Psychometric characteristics of the BRIEF scale for the assessment of executive functions in Spanish clinical population.

Background: The Behavior Rating Inventory of Executive Functions (BRIEF) scale, completed by families, is widely known in the assessment of executive functions in children and adolescents. However, its application is limited to English-speaking population.

Method: This study analyzes the preliminary results from its application in a Spanish clinical sample, comprising 125 participants aged 5-18 years. Internal structure and reliability of the translated scale were analyzed, as well as its relationship with other behavioral measures through the analysis of their correlations with the Assessment of Attention Deficit Hyperactivity Disorder Scale (EDAH). The results were compared with those from the original validation study.

Results: The data revealed the presence of the same internal structure, as well as acceptable internal consistency and significant correlations with the Attention Deficit and Hyperactivity components of the EDAH scale.

Conclusions: This study provides preliminary evidence of the utility of the BRIEF scale in cultural contexts different from the original, particularly in Spanish clinical population.
