Table 1.

Mean scores (M) and standard deviations (SD) on Verbal IQ (VIQ), Performance IQ (PIQ) and Full Scale IQ (FSIQ) in a group of children (n= 80) divided into three subgroups: children in the traumatized parents group without PTSD-related symptoms (n = 9), children in the traumatized parents group with PTSD-related symptoms (n = 31), and children in the non-traumatized parents (n = 40). F-ratio for one-way ANOVAs (df2.78) and significance (Tukey 1%) for subgroup comparisons

IQ	Traumatized Non-PTSD-related symptoms A		Traumatized PTSD-related symptoms B		Non-Traumatized C				Post-hoc test p < 0.01
	M	SD	M	SD	M	SD	F	p
VIQ	91.7	14.3	86.7	11.1	104.2	12.4	18.8	<.001	C > A, B
PIQ	83.4	16.5	86.2	13.9	100.7	14.8	10.7	<.001	C > A, B
FSIQ	86.4	15.9	86.5	12.1	102.5	13.2	18.3	<.001	C > A, B

Note: A = Children without PTSD-related symptoms in the traumatized parents group;

B = Children with PTSD-related symptoms in the traumatized parents group;

C = Children in the non-traumatized parents group.
