DBT and third-wave therapies — structured clinical viva

You are the psychiatry registrar. A 24-year-old with recurrent self-harm, affective storms lasting hours, and fear of abandonment is referred for 'third-wave therapy'. Discuss what third-wave means, deliver the full DBT skeleton (modes, modules, stages, hierarchy), explain biosocial theory, summarise landmark evidence including McMain, contrast ACT and MBCT indications, and describe phone coaching and consultation-team functions. Address what you would do if only a skills group is available.
