How Does Acceptance And Commitment Therapy (ACT) Work?

relationship good and bad reactionsAcceptance and Commitment Therapy (ACT) encourages people to embrace their thoughts and feelings rather than fighting or feeling guilty for them.

It may seem confusing at first, but ACT paired with mindfulness-based therapy offers clinically effective treatment. After all:

Running away from any problem only increases the distance from the solution. The easiest way to escape from the problem is to solve it.

Medical conditions such as anxiety, depression, OCD, addictions, and substance abuse can all benefit from ACT and Mindfulness-Based Cognitive Therapy (MBCT).

ACT develops psychological flexibility and is a form of behavioral therapy that combines mindfulness skills with the practice of self-acceptance. When aiming to be more accepting of your thoughts and feelings, commitment plays a key role.

In the case of ACT, you commit to facing the problem head-on rather than avoiding your stresses. Imagine committing to actions that help you facilitate your experience and embrace any challenge.

As you will see later in this piece, ACT is effective for a wide range of psychological disorders, and it is also effective as a life-affirming and inspirational perspective of self-determination.

What if you could accept and allow yourself to feel what you feel, even if it’s negative?

What is Acceptance and Commitment Therapy (ACT)? Definitions and Core Processes

The website explains ACT in simple terms: it is a type of therapy that aims to help patients accept what is out of their control, and commit instead to actions that enrichen their lives (Harris, 2013).

According to the Association for Contextual Behavioral Science (ACBS), ACT is:

“a unique empirically based psychological intervention that uses acceptance and mindfulness strategies, together with commitment and behavior change strategies, to increase psychological flexibility.”

The ACBS views ACT as a therapy based on the concept that suffering is a natural and inevitable condition for humans. We have an instinct to control our experiences, but this instinct does not always serve us.

The founder of ACT has also offered a definition of ACT in terms familiar to the psychology field:

“a psychological intervention based on modern behavioral psychology, including Relational Frame Theory, that applies mindfulness and acceptance processes, and commitment and behavior change processes, to the creation of psychological flexibility”

(Hayes, “The Six Core Processes of ACT”).

To put it in less clinical terms, Dr. Russell Harris (2011) has defined ACT as a mindfulness-based behavioral therapy that challenges the ground rules of most Western psychology.” Its unique goal is to help patients create a rich and meaningful life and develop mindfulness skills alongside the existence of pain and suffering.


Core Processes

Six core processes of ACT guide patients through therapy and provide a framework for developing psychological flexibility (Harris, 2011). These six core processes of ACT include the following:

  • Acceptance;
  • Cognitive Defusion;
  • Being Present;
  • Self as Context;
  • Values;
  • Committed Action.

Acceptance is an alternative to our instinct to avoid thinking about negativeor potentially negativeexperiences. It is the active choice to allow unpleasant experiences to exist, without trying to deny or change them.

Acceptance is not a goal of ACT, but a method of encouraging action that will lead to positive results.

Cognitive Defusion refers to the techniques intended to change how an individual reacts to their thoughts and feelings. Acceptance and Commitment Therapy does not intend to limit our exposure to negative experiences, but rather to face them and come out the other side with a decreased fixation on these experiences.

Being Present can be understood as the practice of being aware of the present moment, without judgment the experience. In other words, it involves experiencing what is happening without trying to predict or change the experience.

Self as Context is the idea that an individual is not simply the sum of their experiences, thoughts, or emotions. The “self as context” process offers the alternative concept that there is a self outside of the current experience.

We are not only what happens to us. We are the ones experiencing what happens to us.

Values in this context are the qualities we choose to work towards in any given moment. We all hold values, consciously or unconsciously, that direct our steps. In ACT, we use tools that help us live our lives in accordance with the values that we hold dear.

Finally, ACT aims to help patients commit to actions that will assist in their long-term goals and live a life consistent with their values. Positive behavior changes cannot occur without awareness of how a given behavior affects us.

ACT is not all that different from other behavioral-based therapies; it just emphasizes acceptance instead of avoidance, and in that way, differs from many other forms of therapy. This departure from most mainstream treatment can be traced back to the background of ACT’s founder, Stephen C. Hayes.


