知能筛查测验和三种文版的初测结果

The Cognitive Abilities Instrument (CASI)and Preliminary Findings with its Chinese Version CASI C一2.0.

“知能筛检测验”是一个用来评估基本认知功能有无缺损的工具，施测时间约１５一２０分钟，总分为１００分。它可对注意、心算、旧记忆、新记忆、时空定向、语言、构图、抽象概念、判断及思考流畅等能力作定量评估，并可换算到国际上常用的Ｍｉｎｉ一ＭｅｎｔａｌＳｔａｔｅＥｘａｍｉｎａｔｉｏｎ（ＭＭＳＥ），ＨａｓｅｇａｗａＤｅｍｅｎｔｉａＳｃｒｅｅｎｉｎｇＳｃａｌｅ（ＨＤＳＳ）等测验的大致分数。它可用来筛检失智症、追踪受试者认知能力的改变及区辨受试者在各认知领域方面能力的强弱。本测验现有中、英、日、西等语文的版本，各版本的题目内容皆顺应受试者之语言及生活背景而略有调整。在美国、日本、台湾等地测试的结果，显示本测验对失智症的筛检和追踪皆胜过ＭＭＳＥ及ＨＤＳＳ，也比较适用于未受过学校教育的老年人，且具有较好的信度和效度。

The Cognitive Abilities Screening Instrument(CASI)is a neuropsychological test thathas been designed to be readily adaptable for subjects of different cultural backgrounds.It has a totalscore of 100 and typically takes 15一20 minutes to administer.It can provide scores on the somecognitive domains.It can also generate estimated scores of the Mini一Mental State(3MS) Test,andthe Hasegawa Dementia Screening Scale(HDSS).Various scores from the CASl can be used to screenfor dementia ,to monitor within一individual changes in cognitive abilities, and to provide profiles ofcognitive impairments. A Chinese version of the CASI ,CASI C一2.0 , has been developed that isappropriate for the Chinese culture and suitable for individuals with little or no formal education.CASI C 2.0 was administered to 512 non一demented community residents and 65 dementia patientsin Taipei and Kinmen ,over 50% of whom had never attended school.Despite the differences in thesubjects’language and educational level ,findings with CASI C一2. 0 are comparable with thosefrom other versions of the CASI administered to English and Japanese一speaking subjects in the UnitedStates and Japan. CASI C一2.0 had a retest reliability of.92 and a retest gain of 3 points over a 3.5week interval. Among the normals ,performance on the CASI C一2.0 increased with education anddecrcased with aging.When four of its items werc used to screen for dementia , it had a sensitivity of.91 and a specificity of.90 ,and outperformed the MMSE and the HDSS.
