ABSTRACT
OBJECTIVES: For the further development of the Korean Long-Term Care System, we analyzed the validity of the assessment tools of cognitive impairment and behavioral problems for the Korean Long-Term Care System. METHODS: We investigated 326 elderly people who were residing in Onyang 4-dong and Dogo-myun, Asan-si, Chungcheongnamdo. Our research team visited their residence and performed the assessment tools for the Korean Long-Term Care System and Korean version of the Mini-Mental State Examination (MMSE-K), Neuropsychiatric Inventory-Questionnaire (NPI-Q) and Seoul-Instrumental Activities of Daily Living (S-IADL). RESULTS: The correlation between the cognitive function tests and MMSE-K (r=0.579, p<0.001) and that between the behavioral problem tests and NPI-Q (r=0.688, p<0.001) were not as good as we expected. Moreover, if the items of the behavioral problem tests were decreased to 10 items as the government wanted, we got much lower correlation coefficiency. The cognitive function tests could not detect early cognitive deterioration in dementia. CONCLUSION: The assessment tools of cognitive impairment and behavioral problems for the Korean Long-Term Care System need modifications to promote validity.
