Cognitive defusion exercises help teens notice a thought without automatically treating it as an instruction. In ACT, the aim is a more flexible response: a thought can remain present while the young person chooses an action that matters to them. The aim is not to erase thoughts, force positive thinking or prove a concern is false.
Below are ten ways therapists can practise this skill, with materials, exact prompts, examples and adaptations. Choose one suitable exercise and try it collaboratively; this is a menu, not a ten-exercise session plan.
What is cognitive defusion, and how do you explain it to a teen?
A simple explanation is: “Your mind gives you words and pictures. Sometimes they are useful information; sometimes following them automatically gets in the way. We can practise noticing what your mind says and choosing what to do next.”
The ACT process model described by ACBS focuses defusion on the function of thoughts rather than requiring their content or frequency to change. A thought feeling less intense may occur, but it is not the test of whether the practice was useful.
Start with an ordinary, manageable example the teen agrees to explore, or a fictional character. Ask what they want to do differently in that situation. Check whether they need information, protection, practical support or a different intervention before choosing defusion. Bullying, discrimination and unsafe circumstances are not simply thinking problems.
Opening invitation: “Would you like to try noticing this thought in a different way, then see whether it gives you more choice? You can change the wording or stop.”
A teen who dislikes playful metaphors can use plain language. Do not require closed eyes, a silly voice, reading personal thoughts aloud or appearing relaxed. The exercises below are educational ACT-informed practice suggestions; they are not a stand-alone treatment protocol.
For the broader model, see ACT worksheets and the six core processes. If you are deciding between evidence review, problem-solving and defusion, our guide to what to do after identifying a cognitive distortion explains those different tasks.

1. Add a noticing phrase
Materials: None, or one scrap of paper. Skill: describing thinking rather than automatically responding to its content.
- Ask for a mild thought associated with an agreed task, such as “I’ll get this wrong.” Do not ask the teen to repeat their most painful self-criticism.
- Invite them to say or silently read it once, then describe the experience: “I notice the thought that I’ll get this wrong.” Let them choose more natural wording, such as “My brain is giving me the wrong-answer prediction.”
- Ask: “With those words still here, what would you like to do?” Try one small step in the chosen task.
Example: A teen notices “I’ll get this wrong” while choosing to ask what an instruction means.
Debrief: “Did that wording give you any room to choose, or did it feel like another demand?”
Adaptation: Use silent noticing or let the therapist model a fictional thought. Do not repeat the phrase until it sounds believable or reassuring; the practice is not a verbal ritual for feeling safe.
2. Brain notifications: a message is not a command
Materials: Two small scraps labelled “Message” and “My response.” No phone is needed. Skill: separating a thought arriving from what the teen chooses next.
- Explain: “A notification can arrive without deciding what you do. Let’s borrow that idea for a thought.” Write a familiar prediction on the Message scrap.
- Ask what response the message usually prompts. Write an alternative the teen chooses on the second scrap; keep it behavioural rather than a positive replacement sentence.
- Place both scraps where they can be seen and rehearse the response. The message stays visible; the teen is not asked to delete it.
Example: Message: “My drawing will look bad.” Response: “Sketch one outline because making things interests me.”
Debrief: “What changed when the message and your response were separate?”
Adaptation: Use two spoken sentences or icons if writing is tiring. Check that the notification metaphor feels relevant. It is not advice to ignore useful information or genuine danger.
3. Name a recurring story without judging it
Materials: A page with room for a title and two situations. Skill: recognising a repeated verbal pattern.
- Choose two recent, manageable situations where similar thoughts appeared. Write the teen's own words rather than assigning a cognitive-distortion label.
- Invite a neutral title: “What would you call this recurring storyline?” Let the teen reject the idea or choose a plain label.
- Revisit one situation and ask: “If this storyline appears again, what could you notice and what response would you want available?”
Example: “The not-good-enough story” appears before submitting a drawing and before trying a new hobby. Noticing the title can accompany choosing to show a draft to a trusted person.
Debrief: “Does the title help you recognise the pattern, or does it feel dismissive?”
Adaptation: Use fictional scenes or a neutral phrase such as “comparison thoughts.” Do not turn the label into a fixed identity or ask the teen to joke about something painful.
