Station brief
Format. Communication station, approximately 7–10 minutes active time after reading. You are the forensic psychiatry registrar. The examiner plays the adult sibling of a patient in medium security. [1]
Candidate instructions. Explain how the team assesses risk before leave using plain language. Cover structured assessment (not just a score), history vs current changeable factors, strengths/protective factors, conditions of leave, what would stop leave, and residual uncertainty. Avoid equating mental illness with permanent dangerousness. Do not invent specific Mental Health Act section numbers. Check understanding and invite questions. [1][3][4]
Candidate scenario
The sibling says: "The report mentioned a high actuarial score because of his past assaults. Does that mean he can never have leave? We are scared of him being labelled a monster forever, but we also need to know the neighbour is safe. What exactly are you looking at before leave, and will we be told if something goes wrong?" The patient has schizophrenia, improved on medication, and has had negative drug screens recently. [2][5]
Marking domains
- Empathy; non-stigmatising language
- Explains multi-source structured assessment (history, current mental state, future plans)
- Distinguishes static scores from dynamic and protective change
- Describes leave as graduated testing with conditions (substances, medication, victim access)
- Explains residual uncertainty without false reassurance or fatalism
- Addresses neighbour/public safety and information-sharing principles (not invented statutes)
- Checks understanding; invites questions [1][3][4]
Reveal assessor key
Open. Thank sibling; acknowledge fear and hope; set time/purpose; validate that most people with schizophrenia are not violent while taking past assaults seriously. [5]
Explain method. We review files and talk with your brother and the team. We use structured frameworks looking at past history, how he is now (symptoms, insight, substances), and what the leave plan looks like (supports, stress, who he might meet). Tools can rank group risk from history; they do not decide alone. [1][4]
Static vs dynamic/protective. The high actuarial band reflects past violence and will not vanish. What can change is illness control, drug-free status, engagement, coping, and supports — these improvements are linked to better outcomes after forensic treatment. Leave is earned stepwise, not by ignoring the past. [2][3]
Conditions and safety. Leave may start escorted; drug tests; no contact with the neighbour if that is a risk; clear stop rules if substances or symptoms return. Multi-agency partners may be involved when needed for public protection under local law. We cannot promise zero risk; we manage and monitor it. [1][4]
Close. Summarise; invite questions; offer appropriate contact points within confidentiality rules. [4]
