Dialectical Behaviour Therapy (DBT) was originally developed for which condition, and which core module specifically addresses the 'swing' between emotional vulnerability and invalidating environments?
- A Borderline personality disorder; the biosocial theory as the theoretical underpinning, not a separate 'swing module' ✓
- B Borderline personality disorder; distress tolerance module
- C Chronic PTSD; trauma-processing module
- D Bipolar disorder; interpersonal effectiveness module
Correct answer: A. Borderline personality disorder; the biosocial theory as the theoretical underpinning, not a separate 'swing module'
Explanation
DBT (Marsha Linehan) was developed specifically for borderline personality disorder. The biosocial theory proposes that BPD arises from the transaction between biological emotional vulnerability (sensitive, reactive temperament) and a chronically invalidating environment. DBT does not have a single 'swing module'; rather, the dialectical stance (acceptance vs. change) permeates all four skill modules: mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. The biosocial theory is the theoretical foundation, not a treatment module.
