ACT (Acceptance and Commitment Therapy): principles and benefits

There are times when the mind feels like a room full of voices. One says "you have to control it," another says "it's going to go wrong," and yet another repeats memories and fears as if trying to prevent the future.

The more we try to push these thoughts out, the more they come back. This is precisely where ACT (Acceptance and Commitment Therapy) becomes relevant: instead of waging war with what we feel inside, it helps us create space, clarity, and direction.

In this article, you will understand what ACT is, what its central principles are, and why, for many people, the benefits appear when they stop seeking to "always feel good" and begin to live in a way that is more aligned with their values.

What is ACT (Acceptance and Commitment Therapy)?

ACT is a therapeutic approach that seeks to increase psychological flexibility. In simple terms, psychological flexibility is the ability to be present, recognize what is happening internally (thoughts, emotions, sensations) and still choose helpful actions, even when discomfort exists.

ACT does not attempt to forcibly eliminate difficult thoughts, nor does it promise a life without them. anxiety. The focus is on reducing the impact that these internal events have on daily choices, so that the person stops living "in fear" and starts living "in what matters.".

Who is the ACT useful for?

ACT is used for various difficulties and emotional patterns. More than just "diagnoses," it's especially helpful when there's a cycle of internal struggle that's robbing you of energy and freedom.

This can be particularly relevant when:

• There is persistent anxiety and constant worry. many people with anxiety They try to control the future and end up feeling even more trapped.

• There is prolonged sadness and disconnection from what previously gave meaning: in frames of depression, The tendency may be to avoid anything that hurts, which sometimes increases isolation.

• There is emotional exhaustion and a feeling of being on "autopilot":  ACT can help clarify priorities and boundaries in contexts of Burnout.

• There are intrusive thoughts, rumination, and self-criticism. Not because "thought is dangerous," but because the relationship with it has become suffocating.

The most common misunderstanding: acceptance is not resignation.

Many people turn their noses up at the word "acceptance." It seems that accepting means giving up, conforming, or approving of something unjust. In Acceptance and Commitment Therapy, that's not the case.

Acceptance means:

• to recognize the internal experience as it is, in this moment.

• Stop wasting energy fighting against unavoidable emotions.

• Create space to choose the best possible course of action, even if it's uncomfortable.

Resignation means "there's nothing to be done." Acceptance means "this is here, and I can choose how to respond." The difference is enormous.

The 6 principles of ACT

ACT is often described through six processes that work together. These are not rigid "steps," but rather areas that reinforce each other.

1) Presence at the moment

When we are stressed, the mind lives in the past (guilt, regret) or in the future (fear, anticipation). Being present in the moment is the ability to return to the now, not to deny problems, but to regain our footing.

It is in the present moment that decisions are made, communications take place, rest is found, limits are set, and the first step is taken.

A tool closely related to this idea is attention training, often worked on with practices such as mindfulness for anxiety, adapted to each person's reality.

2) Acceptance of internal experiences

Accepting is not about liking what you feel. It's about allowing emotions and sensations to exist without fighting against them.

A practical example:

• fighting anxiety: “"I can't feel this, I have to stop now"”

• Accepting anxiety: “"This is uncomfortable, but I can stay here and choose my next step.".

Interestingly, when the fighting subsides, the emotion often loses intensity on its own.

3) Cognitive defusion

Defusion is learning to see thoughts as thoughts, not as orders or absolute truths.

• Instead of: “"I'm going to fail"”
• It becomes: “"I'm having the thought that I'm going to fail."”

This small change creates distance. And that distance restores freedom. Defusion is useful when the mind becomes repetitive, critical, or catastrophic. Instead of arguing with thought, the person learns to observe and to choose.

4) Me as context (the observer)

This principle helps you realize that you are not the content of your mind. You are the person who:

• note the thought

• note the emotion

• note the memory

By strengthening this "observer," it becomes easier to navigate difficult times without collapsing into the idea of "this is who I am.".

