Most children and adolescents with behavioral and mental health concerns first present to their pediatricians. Although pediatricians are fully aware of the importance of addressing behavioral and mental health concerns, they often find it difficult to deliver such care effectively and efficiently in a typical practice setting.

In pediatric primary care practice, integrated behavioral health (IBH) has been shown to be a cost-effective way to deliver high-quality care. This article describes basic definitions and contexts of integrated pediatric behavioral health.
