Psychologists in public health: Historical aspects and current challenges.

This article presents the historical context of the insertion of psychology, as a profession, in health policies in Brazil, in order to understand its current challenges. Analysis was based on a non-systematic literature review about professional training, practice, and research in psychology. Three challenges were identified: working in high social vulnerability contexts, practice in multidisciplinary teams and the need to expand the research agenda. We conclude that dealing with these challenges will depend on the area’s capacity to reinvent itself and become more permeable to interdisciplinary dialogue.
