Primary Study of General Practitioner Assessment of Cognition on Chinese Elderly

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.
