Station brief
Format. Communication station, approximately 7–10 minutes active time. You are the child and adolescent / community psychiatry registrar after a clinic review. [2]
Candidate instructions. Acknowledge fear without amplifying stigma. Explain firesetting as behaviour, arson as a legal label if charged, and pyromania as a rare adult-oriented diagnosis that usually does not fit youth fireplay patterns. Note that youth firesetting can associate with broader later offending pathways and needs structured help, not panic labels. Cover safety (means restriction, supervision, school/fire-service liaison as appropriate). Screen briefly for mental illness, substances, bullying, and home conflict. Do not invent statute numbers. Check understanding. [1][2][3][4]
Candidate scenario
Parents say: "The neighbour called him a pyromaniac. Does that mean he will burn us alive? Is this schizophrenia? Should we lock him up? He sneaks matches and laughs when he sees fire videos online. What do we do tonight?" [1][2]
Marking domains
- Triad explained without jargon overload
- Pyromania rarity / poor fit for most youth fireplay stated
- Neither false reassurance nor catastrophic certainty
- Concrete tonight safety plan (means, supervision, escalation)
- Broader developmental/offending pathway and help options named
- Empathy, structure, check-back; no invented statutes [1][2][3]
Reveal assessor key
Open. Validate fear; purpose: accurate words and a practical plan tonight. [3]
Labels. Deliberate fire-starting is firesetting behaviour. Arson is a legal charge if the justice system is involved — that is separate. Pyromania is a rare psychiatric diagnosis with strict rules; most young people who set fires do not have it, and adult arson series also find true pyromania uncommon.[1][4]
Risk frame. This is serious because fire is dangerous, and repeated firesetting needs active management. It does not mean he will "definitely" destroy the home or that he has schizophrenia. Psychosis can link to arson in adults in research, but that is not the default explanation for adolescent fireplay — we still screen for mental health problems.[2][5]
Tonight's plan. Remove and lock matches/lighters/accelerants; increase supervision; limit fire-content videos if fueling interest; agree who to call if he threatens to burn something; arrange fire-safety education / youth firesetting programme pathways where available; mental health follow-up for mood, ADHD, conduct, substances, trauma. [2][3]
Close. Summarise; check understanding; written safety steps; follow-up time. [2]
Communication phrases (high-yield)
- "Firesetting is the behaviour; pyromania is a rare diagnosis — they are not the same."
- "We take fire seriously without assuming he is destined to burn the house down."
- "Youth firesetting can mark wider problems over time — early help is the point."
- "Tonight we remove means and increase supervision; that is treatment-relevant safety."
- "I will not invent legal section numbers; if police are already involved, we coordinate with them."
