“…In agreement with findings in population-based studies [ 29 – 30 ], our results indicated that low physical activity was a contributor to functional disability in older adults. A Mexican cross-sectional study showed that low physical activity was significantly associated with ADL and IADL limitations after adjustment for covariates [ 29 ].…”

“…A Mexican cross-sectional study showed that low physical activity was significantly associated with ADL and IADL limitations after adjustment for covariates [ 29 ]. Another research also found that physical inactivity was a factor strongly associated with ADL and IADL functional limitations in older Korean adults [ 30 ]. The contribution of physical activity to functional impairment may be mediated by a positive effect on muscle strength [ 31 ].…”

Background There are a variety of determinants that are key to functional disability of older adults. However, little is known regarding the relationship between cognitive frailty and disability among older people. The aims of this study were to examine the associations between cognitive frailty and its six components with instrumental activities of daily living (IADL) functioning in community-dwelling older adults. Methods A total of 313 community-dwelling older adults (aged ≥ 65 years) were recruited from eight community centers in central China. Cognitive frailty was operationalized using the Mini-Mental State Examination for the evaluation of cognitive status and the Fried criteria for the evaluation of physical frailty. The outcome was functional disability assessed by the IADL scale. The association between cognitive frailty, as well as its components, and IADL limitations was identified by conducting binary logistic regression analysis. Results The prevalence of cognitive frailty was 8.9% in this study. The results showed that cognitive frailty (OR = 22.86) and frailty without cognitive impairment (OR = 8.15) were associated with IADL limitations. Subdimensions of cognitive frailty, exhaustion, weakness, low physical activity and cognitive impairment components were independently associated with IADL limitations. Conclusion Cognitive frailty was associated with a higher prevalence of disability. Interventions for improving cognitive frailty should be developed to prevent IADL disability among community-dwelling older adults in China.

“…Specifically, out of the 19 studies that claimed EV based on predictions of functional outcomes, only eight included any type of covariates in their analyses (see Table 2, for details). Yet, it is well recognized that a variety of potential confounds (e.g., age, education, depressive symptoms) correlate both with performance on EF tests (for reviews, see Cortés Pascual et al, 2019; Snyder, 2013) and with daily functioning (Coventry et al, 2020; for review, see Mlinac & Feng, 2016; Nguyen et al, 2022). Thus, correlations between EF tests and IADL performance are meaningless from a practical standpoint, unless they hold after controlling for relevant confounds.…”

The term "ecological validity" (EV) has traditionally referred to test scores' ability to predict real-world functioning. However, a test's similarity to real-world tasks is sometimes mistaken for evidence of its ability to predict daily life, sometimes bypassing rigorous validation research. The goal of this systematic review was to examine the type and quality of evidence used to support claims of EV of novel face-valid tests of executive functions (EF). MEDLINE and PsychINFO databases were searched using the following terms: ecologic * AND neuropsychol * AND (executive function * OR executive dysfunction OR executive abilit * ). Thirty-two articles that explicitly stated that their results demonstrated EV of a novel face-valid test of EF were identified. Results showed that only 60% of studies based their claims about EV on test scores' ability to predict functional outcomes, with the remaining 40% relying on other evidence (e.g., correlations with other measures, participant feedback, group differences). Among the studies that did base their conclusions on test scores' ability to predict outcomes (n = 19), an overwhelming majority relied on behavioral rating scales, utilized small sample sizes and participant-to-variable ratios, and failed to control for covariates and multiple comparisons. Poor scientific rigor was particularly pronounced in studies of "naturalistic" tests. The present systematic review reveals significant conceptual, methodological, and statistical flaws among an overwhelming majority of studies that claim to have found support for the EV of a novel face-valid test of EF. We call upon authors, reviewers, and editors to safeguard the scientific rigor of research in this area. Public Significance StatementThis literature review reveals considerable inconsistency in the quality of evidence among neuropsychological studies that claim to have demonstrated "ecological validity" of tests designed to resemble real-world tasks and intended for use as predictors of patients' daily functioning. We call upon neuropsychologists to use clearer terminology and to avoid common pitfalls in this type of test development research to improve our field's ability to interpret results of neuropsychological evaluations.

“…In the 85 + age group, 7.37% of individuals had severe disabilities for ADLs and 12.06% for IADLs. A high rate of mortality was also observed among people who were undereducated, underweight, inactive, depressed, and suffering from three or more chronic diseases [ 9 ]. A study of 49,732 older adults in Japan showed that participation in cultural leisure activities may contribute to improved IADL scores.…”

Background Owing to an increase in life expectancy, it is common for the older adults to suffer from chronic diseases that can result in disability and a low quality of life. This study aimed to explore the influence of chronic diseases and multimorbidities on activities of daily living (ADLs) and instrumental ADLs (IADLs) in an older Chinese population. Methods Based on the Chinese Longitudinal Healthy Longevity Survey (2018), 9,155 older adults aged 65 years and above were included in the study. A self-administered questionnaire was used to collect information on demographic characteristics, chronic diseases, ADLs, and IADLs. The impact of factors affecting ADL and IADL impairment in older adults was analysed using binary logistic regression. Results In total, 66.3% participants had chronic diseases. Hypertension, heart disease, arthritis, diabetes and cerebrovascular disease were among the top chronic diseases. Of these, 33.7% participants had multimorbidities. The most common combination of the two chronic diseases was hypertension and heart disease (11.2%), whereas the most common combination of the three chronic diseases was hypertension, heart disease, and diabetes (3.18%). After categorising the older adults into four age groups, dementia, visual impairment, and hearing impairment were found to be more prevalent with increasing age. The prevalence of hypertension, heart disease, cerebrovascular disease, gastrointestinal ulcers, arthritis and chronic nephritis gradually increased with age until the age of 75 years, peaked in the 75–84 years age group, and then showed a decreasing trend with age. Multimorbidity prevalence followed a similar pattern. Regression analysis indicated that the increase in age group and the number of chronic diseases independently correlated with impairments in ADL as well as IADL. Additionally, gender, physical activity, educational background, obesity, depressive symptoms, and falls also had an impact on ADLs or IADLs. Conclusion Chronic diseases and multimorbidities are common in older adults, and it is important to note that aging, multimorbidity, obesity, and unhealthy lifestyle choices may interfere with ADLs or IADLs in older adults. Therefore, it is imperative that primary healthcare providers pay special attention to older adults and improve screening for multimorbidity and follow-up needs.
