Reliability and Validity of the Korean Version of GMS-AGECAT / 신경정신의학

ABSTRACT

OBJECTIVES: This study aims to confirm the reliability and validity of the GMS-AGECAT(Geriatric Mental State-Automated Geriatric Examination for Computer Assisted Taxonomy in a Korean elderly population. METHODS: Translation committee developed Korean version GMS translating GMS-A3 after preliminary studies. Few changes from the original English version were necessary. A random sample(N= 1256 of the elderly(65+ years in Asan, community was assessed for diagnostic validity. A two-phase study was designed Korean version of GMS-AGECAT, MMSE and GDS rated by lay interviewer and clinical assessment by psychiatrists according to DSM-IV. A consecutive hospital sample(N=28 of the elderly(65+ years admitted in Hangang Sacred Heart Hospital was assessed for reliability, concurrent & procedural validity. RESULTS: Reliability coefficients of GMS-AGECAT diagnosis were Inter-rater kappa 0.78 and test-retest kappa 0.56. Correlation coefficients for concurrent validity were 0.76 with MMSE and 0.73 with GDS. Procedural validity of psychiatrist's GMS-AGECAT diagnosis and lay-interviewers' were as follow case/ no case distinction sensitivity 95.5%, specificity 75%; organicity distinction sensitivity 100%, specificity 83.3% and depression distinction, sensitivity 92.3%, specificity 100%. Diagnostic validity of DSM-IV diagnoses and GMS-AGECAT diagnoses were case/ no case distinction sensitivity 92.7%, specificity 81%, dementia distinction sensitivity 77.3%, specificity 92.1% and depression distinction sensitivity 83.6%, specificity 84.1%. CONCLUSIONS: This study confirms the reliability and validity of the GMS-AGECAT in Korean elderly. Korean version GMS can be used in the international comparison studies.
