执行过程中的困难会干扰日常生活功能。使用来自两个独立社区居住样本(n（1)=468, n(2)=669, 18-97岁）的数据，我们检查了执行障碍功能问卷（DEX）的因素结构，并探讨了自我报告执行困难的频率和潜在相关性。我们的研究结果表明，执行问题是用一个潜在的因素来简洁地描述的。在整个成年期，日常执行功能障碍的发生率中等。执行问题的报告与个体差异特征有关，包括年龄、主观健康、个性、情感和认知。我们还发现，虽然执行功能随着年龄的增长而下降，但年轻人比老年人报告的问题更多，这种影响部分由负面影响因素介导。我们讨论了对该工具有效性的影响，以及对日常生活中执行功能困难的未来研究方向。
Difficulties in executive processes can disturb daily life functioning. Using data obtained from two independent community-dwelling samples (n(1)=468, n(2)=669, 18-97 years), we examined the factor structure of the Dysexecutive Functioning Questionnaire (DEX) and explored the frequencies and potential correlates of self-reported executive difficulties. Our results revealed that executive problems are parsimoniously described with one underlying factor. Everyday executive dysfunctions were moderately frequent throughout adulthood. Reports of executive problems were associated with individual difference characteristics including age, subjective health, personality, affect, and cognition. We also found that, although executive functions are known to decline with advancing adult age, younger age groups reported more problems than older groups, an effect that was partially mediated by a negative affect factor. We discuss implications for the validity of the instrument as well as directions for future research on executive functioning difficulties in everyday life.
