The 45-item Eating Pathology Symptoms Inventory (EPSI; Forbush et al., 2013) is a self-report, multidimensional measure of cognitions/behaviors associated with eating disorder diagnoses. The EPSI includes body image-related constructs such as body dissatisfaction and muscle building, in addition to six other scales. The EPSI can be administered on paper for free and without formal permissions to adults and adolescents. Administering the EPSI online requires written permission from the copyright holder; see the chapter for additional permissions, copyright, and contact information. This chapter briefly details the development of the EPSI and evidence for its psychometric properties. The EPSI has an eight-factor structure based on confirmatory factor analyses, and has demonstrated favorable structural similarity (e.g., different types of invariance) across men and women, different weight statuses, and adolescents and adults. The EPSI has also demonstrated favorable internal consistency reliability, test-retest reliability, convergent validity with related measures, discriminant validity from measures of negative affect and internalizing symptoms, and criterion-related validity by discriminating between different eating disorders. A description of instructions and scale/scoring, more specific information about the body dissatisfaction and muscle building scales, and a link to the full EPSI are provided. Information about an abbreviated version and translations is also included.

This chapter describes the potential emergence of body image concerns in individuals with ARFID. It also introduces a self-test called the Eating Pathology Symptoms Inventory (EPSI) that readers can take to determine whether body-image concerns are problematic for them. Lastly, it introduces strategies such as behavior experiments and reducing comparison-making to help reduce body-image concerns.
