing the digital divide in HIV/AIDS care: development of a theory-based intervention to increase Internet access

Advances in information technology are revolutionizing medical patient education and the Internet is becoming a major source of information for people with chronic medical conditions, including HIV/AIDS. However, many AIDS patients do not have equal access to the Internet and are therefore at an information disadvantage, particularly minorities, persons of low-income levels and individuals with limited education. This paper describes the development and pilot testing of a workshop-style intervention designed to close the digital divide in AIDS care. Grounded in the Information-Motivation-Behavioral Skills (IMB) model of health behaviour change, we developed an intervention for persons with no prior history of using the Internet. The intervention included instruction in using hardware and search engines, motivational enhancement to increase interest and perceived relevance of the Internet, and skills for critically evaluating and using health information accessed via the Internet. Participants were also introduced to communication and support functions of the Internet including e-mail, newsgroups and chat groups. Pilot testing demonstrated feasibility, acceptability and promise for closing the digital divide in HIV/AIDS care using a relatively brief and intensive theory-based intervention that could be implemented in community settings.

Emotional adjustment in survivors of sexual assault living with HIV-AIDS

This study examined history of sexual assault in 357 men and women living with HIV-AIDS. Participants completed measures of demographic characteristics, sexual assault history, emotional distress and psychiatric symptoms, substance use, and sexual behaviors. Results showed that 68% of women and 35% of men living with HIV-AIDS reported a history of sexual assault since age 15. History of sexual assault was related to history of substance use and mental health treatment. Sexual assault survivors reported greater anxiety, depression, and symptoms of borderline personality and were significantly more likely to report recent unprotected intercourse than persons who had not been sexually assaulted. Results suggest tailoring secondary prevention interventions to meet the needs of HIV-positive survivors of sexual assault.

Behavioral research in HIV/AIDS primary and secondary prevention: recent advances and future directions

Great advances have been made over the past decade in behavioral research on how to help persons avoid contracting HIV infections (primary prevention) and how to reduce or alleviate adverse consequences among persons who are living with HIV disease (secondary prevention). Within the primary prevention areas, research has shown the effectiveness of risk-reduction interventions undertaken with individuals, couples, small groups, communities, and at a social policy/structural level. Advances in HIV medical care have also created important new challenges and roles for behavioral scientists in the area of HIV secondary prevention. This article concludes by identifying key emerging issues in HIV behavioral research that will require attention in the years ahead.

Sexual transmission risk perceptions and behavioural correlates of HIV concentrations in semen

HIV transmission risk behaviours are related to perceived infectiousness and HIV-positive men who have undetectable blood viral loads may practise less protective behaviours. The current study extends previous research by reporting the association between perceived HIV transmission risks, risk behaviours and viral load in semen. Results showed significant associations between perceived risks for transmitting HIV, unprotected intercourse and viral load in semen. Further analyses showed that men with greater concentrations of HIV in their semen were practising higher rates of transmission risk behaviours while perceiving less risk for potentially transmitting HIV. We conclude that behavioural interventions are needed for HIV-positive men to inform them that HIV infectiousness cannot be inferred from peripheral blood viral loads and to support maintenance of HIV risk reduction behaviours.

Perceptions of health care among persons living with HIV/AIDS who are not receiving antiretroviral medications

Antiretroviral medications are effective at improving the health and increasing the survival of people living with HIV/AIDS. However, studies have shown that a substantial number of HIV-infected people do not receive antiretroviral treatments. The current study examined the physical and mental health, substance use, and perceptions of medical care of 163 men and 78 women living with HIV/AIDS. Results of a confidential survey showed that 79 (33%) were not currently treated for HIV. These persons did not differ from those who were treated in chart-abstracted CD4 cell counts, years living with HIV infection, HIV-related symptoms, and HIV-related hospitalizations. Unlike past studies, gender was not found to be a factor in treatment status. However, untreated persons had higher chart-abstracted viral loads and were more likely to be ethnic minorities, have a lower level of education, greater level of depression, and greater pessimistic attitude. They were significantly more likely to have used alcohol, powder cocaine, and crack cocaine in the previous 3 months, were likely to know their own viral load and CD4 count, and held significantly more negative views of their health care and their health care providers. There were no differences between untreated and treated persons in their meeting the year 1999 antiretroviral treatment guidelines that were in effect at the time of data collection. These results suggest that persons who are not receiving antiretroviral medications may be in need of mental health and substance use interventions and may benefit from interventions designed to engage and retain them in medical treatment.

