全科医生认知功能评估量表在中国老年人中的试用

Primary Study of General Practitioner Assessment of Cognition on Chinese Elderly

目的:评价全科医生认知功能评估量表-The General Practitioner Assessment of Cognition(GPCOG)的中文译本的信度和效度。方法:对263名社区健康老人和住院及门诊老年患者进行GPCOG评定,两周后对随机抽取的31人进行重测,评估GPCOG的中文译本的信度及效度。结果:GPCOG患者评估部分的Cronbach’α系数是0.682,GPCOG患者部分各条目与总分的相关系数为0.499-0.940,各条目间的相关系数为0.408-0.610,各条目及总分的先后两次测定的相关系数为0.855-0.981。GPCOG灵敏度98.08%,特异度91.94%。GPCOG患者部分总分和知情者部分总分与ADL总分呈负相关(P<0.01)。GPCOG患者部分的ROC曲线下面积(AUC)为0.983。结论:GPCOG具有良好的信度和效度,值得在我国综合医院和社区医院及初级护理机构推广应用。

Objective： To evaluate the validity and reliability of the Chinese version of GPCOG.Methods： 263 subjects of community elderly and inpatient and outpatient elderly were rated with GPCOG.31 subjects were retested after two weeks,and the validity and reliability of GPCOG were examined.Results： The Cronbach’α coefficient of the patient portion of GPCOG was 0.682.The correlation coefficient of every item of the patient portion of GPCOG and total score was 0.499-0.940.The correlation coefficient of every item was 0.408-0.610.The test-tested coefficient was 0.855-0.981.The sensitivity of GPCOG was 98.08% and specificity was 91.94%.The total score of the patient portion and information portion were correlated to the score of ADL（P0.01）,and the area under the curve（AUC） was 0.983.Conclusion： With satisfactory reliability and validity,GPCOG can be applied to the general hospital,community hospital and primary care.
