Many therapeutic and preventive approaches focus on symptom reduction and behavioral change—but lasting change only occurs when people learn to combine emotional regulation with the systematic development of self-competence. The Emotion-Based Self-Competence Method (ESM) offers precisely that: a comprehensive development model that combines neurobiological findings with a clear, practice-oriented intervention concept. At the heart of ESM is the self-competence model according to Salig/Theissler, which enables the systematic development of the ability to understand, control, and value oneself. ESM combines these dimensions with the ability to use emotions as a resource – thus creating the basis for profound, sustainable change processes. This reference book systematically introduces ESM – from the theoretical foundations and the self-competence model to concrete intervention steps and their application in different settings. It is aimed at psychotherapists, counselors, coaches, educators, and anyone who works with people in prevention or therapy. • Well-founded presentation of the neurobiological and psychological foundations of emotional self-regulation and self-competence development • The self-competence model according to Salig/Theissler with its five central elements • Step-by-step instructions for the practical application of ESM • Numerous case studies from therapy and prevention • Differentiated consideration of various disorders and application contexts ESM opens up new avenues in therapeutic and preventive work: from reactive patterns to conscious self-control. From symptom treatment to personality development.
