This article focuses on the cross-discipline training competencies needed for preparing behavioral health providers to implement integrated primary care services. After a review of current competencies in the disciplines of child and adolescent psychiatry, psychology, and social work, cross-cutting competencies for integrated training purposes are identified. These competencies are comprehensive and broad and can be modified for use in varied settings and training programs. An existing and successful integrated care training model, currently implemented at Children’s Hospital of Philadelphia, is described. This model and the training competencies are discussed in the context of recommendations for future work and training.
