From Mistrust to Medicine: Rebuilding Inclusive Participation in Clinical Research

On a rainy Tuesday evening, Ms. Johnson sat in the clinic parking lot, staring at the flyer for a “promising new study” her doctor had handed her that afternoon. She had just lost a cousin to a condition this trial claimed to target, yet a knot of doubt kept her from walking back inside, torn between hope for better care and fear of being “experimented on” without clear answers.

This story reflects a broader reality: communities most affected by chronic disease- often people of color, immigrants, rural residents, and low-income families- are routinely asked to trust a research system that has not always earned their trust, even as the results of that research shape which treatments work best, for whom, and under what conditions. When these communities are missing from clinical trials, new therapies may look effective on paper but fail to serve those most at risk in real-world practice.​

Inclusive Representation in Clinical Research

Clinical trials cannot advance equitable care if the communities most burdened by disease remain absent, including racial and ethnic minorities, women, rural residents, and low‑income populations. When community health workers, patient navigators, and trusted neighborhood institutions step in to bridge gaps in trust, access, and communication, participation becomes more feasible and lifesaving innovations become accessible to a broader range of people.​

Partnering with Communities and Trusted Institutions

One of the most effective strategies to improve enrollment of underrepresented populations in clinical trials is the integration of community health workers (CHWs), patient navigators, and trusted local institutions. These partners, who often share similar socioeconomic, linguistic, or cultural backgrounds with the populations they serve, help dispel myths, clarify misconceptions, and promote culturally and linguistically appropriate dialogue about research.​

Local partnerships with churches, barber shops, cultural centers, and civic groups are effective for building rapport and increasing awareness about clinical trials across diverse communities. When researchers collaborate with these entities to co‑host informational sessions or health screenings and maintain ongoing presence rather than one‑time events, they gain credibility and foster mutual respect, often facilitated by municipal staff and local health departments.​

Tailoring Communication and Addressing Health Literacy

Low health literacy, limited awareness, and culturally irrelevant materials are major barriers to trial participation among many underrepresented groups, including Black, Latino, Asian, Pacific Islander, and rural communities. Recruitment materials, informed consent documents, and educational content should use plain language, reflect the lived experiences and concerns of specific populations, and be reviewed by community advisory boards or cultural consultants.​

Multimedia tools such as videos, podcasts, and interactive apps can make complex trial information accessible when they feature diverse voices and faces, testimonials from past participants, and clear explanations of procedures and risks. Providing translation services, bilingual or multilingual materials, and support for limited English proficiency is crucial in areas with linguistically diverse populations.​

Reducing Logistical Barriers and Increasing Flexibility

Transportation challenges, caregiving responsibilities, and rigid schedules are well‑docu
