Abstract
Transgender and gender diverse (TGD) veterans in the Veterans Health Administration experience health and health care disparities, and research with this population is needed to improve gender-affirming care in Veterans Health Administration. However, TGD veterans may experience hesitancy to participate in research. We must address barriers to participation through feasible and acceptable methods. Opt-out letters are an effective tool used to recruit veterans in mental health research. The present study examined the feasibility and acceptability of opt-out letters modified for TGD veterans. Opt-out letters were sent to 54 potential TGD participants at three sites. The letters stated the research team would begin contacting veterans by phone in 2 weeks if they did not opt out of being contacted. Feasibility was measured through response rate. Acceptability was assessed through qualitative template analysis of interview data. Of the 54 potential participants, two opted out, three letters were undeliverable, and eight veterans called to opt in. Veterans reported that they found the letters to be clear and useful. The responses to the opt-out letters resulted in completing recruitment for two of the three sites. The research team then called the veterans who received the letter at the third site (three veterans) and recruited one additional veteran, for a total of nine TGD veterans. Opt-out letters may be a helpful tool to recruit TGD veterans to participate in research. Although these letters were designed to opt out, 89% of participants called the research team to opt in.
