焦虑自评量表在精神疾病患者中的因子结构研究

目的 探索焦虑自评量表(self-rating anxiety scale,SAS)在精神疾病患者样本中的因素结构及症状特点.方法 按焦虑程度分组比较SAS各项目的 特点;采用相关分析及探索性因素分析评价精神疾病患者SAS的因素结构及症状特点.结果 在无、轻、中、重度焦虑组间,SAS各条目得分上有明显差异,其中在躯体疼痛项目上两两组间差异均有显著性(P<0.05);SAS量表大部分条目间有明显的相关性(P<0.01或0.05),所有条目均与SDS量表总分有明显正相关性(r=0.24～0.64,P<0.01);经探索性因素分析SAS量表得到4因子结构,特征根分别为5.49,1.96,1.52,1.12,分别解释27.46%,9.82%,7.60%,5.58%的变异,共解释50.46%的总变异,其中因子1为躯体症状,解释了27.46%的变异.结论 以精神疾病患者为样本的SAS量表呈现出4因子结构,量表有较好的稳定性,SAS是反映与焦虑有关的躯体症状的重要测量工具.
