Abstract

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.
