Matrix support comprises an organizational arrangement that aims to bring assistance and technicalpedagogical support to the Family Health Strategy teams by a multi-professional team. This strategy aims to guide new practices in health. The growth of the number of psychologists in these services is observed, what is due to difficulties in dealing with the users' mental health problems according to family health practitioners. This descriptive study aims to investigate the matrix support psychologists' perceptions of their activities, and whether they correspond to the guidelines established by SUS. About 10 psychologists, with ages that range from 23 to 45 years old, were interviewed. The results demonstrate that despite there is a tendency for psychologists to adopt the new practices, they show beliefs and practices based on the biomedical paradigm. The matrix support as a device for change has not yet been applied by these professionals, revealing that there is still a long way to go in order to reach this ideal.
