This study examined the tripartite model of depression and anxiety in 131 psychiatric outpatients, ages 55-87. Confirmatory factor analyses revealed that a 3-factor model provided an adequate fit to the observed data, that the 3-factor model was empirically superior to 1- or 2-factor models, and that the 3-factor structure obtained in the current sample of older adult outpatients converged with that obtained on a separate, younger 'sample. Negative affect was significantly related to depression and anxiety symptoms and syndromes, and positive affect was more highly related to depression than anxiety symptoms and syndromes. Ways for taking into account possible age-associated differences in emotion in older adults and thus improving the conceptual model of anxiety and depression are briefly noted.
本研究对131名年龄在55至87岁之间的精神科门诊患者的抑郁和焦虑三方模型进行了检验。验证性因素分析表明，三因素模型与观测数据拟合良好，该三因素模型在经验上优于单因素或双因素模型，并且在当前老年门诊患者样本中获得的三因素结构与在另一个较年轻样本中获得的结构一致。消极情绪与抑郁和焦虑症状及综合征显著相关，而积极情绪与抑郁症状及综合征的相关性高于焦虑症状及综合征。文中简要提及了考虑老年人情绪中可能存在的与年龄相关差异从而改进焦虑和抑郁概念模型的方法。
