What Is Acceptance and Commitment Therapy (ACT)? How It Works
Acceptance and Commitment Therapy — usually called ACT (said as one word, "act") — is an evidence-based form of psychotherapy that takes a different approach from many traditional therapies. Instead of trying to eliminate difficult thoughts and feelings, ACT helps you accept them while committing to actions that reflect your values. This guide explains what ACT is, the core principles behind it, how it works in practice, and what it can help treat. Learn more about addiction treatment resources.

What Is Acceptance and Commitment Therapy?
ACT is a form of cognitive behavioral therapy that focuses on psychological flexibility — the ability to stay present and act in line with your values even when difficult thoughts and emotions are present. Rather than treating uncomfortable feelings as problems to be removed, ACT teaches that struggling against them often makes things worse. The goal is to change your relationship with those experiences so they have less power over your behavior.
The name captures the two halves of the approach: acceptance of what is outside your control, and commitment to action that moves you toward the life you want.
The Core Principles of ACT
ACT is built around six interconnected processes that together support psychological flexibility:
- Acceptance. Making room for painful feelings rather than fighting or avoiding them.
- Cognitive defusion. Learning to step back from thoughts and see them as mental events, not literal truths or commands.
- Being present. Practicing mindful awareness of the here and now.
- Self-as-context. Recognizing a stable sense of self that observes experiences without being defined by them.
- Values. Clarifying what truly matters to you.
- Committed action. Taking concrete steps guided by those values, even in the presence of discomfort.
How Does ACT Work?
In ACT, a therapist helps you notice the ways you may be struggling against your own thoughts and feelings — and how that struggle can keep you stuck. Through exercises, metaphors, and mindfulness practices, you learn to "unhook" from unhelpful thoughts and to make space for difficult emotions rather than letting them dictate your choices. At the same time, you identify your core values and set goals and actions that align with them. The emphasis is less on feeling better in the moment and more on living well even when difficult feelings are present.
How is ACT different from traditional CBT?
Traditional CBT often focuses on identifying and changing or challenging distorted thoughts. ACT takes a different stance: rather than disputing thoughts, it helps you change your relationship to them — accepting their presence while choosing values-based action anyway. Both are part of the cognitive behavioral family and both are effective; ACT simply emphasizes acceptance and values over symptom reduction.
What Does ACT Treat?
ACT has been studied and used for a wide range of concerns, including depression, anxiety disorders, chronic pain, stress, OCD, and substance use issues. It can also help people who are not facing a specific diagnosis but feel stuck, unfulfilled, or overwhelmed by difficult emotions. Because it focuses on psychological flexibility rather than one specific problem, its principles apply broadly.
What to Expect From ACT
ACT sessions tend to be active and experiential. Rather than only talking about problems, you can expect to do exercises, try mindfulness practices, and explore metaphors that make the concepts concrete. Your therapist will help you clarify your values and translate them into specific, doable actions between sessions. Many people find ACT refreshing because it does not require you to "fix" or get rid of every difficult thought before you can move forward with your life.
