Acceptance and Commitment Therapy (ACT): Core Concepts

Acceptance and commitment therapy—usually said as one word, “act”—is a form of talk therapy that takes an unusual stance toward difficult thoughts and feelings. Instead of trying to eliminate or argue with them, ACT teaches you to make room for them while steering your actions toward what matters to you. Its aim is not to feel good at all times, but to live well even when uncomfortable feelings are present.

ACT is part of the broader family of cognitive and behavioral therapies. This guide explains its core concepts, what the research supports, what a session looks like, and how to find a licensed provider.

What ACT is

The central goal of ACT is psychological flexibility: the ability to stay present, open up to your experience, and do what matters even when it is hard. Where some approaches focus on changing the content of thoughts, ACT focuses on changing your relationship to them—noticing a worry as “just a thought” rather than a command you must obey.

ACT organizes this into six interlocking skills:

What the research supports

Research supports the use of ACT for several conditions, including anxiety, depression, and chronic pain, with a growing body of studies in areas such as stress, obsessive-compulsive presentations, and coping with long-term illness. The American Psychological Association recognizes ACT among evidence-based therapies, and Cochrane and other reviewers have examined it across mental-health and pain settings, often finding it comparable to other active treatments while noting that evidence quality varies.

It is worth being realistic: ACT is not a cure, and results differ from person to person. For some concerns the evidence is strong; for others it is still emerging. Whether ACT suits you—on its own or alongside other care—depends on your goals and diagnosis, which is a good conversation to have with a clinician.

What a session looks like

ACT sessions typically run about 45 to 60 minutes and can be brief or extend over several months, depending on your needs. Rather than only talking about problems, ACT is experiential: your therapist may use metaphors, mindfulness exercises, and short practices to help you experience defusion or acceptance rather than just understand them intellectually.

A common thread is values work. Early on, you might explore what you want your life to stand for—relationships, health, creativity, contribution. Later sessions connect those values to specific, doable actions, and use acceptance and defusion skills to handle the discomfort that shows up along the way. Practice between sessions is usually part of the process.

How to find a licensed provider

ACT is delivered by licensed mental-health professionals, including clinical psychologists, licensed professional counselors, and clinical social workers who have trained in the approach. Because ACT is a specific method, it is reasonable to ask a prospective therapist whether they practice it and with what kinds of concerns.

You can find providers through your primary care clinician, your insurance directory, professional-association finders such as the American Psychological Association’s, and community or university clinics. If you are comparing approaches, our interpersonal therapy explainer covers a relationship-focused option, and our family therapy guide describes work that involves more than one person.

When to seek help

Consider reaching out if anxiety, low mood, avoidance, or ongoing pain is interfering with your daily life, relationships, or ability to do things you care about, especially if it has lasted more than a couple of weeks. Earlier support generally makes treatment more manageable.

If you are in crisis—having thoughts of suicide or self-harm, or worried about someone who is—call or text 988 (the Suicide and Crisis Lifeline in the US) or go to your nearest emergency department. ACT is for ongoing care, not emergencies.

Frequently asked questions

Is ACT a type of CBT? It grew out of the cognitive-behavioral tradition but differs in emphasis: ACT focuses on accepting thoughts and acting on values rather than changing thought content.

Does ACT mean giving up on feeling better? No. It aims for a fuller life; mood often improves as a byproduct, but the goal is workable action, not the absence of discomfort.

How long does it take? It varies—some people do brief courses, others work over several months.

Can ACT help with chronic pain? Research supports its use for coping with chronic pain, often by improving function and quality of life rather than removing pain itself.

Is mindfulness the same as ACT? Mindfulness is one ingredient in ACT, but ACT also emphasizes values and committed action.

Can it be done online? Many clinicians offer ACT by video; ask whether telehealth fits your situation.
