Purpose: To investigate the characteristics of studies that included underrepresented speech-language pathologists (SLPs) as research participants, to better understand the knowledge that was generated, the research processes that were used, and the extent to which they could enable empowerment of participants.Method: A scoping review was conducted according to the principles of the transformative research paradigm, which promotes the involvement of marginalized groups in ways that amplify their voices, value their knowledge, and address power inequities. Consultation and co-production with minority SLPs were facilitated. The search strategy was run in six databases, and the transformative checklist was used to analyse the studies. Results: 20 studies were included. Bilingual and male SLPs were among the most commonly included underrepresented SLPs. Most studies were conducted in the USA (n=16), and used quantitative survey methods to investigate SLP service delivery with disaggregation of data by SLPs with different attributes. Findings of the included studies provided valuable insights into the unique experiences and practices of underrepresented SLPs, and yielded practical solutions to foster inclusion and diversity in the profession. Most studies demonstrated a transformative potential, but the authors’ plans to achieve change were often unclear, and the active engagement of underrepresented SLP participants in the research cycle was demonstrated in only five studies.Conclusion: This review calls for a shift in how and why research is conducted when including underrepresented SLP participants. Through the lens of the transformative research paradigm, we can rethink the broader aim of research and the role of researchers and participants. Using research as a platform to give visibility, voice and agency to the minority members of our community can shape the evidence-base and inform tomorrow’s SLP practices, hence becoming an empowering mechanism to stimulate change and equity in the profession.
