Frequently Asked Questions About Acceptance and Commitment (ACT)
What is Acceptance and Commitment Therapy (ACT)?
ACT (pronounced as the word "act") is a modern, evidence-based form of CBT that focuses on psychological flexibility — the ability to be present with difficult thoughts and feelings without letting them dictate your behaviour, and to take action aligned with your values even in the presence of discomfort. Rather than trying to eliminate negative thoughts or feelings, ACT teaches you to change your relationship with them so they have less control over your life.
How is ACT different from traditional CBT?
Traditional CBT aims to identify and change unhelpful thoughts — replacing distorted thinking with more balanced thinking. ACT takes a different approach: rather than changing the content of your thoughts, it changes your relationship to them through defusion (learning to observe thoughts rather than being fused with them) and acceptance (making room for difficult feelings rather than fighting them). ACT also places significant emphasis on values clarification and committed action toward what matters most to you.
What conditions does ACT treat?
ACT has a strong evidence base across a wide range of conditions including anxiety, depression, OCD, chronic pain, substance use, eating disorders, PTSD, and workplace stress. It is particularly well-suited for people who have already tried to "think their way out" of mental health struggles without lasting success, and for chronic conditions where eliminating distress is not possible but improving quality of life is. ACT is also widely used for general personal growth and resilience building.
What does an ACT session involve?
ACT sessions use a combination of experiential exercises, metaphors, mindfulness practices, and values exploration. Common exercises include defusion techniques (creating distance from unhelpful thoughts, such as noticing "I'm having the thought that..."), acceptance practices (making room for difficult feelings without struggling against them), and values clarification (identifying what matters most and what you want your life to stand for). ACT is experiential rather than lecture-based — the work happens through doing, not just discussing.
How many ACT sessions are typically needed?
ACT is often delivered over 8–16 sessions for specific conditions, though it can be shorter or longer depending on the complexity of the presentation. Many people find ACT principles continue to deepen and benefit them long after formal therapy ends because the approach provides a general framework for living — not just a set of techniques for a specific problem. Between-session practice of ACT skills in daily life is an important part of the process.
