About The Program

The COVID-19 HEalth caRe wOrkErS (HEROES) study is an ongoing, global initiative, aimed at evaluating the impact of the COVID-19 pandemic on the mental health of clinical and non-clinical health-care workers in more than 20 countries. HEROES was originally conceived, developed, and scaled by a team of early career collaborators mentored by Drs. Ezra Susser at Columbia University and Rubén Alvarado at the University of Chile. The study is still mostly driven by these collaborators, many of whom are from or live in LMICs. Our team approach is based on cooperative leadership and mutual learning principles, which, we believe, has contributed to creating a truly collaborative and friendly relationship between investigators from the South (Latin America, Africa, and Asia) and the North (the US, Europe). For instance, most of our research materials (e.g., web-based survey, study protocol) have been designed, translated, and adapted almost simultaneously in all the participating countries and close partnership between LMIC and HIC teams. The bulk of this work has been done by young investigators, who are more likely to establish horizontal relationships, which would have been difficult to achieve in a more standard research setting. We believe that this unusual but highly valuable arrangement contributes to reimagining the South-North collaborations and transforming the usual power structures and practices in Global Mental Health.
