改良版埃德蒙顿症状评估系统在老年维持性血液透析病人中应用的信效度验证

Verification of the reliability and validity of the modified Edmonton symptom assessment system in elderly patients receiving maintenance hemodialysis

目的 检验改良版埃德蒙顿症状评估系统(Edmonton symptom assessment system, ESAS)在老年维持性血液透析病人中应用的信效度。方法 采用便利抽样法对330例东南大学附属中大医院血液透析中心2023年11—12月行维持性血液透析治疗的老年病人(男184例,女146例)进行调查,检验改良版ESAS量表的信效度。结果 改良版ESAS量表共11个条目,各条目与总分的相关系数为0.60~0.77;探索性因子分析之后,共提取1个公因子,累计方差贡献率为48.25%,各个条目在相应的公因子上的因子负荷量为0.60~0.76;量表总Cronbach’s α系数为0.883,各条目Cronbach’s α系数为0.866~0.880,折半系数为0.856。结论 改良版ESAS量表具有较好的信效度,可用于老年维持性血液透析病人的症状评估。

Objective To evaluate the reliability and validity of the modified Edmonton symptom assessment system(ESAS)in the elderly patients undergoing maintenance hemodialysis(MHD).Methods A total of 330 elderly patients(184 males and 146 females)who received MHD treatment in Blood Purification Center of Zhongda Hospital Southeast University from November to December 2023 were investigated by convenience sampling method.And the reliability and validity of the modified ESAS scale was tested.Results There were 11 items in the modified ESAS scale,and the correlation coefficient between each item and the total score was 0.60-0.77.Exploratory factor analysis showed that one common factor was extracted,and the cumulative variance contribution rate was 48.25%.The factor load of each item on the corresponding common factor was 0.60-0.76.The total Cronbach’sαcoefficient of the scale was 0.883,the Cronbach’sαcoefficient of each item ranged 0.866-0.880,and the broken half coefficient was 0.856.Conclusions The modified ESAS scale has good reliability and validity,and can be used to evaluate the symptoms of the elderly MHD patients.
