Prompt
A recently evacuated adult in a crowded shelter after a bushfire; you must engage compassionately, assess suicide risk and exposure, distinguish acute distress from evolving disorder without pathologising, offer Psychological First Aid principles and practical supports, avoid forcing a graphic trauma dump or promising mandatory debriefing, and agree a stepped follow-up plan.

Station brief

Format. Communication station, approximately 7–10 minutes active time after reading. You are the psychiatry registrar attached to the evacuation centre mental health team. Privacy is limited; negotiate a quieter corner. [4]

Candidate instructions. Build rapport. Assess suicide risk. Map exposure and current practical needs. Normalise early distress without dismissing severe symptoms. Explain PFA-style support and that not everyone needs specialist trauma therapy immediately. Do not force a full graphic narrative. Do not offer mandatory group debriefing as prevention. Agree a collaborative safety and follow-up plan. [1][2][3]

Candidate scenario

Your patient is 42, evacuated last night from a high-impact bushfire zone. Lost home; partner safe; neighbour deceased. Reports little sleep, jumpiness at sirens, tearfulness, and saying "I keep seeing the sky turn black — maybe I should not be here." No prior psychiatric admissions. Taking no regular medication. Sobbing but oriented. No acute medical emergency. Interpreter not required. [4]

Marking domains

  • Introduces self/role; protects privacy as far as possible in a shelter
  • Explicit suicide risk assessment (ideation, intent, plan, means, protective factors)
  • Trauma-informed pacing; offers control and breaks; no forced graphic dump
  • Exposure and loss enquiry including practical needs (housing, clothing, information)
  • Explains normal early distress vs when further help is needed; names support without promising CISD cure
  • Collaborative plan: safety tonight, centre supports, primary care/crisis follow-up, pathway if symptoms persist (skills help → trauma-focused therapy; medication discussion only if appropriate)
  • Empathy, time management, non-pathologising language [1][3][4]
Reveal assessor key

Open. Introduce; explain role with the mental health team; negotiate quieter space; check who should be present. [4]

Risk. Passive/active ideation, intent, plan, means, protective people, substances, safety tonight in the shelter. [4]

Explore. "What has been hardest since the fire?" (paced). Losses, sleep, startle, alcohol, children/dependents. "What would help most today?" (information, reunification, quiet place, contact with GP). Promote safety, calm, connectedness, efficacy, hope in plain language. [1][3]

Plan. Safety plan; centre welfare supports; follow-up check; explain that many improve with support and time, while persistent nightmares/avoidance/depression warrant stepped specialist care. Do not mandate debriefing group. Medication (e.g. sertraline pathway) only if clinically indicated and preferred later — not a day-one sales pitch. [2][5]

Fails. Forcing graphic retelling; "everyone needs CISD today"; skipping risk; diagnosing lifelong PTSD in the first minutes; inventing legal sections; dismissing all distress as "just stress" without a follow-up plan. [2][4]
