Integrative Strategic Psychotherapy Vol.1: Theoretical Foundations - Oana Maria Popescu

The Integrative Strategic Psychotherapy series was conceived as both a comprehensive training manual and a continuing professional resource for psychotherapists at all stages of development. Across its six volumes, the series aims to accompany the reader through the evolving landscape of integrative and evidence-informed psychotherapy, blending theoretical depth with clinical practicality. The series provides a structured and coherent learning path for students and supervisees who wish to understand and apply the Integrative Strategic Psychotherapy (ISP) model in their practice. At the same time, it serves as a reference and reflective resource for experienced psychotherapists seeking to deepen their understanding of integration, refine their technique, and ground their clinical decisions in a theoretically unified framework. Each volume addresses a distinct aspect of the model-from its theoretical and philosophical foundations, to assessment, formulation, and intervention strategies, to its application in specific clinical areas. Together, the volumes form a cohesive body of knowledge that bridges neuroscience, developmental psychology, and the relational traditions of psychotherapy. The ISP model integrates multiple dimensions of human functioning: biological, psychological, and relational levels intersect with cognitive, emotional, and psychodynamic axes. At its centre lies the conception of the self as a dynamic and evolving structure, encompassing the proto, core, plastic, and external domains. This framework allows for a flexible yet disciplined approach to therapeutic understanding and intervention-one that honours both the complexity of the human psyche and the uniqueness of each client’s story. The intention is not only to teach a model, but to cultivate an integrative mindset-one that values creativity, critical thinking, and relational authenticity as much as technical skill. Whether used as a training manual, a supervision companion, or a source of inspiration for ongoing clinical reflection, the Integrative Strategic Psychotherapy series invites psychotherapists to engage in a process of lifelong integration: between theory and practice, self and other, science and art.
