Background: Older adults experiencing disabilities such as frailty and loss of autonomy face the decision of whether to stay at home or move to a healthcare facility such as skilled nursing care facilities. Thus, they may need support for this difficult decision. Objective: We assessed Canadian older adults’ intention to use an electronic decision aid (eDA) for making housing decisions and identified the factors that influenced their intention. Methods: We conducted a cross-sectional study using an online survey targeting older adults across the 10 Canadian provinces and 3 territories. We adapted 17 Unified Theory of Acceptance and Use of Technology (UTAUT) items to measure respondents’ intention to use the eDA for housing decisions, as well as items measuring intention constructs. We also assessed e-Health literacy using subjective and Objective scales. We used descriptive statistics and multivariate linear regression analyses to identify factors influencing the intention to use the eDA. Results: Of the 1,176 who met the eligibility criteria, 1,000 respondents completed the survey. The mean age was 72.5 ± 5.59 years. Most respondents were male, white, English-speakers and living in Ontario or Quebec in urban areas. Mean scores for subjective e-Health literacy were 27.8 ± 5.88 out of 40 and for Objective e-Health literacy, 3.00 ± 0.973 out of 5. In our sample, the intention score was 4.74 ± 1.7 out of 7. In the final model, factors associated with intention included mother tongue, e-Health literacy, performance expectancy, social influence and facilitating conditions. Conclusions: Findings from this pan-Canadian online survey suggest that Canadian older adults’ intention to use an eDA to make housing decisions are similar to Findings in other studies using UTAUT. Factors identified as influencing intention will guide future strategies for implementing the eDA.