Steven C. Hayes and ACT

Steven C. Hayes, a psychology professor at the University of Nevada, developed ACT in 1986 (Harris, 2011). His work began with how language and thought influence our internal experiences and laid the foundation for ACT.

Hayes disagreed that suffering and pain are to be avoided and buffered whenever possible. He saw suffering as an inevitable and essential part of being human, as well as a source of fulfillment when we do not flee from what scares us.

Steven Hayes makes a compelling case for acceptance and self-compassion based on his own experiences with pain. His TED Talk on psychological flexibility explains the foundation for his psychological exploration of ACT.


The Role of ACT in Psychology and Mindfulness

The Role of ACT in Psychology and Mindfulness apple orangeAcceptance and Commitment Therapy is built on the Relational Frame Theory, a theory based on the idea the human ability to relate is the foundation of language and cognition.

Relating involves noting the dimensions along which relation exists. For example, we may associate an apple with an orange, but our ability of relating allows us to understand that although they have a similar shape (round) and function (to be eaten), they have different colors and textures.

Humans, unlike most other animals, have an uncanny ability to relate even neutral events, as well as seemingly unrelated words and ideas.

While this is an advantageous ability, it also facilitates negative thoughts and judgment about ourselves. If we can relate the word “cookie” to the experience of eating a cookie, then we can also relate the word “worthless” to feeling that we are worthless.

Our ability to form relational networks (e.g., I relate the words “orange”, “apple”, and “pear” to the concept of “fruit”) can be a destructive ability when anxiety and depression impact us.

For example, we might relate “worthless” to an ability to perform my job and, by extension, relate the word “worthless” to my life. ACT is built on Relational Frame Theory.

We often form relational networks that are not complimentary or life-giving, but we can also change those relations when we apply mindfulness to accept our feelings and change how we react and relate to them, instead of trying to avoid them.

For a more detailed explanation of Relational Frame Theory, you can check out this PDF from Act Mindfully, a web resource revolving around principles of ACT.


10 Worksheets, PDF’s, PPT’s and ACT Resources

Are you ready to use ACT as a way to improve your life or the life of your clients? If so, read on for excellent resources to apply the science of Acceptance and Commitment Therapy to your work.

Many of these are made available by the organization ACT Mindfully, which is a great resource.

Follow this link for a PDF that includes several worksheets and lots of information on how to guide a client through them.


1. Triggers, Behaviors, and Payoffs (page 7)

This worksheet is a fillable matrix on page 6 with one column for writing down triggers (situations, thoughts, or feeling that immediately precede a certain behavior), behaviors (what you actually do), and payoffs (the immediate outcomes of the behavior that encourage the behavior to continue).

This worksheet can help you or your clients identify self-defeating behaviors with the motivation behind them, which can be a first step to recognizing and modifying problematic behavior.


2. Bull’s Eye: Clarifying Your Values (page 9)

Another worksheet presents the Values Bull’s Eye, or a set of concentric circles that are separated into four quadrants: work/education, leisure, personal growth/health, and relationships.

The exercise involves placing an “X” on the circle that most closely represents how you feel in the present moment.

The closer to the middle the X is, the more you feel you are behaving like the person you want to be. The further out the X is, the less you feel like the person you want to be. This worksheet can be found in the PDF above on page 11 or individually here.


3. The ‘Triflex’ Psychological Flexibility Assessment Tool (pages 14-15)

The final pages in the PDF from ACT Mindfully help you estimate your psychological flexibility based on three factors:

  1. Ability to open up
  2. Ability to be present
  3. Ability to do what matters

Here you will find a visual representation of psychological flexibility, an explanation of each of these three factors, and a method of estimating your abilities in these areas at this moment.


4. “The Happiness Trap” Worksheets

Another PDF packed with worksheets is provided by This PDF can be found here, and includes these worksheets:

The Cost of Avoidance Worksheet (pages 4-5)

This worksheet present four sentences for you to complete:

  1. The thoughts I’d most like to get rid of are:
  2. The feelings I’d most like to get rid of are:
  3. The sensations I’d most like to get rid of are:
  4. The memories I’d most like to get rid of are:

Next, you are asked to write a list of everything you have done to try to avoid or get rid of these thoughts, feelings, sensations, and memories. Distracting yourself from these, avoiding activities, or using substances to self-medicate are a few examples of avoidance techniques.

