Personality disorders are categorised into three ? clusters? , each containing several specific disorders with common characteristics that differentiate them from those contained in the other clusters. Schema therapy was developed primarily to manage and treat ? cluster B? personality disorders, especially borderline personality disorder, and it has a robust evidence base in this area. Research studies have shown that schema therapy is also an effective treatment for clients with ? cluster C? personality disorders ? dependent personality disorder, avoidant personality disorder and obsessive-compulsive personality disorder ? but only if a number of important adaptations and adjustments to the treatment protocol are made. Written by well-known experts in the field, this is the first book to explore the theory and practice of using schema therapy to treat individuals with ? cluster C? personality disorders.Part of the Schema Therapy Approaches and Resources series, following the success of Chairwork, Imagery Rescripting and Schema Therapy: A Phase-Oriented Approach.
