“…There have also been studies that discussed aspects of reliability and validity in the FAQ as a part of other research foci. In looking at self-report versions in English and Spanish, some studies have found strong internal consistency (.81-.86; Contador et al, 2020; Tappen et al, 2010). One study looked at test–retest over the course of a year and found low-to-adequate correlations for NCs (.73), MCI (.81), and dementia (.63), and recommended that a change of 3.6 points on the FAQ be considered reliable change (Malek-Ahmadi et al, 2015).…”

Comprehensive Evaluation of the Functional Activities Questionnaire (FAQ) and Its Reliability and Validity

The Functional Activities Questionnaire (FAQ) is a collateral-report measure of difficulties in activities of daily living. Despite its widespread use, psychometric analyses have been limited in scope, piecemeal across samples, and limited primarily to classical test theory. This article consolidated and expanded psychometric analyses using tools from generalizability and item response theories among 27,916 individuals from the National Alzheimer’s Coordinating Center database who completed the FAQ. Reliability was evaluated with internal consistency, test–retest, and generalizability analyses. Validity was assessed via convergence with neurocognitive measures, classification accuracy with impairment stage, and confirmatory factor and item response theory analyses. Demographics did not impact scores and there was strong evidence for reliability (0.52-0.95), though coefficients were attenuated when restricted in range to diagnostic groups (e.g., normal cognition). There were strong correlations with neurocognitive measures ( rs: −.30 to −.59), strong classification accuracy (areas under the curve: .81-.99), and a single-factor model had excellent fit. All items evidenced strong item response theory discrimination and provided significant information regarding functional disability, albeit within a relatively restricted range. The FAQ is a reliable and valid measure of activities of daily living concerns for use in clinical/research settings. It best assesses mild levels of functional difficulty, which is helpful in distinguishing normal cognition from mild cognitive impairment and dementia.

“…Given BADL/IADL has been widely demonstrated to be associated with functional ability, identifying the specific profile of BADL/IADL was an important premise to understand and discriminate the functional heterogeneity among elder people [8]. Having said that, previous studies showed that discriminating functional limitation in older adults was still confusing and obscure, with roughly extensive categories or unreasonable merge of evaluating items [9][10][11][12]. Misclassification of functional limitation might be partially attributed to inappropriate definition of cut-points for BADL/IADL in some specific context.…”

Background Disability in aged people became one of the major challenges in China due to the acceleration of population aging. Nevertheless, there were limited methods to appropriately discriminate the degree of combined basic activity of daily living (BADL) and instrumental activity of daily living (IADL). The present study explored an empirical typology of the activity of daily living (ADL) and its association with health status among the elderly in China. Methods Data throughout the Chinese Longitudinal Healthy Longevity Survey (CLHLS) was retrieved and Latent profile analysis (LPA) was conducted to identify the subgroups of ADL for included elderly subjects. Multinomial regression was performed to detect the effect of identified characteristics with ADL subgroups, and the restricted cubic spine was drawn to show the changes in the relationship between age-specific ADL disability and BMI. Results The overall participants (n=8108) were divided into three ADL classes by LPA - ‘no BADL limitation-no IADL limitation’ (Class one, n=6062, 75%), ‘no BADL limitation- IADL impairment’ (Class two, n=1526, 19%), and ‘BADL impairment- IADL impairment’ (Class three, n=520, 6%). Compared with the participants in Class one, the oldest-old, living without spouse, lacking of exercise, short in social activities, having experience of falls, having comorbidity of diabetes, heart disease, stroke, decreased cognitive function, depression symptom were highly associated with Class two and Class three. Additionally, malnutrition and asthma were associated with combined BADL/IADL impairment (Class three), while illiteracy was only associated with IADL impairment (Class two). Furthermore, a statistically significant U-shape association was detected between age and BADL/IADL disability (Class three vs. Class two) as well as BMI and BADL/IADL disability (Class three vs. Class one). The elderly aged 80–90 with IADL impairment were less likely to evolve into combined BADL/IADL impairment, and the elderly who were underweight or obese may have higher risk of combined BADL/IADL impairment. Conclusion A novel functional assessment was explored based on LPA, by which elderly people could be classified into three distinct classes of combined BADL/IADL. The predictors identified with particular IADL/BADL classes could draw early attention to the onset of functional disability and enlighten targeted interventions to address consequent problems of aged people.

“…These cognitive processes include planning, interference control, dual-task coordination [17], shifting, updating, inhibition [18] and working memory [19], all of which play important roles in the performance of everyday functions from basic activities of daily living, such as grooming, through to more complex instrumental activities such as managing personal finances [20]. Each cognitive function serves a specific purpose but is used in combination with others to perform daily functions [21]. For example, effective dual-task coordination relies on both effective inhibitory function, which is the ability to suppress an irrelevant stimulus or inappropriate reaction, and working memory function, which is the temporary storing of information to be retrieved for learning and completing tasks [22].…”

Cognitive function of older adults engaging in physical activity

et al. 2020

Background: Physical activity can be classified as open-skilled or closed-skilled. Open-skilled physical activity, such as tennis, require participants to perform within a dynamic setting and respond to unpredictable and frequent environmental changes throughout the activity. Closed-skilled types of physical activity, such as swimming, are predictable and self-directed. However, the benefits of cognitive function in these two types of physical activities to older adults are unknown. This study examined the effects of participation in open-and closed-skilled physical activity on the cognitive function of older adults. Methods: The study recruited a total of 61 participants aged 65 years and over. Participant recruitment was achieved by distributing flyers asking for volunteers in various sports venues. Participants self-reported to be without medical conditions affecting their physical and cognitive function. All participants underwent a two-hour assessment session involving the completion of seven standardised cognitive function assessments, which were used to assess a range of cognitive function. Results: Overall mean scores across all of the assessments showed superior performance for the open-or closedskilled participants when compared with the no-physical-activity group. The results of 61 adults who participated in this study showed that closed-skilled physical activity was associated with better selective attention and visuospatial function while open-skilled physical activity was associated with better inhibition and cognitive flexibility function. No significant difference in self-regulation ability was found between the open-or closed-skilled groups. Conclusions: Open-skilled physical activity was associated with better inhibition, visual tracking, and cognitive flexibility while closed-skilled physical activity was associated with better selective attention and visuospatial perception. The findings have important practical implications for the health and quality of life of ageing populations, knowing which particular types of physical activity might affect the cognitive function.
