All scores have been transformed to deviation quotient scaling with a normative M = 100 and SD = 15 in order to facilitate comparisons across instruments. Statistical results consist of the omnibus F test for that row, followed by Bonferroni-adjusted post-hoc comparisons in cases where more than two scores are compared or a notation of the direction of the difference when only two scores are compared. For the statistical results: V = VABS-II, B = BASC-2 PRS, and A = ABAS-II.
