Correlation between IQ and Communication scores by IQ range. Groups consisted of youth with heavy prenatal alcohol exposure (AE) and nonexposed control (CON) subjects. Within the low IQ range (FSIQ < 85), the correlation between IQ and Communication was significant in both groups though this relationship was stronger in the CON group than the AE group. Within the high IQ range (FSIQ ≥ 85), the correlation between IQ and Communication was significant only in the CON group. IQ was measured with the Full Scale IQ standard score from the Wcchslcr Intelligence Scale for Children – Fourth Edition (WISC-IV) and communication was measured with the Vineland Adaptive Behavior Scales – Second Edition (VABS-II) Communication standard score.
