The majority of children exposed to early adversity and trauma do not have access to sustainably delivered evidence-based mental health programs (EBPs), despite the growing prevalence of large-scale multiple-EBP implementation efforts aimed at increasing access to these services. The objective of this proposal is to develop and test a package of implementation strategies designed to promote the sustained delivery of child trauma EBPs by reducing provider turnover through targeting the associated mechanisms of provider burnout and organizational psychological safety climate. Findings will have a significant public health impact by informing efforts to increase the sustained availability of child trauma EBPs, thereby improving outcomes for children exposed to trauma.
