Supporting Statement


A. Justification

  1. Circumstances Making the Collection of Information Necessary


The Centers for Disease Control and Prevention’s (CDC) Division of HIV/AIDS Prevention, (DHAP) requests OMB approval for a qualitative extramural research study entitled, “Barriers and Facilitators to HIV Prevention, Care, and Treatment among Transgender Women in Atlanta, GA, Philadelphia, PA, and Washington, DC (T-Qual)” under the Using Qualitative Methods to Understand Issues in HIV Prevention, Care and Treatment in the United States Generic Clearance (OMB #0920-1091, expires 12/31/2018). CDC will sponsor this data collection activity. Data collection will be carried out by CDC’s contractor, Atlas Research, in conjunction with its subcontracting partner, Abt Associates.


Little research has been conducted to understand the unique complexities surrounding transgender women’s experiences related to HIV prevention, care, and treatment even though HIV incidence is higher among transgender women as compared to other populations. To effectively address the HIV epidemic in this population, more must be known and understood about the nature of transgender women’s risks for HIV infection, and what evidence-based HIV prevention, care and treatment strategies are available and can be adapted to better meet the needs of transgender women. Qualitative research provides a unique opportunity to address these gaps.

According to a 2008 systematic review of 29 studies measuring HIV prevalence among U.S. transgender populations, pooled data from four studies reporting HIV test results indicated a 28% HIV prevalence among transgender women, and data from 18 studies reporting participants’ self-reported HIV status indicated 12% HIV prevalence (Herbst et al., 2008). Furthermore, a higher proportion of African American transgender women have tested positive for HIV infection (56.3%), compared to Latina and White transgender women (Herbst, et al., 2008).


Many transgender women engage in behaviors that increase their risk for HIV infection, including having multiple sex partners, condomless receptive anal sex, alcohol and drug use, and needle exchange for recreational drugs, hormone therapy (HT) or injecting silicone (Bockting, Robinson, & Rosser, 1998; Brennan, et al., 2012; Crosby & Pitts, 2007; Nemoto, Operario, Keatley, & Villegas, 2004). Transgender women are stigmatized and ostracized by society (transphobia), which can make them extremely vulnerable to engaging in sex work and experiencing homelessness. Several studies have shown that perceptions of low risk, low educational attainment and experiencing discrimination from potential employers and society at large, may drive transgender women to engage in sex work to survive (Herbst, et al., 2008; Kosenko, 2011; Nemoto et al., 2004; Sevelius, Patouhas, Keatley, & Johnson, 2014). Along with this, studies have indicated that the need to have gender identity affirmed may lead transgender women to engage in unprotected anal sex with main partners or clients (Crosby & Pitts, 2007; Nemoto, et al., 2004; Sevelius, 2013).


Furthermore, transgender women experience multiple health care needs that are unattended such as behavioral health issues (Nuttbrock, et al., 2013), drug use and abuse (Nemoto et al., 2004; Sevelius et al., 2014), access to safe hormone therapy (Herbst et al., 2008) and antiretrovirals (ARVs) for HIV/AIDS care and treatment (Sevelius et al., 2014). These risk behaviors and unmet healthcare needs unfold in the context of stigma, social isolation, economic necessity, and violence (Herbst, et al., 2008; Kosenko, 2011; Lombardi, Wilchins, Priesing, & Malouf, 2001; Nemoto et al., 2004; Sevelius, 2013).


A study conducted by Sevelius and colleagues (2014) found that transgender women experience several barriers when attempting to engage in HIV prevention, care, and treatment including avoiding HIV testing sites that are not considered trans-friendly, avoiding medical care because of previously experienced transphobia from service providers, prioritization of hormonal treatment over ARVs, concerns about confidentiality (e.g. seeing people they know at the health clinic), drug and alcohol use, and lack of social support and mental health services. Sevelius and colleagues concluded that the single most important facilitator to engage transgender women in care was availability of gender-affirming healthcare, in which healthcare providers were educated in transgender health, and able to provide both HIV care and hormone therapy. Thus, the lack of gender-affirming healthcare was seen as a significant barrier to HIV care. To address this gap in programming, it is important that service providers address the multi-level risks and needs of transgender individuals (e.g. safe space, healthcare, mental health) (Gelaude, Sovine, Swayzer, & Herbst, 2013). Currently there is a dearth of effective HIV prevention and treatment interventions for transgender individuals (Operario & Nemoto, 2010). CDC’s Compendium of Evidence-based Interventions and Best Practices for HIV Prevention has not identified any HIV prevention interventions or best practices for transgender participants that satisfy CDC’s evidence-based criteria for efficacy (CDC, 2014). Several risk reduction interventions have been developed for transgender women (Bockting et al., 1998; Bockting, Robinson, Forberg, & Scheltema, 2005; Garofalo, Deleon, Osmer, Doll, & Harpe, 2006; Garofalo, Johnson, Kuhns, Cotten, Joseph, & Margolis, 2012; Nemoto et al., 2004; Taylor, Bimbi, Joseph, Margolis, & Parsons, 2011). However, four of the above mentioned interventions have not been rigorously evaluated and two are currently undergoing RCTs (Garofalo et al., 2012; Taylor et al., 2011).



