Therapy-interfering behavior (TIB) is a key treatment target in dialectical behavior therapy (DBT), second only to suicidal thinking and self-harm. This wise, engaging book gives clinicians everything they need to assess, understand, and address TIB both in clients and in themselves. Therapists learn how to orient clients to TIB and work with it effectively whenever it shows up, using a combination of validation, contingency management, and dialectics. Packed with clinical examples, dialogues, and practical tips, the book discusses the full range of DBT contexts, from individual therapy to skills class, phone coaching, and consultation teams.
