Significant estimates are in boldface. T1 first assessment; T2 9-month follow-up; T3 18-month follow-up; Flex*Neg = interaction term between maternal negative affect and affective dyadic flexibility. Paths a. b. and c’ refer to the commonly used denotations for the different paths between the predictor, mediator and outcome in mediation models. R 2 = 0.33 for hyperactive/impulsive behavior. R 2 = 0.36 for aggressive behavior
