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.
On February 27th, 2010 the sixth strongest earthquake in recorded history struck Chile. With over 500 deaths, the destruction of hundreds of buildings including schools, and a blackout that affected most of the country’s population, approximately 75% of Chile’s population was affected. Few studies with both pre- and post-disaster data exist and there is limited understanding of how children’s psychosocial functioning changes following exposure to a disaster.
Globally, posttraumatic stress disorder (PTSD) is a significant mental health issue among military service members and veterans. Within the US, around 13% of veterans have a PTSD diagnosis, with the prevalence of PTSD increasing significantly post-9/11 with conflicts in Iraq and Afghanistan, resulting in about 11-20 out of every 100 Veterans having PTSD.
