Abstract
Purpose: This study examined the psychometric properties and provided normative data of the Dutch Body Shape Questionnaire (BSQ34) and its shortened BSQ8C among patients with binge-eating disorder.
Methods: The two versions of the BSQ were administered to patients with binge-eating disorder (N = 155) enrolled for treatment, and to a community sample (N = 333). The translation and back-translation of the BSQ were performed by translators with and without eating-disorder expertise. Internal consistency, concurrent validity, test-retest reliability, incremental validity, and sensitivity to change were determined. A receiver-operating-characteristic curve-analysis was used to establish criterion-related validity, for which the Eating Disorder Examination-Shape concern subscale, was used. Uni-dimensionality of the instrument was investigated with confirmatory factor analysis. Norms (population-based T-scores and clinical percentile-scores) were determined.
Results: The psychometric properties of the BSQs were satisfactory. The BSQ34 discriminated well in body-shape dissatisfaction between patients with binge-eating disorder and the community sample (area-under-the-curve value = 0.91-0.98) and had a unidimensional factor structure. Comparing structural invariance between both samples revealed that scaler invariance was not supported, indicating that items may be interpreted differently by patients with binge-eating disorder and subjects from the community. Analyses were repeated for the BSQ8C, which yielded similar results.
Conclusion: The results indicated that both versions of the BSQ appeared suitable to screen for body-shape dissatisfaction among patients with binge-eating disorder. The BSQ34 supplies valuable information on the various types of concerns respondents have, which are critical to consider in clinical settings; the BSQ8C is recommended as a short screening tool.
Level of evidence: Level III: Evidence obtained from well-designed cohort or case-control analytic studies.
期刊介绍：
Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity is a scientific journal whose main purpose is to create an international forum devoted to the several sectors of eating disorders and obesity and the significant relations between them. The journal publishes basic research, clinical and theoretical articles on eating disorders and weight-related problems: anorexia nervosa, bulimia nervosa, subthreshold eating disorders, obesity, atypical patterns of eating behaviour and body weight regulation in clinical and non-clinical populations.
