Talking about family practice is talking about family systemic approach. There are many cues that are so important to understand how the family functions. This is the scope of systemic family approach, where the health is influenced by all the systems a person belongs. In this chapter, we will discuss how a family interacts and the roles of every person in the family-as individuals and as part of the context. And most of it is how this interaction influences the health of every member of the family. Based on the systemic theory, we will run over some tools that will allow to assess the family and discuss how to ease the communication and to help the family to face their difficulties.
