【摘要】 [目的]探讨中文版职业重复性活动(OCRA)检查表应用于造船行业的信度和效度。[方法]应用OCRA检查表,评估北方某造船厂241名工人因重复性作业导致肌肉骨骼疾患的患病风险。通过分析重测信度、评分者信度和Cronbach’α系数来评价检查表的信度,通过分析区分效度来评价效度。[结果]该检查表的重测信度为0.60,各维度的重测信度值在0.35~0.86之间。评分者信度为0.44,各维度值在0.41~0.76之间。检查表Cronbach’α系数为0.63。恢复时间、频率、用力、姿势和其他因素维度与总表的相关系数分别为0.19、0.44、0.75、0.87、0.84。[结论]应用中文版OCRA检查表测量造船工人肌肉骨骼风险的信效度未达到理想要求,仍需要进一步调整。更多还原

【Abstract】 [Objective] To evaluate the reliability and validity of Chinese version Occupational Repetitive Actions(OCRA) Checklist used in shipbuilding industry. [Methods] The risk of work-related musculoskeletal disorders(WMSDs) in 241 workers at a shipyard in North China was evaluated by the OCRA Checklist. Intra-rater reliability, inter-rater reliability, and Cronbach’α coefficient were used to assess the reliability of the checklist; and discriminant validity was used to assess the validity. [Results] Regarding the OCRA Checklist applied, the intraclass correlation coefficients(ICC) of intra-rater reliability and interrater reliability were 0.60 and 0.44 respectively. Each factor’s intra-rater reliability and inter-rater reliability ranged from 0.35 to 0.86 and from 0.41 to 0.76 respectively. The Cronbach’α coefficient was 0.63. The correlation coefficients between each factor(including recovery, frequency, force, posture, and additional factor) and total items were 0.19, 0.44, 0.75, 0.87, and 0.84, respectively. [Conclusion] The Chinese version OCRA Checklist basically accommodates the requirements to assess shipbuilding workers’ WMSDs, but still needs further adjustment.更多还原
