Abstract:
Executive function (EF) encompasses several neurocognitive processes that are important in self-regulation of behavior and the attainment of social and cognitive competencies. While much progress has been made in developing valid measures for adult and adolescent EF, there is a dearth of valid measures for preschool children. Given the steep trajectory of neuropsychological development among this age group and the importance of EF, a valid measure for clinical assessment and research is needed that can capture EF in the everyday context of early childhood. The Behavior Rating Inventory of Executive Function Preschool Version (BRIEF-P) measures parent and teacher observations of children’s everyday self-regulatory behaviors. The BRIEF-P has been validated in a range of normative and non-normative samples, but further validation is needed across cultures. This study aimed to evaluate the cross-cultural validity and reliability of the BRIEF-P when used by New Zealand Māori (n = 131) and European (n = 193) parents of children born with risk factors of neonatal hypoglycemia. Parents of children who participated in the prospective, longitudinal Children with Hypoglycemia and their Later Development (CHYLD) study completed the BRIEF-P when the child was 2 years ±4 weeks and 4.5 years ±8 weeks old. Results showed that the BRIEF-P is a highly reliable and valid instrument. Comparisons between Māori and New Zealand European samples revealed biases, which could be a source of further work to improve the construct validity of this measure, such as the development of norms and item validation for non-European and non-Western samples.
