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.
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.
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).
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.
先前的研究表明，参与日常生活工具性活动（IADL）的总体体验与轻度认知障碍个体的IADL损伤减轻有关，这可能是由于功能储备增加所致。鉴于财务管理困难往往与轻度认知障碍相伴出现，本研究探讨财务管理经验是否与各项IADL的独立性相关。
从阿尔茨海默病神经影像学倡议研究中选取筛查或基线诊断为轻度认知障碍的参与者（n = 862）。通过功能活动问卷对功能依赖性和体验进行量化。
在简易精神状态检查表得分、年龄和受教育年限方面，有财务管理经验者和无财务管理经验者之间不存在组间差异，不过女性更有可能有财务管理经验（P <.001）。最终的卡方分析表明，财务管理经验与在看电视、阅读书籍或杂志（P =.009）以及记住预约和重要日期方面具有更高的独立性显著相关（P =.002）。
被评定有财务管理经验的个体在看电视、理解书籍以及记住预约和重要日期的能力方面也被评定为依赖性较低。从这些分析中无法辨别因果关系或这种关系背后的机制。因此，需要进一步研究来调查参与财务任务是否可能通过增加功能储备来预防早期财务损伤。
