This textbook provides a comprehensive and in-depth exploration of the primary models of family therapy and helps readers conceptualize various theories around a single case. Designed as a core text for marriage and family therapy courses, this edited volume presents the conceptualization of problem formation, problem resolution, and diversity considerations from 15 of the most influential family therapy models. By applying traditional and contemporary models to a single case, the reader is able to compare and contrast the models. Each theory chapter is divided into five parts: 1) the therapeutic story of problem formation; 2) diversity considerations; 3) the therapeutic story of problem resolution; 4) a hypothetical case transcript of a first session with explanations of how and why the therapist is creating a specific therapeutic story; and 5) the developed therapeutic story. This textbook serves graduate and doctoral students in marriage and family therapy, mental health counseling, clinical psychology, and social work. The book is also a useful resource for practicing professionals who want to explore how to apply a specific model of counseling to family systems.
