Abstract

The Barkley Deficits in Executive Functioning Scale – Short Form (BDEFS-SF; Barkley, 2011 Barkley, R. A. (2011). Barkley deficits in executive functioning scale (BDEFS). Guilford. [Google Scholar]) was developed to assess deficits in five facets of executive functioning. Theoretical assumptions surrounding the BDEFS-SF presume that executive dysfunction is an overarching construct that consists of five domain-specific factors (i.e., a hierarchical model; Barkley, 2011 Barkley, R. A. (2011). Barkley deficits in executive functioning scale (BDEFS). Guilford. [Google Scholar]). Prior research has supported a correlated five-factor model, but the tenability of hierarchical or bifactor models of the BDEFS-SF have not yet been tested. In the present study (N = 1,120 community adults), confirmatory factor analysis was used to compare four theoretically relevant models of the BDEFS-SF (i.e., one-factor, correlated five-factor, hierarchical, and bifactor models). The bifactor model provided the best fit to the data. However, the general factor accounted for the overwhelming majority of variance in BDEFS-SF scores and none of the domain-specific factors exhibited adequate construct replicability or factor determinancy. Further, the general factor accounted for the overhelming majority of variance in criterion variables (i.e., executive attention and health anxiety); the Organization and Emotion factors accounted for a small amount of unique variance in executive attention and the Emotion factor accounted for a small amount of unique variance in health anxiety. Taken together, study findings suggest that the BDEFS-SF has a strong general factor and independent use of the domain-specific factors is contraindicated.

摘要

执行功能量表中的巴克利缺陷 - 简表（BDEFS-SF；巴克利，2011 年） 巴克利，RA（2011 年）。巴克利执行功能量表 (BDEFS) 缺陷。吉尔福德。 [Google Scholar] ) 旨在评估执行功能五个方面的缺陷。围绕 BDEFS-SF 的理论假设假定执行功能障碍是一个由五个特定领域因素组成的总体结构（即，层次模型；Barkley，2011 巴克利，RA（2011 年）。巴克利执行功能量表 (BDEFS) 缺陷。吉尔福德。 [谷歌学术]）。先前的研究支持相关的五因素模型，但 BDEFS-SF 的分层或双因素模型的有效性尚未经过测试。在本研究中（N = 1,120 名社区成人），使用验证性因子分析来比较 BDEFS-SF 的四种理论相关模型（即，单因素、相关五因素、分层和双因素模型）。双因子模型为数据提供了最佳拟合。然而，一般因素占 BDEFS-SF 分数差异的绝大多数，并且没有任何特定领域的因素表现出足够的结构可重复性或因素决定性。此外，一般因素解释了标准变量（即执行注意力和健康焦虑）中绝大多数的差异；组织和情绪因素在执行注意力中占了少量的独特方差，情绪因素在健康焦虑中占了少量的独特方差。综合起来，
