Synergistic interaction of child manageability problems and parent-discipline tactics in predicting future growth in externalizing behavior for boys.

Manageability problems during early childhood for boys were hypothesized to disrupt parental discipline practices. In turn, disrupted parental discipline practices were hypothesized to interact with manageability problems during late childhood to predict change in antisocial behavior during the transition from elementary to middle school. Results indicated that maternal retrospective perceptions of unmanageability predicted observed maternal discipline practices, even when maternal antisocial behavior and depressed mood and the disruptive and antisocial behavior of the boy were statistically controlled. Graphical analyses and latent class growth models indicated that level of temper tantrums interacted with maternal discipline in predicting change in teacher ratings of antisocial behavior. The nature of the interaction indicated that maternal discipline was a risk factor for growth in antisocial behavior only for boys with high levels of tantrums.
