The objective of this study was to assess feasibility, utilization, perceived value, and targeted behavioral health (BH) treatment self-efficacy associated with a collaborative child and adolescent psychiatry (CAP) consultation and BH education program for pediatric primary care practitioners (PCPs). Eighty-one PCPs from 41 member practices of a statewide pediatric practice association affiliated with an academic medical center participated in a program comprising on-demand telephonic CAP consultation supported by an extensive BH learning community. Findings after 2 years of implementation suggest that the program was feasible for large-scale implementation, was highly utilized and valued by PCPs, and was attributed by PCPs with enhancing their BH treatment self-efficacy and the quality of their BH care. After participation in the program, nearly all PCPs believed that mild to moderate presentations of common BH problems can be effectively managed in the primary care setting, and PCP consultation utilization was congruent with that belief.
