Systemic barriers to cultural knowledge integration in mental health practice

In this theoretically driven narrative review, we examine epistemic injustice-specifically the systemic marginalization of certain groups as knowers and the inadequacy of dominant interpretive frameworks for accurately understanding their experiences. We explore how these dynamics manifest within Western mental health training and practice with the aim of advancing the theoretical application of the framework and developing recommendations for practice and institutional reform. We applied Miranda Fricker’s epistemic injustice framework to peer-reviewed literature published in PsycINFO and PubMed from 2000 to 2025 with the following terms: “epistemic injustice,” “testimonial injustice,” “hermeneutical injustice,” “cultural competency,” “traditional healing,” “mental health disparities,” “Indigenous psychology,” and “multicultural therapy.” The review is theoretically driven rather than systematic; source selection was iterative and judgment-based, and was informed by ongoing critical reflexivity regarding the authors’ positionality relative to the communities described. Approximately 88 sources are drawn upon. The guiding research question is: how does epistemic injustice theory illuminate the structural mechanisms that sustain mental health disparities across diverse communities? Epistemic injustice operates through three interconnected levels: the exclusion of non-Western epistemologies in mental health training, testimonial and hermeneutical injustice in clinical encounters, and institutional mechanisms—including insurance structures, credentialing requirements, and evidence standards—that reproduce and reinforce the first two. These patterns are structural rather than incidental. We offer recommendations for transforming training programs, expanding the evidence framework, reforming institutional policies, and developing collaborative practice models that respect diverse healing traditions while addressing the epistemic conditions that sustain mental health disparities. Despite decades of cultural sensitivity training, mental health disparities persist across racial, ethnic, and sexual and gender minority communities, with Indigenous, Black, Latinx, Asian American, and 2SLGBTQIA+populations facing barriers to effective care. This paper shows how mental health systems systematically exclude non-Western healing practices and ways of understanding psychological distress through institutional policies. Addressing these knowledge-based barriers through institutional reform offers a pathway to reduce disparities and better serve diverse communities.
