Trust, Participation, and Power: Community Perspectives from the Equity in Public Health Initiative.

Health disparities arise from unequal power relations shaping resource allocation, governance, and community agency. Community power is a key mechanism for addressing disparities. This study examines how visible, hidden, and invisible power operate within a U.S. county to inform inclusive governance. We conducted seven focus groups with Black and Hispanic residents (n = 68) and sixteen semi-structured interviews with elected officials, government staff, and advocacy leaders in Greenville County, South Carolina. Data were collected between March and December 2024. Transcripts were collaboratively coded in NVivo and analyzed using thematic analysis guided by Heller et al.'s Three Faces of Power framework. Visible power appeared through inequitable resource distribution, limited transparency, and barriers to civic participation. Hidden power functioned through faith based organizations, schools, nonprofits, and social media, connecting residents with decision makers. Invisible power reflected how socioeconomic status, race and ethnicity, immigration, and language shaped perceptions of agency and trust. Participants called for participatory structures that move beyond consultation toward shared authority and sustained engagement. Strengthening community power through structural reforms, inclusive governance practices, and targeted civic engagement may improve health outcomes and reduce disparities. Future research should examine scalable co-governance models.
