In the past six decades, extensive research has been done on family therapy from different areas of knowledge such as psychology, psychiatry and social work. Leading to development of different intervention techniques and optimal clinical evaluation with families.

The systemic perspective focus on the study of the dimensions that contribute to the stability and consistency of the members of the family system. The family is an interrelated system, dependent on each other, where there is an influence of the group over the individual, which is why each of its members plays a pivotal role in family therapy. Throughout all these years of evolution of systemic family therapy, many different concepts and techniques have been used, including the ones currently used today.

Knowing the evolution of the different techniques allows us to understand the functioning of families, for example, their links and the elements that constitute it: their roles, the functions performed by each member in the family, communication, standards and power relations.

The descriptive diagnosis of family ties, help us implement intervention strategies that could improve clinical care and diagnostic approach.
