The family is a central theme in human life. The numerous changes that have occurred in this institution—divorces and various types of families—particularly in recent decades, have triggered a plethora of research from various scientific fields to investigate the factors that led to these changes, the effects on family members, and the reinforcement of processes related to the creation of healthy families, regardless of their form.

Boundaries are a fundamental concept in the functioning of the systems established since the inception of the systemic approach. They refer to the factors, properties, and processes that define the identity of a system and differentiate it from other subsystems. The study of boundaries in the family allows for the exploration of the processes and factors associated with the initial creation of the family system and the shaping of its identity, its functioning, as well as its evolutionary trajectory.

This choice also enables the study of issues concerning the creation of the couple and their relationship, the individual and the shaping of their personality, and the family as a whole. The highlighting of the processes by which these fundamental subsystems are formed and operate simultaneously provides the principles and methods for intervention and therapy where problems exist.

Due to the information provided about the basic principles of the systemic approach, which apply not only to the family but also to other biopsychosocial systems, this book serves as a useful aid for teaching the systemic perspective.