Then you are asked to consider these questions for each item:

  1. Did this action get rid of my painful thoughts and feelings in the long term?
  2. Did it bring me closer to a rich, full, and meaningful life?
  3. If the answer to question 2 is “no,” then what did this action cost me in terms of time, energy, money, health, relationships, and vitality?

This worksheet can help you become aware of your own avoidance strategies, and whether they are producing the results you want.

Informal Mindfulness Exercises (page 9)

This page introduces two simple mindfulness exercises for any typical day:

  1. Mindfulness in Your Morning Routine: This exercise encourages you to notice the sensations while getting ready in the morning, such as the taste of your toothpaste, the smell of your face wash, or the feel of hot water on your body in the shower.

  2. Mindfulness of Domestic Chores: This exercise is one you can practice by simply being aware of the sensations you experience as you sweep the floors, do a load of laundry, or make dinner. Since you “always” have to do the dishes, why not take the time to do it mindfully? It’s good for your brain.

This worksheet allows space for you to imagine some informal mindfulness exercises to add to your day, such as while waiting in traffic or while walking from your car to your door. Maybe it’s as little as “no-phone” time while you grocery shop or wait in line.

Values Assessment Rating Form (page 12)

The Values Assessment Rating Form provides a matrix with 10 life domains (e.g., couples/intimate relationships, parenting, employment, etc.) and 4 columns to fill out:

  • Valued direction (a brief summary of your goal for each domain)
  • Importance of this value in your life
  • Success in living this value
  • Rank in order of importance you place on working on this domain right now

The Values Assessment Rating Form can help you identify where you are falling short of your goals and where you are meeting your goals, as well as aiding the prioritization of meeting these goals going forward.

Goal Setting Worksheet (page 16)

This worksheet guides the reader through the values that underlie their goals and how to make sure these goals are SMART goals. SMART is an acronym for goals that are Specific, Meaningful, Adaptive, Realistic, and Time-bound.

This activity will help you understand how to set goals that you can meet, rather than lofty ideas that are not backed by concrete actions.

What To Do in a Crisis (page 20)

This informational page offers a practical and useful response for when you face a crisis.

This response is called STOP:

  • Slow your breathing: enter into a quick and simple mindfulness practice.
  • Take note: noticing what you are experiencing in the present moment.
  • Open up: allow yourself to feel without judgment or avoidance.
  • Pursue your values: decide what the best course of action is based on your most important values.

Here is a list of things to consider during this exercise:

  1. Consider if you need assistance or support, and who could provide you with the assistance or support you need.

  2. Think about whether you have experienced anything similar before, and how you responded to it then.

  3. Consider ways to improve the situation, even in the smallest way, whether it’s in the next few minutes or the next few days.

  4. Be willing to practice acceptance if you cannot improve your situation, and commit to spending your time and energy in a constructive way.

  5. Ask yourself what the best way is to deal with this situation or, as the metaphor goes, how to play the game with the cards you have been dealt.

  6. Remember to practice self-compassion; if you need inspiration, imagine a friend or loved one was going through your experience right now, and tell yourself whatever you imagine telling them.


5. Psychological Inflexibility

For therapists and other mental health professionals, this PDF from The HappinessTrap aligns with ACT principles as well. It provides questions for you to assess your clients for their psychological inflexibility.

Psychological inflexibility is the extent to which anyone has trouble practicing the six core processes. The questions map to the opposite of the six core processes as follows:

  • The dominance of the conceptualized past or future; limited self-knowledge (vs. acceptance)
  • Fusion (vs. defusion)
  • Experiential avoidance (vs. being present)
  • Attachment to the conceptualized self (vs. self as context)
  • Lack of values clarity/contact (vs. values)
  • Unworkable action (vs. committed action)

This set of questions can be a great tool to help your clients ascertain where to focus their energy. This is a critical step to embracing their experiences and act according to their deepest values.

