Fidelity and utility of GPS loggers as a tool for understanding community participation of older adults

Abstract

Objective The purpose of this research was to examine the fidelity and utility of global positioning system (GPS) technology for studying community mobility indicators, and to explore implications for community participation for older adults. Method A longitudinal cohort design with community-dwelling older adults (n = 33) was employed. GPS spatial data and activity logs were collected at baseline and one year later. Data were analysed to evaluate the fidelity of the GPS protocol, the nature and frequency of destinations, and the stability of community mobility over time. Results Findings include evidence for high reliability of the GPS loggers to record out-of-home trips when compared to activity logs; utility of the technology for identifying frequency and type of occupational destinations; and the relative stability of two community mobility variables over time. GPS loggers generate key insights into how older adults move in and through their community as they engage in a range of occupations. Conclusion GPS technology is a robust and useful tool for gathering novel information, especially when combined with qualitative data. GPS loggers may be incorporated in evaluation or to tailor interventions. Community mobility enables social participation, and warrants further research using these methods to support processes of aging in place.
