【摘要】 [目的]探讨肌肉骨骼疾患问卷(中文版)在造船行业的适用性。[方法]由北方某造船厂550名工人对肌肉骨骼疾患问卷(中文版)进行填写。通过计算折半信度和Cronbach’α系数来评价问卷的信度,通过分析结构效度和区分效度来评价问卷的效度。[结果]信度:肌肉骨骼疾患问卷(中文版)总的Cronbach’α系数为0.86,各维度的Cronbach’α系数范围为0.48~0.84;折半信度为0.73。效度:根据因子分析原则提取13个公因子,累计方差贡献率为64.10%,主要反映了7个方面,其中有2个是独立因子;区分效度中,静态负荷、动态负荷、重复性、工效学环境因素、工作频度及疲劳感、振动和电脑操作维度与问卷总条目的相关性分别为0.83、0.52、0.48、0.52、0.72、0.14和0.01,除振动和电脑操作外,其他因素均高于该维度与其他维度之间的相关性。各维度除动态负荷与重复性之间的相关系数为0.42,其他维度之间的相关系数均小于等于0.4。[结论]该问卷总体信效度尚可,适当调整后可以作为工作相关肌肉骨骼疾患的评价工具应用于我国造船作业人员中。更多还原

【Abstract】 [Objective] To assess the applicability of Chinese version Musculoskeletal Questionnaire(CMQ) in shipbuilding industry.[Methods] A total of 550 workers from a shipyard in North China filled in the CMQ. Split-half reliability and Cronbach’αcoefficient were used to assess the CMQ’s reliability. Construct validity and discriminant validity were used to assess the CMQ’s validity.[Results] The total Cronbach’α coefficient of CMQ was 0.86 and the coefficients of designed five dimensions were in the range of 0.48-0.84. The split-half reliability coefficient was 0.73. Thirteen common factors, including two independent factors, were identified, explained 64.10% of total variance, and reflected seven dimensions. The correlation coefficients of discriminant validity between each dimension(including static load, dynamic load, repetitive work, ergonomic environmental factor, frequency and fatigue, vibration, and computer operation) and total items were 0.83, 0.52, 0.48, 0.52, 0.72, 0.14, and 0.01, respectively. The correlation coefficients betweeneach dimension(except vibration and computer operation) and total items were higher than those between dimensions. The correlation coefficients between any two dimensions were less than or equal to 0.4 except that between dynamic load and repetitive work(0.42).[Conclusion] The reliability and validity of CMQ is fair to evaluate the work-related musculoskeletal disorders among shipbuilding workers in China after appropriate adjustment.更多还原
