Dialectical Behaviour Therapy
Dialectical Behaviour Therapy (DBT) synthesizes principles from behaviourism, Zen, and dialectics. Originally developed to address the comprehensive problems of adult women with a diagnosis of borderline personality disorder (BPD) and repetitive suicidal and self-harming behaviours, the flexibility of its principle-driven approach has led to its deployment in treating a wider range of client groups and in more varied settings than was originally conceptualized. This chapter begins by briefly describing the origins of DBT and orients the reader to the handbook by describing distinctive features of the treatment in terms of its theoretical foundations, structure, and clinical features. Developments over the last 25 years in the evidence-base, adaptations, and implementation of DBT and where these are addressed in the Handbook are subsequently outlined.
