Results from linear regression models with inhibitory control, impulsivity, novelty seeking, and demographic variables as predictors of overt or relational aggression (no interaction terms).

	Model 1 (outcome: relational aggression)	Model 2 (outcome: overt aggression)	Model 3 (outcome: relational aggression)	Model 4 (outcome: overt aggression)

SES composite	−0.035 (0.039)	−0.098* (0.040)	−0.036 (0.036)	−0.11* (0.038)

Note: CBQ = Children's Behavior Questionnaire; EATQ = Early Adolescent Questionnaire; sex was coded as 1 for females and 2 for males; pubertal status is based on a composite of mother and self-report of physical development (breast development, body hair growth, etc.); SES composite is a combination of standardized values for family income and mother's number of years of education; values in the cells are unstandardized partial regression coefficients, with standard errors in parentheses.
