In population health research, it is important to consider socioecological perspectives that include cultural attitudes and beliefs which permeate all levels (intrapersonal, interpersonal, institutional/community, and structural/ policy). Given the specificity of target populations centered on identity – ethnic and others – it is appropriate and warranted to centralize cultural studies theories into health determinant investigations. Cultural studies, which focus explicitly on identity exploration and impacts, have much to contribute to health research. In accordance with the transdisciplinary nature of population health and bearing in mind the significant role of ethnic identity in health outcomes, it is beneficial to utilize critical race theory (CRT) as a theoretical framework and analysis tool for population health research. This article will: (1) briefly overview a recent mental health study employing CRT, and a commentary that emphasizes how CRT can contribute to the sociology of mental health; and (2) propose ways CRT can be used in psychosocial health research.
