Virtually all significant relationships are shadowed by a third party another person, a competing distraction, or even a memory. This groundbreaking book provides clinicians with a hands?on guide to working with many different kinds of relationship triangles in therapy with families, couples, and individuals. The authors show why triangles come into being, how to predict their evolving nature, and how they can be dealt with and resolved in treatment. A wealth of clinical case material and treatment suggestions illustrates how thinking in terms of threes, as well as individuals and dyads, can greatly increase therapeutic flexibility and effectiveness. This book will be of interest to therapists from a range of backgrounds working with families, couples, and individuals, as well as students of psychotherapy and counseling. It serves as a text for courses and training programs in individual, couple, and family therapy.