7 Useful ACT Exercises, Techniques, and Metaphors

Applying Mindfulness to Your Therapeutic PracticeThe section above includes several resources with Acceptance and Commitment Therapy practices, and now we’ll describe the most popular exercises and metaphors in detail=.

Several of these can be found on the Association for Contextual Behavioral Science website, on their ACT exercises page or their ACT metaphors page. For each exercise or metaphor, a link will be provided to the exercise for you to learn more.


Writing Acceptance Exercise by Matthieu Villatte

This is a quick exercise for mental health professionals to help their clients understand how avoidance can be counterproductive. This exercise can be completed in the following steps:

  • Give your client a sheet of paper and a pen and ask them if they are ready for written instructions.

  • Before the client can write anything, present an obstacle that obstructs the client’s ability to see the paper and pen (e.g., a piece of cardboard, a mask with severely limited vision, etc.)

  • Ask the client if this bothers them and if they’d rather be able to see as they write. Inform them that the obstacle will stay, but they should still attempt to work around the obstacle in order to write the sentence.

  • Let them struggle with seeing around the obstacle for 20 to 30 seconds. They probably will not have written anything readable at this point.

  • Ask the client about their experience (i.e., “How was it? Was it difficult? Were you able to write the sentence? Can we read it?”)

  • Propose that the client stop trying to see around the obstacle, but just accept that it is there and write the sentence anyway.

  • The sentence they write when focusing on writing (instead of avoiding) will likely be more readable. Point this out to them and help them make the connection between avoiding the physical obstacle and avoiding emotional pain, and the negative consequences of each.

You can find this exercise in more detail here.


Two Sides of the Same Coin by Jenna LeJeune

This exercise can be guided by a therapist or completed on your own. Following these steps can help you or your client understand that suffering is an inevitable part of life; if we eradicated suffering, we would also eliminate joy.

Follow these steps to give this exercise a try:

  • Find an activity or relationship that you find valuable, but that you have retreated from recently;

  • Take out an index card or piece of paper. On one side, write down what you value about that activity or relationship or what you hope to achieve or become through it;

  • On the other side, write down the difficult thoughts and feelings that sometimes happen for you, when you take action towards gaining the value or achievements written on the other side;

  • Put the card in your pocket, wallet, or purse. Over the next week, take it out, look at both sides, and ask yourself if you are willing to have that card, with both the good and bad. You can either avoid both the value and the pain, or you can embrace them both.

For more information on this exercise and the story behind it, check it out here, and look here for a similar exercise from ACBS.


Mindfulness of Emotions by Carol Vivyan

This is a mindfulness technique that can defuse a strong, negative emotion. Follow the steps to renew your focus on acceptance and positive action toward your values:

  1. Sit comfortably in a quiet area. Bring your attention to your breath, feeling the sensations of breathing without trying to manipulate your breath;

  2. Notice the emotion(s) you are feeling, and what it feels like;

  3. Name the emotion. Identify what it is and what word best describes how you are feeling;

  4. Accept the emotion as a natural and normal reaction to the circumstances. Don’t condone it or judge it, just let it move through you;

  5. Investigate the emotion by asking questions like: How intensely am I feeling this emotion? Has my breathing changed? What are the accompanying sensations in my body? How is my posture? Am I experiencing increased tension in my muscles? What is my facial expression at this moment? How does my face feel?

  6. Notice the thoughts or judgments that arise, but let them pass. If you find yourself dwelling on any of them, gently bring your attention back to your breathing to re-center, then visit the emotion again. This technique may produce the best results when starting small and working your way up to more intense emotions.

The Valued Directions Worksheet by John Forsyth and Georg Eifert

This exercise is a great first step for anyone looking to start practicing ACT techniques. Values, as mentioned earlier, are a foundational piece of Acceptance and Commitment Therapy.

