FIQ = full intelligence quotient, VIQ = verbal intelligence quotient, PIQ = performance intelligence quotient, VCI = verbal comprehension index, POI = perceptual organization index, FDI = freedom from distractibility index, PSI = processing speed index.
Our results revealed a statistically significant difference between children affected by TTH and the control group with regard to the TIQ score (full intelligence quotient scale); this difference was even more significant between children affected by MoA and the control group (Table 2).
Pro-rated full intelligence quotient (IQ) scores were derived from four subtests of the Wechsler Intelligence Scale for Children (WISC-III NL) [ 56]: picture completion, block design, similarities and vocabulary [ 45].
Lederman et al. (2008) assessed Psychomotor Development Index (PDI) and Verbal and Full Intelligence Quotient Scores (VFIQS) (at 36 months of age for PDI and 48 months for VFIQS) as a function of prenatal mercury exposure (corrected for maternal fish intake during pregnancy) resulting from potential exposure after the World Trade Center (WTC) disaster.
Based on all four subtests one can derive the Full Scale Intelligence Quotient (FSIQ).
All participants were administered the vocabulary and matrix reasoning subtests of the Wechsler abbreviated scale of intelligence (WASI; [59]), from which a full scale intelligence quotient (FSIQ) was calculated.
Full scale intelligence quotient (IQ) is measured using the Coloured Progressive Matrices (CPM) [ 47].
GHDT scores had a high interrater reliability coefficient (0.96) and correlated significantly with Full Scale intellectual quotient (IQ) on the WISC (r = 0.64, p < 0.05) (Gayton et al., 1974).
At the last testing mean full scale intelligence quotient (FSIQ), verbal IQ (VIQ) and performance IQ (PIQ) were 89.1 (standard deviation SD 14.6), 94.0 (SD 12.4), and 86.2 (SD 16.1).
Compared to children with no brain abnormalities (as confirmed by MRI examination), children with a history of CVA have significantly lower full scale intelligence quotient (IQ), verbal IQ, performance IQ and math achievement [ 10].