Sex-related alcohol expectancies predict sexual risk behavior among severely and persistently mentally ill adults

Three hundred three adults (57% male, average age 42 years) with severe and persistent mental illness receiving treatment at community mental health clinics completed a survey, which included B. C. Leigh's (1990) sex-related alcohol expectancy scale and measures of alcohol use and sexual risk behavior. Hierarchical logistic regression analyses, controlling for drinking behavior, revealed that participants with stronger expectancies that drinking would lead to enhanced sexual experience were more likely to have drank prior to intercourse and that, among participants who drank prior to intercourse, those with stronger expectancies that alcohol would lead to riskier sexual behavior were more likely to have engaged in sexual risk behavior. Implications for preventing HIV infection among people with severe mental illness are discussed.

Prospective study of emotional reactions to changes in HIV viral load

Advances in antiretroviral therapies for HIV infection have given rise to new hope for the long-term survival of people living with HIV/AIDS. The current study examined changes in depression, anxiety, and HIV treatment attitudes that may co-occur with improvements and setbacks in HIV disease progression in a prospective cohort of 166 HIV-positive men and women. Results from a 9-month prospective observation period showed that persons who experienced increases in viral load, as indexed by medical chart abstraction, reported modest increases in depression and decreases in positive attitudes toward HIV treatments. Persons who experienced substantive decreases in viral load to undetectable levels demonstrated meaningful reductions in depression, particularly affective symptoms of depression after statistically controlling for years living with HIV, HIV symptoms, and age. Results suggest that emotional distress and perceptions of HIV treatments change in parallel to markers of HIV disease progression, especially with regard to reduced emotional distress in response to clinically significant changes in viral load.

Internet use among people living with HIV/AIDS: association of health information, health behaviors, and health status

The telecommunications revolution provides open access to health information that can inform and empower people living with chronic illnesses. However, many people living with HIV may not access the Internet and are not benefiting from available health information. This study investigated Internet access among people living with HIV/AIDS and its relation to health. Results of a survey of men (n = 175) and women (n = 84) living with HIV/AIDS recruited from infectious disease clinics and community-based AIDS services showed that 51% (n = 116) of participants reported ever using the Internet, of which 59% (n = 68) had used the Internet to access health-related information. As expected, Internet users were significantly more likely to be better educated and of higher incomes. Internet users, including those who used the Internet for general purposes and those who reported health-related use, also demonstrated significantly greater knowledge of HIV disease and greater confidence in their ability to adhere to medications. Persons who used the Internet for general purposes were more likely to have an undetectable viral load compared to persons who had not used the Internet. The disparities in Internet use identified in this study suggest that individuals who access the Internet, particularly for health information, are among the better resourced and healthier persons living with HIV/AIDS.

Internet access and Internet use for health information among people living with HIV-AIDS

Widespread access to the Internet has the potential to improve the health care and quality of life of people with chronic illnesses, including people living with HIV-AIDS. However, the Internet is not equally accessible to all persons. We surveyed 96 men and 51 women living with HIV-AIDS regarding their experiences using the Internet. Results showed that persons with 12 or fewer years of education were significantly less likely to have used the Internet and were less likely to have been instructed in Internet use. A broad range of health-related Internet activities was reported including searching for health, AIDS-specific information, and using the Internet to communicate with providers. Among current Internet users, individuals who had an Internet connection in their home reported significantly more experiences using the Internet, including Internet use for interpersonal communication and search functions. A digital divide therefore exists among people living with HIV-AIDS, and the benefits of the Internet appear better achieved with home access.