The Valued Directions worksheet presents 10 value domains for the reader to consider:

  • Work/career;
  • Intimate relationships;
  • Parenting;
  • Education/learning/personal growth;
  • Friends/social life;
  • Health/physical self-care;
  • Family of origin (or relationships other than marriage or parenting)
  • Spirituality Community life/environment/nature;
  • Recreation/leisure;

The exercise then asks the reader to rate the importance of each value domain on a scale of 0 (not at all important) to 2 (very important). There is nothing wrong with valuing some areas more than others.

Then, readers rate their satisfaction with their lives in each area on a scale of 0 (not at all satisfied) to 2 (very satisfied).

Once the ratings have been completed, the exercise asks readers to review any value rated as a 1 or 2 on the importance scale and write their intentions in that area for the foreseeable future. In other words, write down what you want to achieve, maintain, or become in each important value area.

These are not goals that can be completed and “checked off,” but rather they are actionable goals that match how you want to live your life each day.

This exercise can help clarify what is important and needs to be prioritized in your life. It’s best if you have a therapist or qualified professional to discuss the results and actionable goals with. It is still a powerful exercise whether you are currently attending therapy or not.

To give this exercise a try, follow this link.

Metaphors also play a key role in Acceptance and Commitment Therapy. They provide clients with a simple way to understand how their feelings and thoughts influence their actions, and thus, allow people to visualize how adjusting our thoughts affects our behaviors.

Here are three of our favorite metaphors relevant to ACT.


The Sailing Boat Metaphor

The Sailing Boat Metaphor act This metaphor uses the setting of a small sailing boat, with “you” as the sailor.

Occasionally, waves send water over the side and into the boat, causing you the inconvenience of wet feet. The boat includes a bailer to bail out this water, and you know how to use it.

So one day, when a particularly big wave breaks over the side and leaves water in your boat, you start bailing. You may start bailing calmly or mindfully, but eventually, you might find yourself bailing desperately or wildly to get rid of all this water.

While you’ve been bailing, have you noticed what is happening to your boat? Where is it headed? Where has it drifted to? Would it be fair to say you’ve been bailing more than sailing?

Now imagine that you take a look at the bailer and see that it is really a sieve, full of holes? What would you do?

The implicit purpose of bailing water here is probably to get your boat back on trackonce you rid the boat of the water. But if your tool is not suited to the task, you will find yourself struggling to get rid of any water, let alone guide your boat.

The question is would you rather be on a boat that has only a little water in the bottom, but is drifting without direction, or on a boat that may have quite a bit of water in the bottom but is heading in the direction you wish to go?

This metaphor can help you or your clients realize two things:

  1. The techniques we use to deal with our problematic thoughts and feelings are tools like the bailer and the sieve, and some are better than others.

  2. Sometimes working desperately to avoid wet feet (or other painful or uncomfortable feelings) gets us so off-track; the distraction and struggle of “wet feet” become our blocks to reaching our goals, not the waves.

To read this metaphor in its entirety, see this link.


The Mind Bully Metaphor

This metaphor is meant for people struggling with a particular emotion or diagnosis, like anger, anxiety, or depression.

In this metaphor, the mind bully is our particular problem: it is an extremely large and strong bully. We are on opposite sides of a pit, tugging back and forth on a rope as the Mind Bully tries to make us fall into the pit.

When we pull on the rope, when we listen and pay attention to or even believe the monster, we are actually feeding it. Like any bully, the Mind Bully can only harm us when we engage with it and believe the negative things it says. In other words, don’t let your mind bully your body.

Instead of pulling on the rope, what do you think would happen if we drop it? The Mind Bully might still be there, hurling its insults and meanness, but it would no longer be able to pull us towards the pit.

The less that we feed the Mind Bully, the smaller and quieter it will get. Maybe eventually, we even will grow empathy for this sad creature and wonder why it says such mean thoughts.

We stop feeding the Mind Bully by noticing and acknowledging it but shifting our attention away from it instead of believing what it says. Engaging in a quick mindfulness exercise can be a great way to do this.

To learn more about the Mind Bully metaphor and read the alternate version of this metaphor, visit this website.


The Quicksand Metaphor

Quicksand is a loose, wet patch of sand that cannot support weight like dry sand can. When you step in quicksand, you start to sink instead of finding a solid footing.

