Predominantly Spanish-speaking Latinx individuals are underrepresented in research, and one primary barrier is the lack of infrastructure to effectively engage, among them, adequate cultural and linguistic adaptation of research measures.Capitalizing on existing recommendations for appropriate and ethical engagement of Latinx individuals in research, we present a comprehensive approach to cultural and linguistic adaptation, and describe the application of this approach in the context of an ongoing longitudinal, observational, community-engaged study that follows a cohort of young adult Latinx immigrants (ages 18-44) in the Southeastern region of the United States who were predominantly Spanish-speakers (N = 391).We describe barriers that researchers may face in their pursuit of cultural and linguistic adaptation and offset these challenges with tangible solutions. We discuss lessons learned through our application to a research study. This approach holds promise for reducing barriers to participation in research and health disparities in predominantly Spanish-speaking Latinx individuals, who represent a population that is growing in size in the United States yet is still underrepresented as research participants and in the research workforce.
