Structural barriers perpetuate mental health disparities for minoritized US populations; global mental health (GMH) takes an interdisciplinary approach to increasing mental health care access and relevance. Mutual capacity building partnerships between low and middle-income countries and high-income countries are beginning to use GMH strategies to address disparities across contexts. We highlight these partnerships and shared GMH strategies through a case series of said partnerships between Kenya-North Carolina, South Africa-Maryland, and Mozambique-New York. We analyzed case materials and narrative descriptions using document review. Shared strategies across cases included: qualitative formative work and partnership-building; selecting and adapting evidence-based interventions; prioritizing accessible, feasible delivery; task-sharing; tailoring training and supervision; and mixed-method, hybrid designs. Bidirectional learning between partners improved the use of strategies in both settings. Integrating GMH strategies into clinical science-and facilitating learning across settings-can improve efforts to expand care in ways that consider culture, context, and systems in low-resource settings.
