Various studies describe the Singular Therapeutic Project (STP) as a powerful instrument of care for the users of specialized mental health services. It is also put forward as a tool to organize and support the activities of the Family Health Support Centers (FHSC), based on the concepts of co-responsibility and comprehensive care. The article seeks to analyze the development of STP by mental health teams of FHSC and its articulations with services of Primary Health Care (PHC), psychosocial services and other sectors of society. It involved qualitative research performed in Guarulhos in the state of São Paulo in 2012 by systematic observation and conducting semi-structured interviews with mental health professionals from support centers. The content analysis method was employed for interpretation of the findings. The STP in FHSC faces obstacles related to lack of definition of work object (attention or management?), precarious working conditions and overlapping functions. It is necessary to analyze the technological feasibility of the STP based on the peculiarities of PHC, avoiding straightforward transposition of technological tools among the different services that comprise the psychosocial care network.
