OBJECTIVES/GOALS: This theory analysis aims to evaluate a middle-range framework, the HSDF1, in the context of sexual assault stigma incorporating the myriad levels within within culture and society through which stigma can occur and be reinforced. METHODS/STUDY POPULATION: Databases: PubMed, CINAHL, EMBASE, Google Scholar, Organization websites, Citation searchesn = 32Mark Risjord’s “Middle-Range Theories as Models: New Criterion for Analysis and Evaluation” (2019) RESULTS/ANTICIPATED RESULTS: The innovative approach of the HSDF guides understanding of sexual assault stigma in a holistic way, incorporating individual and institutional stratum of the phenomenon. Understanding through integration of this theoretical framework alongside current knowledge may more succinctly inform trauma-informed care for survivors, policy, and cultural awareness for nurses, healthcare providers, police, social workers, and myriad others with whom survivors interact. DISCUSSION/SIGNIFICANCE: Applying the HSDF framework to sexual assault stigma could help break down barriers and raise survivors out of stigmatization, affecting population health through reduced negative health sequelae experienced by survivors.
