A Comparison of Three Executive Function Batteries in a Preschool-Aged Sample

There is great interest in the development of executive function (EF) in the preschool period. Accordingly, multiple performance-based measures of EF have been developed for this age group, yet little is known about how they compare to one another. This study used a large and diverse sample of 3-to-5-year-old children (N = 846), who completed subtests of the National Institutes of Health’s Toolbox Cognition Battery (NTCB), the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV), and the EF Touch battery. Scores across the three batteries were compared and associations with age, income, and race/ethnicity were examined. Results revealed that (1) the three tasks were moderately correlated (r = 0.44–0.51, all p < 0.001), but children had higher mean accuracy scores on EF Touch than on the NTCB or the WPPSI-IV. (2) Mean accuracy scores on all batteries were linearly associated with child age (all F > 32.68, all p < 0.0001). (3) Comparisons by income and race/ethnicity showed lower accuracy for low-income children on the WPPSI-IV and lower accuracy for White children on the NTCB. Across all batteries, there was consistently lower accuracy for Hispanic children. In conclusion, the three batteries we examined performed similarly across several metrics. EF Touch may be more appropriate for younger children, while the NTCB performed well with older children.
