OBJECTIVES: Based on previous empirical research on financial stressors and resources and using a prevention science framework, this pilot study examined the effect and acceptability of a three-session older adult financial exploitation prevention intervention. METHODS: Forty-five older adults participated in the study. Each participant completed three 30- to 45-minute sessions. The sessions included financial exploitation vulnerability, financial literacy, techniques used by scammers, choosing a trusted advocate, and creating a financial inventory. At the end of each session, participants were asked how relevant and trustworthy the information presented was. Primary outcome measures were financial vulnerability and financial literacy. Secondary outcomes were other mental health and stress factors, as well as how many participants reported choosing a trusted advocate and creating a financial inventory. RESULTS: Financial literacy and financial vulnerability scores after the prevention intervention differed significantly from baseline scores. Participants' ratings after each session, with respect to usefulness and trustworthiness, were extremely positive. CONCLUSIONS: The financial exploitation prevention intervention program demonstrated acceptability and a positive effect on reducing vulnerability to financial exploitation. CLINICAL IMPLICATIONS: Proper assessment of an older client's financial history and of plans to safeguard their financial future is integral to the overall well-being and health of older clients.
