Objective Previous research suggests that overall experience participating in instrumental activities of daily living (IADLs) is associated with reduced IADL impairment in individuals with mild cognitive impairment, possibly because of an increased functional reserve. Given that difficulties managing finances tend to occur with mild cognitive impairment, this study explores whether experience managing one's finances is associated with independence across various IADLs. Methods Participants with a screen or baseline diagnosis of mild cognitive impairment (n = 862) were taken from the Alzheimer's Disease Neuroimaging Initiative study. Functional dependence and experience were quantified from the Functional Activities Questionnaire. Results No group differences between those with and without financial management experience existed in Mini‐Mental State Examination scores, age, and years of education, although women were more likely to have experience managing finances (P < .001). Final chi‐square analyses suggest that financial management experience is significantly associated with greater independence in the ability to follow TV, books, or magazines (P = .009) and remember appointments and important dates (P = .002). Conclusions Individuals who are rated as having experience in managing their finances were also rated as being less dependent in their ability to follow and understand TV and books and in their ability to remember appointments and important dates. Neither causation nor the mechanisms underlying this relationship can be discerned from these analyses. Therefore, further research is needed to investigate whether engaging in financial tasks protects against early financial impairment, potentially through an increased functional reserve.
