Acceptance and Commitment Therapy (ACT) for Addiction Recovery

Acceptance and Commitment Therapy (ACT) is a third-wave behavioural therapy that pairs well with addiction recovery because it stops trying to win an argument with your own internal experience. Instead of changing distressing thoughts, ACT teaches you to accept that cravings, anxiety, and sadness will keep showing up, then commit to actions aligned with your values regardless. A meta-analysis of ten randomised trials found a small-to-medium effect for ACT on substance use outcomes compared with active treatments (Lee et al., Drug Alcohol Depend, 2015). It tends to be a better fit than standard CBT when chronic mood problems, persistent anxiety, or values confusion are part of the picture.

What Is Acceptance and Commitment Therapy?

ACT is a behavioural psychotherapy developed by Steven Hayes, Kirk Strosahl, and Kelly Wilson that treats psychological flexibility — the ability to stay present and act on your values even when uncomfortable thoughts and feelings show up — as the core skill of mental health (Hayes et al., Behav Ther, 2011). It is delivered in individual or group sessions and uses experiential exercises and metaphors rather than thought-challenging worksheets.

The name signals the method. You accept internal experiences you cannot reliably control — cravings, sadness, anxious thoughts, memories — instead of fighting them. You commit to behaviour aligned with what you actually want your life to be about. The “T” is just therapy. It is said as the word “act,” and that’s intentional: the whole model is about action.

ACT is part of what clinicians call the third wave of behavioural therapy, alongside DBT and other mindfulness-based approaches. Where classical CBT often tries to dispute or restructure unhelpful thoughts, ACT changes your relationship with those thoughts. The thought “I need a drink right now” can be there, loudly, and you can still pour the coffee and drive to work.

Why Does ACT Work for Addiction?

ACT works for addiction because addiction is, in a significant way, an experiential avoidance strategy. People drink, use, or act out to not feel something — boredom, anxiety, shame, grief, withdrawal. ACT targets the avoidance pattern itself by teaching people to make room for the uncomfortable feeling without acting on it. A residential study found that experiential avoidance and low distress tolerance correlated strongly with substance cravings (Shorey et al., J Addict Dis, 2017).

If you have been in active addiction, you already know the pattern. A bad feeling shows up. The thought “I can’t sit with this” follows. The substance arrives. The feeling goes away for a few hours. The feeling comes back stronger. Repeat. ACT doesn’t try to make the bad feeling smaller — it teaches you to be with it without using.

This is also why ACT lines up well with the work people do in relapse prevention. Triggers are not the problem. The internal experience the trigger sets off is the problem, and your inability or unwillingness to sit with it is what tips you into use. Teach the willingness, and the trigger loses most of its power.

What Are the Six Core Processes of ACT?

ACT is built on six interlocking processes, sometimes drawn as a hexagon called the “hexaflex.” Each one targets a different part of psychological flexibility. They are not phases you graduate through — they are skills you practise in rotation, and each can become the way back in when one of the others stalls.

The two ends of the model are the ones that do most of the work in early recovery. Acceptance gives you somewhere to put the feelings. Committed action gives you somewhere to put your hands and feet. The four in the middle are the skills that make both possible.

How Is ACT Different from CBT?

The core difference is the target. Traditional CBT often tries to change the content of distressing thoughts — challenge them, test them, replace them. ACT changes your relationship to the thought without trying to change the thought itself. A 2015 meta-analysis of 39 trials found ACT outperformed control conditions across mental and physical health problems, and performed comparably to established CBT approaches (A-Tjak et al., Psychother Psychosom, 2015).

The honest answer to “which one is better?” is: it depends on the person. Both work. Most clients in residential treatment will get elements of both, plus motivational interviewing, plus group work. What ACT adds is a way forward when the CBT premise — change the thought, change the behaviour — feels like one more thing the person can’t seem to do.

The clients I see who get the most out of ACT are usually the ones who have done CBT before and described it as “useful but exhausting.” When you’ve spent years trying to argue with your own thoughts and still feel like you’re losing, the permission to stop arguing — to let the thought be there and still do the thing — is a relief. That relief itself is therapeutic.

Why Does ACT Suit Chronic Depression Plus Addiction?

ACT suits chronic depression plus addiction because it doesn’t require the depression to lift before life can move. Many people with long-standing depression and a substance use disorder have already tried — through medication, therapy, or both — to make the depression smaller and failed. ACT lets them act on their values while the depression is still present, which often loosens its grip more than fighting it ever did.

