Dimensional structure and measurement invariance of the BRIEF-2 across gender in a socially vulnerable sample of primary school-aged children

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.
