Background: As many as 20 % of children have diagnosable mental health conditions and nearly all of them receive pediatric primary health care. However, most children with serious mental health concerns do not receive mental health services. This study tested hypotheses that pediatric primary care providers (PPCPs) in relationships with mental health providers would differ in their care of patients with mental health concerns when compared to PPCPs not in such relationships. Objective: To explore differences between PPCPs who have relationships with mental health care providers and those who do not with regard to their care of children with mental health concerns. Methods: Seventy-two PPCPs completed a mailed survey addressing topics such as comfort levels diagnosing and managing patients with behavioral health disorders, perceived barriers to care, activity related to prescribing psychotropic medications, and availability of consultation with mental health specialists. More than one-third (19 providers) of providers reported no specialized training in behavioral pediatrics and nearly 45% (32 providers) indicated having a relationship or partnership with a mental health specialist. Results: Those providers who reported relationships indicated greater availability of consultation and communication with psychiatric providers as well as telephone consultation with non-psychiatric mental health providers. All providers were more comfortable assessing as opposed to treating children with disorders, with the exception of attention disorders, which providers were comfortable with both treating and assessing. For all conditions, there was no main effect for partnership. Conclusion: While partnerships may be associated with greater availability of consultation and communication, for this sample of PPCPs there was no evidence of advantage with respect to diagnosis and management. The paper concludes with a discussion of study limitations, the need for further research, and suggestions for practice.
