Validation of the Indian (Hindi) version of the life-space assessment scale among community-dwelling older adults: a multicentric cross-sectional study. BMC Geriatr 2024; 24:500. [PMID: 38844833 PMCID: PMC11157764 DOI: 10.1186/s12877-024-05072-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Accepted: 05/13/2024] [Indexed: 06/09/2024] Open
Abstract
BACKGROUND The Life-Space Assessment (LSA) is an instrument that measures mobility in older adults as they reach different areas, defined as life-spaces extending from home to beyond towns or regions. The purpose of the study was to develop the Hindi version of the LSA (LSA- H) and to investigate the validity and reliability of the Hindi version as well as its cultural adaptation. METHODS A cross-sectional study of two hundred forty-five older adults participated in the study from four different study practice areas. Following forward backwards translation, the LSA-H was developed, and the scores were correlated with those of the Activities-Specific Balance Confidence Scale Hindi (ABC- H), the Physical Health Subscale of the WHO-BREF Questionnaire and the Geriatric Depression Scale: Short Form Hindi (GDS-SFH) to test the criterion and concurrent validity. RESULTS The mean score and standard deviation of the LSA-H questionnaire were 56.53 ± 35.99, those of the Physical Health Subscale of the WHO-BREF instrument were 18.54 ± 7.87, those of the GDS-SFH questionnaire were 6.95 ± 4.21 and those of the ABC- H questionnaire were 54.40 ± 28.96. The Pearson correlation coefficient (r) between the LSA-H score and ABC-H score was 0.707 (p value < 0.0001), that between the LSA-H score and the Physical Health Subscale of the WHO-BREF was 0.766 (p value < 0.0001), and that between the LSA-H score and GDS-SFG score was - 0.674 (p value < 0.0001). CONCLUSION This study demonstrated that the Hindi version of the LSA is a valid and reliable instrument for assessing living space among older adults in the Hindi language in an Indian population. Furthermore, the LSA-H was significantly correlated with other health assessment tools in terms of functional mobility, general health status and mental well-being.

THE GERONTOLOGIST 2024; 64:gnad038. [PMID: 37014063 DOI: 10.1093/geront/gnad038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Indexed: 04/05/2023] Open
Abstract
BACKGROUND AND OBJECTIVES The life-space assessment (LSA) is the most commonly used questionnaire to assess life-space mobility (LSM) in older adults, with well-established psychometric properties for face-to-face (FF) administration. However, these properties have not yet been explicitly studied when the LSA is administered by telephone. The aim of this study was to evaluate the concurrent and construct validity, test-retest reliability, responsiveness, and feasibility of a telephone-based LSA version (TE-LSA) in older adults. RESEARCH DESIGN AND METHODS Fifty community-dwelling older adults (age = 79.3 ± 5.3 years) participated in the study. Concurrent validity was assessed against the FF-LSA construct validity by testing 15 a priori hypotheses on expected associations with LSM determinants, test-retest reliability via 2 telephone surveys 1 week apart, responsiveness after 8.5 ± 1.8 months in participants with improved, stable, and worsened mobility defined by 2 external criteria, and feasibility by the completion rate/time and ceiling/floor effects. RESULTS Good to excellent agreement between the 2 different administration methods was found (intraclass correlation coefficient [ICC2,1] = 0.73-0.98). Twelve of 15 (80%) hypotheses on construct validity were confirmed. ICCs for test-retest reliability were good to excellent (ICC2,1 = 0.62-0.94). Minimal detectable change for the TE-LSA total score was 20 points. Standardized response means were large for worsened (0.88), moderate for improved (0.68), and trivial for stable participants (0.04). Completion rate was 100% and mean completion time was 5.5 ± 3.3 min. No ceiling or floor effects were observed for the TE-LSA total score. DISCUSSION AND IMPLICATIONS Telephone administration of the LSA is valid, reliable, responsive, and feasible for assessing LSM in community-dwelling older adults.

