- Background: Mobility is a vitally important activity throughout life. Advanced age carries increased risk of experiencing decreased mobility, with associated activity limitations and participation restrictions in social events. The Life-Space Assessment (LSA), originally developed by Sawyer Baker and colleagues in the U.S.A., has been used to measure mobility in community dwelling older adults. The LSA includes six levels of life-space, ranging from the person's bedroom to places beyond the person's hometown. A total LSA score is obtained by multiplying the life-space level reached by a value for independence and a value for the frequency of transportations. Three additional measures of life-space levels can be calculated: the independent life-space level; the assistive life-space level; and the maximal life-space level. Objective: To examine the test-retest reliability of the Swedish version of the Life-Space Assessment Questionnaire. Methods: At two test sessions, two weeks apart, 298 community-dwelling subjects between 75 and 90 years of age were asked about their life-space mobility during the past four weeks, and how often and whether they were independent from another person or equipment to reach different life-space levels. Results: None of the four scoring methods showed significant differences between test sessions. The mean total scores were 65 out of the maximum possible score of 120 at both test sessions. High levels were also found for independent, assisted, and maximal life-space at both sessions. ICC coefficients and weighted Kappa values between 0.84-0.94 were found for the total score, the independent and the assisted life-space levels indicating good to excellent reliability. The method error values showed that a change of 10 in the total score and a change of one level in any of the three life-space levels can be considered to indicate a real change in clinical practice. Conclusion: The Swedish version of the Life-Space Assessment Questionnaire can be reliably used among community-dwelling older adults.
