The present study aims to analyze, on the one hand, the dimensional structure of the BRIEF-2 and, on the other, its measurement invariance across gender in a sample of primary school-aged children. Participants were 168 students (51.8% girls) in conditions of social risk and in foster homes, with ages ranging from 6 to 15 years old (M = 10.08; SD = 2.09). The children's executive functioning level was obtained from their parents or caregivers. The analysis of the internal structure using confirmatory factor analysis reveals that the model with three indexes (Behavioral, Emotional and Cognitive) and nine scales (Inhibit, Shift, Self-Monitor, Emotional Control, Initiate, Working Memory, Plan/Organize, Organization of Materials and Task-Monitor) showed a good fit to the sample. Likewise, the results support the measurement invariance of the BRIEF-2 across genders. The coefficient alpha values for the index scores ranged from .71 to .91, with coefficients for the individual scales ranging from .66 to .88. The findings support the factorial validity of the BRIEF-2 scores, suggesting that it is an adequate instrument to evaluate executive functioning reported by parents and caregivers. Future studies must continue to examine the structure and invariance of the BRIEF-2 in different populations and cultures.
本研究旨在一方面分析BRIEF-2的维度结构，另一方面分析其在小学适龄儿童样本中跨性别的测量不变性。研究参与者为168名处于社会风险状况且生活在寄养家庭中的学生（51.8%为女孩），年龄在6至15岁之间（M = 10.08；SD = 2.09）。儿童的执行功能水平通过其父母或照料者获得。使用验证性因素分析对内部结构进行分析后发现，具有三个指标（行为、情绪和认知）和九个分量表（抑制、转换、自我监控、情绪控制、发起、工作记忆、计划/组织、材料组织和任务监控）的模型与样本拟合良好。同样，结果支持BRIEF-2在不同性别间的测量不变性。指标分数的α系数值在0.71至0.91之间，各分量表的系数在0.66至0.88之间。这些发现支持了BRIEF-2分数的因子效度，表明它是评估父母和照料者报告的执行功能的一种合适工具。未来的研究必须继续考察BRIEF-2在不同人群和文化中的结构及不变性。
