The PAS is a standardized interview which assesses the changes seen in dementia and depression using a set of scales. There are three scales derived from an interview with the subject (cognitive impairment, depression, stroke) and three from an interview with an informant (cognitive decline, behaviour change, stroke). The aim was to provide data on the psychometric properties and validity of the PAS. The scales were originally developed using data from the first wave of a longitudinal study of the elderly. Reported here are further data on the PAS from the second wave of the same study, carried out 3 1/2 years later. The setting was a community survey carried out in the Australian city of Canberra. Seven hundred and nine elderly persons, with a mean age of 80 years, and 641 informants participated. Besides the PAS, participants were administered several other scales: the Mini-Mental State Examination, the Informant Questionnaire on Cognitive Decline in the Elderly, the National Adult Reading Test and the Goldberg anxiety and depression scales. Diagnoses of dementia and depression were made with the Canberra Interview for the Elderly, from which the PAS is derived. Confirmatory factor analysis replicated the five-factor model which underpins the PAS. The PAS was found to correlate with the other scales having similar content and showed correspondence with diagnoses of dementia and depression derived from the Canberra Interview for the Elderly. Longitudinal data supported the validity of the cognitive decline scale as a measure of change. Overall, the results support the original psychometric and validity research on the PAS.
老年精神状态评估量表（PAS）是一种标准化访谈，它使用一组量表来评估在痴呆和抑郁症中所观察到的变化。有三个量表源自对受试者的访谈（认知障碍、抑郁、中风），另外三个源自对知情者的访谈（认知衰退、行为改变、中风）。目的是提供有关PAS心理测量特性和效度的数据。这些量表最初是使用来自一项老年人纵向研究第一波的数据开发的。这里报告的是同一研究第二波（在3年半后进行）关于PAS的更多数据。研究背景是在澳大利亚堪培拉市进行的一项社区调查。709名平均年龄为80岁的老年人以及641名知情者参与了调查。除了PAS之外，还让参与者接受了其他几个量表的测试：简易精神状态检查表、老年人认知衰退知情者问卷、国家成人阅读测试以及戈德堡焦虑和抑郁量表。使用源自堪培拉老年人访谈（PAS即由此而来）对痴呆和抑郁症进行诊断。验证性因素分析重现了作为PAS基础的五因素模型。发现PAS与其他具有相似内容的量表相关，并且与源自堪培拉老年人访谈的痴呆和抑郁症诊断结果相符。纵向数据支持认知衰退量表作为变化衡量指标的效度。总体而言，这些结果支持了关于PAS最初的心理测量和效度研究。
