摘要: 目的 应用焦虑自评量表(SAS)和抑郁自评量表(SDS)调查肝硬化患者心理障碍状况,评价其在肝硬化患者中应用的信效度。方法 应用SAS和SDS量表对138例肝硬化患者进行问卷调查, 采用Cronbach’s α系数、分半系数、组内相关系数(ICC)反映量表的同质信度。采用探索性因子分析量表的结构效度,计算Kaiser-Meyer-Olkin(KMO)值,并作巴特利特球形检验(BTS)判断因子分析是否合适,采用主成分分析法提取因子。结果 本组肝硬化患者焦虑和抑郁患病率分别为38.2%和63.1%;SAS量表的Cronbach’s α系数为0.777,SDS量表的Cronbach’s α系数为0.782,两个量表具有良好的同质性信度;分别对SAS量表提取4个主要因子,其方差解释比例分别为15.4%、14.9%、10.6%和10.2%,4个因子累计解释总方差的51.1%;对于SDS量表提取5个主要因子,其方差解释比例分别为14.0%、12.6%、11.9%、10.3%和8.4%,5个因子累计解释总方差的57.4%;SAS和SDS量表重测分析发现,两次测量结果高度相关(P<0.001)。结论 应用SAS和SDS量表调查肝硬化患者焦虑和抑郁情况具有良好的信效度,可以用于肝硬化患者心理障碍的测定。

Abstract: Objective This study was designed to evaluate of reliability and validity of self-rating anxiety scale(SAS) and self-rating depression scale(SDS) in patients with liver cirrhosis. Methods A total of 138 patients with liver cirrhosis were enrolled in this study. The reliability and validity of the two scales was evaluated by Cronbach’s α co-efficient,intraclass correlation co-efficient (ICC),Kaiser-Meyer-Olkin (KMO) score and Bartlett’s test of sphericity(BTS). Results The prevalence of anxiety and depression in this series were 38.2% and 63.1%,respectively;SAS scale’ Cronbach's α coefficient was 0.777 and SDS scale’ was 0.782, indicating better homogeneity reliability; Twenty items of SAS and SDS scales were analyzed by exploratory factors to construct validity and four main factors were extracted from the SAS scale that showed the variances ratio were 15.4%,14.9%,10.6% and 10.2%,respectively,and four factors accounted for 51.1% of the total variance of accumulated explanation;Five main factors were extracted from SDS scales that showed the variance ratio were 14.0%,12.6%,11.9%,10.3% and 8.4%,respectively,with 57.4% of the total variance;The re-measurement analysis of SAS and SDS scale’s items found that the two measurements were highly correlated with each other (P<0.001). Conclusion SAS and SDS scales have a better reliability and validity in the investigation of psychological and mental impairment in patients with liver cirrhosis.
