Psychometric Evaluation and Clinical Norms of a Dutch Version of the Body Uneasiness Test Among Individuals With Self‐Reported Eating Disorder Pathology

INTRODUCTION: The present study evaluates the psychometric properties and provides normative data for the Dutch Body Uneasiness Test. The instrument was administered to a clinical sample (N = 448) and a community-based sample (N = 223). The Body Uneasiness Test was translated and back-translated. METHODS: Internal consistency, item-rest correlation, test-retest reliability, and concurrent validity were assessed. The Body Shape Questionnaire and the Eating Disorder Examination-Shape concern subscale were used as reference measures. To establish criterion validity, a receiver-operating-characteristic curve-analysis was performed using both groups as reference groups. Confirmatory factor analysis tested five- and eight-factor structures. Norms (population-based T-scores and percentile scores) were established. RESULTS: The psychometric properties were good, with the Body Uneasiness Test distinguishing well between individuals with and without eating disorder pathology (area-under-the-curve value = 0.77-0.88). The Body Uneasiness Test-A had a five-factor structure, and the Body Uneasiness Test-B had an eight-factor structure. In accordance with other samples, clinical cut-off for the Body Uneasiness Test A was 1.2. CONCLUSIONS: These results suggested that the Dutch Body Uneasiness Test is a useful tool for screening various aspects of body image in individuals with eating disorder pathology in research and in clinical practice.
