Book excerpt: Schema Therapy (ST) was developed to treat patients with complex disorders, especially personality disorders, with a powerful new set of interventions. Personality disorders, as well as more general problems stemming from early experience and addressed by schema therapy, are a key factor in many disturbed relationships, and as a result ST is now increasingly used for couples work. By dealing effectively with the past, ST offers a unique way to approach and address present difficulties in relationships, Couples who understand their individual patterns of thinking and behavior tend to find that their relationships make much more sense. Breaking Negative Relationship Patterns is a readable, practical resource containing a wealth of self-help exercises that schema therapists can recommend or give to their patients. It is the ideal resource for couples undergoing schema therapy, ­and can also serve as an accessible self-help guide for those experiencing relationship difficulties. The authors offer a complete ST-based model for understanding complex personal problems, along with couple-specific adaptations of core ST interventions such as limited reparenting, imagery re-scripting and behavioral pattern breaking.
