Reframing the National Institute on Minority Health and Health Disparities Research Framework: Strengthening the Behavioral Domain with the Inclusion of Psychological Factors.

The National Institute on Minority Health and Health Disparities Research Framework (NIMHD-RF) provides a multidimensional structure to examine health disparities across domains and levels of influence. While influential, its current Behavioral Domain centers on observable behaviors and underrepresents key psychological factors and determinants that shape health outcomes among minoritized populations. This gap limits the framework's capacity to account for complex factors such as internalized stigma, identity-related stress, and cultural processes that significantly contribute to mental health disparities. In this viewpoint, we propose an adaptation of the Behavioral Domain into a Psychological/Behavioral Domain to better reflect the interconnected psychological, biological, sociocultural, and environmental factors influencing health. The revised domain incorporates psychological vulnerabilities, coping strategies, and identity-based stressors across all levels of influence, from individual to societal, and acknowledges macro-level processes such as structural stigma and inequitable policies. This reframing emphasizes that behaviors are shaped by psychological experiences and systemic inequities, not merely individual choice. By explicitly integrating psychological factors and determinants, the framework becomes more robust in guiding culturally responsive, equity-driven research and interventions. This adaptation aims to enhance the framework's utility in mental health disparities research and to support efforts to achieve health equity for historically underserved populations.
