Originally developed to treat suicidal individuals with borderline personality disorder, Dialectical Behavior Therapy (DBT) has since been adapted to a range of settings and populations. This book brings together leading experts to describe how to set up a DBT program and implement this cost-effective, evidence-based treatment with adults, adolescents, couples and families, and forensic clients. Applications are presented for depression, substance dependence, eating disorders, psychosis, suicidal and assaultive behaviors, and other complex, difficult-to-treat problems. Each chapter has been rigorously reviewed for both real-world practical utility and adherence to DBT principles. Special features include over a dozen reproducible worksheets and forms.
