This document provides an overview of schema therapy. It discusses how schemas develop from unmet emotional needs in childhood and shape maladaptive behaviors and lifetraps in adulthood. Eighteen early maladaptive schemas are organized into five domains: disconnection/rejection, impaired autonomy/performance, impaired limits, other-directedness, and overvigilance/inhibition. Lifetraps perpetuate schemas through cognitive distortions, self-defeating patterns, and coping styles. The goal of schema therapy is to help patients overcome schemas and lifetraps to better meet core emotional needs.