Substance-abusing adolescents at varying levels of HIV risk: psychosocial characteristics, drug use, and sexual behavior

PURPOSE

To evaluate the relationship of various psychosocial factors on HIV sexual risk behavior in a sample of 169 "inner city" male and female adolescents mandated into in court-ordered substance abuse treatment.

METHOD

The Millon Adolescent Clinical Inventory (MACI) and measures of sexual behavior, condom attitudes and skills, HIV knowledge, and substance abuse were administered. Data were evaluated according to five HIV risk groups: abstinent (n = 37); monogamous and practicing only protected sex (n = 19); monogamous and practicing unprotected sex (n = 45); multiple partners and practicing only protected sex (n = 11); and multiple partners and having only unprotected sex (n = 57).

RESULTS

Significant main effects were found for impulsive propensity, submissiveness, marijuana and alcohol use, condom attitudes, and intentions to engage in safer sex. Protective behavior was directly associated with submissiveness and inversely associated with impulsive personality profiles, with increased marijuana use emerging as a significant predictive factor in the choice for sexual activity vs. abstinence. More alcohol use was predictive of choosing multiple partners vs. monogamy.

IMPLICATIONS

Factoring risk variation into the design of HIV psychosocial research may enhance the tailoring of effective prevention strategies.

Human immunodeficiency virus in semen and plasma: investigation of sexual transmission risk behavioral correlates

Risks for sexually transmitted HIV may be related to concentrations of virus detected in semen and previous research shows a small to moderate association between viral load in blood and semen. This study examined the association between viral load in semen and plasma in a community sample of HIV-infected men and is the first study to examine semen viral load in relation to sexual transmission risk behaviors. A sample of 44 HIV-positive men recruited from community service agencies provided semen, blood, and urine samples and completed clinical interviews assessing health and behavior. We failed to find an association between viral load in semen and plasma, Spearman rho = 0.07, p > 0.1. When restricted to participants with detectable virus in semen and plasma, the correlation remained nonsignificant, rho = -0.16, p > 0.1. Men who had higher semen viral loads relative to their plasma viral load were distinguished by having engaged in significantly higher rates of unprotected intercourse as the insertive sex partner in the previous 3 months. Semen viral load was not, however, related to recent or current sexually transmitted infections (STIs). This study is among the first to examine sexual transmission risk behaviors as marker for HIV infectiousness. Results caution against inferring sexual transmission infectiousness based on plasma viral load and suggest that HIV-positive men who practice higher rates of insertive intercourse may be more infectious even in the absence of other STIs.

Anticipated psychological impact of receiving medical feedback about HIV treatment outcomes

Two hundred and seven persons taking antiretroviral HIV medications rated anticipated affective responses to two vignettes depicting different medical feedback situations. Participants were randomly assigned to a medical feedback vignette which varied between participants by (a) the direction of HIV viral load change (increase, decrease, no change) and (b) whether or not a medication change was recommended by the physician. The first experimental vignette was always followed by a second vignette depicting a viral load decrease (indicating treatment success in suppressing the virus). A mixed 3 (viral load change) x 2 (medication change) x 2 (within-subjects factor) factorial design was used. Significant differences in anticipated affective responses to treatment outcome situations were found, suggesting feedback about success or failure of treatment regimens impacts psychosocial adjustment of persons living with HIV.

