Target exams
Station brief
Format. Communication station, approximately 7–10 minutes active time after reading. You are the psychiatry registrar in the outpatient/C-L clinic. [2]
Candidate instructions. Explain SSD in plain language without dualism, outline a collaborative stepped plan (scheduled GP care, CBT, treat depression), address the request for another immediate whole-body scan with red-flag safety-netting, and check understanding. The examiner plays the patient. [1][2]
Candidate scenario
Your patient has multi-system symptoms, high health anxiety behaviours (checking, ED visits), moderate depression, and extensive prior negative investigations without progressive disease markers. You plan: validation; SSD working diagnosis; GP-coordinated scheduled reviews; CBT for health anxiety/symptom focus; discuss an SSRI such as sertraline starting at 25–50 mg orally daily with monitoring if depression/anxiety treatment is agreed; agree symptoms that should prompt urgent medical review. They believe another scan today is the only path to safety. [1][3][5]
Marking domains
- Empathy, structure and agenda-setting
- Accurate plain-language both–and model (symptoms real; attention/threat loops amplify disability)
- Clear explanation that SSD is not “faking” and does not require medically unexplained as the sole logic
- Stepped plan: scheduled visits, CBT rationale, mood treatment discussion
- Handling scan request: limits of unfocused testing + red-flag re-open criteria
- Safety-net for suicide/mood worsening and medical red flags
- Checks understanding / teach-back [2][3][4]
Reveal assessor key
Open and agenda-set. Name time; ask main fears (being called fake; missing cancer; losing access to care). [2]
Explain SSD. “SSD is a recognised diagnosis when bodily symptoms are distressing and the way the mind and body respond — worry, checking, emergency visits — takes over life. Your symptoms are real. It does not mean you invented them or that doctors will never reassess if something new appears.” [1][2]
Both–and model. Threat and attention systems can keep symptoms loud; reducing checking and building function helps even when serious disease is not progressive on current evidence. [3]
Care plan. Regular GP appointments (not only crisis ED); one coordinating clinician; CBT that targets health fears and behaviours (evidence from CBT trials including medical-clinic health-anxiety CBT); treat depression with psychological care and, if agreed, an SSRI with clear start-dose discussion and side-effect monitoring. [3][4][5]
Scans. Another whole-body scan today without a new clinical question can create false alarms and anxiety without improving safety. We keep a written list of red flags (e.g. progressive night pain, neurological change, unintentional weight loss, new organ symptoms) that reopen assessment. [2]
Close. Teach-back; written plan; crisis contacts; mood safety-net. [2]
Actor prompts (optional)
Common challenges: “So you think I am crazy?”; “If you refuse the scan and I have cancer, it is your fault”; “My partner says doctors never listen”; “I only feel safe in ED.” Respond with validation, both–and explanation, and red-flag safety-netting rather than dualism or collusion with unfocused imaging.[1][2]
Post-station notes
Examiners reward non-defensive validation, accurate nosology, and a concrete anti-iatrogenic plan. Fail modes: dualism (“all in your head”), colluding with endless unfocused imaging, or abandoning medical safety-netting.[2][5]
