NOTE. Intercept is mean score for the overall group at the End of Therapy. Slope is estimated change in standardized score points from End of Therapy to 2 Years Post. Expected normative mean is 100 for estimated IQ, FFD, PSI, and WIAT; 50 for Connors Parent Rating Scales, CPT, and CVLT-List A Total; 0.0 for CVLT Learning Slope, Short Delay and Long Delay Free Recall.

Abbreviations: CPT, Continuous Performance Test; CVLT, California Verbal Learning Test; FFD, Freedom from Distractibility Index; PSI, Processing Speed Index; WIAT, Wechsler Individual Achievement Test.
