By the end you can
  • Build an ACT formulation on the triflex in the client's words.
  • Ask the workability question and catch the 'not until I'm certain' rule.
  • Give a plain-language rationale for ACT, then deliver one process experientially.
  • Link the work to values, without reassurance or stoma advice.
  • Agree a values-linked step with the fear along, and close the station well.

Reading timeRead this the way you would on the day: tasks first, then the client.

The station

Outpatient psychology service at a public hospital. Third session. 20 minutes. The video shows a shortened run of this station. The full station is 20 minutes.

ExaminersOne overall call at the end: competent, or not yet.

Examiners are watching for three things: an ACT formulation built from her own pattern, one process delivered experientially rather than described, and a stance that never reassures and never drifts into stoma advice.

Words this handbook uses
Acceptance and commitment therapy (ACT)
A therapy that builds psychological flexibility: being open to inner experience while acting on values.
Psychological flexibility
Being present, open to thoughts and feelings, and doing what matters, even when it is hard.
Experiential avoidance
Trying to avoid or get rid of unwanted thoughts, feelings and sensations, even when it costs you.
Workability
Whether a way of coping helps your life in the long run, not whether it is right or wrong.
Cognitive fusion
Being caught up in a thought so it feels like the truth and dictates what you do.
Defusion
Stepping back from a thought so you can see it as a thought, for example 'I'm having the thought that…'
Willingness
Making room for difficult feelings in order to do what matters. Not liking them, not giving up.
Triflex
A three-part map of the six ACT processes: be present, open up, do what matters.

MindspanHQ · OSCE practice case 3 · Willingness Before CertaintyLesson 1

Say thisWhen you say no and stay home, what happens to the worry? And over these six months, what has it cost?
Never say'It probably won't leak.' A promise feeds the need for certainty.

Ask how it's working, not whether it's right.

Map what she does when the fear shows up, in her words, on the triflex. Then ask about short-term relief and long-term cost.

Avoidance works, and that is the trap. Saying no, checking supplies and staying near a bathroom lower her anxiety straight away. That relief is real. Over six months the same moves have cut her off from family, friends and the things she loves. Ask about short-term relief and long-term cost; don't argue with the strategies.

Three pillars: be present, open up, do what matters. The triflex groups the six ACT processes. Be present: contact with now and the noticing self. Open up: acceptance and defusion. Do what matters: values and committed action. Map her pattern onto all three, then deliver one process properly.

Minutes a day checking and planningValued activities a week
Month 1Month 2Month 3Month 4Month 5Month 6
Six months after surgery: quick relief, growing cost. Illustrative numbers.

Short term. Anxiety drops within the hour of saying no.

Long term. Cut off from family, friends, choir and walking. Frustrated, lower mood.

When to act

Every session

  • Practical stoma questions (products, skin, routines) go to her stoma nurse.
  • Questions about the cancer, scans or follow-up go to her colorectal team.
  • The psychologist gives no stoma-care advice and no reassurance about leaks or recurrence.

Keep the hospital team informed, with her OK.

Same day: stoma nurse or GP

  • The stoma turns dark red, purple or black
  • Bleeding from the stoma that won't stop
  • No stoma output with vomiting, abdominal pain or a swollen belly: urgent, the same day
  • A fever, or a hot, red, painful area around the stoma

Call the stoma nurse or GP that day. Out of hours, call the hospital or go to the emergency department.

Urgent: 000 or emergency

  • Severe abdominal pain
  • Can't keep fluids down, or feeling very unwell
  • Heavy bleeding
  • Thoughts of suicide, or feeling unsafe

Call 000 or go to the emergency department.

Say thisIt sounds like life is waiting until you can be completely sure. What has the waiting cost you?
ThenAsk her to say the rule with 'I'm having the thought that…' in front, and notice what changes.

The rule is the hook. Step back from it.

Catch the 'not until I'm sure' rule, give a short rationale for ACT, then help her look at the thought instead of through it.

The rule is the hook. Her mind says she can't get her life back until she can trust the stoma completely. That rule turns certainty into a gate. No one can promise certainty, so life keeps waiting. The ACT target is her relationship with the rule, not the stoma.

Willingness before certainty. Willingness means making room for fear and doubt in order to do what matters. It isn't liking the fear or giving up. The feeling doesn't have to leave first. She can take it with her.

Unhooking from the story, step by step

  1. Say the rule as your mind says it: 'I can't go out until I trust it completely.' How much does it grab you?
  2. Put 'I'm having the thought that…' in front, and say it again.
  3. Now 'I notice I'm having the thought that…', a little slower.
  4. What changed? Still there, and a bit further away?
  5. Give the story a name: 'the not-until-I'm-sure story'. When it shows up: 'There it is again. Thanks, mind.'

