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 anxiety and has been waiting to "feel normal" before returning to a valued activity. Explain what ACT is in plain language, introduce willingness versus struggle, link to one valued direction, set one small committed action, and answer whether they must stop their SSRI. Check understanding; avoid promising cure; collaborative tone. [1][3]
Candidate scenario
Your patient is 33, with 10 months of generalised anxiety and panic symptoms. They stopped choir practice (previously a core part of identity and social support) because "I can't risk a panic attack in front of people." They spend evenings analysing body sensations. Sertraline 75 mg for 7 weeks has given partial benefit. GAD-7 is 15. No active suicidal plan; occasional passive death wish only. They have tried thought-challenging worksheets and felt "arguing with my brain makes it worse." [2][4]
Marking domains
- Warmth, collaboration, jargon control
- Accurate plain-language ACT aim (flexibility; live by values even with discomfort)
- Names control agenda / struggle cost without shaming
- Introduces willingness/defusion idea without requiring full hexaflex lecture
- Co-creates one graded committed action tied to choir/values
- Medication: combined care acceptable; no unsupervised stop
- Realistic hope; checks understanding; safety-net [1][3]
Reveal assessor key
Open. Role; ask what they already understand by "acceptance therapy"; permission to sketch a different way of relating to anxiety. [1]
Explain ACT. A talking treatment that helps you get better at living the life you care about — relationships, music, work — even when anxiety shows up, instead of waiting until every uncomfortable thought or feeling is gone. We practise skills for noticing thoughts as thoughts, making room for sensations, and taking small steps toward what matters. [1][3]
Control agenda. Spending evenings monitoring the body and avoiding choir may calm you briefly but costs connection and identity — that trade-off is what we map together.[2]
Skills preview. Instead of only arguing with thoughts on paper, we may practice phrases like "I am noticing the thought that I will panic" and willingness to have a fluttery chest while still doing a tiny valued step. [1]
Committed action. Example: attend the last 15 minutes of choir rehearsal this Thursday, sit near the door, use a pre-agreed willingness cue, text a friend afterwards — grade further down if needed. Review next session. [1]
Medication. Sertraline can continue; tablets and ACT often work together. Do not stop medication on your own. Evidence supports ACT as an effective psychological approach for many clinical problems including anxiety-related presentations in broader research syntheses, and comparative work with CBT exists. [3][4]
Close. Check understanding; invite questions; safety-net if mood, panic, or risk worsens between sessions; mention we may track both symptoms and how stuck/flexible life feels (process measures exist in research/clinical use such as AAQ-II, explained simply if asked). [5]
