Mental Health and Psychosocial Intervention:

A Mapping of Scientific Production

Abstract

The objective of this article is to synthesize the available scientific evidence on psychosocial interventions in mental health, identifying their main modalities, target populations, effectiveness, and implementation challenges, through na integrative review conducted in the PubMed, SciELO, PsycINFO, and LILACS databases. Controlled descriptors and keywords were used, and articles published between 2015 and 2025 were included. The synthesis of the studies highlighted four central themes: the organization of the Psychosocial Care Network in the face of high demand for mental health care; the challenges of psychosocial care, with emphasis on the illness of professionals and prejudice against users; the profile of users and the determinants of social vulnerability; and the barriers to access and their implications for the effectiveness of care. It was observed that psychosocial interventions have a positive impact on promoting autonomy, psychosocial rehabilitation, and reducing harm; however, their effectiveness remains limited by the precariousness of services, insufficient resources, and the persistence of stigma associated with mental suffering. The need to strengthen interdisciplinary work, intersectoral coordination, and the expansion of public policies aimed at vulnerable populations is highlighted. Focusing on the Psychosocial Care Network and Psychosocial Care Centers, the study highlights the importance of Primary Care as the organizer of mental health care. It concludes that guaranteeing the rights ensured by the Psychiatric Reform demands continuous investment, professional qualification, and addressing social inequalities for the effective consolidation of care in freedom within the Brazilian Unified Health System (SUS) in contemporary Brazil and in diverse local contexts.
