The Institute for Implementation Science Scholars (IS-2) is a dissemination and implementation (D&I) science training and mentoring program. A key component of IS-2 is collaborating and networking. To build knowledge on effective networking and mentoring, this study sought to 1) conduct a social network analysis to determine whether underrepresented scholars have equivalent levels of connection and 2) gain insights into the differences in networking among racial/ethnic subgroups of scholars.

Social network survey data were used to select participants based on number of collaborative connections (highest, lowest) and racial/ ethnic category (underrepresented, not underrepresented). Interviews were recorded, transcribed, and coded using an iterative process.

The sample consisted of eight highly networked scholars, eight less networked scholars, seven from underrepresented racial and ethnic groups, and nine from not underrepresented groups. Qualitative data showed a lack of connection, reluctance to network, and systematic issues including institutional biases as possible drivers of group differences. In addition, scholars provided suggestions on how to overcome barriers to networking and provided insights into how IS-2 has impacted their D&I research and knowledge.

Underrepresented scholars have fewer network contacts than not underrepresented scholars in the IS-2 training program. It is imperative for leadership to be intentional with mentorship pairing, especially for underrepresented scholars. Future research might include interviews with program leaders to understand how network pairings are built to improve the mentorship experience.

Members of many racial and ethnic population subgroups are underrepresented in clinical trials and research. We present perspectives on barriers and facilitators to study participation gathered from Hispanic participants in a population-based genetic screening study.

Seven focus groups (five in English and two in Spanish) were conducted with self-identified Hispanic participants of the Healthy Oregon Project (HOP), a large population-based cohort of adults residing in Oregon. HOP study participants complete surveys about cancer and chronic disease risks with the option to donate a saliva sample for no-cost genetic risk screening for inherited disorders. HOP invited Hispanic participants via email to join a focus group about their experiences. Focus groups, generally lasting 60–90 minutes, occurred in person and virtually. Notes were coded and content-analyzed.

49 Hispanic adults participated in the focus groups (37 women; 9 men; 3 non-binary people). Identified facilitators for HOP study participation were trust in the academic medical center leading the study, having a family member who was impacted by cancer, and receiving free genetic screening. Identified barriers were difficulty completing the family history survey, lack of understanding or familiarity with research, immigration status, and navigating technology challenges. Recommendations to improve recruitment of Hispanic populations included promoting the study at community events, clinics, or schools, simplifying the consenting process and providing patient-focused videos to demonstrate study tasks, providing real-time sample tracking, and offering monetary incentives.

Our findings can inform strategies for bolstering recruitment of Hispanic adults in biomedical research studies.
