Explain FEP homicide risk and responsibility to a worried family — CASC communication station

Station brief

Format. Communication station, approximately 7–10 minutes active time. You are the psychiatry registrar speaking with parents after an early-psychosis assessment clinic visit. [1]

Candidate instructions. Acknowledge fear without amplifying stigma. Explain that absolute risk of homicide is low even though relative risk of violence can be raised. Explain why untreated first-episode psychosis is the period of greatest concern in homicide research among psychotic cases. Cover warning signs (threat content, substances, family fear, weapons access). Outline urgent assessment/treatment pathways. Clarify that a schizophrenia diagnosis is not the same as a legal insanity finding. Do not invent statute numbers. Check understanding and safety plan. [1][2][3][5]

Candidate scenario

Parents say: "We saw a documentary — people like him kill their families. If he has schizophrenia he will definitely be found insane if anything happens, right? Should we lock him up forever? He thinks we are poisoning him and he has been drinking more. What do we do tonight?" [1][4]
