This book aims to articulate and problematise mental health care production actions in primary care in the municipality of Parnaíba-PI, based on my professional internship practice during my undergraduate degree in Psychology at UFPI and the territorial practices carried out through the Collective Health Observatory extension project. Among the objectives proposed by the study, we highlight the importance of getting to know the mental health care practices of a Family Health Strategy (ESF) and the actions developed, identifying the assistance offered to cases by workers, and ascertaining how the family and the team deal with the person in psychological distress. We also highlight the reflections and dialogues relevant to the struggle to strengthen public mental health policies within the psychiatric reform process, demonstrated through the social commitment that the state, professionals and users must seek on a daily basis to consolidate practices involved with the quality of services and the provision of humanised care for people with mental disorders.
