Theoretical and empirical evidence suggests that two of the most common childhood syndromes, disruptive behaviors and depression, have similar developmental antecedents and may respond to similar interventions. Recent evidence suggests that parenting interventions that target more nurturing and less harsh parenting risk factors lead to reduced internalizing symptoms in children (Webster-Stratton & Herman, 2008) in addition to the well-established effects on child conduct problems. For instance, Webster-Stratton and Herman (2008) found that children whose parents participated in the IY Parent Training (PT) program had reduced depressive symptoms at post-treatment compared to children in a wait-list control condition. Effects were mediated by changes in parenting effectiveness.
