The short version
- •ACT (said as one word, "act") is an evidence-based therapy in the CBT family that aims to build psychological flexibility — the ability to stay present, open up to difficult inner experiences, and act on your values even when it is hard.
- •Rather than trying to eliminate or argue with painful thoughts and feelings, ACT teaches you to change your relationship with them so they have less control over your behavior.
- •Its core processes include acceptance, cognitive defusion (unhooking from thoughts), present-moment awareness, perspective-taking, clarifying values, and committed action.
- •ACT is used across depression, anxiety, chronic pain, OCD, and stress, and is particularly useful when struggling against symptoms has itself become part of the problem.
- •Meta-analyses support ACT as an efficacious treatment, broadly comparable to established treatments like CBT for many conditions.
- •ACT pairs naturally with ketamine: its acceptance and values work helps patients meet, rather than fight, what arises during sessions and translate insight into committed action afterward.
What it is
Acceptance and commitment therapy is a behavioral therapy whose central goal is psychological flexibility: the capacity to be present, to allow difficult thoughts and feelings without being controlled by them, and to keep moving toward what matters to you. ACT departs from classic CBT in an important way — instead of focusing primarily on changing the content of distorted thoughts, it focuses on changing a person's relationship to their thoughts and feelings. It rests on six interrelated processes: acceptance (making room for unwanted inner experiences rather than fighting them), cognitive defusion (seeing thoughts as thoughts rather than literal truths or commands), contact with the present moment, self-as-context (a flexible perspective on oneself), values (clarifying what genuinely matters), and committed action (taking values-guided steps even in the presence of discomfort). The premise is that much suffering comes not from pain itself but from the struggle to avoid or control it — and that a life of meaning is built by accepting unavoidable pain while acting on values.
What it helps with
Helps when fighting anxiety has become its own problem; shifts the goal from eliminating anxiety to living well alongside it.
An evidence-based alternative or complement to CBT, with a focus on values-driven behavioral re-engagement.
Strong fit — ACT reduces pain-related disability by changing the struggle with pain rather than requiring pain itself to decrease.
Used alongside exposure work; acceptance and defusion help patients tolerate distressing intrusive thoughts without compulsions.
What to expect
Experiential, not just talk
ACT uses metaphors, mindfulness exercises, and in-session experiential work — you practice new ways of relating to thoughts and feelings, not just discuss them.
Values at the center
Early work clarifies what genuinely matters to you, and the rest of therapy is organized around acting on those values despite discomfort.
Acceptance over control
Rather than techniques to get rid of anxiety or sadness, you learn to make room for them so they stop running the show.
Flexible length
Can be brief and focused or longer-term; often comparable in length to CBT, and deliverable individually or in groups.
The evidence
ACT is an empirically supported therapy with a substantial and growing evidence base. A meta-analysis of its efficacy (A-Tjak 2015) found ACT effective across a range of problems — including anxiety, depression, and somatic and chronic-pain conditions — and broadly comparable to established treatments such as traditional CBT. It is recognized as an evidence-based practice and is particularly valued for conditions where acceptance and values-based action are more useful targets than symptom elimination, such as chronic pain.
How it pairs with ketamine
ACT and ketamine fit together unusually well. A ketamine session frequently brings up powerful thoughts, feelings, and shifts in perspective; ACT's core skills — acceptance, defusion, present-moment awareness — are exactly what help a person meet that material openly rather than brace against it, and its emphasis on values and committed action helps translate post-session insight into real behavior change. The acceptance stance also reduces the fear of the dissociative experience itself. Tovani's integration philosophy aligns closely with ACT: the point of treatment is not only symptom relief but re-engaging with a meaningful life, and ACT provides a concrete framework for doing so alongside ketamine.
Frequently asked
How is ACT different from CBT?
Classic CBT focuses largely on identifying and changing distorted thoughts; ACT focuses on changing your relationship to thoughts and feelings — accepting them rather than fighting them — and on taking action guided by your values. Both are evidence-based and in the same broad family; ACT is especially useful when the struggle against symptoms has itself become the problem.
Does "acceptance" mean giving up?
No. In ACT, acceptance means stopping the exhausting, often counterproductive struggle to control or eliminate unavoidable inner pain — so your energy goes into living by your values instead. It is the opposite of resignation: it frees you to act meaningfully even while difficult feelings are present.
What conditions is ACT good for?
ACT has evidence across depression, anxiety, OCD, stress, and especially chronic pain, where reducing the struggle with pain lowers disability even when pain intensity does not change. It is a good fit whenever acceptance and values-driven action are more useful than trying to eliminate symptoms.
Why does ACT pair well with ketamine?
Ketamine sessions often surface intense thoughts, feelings, and shifts in perspective. ACT's skills — acceptance, unhooking from thoughts, present-moment awareness, and values-based action — help you meet that material openly and turn post-session insight into real change, which fits Tovani's integration-focused approach.
