Station brief
Format. Communication station, approximately 7–10 minutes active time. You are the psychiatry registrar in the medical clinic.[2]
Candidate instructions. Acknowledge anger and fear of being called a faker; explain illness behaviour language without pejorative dualism; validate symptoms; outline a collaborative plan (scheduled care, re-investigation thresholds, CBT for health anxiety, mood support); engage partner without colluding with endless scopes; safety-net red flags and low mood.[1][2][3]
Candidate scenario
The patient feels dismissed by the phrase “abnormal illness behaviour.” Your task is honest, non-punitive communication that still sets limits on unfocused investigation and offers effective care.[1][2]
Actor notes (examiner plays patient / partner)
- Patient: angry, ashamed, fears “crazy” or “faker” label; catastrophises about missed cancer.
- Softens if candidate validates symptoms and offers a concrete plan.
- Partner: pushes for more tests; if candidate only colludes, partner escalates demands — mark down for collusion without thresholds.
- Admits low mood when asked gently; no active suicide plan. Cultural and stigma sensitivity expected when explaining bodily distress pathways.[5]
Domains assessed
- Empathy and repair after pejorative labelling.[2]
- Accurate non-dualistic explanation of illness behaviour / AIB.[1][2]
- Shared plan: scheduled reviews, investigation thresholds, functional goals.[2]
- Offer of CBT-style health-anxiety care and mood treatment pathway.[3][4]
- Partner work and safety-netting (red flags, crisis contacts).[2]
Model communication points
Reveal example phrases
- "I can see how being told this is ‘abnormal illness behaviour’ felt like being accused of faking. That is not what I mean, and it is not how I will work with you."[1]
- "Your symptoms and distress are real. Sometimes the body’s alarm system and the way we check and worry can keep suffering high even when serious disease has been carefully looked for."[2][3]
- "We will agree clear reasons to re-investigate if new red flags appear. Right now another scope without a new indication may increase fear without improving safety."[2]
- "A structured psychological approach for health anxiety has good trial evidence, including in medical clinics, and we should also treat the low mood you describe."[3][4]
- "To your partner: support is vital, and permanent invalidism can make recovery harder. Let’s set shared goals around activity and scheduled reviews rather than only emergency visits."[2]
- "If pain, bleeding, weight loss, or other new danger signs appear, seek urgent care. If mood worsens or you feel unsafe, here is how to get help today."[2]
Examiner scoring cues
Pass: validates, explains without dualism, sets investigation limits, offers CBT/mood plan, partners productively, safety-nets.
Borderline: accurate but cold or overly technical.
Fail: colludes with endless scopes; humiliates; implies faking; no safety-net; forces psychological confession as condition of care.[1][2][3]
