基于德尔菲法构建天津市职业病防治能力评估体系

Construction of Tianjin occupational disease prevention and control ability assessment system based on Delphi method

目的:建立一套系统科学、合理可行、具有良好信度的职业病防治能力评估体系,为天津市职业病防治工作提供参考依据。方法:于2022年8月,查阅文献提出评估体系的指标,以德尔菲法进行2轮职业卫生专家匿名咨询形成专家意见;根据界值法和专家意见对评估体系指标剔除、筛选、修改,最终确定体系指标。用Cronbach's alpha检验体系指标信度,形成天津市职业病防治能力评估体系。结果:本研究专家进行两轮咨询的问卷有效回收率分别为92.3%和100.0%;专家权威系数分别为0.84和0.82;对Kendall协调系数进行差异性检验,差异有统计学意义( P<0.05)。天津市职业病防治能力评估体系包括7个一级指标,17个二级指标和54个三级指标。一级指标、二级指标、三级指标和全部指标的Cronbach's alpha=0.91、0.98、0.98和0.98(>0.7)。 结论:初步构建了天津市职业病防治能力评估体系,为天津市职业病防治能力的调查提供了参考依据。

Objective To establish a systematic,scientific,reasonable,feasible and reliable evaluation system for occupational disease prevention and control capability,in order to provide reference for occupational disease prevention and control work in Tianjin City.Methods In August 2022,literature review was conducted to propose indicators for the evaluation system.Two rounds of anonymous consultation with occupational health experts were conducted using the Delphi method to form expert opinions.According to the boundary value method and expert opinions,eliminate,screen,and modify the evaluation system indicators to ultimately determine the system indicators.Use Cronbach's alpha to test the reliability of the system indicators and form a Tianjin occupational disease prevention and control capability evaluation system.Results It showed that the effective response rates of the two rounds of consultation conducted by experts in this study were 92.3%and 100.0%,respectively.The expert authority coefficients were 0.84 and 0.82,respectively.The Kendall coordination coefficient was tested for differences,and the differences were statistically significant(P<0.05).The Tianjin occupational disease prevention and control capability evaluation system includes 7 primary indicators,17 secondary indicators,and 54 tertiary indicators.The Cronbach's alpha of the primary,second,third level indicators and all indicators were 0.91,0.98,0.98,0.98(>0.7).Conclusion The preliminary evaluation system for occupational disease prevention and control capacity in Tianjin City has been established,providing a reference basis for the investigation of occupational disease prevention and control capacity in Tianjin City.
