OBJECTIVES/GOALS: - Illuminate processes and findings of a translational science case study of impactful research with incarcerated pregnant women and mothers; - Improve our understanding of the translational mechanisms by sharing translational challenges, facilitators, an METHODS/STUDY POPULATION: Utilized the following evaluation methods and tools: - The Retrospective Translational Science Case Study protocol to examine translational path from innovation to policy and practice, barriers and facilitators for that translational movement. - Translational Science Benefits Model (TSBM) Checklist for translational/research impact analysis Triangulated diverse data sources: - Primary data: semi-structured interviews with research partners - Secondary data: researchers’ grant applications, reports, and publications; public stories/news related to their research; scientific publications; organizational/policy documents; and over 50 interviews with 30 stakeholders featured in published sources. RESULTS/ANTICIPATED RESULTS: The research contributed to community and public health, policy/legislative, clinical/medical, and economic benefits, social/institutional change, health equity advocacy, catalyzing research (consequent research studies) and public awareness. Translational research challenges: cultural differences between research and prison system; politics of translating research to policy change; issues of capacity, power, privilege, and opportunity when doing community-engaged research; and science vs. social justice criticism. Facilitators of translation: CTSA support; stakeholder engagement; authentic collaboration; researchers as translation catalysts; and engagement in legislative activities. DISCUSSION/SIGNIFICANCE: The evaluation case study provides useful knowledge about translational impact, challenges, and facilitators of community-based research that moved along the translational continuum and contributed to transformational, systemic changes on the legal, clinical, organizational, and interpersonal levels.
