RESUMEN

BACKGROUND: The HIV epidemic continues to expand among men who have sex with men (MSM) in China. The NIMH Project Accept/HPTN 043 trial suggested a borderline significant trend toward HIV incidence reduction among persons with higher testing rates. METHODS: We assessed HIV testing histories and infection status among a community-based Beijing MSM. HIV serostatus was lab confirmed. We ascertained demographic/behavioral factors through questionnaire-based interviews. Associations of previous HIV testing with odds of current HIV infection were assessed, seeking improved like-with-like risk comparisons through multivariable logistic regression analysis with propensity score adjustment and restricted cubic spline modeling. RESULTS: Among 3588 participants, 12.7% were HIV infected; 70.8% reported having ever tested for HIV. Compared with MSM who never tested, those ever testing had a 41% reduction in the odds of being HIV positive [adjusted odds ratio (aOR): 0.59; 95% confidence interval (CI): 0.48 to 0.74. Higher HIV testing frequencies were associated with a decreasing trend in the odds of being infected with HIV vs. a referent group with no previous testing [>6 tests (aOR: 0.27; 95% CI: 0.18 to 0.41); 4-6 (aOR: 0.55; 95% CI: 0.39 to 0.78); 2-3 (aOR: 0.61; 95% CI: 0.45 to 0.82); P for trend <0.001]. The multivariable-adjusted model with restricted cubic spline of HIV testing frequency showed a higher frequency of previous HIV testing associated with lower odds of HIV infection, particularly among men with ≥10 lifetime male sexual partners. CONCLUSIONS: Using risk probability adjustments to enable less biased comparisons, frequent HIV testing was associated with a lower HIV odds among Chinese MSM.

RESUMEN

BACKGROUND: Individuals with severe mental illnesses (SMI) are disproportionately vulnerable to HIV infection but are not consistently engaged in HIV-related services. OBJECTIVE: To understand factors influencing implementation of HIV-related services to individuals with SMI, we conducted a series of focus groups with multidisciplinary clinicians and staff serving individuals with SMI in outpatient, emergency, acute inpatient, and chronic inpatient levels of care. METHOD: Six focus groups with 30 participants were conducted, audiotaped, and transcribed. Our qualitative analysis drew on Grounded Theory. Using NVivo Version 9, coding was conducted by the first and senior authors; interrater reliability was verified by running Coding Comparison queries. RESULTS: The providers' narratives highlighted (1) patient-related factors, (2) stigma, and (3) administrative factors as themes particularly relevant to the delivery of HIV-related services to individuals with SMI. The reported relevance of these factors ranged across levels of care, from creating multiple barriers in the outpatient care to relatively seamless and effective delivery of full continuum of HIV-related services in the chronic inpatient environment, where adequate structural support is provided. CONCLUSION: Providers' narratives suggest that effective delivery of HIV-related services for individuals with SMI requires sustained structural support that is coordinated across levels of psychiatric care and tailored to individual patient's needs. The narratives also suggest that such support is currently not available.

