This book helps us to understand the therapeutic processes involved in the multifamily group and gives us tools for effective management, making it an indispensable guide for professionals in all areas of human care who are interested in including multifamily therapy in their institutions. In recent years we have witnessed the emergence of forms of social and health care that incorporate the voices of the people who suffer and those of their family and social environment as a therapeutic resource. These include Multifamily Therapies, therapeutic interventions carried out through groups made up of several families (multifamily groups) in which the mechanisms of family therapy and group therapy mutually enhance each other. Among the various models of multifamily therapy, Interfamily Therapy has become the most widespread. It is an integrative and eclectic model inspired by attachment theory and dialogical practices and represents a new way of approaching human problems through sharing and learning together with others. The simplicity of its theoretical statements and methodology facilitates its application in any social, educational and health context by professionals from different backgrounds.