Common knowledge is that struggling against quicksand only increases the rate at which it sucks you down into its depths. When you put more weight on one foot to try to lift the other, it just sinks deeper into the pit. The more you struggle, the deeper you sink. Frightening!

The solution to surviving quicksand is to spread your body weight over a large surface area and move slowly.

Rather than trying to stand and fight the quicksand, ignore your instincts to struggle and lie down on your back instead.

It’s counterintuitive, but the less you struggle and the more you accept your present situation and embrace vulnerability, the easier it is to escape.

This same principle applies to pain, suffering, and knowing when to ask for help. The more we struggle and fight against it, rather than accepting our situation, the more we drag ourselves down deeper.

When we accept that the suffering is inevitable, we are more likely to survive and come out the other side more quickly and efficiently.

To learn more about this metaphor, you can read about it here or watch a short YouTube video about it here.

If you find metaphors to be useful tools in your own life or your clients’ lives, you can read more metaphors in The Big Book of Metaphors: A Practitioner’s Guide to Experiential Exercises and Metaphors in Acceptance and Commitment Therapy by Jill Stoddard, Niloofar Afari, and Steven C. Hayes.

ACT for Treating Disorders

Like the practice of mindfulness, ACT can be applied in any individual’s life and help with general anxiety disorders, chronic pain, depression, OCD, eating disorders, and social anxiety.


General and Social Anxiety Disorders

Many studies showcase the positive effects of this form of therapy for patients struggling with anxiety.

For example, one study showed that college students who received ACT treatment enjoyed less stress in regards to academic concerns, decreased anxiety and depression symptoms, greater general mental health, and improved mindful acceptance (Levin, Haeger, Pierce, & Twohig, 2017).

Another study reiterated these positive impacts on anxiety and showed that ACT delivered via the internet could be as effective as therapist-delivered ACT (Ivanova et al., 2016).

The participants in this study reported reduced general and social anxiety, whether they were in the “treatment as usual” group or the online ACT group.

To learn more about how to apply Acceptance and Commitment Therapy to anxiety disorders, check out this website that is packed with information on how ACT can help treat anxiety and why it works. This site focuses on important points like mindfulness, commitment, and control paradox, which arises from our expert ability to control our environment paired with our relative inability to control our thoughts and emotions.

If you want to treat anxiety with ACT, we recommend the following book, Acceptance and Commitment Therapy for Anxiety Disorders: A Practitioner’s Treatment Guide to Using Mindfulness, Acceptance, and Values-Based Behavior Change Strategies. This book can be found here.

Georg H. Eifert, John P. Forsyth, and Steven C. Hayes offer real and tangible changes for therapists and clients alike.


Chronic Pain

Acceptance and Commitment Therapy has been found to improve quality of lifeeven without affecting the level of pain experiencedfor many cases of chronic pain.

One study showed that cancer patients who receive ACT treatment reported significant improvements in the acceptance of their circumstances and finding increased meaning in life, even while still experiencing pain (Datta, Aditya, Chakraborty, Das, & Mukhopadhyay, 2016).

Another study also found that ACT improves psychological flexibility and reduces depressive symptoms, even when chronic pain remains (Scott, Hann, McCracken, 2016).

A different study verified this finding, reporting that physical and emotional functioning improved with ACT, even with no concurrent reduction in pain (Vowles, Witkiewitz, Levell, Sowden, & Ashworth, 2017).



Similarly, ACT has been found to improve symptoms for people suffering from depression. One study found that ACT decreased the severity of depressive symptoms for veterans with depression and suicidal thoughts (Walser, Garvert, Karlin, Trockel, Ryu, & Taylor, 2015).

ACT also reduced psychological inflexibility and distress related to depression and anxiety in older adults, even with only a brief course from a novice ACT therapist (Roberts, 2016).

If you’d like to learn more about using Acceptance and Commitment Therapy to treat depression, give this book a try: ACT for Depression: A Clinician’s Guide to Using Acceptance and Commitment Therapy in Treating Depression, by Robert Zettle. It describes how ACT can contribute to the successful treatment of depression by providing a session-by-session approach.