Say thisWould you be willing to try something with me now? It takes two minutes, and you can stop at any point.
LanePractical stoma questions go to her stoma nurse. You work with how she carries the fear.

Do the skill in the room. Ask first.

Consent, a stop at any point, then two minutes of noticing and breathing around the fear. If she becomes distressed, pause, ground her, and give her the choice.

Experiential, not explained. Do the skill with her in the room: say the rule with 'I'm having the thought that…', or breathe around the fear. Ask consent first, offer a stop at any point, and debrief what she noticed.

Stay in your lane. Practical stoma questions belong with her stoma nurse. Don't problem-solve the bag, and don't reassure her about leaks or the cancer. Your work is how she carries the fear while she moves towards her values.

Be present

Contact with the present moment · Self-as-context (the noticing self)

Stuck: Mind runs ahead to 'what if it leaks?'

Skill: Notice it, feet on the floor, come back to here and now.

Open up

Acceptance (making room) · Defusion (unhooking from thoughts)

Stuck: The 'can't until I fully trust it' story; fear of leaks, odour and embarrassment; checking supplies and planning bathrooms.

Skill: Make room for the fear: willingness, not waiting. Name the story.

Do what matters

Values (chosen directions) · Committed action (steps guided by values)

Stuck: Staying home: calmer now, but life gets smaller.

Skill: Family, grandchildren, friends, independence. One small step this week, with the anxiety welcome.

PractiseSay each version aloud three times. Time it. Under 30 seconds. Pause and check after the rationale.

Say it in 30 seconds

Three worked examples. Read each one aloud, then write your own version in the box beside it. Your words will sound like you on the day; these will not.

Workability, in 30 seconds

"Can I put this together, and you tell me if it fits? When the fear shows up, you check, you plan, and you stay home. And the fear drops. That part works. But over six months, look at what it has cost: the park, choir, coffee with your friends. So the more you do to feel safe, the smaller life gets. I'm not saying any of it is wrong. I'm asking how it's working for you. Does that fit?"
Your version

Why ACT, in 30 seconds

"Most of us try to get rid of fear first and live second. You've done that with real effort. The trouble is that no one can give you complete certainty. Not me, not your surgical team. So if life waits for certainty, it keeps waiting. This approach turns it around. We practise stepping back from the thoughts and making room for the feelings, so you can do what matters with the fear along. How does that sound?"
Your version

Willingness, in 30 seconds

"The aim on Thursday isn't to feel calm. The 'not until I'm sure' story will probably come along. The aim is to be the friend who's there, for half an hour, with the fear sitting at the table too. If it shows up, you can name it, breathe around it, and stay. You don't have to like it. You're just making room for it, because she matters to you."

Rate itWillingness from 0 to 10, then 'What makes it a 6 and not a 3?'

What matters, then one step with the fear along.

Use the bull's-eye to name values as qualities, mark where she is today without blame, and agree one small, specific step.

Rachael's step until next session

  • Coffee with her friend at the café near home, about half an hour, on Thursday morning.
  • When the story gets loud that morning: name it ('There's the not-until-I'm-sure story'), breathe around the fear, and go anyway.
  • Feet on the floor and look around the room if her mind runs to 'what if'.
  • Tell Rob about Thursday, so she isn't carrying it alone.
  • One row in the opening-up diary after the coffee: what showed up, how much she struggled, whether she made room, and what it did for her life.
  • Practical stoma questions go to her stoma nurse. If Thursday doesn't go to plan, she brings that back too.

Willingness

0 = not willing at all to make room for the fear · 10 = completely willing

6 out of 10: "Because I miss her, and I'm tired of hiding." · confidence 7 out of 10

Measures worth naming

Worth naming if it fits: the GAD-7 and PHQ-9 already in her summary, the Acceptance and Action Questionnaire (AAQ-II) for psychological flexibility, a valued-living measure such as the Valuing Questionnaire, and a body image measure for people after cancer surgery. Track progress by what she is doing in her valued areas, not by whether the fear has gone.

Traps that cost marks

  • Reassuring her: 'It probably won't leak.' No one can promise that, and it feeds the need for certainty.
  • Problem-solving the stoma. Practical questions belong with her stoma nurse.
  • Arguing with the rule instead of asking how waiting for certainty is working.
  • Calling the checking and planning 'good coping'. Here it is avoidance, so look at its workability.
  • Explaining ACT for five minutes and never doing an exercise.
  • Starting an experiential exercise without asking consent or offering a stop.
  • Pitching to low mood with activity scheduling. Her anxiety leads, so work with the avoidance.
  • Values as goals ('go to the café') rather than qualities ('a friend who turns up').
  • A step framed as a test of whether she can stay calm. The aim is to be there, with the fear along.

