ACT therapy

What is ACT?

Acceptance and commitment therapy is a modern form of behavioural therapy rooted in the science of human language and cognition. Unlike approaches that focus on reducing or controlling difficult thoughts and emotions, ACT works from the premise that struggling against painful internal experiences often makes things worse. Instead, it teaches you to make room for these experiences while redirecting your energy towards what genuinely matters to you.

This may sound counterintuitive at first. Most of us have learned that the way to feel better is to get rid of bad feelings. But ACT recognises that many of the strategies we use to avoid or suppress difficult emotions, such as withdrawing from social situations, overworking, ruminating, or numbing ourselves, end up narrowing our lives and creating additional problems. ACT offers a different path: rather than waiting until the difficult feelings go away before you start living, you learn to carry them with you while moving towards the life you want.

At its core, ACT develops six interrelated skills, often referred to as psychological flexibility:

• Present-moment awareness, learning to be fully engaged with what is happening right now rather than being lost in worries about the future or regrets about the past.
• Defusion, stepping back from unhelpful thoughts rather than being caught up in them. This does not mean ignoring your thoughts, but recognising that a thought is just a thought, not a command or a fact.
• Acceptance, making room for difficult feelings, urges and sensations without trying to fight or avoid them.
• Self-as-context, developing a stable sense of self that is separate from your thoughts and feelings. You are the person having the experiences, not the experiences themselves.
• Values clarification, getting clear on what truly matters to you, the qualities you want to bring to your life and relationships.
• Committed action, taking concrete steps towards your values, even when it feels uncomfortable to do so.

ACT draws on mindfulness principles without requiring formal meditation practice. It uses a range of experiential exercises, metaphors and behavioural techniques to help you build a richer, more meaningful life, even in the presence of pain or difficulty.

When it helps

ACT has a growing evidence base across a wide range of psychological difficulties, including:

• Chronic anxiety and worry
• Depression and persistent low mood
• Chronic pain and long-term health conditions
• Stress and burnout
• Grief and loss
• Obsessive compulsive difficulties
• Social anxiety
• Perfectionism and self-criticism
• Adjustment to life transitions
• Low self-esteem and lack of direction

ACT can be particularly helpful when you feel stuck in patterns of avoidance, when previous attempts to control your thoughts and feelings have not worked, or when you have lost touch with what matters most to you. It tends to resonate strongly with people who have tried to think their way out of their difficulties and found that the more they analyse and ruminate, the worse things become.

It is also well suited to situations where the source of your distress cannot simply be removed. If you are living with a chronic health condition, navigating grief, adjusting to a major life change, or facing ongoing stress that cannot easily be resolved, ACT helps you find ways to live well alongside the difficulty rather than putting your life on hold until it passes.

What to expect

ACT sessions are collaborative and often experiential. Rather than simply talking about difficulties, your psychologist may guide you through exercises designed to shift how you relate to your inner world. This is what makes ACT distinctive: it is not just about understanding your patterns intellectually, but experiencing new ways of responding to them in the room.

For example, your psychologist might use a metaphor like “passengers on the bus” to explore how you relate to difficult thoughts. In this exercise, you are the driver of the bus, and your anxious or self-critical thoughts are noisy passengers shouting instructions from the back. The question becomes: who is actually driving? You might also practise brief mindfulness exercises, work through values sorting activities, or explore what happens when you make space for a difficult feeling rather than pushing it away.

Early sessions typically focus on understanding your current patterns, particularly any cycles of avoidance or control that may be keeping you stuck. Your psychologist will be curious about what you have already tried and what has not worked, not to judge those strategies, but to understand the trap you are caught in. From there, the work moves towards building skills in defusion, acceptance and present-moment awareness, alongside identifying and clarifying your core values.

Values work is central to ACT and often proves to be one of the most powerful parts of therapy. Many people discover that they have been so focused on managing their symptoms that they have lost sight of what they actually want their life to be about. Clarifying your values provides a compass for decision-making and a motivation for change that goes deeper than symptom reduction.

Between sessions, you will be encouraged to practise new skills and experiment with values-based actions in your daily life. These might be small, specific steps, such as having a difficult conversation you have been avoiding, or showing up to a social event despite feeling anxious. The point is not to do these things perfectly, but to practise willingness and to notice what happens when you move towards what matters rather than away from what hurts.

