Psychometric Evaluation and Clinical Norms of a Dutch Version of the Body Uneasiness Test Among Individuals With...

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.

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.

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.

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.
