The barriers to creating systems and individual change to support effective preventive interventions are well documented across a variety of settings, including mental health treatment gaps in community practice settings and in schools (Cook et al., 2019;Fagan et al., 2019;Owens et al., 2014;Proctor et al., 2009). These implementation challenges occur counter to the ever-growing research base indicating the efficacy of preventive interventions (Catalano et al., 2012;Gottfredson et al., 2015; National Research Council & Institute of Medicine, 2009) as well the growing prevalence of many public health concerns in the last decade (Fagan et al., 2019). Implementation of evidence-based interventions (EBIs), including practices, programs, and policies, within complex systems requires an ecological approach that addresses barriers and facilitators at multiple levels including a top-down (e.g., policy, funding) and bottom-up (e.g., personlevel) approach (Fagan et al., 2019). Resistance and lacking fidelity to EBIs occurs at the person level and is an important area to consider in optimizing EBI implementation. Not surprisingly, readiness, awareness of and attitudes supportive of EBIs, capacity to implement, and leadership have all been identified as key factors impacting the widespread, effective use of EBIs across public systems (i.e., behavioral health, child welfare, education, juvenile justice, and public health; Fagan et al., 2019). Despite emerging type 2 translational research that contributes to the field's understanding of how to promote the adoption, implementation, and sustainment of EBIs in complex, real-world settings, there is still a need for * Elise T.
