Trauma and posttraumatic stress disorder (PTSD) are associated with eating disorders (EDs), which occur across all sexual orientations and gender identities. Prior traumas and PTSD also are reported to occur significantly more frequently in individuals identifying as lesbian, gay, bisexual, transgender, queer or questioning, non-binary, or other (LGBTQ+), but little is known about rates of PTSD in LGBTQ+ individuals with EDs admitted to residential treatment (RT).
