Abstract: Background: Opioid overdose deaths pose a serious public health concern in the United States, with disproportionately higher rates of increase among Black Americans despite expanded naloxone access. Improving community knowledge and confidence in naloxone use may be critical to reducing these disparities. Objective: This study assessed individual- and community-level factors associated with knowledge and perceived competency in managing opioid overdose and administering naloxone among urban Indiana residents. Methods: A probability-based household survey was conducted between March to May 2023 across eight Indiana zip code areas (N = 772) with high (> 40%) proportions of Black residents. Multilevel modeling was used to examine individual- and community-level factors associated with opioid overdose knowledge and perceived competency, using adapted items from the Opioid Overdose Knowledge Scale (OOKS) and Opioid Overdose Attitudes Scale (OOAS). Results: Race, sex, household income, education, time lived in the community, and history of opioid overdose significantly predicted knowledge scores. White participants scored higher (mean 6.65) than Black participants (5.70) (p
