Background
The Eating Pathology Symptoms Inventory (EPSI) is a multidimensional self-report measure for the assessment of eating pathology and related aspects: Body Dissatisfaction, Binge Eating, Cognitive Restraint, Purging, Restricting, Excessive Exercise, Negative Attitudes Toward Obesity, and Muscle Building. The aims of the current studies were to provide a German translation of the EPSI and replicate the original EPSI’s psychometric properties and correlates.
Methods
In two cross-sectional surveys using convenience samples (n = 361 and n = 178), participants completed the German EPSI along with other questionnaires.
Results
In both studies, the EPSI’s eight-factor structure, high internal consistencies, and differential associations with other instruments assessing eating disorder-specific and general psychopathology as well as gender differences on the EPSI’s scales were largely replicated.
Conclusions
The German EPSI had sound psychometric properties that allow for a reliable and valid, multidimensional assessment of eating-disorder psychopathology.
Plain English summary
The Eating Pathology Symptoms Inventory (EPSI) is a questionnaire for measuring symptoms of eating disorders and related aspects. We translated the EPSI into German and demonstrate in two studies that its psychometric properties and correlates are comparable to the original English version and, thus, that it can be used by researchers and clinicians in German-speaking countries.
