The Psychogeriatric Assessment Scales (PAS) provide an assessment of the clinical changes seen in dementia and depression. Principal components analysis and latent trait analysis were used to develop a set of scales to summarize these clinical changes. 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). Results are reported on the reliability and validity of these scales using data from clinical samples in Sydney and Geneva and a population sample from Canberra. The scales were found to have excellent validity when judged against clinical diagnoses of dementia and depression and could distinguish Alzheimer's from vascular dementia. Cut-off points were developed to indicate correspondence between scale scores and clinical diagnoses. Percentile rank norms were developed from the Canberra population sample. The PAS is easy to administer and score and can be used by lay interviewers after training. It is intended for application both in research and in services for the elderly.
老年精神科评估量表（PAS）用于评估痴呆和抑郁症中出现的临床变化。采用主成分分析和潜在特质分析来制定一套量表，以总结这些临床变化。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 informant 的访谈（认知衰退、行为改变、中风）。使用悉尼和日内瓦临床样本以及堪培拉人群样本的数据，报告了这些量表的信度和效度。与痴呆和抑郁症的临床诊断相比，这些量表具有出色的效度，并且能够区分阿尔茨海默病和血管性痴呆。制定了截断点以表明量表分数与临床诊断之间的对应关系。百分位排名常模是根据堪培拉人群样本制定的。PAS易于实施和评分，经过培训的非专业访谈者即可使用。它适用于老年研究和服务领域。
