This is particularly true for complex post\u2010traumatic stress disorder (CPTSD). Differentiating between the treatment impacts of PTSD and CPTSD (which includes both PTSD symptoms and disturbances in self\u2010organization [DSO]) may help ED providers address this common comorbidity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>The current study included 95 women (<jats:italic>M<\/jats:italic>\n<jats:sub>\n<jats:italic>age<\/jats:italic>\n<\/jats:sub>\u2009<jats:italic>=<\/jats:italic>\u200926\u2009years) with EDs (largely anorexia nervosa) who received residential treatment (<jats:italic>M<\/jats:italic>\u2009=\u200981\u2009days). Participants completed measures of ED symptoms, anxiety, depression, body mass index (BMI), ED\u2010specific health\u2010related quality\u2010of\u2010life (ED\u2010HRQoL) impairment, functional disability, and trauma symptoms at admission, week 4 of treatment, discharge, and 6 months post\u2010discharge.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All outcomes except BMI were more severe at admission and week 4 of treatment for individuals with comorbid trauma (based on probable CPTSD or exceeding the clinical threshold for PTSD and DSO symptom domains); however, these differences resolved by discharge and remained non\u2010significant at follow\u2010up. Some forms of comorbid trauma moderated outcome trajectories for anxiety, depression, and disability (but not ED symptoms), such that individuals with comorbid trauma showed slower improvement early in treatment, steeper improvement later in treatment, and greater resurgence after discharge.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>These findings highlight that PTSD and CPTSD symptom domains may be associated with more severe ED outcomes early in residential treatment that resolve by discharge, and may predict differential treatment response for secondary outcomes.
