180 Background: Rural populations and racial minorities are often underrepresented in cancer clinical trials. The low representation is determined by multilevel factors, including lack of geographic access to facilities in rural locations and mistrust in the medical and scientific community. Presented here are partial results of an educational intervention to improve clinical trials-related knowledge among rural residents and racial minorities. Methods: The Center to Reduce Cancer Health Disparities (CRCHD) from the National Cancer Institute (NCI) developed the study materials, that were available in English or Spanish, to be utilized according to participants' preferences. The University of Wisconsin Carbone Cancer Center implemented this intervention in northern Wisconsin, which consisted of a baseline questionnaire, a recorded educational intervention, and a post-educational questionnaire. The chosen community is largely rural and Native. The questionnaires consisted of 11-knowledge- and 6-intention-related questions. After being screened by the rural Community Health Educator (CHE), subjects self-administered the intervention online or received the intervention from the CHE during tribal or other educational group events in rural communities. Results: Between January and May 2024, 62 participants started the intervention. Participants’ mean age was 45.1 (±15.36) years, 64.5% (40/62) were female, and 53.2% (33/62) self-identified as American Indian/ Alaska Native. All resided in rural community, defined as Rural-Urban Continuum Codes 7 or 8. Three participants did not respond to the post-educational questionnaire, and one skipped its intentions section. Although the two questions about informed consent presented the highest percent of correct answers post-intervention, the median total knowledge score pre and post-intervention remained the same (p>0.05). Post-intervention, participants more often agreed it is important for minority groups to participate in clinical trials, reported being likely to search for a clinical trial they might be eligible for, join a clinical trial, and talk to family/friends about joining a clinical trial (p<0.05). Conclusions: The CHE successfully engaged rural community members to participate in the intervention. In addition, the intervention facilitated building trust and partnerships for future cancer-related community driven work.
