| Research Abstract |
The Japanese society is aging rapidly. People of ages over 65 years shares 17 percent of the total population in 1999 and the share will increase. It is a serious problem how to keep or improve the quality of life (QOL) of elderly people. We aim to measure the QOL and develop composite indices to represent it.
For the purpose we investigate structures to represent the QOL of old demented patients by analyzing clinical data obtained in a ward. We deal with the objective QOL on the basis of clinical data which indicate the attitudes and ways of behavior in their daily life in the ward. We design three sets of measurement items which are considered closely related to one other. The first set consists of nine items about QOL, the second of nine items about the activities of daily living (ADL), and the third of a single item to assess the intellectual level on a dementia scale.
Multivariate analysis is performed for the data, and thus the spatial and the cluster structures of the nineteen items are obtained. The results are interpreted from a medical point of view, and new findings are presented on the correlated structure of the items. On the basis of those findings, we construct some indices to comprehend the QOL, which will serve for assessment, non-medical care and medical study. Furthermore, evaluation of therapeutic approaches are provided in a close connection with the QOL research. Lastly, we discuss the significance and the limitations of our findings, and examine the validity and the reliability of our study.
