Key summary points
To validate the “Life-Space Assessment in Persons with Cognitive Impairment” (LSA-CI) to assess mobility within the environment including contextual factors in older persons without cognitive impairment.
AbstractSection FindingsExcellent feasibility with 100% completion rate and average assessment duration of 4 min in 65 older persons. The LSA-CI composite score stood out with moderate to high construct validity, excellent test–retest reliability and moderate sensitivity to change. Analysis of sub-scores confirmed most of the composite score results.
AbstractSection MessageThe LSA-CI represents a valid, reliable, responsive, and highly feasible assessment method in multi-morbid, older persons without cognitive impairment, and can be recommended for use in clinical practice and research.
Abstract
Purpose
The “Life-Space Assessment in Persons with Cognitive Impairment” (LSA-CI) to assess mobility within the environment including frequency and independence in 1 week has been developed for and successfully validated in older persons with mild to moderate cognitive impairment. However, its psychometric properties in persons without cognitive impairment are unknown. This study aims to validate the LSA-CI in older persons without cognitive impairment.
Methods
Comprehensive validation with construct validity, test–retest reliability and sensitivity to change of the LSA-CI including the main composite score and three sub-scores in community-dwelling older persons recruited during geriatric rehabilitation.
Results
Excellent feasibility with 100% completion rate and an average assessment duration of 4 min in 65 older, multimorbid persons (mean age: 81.4 ± 5.9 years; 72.3% female; average number of diagnoses: 11.1 ± 4.4). The LSA-CI composite score stood out with moderate to high construct validity (Spearman correlation coefficients |0.26|–|0.60|), excellent test–retest reliability (intraclass correlation coefficient 0.890) and moderate sensitivity to change (adjusted standardized response mean 0.70). Analysis of sub-scores confirmed most of the composite score results.
Conclusions
The LSA-CI represents a valid, reliable, responsive, and highly feasible assessment method in multi-morbid, older persons without cognitive impairment, supporting the use of the LSA-CI in clinical practice and research.
