Summary of hierarchical regression analyses for children’s birth status and children’s sustained selective attention performance predicting children’s problem behavior, as reported by mothers and teachers

	Variable	B	SE B	95% CI	β	p	sr 2
Source: Mother
Step 1	Birth status	3.58	0.88	[1.86, 5.31]	.18	<.001	.03
Step 2	Birth status	3.04	0.88	[1.29, 4.78]	.15	.001	.02
	Sustained selective attention	0.44	0.14	[0.17, 0.72]	.14	.002	.02
Source: Teacher
Step 1	Birth status	2.13	0.74	[0.68, 3.58]	.13	.004	.02
Step 2	Birth status	1.59	0.74	[0.13, 3.05]	.09	.033	.01

B indicates unstandardized B; β, standardized β; sr ², squared semipartial correlation. Adjusted R ² = 0.03 for Step 1 (p < .001); ∆R ² = 0.05 for Step 2 (p < .001) for both mother and teacher sources
