摘要: 目的 建立农村儿童溺水危险水域的评级指标体系。方法 通过对水域的实地勘查建立危险水域的初级指标,采用Delphi法,根据各指标重要性得分均值筛选指标,并确定权重。结果 通过15个专家三轮的咨询,得到7个一级指标,25个二级指标。三轮问卷回收率分别为100%,93.3%,100%;专家权威系数为0.79;一级指标、二级指标重要性、必要性的协调系数均大于0.5,分别为0.862,0.705,0.823,0.696(均有P<0.01);各指标变异系数的范围为0.00~0.20,小于0.25。结论 本研究建立的农村儿童溺水危险水域评级指标体系结果稳定,具有可操作性。Abstract: Objective To construct a scientific and reasonable evaluation index system for water bodies for childhood drowning in rural area. Methods The dimensions of the indicator system was determined based on the survey of water bodies. A 3-round Delphi process was conducted. The weight of index was calculated by method of proportionate allocation. Results The index system including 7 first-class indicators and 25 second-class indicators was developed in according to three rounds of Delphi consultations by 15 specialists. The response rate of three rounds was 100%, 93.3% and 100%, respectively. The specialist authority coefficient was 0.79. The W for each class of indicator was 0.862, 0.705, 0.823 and 0.696, respectively(all P<0.01). The CV for each indicator ranged from 0.00 to 0.20. Conclusions The index system established in the study has good reliability and feasibility.
