Development of ADL index for older community people / 体力科学

ABSTRACT

The purposes of this study were to examine reliability and validity of ADL index for older people at home, and 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 for execution of physical fitness test based on distribution of ADL score. A questionnaire consisting of 12 ADL items and a physical fitness test of Ministry of Education, Science and Clture were administered to 5, 715 subjects 65 years or more age (male 2, 745; female 2, 970) . As a result of examining test-retest reliability of the ADL index, significant high correlations were shown among 12 ADL items (0.674≤r≤0.886), and in 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 more frequency. It was suggested that these results prove the utility of the present ADL index. Further, as the result of examining relationships between distribution of overall ADL score and physical fitness test scores, the following screening bases were considered to be valid for judgement whether the physical fitness tests could be executed. The three screening bases using overall ADL score were 1) 12 or under; 2) over 13 to under 24; 3) 24 and over. The four bases using item score were 1) a category 1 response for items 1, 5 and 6; 2) a category 2 or 3 response for items 1, 5 and 6, and a category 1 response for items 3 and 4; 3) a category 3 response for items 2 and 14; 4) a category 1 response for items 10 and 12.