Self-reported life-space mobility in the first year after ischemic stroke: longitudinal findings from the MOBITEC-Stroke project. J Neurol 2023:10.1007/s00415-023-11748-5. [PMID: 37140729 PMCID: PMC10157571 DOI: 10.1007/s00415-023-11748-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/24/2023] [Accepted: 04/26/2023] [Indexed: 05/05/2023]
Abstract
BACKGROUND Life-space mobility is defined as the size of the area in which a person moves about within a specified period of time. Our study aimed to characterize life-space mobility, identify factors associated with its course, and detect typical trajectories in the first year after ischemic stroke. METHODS MOBITEC-Stroke (ISRCTN85999967; 13/08/2020) was a cohort study with assessments performed 3, 6, 9 and 12 months after stroke onset. We applied linear mixed effects models (LMMs) with life-space mobility (Life-Space Assessment; LSA) as outcome and time point, sex, age, pre-stroke mobility limitation, stroke severity (National Institutes of Health Stroke Scale; NIHSS), modified Rankin Scale, comorbidities, neighborhood characteristics, availability of a car, Falls Efficacy Scale-International (FES-I), and lower extremity physical function (log-transformed timed up-and-go; TUG) as independent variables. We elucidated typical trajectories of LSA by latent class growth analysis (LCGA) and performed univariate tests for differences between classes. RESULTS In 59 participants (mean age 71.6, SD 10.0 years; 33.9% women), mean LSA at 3 months was 69.3 (SD 27.3). LMMs revealed evidence (p ≤ 0.05) that pre-stroke mobility limitation, NIHSS, comorbidities, and FES-I were independently associated with the course of LSA; there was no evidence for a significant effect of time point. LCGA revealed three classes: "low stable", "average stable", and "high increasing". Classes differed with regard to LSA starting value, pre-stroke mobility limitation, FES-I, and log-transformed TUG time. CONCLUSION Routinely assessing LSA starting value, pre-stroke mobility limitation, and FES-I may help clinicians identify patients at increased risk of failure to improve LSA.

Abstract
BACKGROUND Stroke is a common cause of mobility limitation, including a reduction in life space. Life space is defined as the spatial extent in which a person moves within a specified period of time. We aimed to analyze patients' objective and self-reported life space and clinical stroke characteristics. METHODS MOBITEC-Stroke is a prospective observational cohort study addressing poststroke mobility. This cross-sectional analysis refers to 3-month data. Life space was assessed by a portable tracking device (7 consecutive days) and by self-report (Life-Space Assessment; LSA). We analysed the timed up-and-go (TUG) test, stroke severity (National Institutes of Health Stroke Scale; NIHSS), and the level of functional outcome (modified Rankin Scale; mRS) in relation to participants' objective (distance- and area-related life-space parameters) and self-reported (LSA) life space by multivariable linear regression analyses, adjusted for age, sex, and residential area. RESULTS We included 41 patients, mean age 70.7 (SD11.0) years, 29.3% female, NIHSS score 1.76 (SD1.68). We found a positive relationship between TUG performance and maximum distance from home (p = 0.006), convex hull area (i.e. area enclosing all Global Navigation Satellite System [GNSS] fixes, represented as a polygon linking the outermost points; p = 0.009), perimeter of the convex hull area (i.e. total length of the boundary of the convex hull area; p = 0.008), as well as the standard ellipse area (i.e. the two-dimensional ellipse containing approximately 63% of GNSS points; p = 0.023), in multivariable regression analyses. CONCLUSION The TUG, an easily applicable bedside test, seems to be a useful indicator for patients' life space 3 months poststroke and may be a clinically useful measure to document the motor rehabilitative process.

[PMID: 36707541 PMCID: PMC9883526 DOI: 10.1038/s41598-023-28636-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Accepted: 01/23/2023] [Indexed: 01/28/2023] Open
Abstract
The present study examined the psychometric properties of the 12-item Stroke-Specific Quality of Life Scale (SSQOL-12) in 184 stroke survivors in Hong Kong. The participants completed a self-report questionnaire including the SSQOL-12, SF-12 health survey, and validating variables at baseline and 148 stroke survivors completed SSQOL-12 two months later. Confirmatory factor analysis investigated the construct validity, reliability, and measurement invariance of SSQOL-12 across two months. Concurrent, convergent, and divergent validity was examined with respect to SF-12, hope, self-esteem, functional disability, anxiety, and depression. The original 2-factor model did not reveal a superior fit over the 1-factor model and a modified 1-factor model provided an acceptable fit to the data in both waves. The SSQOL-12 factor displayed substantial factor loadings (λ = 0.40-0.87), good internal consistency (Ω = 0.88), temporal stability (r = 0.70), and scalar measurement invariance across time. Stroke-specific quality of life was significantly associated with higher levels of SF-12, hope, and self-esteem and lower levels of functional disability, anxiety, and depression. Most correlations remained significant after controlling for demographic covariates and SF-12. The present findings offered empirical support for the validity and reliability of the unidimensional structure for SSQOL-12 as a measure of stroke-specific quality of life among stroke survivors.