If you are in this group, you already know the trap. The plan is: get the depression down, then build a life. The depression doesn’t go down. The life doesn’t get built. The substance fills the gap. ACT inverts the order. You don’t have to feel better to do the thing you care about. You do the thing you care about, and feeling sometimes follows.

This is one reason ACT shows up so often in personalised dual diagnosis treatment plans. When someone is carrying depression, anxiety, or trauma and a substance use disorder, the standard “fix the mental health first, then deal with the using” sequence often stalls. ACT lets the work proceed in parallel.

The same logic applies to chronic anxiety. You don’t have to stop being anxious to live a meaningful life. You have to stop letting anxiety pick your behaviours. ACT teaches exactly that distinction.

What Are the Practical Techniques in ACT?

ACT relies heavily on experiential exercises and metaphors rather than psychoeducation alone. The point is to feel the shift, not to understand it intellectually. Most of these can be introduced in a session and practised between sessions, which is what makes them stick in a residential setting where you’re seeing the therapist multiple times a week.

• The “I’m having the thought that…” technique. Instead of “I need a drink,” say “I’m having the thought that I need a drink.” Then “I’m noticing that I’m having the thought that I need a drink.” Each layer puts a little space between you and the thought. Used dozens of times a day in early recovery.
• The bus passengers metaphor. You are the driver of your life’s bus. Your difficult thoughts, memories, and feelings are passengers. They can shout, threaten, and demand you turn around. You can hear them and keep driving toward the destination that matters to you.
• The chessboard metaphor. You are not the white pieces fighting the black pieces. You are the board that holds all of them. The pieces will keep fighting. The board doesn’t have to win the war for the game to keep going.
• Values cards. A deck of words — honesty, family, creativity, health, service — sorted by what actually matters to you. You then design weekly committed actions that move you toward those values, regardless of mood.
• Present moment grounding. Short mindfulness exercises (often two to five minutes) to step out of rumination and back into the room. Especially useful during cravings.
• Defusion through repetition. Saying a difficult word out loud thirty times until it stops meaning what it usually means. Sounds silly. Works.

None of this is magic. It is repetition. You practise it during stable moments so it is available when a craving or a low mood arrives. That’s why residential treatment is often where ACT gets its strongest foothold — you have the structure to practise it every day.

Where Does ACT Fit Inside Residential Treatment?

Inside residential treatment, ACT usually sits alongside CBT, DBT, motivational interviewing, and group work as one of the modality choices — not as a replacement for them. A pilot RCT comparing ACT and CBT for methamphetamine use disorder found both produced comparable outcomes, with no single approach winning across all measures (Smout et al., Subst Abus, 2010). What that means in practice: the modality is matched to the person.

The clients most often matched to an ACT-focused track include people with:

• Chronic depression or persistent low mood alongside the substance use
• A history of CBT that helped but left a gap
• Long-standing anxiety they can’t reason their way out of
• Significant values confusion — “I don’t know what I’m doing this for”
• Trauma where avoidance is the dominant survival strategy (often used with other dual diagnosis therapies)

For clients whose main work is around skill-building and impulse control, DBT is often a closer fit. For clients with clearly identifiable cognitive distortions, classical CBT does the job. ACT is the option when the work isn’t about fixing the thought, it’s about getting your life back while the thought keeps showing up.

How Does One Step Use ACT in Its Programme?

One Step uses ACT as one of the therapy modalities offered inside an individualised plan, not as a fixed protocol every client follows. After assessment, our therapists match each client to the combination of approaches most likely to fit — typically ACT alongside CBT, DBT, motivational interviewing, and group work as part of our structured treatment programme. Programme fee is ฿280,000/month (~$8,500 USD), set out in full on the pricing page.

Clients we typically match to an ACT-heavier therapy plan include those with chronic mood problems sitting underneath their substance use, those who have already tried CBT and found it useful but not sufficient, and those carrying persistent values confusion about what they want recovery to be for. The work usually shows up in individual therapy sessions, with reinforcing exercises across the week — defusion practice during cravings, present-moment grounding before group, values-based goal-setting in your individual sessions.

What this looks like day to day, inside our weekly schedule: morning mindfulness slots double as present-moment training, group therapy is where you practise defusion in real time when difficult content comes up, and one-to-one sessions are where values clarification and committed action plans get built. Skills get reinforced through outdoor and experiential activities — kayaking, hiking, and gym time create real-world moments to practise willingness when discomfort shows up.

ACT continues to be useful after residential treatment, often more than CBT does. The skills are general-purpose. Defusion works on a craving thought, an angry thought, an “I’m worthless” thought. Values keep working when the structure of rehab disappears. We build practice into the aftercare plan so clients leave with something portable, not just a set of CBT worksheets.