One of the most promising prevention innovations to reduce HIV transmission rates is pre-exposure prophylaxis (PrEP) as a part of a comprehensive HIV prevention approach. The publication of Clinical Practice Guidelines for PrEP by CDC (May 2014) has highlighted an urgency to investigate circumstances that facilitate or hinder access to PrEP. Yet despite years of PrEP research, we know very little about transgender women and PrEP. Unfortunately, studies seldom include transgender women in their sample or they only include small subsamples of transgender women. For instance, a study conducted with both men who have sex with men (MSM) and transgender women on barriers and facilitators to PrEP, included 177 MSM in their sample and only seven transgender women (Golub, Gamarel, Rendina, Surace, & Lelutiu-Weinberger, 2013). Furthermore, a recent analysis of the iPrEx trial found that PrEP could be effective in preventing HIV infection among transgender women. However, transgender women (especially those who are at higher risk for HIV) experience barriers to adherence (Deutsch, et al., 2015). Additional research is needed to increase our understanding of barriers and facilitators to HIV prevention, care and treatment experienced by transgender women at an individual, interpersonal and structural level; as well as the role that their healthcare providers can play in engaging transgender women in protective behaviors.

  1. Purpose and Use of the Information Collection


The purpose of this information collection is to conduct in-depth interviews among transgender women and their healthcare providers to identify barriers and facilitators to HIV prevention, care, and treatment. The information collected through this study will also be used to improve local and national HIV prevention and/or treatment services and programs for transgender women.


The planned study design will sample 20 HIV infected and 20 HIV uninfected transgender women identified and recruited through local transgender-serving CBOs, and a small convenience sample of 10 healthcare providers referred by the transgender women participants or identified by study staff. Study instruments will include an in-depth qualitative interview with both closed and open-ended questions. Participants will be selected from three Metropolitan Statistical Areas (MSAs) with high HIV prevalence: Atlanta, GA; Philadelphia, PA; and Washington, DC. Due to potential challenges in identifying and recruiting transgender women, we anticipate that multiple sampling and recruitment strategies will be utilized to ensure an adequate number of participants.



We will use qualitative, in-depth interviews to collect data for this study (Attachments 3d-f). Interviews will include a short, structured response instrument to collect participants’ demographic information (Attachments 3b-c). The in-depth interviews will primarily include open-ended questions with some closed-ended questions designed to elicit information on HIV prevention, care and treatment among transgender women in the jurisdictions (Attachments 3d-f). Key variables to be explored through the interviews are described in Exhibit 2.1 below. All data collection instruments have been approved by the Abt Associates IRB (Attachment 4).


CDC, in partnership with the contractor staff, will identify and develop appropriate dissemination opportunities for these findings. The results of this study are not intended to be generalized to the larger population. CDC and/or its partners may also analyze these data and publish results in peer-reviewed journals. Stakeholders from the participating CBOs will also be briefed by contractor staff on the study findings (e.g., memo summarizing findings).

  1. Use of Improved Information Technology and Burden Reduction


The contractor will conduct individual interviews at a time and location that is convenient to the selected key participants. Telephone interviews or visual remote interviews (such as web or Skype interviews) are not a good vehicle for developing the necessary rapport between interviewer and respondent for a successful qualitative interview on a sensitive topic. Body language and facial cues are critical to understand where additional probing may be needed or should stop, and telephone or web interviews limit the interviewer’s ability to read both. Thus, the contractor will conduct the individual, in-depth interviews (IDIs) in person. After asking for and receiving permission from the respondent, the contractor will audio-record the interviews and transcribe recordings after the interview. This limits the burden on the respondent (no additional burden after completing the interview) and allows the interviewer to focus on building and maintaining rapport with the respondent.


  1. Efforts to Identify Duplication and Use of Similar Information


The interviews will collect key information that the Agency believes is not captured elsewhere. The Agency believes no other survey data collection effort has been conducted or has been planned to collect similar information for these populations. CDC conducted a review of similar studies prior to the issuance of the contract, and determined that this study is collecting unique information from the populations. Therefore, our evaluation requires the collection of this new primary data. There would be no reason for another Federal Agency to evaluate this.

  1. Impact on Small Businesses or Other Small Entities

This study will partner with transgender-serving community based organizations to aid in recruiting potential respondents by identifying eligible potential participants through their routine and regularly occurring activities and referring them to the study. We do not anticipate substantial burden.

  1. Consequences of Collecting the Information Less Frequently

The present study will provide the primary qualitative data needed to understand barriers and facilitators to HIV prevention, care, and treatment among transgender women at the greatest risk for HIV infection and transmission in the U.S. If this evaluation were not conducted, it would not be possible to identify barriers and facilitators and to use this information to strengthen HIV prevention, care, and treatment with these vulnerable populations. The length of data collection is 2-3 months and data will only be collected once.