4. The commentary radio
Materials: None; a simple doodle of a radio is optional. Skill: noticing mental commentary alongside activity.
- Introduce the metaphor: “Imagine your mind has a commentary channel. What does it say during this task?” Choose a mild, agreed example.
- Invite the teen to describe one line as commentary in their ordinary voice, or let you model a fictional line. There is no need for imitation or comedy.
- Choose a brief, neutral task, such as arranging drawing materials. Notice any commentary and return attention to the task without trying to silence the station.
Example: The commentary says “This is going to be awkward” while the teen rehearses the first sentence of a conversation.
Debrief: “Could you hear the commentary and still decide where to put your attention?”
Adaptation: Keep everything silent if speaking would feel embarrassing. Do not increase volume or use a voice the teen experiences as mocking. If the metaphor does not fit, return to plain noticing.
5. Same words, different typography
Materials: Paper and a pen; colours are optional. Skill: noticing words as visible language while keeping their content unchanged.
- Write one mild thought in the teen's usual handwriting.
- Invite a second version using spaced letters, a different size or a simple border. Keep the same words; do not replace them with an affirmation.
- Look at both versions and ask: “What do you notice about the marks, the meaning and the urge to respond?” Connect the observation to an agreed next action.
Example: “I have to do it perfectly” is written normally and then as spaced letters. The teen can notice the rule as language while choosing to make a rough first draft.
Debrief: “Did changing the presentation help you notice the words differently?” It is equally useful to learn that it did not fit.
Adaptation: Use a neutral fictional phrase if personal writing is too exposing. No drawing skill or colourful output is required. Stop if rewriting becomes repetitive checking or a way to remove the thought.
6. Leaves on a stream: observe without clearing the water
Materials: None for imagery; a drawn stream and small paper leaves are optional. Skill: observing thoughts without pursuing or suppressing each one.
- Offer the familiar ACT imagery exercise in plain language: “If imagining a stream works for you, picture a thought written on a leaf. You do not have to make the leaf move or disappear.” Eyes may stay open.
- Invite a short practice, noticing a thought, placing its words on an imagined leaf and noticing what appears next. If the mind starts commenting on the exercise, that can be noticed too.
- End the practice together and return attention to the room and the agreed task. A leaf that stays put does not mean the teen failed.
Example: The thought “I’m doing this wrong” becomes something to notice during the practice rather than a reason to restart it.
Debrief: “Were you observing, or working hard to make the thoughts leave?”
Adaptation: A teen who does not visualise can look at written words on a paper leaf without moving it. No sensory immersion is necessary. Stop or change format if imagery increases distress or disorientation.
;7. Passengers on the bus: choose a direction
Materials: A simple bus outline and scraps, or a spoken version. Skill: linking defusion with values and action.
- Ask the teen to choose an ordinary direction that matters, such as creating, learning or spending time with a suitable friend. In this familiar ACT metaphor, that is where the bus is headed.
- Write one or two thoughts on passenger scraps. Ask what they say when the teen starts heading that way. They can remain on the page without controlling every decision.
- Choose one feasible “next stop” and rehearse it. Ask what support or adjustment is needed before trying it outside the session.
Example: The teen values creativity. A passenger says “Everyone else is better.” The next stop is spending a short, agreed time experimenting with a drawing.
Debrief: “Were you choosing a direction, or getting stuck in an argument with the passenger?”
Adaptation: Use a journey or playlist metaphor the teen prefers. Do not imply they have complete control over circumstances or should drive through danger. Protection and access needs are part of the route.

8. Same thought, different context
Materials: Two fictional character descriptions. Skill: exploring how context affects the influence of words.
- Create two characters encountering the same mild thought: “I might make a mistake.” One is trying an enjoyable craft; the other is completing an ordinary first draft.
- Ask: “What might each character do after hearing those words?” List several responses rather than choosing the supposedly correct one.
- Ask whether the teen notices a difference between the sentence itself and the circumstances or rules surrounding it. Apply that observation to a small situation they choose.
Example: The same sentence may be background commentary during a hobby but feel like a stop instruction before submitting a draft. The teen explores a response that makes room for learning.
Debrief: “What gave those words more or less influence in each situation?”
Adaptation: Use a favourite fictional character or speak through the scenarios. This is perspective practice, not a demand to treat all mistakes as harmless or to disprove a concern.
