摘　　要：目的:为了对医务工作者接触感染性病原体造成职业暴露的风险进行全面评估,编制《医务工作者的感染性职业暴露风险调查表》,并评价调查表的信度和效度。方法:通过文献研究法和专家咨询法研制设计《医务工作者感染性职业暴露风险调查表》,对某三级甲等医疗机构的医务工作者进行调查,将调查结果通过条目分析和因子分析的方式筛选条目,并通过SPSS 20.0统计软件进行内部一致性、分半信度和结构效度的统计分析。结果:《医务工作者感染性职业暴露风险调查表》共有6个维度,包括50个条目;调查表的总Cronbach′sα系数为0.972,其中各维度的Cronbach′sα系数在0.736~0.973之间;分半信度系数分别为0.973和0.925,两者之间的相关系数是0.751;KMO的检验统计量是0.965,Bartlett球形检验的χ2值是22562.451,df是1176,P<0.001,并用主成分分析的方法对调查表进行Kaiser标准化的正交旋转,在13次迭代后收敛,共提取了6个主成分的因子,其贡献率为68.044%。结论:研究团队设计的《医务工作者感染性职业暴露风险调查表》具有良好的信度和效度,可作为医务工作者感染性职业暴露风险的评价工具。Objective:To prepare a"Risk Questionnaire of Infectious Occupational Exposure of Medical Workers"for comprehensive assessing the risk of occupational exposure to infectious pathogens among medical workers,and evaluate the reliability and validity of the questionnaire.Methods:The"Risk Questionnaire of Infectious Occupational Exposure of Medical Workers"was developed and designed using the literature research method and expert consultation method.The medical workers in a grad A tertiary medical institution were investigated,the items were screened by item and factor analysis,and the internal consistency,split-half reliability and structural validity were analyzed using SPSS 20.0 statistical software.Results:The"Risk Questionnaire of Infectious Occupational Exposure of Medical Workers"included 6 dimensions and 50 items.The total Cronbach′sαcoefficient of the questionnaire was 0.972,and the Cronbach′sαcoefficient of each dimension was between 0.736 and 0.973.The split-helf reliability coefficient of the questionnaire and each dimension were 0.973 and 0.925,respectively,and the correlation coefficient between two was 0.751.The KMO test statistic was 0.965,theχ2 value of Bartlett sphere test was 22562.451,and the df was 1176(P<0.001).The Kaiser normalized orthogonal rotation of questionnaire was implemented using principal component analysis,a total of 6 principal component factors were converged and extracted after 13 iterations,and the contribution rate of which was 68.044%.Conclusions:The"Risk Questionnaire of Infectious Occupational Exposure of Medical Workers"designed by the research team has good reliability and validity,which can be used as an assessment tool to evaluate the risk of infectious occupational exposure of medical workers.
