CAPS Town Hall Presents: Tim Lane, PhD MPH

Aggravated Homosexuality”: the (Re)Criminalization of homosexuality in Africa, and what every HIV researcher and other human being should know (12:00pm -1:00pm)

In 2014, the Presidents of Uganda and Nigeria signed into law draconian legislation that denies the basic human rights of lesbian, gay, bisexual, and transgender persons. These laws have severely impacted the ability of LGBT organizations to mobilize their communities, including for participation in HIV prevention and treatment programs. These “anti-gay” laws also have important legal and ethical implications for local and international HIV clinicians, researchers, and other public health professionals working with local LGBT communities. Dr Tim Lane will provide an overview of the deteriorating human rights situation, its impact on HIV services, and lead a discussion of how we in the United States can help (and not help) our sisters and brothers in affected countries.

Tim Lane, PhD MPH is an Associate Professor at the UCSF Center for AIDS Prevention Studies. His work with men who have sex with men (MSM) in Africa includes PEPFAR-sponsored HIV surveillance programs in Ghana, Kenya, Mozambique, and South Africa. He is the Principal Investigator of Project Boithato, an HIV prevention intervention for MSM in rural South Africa co-sponsored by NIAID and CDC-South Africa.  Dr. Lane currently serves a Co-Chair of the board of directors of the International Gay and Lesbian Human Rights Commission (www.iglhrc.org).

CAPS Town Hall Presents: Glenn-Milo Santos, PhD, MPH “Project iN” (12:00-1:00pm)

Project iN is a pilot placebo-controlled randomized trial looking at the feasibility, acceptability, and tolerability of taking a pharmacologic intervention on an as-needed basis to reduce methamphetamine use and heavy episodic alcohol consumption among MSM at high-risk for acquiring or transmitting HIV.

CAPS/TIE Core Community Town Hall Presents: Darryl Lampkin, Community Program Supervisor for the STD/HIV Program, San Mateo Public Health Division (12:00-1:00pm)

Using Mobile Apps to Encourage MSM to Get Tested for HIV and Other Sexually Transmitted Diseases

Darryl Lampkin is the Community Prevention Supervisor for the STD/HIV program at the San Mateo County Health Department.  County officials have utilized the popular online hookup application Grindr to encourage more men who have sex with men to get tested for HIV and other sexually transmitted diseases.  The outreach approach, which utilizes online profiles containing minimal information to engage with Grindr users has increased outreach numbers and has recently garnered the attention of the media, raising concerns around ethics and privacy.  Mr. Lampkin will discuss the parameters of the intervention which seek to tap into populations of MSM in San Mateo County who would otherwise remain hidden.

CAPS Town Hall Presents: Willi McFarland, MD, PhD, MPH & TM (12:00-1:00pm)

Lessons Learned with Respondent-Driven Sampling from Around the World

Populations most affected by HIV can be challenging to include in research in many parts of the world because behaviors that lead to infection are stigmatized, illegal, or both. Therefore, obtaining truly representative samples from such marginalized communities is virtually impossible, creating a major gap in data for evidence-based public health. Respondent-driven sampling (RDS) is held as the answer to this dilemma: serving both as an efficient recruitment tool and a population-based sampling methodology. However, there are many practical and theoretical challenges to RDS that call for re-examination of these claims. The presentation will focus on the theory, practice, and comparative strengths and weaknesses of RDS based on lessons learned from over 12 years of field work with RDS in Uganda, China, Tanzania, Brazil, Namibia, San Francisco, and beyond.

Willi McFarland is Professor of Epidemiology and Biostatistics at UCSF and Director of the Center for Public Health Research at the San Francisco Department of Public Health. He has worked for the past 23 years in HIV/AIDS prevention research, beginning as a resident at UCSF/UCB followed by the TAPS post-doctoral program at CAPS. He is the Principal Investigator (PI) of several HIV epidemiology research projects and prevention intervention studies in San Francisco, Africa, Asia, and Latin America. Dr McFarland’s particular area of research interest is in the methods to rigorously sample hidden and hard-to-reach populations and was recently awarded an R25 to develop and test a new sampling method (“Starfish Sampling”) for isolated minority populations.

CAPS Methods Core Presents: Lance Pollack, PhD “Conversational Interviewing vs. Standardized Interviewing: Initial Quantitative Findings from an Experiment Using a Sexual Behavior Assessment of MSM”

Abstract:       Standardized interviewing has been widely accepted as a means to reduce interviewer-related error by insuring that all participants receive the same stimulus (i.e., the same question worded the same way every time), thus leaving interpretation of the question up to the respondent. However, critics of this approach argue that response validity is undermined if all respondents do not interpret the question the same way. That is, if comprehension of the intended meaning of the question differs from participant to participant, how does the researcher know how to interpret the answers to that question? Research by Conrad and Schober have demonstrated that there is significant variation in the understanding of even seemingly straightforward questions like the number of bedrooms in one’s house and the furniture purchases made in the past year. Principal investigators Diane Binson and Bill Woods received funding for a study to test whether interviewing technique would make a difference in responses to a sexual behavior assessment. A convenience sample of currently sexually active MSM recruited primarily from Bay Area sex clubs were randomly assigned to either a standardized interviewing condition or a conversational interviewing condition and administered a sexual behavior assessment. How the experiment was implemented and initial quantitative findings will be reported.
