This study examines how culturally competent crisis intervention in underserved U.S. communities can affect mental health outcomes. Mental health disparities in marginalized groups, including racial and ethnic minorities and low-income individuals, continue to be substantial, and culturally competent care has been viewed as a primary approach to addressing these disparities. This study reviews peer-reviewed literature published from 2005 through 2024 that examines the impact of cultural tailoring on mental health crisis outcomes. A systematic review of the relevant literature was conducted, primarily including studies of cultural competence in mental health crisis interventions. The analysis concluded that culturally competent services greatly improve delivery and access, especially in historically marginalized and oppressed communities. Overall, our results show these interventions are effective in improving communication, building confidence, and reducing the stigma of seeking mental health care, thus contributing to a better patient-provider relationship and outcomes for long-term recovery. Nevertheless, numerous roadblocks to implementation exist, such as a lack of resources, inadequate provider training, and structural or cultural barriers within healthcare systems. The educational memory of community-based mental health services has reflected the reality of a working model of high-performance mental health outreach, where the ability to make adaptations that fit the profiles you meet as you deploy the departments responsible for each crisis period provides solid usefulness in a country with a large, diverse population. The recommendation highlights the need for policymakers to consider cultural competence and capacity in mental health care and the importance of ongoing training of providers, community engagement in designing mental health programs, and resources for implementing culturally relevant mental health interventions. Our recommendations are related to the improvement of mental health in underrepresented populations throughout the United States.