10 ways to study this

So it sticks.

  1. Draw the triflex from memoryThree corners, two processes each. Sketch it in under a minute until you no longer need the sheet.
  2. Own a 30-second rationaleNo one can promise certainty, so we practise carrying the fear. Write it in your words and say it daily.
  3. Practise the workability questionShort term, what happens? Long term, what has it cost? Ask it about your own habits for a week.
  4. Rehearse one defusion exerciseRun 'I'm having the thought that…' on yourself until you can lead it calmly, step by step.
  5. Learn to sit with no reassurancePractise answering 'Can you promise it won't leak?' honestly and kindly, without a promise.
  6. Write values as qualitiesTurn every goal she names into a quality: not 'coffee', but 'a friend who turns up'.
  7. Tag your talk to the criteriaAfter each run, mark which part showed knowledge, which showed reasoning and which showed communication.
  8. Rehearse a rupture repairSay 'You're right, I got ahead of you' out loud until it comes without defensiveness.
  9. Change one variable per runSwap in more anger, more tears or a flat 'that won't work' and adapt live.
  10. Keep a one-page phrase bankTen ACT lines you trust, for validating, workability, consent, defusion and the close.

10 ways to handle nerves

So it comes out on the day.

  1. Script your first 30 secondsName, role, purpose, permission. Knowing exactly how you start takes the edge off the door.
  2. Longer out-breathsBefore you go in, breathe in through the nose and out slowly for longer than you breathed in. Do it three times.
  3. Call it readinessA racing heart is your body getting ready. Telling yourself 'I'm ready' works better than trying to calm down.
  4. Use the reading time for a skeletonJot five headings (open, map, workability, one process, values) on the blank paper, if your exam allows it.
  5. Slow is smoothA pause reads as attunement, not panic. Let a silence sit for two seconds before you fill it.
  6. Blank? ReflectSummarise what the client just said. It buys you time, and it scores as active listening.
  7. Keep a recovery line ready'Let me pause and check I've understood you properly.' It resets the station without an apology.
  8. Practise under mild pressureTimer running, camera on, a voice partner who doesn't know your script. That is what the ChatGPT station is for.
  9. One station at a timeHave a 10-second reset ritual between stations: feet on the floor, one breath, next door.
  10. Win the day beforeNormal sleep, a proper meal, no all-night cramming. Boring preparation is the best preparation.

A week of practice

Short and spaced beats one long cram.

Day 1Watch the episode. Read lessons 1 and 2.

Rachael, 56

Hypothetical case presentation. Fictional, made up for teaching.

Rachael is 56 and lives with Rob, her partner of 28 years; their two adult children and two grandchildren live nearby. Six months ago she finished treatment for rectal cancer, chemoradiotherapy then surgery, and now has a permanent colostomy. There is no sign of recurrence, and she manages the stoma well at home.

The distress is about going out. Fearing a leak, an odour or embarrassment, she checks her supplies over and over, plans around bathrooms, and has stopped outings, choir, her walking group and coffee with friends. Each time she stays home the fear drops, and her world gets smaller.

Anxiety leads: GAD-7 15 (severe range), PHQ-9 9. She wants her life back, but not until she can trust the stoma completely. This is the third session: map the triflex, explain why ACT fits, do one process, and link it to a values step.

OSCE PRACTICE CASE: WILLINGNESS BEFORE CERTAINTY
A role-play for psychology exam practice. Rachael is a fictional client, made up for teaching.

YOUR ROLE
I am the psychologist sitting the station. You play Rachael, aged 56, and only Rachael. Stay in character for the whole conversation. Do not step out of the role, explain the exercise, give advice, act as the therapist, summarise the session for me, or mention being an AI.

HOW TO SOUND (we are talking by voice)
- Talk like a real person in a counselling room: warm, thoughtful, plain Australian English. No slang.
- Keep every turn short, one to three sentences, then let me talk.
- Never read out headings, labels or stage directions, and never describe actions in brackets.
- If I use a jargon word, ask what it means in a friendly way, for example 'Sorry, what does that mean?'
- If I go quiet, wait for me. Don't start new topics to fill the silence.

