Objective:
To develop a questionnaire for assessing bone health literacy among perimenopausal and postmenopausal women in Shanghai, and to evaluate reliability and validity of the questionnaire and to provide scientific evidence for generalizing the application of the questionnaire in the elderly METHODS The questionnaire was developed based on the integrated theoretical model of health literacy proposed by Regional Office for Europe of World Health Organization in 2012. Using relevant questionnaires in domestic and abroad literatures for reference, through two rounds of expert consultation, 45 items of bone health literacy questionnaire were formed. After evaluating the repeatability and effectiveness of the questionnaire, a questionnaire on bone health literacy for middle-aged and elderly women was formed. 40 items of bone health literacy questionnaire for perimenopausal and elderly women were summarized. Cronbachs a and split-half reliability were calculated to evaluate the reliability of bone health literacy questionnaire, and content, discriminant, convergent and structural validity were performed to measure the validity of the questionnaire RESULTS A total of 447 community women aged 45-65 were investigated. The overall Cronbachs a of bone health literacy questionnaire was 0.763 and the split-half reliability was 0.793. The correlation coefficient of each sub-questionnaire with the total questionnaire was 0.403~0.703. The bone health literacy questionnaire had good content validity, with the success rate of calibration experiment of 57.50% and 86.25% respectively, Confirmatory factor analysis showed that the goodness of fit index (GFI) and other indicators reached the adaptation standard, and the structural validity was good.

Conclusion:
The questionnaire has good reliability and validity, and can be used as a simple tool to measure and evaluate bone health literacy.
