Abstract
As Japan tries to balance the volume of long term care for the aged and its financing by promoting the preventive activities for slightly frail elderly, a simple case finding instrument is needed in order to implement really effective programs. For this purpose, the MHLW has introduced a 25 items questionnaire for case finding. However, this instrument is considered inappropriate because of its low sensitivity. In order to improve the situation, we have developed an 8 items’ simple questionnaire, so called Quick 8. According to the ROC analysis based on the data of 289 aged who received the secondary in-depth assessment, It seems the criteria “more than equal 4 (sensitivity=1.00 and specificity =0.714)” is appropriate as threshold. The effectiveness and validity of this new instrument must be examined by larger scale of field studies in future.
