Summary of hierarchical regression analyses for variables predicting parent-reported ODD symptoms

Predictors	Parent-reported HI		Teacher-reported HI		IED
Predictors	β	R² (f²)	β	R² (f²)	β	R² (f²)
Step 1		0.08 (0.09)		0.08 (0.09)		0.08 (0.09)
Sex	−0.15		−0.15		−0.15
Age	0.18		0.18		0.18
IQ	−0.08		−0.08		−0.08
Income-to-needs ratio	0.07		0.07		0.07
Family structure	−0.05		−0.05		−0.05
Step 2		0.51^*** (1.04)		0.24^* (0.32)		0.09 (0.10)
Sex	−0.02		−0.04		−0.16
Age	0.02		0.21		0.23
IQ	−0.04		−0.12		−0.09
Income-to-needs ratio	0.02		0.03		0.08
Family structure	0.00		−0.06		−0.07

Family routine	−0.07		0.08		0.13
HI × routine^a	−0.12		0.02		−0.10

HI was indexed by parent-reported HI symptoms, teacher-reported HI symptoms, and child IED performance (see column headings)

Sex was coded as 0 (male) or 1 (female), family structure was coded as 0 (not 2-parent household) or 1 (2-parent household), HI = hyperactivity/impulsivity, IED = intra/extra dimensional set shift, effect size = f²
