Objective: to know and analyze the trend of Brazilian scientific production on the Singular Therapeutic Project in Psychosocial Care Centers. Methodology: this is a narrative review of the literature, carried out on the theses and dissertations portal of the Coordination for the Improvement of Higher Education Personnel, in June 2022. Results: the Singular Therapeutic Project provides the user and their family with the protagonism in care, making them co-responsible for it. The instrument is based on the use of light technologies, such as listening and welcoming, which corroborates the emancipatory care in mental health. It enables the services of the psychosocial care network to move towards the management of mental health care based on the humanized, integral and equitable health model. Furthermore, the Singular Therapeutic Project appears as an important way to build public policies based on the real needs of the territories and assisted users. However, it is known that there are still important challenges facing the construction of the instrument, which directly impact the democratic management of the instrument. Final considerations: the study made it possible to know the scientific productions of graduate programs about the Singular Therapeutic Project in Psychosocial Care Centers, which predominantly use qualitative research methods. Furthermore, it made it possible to identify the weaknesses that still exist in the services of the care network, providing a basis for the development of future research and actions in the field of mental health.
