Pediatric primary care clinicians (PPCCs) are managing increasing mental health challenges in the children and adolescents they treat. Child and adolescent psychiatrists (CAPs) are increasingly involved in collaborative and integrated care (CIC) work that builds the knowledge and skills of PPCCs to manage mild to moderate mental health challenges for children and adolescents in primary care. CAPs who can establish good working relationships, communicate clearly and efficiently, and facilitate the care of this population will be successful in engaging our PPCC partners in CIC.
