For the average clinician, individuals with borderline personality disorder (BPD) often represent the most challenging, seemingly insoluble cases. This volume is the authoritative presentation of dialectical behavior therapy (DBT), Marsha M. Linehan’s comprehensive, integrated approach to treating individuals with BPD. DBT was the first psychotherapy shown in controlled trials to be effective with BPD. It has since been adapted and tested for a wide range of other difficult-to-treat disorders involving emotion dysregulation. While focusing on BPD, this book is essential reading for clinicians delivering DBT to any clients with complex, multiple problems.
