Vineland-II Adaptive Behavior Scale Scores (Parent Informant)

Domain	TBI (n = 16)		TDC (n = 12)		t(26)	p	d
	M	SD	M	SD
Socialization	96.0	11.2	101.9	6.7	1.62	0.117	0.64
Communication	96.9	16.3	108.2	12.5	1.99	0.057	0.78
Daily Living Skills	100.9	13.7	105.3	10.3	0.91	0.370	0.36
Adaptive Behavior Composite	98.1	14.5	105.8	8.0	1.67	0.107	0.66

All scores are reported as standard scores with a mean of 100 and a standard deviation of 15; Cohen's d ≥ |0.20|, |0.50|, and |0.80| indicate a small, medium, and large effect size, respectively.²⁹

TBI, traumatic brain injury; TDC, typically-developing children; M, mean; SD, standard deviation.
