摘　　要：目的:编制一个用于老年人痴呆筛查的问卷,检验问卷的信度和效度。方法:借鉴MMSE和ADL的评定范式编制一个以评估认知缺陷为核心,兼顾日常生活能力、精神症状和人格改变等内容的痴呆筛查问卷(简称DSI-E),包含11个领域55个条目;在2815名社区样本、215名重测样本和199名效度样本中,检验问卷的重测信度、同质信度和结构效度。结果:问卷总分的重测相关、分半相关和α系数分别为0.96,0.91和0.85;新编问卷与MMSE、ADL、MMAS记忆商数和CCAS智商的相关分别为0.92、0.89、0.71和0.63;因素分析获得3个因子,分别命名为认知能力、生活能力和精神病理,可解释60.1%的方差。结论:新编痴呆筛查问卷的信度和效度较理想,符合心理测量学要求。Objective： To develop a Dementia Screening Inventory for Elderly （DSI-E） and examine it＇s reliability and validity. Methods： In the light of rating model of MMSE and ADL, a screening inventory was developed to assess cognitive abilities, daily activities, and mental and personality changes for elderly, which contained 55 items across 11 areas. Two thousand eight hundred and fifteen community elderly were interviewed with the DSI-E; out of them, two hundred and fifteen were retested after two weeks, one hundred nlnety-nine were assessed with MMSE, ADL, MMAS, and CCAS. Results： The stability coefficient, split-half reliability, and Cronbach＇s α coefficient were 0.96, 0.91, and 0.85 respectively; The DSI-E was significantly correlated with MMSE （r=-0.92）, ADL （r=-0.89）, MMAS （r=-0.71）, and CCAS （r=0.63）. Factor analysis got three factors accounting for 60.1% of variance, which were named cognitive ability, daily activity, and psychopathology. Conclusion： The stability, internal consistency, and validity of the DSI-E are good and meet with psychometric standard.