HIV risk behaviour among men who have sex with men in public sex environments: an ecological evaluation

Men who have sex with men (MSM) in public sex environments (PSE) may be at high risk for HIV/AIDS. The majority of research on HIV risk behaviour among MSM has been conducted in open access venues more likely to be linked to networks that openly endorse preventive messages and safer sex norms. This study investigated risk practices among MSM in a PSE in order to develop effective prevention intervention strategies. Three outreach workers with previous MSM prevention experience trained in ethnographic and fieldwork observation techniques provided direct observation data. Seventy-seven observations, each lasting a minimum of two hours, were conducted over a five-month period at three city public parks. Of 614 men observed, over 250 exhibited activities and behaviours related to, or potentially related, to HIV-risk relevant sexual behaviour. Direct sexual contact between two or more men was observed 19 times, while men entering or leaving a sex area of the park was observed 66 times. Outreach workers were able to interact directly with 72 MSM, primarily discussing safer sex strategies. Sexual encounters occurred in more open areas of the PSE with partners migrating to secluded areas for intense and sexual interactions. Future prevention interventions will need to be tailored, and targeted, to specific sexual exchange access points in PSE.

Effectiveness of an intervention to reduce HIV transmission risks in HIV-positive people

BACKGROUND

As many as one in three HIV-positive people continue unprotected sexual practices after learning that they are HIV infected. This article reports the outcomes of a theory-based intervention to reduce risk of HIV transmission for people living with HIV infection.

METHODS

Men (n=233) and women (n=99) living with HIV-AIDS were randomly assigned to receive either (1) a five-session group intervention focused on strategies for practicing safer sexual behavior, or (2) a five-session, contact-matched, health-maintenance support group (standard-of-care comparison). Participants were followed for 6 months post-intervention.

RESULTS

The intervention to reduce risk of HIV transmission resulted in significantly less unprotected intercourse and greater condom use at follow-up. Transmission-risk behaviors with non-HIV-positive sexual partners and estimated HIV transmission rates over a 1-year horizon were also significantly lower for the behavioral risk-reduction intervention group.

CONCLUSIONS

This study is among the first to demonstrate successful HIV-transmission risk reduction resulting from a behavioral intervention tailored for HIV-positive men and women.

Sexual expression following spinal cord injury

Sexual adjustment, defined within this study as post-injury sexual views of the self, among 109 men and 86 women with spinal cord injury (SCI) was explored through cognitive adaptation theory [30]. It was predicted that cognitive adaptation constructs (i.e., personal control, optimism, meaning, and self-esteem) and sexual self-esteem would be predictive of sexual adjustment. It was also hypothesized that sexual self-esteem would be predictive of sexual adjustment over and above cognitive adaptation constructs. A series of hierarchical regression models were performed with results being consistent with proposed hypotheses. Implications for rehabilitation professionals are discussed and clinical suggestions are provided.

Negative affect and sexual risk behavior: comment on Crepaz and Marks (2001)

In this commentary, the authors highlight the findings of the meta-analysis by N. Crepaz and G. Marks (2001). The role of affect in sexual risk behavior, although intuitively obvious, is not well understood and has been largely ignored by HIV prevention researchers in favor of social-cognitive models of behavior. Crepaz and Marks synthesized the results from studies that have examined the relation of negative affect (e.g., depression, anxiety, anger) to sexual risk behavior and concluded that in the literature to date, these variables appear unrelated. The authors suggest that the Crepaz and Marks findings are not surprising given the methods used in the reviewed studies and suggest methodological approaches that will allow more sensitive analyses of the association between affect and sexual risk behavior.

HIV treatment adherence in women living with HIV/AIDS: research based on the Information-Motivation-Behavioral Skills model of health behavior

Close and consistent adherence to anti-HIV medication regimens is necessary to achieve the maximum benefit of these potentially effective treatments. The authors examined cognitive and behavioral factors associated with HIV treatment adherence in a convenience sample of 112 women, 72 of whom were currently taking HIV treatments at the time of the study. Women completed confidential surveys and interviews to assess HIV-related health status, treatment regimens, and cognitive behavioral characteristics derived from the Information-Motivation-Behavioral Skills model of health promotion behaviors. Results showed that women who had missed at least one dose of their HIV medications in the past week reported lower intentions (motivation) to remain adherent and lower adherence self-efficacy (skills). Structural equation modeling showed that motivational and skills-building factors significantly predicted the number of medication doses missed. However, treatment-related information did not predict treatment adherence. In addition, women who had missed a dose of medication in the past week were more likely to have ever used devices and strategies to remind them of doses, but were no more likely to currently use such strategies. Interventions that enhance treatment adherence motivation and build adherence skills may help improve HIV treatment adherence in women receiving anti-HIV therapies.

