Objective
The Eating Pathology Symptoms Inventory [EPSI; Forbush KT, Wildes JE, Pollack LO, Dunbar D, Luo J, Patterson K, et al. Development and validation of the EPSI. Psychological Assessment, in press] is an empirically derived self‐report measure of eating disorder (ED) symptoms. The EPSI is able to capture the majority of variance associated with established ED measures, yet possesses additional content that is not currently represented in any existing multidimensional ED measure. The purpose of this study was to present normative and psychometric data for the EPSI in a large sample of college men (N = 502) and women (N = 625).
Method
Participants completed the EPSI and a battery of self‐report measures to evaluate convergent and discriminant validity. To provide context as to how normative scores compare to ED psychopathology, undergraduate student scores were compared to scores from individuals with EDs (N = 150).
Results
Confirmatory factor analyses indicated that the EPSI had a robust eight‐factor structure that was replicated in both men and women. Mean scores for most scales were significantly higher in women, except for Excessive Exercise, Muscle Building, and Negative Attitudes toward Obesity, which were significantly higher in men. Most scale scores were significantly lower in college students than in patients with EDs. Results indicated excellent convergent and discriminant validity in both genders.
Discussion
These data provide the first large‐scale normative data for the EPSI in young adults, as well as additional evidence supporting the psychometric properties and construct validity of the EPSI. © 2013 Wiley Periodicals, Inc. (Int J Eat Disord 2014; 47:85–91)
