PROJECT SUMMARY Over 268,000 children entered foster care in the United States during fiscal year 2019 despite the existence of evidence-based programs (EBPs) that can successfully prevent child maltreatment. Evidence-informed decision-making (EIDM) can lead to the adoption of EBPs that are likely to be successfully implemented and result in the intended impacts. Despite the existence of EBPs to prevent child maltreatment, EBPs are underutilized in child welfare. Proposed study activities in this career development award respond to NIMH Objective 4.2.c by developing, refining, and piloting an implementation strategy to increase EIDM when decision makers are adopting EBPs to improve mental health and child welfare services. Activities leverage an unprecedented federal policy opportunity to prevent child maltreatment and test implementation decision support strategies in the real world: The Family First Prevention Services Act (FFPSA). FFPSA aims to prevent child maltreatment and foster care entries by providing federal funding to states for implementing EBPs that support child and parent mental health, reduce parental substance misuse, and improve parenting skills. This project engages decision makers from four states implementing FFPSA to extend the candidate’s prior work developing an innovative EIDM tool to support EBP adoption: Optimizing Responses through Collaborative Assessments (ORCA). ORCA is based in multi-criteria decision analysis, which provides a structured approach to reach quality, evidence-informed group decisions. Given that group decisions with tools such as ORCA benefit from facilitation, this study will develop and test two facilitation modalities to accompany ORCA: automated (ORCA-A) and live (ORCA-L). In addition, a web-based platform to host the ORCA tool and the ORCA-A facilitation strategy will be developed with decision makers’ input (Aim 1). The impact of ORCA-A and ORCA-L on quality of decision experiences, processes, and outcomes then will be tested (Aim 2). Implementation process quality for each EBP adopted with ORCA-A and ORCA-L will be monitored (Aim 3). To enhance her strong foundation in the implementation, decision, and systems sciences, the candidate, Dr. Gracelyn Cruden, will leverage these research activities and training activities to expand her skillset to include: leading implementation studies in service systems, employing a continuum of methods for engaging community members, leveraging interdisciplinary approaches for eliciting members’ preferences, conducting advanced simulation model testing, and using advanced statistics for multilevel, longitudinal studies. Cruden will be mentored by an outstanding team led by Primary Mentor Dr. Lisa Saldana, who is accompanied by Mentors Dr. Jason Chapman, Dr. Lindsey Zimmerman, Dr. R. Christopher Sheldrick, Dr. Jonathan Purtle, and Consultants Dr. David Vanness, and Ms. Clare Anderson. Upon completion of these activities, Cruden will be equipped to lead an interd...
