Background
Map-based tools have recently found their way into health-related research. They can potentially be used to quantify older adults’ life-space. This study aimed to evaluate the validity (vs. GPS) and the test-retest reliability of a map-based life-space assessment (MBA).
Methods
Life-space of one full week was assessed by GPS and by MBA. MBA was repeated after approximately 3 weeks. Distance-related (mean and maximum distance from home) and area-related (convex hull, standard deviational ellipse) life-space indicators were calculated. Intraclass correlations (MBA vs. GPS and test-retest) were calculated in addition to Bland-Altman analyses (MBA vs. GPS).
Results
Fifty-eight older adults (mean age 74, standard deviation 5.5 years; 39.7% women) participated in the study. Bland-Altman analyses showed the highest agreement between methods for the maximum distance from home. Intraclass correlation coefficients ranged between 0.19 (95% confidence interval 0 to 0.47) for convex hull and 0.72 (95% confidence interval 0.52 to 0.84) for maximum distance from home. Intraclass correlation coefficients for test-retest reliability ranged between 0.04 (95% confidence interval 0 to 0.30) for convex hull and 0.43 (95% confidence interval 0.19 to 0.62) for mean distance from home.
Conclusions
While acceptable validity and reliability were found for the distance-related life-space parameters, MBA cannot be recommended for the assessment of area-related life-space parameters.

Skantz, Heidi; Rantanen, Taina; Rantalainen, Timo; Keskinen, Kirsi E.; Palmberg, Lotta; Portegijs, Erja; Eronen, Johanna; Rantakokko, Merja (SAGE Publications, 2020)Objectives: To examine associations of perceived outdoor environment with the prevalence and development of adaptive (e.g., slower pace) and maladaptive (e.g., avoiding walking) modifications in walking 2 km among older ... -
Older Adults’ Self-Reported Physical Activity and Distance to and Land Use Around Reported Physical Exercise Destinations
Tuomola, Essi-Mari; Keskinen, Kirsi E.; Hinrichs, Timo; Rantanen, Taina; Portegijs, Erja (Human Kinetics, 2023)Little is known about older adults’ physical exercise destinations. We studied associations between physical activity (PA) level and physical exercise destinations (total number and surrounding environment) in community-dwelling ... -
