Objective. Present the results of a pedagogical intervention to improve the quality-responsiveness in healthcare provided by health service providers in indigenous regions. Materials and methods. A didactic methodology with a critical-constructivist approach was designed aimed to health personnel who attend to the indigenous population in five entities of Mexico. Results. Between 09/2016 and 01/2020, 1 825 health workers were trained, who deconstructed the beliefs that determine practices of discrimination and abuse during the health care of indigenous users. The intervention achieved significant transformative learning of social beliefs and practices, with proposals to avoid any form of abuse and guarantee dignified treatment. Conclusions. For the construction of a universal and equitable health system, it is necessary to include interventions that act on the beliefs that determine discrimination and mistreatment practices in health services towards vulnerable social groups.
