ACT Therapy: What Is Acceptance and Commitment Therapy?

7 min read · July 9, 2026

Acceptance and Commitment Therapy (ACT) is an evidence-based psychotherapy that teaches you to accept difficult thoughts and feelings rather than fighting them, while committing to actions aligned with your values. Unlike CBT, which focuses on changing thought content, ACT focuses on changing your relationship to your thoughts. It is effective for anxiety, depression, chronic pain, OCD, and substance use. Calgary practitioners offering ACT can be found on TherapyFit.ca's directory.

ACT's core message is counterintuitive: the problem isn't your difficult thoughts and feelings. The problem is your struggle against them. The more you try to eliminate anxiety, avoid sadness, or suppress unwanted thoughts, the more power they gain over your behaviour. ACT teaches you to hold difficult internal experiences differently, with acceptance rather than resistance, while committing to actions that align with your values.

For Calgarians dealing with anxiety, chronic pain, depression, work stress, or the existential questions that come with life transitions, ACT offers a practical and philosophically grounded approach.

The Six Core Processes of ACT

ACT is built around six interconnected processes, often represented as a hexagon:

1. Acceptance

The willingness to experience difficult thoughts, feelings, and sensations without trying to change, control, or avoid them. This isn't resignation. It's making room for discomfort so that it doesn't dictate your choices. If you've been avoiding social situations because of anxiety, acceptance means being willing to feel the anxiety while still attending the event.

2. Cognitive Defusion

Changing your relationship with thoughts rather than changing the thoughts themselves. Techniques include repeating a word until it loses meaning, prefacing a thought with "I'm having the thought that..." or visualizing thoughts as leaves floating on a stream. The goal: thoughts are mental events, not facts. You don't have to obey them.

3. Present Moment Awareness

Bringing attention to the here and now rather than being caught up in rumination about the past or worry about the future. ACT uses mindfulness exercises. Not as relaxation techniques, but as skills for contacting what's actually happening in this moment.

4. Self-as-Context

Recognizing that you are not your thoughts, feelings, or roles. There's an observing self. A stable perspective from which you witness your ever-changing internal experience. This provides distance: "I notice I'm feeling anxious" rather than "I am anxious."

5. Values

Identifying what truly matters to you. Not goals (which can be achieved) but values (ongoing directions). What kind of partner do you want to be? What kind of work matters to you? How do you want to show up in relationships? Values provide compass headings for behaviour. When you know your values, you can evaluate whether your current actions are moving you toward or away from them.

6. Committed Action

Taking concrete steps toward your values, even in the presence of discomfort. This is where ACT becomes behavioural. It's not enough to identify your values. You must act on them. Committed action involves setting goals, developing action plans, and following through, using acceptance and defusion skills to handle the inevitable obstacles.

How ACT Differs from CBT

Both ACT and CBT are evidence-based, but they differ philosophically:

Aspect CBT ACT
Relationship to thoughts Challenge and change unhelpful thoughts Change relationship with thoughts (don't need to change content)
Goal regarding negative emotions Reduce frequency and intensity Accept their presence; reduce their influence on behaviour
Focus Symptom reduction Values-based living
Core mechanism Cognitive restructuring Psychological flexibility
Homework Thought records, behavioural experiments Mindfulness exercises, values clarification, committed action steps

Neither is better. They work differently and suit different people. If you respond well to logic and evidence-based reasoning, CBT may resonate. If you've tried challenging your thoughts and they keep coming back, or if you're drawn to mindfulness and meaning-making, ACT may be a better fit.

Many Calgary therapists integrate elements of both. The distinction matters less than finding an approach that works for you.

What ACT Treats

ACT has a strong evidence base for:

  • Anxiety disorders: particularly when avoidance is the primary problem
  • Depression: especially chronic or recurrent depression where cognitive approaches have plateaued
  • Chronic pain: ACT helps people live fully despite pain rather than waiting for pain to resolve
  • Work stress and burnout: values clarification helps people make career decisions aligned with what matters
  • OCD: acceptance of intrusive thoughts without compulsive responses
  • Substance use: acceptance of cravings without acting on them
  • Grief: acceptance of loss while committing to living meaningfully
  • Health anxiety: acceptance of uncertainty about health
  • Life transitions: values provide direction when everything else is uncertain

ACT is particularly effective for people who have tried to control their internal experience (fight anxiety, suppress thoughts, avoid feelings) and found that the control efforts themselves have become the problem.

What ACT Sessions Look Like

ACT sessions blend conversation, experiential exercises, and metaphor:

Values exploration. Your therapist may use structured exercises to help you identify your core values across life domains: relationships, work, health, personal growth, community. This isn't a one-time exercise; values clarification deepens throughout therapy.

Experiential exercises. Rather than just talking about acceptance, your therapist might guide you through an exercise where you sit with a difficult feeling and observe it without trying to change it. You might notice how it shifts on its own when you stop resisting.

Metaphors. ACT uses vivid metaphors: "quicksand" (struggling makes you sink faster), "unwanted party guest" (you can host a party even if anxiety shows up), "passengers on the bus" (your thoughts are passengers yelling directions, but you're still the driver). These metaphors stick and become tools you use between sessions.

Behavioural commitments. Each session typically ends with a specific committed action. A concrete step toward your values that you'll take before the next session.

Mindfulness practice. Brief mindfulness exercises are woven throughout sessions. Not as relaxation (though that may happen), but as practice in present-moment awareness.

Frequently Asked Questions

Do I have to meditate to do ACT?

No. ACT includes mindfulness exercises, but they're brief, practical, and integrated into sessions. Not extended silent meditation. If you've tried meditation apps and found them frustrating, ACT's approach to mindfulness may suit you better. The goal isn't to clear your mind; it's to notice what's happening in your mind with curiosity rather than judgment.

Is ACT saying I should just accept everything and not try to change?

No. ACT distinguishes between things you can and can't control. You can't control whether anxious thoughts show up, but you can control how you respond to them and what actions you take. Acceptance applies to your internal experience (thoughts, feelings, sensations). Committed action applies to your external behaviour. You accept the anxiety and still show up for the job interview.

How long does ACT therapy take?

ACT can be delivered in various formats, from brief interventions (4–6 sessions) to longer-term therapy (20+ sessions). For most concerns, 10–16 sessions provides a solid foundation. Some people continue longer for deeper values work and personal development. The skills you learn are meant to be practiced independently after therapy ends.

Can ACT help with relationship problems?

Yes. ACT's values work naturally extends to relationships: clarifying what kind of partner you want to be, practising acceptance of your partner's imperfections, defusing from unhelpful stories about the relationship, and committing to specific relational behaviours. Some therapists offer ACT-informed [couples work](/resources/couples-counselling-calgary). It pairs well with emotionally focused approaches.
