Background and objectives: Recent critical evaluations of age-friendly efforts have highlighted the need to prioritize the disenfranchised, including people with mobility limitations. This article examines the validity of a 13-item Stakeholders Walkability/Wheelability Audit in Neighborhoods (SWAN13) scale to measure the "walk/wheelability" of street segments from the perspectives of people with mobility limitations.
Research design and methods: Data were drawn from preliminary studies of the SWANaudit which was conducted in 2 Canadian metropolitan areas. Sixty-one participants who use mobility devices (e.g., walkers, power wheelchairs) and older adults from community organizations audited 195 street segments. We factor analyzed the data from their audits.
Results: SWAN13 has a 1-factor structure. 13 items were retained from 85 SWANaudit items. SWAN13 encompassed both physical and social aspects of walk/wheelability. The alpha for the scale was .79. Convergent validity was found with the University of Alabama Life-Space Assessment (ρ = .22, p = .003), especially at the neighborhood level (ρ = .23, p = .002). Significant correlation was also found with subjective assessments of a priori walk/wheelability domains (ρ = .63, p < .001).
Discussion and implications: Walk/wheelability affects the life space of older adults and people with mobility limitations. It is an important latent variable that should be addressed to promote well-being and social participation. SWAN13 may be used in city-wide surveys to identify neighborhoods that may require age-friendly interventions from mobility perspectives. Detailed audits and interventions may be carried out in tandem using the paired SWANaudit instrument. Walk/wheelability is an inclusive and measurable concept that accounts for the needs of people with various mobility needs.