RESUMEN

BACKGROUND: Early antiretroviral therapy (ART) initiation is crucial to achieve HIV viral suppression and reduce transmission. HIV-infected Chinese men who have sex with men (MSM) were less likely to initiate ART than other HIV-infected individuals. We assessed predictors of ART initiation among Chinese MSM. METHODS: In 2010-2011, a cross-sectional study was conducted among MSM in Beijing, China. We examined ART initiation within the subgroup who were diagnosed with HIV infection prior to participation in the survey. Logistic regression models were fitted to evaluate socio-demographic and behavioral factors associated with ART initiation. The eligibility criterion in the 2010/2011 national HIV treatment guidelines was CD4 cell count <350 cells/µL or World Health Organization (WHO) clinical stage III/IV. RESULTS: Of 238 eligible HIV-infected participants, the median duration of HIV infection was 15 months (range: 31 days-12 years); 62 (26.1 %) had initiated ART. Among 103 men with CD4 counts <350 cells/µL, 38 (36.9 %) initiated ART. Being married to a woman (adjusted odd ratios [aOR]: 2.50; 95 % confidence interval [CI]: 1.07-5.87), longer duration of HIV infection (aOR: 10.71; 95 % CI: 3.66-31.32), and syphilis co-infection (aOR: 2.58; 95 % CI: 1.04-6.37) were associated with a higher likelihood of ART initiation. Of 135 men with CD4 count ≥350 cells/µL, 24 (18 %) initiated ART. Being married to a woman (aOR: 4.21; 95 % CI: 1.60-11.06), longer duration of HIV infection (aOR: 22.4; 95 % CI: 2.79-180), older age (aOR: 1.26; 95 % CI: 1.1-1.44), Beijing Hukou (aOR: 4.93; 95 % CI: 1.25-19.33), presence of AIDS-like clinical symptoms (aOR: 3.97; 95 % CI: 1.32-14.0), and history of sexually transmitted infections (aOR: 4.93; 95 % CI: 1.25-19.43) were associated with ART initiation. Compared with men who did not initiated ART, those with ART were more likely to receive counseling on benefits of ART (96.8 % vs. 66.4 %, P = 0 < 0.01), HIV stigma coping strategy (75.8 % vs. 65.9 %, P = 0.04), mental health (66.1 % vs. 52.9 %, P = 0.02), and substance use (46.7 % vs. 36.6 %, P = 0.04). CONCLUSIONS: We documented low rates of ART initiation among Chinese MSM. Policy changes for expanding ART eligibility and interventions to improve the continuum of HIV care are in progress in China. Impact evaluations can help assess continuing barriers to ART initiation among MSM.

RESUMEN

OBJECTIVE: To assess the correlates for bisexual behaviors, HIV knowledge, and HIV/AIDS-related stigmatizing/discriminatory attitudes among men who have sex with men (MSM). METHODS: A cross-sectional survey among MSM was conducted in 2011 to provide demographics, sexual behaviors, HIV knowledge, HIV/AIDS-related stigmatizing/discriminatory attitudes, and services in Jinan, Qingdao, and Yantai of Shandong Province of China. RESULTS: Of 1230 participants, 82.8% were single, 85.7% aged <35 years, and 47.2% received college or higher education. There were 28.6% MSM who reported to be married or cohabitating or ever had sex with woman in the past 6 months (P6M). 74.5% had ≥6 HIV-related knowledge score. The average total score of stigmatizing/discriminatory attitude was 37.4±4.4(standard deviation). Bisexual behavior was independently associated with higher levels of HIV/AIDS-related stigma/discrimination(AOR = 1.1, 95% CI:1.0-1.1), older age(AOR = 1.2, 95%CI:1.1-1.2), and lower HIV-related knowledge score(AOR = 1.6, 95%CI:1.2-2.2). HIV knowledge score ≥6 was independently associated with lower levels of HIV/AIDS-related stigma/discrimination(AOR = 1.3, 95%CI:1.2-1.3), less bisexual behaviors(AOR = 0.6, 95%CI:0.5-0.9), ever received a test for HIV in the past 12 months (P12M)(AOR = 3.2, 95%CI:2.3-4.5), college or higher level education(AOR = 1.9, 95%CI:1.4-2.6), consistent condom use with men in P6M(AOR=6.9, 95%CI:4.6-10.6), recruited from internet or HIV testing sites(AOR = 11.2, 95%CI:8.0-16.1) and bars, night clubs, or tea houses(AOR = 2.5, 95%CI:1.7-4.8). Expressing higher levels of HIV/AIDS-related stigmatizing/discriminatory attitudes was independently associated with bisexual behaviors(Aß = 0.9, 95%CI:0.4-1.4), lower HIV-related knowledge score(Aß = 3.6, 95%CI:3.0-4.1), the number of male sex partners in the past week ≥2(Aß = 1.4, 95%CI:1.0-1.9), unprotected male anal sex in P6M(Aß = 1.0, 95%CI:0.5-1.6), and inversely associated with ever received HIV test(Aß = 1.4, 95%CI:0.8-2.0) and peer education in P12M(Aß = 1.4, 95%CI:0.9-1.9). CONCLUSION: HIV/AIDS-related stigmatizing/discriminatory attitudes were associated with bisexual behaviors, low HIV testing rate, lower HIV-related knowledge and risk behaviors. This study called for innovative programs that would reduce HIV/AIDS-related stigmatizing/discriminatory attitudes and bisexual behaviors and improve the uptake of prevention service among MSM.

