Station brief
Format. Communication station, approximately 7–10 minutes active time after reading. You are the psychiatry registrar in outpatient clinic. [1]
Candidate instructions. The patient has major depression after forced redundancy. Explain what IPT is in plain language, introduce the idea that depression is an illness linked to life roles/relationships, propose a primary role transition focus, outline roughly how many sessions and what “middle work” looks like, and answer whether they must stop their SSRI. Check understanding; avoid promising cure; collaborative tone. [1][2]
Candidate scenario
Your patient is 47, made redundant 3 months ago after 15 years in the same firm. They feel worthless, argue with their spouse about money, and avoid friends who “still have jobs.” PHQ-9 is 16. They started sertraline 100 mg 6 weeks ago with partial benefit. They have heard of CBT worksheets and want something “more about my life situation.” No active suicidal plan; intermittent passive death wish only. No mania history. [2][3]
Marking domains
- Warmth, collaboration, jargon control
- Accurate plain-language IPT definition (time-limited; mood ↔ relationships; medical model)
- Names sick role appropriately (temporary, recovery-oriented)
- Selects role transition as primary focus; may note secondary role dispute with spouse
- Mentions inventory, one focus, approximate session course, termination
- Medication: combined care acceptable; no unsupervised stop
- Realistic hope; checks understanding [1][2][5]
Reveal assessor key
Open. Role; ask what they already understand by “therapy”; permission to sketch how IPT works. [1]
Explain IPT. Time-limited talking treatment that treats depression as a real illness and looks at how recent life changes and relationships keep mood low — then works on that focus for a set number of weeks, not endless chat and not mainly worksheets. [1][2]
Focus. Losing a long-held job is a major role transition (identity, routine, income, status). We may also work communication with your spouse about money stress, but we pick a primary focus so sessions stay specific. Inventory maps important people and recent events. [1]
Course. Often about three months of weekly sessions: first clarify diagnosis and focus; middle work on the transition (mourn old role, build new routines/supports, communication practice); ending reviews skills and warning signs. [1]
Medication. Sertraline can continue; tablets and IPT often work together. Do not stop medication on your own — review with your prescriber. Evidence supports IPT as an effective psychological treatment for depression and allows combined pathways. [2][3][5]
Close. Check understanding; invite questions; safety-net if mood or risk worsens between sessions. [4]
