Productive activity and the prevention of behavior problems.

This study used data from the National Institute of Child Health and Human Development Study of Early Child Care to examine relations between parenting, self-control, and externalizing behavior among 1st graders. Of special concern was the relation between opportunities for productive activity and behavior problems and whether the relation was mediated by self-control. Evidence in favor of the hypothesis was observed for both mother-reported and teacher-reported externalizing behavior even with substantial controls on the models examined. Self-control also mediated relations for maternal harshness and maternal sensitivity. Somewhat surprisingly, the direct effect of maternal sensitivity on mother-reported externalizing behaviors was positive.