RESUMEN

Three consecutive cross-sectional surveys were conducted among injection drug users (IDUs). Of 2,530 participants, 47.7% reported ever sharing needles, 78.2% having had unprotected sex in the last month, 34.4% not receiving either methadone maintenance therapy (MMT) or HIV voluntary counseling and testing (VCT), 4.8% ever receiving MMT-only, 36.6% ever receiving VCT-only, and 24.2% ever receiving both MMT and VCT. MMT-only and the combination of MMT and VCT had significant associations with needle sharing and on unprotected sexual behaviors. Effectively integrating VCT into MMT services is a logical way to maximize the impact of both interventions on risky behaviors among IDUs.

RESUMEN

OBJECTIVE: This is the first study in China to examine the use of nitrite inhalants and its correlates among men who have sex with men (MSM) in Beijing, China. METHODS: A cross-sectional survey was conducted in 2012. Structured interviews collected data on demographics, sexual and drug use behaviors, and the use of HIV services. Blood specimens were collected and tested for HIV and syphilis. RESULTS: A total of 400 MSM eligible for the study were between 19 and 63 years of age and overall HIV prevalence was 6.0% (9.0% among nitrite inhalant users and 3.3% among nonusers). Nearly half (47.3%) of them reported ever using nitrite inhalants and 42.3% admitted using nitrite inhalants in the past year. Multivariable logistic analysis revealed that ever using nitrite inhalants in the past was independently associated with being aged ≤25 years, having higher education attainment, seeking sex via Internet, having casual partners in the past three months, and being HIV positive. CONCLUSION: The use of nitrite inhalants was alarmingly prevalent among MSM in Beijing. The independent association of the nitrite inhalant use with more casual sex partners and HIV infection underscored the need for intervention and prevention of nitrite inhalant use.

RESUMEN

OBJECTIVE: This research was conducted to assess the correlates of alcohol consumption and HIV/AIDS-related stigmatizing and discriminatory attitudes among men who have sex with men (MSM) in Shandong province, China. METHODS: A cross-sectional survey provided demographics, sexual behaviors, illicit drug use, alcohol consumptions, and service utilization. RESULTS: Of 1,230 participants, 82.8% were single, 85.7% aged <35 years, 47.2% had college or higher education, and 11.7% drank alcohol >3 times per week in the past six months. The average total score of stigmatizing and discriminatory attitude was 37.4 ± 4.4. More frequent episodes of alcohol use were independently associated with higher levels of HIV/AIDS-related stigma and discrimination, unprotected anal sex, bisexual identity, multiple male sex partners, drug use, and lower levels of education. Expressing higher levels of HIV/AIDS-related stigmatizing and discriminatory attitudes was independently associated with alcohol use, unprotected male anal sex, bisexuals, more male sex partners, commercial sex with men, and non-receipt of peer education in the past year. CONCLUSION: HIV/AIDS-related stigmatizing and discriminatory attitudes are common and associated with alcohol use and unprotected sex among MSM. The finding highlights the needs to develop programs that would reduce HIV/AIDS-related stigmatizing and discriminatory attitudes and strengthen alcohol use prevention and risk reduction initiatives among MSM.

RESUMEN

OBJECTIVE: To investigate factors associated with HIV infection and the frequency and willingness of male circumcision among men who have sex with men (MSM) in Chengdu city, China. METHODS: A cross-sectional survey provided information on participants' demographics, risk behaviors, circumcision, and uptake of HIV prevention services. RESULTS: Of 570 participants, 13.3% were infected with HIV and 15.9% with syphilis. An estimated 43.0% of respondents reported having unprotected receptive anal intercourse, and 58.9% reported having ≥2 male sexual partners in the past 6 months. Multivariable logistic regression revealed that syphilis, more male sex partners, predominantly receptive anal intercourse, and exclusively receptive male sex were associated with HIV infection. Higher level of education and peer education service were inversely associated with HIV infection. Nearly a fifth (18.0%) of participants were circumcised. More than half of uncircumcised participants expressed willingness to be circumcised. CONCLUSION: This study reveals a high prevalence of HIV and syphilis among MSM in Chengdu province of China. The frequency of unprotected receptive anal intercourse and multiple male sexual partnerships highlight the urgency for an effective comprehensive HIV prevention strategy. Although the willingness to accept male circumcision (MC) is high, further research is needed to assess the protective effective of MC among MSM.

