Note: The normative population for the BRIEF has a mean T score of 50 and a standard deviation of 10.

Higher scores signify lower function. The Hochberg adjustment was used to control for multiple comparisons.

Effect sizes designated as small (.20), medium (.50), and large (.80).

NS= not significant.
