The present article provides an overview of the best-developed interventions for child and adolescent internalizing disorders characterized by anxiety and depression. The review emphasizes interventions that fall into established efficacy categories, but also addresses briefly several other promising treatment procedures. Research on the treatment of child and adolescent depression has not yielded interventions with clearly established efficacy, although there are a number of treatment approaches that may be characterized as possibly efficacious. The treatment of child and adolescent anxiety disorders, on the other hand, includes a number of interventions with good empirical support. While the field is clearly advancing, there remain important deficits and limitations with regard to the evidence base for interventions addressing child internalizing disorders.