RESUMEN

Washington, DC, is a metropolitan city with a severe HIV epidemic and faces challenges in retaining people living with HIV (PLWH) in quality care. This study assessed site migration in seeking care services and its correlates among PLWH in DC. PLWH diagnosed before 2008 and living through the end of 2010 were analyzed. Six scenarios of site migration were examined as patients visited =2, =3, and =4 different providers for their CD4 cell count and/or viral load (VL) tests in the past 3 years from 2008 to 2010 and 2 years from 2009 to 2010, respectively. Of 6480 patients analyzed from 2008 to 2010, 18.4% had CD4 < 200 cells/mm(3), 30.5% had VL > 400 copies/mL, and 76.6% were retained in same care sites; 23.4%, 5.0%, and 0.9% visited =2, =3, and =4 sites in the past 3 years from 2008 to 2010, respectively. Of 5954 patients analyzed from 2009 to 2010, 16.8% had CD4 < 200 cells/mm(3), 29.4% had VL > 400 copies/mL, and 81.9% were retained in same care sites; 18.1%, 3.1%, and 0.6% visited =2, =3, and =4 sites in the past 2 years from 2009 to 2010, respectively. Multivariable logistic regression analyses revealed that migration across six scenarios are consistently associated with CD4 < 200 cells/mm(3) and VL > 400 copies/mL. Site migration was common and associated with lower CD4 and higher VL among PLWH in DC. Frequent migration might be a factor in achieving optimal health outcomes for a subset of patients. Site migration might potentially limit effective delivery of high quality care and treatment services. The preliminary findings underscore the need for further research to assess the predictors of migration and its impact on stage of care.

RESUMEN

OBJECTIVE: The purpose of this review was to assess the prevalence of unprotected anal intercourse (UAI) among men who have sex with men (MSM) in China. METHODS: A comprehensive search was conducted including online databases like "Wanfang", Chinese National Knowledge Infrastructure, PubMed and manual searches. Analyses using random-effects models were performed to estimate the prevalence of UAI among MSM in China. RESULTS: Sixty-two articles reporting eighty-two studies were selected. The pooled prevalence rates of UAI with any male partner, with regular male partners, with non-regular male partners, with casual male partners, and with commercial male partners among MSM were 53%(95%CI: 51-56%), 45%(95%CI: 39-51%), 34%(95%CI: 24-45%), 33%(95%CI: 30-36%), 12% (95%CI: 5-26%), respectively. A cumulative meta-analysis found that the pooled UAI prevalence decreased over time. CONCLUSIONS: Although the prevalence of UAI with male partners among MSM in China presents a decreasing trend over the past decade, the concomitant rise in HIV prevalence and incidence indicates that current prevention intervention efforts are insufficient to effectively contain the spread of HIV. Therefore, the persistently high prevalence of risky sexual behaviors underscores the need for innovative and effective prevention strategies among MSM.

RESUMEN

OBJECTIVE: To investigate barriers and correlates of the use of HIV prevention services and HIV testing behaviors among men who have sex with men in Chongqing. METHODS: Three consecutive cross-sectional surveys provided demographic, sexual behavior, HIV/syphilis infection, HIV prevention service, and testing behavior data. RESULTS: Of 1239 participants, 15.4% were infected with HIV, incidence was 12.3 per 100 persons/year (95% CI: 9.2-15.3), 38% of the participants reported ever having unprotected insertive anal sex, 40% ever received free condom/lubricants in the past year, and 27.7% ever obtained free sexually transmitted infection examination/treatment in the past year. Multivariable logistic regression revealed that lower levels of HIV/AIDS related stigmatizing/discriminatory attitudes, full-time jobs, and sex debut with men at a younger age were independently associated with use of free condom/lubricants. Large social networks, higher incomes, and sexual debut with men at a younger age were associated with use of any HIV prevention and HIV testing services. Lower levels of stigmatizing/discriminatory attitudes were also associated with HIV testing. Fearing needles and being unaware of the venues for testing were top barriers for testing service utilization. CONCLUSION: It is imperative to address HIV/AIDS related stigmatizing/discriminatory attitudes and other barriers while delivering intervention and testing services.

