Using the Delphi Process in the Development of the Partnering to Build Understanding of Genomics Responsibly Community Health Worker (PREFER CHW) Research Education Program.

CONTEXT: Community Health Workers (CHWs) are increasingly involved in genomics-related communication and research engagement, yet few genomics training programs are tailored to their roles, learning needs, or community contexts.

OBJECTIVE

To refine and build consensus on the content, structure, and applicability of the PaRtnEring to build understanding oF gEnomics Responsibly (PREFER) CHW Genomics Research Education Program using a multiround Delphi process.

DESIGN

A 3-round Delphi study incorporating quantitative ratings and qualitative feedback to evaluate and revise curriculum modules and activities.

SETTING

Five CHW partner training sites across the Southeastern United States.

PARTICIPANTS

Twenty-four individuals, including CHWs, CHW trainers, and genetics content experts. CHWs and CHW trainers comprised 83% of the panel.

INTERVENTION: An iterative refinement of a 10-module genomics education curriculum covering topics such as Genetics 101, Family History, Genetic Counseling and Testing, CHW Roles, Genetics Research, Ethical/Legal/Social Issues, and Communicating About Genomics.

MAIN OUTCOME MEASURES: Clarity of learning objectives, use of adult learning theory, anticipated knowledge gain, and appropriateness of module-specific workbook activities, assessed using the Kirkpatrick Model and predefined consensus threshold of ≥75% agreement.

RESULTS

In Round 1, Genetics 101 and CHW Roles scored below the 75% consensus threshold. Round 2 focus groups identified needs for simplified scientific content, strengthened integration of CHW roles, and expanded real-world examples. In Round 3, 18 full assessments showed improved agreement across modules, although gaps remained in adult learning integration for selected modules. The final curriculum achieved consensus on clarity and anticipated knowledge gain across all modules.

CONCLUSIONS

The Delphi process effectively refined the PREFER curriculum and ensured alignment with CHW needs. CHWs played a central role throughout development, directly shaping content, structure, and cultural relevance. The resulting curriculum offers a feasible, community-aligned approach to building CHW capacity in genomics communication and research engagement.
