Feasibility Trial of Tailored Home Modifications: Process Outcomes.

Objective: The aim of this study was to conduct a process evaluation to examine the implementation of a randomized controlled trial of home modifications designed to reduce the risk of falls and improve daily activity performance among community-dwelling older adults.

Method: A process evaluation was conducted alongside a blinded, randomized sham-controlled trial (n = 92). Participants were followed for 1 yr after intervention. The process evaluation was framed using the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework.

Results: The treatment group improved daily activity performance over 12 mo compared with the sham control group (F = 4.13; p = .024). The intervention elements and dose were delivered with greater than 90% accuracy. Participants reported a 91% adherence rate at 12 mo.

Conclusion: The complex intervention of home modifications examined in this study is acceptable to older adults, is feasible, and can be delivered with high fidelity for frail, community-dwelling older adults.
