The aim of this paper is to advance rigorous Internet-based HIV/STD Prevention quantitative research by providing guidance to fellow researchers, faculty supervising graduates, human subjects’ committees, and review groups about some of the most common and challenging questions about Internet-based HIV prevention quantitative research. The authors represent several research groups who have gained experience conducting some of the first Internet-based HIV/STD prevention quantitative surveys in the US and elsewhere. Sixteen questions specific to Internet-based HIV prevention survey research are identified. To aid rigorous development and review of applications, these questions are organized around six common criteria used in federal review groups in the US: significance, innovation, approach (broken down further by research design, formative development, procedures, sampling considerations, and data collection); investigator, environment and human subjects’ issues. Strategies promoting minority participant recruitment, minimizing attrition, validating participants, and compensating participants are discussed. Throughout, the implications on budget and realistic timetabling are identified.

Sexual Risk Taking Among Young Internet-Using Men Who Have Sex With Men

Keith J. Horvath; B. R. Simon Rosser; Gary Remafedi

OBJECTIVES We examined the characteristics of young Internet-using men who have sex with men (MSM) and risks associated with seeking sex online, offline, or through both strategies. METHODS Data were obtained from MSM aged 18 to 24 years who completed a 45-minute online survey regarding sex and Internet use in the preceding 3 months. RESULTS Significantly more Internet-using MSM who had met sexual partners both online and offline (43%) reported unprotected anal intercourse than did those who had met sexual partners exclusively online (29%) or offline (34%). MSM who met sexual partners exclusively offline reported the fewest partners but the greatest proportion of partnerships involving unprotected anal intercourse (49%). Meeting sexual partners both online and offline (odds ratio [OR]=3.38-58.42) and being drunk (OR=1.57) or high (OR=2.24) increased the odds of having more sexual partners. The same factors increased the odds of having unprotected anal intercourse (online and offline sexual partners, OR=1.60; being drunk, OR=1.43; being high, OR=1.61). CONCLUSIONS Risky sexual behavior was prevalent among all of the study subgroups. Our findings suggest that online sex seeking is associated with greater numbers of sexual partners but neither promotes nor discourages unprotected anal intercourse. Regardless of where sexual partners met, being drunk and high were significant risks for unprotected anal intercourse.

Objective:The primary objective of this study was to develop and test a highly interactive Internet-based HIV prevention intervention for men who have sex with men (MSM). MSM remain the group at highest risk for HIV/AIDS in the United States and similar countries. As the Internet becomes popular for seeking sex, online interventions to reduce sexual risk are critical. Given previous studies, a secondary objective was to demonstrate that good retention is possible in online trials. Design:A randomized controlled trial with 3-month, 6-month, 9-month, and 12-month follow-up design was employed. Methods:In 2008, 650 participants were randomized to an online, interactive sexual risk reduction intervention or to a waitlist null control. Results:Retention was 76–89% over 12 months. At 3-month follow-up, results showed a 16% reduction in reported unprotected anal intercourse risk among those in the treatment condition versus control [95% confidence interval (95% CI) of rate ratio: 0.70–1.01]. No meaningful differences were observed at 12-month follow-up. Conclusion:Internet-based, persuasive computing programs hold promise as an effective new approach to HIV prevention for MSM, at least in the short term. Further, online trials can be conducted with acceptable retention provided strong retention protocols are employed. Four directions for future research are identified.

The Internet and other new media have changed how men who have sex with men (MSM) find and interact with sexual partners. This social phenomenon, paired with growing evidence that use of the Internet increases MSM’s risk for HIV infection, makes it crucial that innovative technology-based HIV prevention interventions are developed for this population. In this commentary we explain why technology-based HIV prevention interventions are urgently needed; we then highlight findings from some of the first Internet-based HIV prevention for MSM studies that show the potential for future interventions; we next discuss ways for interventionists to conceptualize new media as a tool for HIV prevention; and finally we discuss emerging trends for technology-based HIV-prevention research.

Compulsive Sexual Behavior and Risk for Unsafe Sex Among Internet Using Men Who Have Sex with Men

Eli Coleman; Keith J. Horvath; Michael H. Miner; Michael W. Ross; Michael Oakes; B. R. Simon Rosser

The present study explored the relationship between compulsive sexual behavior (CSB) and unprotected anal intercourse (UAI) for men who have sex with men (MSM) across a number of ethnic/racial groups and who used the Internet to seek sexual partners. A sample of 2,716 MSM (512 Asian, 445 Black, 683 Latino, 348 Other, 728 White) completed on online survey that collected information about their sexual behaviors with partners met online and offline. The survey also included the Compulsive Sexual Behavior Inventory (CSBI). Consistent with the notion that CSB is a stable trait, higher scores on the CSBI were associated with greater odds for engaging in UAI, regardless of the context in which sex partners were met (online or offline). Differences in median CSB scores were generally similar across racial and ethnic groups. The median CSB score was significantly higher for HIV-positive participants than for HIV-negative participants. HIV-prevention interventions are needed among MSM, but should take into account that some may be resistant to risk reduction strategies because of CSB.

