Using the Transtheoretical Model of Change to Implement Home Safety Modifications with Community-Dwelling Older Adults: An Exploratory Study Martina C. McNulty, PhD, OTR/L Jayme Johnson, MOT, OTR/L Janet L. Poole, PhD, OTR/L Melissa Winkle ABSTRACT. Objective: This exploratory study examined the viability of applying Prochaska’s Transtheoretical Model (TTM) to community-liv- ing older adults making home safety changes over time. Method: The Readiness for Change (RFC) interview and the Westmead Home Safety Assessment were administered to 20 community-dwelling older adults. Eight to twelve weeks later, a follow-up home visit was made to determine how many home safety modifications had been im- plemented. Results: Participants in the action-related stages (i.e., action and maintenance stages) implemented significantly more home modifica- tions than participants in the non-action stages (i.e., precontemplation, contemplation, and preparation stages, F(1,18) = 7.7; p  0.01. Conclusion: The readiness for change model was a useful approach to Martina C.
