Target exams
Station brief
Format. Communication station, approximately 7–10 minutes active time after reading. You are the psychiatry registrar in the outpatient clinic. [3]
Candidate instructions. Explain adult separation anxiety disorder in plain language (including that it can start in adulthood), how it differs from pure unexpected panic, the rationale for graded practice being alone and reducing checking calls, why daily long-term diazepam is not recommended as the main plan, optional SSRI discussion at a high level, expected hard work and benefits, and safety-netting for mood. Check understanding and invite questions. The examiner plays the patient. [1][2][3]
Candidate scenario
Your patient meets criteria for adult separation anxiety disorder with partner as attachment figure. She has ED attendances when he is away, nightmares about his death, and occupational impairment from travel refusal. She requests "diazepam every night forever" and fears exposure means "locking me in a house alone cold turkey." You plan collaborative hierarchy work, checking response prevention, and discussion of SSRI if severity warrants. [1][3]
Marking domains
- Empathy, structure and agenda-setting
- Accurate plain-language explanation of adult SeAD and DSM-5 lifespan recognition
- Clear distinction from pure panic without dismissing her ED experiences
- Exposure and accommodation/checking plan explained without jargon overload
- Benzodiazepine stewardship without shaming
- Optional SSRI framed with monitoring language
- Checks understanding and safety-nets mood/risk [1][2][3]
Reveal assessor key
Open and agenda-set. Name time; ask her main fears (being abandoned in treatment, addiction, forced isolation). [3]
Explain diagnosis. "Separation anxiety disorder means a strong, lasting fear about being apart from someone you are closely attached to — for you, your partner — with checking, sleep problems when he is away, and real impact on life. It can start in adulthood; it is not only a children's label." [1][2]
Relate to panic. "The frightening surges make sense when you are alone and convinced something terrible will happen to him or that you cannot cope. That pattern fits separation anxiety better than only random panic, though we still take the physical fear seriously." [1]
Explain exposure. "The most effective approach is carefully planned practice being alone and handling his time away in steps you help design, while cutting back on habits like constant location-checking that keep the fear stuck. We do not dump you into a week alone on day one." [3]
Diazepam discussion. "A tablet every night long-term is not the best main treatment — it can cause dependence and may stop you learning that you can cope. Skills and graded practice are the plan; if medicine is needed we usually consider an SSRI with monitoring rather than chronic diazepam." [3][4]
Close. Summarise, teach-back, written step plan, crisis contacts if mood worsens, book therapy start, GP liaison. [3]
