The Partners in Health (PIH) Cross-Site Mental Health Program and Mental Health Learning Collaborative (MHLC) focuses on increasing the reach and quality of evidence-based, culturally adapted, mental health services and ensures that health systems are equipped to support and manage quality mental health care. Through the MHLC, PIH site teams have expanded access to care, improved the quality of services, and piloted implementation strategies to strengthen the scope of mental health services provided to their communities. Using this funding, Socios en Salud (the Peru-based office of PIH) will lead the scale-up and digitization of the MHLC across nine PIH sites (Liberia, Lesotho, Mexico, Peru, Malawi, Haiti, Rwanda, Sierra Leone, Kazakhstan) to reinforce global south-south collaboration.