Obsessive-Compulsive Disorder (OCD)

ACT can also help patients suffering from Obsessive-Compulsive Disorder (OCD).

An overview of the quantitative research conducted in this area showed that ACT treatment for OCD is as effective as the “treatment as usual” approach, including cognitive behavioral therapy (Bluett, Homan, Morrison, Levin, & Twohig, 2014).

For a great explanation of how to apply ACT in the treatment of patients with OCD, check out Michael Twohig’s piece on this subject.

He explains that ACT can be applied to OCD treatment by viewing behaviors as changeable rather than inherent biological responses. He offers ways to focus on clients’ reactions to events, instead of seeing their behaviors as fixed facets of their personality.


Eating Disorders

Finally, ACT has also been successfully applied to patients with eating disorders. A case-series study on women with Binge Eating Disorder showed that participants improved with the application of ACT (Hill, Masuda, Melcher, Morgan, & Twohig, 2015).

One patient even reached a point where her symptoms no longer met the clinical definition of Binge Eating Disorder, while both displayed increases in their body image flexibility.

In a study on patients with anorexia, participants who received treatment that included ACT were more likely to reach positive outcomes at the end of the study (Parling, Cernvall, Ramklint, Holmgren, & Ghaderi, 2016).



Applying ACT in Group Therapy

Applying ACT in Group TherapyAcceptance and Commitment Therapy can be applied on an individual level, but it is also effective when delivered via a treatment group.

The Association for Contextual Behavioral Science acknowledges the effectiveness of group ACT treatments for anger, depression and general anxiety, social anxiety, chronic pain, and for struggling adolescents.

The Houston Group Psychotherapy Society reiterates the effectiveness of group ACT therapy, noting that a group setting can provide opportunities for clients to connect and learn from one another, receive the validation they may desperately need, and practice constructive vulnerability.

The HGPS also lays out some advice for applying ACT in a group (learn more about group therapy here):


Group Rules

Set rules for the group (show up to each group ready to make it work, don’t try to “solve” another group member’s feelings, conversations within the group are not expected to continue outside of this context etc.) and make sure group members know they must be followed.


Group Format and Structure

Decide on whether the group is more general or for a more specific topic like anxiety or depression. Consider starting the group with a mindfulness exercise or keeping a quick mindfulness exercise in your back pocket in case a group member gets off track.


Experiential Exercises

Don’t be afraid to include experiential exercises but be on the lookout for judgment from group members after the exercise.



When conflict arises, which is likely to happen at some point, guide the group member to their inner experience first. Help them bring their thoughts back to making therapy work for them. Be ready to experience discomfort. Avoid the urge to “rescue” group members from their pain. As some therapists say, “don’t steal the struggle,” as it is sometimes a key part of the group’s process of establishing trust for each other.

For more information on applying ACT in groups, see the humorously named The Idiot’s Guide to ACT in Groups. This workbook provides a practical outline for setting up and conducting group ACT therapy and includes models, techniques, exercises, and basic protocols for group ACT.


4 Helpful YouTube Videos

If you learn more efficiently from videos than books, then here are some fantastic ACT videos on YouTube to learn more about ACT techniques.

For a great overview of ACT videos, begin with Dr. Russ Harris’ YouTube channel here. He has several ACT videos for different audiences and techniques. For example, one upload is for specifically for adolescents who want to harness ACT to “stop struggling and start thriving.”

If you’re looking for a short and sweet introduction to Acceptance and Commitment Therapy, the video below comes from the Veterans Health Administration.


If you’d like to learn more about the metaphors applied in Acceptance and Commitment Therapy, this video from Joe Oliver explains the ACT metaphor of passengers on a bus. In this metaphor, we are asked to place ourselves in the role of the bus driver, the person who has control over the speed and direction of the bus, but not the passengers.

Just as we cannot control the passengers who board the bus, we cannot control our own internal experiences, but we can allow them to say their piece while maintaining control over the bus. It’s only five minutes and features engaging animation.


