ABSTRACT

This cross-sectional study examined whether the temperament dimensions of negative emotionality, positive emotionality, and impulsivity moderated the relation between interparental conflict and children’s internalizing and externalizing problems. The sample consisted of 355 divorced mothers and their children (9-12 years old) who participated in a randomized controlled trial of a preventive parenting intervention for divorcing families. Children provided reports of their experiences of interparental conflict and internalizing and externalizing problems; mothers provided reports of children’s temperament and internalizing and externalizing problems. The relations were examined separately for child report and mother report of outcomes using multiple regression analyses. Results found no support for the interactive effect of interparental conflict and temperament dimensions on children’s internalizing or externalizing problems. Consistent with an additive model of their effects, interparental conflict and temperament dimensions were directly and independently related to the outcomes. There was a significant, positive effect of interparental conflict and negative emotionality on children’s internalizing and externalizing problems. Positive emotionality was significantly, negatively related to internalizing and externalizing problems. Impulsivity was significantly, positively related to externalizing problems only. The patterns of results varied somewhat across mother and child report of interparental conflict on externalizing problems and positive emotionality on internalizing problems. The results of this study are consistent with the previous research on the significant main effects of interparental conflict and temperament dimensions on children’s internalizing and externalizing problems. These findings suggest that children’s environment and intrapersonal characteristics, represented by children’s experiences of interparental conflict and temperament, both uniquely contribute to children’s post-divorce internalizing and externalizing problems.
