Eating disorders and posttraumatic stress: phenomenological and treatment considerations using the two-factor model

Area of Science:

• Psychiatry and Clinical Psychology
• Trauma Studies
• Eating Disorder Research

Background:

• Eating disorders and posttraumatic stress disorder (PTSD) are significant public health concerns with profound individual impacts.
• Emerging evidence suggests a potential overlap or concomitance between these two distinct diagnostic categories.
• The isolated presentation of eating disorders may mask underlying trauma-related issues.

Purpose of the Study:

• To raise clinical awareness regarding the frequent co-occurrence of eating disorders and PTSD.
• To advocate for routine assessment of trauma history and symptoms in individuals presenting with eating disorders.
• To propose a therapeutic framework for managing comorbid eating disorders and PTSD.

Main Methods:

• Literature review and synthesis of existing data on the comorbidity of eating disorders and PTSD.
• Conceptual analysis based on the two-factor model of PTSD.
• Discussion of neuropersonologic therapy as a treatment modality.

Main Results:

• A significant association exists between eating disorders and posttraumatic stress disorder (PTSD).
• Trauma history and current trauma symptoms are relevant factors in the presentation of eating disorders.
• The two-factor model of PTSD offers a viable framework for understanding and treating comorbid conditions.

Conclusions:

• Clinicians should consider trauma assessment when evaluating patients with eating disorders.
• Integrated treatment approaches, informed by the two-factor model of PTSD, are recommended for comorbid cases.
• Neuropersonologic therapy is suggested as a suitable treatment strategy for concurrent eating disorder and PTSD diagnoses.
