ABSTRACT
This chapter presents an overview of the intersystem approach (IA) as the conceptual framework and introduces the integration of attachment theory as a new construct within the IA, especially as it applies to the intergenerational domain of the IA. It summarizes the key developments and concepts of the IA as an integrative approach that allows the clinician to draw together multiple theories in understanding and treating client-systems. The IA is an integrative approach to treatment, and it allows the clinician to transcend any particular model of individual or relational therapy by focusing on multiple aspects of the client-system and by linking intergenerational transmission of attachment processes to all facets of human development. After many years of refinement, application, and reconsideration, the IA is still an evolving integrative paradigm for systemic assessment and treatment.