Sexual Negotiation and HIV Serodisclosure among Men who Have Sex with Men with Their Online and Offline Partners

Keith J. Horvath; J. Michael Oakes; B. R. Simon Rosser

The aim of this study was to examine online profile and in-person communication patterns and their associations with unprotected anal intercourse (UAI) in online and offline partnerships between men who have sex with men (MSM) who have never tested for HIV (“Never Tested”), had been tested at least once for HIV (“Tested”), and had tested positive for HIV. Between September and November 2005, 2,716 MSM participated in a one-time online survey. Although 75% and 72% of the Tested and Never Tested groups disclosed a HIV-negative status in all of their online profiles, 17% of HIV-positive participants did so. Exchanging HIV status information was highest among the Tested group, while HIV-positive men were most likely to negotiate UAI. Serodisclosure was not an independent predictor of UAI, although making an explicit agreement to engage in UAI was. Sexual communication and risk-taking patterns differed by testing status. Explicit agreements to avoid UAI were associated with reduced sexual risk-taking. Misrepresentation of HIV status is an identified challenge for HIV prevention.

Predictors of HIV disclosure to secondary partners and sexual risk behavior among a high-risk sample of HIV-positive MSM: results from six epicenters in the US

B. R. Simon Rosser; Keith J. Horvath; Laura A. Hatfield; John L. Peterson; Scott M. Jacoby; A. Stately

Abstract This study sought to identify predictors of HIV disclosure and serodiscordant unprotected anal intercourse (SDUAI) among HIV-positive men who have sex with men (MSM). Between January 2005 and April 2006, 675 HIV-positive MSM were recruited into the Positive Connections intervention trial held in six US cities with intentional over-sampling of HIV-positive MSM of Color (74%) and men engaging in unprotected anal intercourse (UAI) in the previous year. Baseline survey data showed 30 and 31%, respectively, of participants disclosed to none or some of their secondary sex partners in the last 90 days. Greater disclosure to secondary partners was associated with having fewer sexual partners, being extremely out as MSM, longer HIV diagnosis, knowledge of CD4 count, detectable viral load and being white. Disclosure to all secondary partners was associated with lower SDUAI. Recommendations for prevention for HIV-positive MSM include the promotion of serodisclosure to all secondary partners and increasing comfort with, and outness about, ones sexuality.

Should it be illegal for HIV-positive persons to have unprotected sex without disclosure? An examination of attitudes among US men who have sex with men and the impact of state law.

Keith J. Horvath; Richard Weinmeyer; Simon Rosser

Abstract The aims of this study were to describe the overall pattern and predictors of attitudes toward criminalizing unprotected sex without disclosure by persons living with HIV among a broad sample of men who have sex with men (MSM) living in the USA, and to examine whether attitudes and sexual risk behavior differ by states with HIV-specific laws or no such laws. Participants (n=1725) were recruited in a 3.5 month period to complete a cross-sectional 70-minute online survey assessing attitudes and high risk sexual behavior. Participants self-identified as male, 18 years of age or older, a US resident, and having ever had sex with a man. In addition, participants were coded as residing in a state with HIV-specific laws or not. Results showed that most (65%) respondents believed it should be illegal for persons living with HIV to have unprotected sex without disclosure. However, among the total sample and HIV-positive MSM, attitudes and unprotected sex with recent partners did not vary by state law. Believing that it should not be illegal for persons living with HIV to have unprotected sex without disclosure was associated with HIV-positive status (OR=0.33), higher education (ORs=0.42–0.64), gay orientation (non-gay orientation: OR=1.54), perceptions that state residents were somewhat or very accepting toward homosexuality (OR=0.75), unprotected anal intercourse with two or more recent sexual partners (OR=0.72), and lower perceptions of responsibility (OR=0.75). The results did not support the proposition that HIV-specific laws deter high-risk sexual behavior, however further research is needed to examine whether they act as a barrier for MSM at highest risk for acquiring or transmitting HIV.

A Comparison of Mental Health, Substance Use, and Sexual Risk Behaviors Between Rural and Non-Rural Transgender Persons

Keith J. Horvath; Alex Iantaffi; Rebecca Swinburne-Romine; Walter Bockting

The aim of this study was to compare the mental health, substance use, and sexual risk behaviors of rural and non-rural transgender persons. Online banner advertisements were used to recruit 1,229 self-identified rural and non-rural transgender adults (18+ years) residing in the United States. Primary findings include significant differences in mental health between rural and non-rural transmen; relatively low levels of binge drinking across groups, although high levels of marijuana use; and high levels of unprotected sex among transwomen. The results confirm that mental and physical health services for transgender persons residing in rural areas are urgently needed.

Online social media and mobile technologies hold potential to enhance adherence to antiretroviral therapy (ART), although little is known about the current use of these technologies among people living with HIV (PLWH). To address this gap in understanding, 312 PLWH (84% male, 69% White) US adults completed an online survey in 2009, from which 22 persons accepted an invitation to participate in one of two online focus groups. Results showed that 76% of participants with lower ART adherence used social networking websites/features at least once a week. Their ideal online social networking health websites included one that facilitated socializing with others (45% of participants) and ones with relevant HIV informational content (22%), although privacy was a barrier to use (26%). Texting (81%), and to a lesser extent mobile web-access (51%), was widely used among participants. Results support the potential reach of online social networking and text messaging intervention approaches.
