The aim of this article is to discuss the work of the mental health teams in the Child and Adolescent Psychosocial Care Centers (CAPSi), in order to consider subjectivity as a factor of inclusion. The methodology used was based on applied psychoanalysis. Franco Basaglia's contributions were revisited in order to understand his influence on the Psychiatric Reform in Brazil and to elucidate the current practice of CAPSi. The current impasses in the field of subjectivity in the Psychiatric Reform are discussed and it is proposed to locate transversal surfaces that articulate the presence of a psychoanalytic approach to subjectivity in psychosocial care. The conclusion is that it is important to discuss a psychoanalytic approach to subjectivation in public mental health services, so that treatment in these services is not polarized between biological reductionism and psychosocial care.
