Acceptance and Commitment Therapy (ACT, pronounced as one word) is an evidence-based therapy that helps clients build psychological flexibility: the ability to be present with whatever is showing up internally while moving toward what matters most. ACT uses six core processes and has strong research support for anxiety, depression, chronic pain, OCD, burnout, and many other presentations. ACT was developed in the 1980s and 1990s by Steven Hayes and colleagues. It is part of the "third wave" of behavioural therapies, alongside DBT and Mindfulness-Based Cognitive Therapy. ACT integrates acceptance and mindfulness with commitment to values-based action. Much of human suffering comes from the struggle against internal experience: trying not to feel anxious, trying not to think distressing thoughts, trying to control what cannot be controlled. The struggle itself often makes things worse. ACT teaches a different relationship with internal experience: notice it, accept it, defuse from it, and move toward what you value anyway. ACT sessions often use experiential exercises, metaphors, and mindfulness practices alongside conversation. The therapist may guide the client through defusion exercises (creating distance from sticky thoughts), values clarification activities, or present-moment awareness practices. Homework often involves committed action steps between sessions. ACT is often briefer than long-arc depth therapy. Typical treatment runs 8 to 16 sessions for many presentations, though work can extend depending on goals. ACT has strong research support across anxiety, depression, chronic pain, OCD, and many other conditions. The Association for Behavioral and Cognitive Therapies recognizes ACT as evidence-based. ACT is not about accepting that things will not change. The acceptance is about internal experience (thoughts, feelings, sensations), not about giving up on external life changes. ACT is not just mindfulness. Mindfulness is one element of a broader behavioural therapy. ACT is not anti-cognitive. It addresses cognition differently than CBT, but cognition is part of the work. For acute panic, OCD, or specific phobias, the more focused protocols (interoceptive exposure for panic, ERP for OCD, exposure for phobias) usually move faster as primary treatments, sometimes with ACT integrated. For severe dysregulation, DBT often comes first. Curio Counselling Calgary clinicians use ACT as a primary or integrated modality.
