目的：为探讨结构性失用症的一种常用测量方法--徒手画钟表的可靠性和有效性，在阿尔茨海默病患者中进行研究。设计：为检验一种新量表的可靠性和有效性而进行的调查。设置：位于上中西部的一所大学附属医院的记忆障碍门诊。患者：46名患者在痴呆评估后被诊断为临床上可能的阿尔茨海默型痴呆，和26名正常老年人对照组是研究志愿者，没有认知功能障碍的历史。测量：神经心理学测试，痴呆相关的规模，和时钟图纸评定的一个新的20项时钟图纸解释量表。可靠性措施，相关性，并在CDIS.Results项目聚类：CDIS评分员间的可靠性（r = 0.94），内部一致性（r（tt）= 0.95），并在6个月的时间间隔的再现性。CDIS评分与两个痴呆相关量表和所有神经心理学测试显著相关，与其他结构性失用症指标的相关性最高。所有，但四个阿尔茨海默氏症患者（91%），没有一个控制CDIS评分为18或更低。结论：临床医生可以可靠地筛选阿尔茨海默氏症患者的时钟绘图任务，一个措施的缺陷敏感的结构性失用症。
Objective: To investigate the reliability and validity of free-hand clock drawings, a frequently used measure of constructional apraxia, in patients with Alzheimer's disease.Design: Survey for the purpose of testing reliability and validity of a new scale.Setting: Memory Disorder Clinic at a university-affiliated hospital in the Upper Midwest.Patients: Forty-six patients were diagnosed with clinically probable dementia of the Alzheimer type after a dementia evaluation, and 26 normal elderly controls were research volunteers without a history of cognitive dysfunction.Measurements: Neuropsychological tests, dementia-related scales, and clock drawings rated by a new 20-item Clock Drawing Interpretation Scale. Reliability measures, correlations, and clustering of items in the CDIS.Results: The CDIS had inter-rater reliability (r = .94), internal consistence (r(tt) = .95), and reproducibility over a 6-month interval. CDIS scores were significantly correlated with two dementia-related scales and all neuropsychological tests and had the highest correlations with other measures of constructional apraxia. All but four Alzheimer patients (91%) and none of the controls had CDIS scores of 18 or less.Conclusion: Clinicians may reliably screen patients with Alzheimer s disease with the clock-drawing task, a measure sensitive to deficits in constructional apraxia.
