Utility of ADL Index for Partially Dependent Older People : Discriminating the Functional Level of an Older Population

金沢大学人間社会研究域人間科学系In the present study, the ADL index for the partially dependent older people (Demura et al., 1999) was applied to 218 bedridden (BED), 466 partilly dependent (PD) and 245 independent living (IL) people in older groups The purposes of this study were to clarify the meaning of the evaluation of this index and to examine how ADL items are useful in determining each older group. It is suggested that a perfect score with our ADL index means independent living level, and a score of zero means bedridden level. The results of discriminant analysis indicated that four items with low-difficulty, such as "eating, " "going to the toilet, " "tossing about in bed" and "writing, " are useful in determining if the PD is becoming bedridden. While five items with high-difficulty, such as "putting on slacks, " "putting on trousers, " "standing up from a sitting posture, " "going up stairs" and "washing the whole body, " are useful in determining if the PD is becoming independent living. Furthermore, it is inferred that the possibility of falling into a bedridden situation increases when the total score is 5 or less, while the functional level is close to independent living when the total score is 13 or more. These findings make clear the meaning of the evaluation of our ADL index. Furthermore, the functional level of older population may be screened using evaluation of total and item scores of this ADL index.
