The purpose of this study was to examine the utility of specific tests of executive functioning for predicting instrumental activities of daily living (IADLs) in community-dwelling older individuals (n = 30). In addition to tests of frontal and executive functioning, performance-based and caregiver-rated evaluations of IADLs were obtained. Results indicated that different tests of executive functioning were associated with outcomes on performance-based versus caregiver-rated assessments of IADLs. Specifically, the Trail Making Test (Part B) made a significant and unique contribution to the prediction of performance-based IADLs. In contrast, verbal fluency performance and Trail Making Test performance made significant independent contributions to the prediction of IADLs as reported by a caregiver. These findings suggest that different aspects of frontal and executive functions may be related to IADLs, depending on the type of assessment instrument used. Key words: activities of daily living, executive function, older adults
本研究的目的是检验执行功能的特定测试对于预测社区居住的老年人（n = 30）的日常生活工具性活动（IADL）的效用。除了额叶和执行功能测试外，还获得了基于表现的IADL评估以及照顾者评定的评估。结果表明，执行功能的不同测试与基于表现的IADL评估和照顾者评定的评估结果相关。具体而言，连线测验（B部分）对基于表现的IADL预测做出了显著且独特的贡献。相比之下，言语流畅性表现和连线测验表现对照顾者报告的IADL预测做出了显著的独立贡献。这些发现表明，额叶和执行功能的不同方面可能与IADL相关，这取决于所使用的评估工具类型。关键词：日常生活活动、执行功能、老年人