RESUMEN

Current advances have added geosocial networking (GSN) mobile phone applications as an option for men who have sex with men (MSM) to meet other men. This is the first study to assess GSN application use and sex-seeking behaviors of MSM recruited using venue-based sampling. Among the 379 MSM in this study, 63.6 % reported using GSN applications to find men in the past year. Nearly one-quarter of MSM had sex with a man met using a GSN application in the prior year; these men were more likely to be under 35 years old and have had sex with a man met on the Internet; they were also less likely to be HIV-positive and have <5 male sex partners in the last year. GSN applications are a viable option for use in sampling and delivering interventions to young MSM who are often missed through other methods.

RESUMEN

This study assessed the changes of HIV incidence and its predictors among Beijing's men who have sex with men (MSM). Three consecutive cross-sectional surveys were carried out using a consistent respondent-driven sampling (RDS) approach in 2009, 2010, and 2011, respectively. Structured-questionnaire based interviews were completed with computer-assisted self-administration. Incident infection was examined with BED capture enzyme immunoassay (BED-CEIA). The overall rate of HIV prevalence was 8.0% in the three years (95% confidence interval [CI]: 4.9%-11.2%). The overall rate of BED-CEIA incidence was 7.8/100 person years (PY) (95% CI: 5.5-10.1) with 6.8/100PY (95% CI: 3.4-10.2) in 2009, 11.2/100PY (95% CI: 6.2-16.3) in 2010, and 5.8/100PY (95% CI: 2.4-9.3) in 2011, respectively. Multivariable logistic regression analysis revealed that, compared with HIV-negative MSM, recently infected MSM were more likely to be bisexual (adjusted odds ratio [AOR] = 2.1, 95% CI: 1.1-4.1), live in Beijing ≤3 years (AOR = 2.1, 95% CI: 1.2-4.0), and have a negative attitude towards safe sex (AOR = 1.1 per scale point, 95% CI: 1.0-1.1). This study demonstrated a disturbing rise of HIV infections among Beijing's MSM. These findings underscored the urgency of scaling up effective and better-targeted intervention services to stop the rapid spread of the virus.

RESUMEN

Childhood sexual abuse (CSA) has been reported to be disproportionately higher among men who have sex with men (MSM) than among heterosexual men; it has also been found to be significantly positively associated with HIV status and HIV risk factors, including unprotected anal intercourse. The purpose of this study was to assess the correlates of CSA in a sample of community-recruited MSM, investigate race as a potential effect modifier, and describe the independent association between CSA and HIV infection in Washington, DC. A total of 500 MSM were recruited by venue-based sampling in 2008 as part of the National HIV Behavioral Surveillance. More than one-half of MSM identified as White, while one-third identified as Black. CSA was reported by 17.5 % of the 451 MSM, with the first instance of abuse occurring at a median age of 8.3 (interquartile range = 5.0, 11.0). In multivariable analysis, HIV-positive men were significantly more likely to report a history of CSA compared to HIV-negative men after adjusting for intimate partner violence in the last 12 months, having been arrested in the last 12 months, and depressive symptoms. HIV-positive MSM had more than four times the odds of reporting CSA after controlling for other correlates (aOR = 4.19; 95 % CI 2.26, 7.75). Despite hypothesizing that race modified the effect of CSA on HIV infection we found this was not the case in this sample. More research is needed to investigate the potential pathway between a history of CSA and HIV infection, and how this contributes to driving the HIV epidemic among MSM in Washington, DC.

