title: Validation of the BRIEF-P in a sample of Canadian preschool children.
abstract: The Behavior Rating Inventory for Executive Function-Preschool (BRIEF-P) is an instrument designed to assess preschoolers' executive function (EF) in the context of where the behavior occurs. The present study examined the psychometric properties and measurement structure of the BRIEF-P using parents' and teachers' reports on 625 typically developing children aged 25 to 74 months. Results indicated that the BRIEF-P scales had good internal consistency and convergent validity in this sample of children. However, the measurement models examined exhibited poor fit statistics and showed that the EF construct was not unidimensional but rather multidimensional with interrelated subconstructs. Further analyses showed that three of the clinical scales (Emotional Control, Plan/Organize, and Working Memory) were unidimensional and invariant across informant. The other two clinical scales (Inhibit and Shift) were multidimensional and differed by informant. Results support a multidimensional construct of EF and, accordingly, different measurement models are proposed by informant.
