ACT and Trauma

What is trauma?

Trauma is not just about what happened. It is about what the mind and body had to do to cope with what happened.

When an experience feels overwhelming – physically or emotionally – and there isn’t enough support to process it at the time, it can leave a lasting imprint. This might be a single event, or something that happened repeatedly over time. It might involve clear threat or harm, or something quieter, like not feeling seen, safe, or emotionally held.

Trauma can disrupt a person’s sense of safety, trust, and control. It can show up in many different ways – intrusive thoughts, anxiety, emotional overwhelm, or a sense of disconnection. Some people feel constantly on edge. Others feel numb, flat, or distant from themselves and others.

Not everyone who experiences a difficult event will experience trauma in the same way. It depends on many factors, including support, environment, and what was needed but missing at the time.

Trauma and PTSD: What’s the difference?

Trauma and PTSD are related, but they are not the same.

Trauma refers to the impact of an overwhelming experience on the nervous system. It can affect thoughts, emotions, the body, and relationships. These responses might be immediate, or they may appear much later.

PTSD (post-traumatic stress disorder) is a specific pattern of symptoms that can develop after trauma. This may include re-experiencing the event through flashbacks or nightmares, avoiding reminders of what happened, feeling persistently on edge, or noticing changes in mood and thinking.

Not everyone who experiences trauma develops PTSD. In practice, many people are living with the effects of trauma without having a formal diagnosis. This often shows up in ways that feel less obvious – relationship difficulties, rumination, anxiety, low self-worth, or a sense of feeling stuck.

Different forms of trauma

Trauma can take different forms, and understanding this can help make sense of present-day patterns.

Acute trauma refers to a single overwhelming event, such as an accident or loss.

Chronic trauma involves repeated exposure over time, such as ongoing stress, abuse, or instability.

Complex trauma often develops through repeated experiences in close relationships, particularly in childhood. This might include emotional neglect, inconsistency, or not feeling safe or understood. This type of trauma can have a deep impact on identity, relationships, and emotional regulation.

There can also be indirect forms of trauma, where someone is affected by witnessing or supporting others through distressing experiences.

What matters most is not the category, but the impact. Two people can go through similar experiences and be affected in very different ways.

How trauma can show up

Trauma often lives on in the present, even when the past is long gone.

It can show up as intrusive thoughts or memories, or as a strong urge to avoid anything that might trigger those feelings. There may be anxiety, irritability, or difficulty sleeping. Some people feel constantly alert, as though something bad might happen at any moment.

Others experience a deep sense of disconnection – from their emotions, their body, or other people.

There can also be patterns that are harder to link directly to trauma. Struggling with boundaries. Feeling responsible for others. Repeating the same relationship dynamics. A persistent sense of shame, or a belief that something is wrong.

From a trauma-informed perspective, these responses make sense. They are ways the system has learned to cope and stay safe.

Can ACT help with trauma?

Acceptance and Commitment Therapy (ACT) is not a trauma-specific therapy, but it can be a valuable and effective way of working with the impact of trauma.

Rather than focusing on removing difficult thoughts or feelings, ACT supports a different relationship with them.

One of the key elements is mindfulness – developing the ability to notice thoughts, emotions, and bodily sensations in the present moment. For someone who has experienced trauma, this can help create space between what is happening now and what has happened before.

Acceptance is another important part. This does not mean liking or agreeing with what has happened. It means gently making space for difficult internal experiences, rather than pushing them away or becoming overwhelmed by them. This can reduce the cycle of avoidance and emotional build-up.

ACT also works with cognitive defusion, which involves stepping back from unhelpful thoughts. Trauma can leave behind powerful beliefs – such as “I’m not safe” or “There’s something wrong with me”. Defusion helps loosen the grip of these thoughts, so they are no longer taken as absolute truth.

A central part of ACT is values. Trauma can pull someone away from what matters to them, narrowing life down to survival. Reconnecting with values can bring a sense of direction, helping a person move towards relationships, activities, and ways of living that feel meaningful.

This links closely with committed action – taking small, manageable steps towards that kind of life, even in the presence of fear or uncertainty.

A flexible, trauma-informed approach

In practice, trauma does not always present as a clear diagnosis.

More often, it shows up in the background – through relationship struggles, anxiety, insomnia, shame, or a sense of being stuck. ACT can be adapted to work with all of these experiences in a way that feels manageable and grounded.

A trauma-informed use of ACT pays close attention to safety.

It recognises the importance of working with both the mind and the body. At times, the focus may be on bodily awareness – helping someone reconnect with physical sensations in a way that feels safe. At other times, the work may focus more on thoughts, emotions, and values.

This flexibility means the work can be tailored to each individual, rather than following a fixed process.

It can also be integrated with other approaches, such as somatic work or Lifespan Integration, depending on what is needed.

Moving towards healing

Healing from trauma is not about getting rid of thoughts, emotions, or parts of the self.

It is about developing a different relationship with them.

Over time, this can lead to less avoidance, less rumination, and a greater sense of choice. There may be more capacity to stay present, to respond rather than react, and to move towards what feels important.

For many people, this also brings a growing sense of self-understanding and self-compassion.

The past may still be part of the story, but it no longer defines the present in the same way.

With the right support, it becomes possible to feel more grounded, more connected, and more able to build a life that feels meaningful and aligned.
