Abstract: Objective · To compile the osteoporosis prevention and control behavior scale for health care workers in community and evaluate its validity and reliability. Methods · In 20 standardized diagnosis and treatment pilot community health service centers for osteoporosis in Shanghai,400 healthcare workers were conveniently sampled to conduct the survey and 20 of them who were randomly sampled underwent retest 2 weeks later. The validity of the scale was evaluatedcontent validity and structural validity. The reliability of the scale was testedCronbachs α coefficient, retest reliability and split-half reliability. Results · A total of 19 items were retained after project analysis. Scale-level content validity index/universal agreement (S-CVI/UA) and scale-level CVI/average (S-CVI/Ave) were 0.944 and 0.992, respectively, after an entry with item-level CVI (I-CVI) less than 0.78 was deleted. Four common factors were extractedexploratory factor analysis, and the cumulative variance contribution rate was 85.94%. Results of confirmatory factor analysis indicated that the model was consistent with the theoretical assumption, and the fitness indexes χ2/df, CFI, GFI, and RMSEA were 3.323, 0.971,0.902, and 0.076, respectively. The overall Cronbachs α coefficient of this scale was 0.978 and the Cronbachs α coefficients of the four dimensions were all over 0.9. The intraclass correlation coefficient (ICC) of each item was greater than 0.7, and the ICC of the total scale was 0.654. The split-half reliability coefficient was 0.932. Conclusion · The osteoporosis prevention and control behavior scale has good reliability and validity and can be used to evaluate the implementation of osteoporosis prevention and control behavior of health care workers in community.
