人们对行政职能的结构和相互关系越来越感兴趣。本研究考察了Delis Kaplan执行功能系统（D-KEFS）的因素结构以及与年龄相关的因子不变性，D-KEFS是一种广泛使用的旨在评估执行功能的量表。首先使用D-KEFS技术手册中提供的数据进行分析，然后在11至16岁的男性早期青少年的独立样本中进行重复分析。结果显示，三因素解决方案最适合跨组和样本的数据；测量属性似乎在不同年龄组中对某些负荷是不变的，而对其他负荷是不同的。这三个因素被标记为概念灵活性，监控和抑制。这些发现有助于更好地理解D-KEFS的测量特性，并有助于对旨在评估执行功能的测量结构进行更广泛的研究。
There has been an increased interest in the structure of and relations among executive functions. The present study examined the factor structure as well as age-related factorial invariance of the Delis Kaplan Executive Function System (D-KEFS), a widely used inventory aimed at assessing executive functions. Analyses were first conducted using data provided in the D-KEFS technical manual and were then replicated in an independent sample of male early adolescents aged 11 to 16 years. Results revealed a three-factor solution best fit the data across groups and samples; measurement properties appeared to be invariant across age groups for certain loadings and variant for others. The three factors were labeled Conceptual Flexibility, Monitoring, and Inhibition. These findings provide better understanding of the measurement properties of the D-KEFS and contribute to the larger literature on the structure of measures intended to assess executive functions.