5) Clarification of values

Values are not objectives. Objectives are things that complement each other. Values are directions.

• objective: “"change jobs"”

• value: “"growth", "autonomy", "contribution", "balance"”

ACT helps identify what truly matters, so that decisions cease to be mere reactions to fear and become meaningful choices.

6) Committed action

After clarifying values, the next step is to act consistently, even when discomfort arises.

The action committed is:

• small and repetitive.

• Realistic and sustainable.

• Guided by values, not by impulse.

Here's a key point: it's not about "forcing" or "being strong." It's about building trust through aligned actions, even if imperfect.

Benefits of ACT (what tends to change in practice)

The benefits of ACT often emerge in two ways: less mental confinement and a life lived with more intention.

Some common changes reported in therapy:

• Less time wasted arguing with thoughts: The mind may continue to speak, but it ceases to be in control.

• Less avoidance: Instead of running away from emotions, one learns to navigate them safely.

• More clarity in decision-making: The focus shifts from "how do I stop feeling this way?" to "what is important for me to do now?"“

• greater tolerance for uncertainty: without needing perfect guarantees to move forward.

• more connection with real life: Relationships, routines, self-care, projects, rest.

• More self-compassion and less self-criticism. The requirement may exist, but it ceases to be cruelty.

ACT vs. other approaches: what makes it different?

ACT shares similarities with cognitive behavioral therapy, but its focus is usually less on "changing the content of thought" and more on "changing the relationship with thought.".

Instead of trying to prove that thought is irrational, ACT asks:

• Does this thought help me live the life I want?

• When I follow this mental narrative, do I become more free or more trapped?

This is particularly useful for those who have already tried "positive thinking" and felt that it only increased their frustration.

A simple example to understand ACT

Imagine you have a recurring thought: "I'm not capable."“

A common pattern is:

• to believe: “"If I thought this, it's because it's true.".

• to fight: “"I have to prove that I'm capable now.".

• avoid: To postpone, to give up, not to try.

ACT invites you to explore another option:

• note: “"I'm having the thought 'I'm not capable'"‘

• make room: “"This is uncomfortable, but I can tolerate it."”

• Choose by value: “"What matters here? Learning? Caring? Growing?"”

• Act small: a short task, one step at a time

The idea is not to eliminate thought. It's to prevent it from shutting down your life.

What to expect from ACT-based therapy?

In a collective bargaining agreement (CBA) process, it is common to work with:

• Identifying avoidance patterns: What it avoids, how it avoids it, and what the cost is.

• Defusion and presence training: Tools to reduce "stuffiness" in thoughts.

• clarification of values: what it wants to represent, even on difficult days.

• building committed actions: Small, consistent steps, adapted to the context.

It is also common to use metaphors and experiential exercises, because there are things that cannot be learned simply by "thinking," but rather by feeling and practicing.

Common mistakes when trying to apply ACT on your own.

ACT is simple in theory, but challenging in practice. There are frequent pitfalls.

• Using acceptance to avoid action: “"I accept this, so I'm not doing anything.".

• Using defusion as a trick to make thoughts disappear: “"I do this to get rid of it.".

• Transform values into a list of requirements: “"I have to be perfect in my values.".

• Using mindfulness to switch off emotions: as if the presence were anesthesia.

When this happens, the problem isn't "glitch." It's that the mind is trying to transform ACT into a control strategy. And ACT doesn't work well as a control mechanism.

How to start engaging with ACT in everyday life

Without replacing therapy, there are two questions that already change a lot:

• “"What am I trying to avoid feeling?"”

• “"If I weren't trapped by this fear, what would I do toward what I value?"”

Next, choose a small gesture:

• a conversation that has been postponed

• a simple limit

• a short task

• basic care

The goal is to train driving skills, not perfection.

Conclusion

ACT is not an invitation to "endure everything." It's an invitation to stop living according to internal struggles and to reclaim the ability to choose. When you learn to give space to what you feel, to break free from the fusion with your thoughts, and to act guided by values, life stops shrinking.
