“…Numerous factors that affect functional decline have been identified using a new index (Koyano et al 1987(Koyano et al , 1991(Koyano et al , 1993, and we revealed significant associations between health behaviors and risk of decline in higher-level functional capacity (Tsubota-Utsugi et al 2011;Imai et al 2014). Personality traits are also considered to be an important factor in functional decline risk.…”

This measure is made up of three subscales: social role, intellectual activity, and instrumental activities of b Obtained by one-way analysis of variance for continuous variables and chi-squared test for categorical variables, comparing participants, died, moved, and unwilling to participate groups.…”

“…Impairment at any sublevel is more likely to impair the higher levels. Higher-level functional capacity encompasses the complex abilities in Lawton's last three stages (instrumental self-maintenance, intellectual activity, and social role performance), and the scale to assess these stages has been developed in Japan (Koyano et al 1987(Koyano et al , 1991(Koyano et al , 1993. This new index may identify risk factors and preventable causes of functional decline at an earlier stage compared to other existing scales.…”

Numerous factors that affect functional decline have been identified, and personality traits are considered to be an important factor in functional decline risk. The Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG) was developed to measure three higher-level functional capacities, instrumental activities of daily living, intellectual activity, and social roles, in Japanese elderly, which were previously not assessed adequately with existing scales of functional decline. The objective of this study was to explore the effect of personality traits as predictors of higher-level functional decline over a 7-year follow-up in a rural Japanese community. Data on 676 participants (mean 67.1 years) who were free of functional decline and had completed questionnaires at baseline and 7 years later, were analyzed. Demographic characteristics, lifestyle and personality characteristics were obtained from a self-administered questionnaire at baseline. Higher-level functional decline was examined using the subscales of the TMIG at baseline and at a 7-year follow-up examination. Over the 7-year study period, 21.7% of eligible participants reported decline in higher-level functional capacity. After adjustment for putative confounding factors, the traits that were significant predictors of decline in higher-level functional capacity at the 7-year follow-up had higher psychoticism scores [odds ratio (95% confidence interval) 2.12 (1.23-3.66)] and lower extraversion scores [1.89 (1.01-3.56)]. The personality traits of higher psychoticism and lower extraversion were significantly associated with a risk of future functional decline. A better understanding of these personality traits may help identify of at-risk individuals and could help reduce functional decline in older adults.

“…Seventeen ADL items were selected from the following seven ADL domains: (1) changing and holding posture, (2) dressing, (3) using the toilet, (4) walking, (5) bathing, (6) manual activity, and (7) movement and carrying. These domains and items were referenced to the following major ADL indices: basic ADL indices [8][9][10] , instrument ADL (IADL) indices [11][12][13] , unified indices of ADL-IADL 14,15) , and disability scales 16) . Each item was assessed by a dichotomous scale, "possible" or "impossible".…”

Age and gender differences in ADL ability were investigated using 568 Japanese partially dependent older people (PD, Mean age=82.2± ± ± ±7.76 years) living in welfare institutions. The subjects were asked about 17 ADL items representing 7 ADL domains by the professional staff working at subjects' institutions. Each item was assessed by a dichotomous scale of "possible" or "impossible". Item proportions of "possible" response were calculated for gender and age groups (60s, 70s, 80s and 90s). Two-way analysis of variance (ANOVA) using the arcsine transformation method indicated no gender differences. Significant decreases in ADL ability with aging were found in 13 of the 17 items. The dependency of ADL in the PD significantly increases with aging, and there is no significant difference in this trend between men and women. The dependency of more difficult activities using lower limb increase from the 70s, and independency of lowdifficult activities such as manual activities, feeding and changing posture while lying is maintained until the 80s and over.

“…Several indexes have been developed for evaluating the physical independence level of basic daily life activities [10], such as the Barthel Index [11] or physical self-maintenance scale, and for evaluating more advanced daily performance status [12], such as the instrumental ADL scale and the Tokyo Metropolitan Institute of Gerontology Index of Competence [13]. The Short-Form 36-Item Health Survey (SF-36) [14][15][16] is now frequently used in the evaluation of ADL and QOL, and this questionnaire comprehensively evaluates mental function as well as ADL from the perspective of physical and social functions.…”

Objectives There is a growing need to evaluate the performance status of the activities of daily living (ADL) of the elderly in the rapidly aging Japanese society. The purpose of this study was to verify the usefulness of our new scoring sheet for assessing present ADL status and to clarify whether or not the assessed ADL status can predict the future risk of adverse conditions related to falls. Methods The validation study was performed using 116 non-handicapped community-dwelling Japanese elderly at least 60 years of age. Of those subjects, 44 were also analyzed for the relationship between baseline ADL status and subsequent risk of adverse conditions related to falls. Results The daily living performance score sheet had good internal consistency, with a Cronbach's alpha of 0.82 and a sequential hierarchical structure that reflected the difficulty of the activities. The total score was significantly and positively associated with six of eight subscale scores on the Short-Form 36-Item Health Survey (P \ 0.01). In the follow-up study, every one-point decrease in total score was significantly associated with a 39% elevated risk of a stumble or fall (P = 0.022) and also borderline significantly associated with higher risks of a fall, anxiety while walking indoors, and anxiety while walking outdoors (P \ 0.10). Conclusion Our new scoring sheet can reliably and comprehensively assess present ADL status. The assessed ADL could predict the future risk of adverse conditions related to falls.