  1. Special Circumstances Relating to the Guidelines of 5 CFR 1320.5


This data collection effort does not involve any special circumstances.

  1. Comments in Response to the Federal Register Notice and Efforts to Consult Outside the Agency


A 60 day FRN notice to solicit public comments was published for the Generic umbrella collection (0920-1091) in the Federal Register on 02/24/2015, Volume 80, Number 36, Page Number 9727-9728. No public comments were received.


In addition, the following contractor staffs at Atlas Research and Abt Associates were consulted for the development of this study. There were no unresolved issues associated with the consultation process. Aside from the official 60 day public comment period for the Generic data collection, there were no other public contacts or opportunities for public comment on this information collection.

  1. Explanation of Any Payment or Gift to Respondents


Interview participants will each receive a $40 token of appreciation in the form of gift cards or money orders. Although there has been some debate on the necessity of offering tokens of appreciation, numerous studies have shown that tokens of appreciation can significantly increase response rates, and the use of modest tokens of appreciation is expected to enhance survey response rates without biasing responses.1, 2


Offering tokens of appreciation is necessary to recruit minorities and historically underrepresented groups into research. In a recent study of recruitment and retention of Black men who have sex with men (BMSM) by a Community Based Organization (CBO), recruiters found it difficult to obtain information from the BMSM because many were reluctant to provide their names and contact information because of concerns about being seen giving these personal details to an HIV prevention program.3 Some of those who were screened provided incorrect contact information, making it difficult or impossible to locate them later. In this study, offering a token of appreciation improved participation among BMSM.3 A meta-analysis of 95 studies published between January 1999 and April 2005 describing methods of increasing minority persons’ enrollment and retention in research studies found that remuneration enhanced retention among this group.4


Remuneration has been used in other HIV-related CDC data collection efforts, such as for National HIV Behavioral Surveillance (OMB 0920-0770, exp. 5/31/2014) and the Testing Brief Messages for Black and Latino MSM Study (OMB 0920-14SY under 0920-0840, exp. 1/31/2019), which included similar populations and had a similar length of time for completing the client interview as in this proposed research. In all of these other projects, tokens of appreciation were used to help increase participation rates. 


  1. Protection of the Privacy and Confidentiality of Information Provided by Respondents


The NCHHSTP PRA Coordinator has reviewed this project and determined the Privacy Act does not apply since personally identifiable information (PII) will not be transmitted to the CDC.


We will inform respondents that their responses will be kept private to the extent permitted by the law. All respondents interviewed will be informed that the information collected will not be attributable directly to the respondent and will only be discussed among members of the research team. Terms of the CDC contract authorizing data collection require the contractor to maintain the privacy of all information collected. Accordingly, individuals’ data will be kept private and protected to the extent permitted by law.


In addition, the study plans to utilize a Certificate of Confidentiality to protect the privacy of respondents enrolled in the study. The certificate protects respondents by withholding from all persons not connected with the conduct of such research, the names or other identifying characteristics of respondents without their consent (attachment 5).

  1. Institutional Review Board (IRB) and Justification for Sensitive Questions


IRB Approval


This study has been reviewed and approved by the Abt Associates’ IRB (Attachment 4).


Sensitive Questions


This study is an initiative aimed to understand barriers and facilitators to HIV prevention, care, and treatment among transgender women at greatest risk for HIV infection and transmission. As such, our information collection entails measurement of sensitive HIV-related information. All contracting staff will be trained to provide respondents with city-specific hotlines for HIV and mental health care organizations as needed. No sensitive information will be collected during the semi-structured interviews with healthcare providers about the people they work with or any specific patients. We will inform all participants that they may skip any question or stop participation at any time for any reason.

  1. Estimates of Annualized Burden Hours and Costs


Exhibits A12.1 and A12.2 provide details about how the estimates of burden hours and costs were calculated. We calculated the overall burden per respondent by multiplying the frequency of response by the time to complete each data collection item. We anticipate that screener forms will take 5 minutes to complete. We anticipate 50 percent of transgender women screened will be eligible for the study. Healthcare providers will be referred to the study directly from the transgender women study participants, so they will not be screened. The in-depth interviews for transgender women and healthcare providers are expected to take a total of 60 minutes (1 hour) each. We will complete interviews for 40 transgender women and 10 healthcare providers in Atlanta, GA, Philadelphia, PA, and Washington, DC. We anticipate screening 80 potential transgender women respondents. The total number of burden hours is 61.

The annualized costs to the respondents are described in Exhibit 12.3. The United States Bureau of Labor Statistics’ employment and wages estimates from May, 2015 (http://www.bls.gov/oes/current/oes_nat.htm) were used to estimate the hourly wage rate for the general public for the purpose of this GenIC request. The total estimated cost of the burden to respondents is approximately $1,417.03. This cost represents the total burden hours of general respondents multiplied by the average hourly wage rate ($23.23).
