中国肌肉骨骼疾患问卷编制与验证——附调查问卷

Establishment and verification of the Chinese Musculoskeletal Questionnaire--The questionnaire is attached in the attachment

目的编制中国肌肉骨骼疾患问卷(CMQ),并检验其信度与效度。方法通过文献检索、工作相关肌肉骨骼疾患(WMSDs)职业人群访谈、职业卫生与职业工效学专家调查,形成CMQ初始问卷。采用方便抽样方法,分别抽取436、443名制造业工人作为预测样本和验证样本,采用条目分析、探索性因子分析和验证性因子分析等方法,确定最终的CMQ并检验其信效度。结果①通过条目分析,确定CMQ主要由48个条目组成。②探索性因子分析提取出9个公因子,累积解释了WMSDs的70.721%变异量。③验证性因素分析结果显示,CMQ的9因子模型的χ^2/自由度比值为3.380、比较拟合指数为0.781、非标准拟合指数为0.764、标准化均方根残差为0.068、近似误差均方根为0.073。④信度与效度检验结果显示,CMQ的上下肢姿势负荷、颈部姿势负荷、背部姿势负荷、工作要求、社会支持、工作自主性、工作环境、工作制度和工作设施等9个公因子的题目信度为0.205~0.841,组成信度为0.545~0.894,收敛效度为0.377~0.834,各公因子间的相关系数小于其收敛效度之平方根。结论CMQ具有较好的信度和效度,是一个可靠、有效的WMSDs评估工具。

Objective To compile the Chinese Musculoskeletal Questionnaire(CMQ)and test its reliability and validity.Methods The initial CMQ was formed through studying literatures,interviewing professional workers who have work-related musculoskeletal disorders(WMSDs)and investigation with occupational health and ergonomics experts.Then,436 and 443 manufacturing workers were selected as prediction and verification samples respectively by convensence sampling method.The reliability and validity of the CMQ were tested by item analysis,exploratory factor analysis and confirmatory factor analysis.Results i)The CMQ composed of 48 items with item analysis.ii)Nine common factors of CMQ were extracted using exploratory factor analysis,which explained 70.721%of WMSDs variance.iii)The results of confirmatory factor analysis showed that the ratio of chi-square to degree of freedom was 3.380,the comparative fit index was 0.781,the Tucker-Lewis index was 0.764,the root mean square error of approximation was 0.073,and the standardized root mean square residual was 0.068.iv)The results showed that the item reliabilities of the 9 common factors of CMQ such as upper and lower limbs posture load,neck posture load,back posture load,job demand,social support,job control,job environment,job system and job facilities were 0.205-0.841,the composite reliabilities were 0.545-0.894,and the convergence efficiencies were 0.377-0.834.The correlation coefficients between the common factors were less than its square root of the convergence validities.Conclusion The CMQ has good reliability and validity,and is a reliable and effective tool for evaluating WMSDs.
