ABSTRACT
Objective To develop the Chinese version of modified body image scale(MBIS) questionnaires, and to validate them in Chinese population. Methods The original English MBIS questionnaire was translated into Chinese, following the WHO cross-cultural adaptation of health-related quality of life measures. The reliability and validity of the Chinese version of MBIS questionnaires were evaluated in Chinese population, MRKH syndrome patients. Results Totally 50 patients with MRKH syndrome completed the MBIS and short-form 12-item health survey(SF-12)questionnaires.The Cronbach′s alpha of MBIS was 0.741,intraclass correlation coefficients were 0.472-0.815(P<0.01).MBIS scores were positively correlated with SF-12 scores(Spearman correlation coefficient was-0.409, P<0.01). Factor analysis showed that MBIS had one common factor. Conclusion Chinese version of MBIS has high reliability and validity in Chinese population,therefore is suitable for clinic and research.
ABSTRACT
Objective To study reliability and validity of incontinence impact questionnaire short form (IIQ-7) in the Chinese population. Methods IIQ-7 form was translated into Chinese; 74 patients with urinary incontinence completed the IIQ-7 simplified Chinese version and short-form 12-item health survey (SF-12) questionnaires. The urinary incontinence patient also ran a 1 hour pad test. Then, reliability and validity of those forms were analyzed. Results The Cronbach's alpha of IIQ-7 simplified Chinese version was 0. 824 (P <0. 01). The intra-class correlation coefficient of IIQ-7 simplified Chinese version was 0. 749 (P < 0.01) . IIQ-7 simplified Chinese version scores were negatively correlated with SF-12 scores (Spearman correlation coefficient: - 0. 570, P < 0. 01) , IIQ-7 simplified Chinese version scores were positively correlated with 1 hour pad test (Spearman correlation coefficient: 0.461, P < 0. 01) , IIQ-7 simplified Chinese version scores were also positively correlated with the course of disease (Spearman correlation coefficient: 0. 235 , P < 0. 05) . Factor analysis of IIQ-7 simplified Chinese version showed good construct validity. Conclusions The simplified Chinese version of IIQ-7 has higher reliability and validity in the Chinese population. They are highly recommended for clinical treatment and research.