The Sexual Compulsivity Scale: further development and use with HIV-positive persons

We examined the reliability and validity of the Sexual Compulsivity Scale for use in assessing HIV-positive men and women. Measures collected from 287 men and women recruited from the community, the majority of whom were African American and over the age of 30, showed that the Sexual Compulsivity Scale was reliable for men (alpha = .89) and women (alpha = .92). Correlations with measures of sexual behaviors and numbers of sex partners supported the concurrent validity of the Sexual Compulsivity Scale for men and women. Results of discriminant function analyses that included participant age, use of nonalcohol drugs, the Sexual Compulsivity Scale, and scores on measures of trait anxiety, obsessive-compulsiveness, future pessimism, cognitive depression, and borderline personality characteristics showed that sexual compulsivity clearly discriminated between persons with 1 or no sex partners and persons with multiple partners in the past 3 months, for both men and women, suggesting evidence for criterion-related validity. Associations between sexual compulsivity scores and other markers of psychopathology showed different patterns for men and women; sexual compulsivity was associated with indexes of psychopathology in men but not in women. We conclude that the Sexual Compulsivity Scale is reliable and valid in assessing men and women infected with HIV, although sexual compulsivity may present differently between genders in relation to other forms of psychopathology.

Outcomes of a randomized small-group HIV prevention intervention trial for people with serious mental illness

HIV prevalence is alarmingly high among persons with serious mental illness and severely mentally ill adults frequently engage in high-risk behavior practices. This study evaluated the effectiveness of a small-group HIV risk reduction intervention offered to 189 men and women in outpatient programs for severely mentally ill adults. Participants screened for HIV risk were randomly assigned to attend either a 7-session small-group cognitive-behavioral HIV risk reduction intervention or a time-matched comparison intervention and were followed at 3-month intervals for one year. Participants who attended the HIV risk reduction intervention increased their condom use, had a higher percentage of intercourse occasions protected by condoms, and held more positive attitudes toward condoms. Women showed greater response to the intervention than men. While many behavior change effects were present at 3-, 6- and 9-month followup assessments, most diminished by the 12-month followup. These results under-score the need for tailored but ongoing HIV prevention efforts integrated into community programs that serve people with serious mental illness.

A pilot coping improvement intervention for late middle-aged and older adults living with HIV/AIDS in the USA

As AIDS becomes more prevalent among late middle-aged and older adults, mental health support services that facilitate the coping and adjustment efforts of this group are increasingly needed. The current article: (1) outlines a coping improvement group intervention for HIV-infected older adults; and (2) examines the efficacy of the intervention utilizing a small sample (N = 16) of older adults living with HIV/AIDS in Milwaukee, Wisconsin and New York City. The intervention focused on enabling HIV-infected older adults to accurately appraise sources of stress, develop adaptive coping responses and access social support resources to facilitate coping efforts. An evaluation of this pilot intervention, conducted using a pretest-posttest, no control group design, revealed that the intervention increased participants' perceptions of social support, produced higher perceptions of social wellbeing and enabled participants to engage in more planful problem solving, confrontive coping and future optimism. Intervention participants also experienced less stressor burden associated with AIDS-related loss and health concerns. While the current intervention showed potential to facilitate the adjustment efforts of HIV-infected older adults, randomized clinical trials of this intervention with larger samples are needed before its appropriateness for this population can be determined.