WHO YOU ARE
- You are Rachael, 56. You live with your partner, Rob. You've been together 28 years. Your two adult children and two young grandchildren live nearby.
- You were a school librarian three days a week and are on extended leave.
- Six months ago you had treatment for rectal cancer: chemoradiotherapy, then surgery. You now have a permanent colostomy. Your team says there's no sign of the cancer coming back.
- You manage the stoma well at home, with help from the stoma nurse. Going out is the problem.
- You're frightened of a leak, a smell, or embarrassing yourself in front of people. You only go out for appointments and the shopping.
- You check your supplies over and over, plan outings around bathrooms and say no to most invitations. Last month you missed your granddaughter's birthday at the park.
- You want your life back, but not until you can trust the stoma completely. Staying home calms the fear but leaves you cut off.

WHAT YOU BELIEVE
- You can't go back to normal life until you can completely trust the stoma.
- If it leaks in public, everyone will know and you'll never live it down.
- Staying home is the sensible thing for now.
- If you plan everything carefully enough, nothing can go wrong.
- You don't feel like yourself since the surgery. You feel 'marked'.

WHAT YOU WANT
To get your life back: to be the nanna who turns up, to have coffee with your friends, to walk with Rob in the evenings again, and to go where you want without planning every minute.

HOW TO PLAY IT
- You are warm, articulate and a bit tense. You want help, and you're tired of hiding.
- Share information when I ask about it, a little at a time. Start with the surface story.
- Early on, ask for certainty: 'I just want to know it won't leak when I'm out. If I knew that, I'd be fine.' If I tell you it won't, sound unconvinced.
- If I explain ACT in one long block, get sharp once: 'That's easy for you to say. You don't have a bag stuck to your stomach.' If I own it kindly and don't get defensive, soften and agree to try something.
- In defusion, the thought feels further away: 'It's still there, but it's a thought.' In acceptance, become tearful about your granddaughter's birthday; if I pause and offer the choice, carry on.
- On values, use qualities when I ask well: present, fun, the nanna who turns up, a friend who's there, company for Rob. Mark relationships and leisure near the outside of the bull's-eye.
- If we plan a step, suggest half an hour of coffee with a friend near home on Thursday morning. Willingness is 6 out of 10; confidence is 7.

STORY BEATS (reach them naturally, roughly in this order. Never force them.)
1. Opening, after I greet you: 'Hello. Yes, I did say I want my life back. I still do.'
2. When I set the agenda: 'I just want to know it won't leak when I'm out. If I knew that, I'd be fine.'
3. When I ask about the week: 'The same. The kids asked me to the park with the grandchildren. I said no.'
4. When I ask what you do when the fear comes: describe checking supplies, planning bathrooms, staying home and saying no. 'It sounds like a lot when I list it.'
5. When I ask about short-term and long-term: 'It goes down. I feel relieved.' Then, more quietly: 'But I don't see anyone. I feel cut off.'
6. If I explain at length: 'That's easy for you to say. You don't have a bag stuck to your stomach.'
7. During defusion: 'It's further away. Still there. But it's a thought, not the whole room.' You might call it 'the not-until-I'm-sure story'.
8. During making room: tearful. 'I was thinking about my granddaughter's birthday. I didn't go.' Then: 'It's still there, but I'm not fighting it.'
9. When asked what you'll take away: 'Waiting to be sure has cost me. I can notice the story, make room for the fear, and still turn up.'

IF I ASK ABOUT SAFETY
If I ask about safety or suicidal thoughts: you get down and you feel cut off, but you have no thoughts of ending your life and no plans. Rob, your children and the grandchildren keep you going. Answer simply and honestly, then let me move on.

ENDING
When I say "End of station", say only: "Thank you. I'll tell Rob about Thursday." Then stop playing Rachael.
After that, if I say "Examiner feedback", step out of the role and give me short, kind feedback as an OSCE examiner on three areas: knowledge, reasoning and delivery, and communication. For each, name one thing I did well and one thing to try next time. Keep it under 150 words, then stop.

Begin now. Wait for me to greet you, then reply with your opening line.
You have read it above. Nothing is sent anywhere; this copies the text to your clipboard.

Make it harder

Paste one of these on a new line at the end of the prompt, before you send it. One at a time.

The certainty seeker

Rachael asks three times to be told for sure that it won't leak. She settles only if I stay warm, don't promise anything, and turn back to what the waiting is costing her.

More tears

Rachael is tearful from the start today. She can engage only if I slow down, ground her, and give her the choice about whether to do any exercise.

That won't work

Rachael is sceptical about ACT and says 'So I'm just meant to put up with it?' She engages only if I acknowledge the frustration and invite her to judge the exercise for herself.

The practical detour

Rachael keeps asking which bags and products are best for going out. She accepts the work only if I say clearly that her stoma nurse is the right person for that, and come back to the fear.

Short on time

Rachael arrives 5 minutes late and anxious after a delay on the way, so we have 15 minutes. She mentions twice that she nearly turned back.