RESUMEN

BACKGROUND: An upsurge in club drug use has been observed in recent years in some cities of China, especially methamphetamine, which is quickly replacing heroin to become the most widespread drug across the nation. This study investigated the type of drugs used, syphilis and hepatitis C virus (HCV) infection and the correlates for syphilis, HCV and unprotected commercial sex behavior among drug users in two cities along the east coast of China. METHODS: A cross-sectional survey conducted in 2010 provided demographics, sexual and drug use behaviors, HIV knowledge and the utilization of intervention services among drug users. Blood samples were tested for HIV, syphilis, and HCV infection. RESULTS: Of 805 eligible participants, 0.2% were infected with HIV, 3.7% with HCV, and 9.6% with syphilis. Of the participants, 96.6% were methamphetamine users, 11.9% reported ever having used ≥2 types of these drugs, and 11.4% reported ever injecting drugs. In the multivariable logistic regression analysis, participants infected with syphilis were more likely to be female (adjusted odds ratio (AOR)=2.8, 95% confidence interval (CI): 1.2-6.5), have ever had commercial sex in the past 12 months (AOR=2.0, 95% CI: 1.0-3.9), be infected with HCV (AOR=12.1, 95% CI: 4.1-20.3) and less likely to have ever had sex with regular partners in the past 12 months (AOR=0.2, 95% CI: 0.1-0.6). Participants infected with HCV were more likely to have ever injected drugs (AOR=2.7, 95% CI: 1.1-6.5) and be infected with syphilis (AOR=8.0, 95% CI: 3.5-18.0). Participants who had unprotected sex with commercial sex partners in the last sexual encounter were more likely to be female (AOR=2.9, 95% CI:1.7-4.9), have middle school or lower level education (AOR=3.4, 95% CI:2.0-5.5), never have received intervention in the last year (AOR=2.1, 95%CI:1.2-3.6) and be infected with syphilis (AOR=4.2, 95% CI:2.4-7.4). CONCLUSIONS: Methamphetamine is the predominant drug used among the drug users, the prevalence of syphilis and HCV infection are alarmingly high, and unprotected commercial sex was common among this group. The findings highlight the need for effective, multifaceted interventions addressing sexual and drug use-related risky behaviors among this group. Further research is needed to better understand the causal pathway of the syndemics.

RESUMEN

Participation of MSM in group sex events (GSEs) is an understudied phenomenon. Studies on GSEs identified significant proportions of MSM engaging in unprotected anal intercourse (UAI). We sought to identify the prevalence of group sex participation among MSM in Washington, DC and to characterize these experiences. Data were collected for NHBS-MSM-3 in 2011. More than one-quarter of MSM (27.2 %) reported engaging in group sex in the prior year, with one-third reporting no condom use with their sex partners (33.0 %). In multivariable logistic regression, men who participated in a GSE in the prior year were significantly younger, more likely to be white, and to have used crystal meth, poppers, and downers in the past year. The high prevalence of UAI during GSEs, especially in view of the fact that HIV-positive MSM were significantly less likely to report condom use, offers an opportunity to develop risk reduction interventions specific to GSE attendees.

RESUMEN

The epidemiology of HIV in urban centers of the United States such as the District of Columbia (DC) is dynamic with rates of new HIV and AIDS diagnoses as well as risk factors elevated. Correlates of HIV among heterosexual women extend beyond traditional, individual risk factors to structural factors. The purpose of this study was to compare proportions of HIV and correlates of HIV among women participating in National HIV behavioral surveillance (NHBS) system in 2006-7 (NHBS Cycle 1) and 2010 (NHBS Cycle 2). Analysis of 677 female participants at elevated risk for HIV revealed high prevalence of individual-level HIV-associated risk factors (e.g., sexual behavior) and socio-structural associated risk factors (e.g., homelessness, incarceration, lack of health insurance). While a greater proportion of women were HIV-infected in Cycle 2, after controlling for the distribution of demographic characteristics to adjust for a change in eligibility criteria, the pooled sample did not reveal a significantly increased proportion of HIV-infected women in Cycle 2. Homelessness and condom use were associated with greater relative odds of HIV after adjustment for confounders, and non-injection drug use was associated with reduced odds. Findings inform our understanding of the continuing HIV epidemic in DC and support development of effective interventions to slow the epidemic among women in DC and similar urban centers.

RESUMEN

Social norms around condom use and safe sex as well as HIV/AIDS stigma are used to identify persons at higher risk for HIV. These measures have been developed and tested in a variety of settings and populations. While efforts have been undertaken to develop context specific measures of these domains among Chinese MSM, the feasibility of using existing measures is unknown. A survey of MSM, based on respondent-driven sampling, was conducted in Beijing. Existing measures of condom social norms, attitudes towards safer sex and HIV/AIDS stigma were piloted. Internal consistency of all measures was high. As expected higher levels of condom social norms and positive attitudes towards safer sex were associated with condom use. HIV/AIDS stigma and discrimination had a significant relationship with never having an HIV test and lack of discussion of HIV/AIDS with male partners. Correlates of low condom social norms were age, education, employment and resident status. Existing measures of condom social norms, attitudes towards safer sex and HIV/AIDS stigma appear to be appropriate for use among Chinese MSM. Using existing measures as opposed to developing new measures has the potential to expedite investigations into psychosocial correlates of HIV risk behavior.
