The purpose of this study was to develop a useful ADL (activities of daily living) index for healthy older people at home. First, a total of 130 items for 57 ADLs were selected from the four domains, considering to previous studies and theoretical validity. The survey was carried out on 2,100 older people, and the achievement rate for each item was calculated. As a result, the 15 ADL items constructed with a three level scale were selected.
Second, the survey consisting of 15 ADL items and a physical fitness test of the Ministry of Education, Science and Culture were carried out on 458 older people to examine useful ADL items and their scales. As a result of analyses from the viewpoints of aging, physical fitness level, and interrelationship among ADL items, the following useful 12 ADL items were proposed; in the locomotion domain, jumping across a ditch, walking, running up and down stairs, and transfer; in the manipulation domain, taking bedding in and out, buttoning a shirt; in stabi
lity domain, standing in the bus or train, dressing while standing (trousers), standing on one foot with eyes open; in the posture-change domain, sitting up, standing up from the floor.
Third, a questionnaire consisting of 12 ADL items and a physical fitness test of the Ministry of Education were administered to 5,715 subjects 65 years or older, to examine reliability and validity of the ADL index, the relationships between ADL score and various factors (ex. self-assessment of health status and physical fitness level, and exercise frequency/week), and to examine the screening basis to execute the physical fitness test based on distribution of ADL score. Test-retest reliability of the ADL index showed significant high correlations in 12 ADL items (0.674 ≦ r ≦ 0.886) and overall score (r=0.943). The ADL score was significantly related to age and physical fitness test scores, and tended to be higher in subjects with a higher self-assessment of health status and physical fitness level, and with exercised more. These results were considered to prove the utility of the present ADL index. Further, based on the result of examining relationships between distribution of overall ADL score and physical fitness test scores, useful screening bases using overall score or item scores were proposed to judge whether or not the physical fitness tests could be executed.
