“…These circumstances might have selected people with high motivation for health, physical function and cognitive function. In fact, our participants had JST‐IC scores higher than the standard value of 9.5, and maintained their IADL. We considered that there was no association between self‐reported health and decrease in FGO, as the relationship between reduced IADL and worse self‐reported health has been previously reported and there were more participants who maintained their IADL .…”

Aim To examine the association between a decrease in the frequency of going out and oral function in independent older adults living in the urban area of Tokyo. Methods The participants analyzed were 785 older adults from the “Takashimadaira Study” (344 men and 441 women, age 77.0 ± 4.6 years). This study investigated the following items: decrease in frequency of going out; basic characteristics (sex, age); physical factors, such as oral function (difficulty chewing, difficulty swallowing, dry mouth); body pain; the Japan Science and Technology Agency Index of Competence; physical activities; psychological factors, such as the Geriatric Depression Scale‐15 score; and social and environmental factors, such as the presence or absence of participation in organization activities. Results To investigate the factors associated with a decrease in frequency of going out, logistic regression analysis showed an association with age (OR 1.08, 95% CI 1.03–1.13), difficulty chewing (OR 2.41, 95% CI 1.52–3.83), dry mouth (OR 1.68, 95% CI 1.07–2.64), body pain (OR 1.78, 95% CI 1.14–2.78), Japan Science and Technology Agency Index of Competence scores (OR 0.91, 95% CI 0.84–0.99), physical activities (OR 0.99, 95% CI 0.98–1.00), Geriatric Depression Scale‐15 scores (OR 1.13, 95% CI 1.05–1.21) and organization activities (OR 1.94, 95% CI 1.22–3.07). Covariance structural analyses showed that both “difficulty chewing” and “dry mouth” significantly affected “decrease in frequency of going out.” In addition, decrease in frequency of going out was significantly affected by “ Geriatric Depression Scale‐15 scores” through oral function. Conclusions The relationship between oral function and decrease in frequency of going out was clarified, after the multifaceted factors were adjusted. Geriatr Gerontol Int 2019; 19: 792–797.

“…Social engagement was assessed using subitems in the Japan Science and Technology Agency Index of Competence [39,40]. Social engagement (i.e., participate in a neighborhood association, participate in regional events, engage in charity, assume a managerial position in a residents' association) is scored on a dichotomous rating scale (0 = "no", 1 = "yes"), and the item scores are summed to obtain a total score (range 0-4).…”

The aim of this cross-sectional study was to investigate relationships between individuals' ratings of satisfaction and performance of activities that they found meaningful and depressive symptoms. Data was obtained from 806 older adults (mean age 74.9 ± 6.3 years, women = 63.0%) who participated in a community-based health check survey (Tarumizu Study 2018). Participants selected meaningful activities from 95 activities using the Aid for Decision-Making in Occupation Choice and evaluated their satisfaction and performance. Depressive symptoms were assessed using the 15-item Geriatric Depression Scale (GDS-15) and defined by a GDS-15 score of ≥5. Non-linear logistic regression analyses were used separately by gender to examine the association between satisfaction and performance of meaningful activities and depressive symptoms. The prevalence of depressive symptoms was 15.8%. We found no significant difference between meaningful activity choice between older adults with depressive symptoms and those without, in both men and women. After adjusting for potential covariates, satisfaction was associated with depressive symptoms in both men (OR 0.52, 95% CI 0.35-0.77) and women (OR 0.67, 95% CI 0.49-0.91), but performance was limited in women (OR 0.87, 95% CI 0.77-0.99). Our findings suggest that depressive symptoms are associated with satisfaction in meaningful activities regardless of activity categories.

“…We used the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) and Japan Science and Technology Agency Index of Competence (JST-IC) as external standards [23,24]. Although both indexes measure higher-level competence in Lawton's seven-stage model of human behavior [25], the JST-IC assesses higher competences than the TMIG-IC [23]. Other information was also taken during the survey, including age, sex, education, medical history (cerebral apoplexy, heart disease, diabetic and depression), subjective economic status, household composition, and the ADQ.…”

“…Therefore, these indexes seemed reasonable as external standards. The TMIG-IC is related to certain health outcomes among older adults, including care needs, long-term care costs, and mortality [23,33,34]. Activity diversity may be associated with these health outcomes.…”

Recent research has suggested that the breadth and evenness of activity and activity diversity contribute to health outcomes among older adults. However, few established assessment tools for activity diversity have been developed. This study developed an Activity Diversity Questionnaire (ADQ) for older adults through expert consultation and a preliminary survey among 18 community-dwelling older adults. The diversity score was calculated according to Shannon’s entropy. In study 1, the intraclass correlation coefficients (ICC) of the diversity scores were determined for community-dwelling older adults (n = 30). In study 2, concurrent validity was tested with participants receiving comprehensive health checkups at the Itabashi ward in Japan in 2018 (n = 766). The correlation coefficients of the diversity scores were then calculated in reference to the Tokyo Metropolitan Institute of Gerontology Index of Competence and Japan Science and Technology Agency Index of Competence. The final version of the ADQ consisted of 20 total items with excellent test-retest reliability (ICC = 0.84) and moderate correlations with both the Tokyo Metropolitan Institute of Gerontology Index of Competence and Japan Science and Technology Agency Index of Competence (r = 0.48 and 0.60, respectively). The ADQ was developed through scientific procedures and revealed sufficient reliability and validity. As such, it is a scientifically validated tool for assessing activity diversity among older adults.
