title: Reliability and validity of a Chinese version of the Modified Body Image Scale in patients with symptomatic pelvic organ prolapse.
abstract: OBJECTIVE
  To validate a Chinese version of the Modified Body Image Scale (MBIS) among patients with symptomatic pelvic organ prolapse.
  
  
  METHODS
  As part of a validation study at a center in Beijing, China, women with symptomatic pelvic organ prolapse stage II or greater completed the Chinese version of the MBIS, the 12-item Short-Form Health Survey (SF-12), and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). A sample of 30 women was randomly chosen to return 2weeks later to complete the questionnaires again. The reliability and validity of the MBIS were assessed.
  
  
  RESULTS
  Overall, 52 patients participated. A Cronbach α of 0.926 demonstrated adequate internal consistency of the Chinese MBIS. Its reproducibility was demonstrated by intraclass correlation coefficient values of 0.554-0.963 (P<0.01 for all items). Confirmatory factor analysis supported its construct validity. The MBIS and SF-12 scores were negatively correlated (r=-0.390; P<0.001), and the MBIS and PISQ-12 scores were also negatively correlated (r=-0.709; P<0.001).
  
  
  CONCLUSIONS
  The Chinese version of the MBIS is a reliable and valid tool to evaluate body image perception among patients with symptomatic pelvic organ prolapse.
