Using longitudinal qualitative research to understand the experiences of minoritized people.

This paper demonstrates how Longitudinal Qualitative Research (LQR) is an innovative method to understand the lived experiences of members of minoritized groups when temporality is a structuring element of their experiences. Most qualitative research in psychology is cross-sectional, which limits our understanding of individuals whose experiences are context-dependent and linked to the temporal norms of specific social environments. LQR is unique for allowing researchers to compare change and stability over time and reveal how social challenges and barriers impact perspective shifts and long-term decision-making. To demonstrate the usefulness of LQR as an inclusive methodology, we discuss an ongoing study of career decision-making among a diverse cohort of biomedical scientists. We have used annual interviews to follow biomedical science trainees from the beginning of their PhD into the initial stages of their careers. We present case studies of minoritized scientists to illustrate the methods for long-term engagement used to elicit sensitive and critical information during their training. We show how LQR is a viable methodology for a variety of research questions and can be accomplished using large or small sample sizes and limited resources. Our primary goal is to show how LQR is useful to understand the experiences of minoritized individuals in contexts that have historically excluded them.
