Formulation skills — structured clinical viva

You are the psychiatry registrar. A 34-year-old woman presents with 4 months of major depression after redundancy. She drinks a bottle of wine most nights 'to sleep', lies in bed until midday, and has passive death wishes without a plan. She describes childhood emotional neglect, a critical mother, and a partner who wants to help but 'keeps saying snap out of it'. She is proud of being a good parent to a 8-year-old. Discuss your formulation framework, a 4P biopsychosocial formulation, cultural/identity issues you would explore, how formulation differs from diagnosis and from risk assessment, critiques of the BPS model, and how you would present this in under 90 seconds in a CASC.
