Home Usability for Older Adults: Results from the Dwelling Usability for Equitable Living (DUEL^©) Survey

One’s housing must align with personal competencies/abilities, needs, and preferences to age-in-place. The Dwelling Usability for Equitable Living (DUEL^©) Survey was developed to subjectively assess home spaces. Adults (N = 504; aged 40-92) responses to the DUEL^© were analyzed using exploratory factor analyses and principal axis factoring with maximum likelihood extraction. DUEL^© space-specific subscales demonstrated good-excellent suitability (KMO range = 0.62-0.92) and accounted for 50.4-70.4% of the variance. Reliability ranged from α = 0.66-0.93. Subscales indicated two-three factors (i.e., Perceived In/Effectiveness, Perceived In/Efficiency, and dys/functionality (kitchen)). The DUEL^© Survey demonstrates good utility as a measure of home usability and captures multidimensional perceptions of one’s home spaces.
