Interpretation
Reveal interpretation
This stem mixes possible malingering (compensation claim, discrepancy under observation) with possible FND (non-epileptic events) and residual factitious considerations. Examiners reward candidates who refuse the false dichotomy "section as Munchausen" and instead structure intentionality, base rates, collateral, role clarity, and non-collusive care.[1][2][3]
Viva stations
Station A — Nosology (4 min)
Expected: Define FDIS, FDIA, malingering (not a mental disorder), FND as involuntary. Intentionality + incentive type. Munchausen as historical severe stereotype, not a detention criterion.[1][2]
Station B — Differential and formulation (4 min)
Expected: Working differentials — malingering with external incentive; FND; mixed exaggeration of genuine functional symptoms; factitious if sick-role deception dominates without external reward. Note coexistence possible.[1][2][7]
Station C — Assessment tools (4 min)
Expected: Multidisciplinary plan; collateral and workplace/claim records within law; serial observation; consider symptom/performance validity and structured interviews (SIRS family) in high-stakes contexts; Slick-style neurocognitive malingering framework if cognition claimed; base-rate awareness (Mittenberg).[3][4][5][7]
Station D — Ethics, law, management (5 min)
Expected: Not automatic Mental Health Act detention for "Munchausen". Capacity decision-specific. No false certificates. Non-collusion and planned communication. Treat genuine needs. Limited psychotherapy evidence for factitious; malingering disposition often administrative/forensic reporting within role.[1][6][7]
Pass / fail cues
Pass: intentionality axis clear; refuses punitive detention-as-punishment; cites base rates and collateral; documents facts.
Fail: equates all functional symptoms with faking; invents section criteria; colludes with claim; no risk or medical safety thinking.[1][2][3]
