This article reports a qualitative approach research on the integration of psychology in the Family Health Strategy (ESF) of the Unified Health System (SUS) in Brazil. A questionnaire with seven psychologists enrolled into multiprofessional residence courses in the Family Health Strategy from four cities in Brazil and field notes by the main author, in his experience as a psychologist and resident, were used to investigate issues that are relevant to this field of psychological performance. Considering the empirical investigation, the article highlights the role of psychology in the SUS and ESF, discusses the advances and difficulties found and systematizes activities that were developed by the participants. Finally, the research questions the role historically held by the Public Health Psychology, pointing to the emergence of a work toward social change as a fertile way to integrate psychologists into the Primary Health Care.