Therapy is usually delivered weekly, and most people benefit from 8 to 16 sessions, though this depends on the complexity of your difficulties. Some people find that a shorter course of ACT gives them the tools they need, while others benefit from longer-term work, particularly if the patterns of avoidance are deeply ingrained.

The evidence for ACT

ACT has a substantial and growing evidence base. It is classified as an empirically supported treatment for a range of difficulties, and the number of published randomised controlled trials has increased significantly over the past decade.

Research supports ACT’s effectiveness for chronic pain, depression, anxiety disorders, OCD, substance misuse, stress in the workplace and adjustment to long-term health conditions. A key finding across many studies is that ACT works through its proposed mechanism of change, psychological flexibility, rather than through symptom reduction per se. In other words, people improve not because they stop having difficult thoughts and feelings, but because they develop a different relationship with those experiences and become more able to act in line with their values.

NICE currently recommends ACT as an option within the broader CBT family for several difficulties, and it is increasingly offered within NHS services.

Comparisons between ACT and traditional CBT generally find that both approaches produce similar outcomes, but they appear to work through different mechanisms. For some people, the ACT framework feels more intuitive and resonant than the cognitive restructuring approach used in standard CBT, particularly if they have found thought-challenging exercises unhelpful or frustrating in the past.

Online delivery of ACT is well supported by the evidence. The experiential and metaphor-based nature of ACT translates effectively to video sessions, and several studies have demonstrated that online ACT programmes produce outcomes comparable to face-to-face delivery.

ACT at The Online Psychologists

At The Online Psychologists, ACT is delivered by HCPC-registered clinical psychologists who have specialist training in acceptance and commitment therapy. Our psychologists integrate ACT with their broader clinical expertise, meaning they can draw on other evidence-based approaches when appropriate while keeping the ACT framework at the centre of your work together.

Our matching process pairs you with a psychologist who has experience working with your specific difficulties. Whether you are seeking help for burnout, chronic anxiety, grief or another issue, we will match you with someone who understands both the condition and how ACT applies to it.

Sessions are typically 50 minutes and held weekly, moving to fortnightly as you build confidence in applying the skills independently. Your psychologist will work with you to set clear goals for therapy while remaining open to what emerges. ACT is a flexible approach, and the pace and focus of sessions will be guided by what is most useful for you.

Online delivery works particularly well for ACT. The experiential exercises and mindfulness-based components translate naturally to video sessions, and many clients find it helpful to practise these techniques in the environment where they will actually be using them. Being at home can also make it easier to drop into a reflective, open state, which supports the kind of present-moment awareness that ACT cultivates.

Frequently asked questions

Is ACT the same as mindfulness-based therapy? ACT uses mindfulness as one of its core components, but it is not a mindfulness-based therapy in the way that MBSR or MBCT are. In ACT, mindfulness is woven into the broader framework of psychological flexibility alongside values work, defusion and committed action. You do not need any previous experience of mindfulness or meditation to benefit from ACT.

What if I do not know what my values are? This is very common, and it is one of the things ACT is specifically designed to help with. Many people come to therapy feeling disconnected from what matters to them, particularly if they have been in survival mode for a long time. Values clarification is a guided process, not something you need to arrive with already figured out. Your psychologist will use exercises and conversation to help you explore and identify your values at a pace that feels right.

How is ACT different from CBT? Both ACT and CBT are evidence-based therapies within the broader cognitive behavioural tradition, but they differ in emphasis. CBT tends to focus on changing the content of unhelpful thoughts, helping you evaluate whether they are accurate and develop more balanced alternatives. ACT focuses on changing your relationship with thoughts, helping you hold them more lightly rather than buying into them or fighting them. Your psychologist can help you work out which approach is likely to be the better fit for you.

Can ACT help if I have tried other therapies before? Yes. ACT is often particularly helpful for people who have had previous therapy, especially if they found that insight alone did not lead to lasting change, or if strategies for controlling their thoughts and feelings provided only temporary relief. ACT offers a fundamentally different approach, one that focuses on living well alongside difficulty rather than eliminating it.
