摘 要: 目的研究快速上肢评估(RULA)在制鞋作业职业性肌肉骨骼疾患(WMSDs)评估中的信效度。方法采用RULA评估方法对某制鞋厂具有代表性工艺流程的375名工人作业活动进行评分,采用克朗巴哈α系数(Cronbach's α系数)、折半信度、重测者信度和评价者间信度进行信度检验;采用结构效度进行效度检验。结果Cronbach's α系数为0.807,折半信度Guttman Split-Half系数为0.640,RULA总得分的重测者信度和评价者间信度的组内相关系数(ICC)分别为0.708和0.645。因子分析中提取4个特征根>1的公因子,累积方差贡献率70.77%,4个公因子包含所有条目,与量表完全吻合,且公因子载荷均>0.4。结论RULA评估法在制鞋业中有较好的信效度,可在该行业应用。 |

Abstract: Objective To study the reliability and validity of rapid upper limb assessment(RULA)method applicated in shoe-making industry.Methods The RULA method was used to score the work activities of 375 workers from the representative technological process in a shoe-making factory;the Cronbach's a coefficient,half-reliability,retester reliability and interrator reliability were used for reliability test and the structural validity was used for validity test.Results The results showed that the Cronbach's a coefficient,Guttman Split-Half coefficient(for half-reliability)was 0.807 and 0.640,respectively,and the RULA total scores of intra-group correlation coefficients(ICC)retester reliability and interrater reliability was 0.708 and 0.645,respectively.4 common factors with characteristic root>1 were extracted from factor analysis,the cumulative variance contribution rate reached 70.77%,4 common factors contained all items,which were completely consistent with the scale,and the common factor loadings were all>0.4.Conclusion The results suggested that RULA method showed good reliability and validity,and can be applied in shoe-making industry. |
