Abstract

The parent-report Behavior Rating Inventory of Executive Function, Second Edition (BRIEF-2) is a widely used pediatric neuropsychological measure. Unfortunately, despite meaningful changes from its predecessor, few studies have examined its internal factor structure (now with Behavioral Regulation [BRI], Emotion Regulation [ERI], and Cognitive Regulation [CRI]), and no available literature has investigated higher order models for the BRIEF-2. This study sought to address this shortcoming in the literature by investigating and reporting on the dimensionality of the parent-report BRIEF-2 in a clinical sample. Two hundred and two (202) pediatric neuropsychology examinees (M age = 9.90; 68% males) with complete data for the parent-report BRIEF-2 were included. Descriptive results revealed generally elevated scores across BRIEF-2 scales (Global Executive Composite M T = 70.16). Exploratory factor analyses suggested two factors (CRI and BRI/ERI) should be extracted, and that higher order models should be considered. Confirmatory factor analyses suggested that a direct hierarchical/bifactor two-factor structure (which was more parsimonious than the theoretical three-factor model) provided the best fit, with a bulk of the variance explained by the general GEC factor. The BRIEF-2 may be best interpreted at the overall level, with relatively less weight given to the index variables, particularly within clinical samples with high levels of reported executive functioning difficulties. Implications of these findings, limitations of the present study, and appropriate directions for future inquiry were discussed.

摘要

父母报告执行功能行为评定量表，第二版 (BRIEF-2) 是一种广泛使用的儿科神经心理学测量方法。不幸的是，尽管它的前身发生了有意义的变化，但很少有研究检查其内部因素结构（现在有行为调节 [BRI]、情绪调节 [ERI] 和认知调节 [CRI]），并且没有可用的文献研究高阶模型简介-2。本研究试图通过调查和报告临床样本中父报告BRIEF-2的维度来解决文献中的这一缺陷。两百零二（202）名小儿神经心理学考生（男年龄 = 9.90；68% 的男性）具有完整的父母报告 Brief-2 的数据。描述性结果显示，BRIEF-2 量表的得分普遍较高（全球高管综合MT = 70.16)。探索性因素分析表明应该提取两个因素（CRI 和 BRI/ERI），并且应该考虑更高阶的模型。验证性因子分析表明，直接分层/双因子双因子结构（比理论三因子模型更简洁）提供了最佳拟合，大部分方差由通用 GEC 因子解释。Brief-2 可能在整体水平上得到最好的解释，指数变量的权重相对较小，特别是在报告的执行功能困难水平较高的临床样本中。讨论了这些发现的含义、本研究的局限性以及未来调查的适当方向。
