One goal of qualitative health research is to fully capture and understand stories of people who experience inequities shaped by complex interlocking structural and social determinants. With this social justice–oriented goal in mind, it is critical to use a methodological approach that appreciates prevailing inequities and oppression. In this article, we propose an innovative approach that joins qualitative health research methodology with critical inquiry. Specifically, we propose advancing constructive grounded theory (CGT) through applying intersectionality as an emergent critical social theory and an analytical tool. With our proposed approach being novel, minimal attempts to conceptualize and operationalize CGT with intersectionality exist. This article focuses on initiating theoretical conceptualization through focusing on demonstrating congruency. We are guided by this focus to seek connectedness and fit through analyzing historical and philosophical assumptions of CGT and intersectionality. In our article, we demonstrate congruency within four units of analysis: reflexivity, complexity, variability, and social justice. Through these units, we offer implications to applying intersectionality within CGT methodology. These include a foundation that guides researchers toward further conceptualizing and operationalizing this novel research approach. Implications also include innovatively exploring complex population groups who face structural inequities that shape their lived vulnerabilities. Our proposed research approach supports critical reflection on the research process to consider what shapes the researcher–participant relationship. This includes reflecting on analysis of power dynamics, underlying ideologies, and intermingling social locations. Thus, our conceptual paper addresses the call for evolving social justice methodologies toward inquiring into complex populations and generating knowledge that challenges and resists inequity.
