Research Methods: Increasing Visibility of Transgender and Gender Diverse Individuals in Trauma and PTSD Research
Posted on 06/02/2022 by Kelly Harper, PhD; Zig Hinds, BS; Eli Benevides, BS; & Nicholas A. Livingston, PhD
It is estimated that approximately 1.4 million people in the United States identify as transgender, including approximately 140,000 veterans and service members (Gates & Herman, 2014; Herman et al., 2017). However, transgender and gender diverse (TGD) individuals are often not reflected in research studies, either as a function of researchers not gathering expansive gender identity demographic information or not reporting this information in their published reports. For example, the PTSD Trials Standardized Data Repository includes information on randomized clinical trials (RCTs) for posttraumatic stress disorder (PTSD), including study information, outcomes, and sample characteristics. As of 2022, of 390 RCTs targeting PTSD, zero studies reported participants’ gender identities other than “male” or “female” and only one reported sexual orientation.
