Variables	Model I (with no interaction) Coefficient (P)	Model II (with interaction) Coefficient (P)
Age	1.02 (0.001)	1.76(<0.001)
Gender	−3.55(<0.001)	−3.42(<0.001)
Parental relationship	−0.07(0.017)	−0.22(0.548)
Interaction with age	/	−0.02(<0.001)
Hyperactivity - Impulsivity	1.95(<0.001)	0.12(0.286)
Interaction with parental relationship	/	0.04(<0.001)
Model fit, F(df), p value	Multiple R = 0.41, R2 = 0.172, Adjusted R2 = 0.169, F(4) = 53.61, p<0.001	Multiple R = 0.42 R2 = 0.174, Adjusted R2 = 0.171 F(4) = 54.64, p<0.001

Note: here age is a continuous variable. However, age variable in the interaction figure is segment into two.