Another great video from Joe Oliver outlines the unwelcome party guest metaphor. This video is just over four minutes and shows how trying to avoid things can backfire. Instead of avoiding the negative experiences that cause us stress or emotional discomfort, allowing ourselves to experience them and learn from them can produce far better results.

What if our depression, or anxiety, was “that unwelcome party guest” we should allow space for at the party?


Our final metaphor video from Joe Oliver images one of the demons on the boat. In this metaphor, we are steering the boat with a horde of angry, aggressive, and intrusive demons in the water below us. If you’re wondering how this translates to helpful ACT tactics, watch the video below.

You may be entertained and surprised.


Which of these videos resonates best for you? When you finish this article, we would love to hear from you in our comments section.

    This was great! Thank you so much!

  2. Shawn Rice

    Please explain how Acceptance and Commitment Therapy works. I am trying to do a presentation for my mom to look at (of course) so that then she can learn about what Acceptance and Commitment Therapy is and how it works and many other topics about Acceptance and Commitment Therapy.

    • Nicole Celestine

      Hi Shawn,

      In addition to the details throughout this article, professional ACT trainer, Dr Russell Harris, has a great little PDF handout that succinctly explains the process and benefits of ACT, which applies many of the same principles of mindfulness. You can download that here. 🙂

      Hope this helps!

    This was such a joy to read! Thank you for such a great article!

    I think this has been a useful explanation of ACT. Stripped back to its basics in practice, the most important parts of it are getting clients fo face their feelings and to work through them. Always good to pick out the positive aspects of seemingly negative experiences – simply flipping a negative is a technique I use quite often in practice,

  7. E.J. Kim

    Thank you for such a thorough article pack with helpful links and resources. I feel lucky and overjoyed to be stumbled upon your article.

  8. David Norriss

    I like how you said that the first step to recognizing and changing a person’s problematic behavior is identifying their self-defeating behaviors and their motivation. My best friend is always beating herself up over her inability to do things right. I’ll see if she wants to go meet with a therapist and have them analyze her self-defeating behaviors so they can help her change.

    Mindfulness and Commitment:
    Below for your consideration is a brief explanation of how a simple variation of mindfulness procedure can elicit peak, ecstatic, or ‘flow’ states. It is based on the incentive motivation theory (a radical or bio-behaviorism) of the distinguished neuroscientist Dr. Kent Berridge of the University of Michigan, who was kind to vet the argument for accuracy and endorse the work (in preface in linked MS below). The procedures endorsed parallels closely those endorsed in ACT, however the argument is derived from a radical behaviorism, not a behavioristic theory of language (RFT).
    As an academically trained psychologist but layman, and per the pragmatic principles of behaviorism my argument rises or falls on procedure, theory is a matter of justification, and is offered in the links below.
    On Mindfulness and Commitment
    1. Opioid systems (pleasure) are activated when the covert musculature is inactive or relaxed, and suppressed when the covert musculature is active (a state of tension).
    2. Dopamine systems (attentive arousal) are activated upon the perception or anticipation of positive act-outcome discrepancy (or novelty) and are suppressed when present or anticipated outcomes are predictable or negative (boredom, depression).
    3. When concurrently activated, opioid and dopamine systems can interact and co-stimulate each other, and result in self-reports of ecstatic or peak experience.
    Concurrent response contingencies that induce relaxation (e.g. mindfulness protocols) and attentive arousal (e.g. meaningful behavior) will result in the co-activation of both systems with self-reports of arousal and pleasure that are subjectively reported as ‘flow’ or ‘peak’ experiences.
    Self-reports of peak experiences without exception occur during states of relaxation coupled with the continuous anticipation of high and positive act-outcome discrepancy (e.g. creative, sporting, and other meaningful behavior). (pp.82-86 of linked book below). Besides its face validity, the hypothesis also provides the procedural means for its easy falsification. (pp. 47-52). To wit, simply consistently engage in mindfulness (a relaxation protocol) while consistently pursuing meaningful behavior, and you will feel alert, aroused, and feel good to boot. That’s it.

      Hi Arlene – that sounds like a fantastic idea! I wish I could be of more help, but I have little expertise in the realm of education. Perhaps a positive developmental specialist could help? Thanks for commenting!
