What Is Acceptance and Commitment Therapy (ACT)?

Acceptance and Commitment Therapy (ACT) is an evidence-based behavioral therapy that helps people develop psychological flexibility—the ability to stay present, make room for difficult experiences, and take meaningful action guided by personal values.

Quick Facts

  • ACT is pronounced as the word “act,” not the individual letters.
  • The goal is not to eliminate difficult thoughts or emotions.
  • ACT teaches skills for responding more effectively to internal experiences.
  • Psychological flexibility is the central aim of ACT.
  • ACT has been applied to anxiety, depression, OCD, trauma, chronic pain, ADHD, and many other challenges.

ACT in Simple Terms

Many people spend enormous amounts of energy trying to control, avoid, suppress, or eliminate unwanted thoughts and feelings. While these efforts are understandable, they often create additional struggle and can pull people away from the life they want to live.

ACT offers a different approach. Rather than focusing on getting rid of difficult experiences, ACT helps people learn new ways of relating to them. The emphasis shifts from controlling inner experiences to building a meaningful life guided by values.

In ACT, the question is often not, “How do I get rid of this feeling?” but rather, “How can I live well while making room for this experience?”

The Goal of ACT: Psychological Flexibility

Psychological flexibility refers to the ability to remain present, adapt to changing circumstances, and choose actions that align with personal values—even when difficult thoughts, emotions, or physical sensations are present.

Research suggests that psychological flexibility is associated with greater well-being, resilience, and life satisfaction across a wide range of situations.

In Practice

Psychological flexibility does not mean always feeling good. It means developing the ability to respond effectively to life’s challenges without becoming trapped by thoughts, emotions, or avoidance patterns.

What ACT Is Not

  • ACT is not about forcing yourself to be positive.
  • ACT is not about giving up or resigning yourself to suffering.
  • ACT is not about pretending painful experiences do not exist.
  • ACT is not about achieving perfect mental health.
  • ACT is not about controlling every thought or emotion.

Instead, ACT focuses on helping people respond more flexibly and effectively to whatever experiences arise.

Who Can Benefit from ACT?

ACT has been used with people experiencing a wide range of concerns, including anxiety disorders, OCD, depression, trauma-related difficulties, chronic pain, ADHD, perfectionism, stress, and relationship challenges.

The skills taught in ACT are not limited to mental health concerns. Many people use ACT principles to improve resilience, strengthen relationships, navigate life transitions, and pursue meaningful goals.
