In the last decade, in the United States, family therapy has ceased to be an experimental process, used in specialized places, and has become one of the therapeutic modalities that is practiced in mental health centers," the author says in the prologue for the Spanish edition. The influence of this book and Dr. Minuchin, among other factors, has made this therapeutic modality an incontrovertible reality in Spanish-speaking countries today.
In Families and Family Therapy the individual is considered as a subsystem in the family package, whose modifications contribute to the production of changes in behavior. In therapy, the therapist associates with the system and utitizes the person to transform it. This trial provides the main theoretical notions of this technique supported by the case study, conducted by Dr. Minuchin at the helm of the Philadelphia Child Guidance Clinic.
