Objective To evaluate the reliability and validity of musculoskeletal questionnaire.Methods A self-administered modified musculoskeletal questionnaire was used to investigate 12 098 workers from eight occupations,i.e,coal mining,petroleum,metallurgical,mechanical manufacturing,chemical,garment and railroad transportation industries and education.The Cronbach's α coefficient,analysis of covariance and multiple logistic regression were used to assess the reliability and validity of musculoskeletal questionnaire.Results The consistent test between total items of Musculoskeletal Questionnaire and each factor showed that the range of Cronbach's α was 0.52-0.92,except from vibration factor,other Cronbach' sα was more than 0.7.All 55 items of Musculoskeletal Questionnaire were subjected to factor analysis,and ten latent factom were identified,which explained 55.17％ of the total variance.The potentially hazardous working conditions could be categorized into seven dimensions (force,dynamic load,static load,repetitive load,climate factors,vibration exposure and environmental ergonomic factor),which consisted with the theory model.The results of covariance analysis indicated that there were significant difference among 7 dimension indices in different jobs (P＜0.01).Conclusion The modified Musculoskeletal Questionnaire is a valid and reliable tool for measuring musculoskeletal workload.
