Concurrent Treatment of Eating Disorders and PTSD Leads to Long-Term Recovery

Concurrent treatments targeting eating disorders and PTSD are needed to help these patients with complex conditions.

Research shows an undeniable connection between posttraumatic stress disorder (PTSD) and eating disorders (EDs). Individuals with significant traumatic histories and/or PTSD have more severe ED symptoms, more suicidality, and more anxiety and depressive symptoms.

Studying the intersection between these 2 mental health illnesses helps us understand how to treat them together moving forward, specifically in higher levels of care, including residential ED treatment programs.


Groundbreaking research published in the Journal of Eating Disorders shows the effectiveness of integrating trauma treatment with evidenced-based ED treatment in residential programs. The conventional thinking in psychiatry had been that it was best to refrain from trauma work while in intensive treatment settings, deferring this to later outpatient treatment. These research results demonstrate that multimodal, integrated treatment approaches based on principles of cognitive processing therapy (CPT) that address trauma and PTSD can be successfully delivered in residential treatment to patients with PTSD and associated comorbidity.


PTSD in Higher Levels of ED Treatment

Research from the past few years indicates that PTSD is common in patients receiving higher levels of care. In 2020, we reported that nearly half (49%) of adults admitted to residential ED treatment met the criteria for PTSD,2 whereas results from an additional study from 2021 found that of 613 adults in residential treatment, 53% were reported to likely have PTSD based on PCL-5 >33.3 Furthermore, 35% of women in ED residential treatment also had PTSD, according to results from a 2021 study (Figure 1).


Figure 1 for PTSD Research in Higher Levels of Care.

Individuals with EDs and comorbid PTSD experience more severe anxiety, depression, ED symptoms, and poorer quality of life compared with those without PTSD. Adults with EDs and PTSD had significantly higher scores than patients without PTSD on all measures, including total number of traumas on the Life Events Checklist (P < .001), global and all subscale scores on the Eating Disorder Examination Questionnaire (P < .001), depression scores on the Patient Health Questionnaire (P < .001), and scores on the Spielberger State-Trait Anxiety Inventory (state P < .001; trait P < .001).


Additionally, research shows that PTSD is common among adolescents who are admitted to ED residential programs. Adolescents with EDs and PTSD experienced more severe ED symptoms and poorer quality of life compared with those without PTSD in ED treatment. Our research reported that of the 647 adolescents with EDs admitted to residential treatment, 38% met criteria for PTSD and 75% endorsed at least 1 type of childhood trauma. Those who experienced ED onset from the age of 5 to 10 years had higher rates of PTSD (76%) compared with those who experienced ED onset from the age of 11 to 17 years (45%) and those who experienced ED onset as adults (31%; P < .001). Childhood onset of an ED is associated with more traumatic experiences and current PTSD diagnosis, increased severity of ED and comorbid psychopathology, higher body mass index, and more prior inpatient and residential admissions for ED treatment.


Sexual and gender minority individuals in ED treatment have significantly higher rates of PTSD compared with those who do not identify as LGBTQ+. Individuals with EDs and PTSD who identify as LGBTQ+ experience more severe ED symptoms and poorer quality of life. Of the 24% of participants in our study who identified as LGBTQ+, 63% met criteria for PTSD compared with 45% of cisgender heterosexual individuals.


Outcomes With Concurrent Treatment

Using an integrated clinical approach based on principles of CPT and other evidence-based treatments, we studied outcomes at discharge and 6 months following discharge in 609 patients (96% female; mean age [+/- SD], 26.0 years [+/- 8.8 years]; 22% LGBTQ+) with and without PTSD. All patients improved significantly and retained improvements at follow-up compared with admission. However, all measured symptoms, including those of EDs, major depression, state and trait anxiety, and quality of life, were higher in patients with PTSD at every time point (admission, discharge, and follow-up).


Going beyond trauma-informed care by providing evidence-based trauma treatment results in better outcomes. We integrated CPT, 1 of 3 gold-standard PTSD treatment options, into comprehensive ED treatment based on cognitive behavioral therapy and dialectical behavior therapy.


Results from the study showed that 81% of patients with PTSD at admission had significant reductions in trauma symptom scores from admission to discharge and 73% of patients with PTSD at admission had significant reductions in scores from admission to follow-up 6 months later. Not only did patients achieve sustained improvements in ED symptoms, but they also gained significant, long-term relief from trauma symptoms after completing programming using an integrated, multimodal clinical approach. Postdischarge outcomes data show that not only treating patients’ mental health illnesses but also providing them with tools and coping skills to self-manage symptoms and maintain recovery can help patients get well and stay well longer.

Concluding Thoughts


There is growing consensus in the ED field that integrated, concurrent treatments targeting EDs and PTSD are needed to help these patients with complex conditions.2,4,7-10 The findings of this study conclude that concurrent, parallel, and interwoven approaches to treatment, one for the ED and one for PTSD, can be delivered during the same treatment course by the same providers and therapists. Integrated therapy techniques for PTSD and related disorders can be delivered successfully in residential treatment and are associated with lasting improvements 6 months after discharge (Figure 2). The hope for this research and these findings is that they may help others in the ED field develop more effective and integrated treatment approaches for patients with PTSD admitted to higher levels of care for ED treatment.
