BRANCH (Building Resilience And Nurturing CHildren) is a brief trauma-informed, extended screening and assessment intervention developed for integrated behavioral health clinicians (BHCs) who practice in primary care pediatric settings. The impetus for developing BRANCH has come from the experiences of TEAM UP for Children, and the need to build the capacity of TEAM UP community health centers (CHCs) to provide early childhood mental health services in the primary care setting. BRANCH may be used to elicit and explore parent concerns about child behavior or development, to screen for traumatic stress, to provide developmental guidance and information, and to engage families in forming a plan for stepped-up care. This report provides a summary of BRANCH’s development and implementation during the period of September 2017-May 2020.
