Designed to bring about lasting change in clients with personality disorders and other complex difficulties, schema therapy combines proven cognitive-behavioral techniques with elements of other widely practiced therapies. This book--written by the model's developer and two of its leading practitioners--is the first major text for clinicians wishing to learn and use this popular approach. Provided in one comprehensive volume are an authoritative conceptual overview and step-by-step guidelines for assessment and treatment. Clinicians learn innovative ways to rapidly conceptualize challenging cases; explore the client's childhood history; identify and modify self-defeating behavioral patterns; use imagery and other experiential techniques in treatment; and maximize the power of the therapeutic relationship. Including detailed protocols for treating borderline personality disorder and narcissistic personality disorder, the book is illustrated with numerous clinical examples.
