Background: The Senior Walking Environmental Assessment Tool (SWEAT), an instrument for measuring built environmental features associated with physical activity of older adults, was revised to create an easier-to-use tool for use by practitioners and community members.
Methods: Inter-rater and intra-rater reliability of the modified instrument (SWEAT-R) was assessed in Portland, Oregon in 2007. Five trained observers audited street segments in 12 neighborhoods, resulting in 361 pairs of audits, including 63 repeated audits.
Results: Overall, 88% and 75% of items assessed had good or excellent inter-rater and intra-rater reliability, respectively. The revised instrument required less time to complete than the original instrument, while obtaining more information.
Conclusion: SWEAT-R provides easy to gather, reliable data for use in community-based audits of built environment in relation to walking among older adults.
