A Study on Translation Process into Korean Version of the Life-Space Assessment to Assess Community Mobility for Elderly

The purpose of this study was to evaluate the reliability and validity of a Korean version of the 20-item COVID-19 phobia tool, which was developed through a translation-reverse translation process. These data were collected from 226 persons using a self-reported questionnaire. Exploratory and confirmatory factor analyses were used to test construct validity. Finally, for 19 out of 20 items, the item-level convergence and differential validity were confirmed. In addition, the reliability and validity of the tool as a whole has been verified. For the subscales, Cronbach’s α was 0.90 for psychological, 0.87 for psychosomatic, 0.86 for economic, and 0.87 for social. Appropriate reliability was confirmed. Correlations between the COVID-19 phobia tool and fear of COVID-19 confirmed validity. The Korean version of the COVID-19 phobia tool is an appropriate scale for measuring the fear of COVID-19 and relevant psychological characteristics. Therefore, future studies in areas such as health and nursing could use this tool as required.

Abstract Background Real-life community mobility (CM) measures for older adults, especially those with Parkinson’s disease (PD), are important tools when helping individuals maintain optimal function and quality of life. This is one of the first studies to compare an objective global positioning system (GPS) sensor and subjective self-report CM measures in an older clinical population. Methods Over 14 days, 54 people in Ontario, Canada with early to mid-stage PD (mean age = 67.5 ± 6.3 years; 47 men; 46 retired) wore a wireless inertial measurement unit with GPS (WIMU-GPS), and completed the Life Space Assessment and mobility diaries. We assessed the convergent validity, reliability and agreement on mobility outcomes using Spearman’s correlation, intraclass correlation coefficient, and Bland-Altman analyses, respectively. Results Convergent validity was attained by the WIMU-GPS for trip frequency (rs = .69, 95% confidence interval [CI] = 0.52–0.81) and duration outside (rs = .43, 95% CI = 0.18–0.62), but not for life space size (rs = .39, 95% CI = 0.14–0.60). The Life Space Assessment exhibited floor and ceiling effects. Moderate agreements were observed between WIMU-GPS and diary for trip frequency and duration (intraclass correlation coefficients = 0.71, 95% CI = 0.51–0.82; 0.67, 95% CI = 0.42–0.82, respectively). Disagreement was more common among nonretired individuals. Conclusions WIMU-GPS could replace diaries for trip frequency and duration assessments in older adults with PD. Both assessments are best used for retired persons. However, the Life Space Assessment may not reflect actual mobility.

Abstract The University of Alabama at Birmingham Life-Space Assessment (LSA) is a self-reported measure for assessing community mobility. Restricted mobility is correlated with a number of adverse health outcomes, including mortality, frailty, cognitive decline, and nursing home admissions. Thus, it is important for providers to understand how the LSA score of a patient compares to the general population. To facilitate such comparisons, we developed demographically adjusted norms for the LSA and its correlation with other functional measures. Norms were based on 15,390 participants age 45 and older in the National Institutes of Health-funded REasons for Geographic and Racial Differences in Stroke (REGARDS) study, a national, population-based, longitudinal study investigating the causes of excess stroke mortality among African Americans and individuals living in the Southeastern US stroke belt region. LSA scores declined from a median of 100 in the 45-54 age range to a median of 59.7 in the 85 and older age range, with higher median scores in males. LSA scores showed modest but significant positive correlations with SF-12 Physical Component and Mental Component, Center for Epidemiologic Studies Depression Scale, and Six Item Screener cognitive scores, as well as modest but significant negative correlations with AD8 Dementia Screening, Katz Activities of Daily Living, and Timed Walk scores. The LSA is a brief, easily administered measure that offers a valid method of assessing community mobility in the older adult population.

Community Mobility

Abstract Community mobility is an individual’s movement outside the home. It is essential for the completion of many instrumental activities of daily living, such as shopping and healthcare, and promotes physical function, social engagement, independent living, and quality of life. Mobility research often focuses on gait speed measured in clinical settings, a critical but not sufficient determinant of community mobility. Here we present four talks that assess community mobility and its determinants using novel methodologies to enhance our understanding of how to maintain independence in older ages. First, Andrea Rosso presents characteristics of individuals with the strongest associations between environmental walkability, as assessed by virtual audits, and walking. Second, Kyle Moored demonstrates associations of self-reported fatigability with life space among older men, independent of their physical functioning. Breanna Crane introduces GPS-based objective measures of community mobility and their associations with cognitive and physical function of older adults. Finally, Pam Dunlap presents results of a randomized clinical trial of a physical therapy intervention to improve walking in older adults on subjective and objective measures of life space. These talks will provide a better understanding of the factors related to community mobility, introduce attendees to novel methodologies in the assessment of both community mobility and risk factors associated with the loss of community mobility, and demonstrate approaches to improve community mobility in at-risk older adults. The discussant, Jana Hirsch, will provide perspectives on how these data inform our current view of community mobility and will lead a discussion with the audience.

Background: Absolute grip strength (aGS) is used to detect dynapenia, and is also an indicator of functional impairments such as mobility limitations. The objective of this study is to investigate whether dynapenia status assessed by absolute grip strength (aGS) is associated with loss of community mobility.Method: The population studied (n=62) was composed of a dynapenic group of women (aged 66.4 ± 4.8) according to an aGS threshold of ≤ 19.9kg and an age-matched group of nodynapenic women (aged 66.1 ± 5.2). The aGS was measured and body-weigth-related to grip strength (BW/GS) was computed. Fonctionnal laboratory tests were conducted. During 12 days, each participant wore a GPS device to obtain Transit distance in vehicle per day, Transit distance on foot per day and Ellipse area. The Life space (LS) was assessed using the Life Space Assesment questionnaire (LSA). A Wilcoxon test was used to compare the 2 groups for the community mobility measures. Then, data of the 2 groups were pooled to assess the relationship between BW/GS and community mobility measures. A Spearman correlation was used.Results: The dynapenic group performed worse for fonctionnal capacity tests such as the step test and the walking speed. Howerver, no significant difference was found for GPS measures and LS between the two groups. No significant relationship was found for the BW/GS and community mobility measures with the GPS measures and the LS.