9. Forecast the thought before a situation
Materials: A small card with “Likely thought” and “Chosen response.” Skill: recognising a familiar thought when it arrives, rather than being surprised into following it.
- Choose an ordinary upcoming situation that is already part of the teen's plan. Ask: “Based on past experience, what might your mind say?”
- Write one likely thought and agree how the teen might notice it. Then choose one feasible response linked to their own aim.
- Rehearse the moment once. The thought does not have to appear exactly as predicted; the card is a reminder, not a checklist to monitor constantly.
Example: Before a familiar art class, the teen expects “Mine won’t be as good.” Their chosen response is to notice the comparison and begin their own first line.
Debrief: “Did expecting the thought help you recognise it without making it the main task?”
Adaptation: Use one spoken reminder instead of a card. Keep preparation brief if planning feeds rumination. Do not prescribe an exposure task or assume the teen's concern lacks a real-world basis.
10. Rehearse a choice with the thought present
Materials: One thought scrap, or a spoken reminder, and an agreed role-play. Skill: transferring noticing into behaviour.
- Choose an ordinary response the teen wants to practise, such as asking for clarification. Put a relevant thought on the table if seeing it is helpful.
- Ask: “Can these words be here while you try the sentence you chose?” Role-play the brief exchange with the teen's permission.
- Review what happened. Practise a smaller or differently supported version if needed; there is no requirement to repeat until anxiety falls.
Example: “They’ll think I should know already” sits on a scrap while the teen practises saying, “Could you explain the first part again?”
Debrief: “What helped you choose the response? What got in the way? What support would matter in the real situation?”
Adaptation: The teen can observe you model a fictional exchange, point to a sentence or skip role-play. A practice that becomes overwhelming calls for a change in the plan, not a test of perseverance.
How to adapt defusion exercises for groups and telehealth
Groups: Start with a fictional thought, such as “If I ask a question, I’ll look silly.” Demonstrate two formats and invite each member to choose, observe or pass. Discuss the difference between a thought and an instruction without collecting personal disclosures or voting on whose thought is true. Members can use different formats; no one has to perform a voice or show written material.
Telehealth: Read prompts aloud, use the client's own paper or an agreed private shared screen. Confirm privacy before writing personal details. Avoid recording sensitive thoughts on tools the teen does not control. A spoken example is enough.
Access: Offer pointing, short phrases, icons and breaks. Ask which language, sensory format and pace fits. Adaptation is not a lesser version of the exercise.
How to review defusion and plan between-session practice
Review the function of the practice. Ask: “What did you notice? Did it open any choice? What action did you take or decide against? What would make this more workable?” A thought that remains strong is not proof of failure.
If the teen wants practice between sessions, agree one ordinary cue and one format already tried together. For example: when comparison shows up during an existing hobby, notice the phrase and choose a next step. Agree how to review it; do not prescribe a quota of thoughts, daily disclosure or a requirement to feel calm.
A simple optional review has four prompts: situation, thought noticed, response chosen, and what helped or needs adjustment. Do not turn the record into constant self-monitoring. If a phrase, card or imagery practice becomes reassurance, neutralising or checking, revisit its function within the treatment plan, particularly in OCD work.

Cognitive defusion exercises for teens: common questions
What is a simple cognitive defusion exercise for a teen?
Invite the teen to describe a manageable thought with wording such as “I notice the thought that…” and then choose a small response that matters to them. Keep the wording natural and assess whether it helps choice, not whether it removes the thought.
Is cognitive defusion the same as challenging a thought?
No. Defusion explores how a thought influences behaviour. Cognitive restructuring may examine evidence and alternative meanings. The task depends on formulation and context; neither requires dismissing a realistic problem.
Do teens have to use silly voices or visualisation?
No. Plain noticing, paper prompts and quiet rehearsal are options. A playful format is useful only when the teen agrees it fits.
What if the thought is true?
A thought can contain accurate information and still be experienced as an automatic instruction. Address real needs and consequences while exploring the response. Defusion is not a method for denying facts.
Can defusion be used in OCD treatment?
It may support an individual treatment plan, but it is not a replacement for appropriate OCD care or ERP. Check whether the exercise helps flexible responding or has become a ritual for certainty, reassurance or neutralising.
