Linear regressions of temperamental shyness predicting children’s preoperative anxiety (CPMAS) at Time 1 (T1) and Time 2 (T2)

Predictor	Pre-operative Visit (T1)				Day of Surgery Visit (T2)
	Unstandardized Beta	S.E.	R2	ΔR2	Unstandardized Beta	S.E.	R2	ΔR2
Temperamental shyness	−10.78*	4.89	.12*	.09*	−12.31*	5.58	.13	.10

S.E. = standard error; N = 40;

^*p ≤ .05.

Note: Temperamental shyness remained a significant predictor after controlling for sex, age and previous hospitalization at T1 and T2
