摘　　要：目的对老年失智失能量表进行可行性和信效度分析。方法采取方便抽样方法纳入成都市十三大区县共17个调查点的痴呆患者290例,使用基本资料调查表、简易精神状态评价量表(MMSE)、神经精神问卷(NPI)、躯体生活自理量表(PSMS)和老年失智失能量表进行评定。采用Cronbach’sα系数、Spearman-Brown系数、Guttman分半信度及重测信度等指标考察量表的信度,以MMSE、NPI、PSMS为效标,分别对老年失智失能量表的认知功能、精神行为症状和日常生活能力三个维度进行效标关联效度分析。结果共276例(95.17%)患者完成有效问卷填写。老年失智失能量表总评分及各维度评分的组内相关系数为0.828~0.976,Spearman-Brown系数为0.790~0.917,Guttman分半信度为0.812~0.857,Cronbach’sα系数为0.737~0.886。老年失智失能量表认知功能维度评分与效标MMSE评分呈正相关(r=0.948,P<0.01),精神行为症状维度评分与效标NPI评分呈正相关(r=0.893,P<0.01),日常生活能力维度评分与效标PSMS评分呈正相关(r=0.997,P<0.01)。量表各维度评分与总评分均呈正相关(r=0.634~0.841,P均<0.05)。结论老年失智失能量表具有良好的可行性,信效度较好,是评定老年失智失能状况的一种较为可靠的工具。Objective To analyze the feasibility,reliability and validity of the disability assessment for dementia scale for the elderly.Methods A total of 290 dementia patients from 17 survey sites in 13 districts and counties of Chengdu were enrolled by convenient sampling method,and they were assessed using demographic data inventory,Mini-Mental State Examination(MMSE),Neuropsychiatric Inventory(NPI),Physical Self-Maintenance Scale(PSMS)and disability assessment for dementia scale for the elderly.Cronbach’sαcoefficient,Spearman-Brown coefficient,Guttman split-half coefficient and test-retest reliability were used to evaluate the internal consistency of above scales.Criterion-related validity of the scale was analyzed based on MMSE,NPI and PSMS.Results A total of 276 patients(95.17%)completed valid questionnaires.The intraclass correlation coefficient of the total score and each dimension were between 0.828~0.976,the Spearman-Brown coefficient were between 0.790~0.917,the Guttman splithalf coefficient were between 0.812~0.857,and the Cronbach’sαcoefficient were between 0.737~0.886.The cognitive function dimension score was positively correlated with the MMSE score(r=0.948,P<0.01),the mental behavior symptom dimension score was positively correlated with the NPI score(r=0.893,P<0.01),and the daily living ability dimension score was positively correlated with the PSMS score(r=0.997,P<0.01).The dimensions scores were positively correlated with the total score of the scale(r=0.634~0.841,P<0.05).Conclusion Disability of dementia assessment scale has good feasibility,reliability and validity,which is a reliable tool to assess senile dementia and disability.
