Acceptance and Commitment Therapy (ACT, pronounced as the word "act") sits in the same family as CBT but takes a notably different stance toward distressing thoughts and feelings. Rather than trying to reduce or dispute them, ACT focuses on changing the relationship a person has with their inner experience — and on building a life that moves toward what matters even when symptoms are present. For psychosis, this is a meaningful shift.
ACT for psychosis teaches people to notice voices and unusual thoughts as mental events, accept their presence without fusing with them, and take action guided by personal values.
The six processes of ACT
ACT is built around six interrelated processes, sometimes called the "hexaflex":
- Cognitive defusion — seeing thoughts as thoughts, not as literal truth.
- Acceptance — making room for difficult internal experience without struggling to push it away.
- Contact with the present moment — mindful awareness of what is happening now.
- Self as context — noticing the part of you that observes experience and is not defined by it.
- Values — clarifying what truly matters to you in life.
- Committed action — taking concrete steps in those valued directions.
How ACT applies to voices and delusions
Traditional CBTp for voices often works by examining beliefs about the voice (its power, identity, intent) and testing them. ACT takes a slightly different angle: rather than arguing with the voice or its content, the person learns to notice it as a mental event, leave space for it, and continue toward what matters anyway.
For example, instead of trying to silence a voice that says "you're worthless," an ACT clinician might help the person notice the voice, say something like "thanks, mind, for that thought," and continue with the activity they value. The voice may stay; the person's relationship to it changes.
Defusion techniques
Defusion is one of the most useful ACT skills for psychosis. Common techniques include:
- Naming the thought — "I'm having the thought that I am being watched."
- Repeating a word — saying a distressing word aloud over and over until it loses semantic weight.
- Singing the thought — putting the voice's words to a melody.
- Thanking the mind — a brief, light acknowledgement.
- Leaves on a stream — visualising thoughts floating past on a stream rather than being grabbed and pulled in.
Values and committed action
Symptoms can pull people toward narrow, defensive lives — staying inside, avoiding places where voices spike, withdrawing from relationships. ACT pushes back gently by asking: what kind of life do you want? What do you want to stand for? Values work in ACT identifies domains (relationships, work, health, creativity, community) and clarifies what matters in each. Committed action then takes small, concrete steps in those directions, even when symptoms are present. This can dovetail with the goals of CBTp for negative symptoms and behavioural activation.
The evidence base
ACT has accumulated a respectable evidence base for psychosis. Bach and Hayes published one of the first trials in 2002 in the Journal of Consulting and Clinical Psychology, finding that brief ACT reduced rehospitalisation rates compared with treatment as usual. A subsequent randomised trial by Gaudiano and Herbert (Behaviour Research and Therapy, 2006) found similar benefits for inpatients with psychotic symptoms. More recent meta-analyses, including work by Cramer and colleagues in Schizophrenia Research, suggest small-to-moderate effects on hospitalisation, distress, and functioning. The evidence is not as deep as for CBTp, but it is consistent and growing.
What a session looks like
ACT sessions are usually weekly or fortnightly, often 8 to 16 sessions for psychosis. They are experiential — full of metaphors, exercises, and brief mindfulness practices — rather than purely talk-based. Common metaphors include:
- The passengers on the bus (your symptoms are passengers; you are still the driver going where you want to go)
- Quicksand (struggling sinks you faster; relaxing into it lets you find solid ground)
- The chess board (you are the board, not the pieces fighting on it)
Adaptations for psychosis
- Concrete, repeated examples instead of abstract philosophy
- Short mindfulness practices, often eyes-open
- Careful pacing during periods of acute symptoms
- Explicit safety planning if voices include commands
Voices are commanding harm to yourself or others, you are feeling overwhelmed, or you cannot use the skills to step back from urges. Contact your treatment team or call 988.
Who tends to benefit
- People exhausted by years of trying to argue with or eliminate voices
- People with strong values who feel stuck in symptom management
- People who responded only partially to traditional CBTp
- People whose psychosis is intertwined with experiential avoidance and trauma
How to access ACT
The Association for Contextual Behavioral Science maintains a clinician directory. Some psychosis-specialist clinics now train staff in ACT alongside CBTp. Self-help workbooks adapted for psychosis include ACT for Psychosis Recovery by Morris, Johns, and Oliver.
The big picture
ACT does not promise that voices or unusual beliefs will go away. It promises something subtler and arguably more durable: that a meaningful life is possible while symptoms continue. For many people, that reframe is what unlocks recovery — not the absence of distress, but a different relationship to it.
