Psychometric properties of the Body Image Scale in women with benign gynaecological conditions.

OBJECTIVES: To evaluate the psychometric properties of the Body Image Scale (originally designed for use in cancer) in women with benign gynaecological conditions. STUDY DESIGN: Prospective completion of the Body Image Scale by women participating in the EVALUATE Hysterectomy Trial. The scale was completed pre-operatively, then 6 weeks, 4 and 12 months post-operatively. The psychometric properties were evaluated by assessing the reliability, response prevalence, discriminant validity and sensitivity to change. Factor analysis was also conducted to determine the scale structure. RESULTS: The Body Image Scale showed good reliability and clinical validity. Differences between sub-groups of women were detected, demonstrating good discriminant validity. The Body Image Scale was shown to be responsive to changes in body image. CONCLUSIONS: The Body Image Scale was shown to be a reliable and valid tool for assessing body image in women with benign gynaecological conditions and for use in clinical trials involving such women.
