目的构建适合湖北武汉城市圈重大疾病流行特点的预警指标体系,并通过实证研究对其进行评价。方法采用Delphi法构建指标体系,甄选16名省内外专家和武汉城市圈9大城市的18名管理和工作人员参与研究,结合层次分析法确定指标权重,通过实证研究对指标体系的信度、效度和权重设置的合理性进行评价。结果 “武汉城市圈重大疾病预警指标体系”由3项一级指标,10项二级指标和41项三级指标组成,专家权威系数和熟悉程度均>0.90,总指标体系和一级指标的克朗巴哈α系数及半分信度系数分均>0.80,三级指标与所属一级指标相关系数均数>0.51,大于它与其他一级指标的相关系数,差异有统计学意义(P<0.05),指标重要性评分与综合评分一致性检验显示Kendall Wa=0.730(P<0.05)。结论预警指标体系具有良好的信度和效度,权重系数设置合理。
Objective To construct an early warning index system suitable for the epidemiological characteristics of major diseases in the Wuhan urban agglomeration of Hubei Province and to evaluate it through empirical research. Methods Delphi method was used to construct the index system. Sixteen managers and staff members from 16 domestic and overseas experts and 9 major cities in Wuhan metropolitan area were selected to participate in the research. The analytic hierarchy process was used to determine the weight of indicators. The empirical research was conducted to evaluate the reliability and effectiveness of the index system Degree and weight set the rationality of evaluation. Results “Wuhan City Circle Major Disease Warning Index System ” consists of three first-level indicators, ten second-level indicators and 41 third-level indicators, the expert’s authoritative coefficient and familiarity are> 0.90, the total indicator system and the first-level indicators (P <0.05). The correlation coefficient between the third grade index and the first grade index is> 0.51, which is larger than the correlation coefficient between it and other first grade indexes (P < 0.05). The consistency test of the importance score and the comprehensive score showed Kendall Wa = 0.730 (P <0.05). Conclusion The early warning index system has good reliability and validity, and the weight coefficient is set reasonably.
