Metacognitive Training (MCT) for psychosis

Metacognitive Training (MCT) for psychosis is one of the more pragmatic innovations in modern psychotherapy. Developed by Steffen Moritz and colleagues at the University of Hamburg, it is a structured group programme that targets the specific thinking biases linked to delusions and paranoia. It is also free — the materials are downloadable in more than 35 languages from the developers' website — which has helped it spread far beyond the academic centres that built it.

The premise: thinking about thinking

"Metacognition" means thinking about your own thinking — noticing how you process information, how you weigh evidence, how confident you are in your beliefs. Decades of cognitive research have identified specific biases that are more common in people with psychosis:

• Jumping to conclusions — drawing strong inferences from very limited evidence
• Bias against disconfirmatory evidence — discounting information that contradicts an existing belief
• Overconfidence in errors — feeling sure of conclusions that turn out to be wrong
• Theory of mind biases — misreading others' intentions
• Attributional biases — over-attributing negative events to others' deliberate intent
• Memory biases — confidently misremembering details
• Depressive cognitions — overgeneralised negative self-evaluations

MCT does not claim that these biases cause psychosis, but that they help maintain it — and that learning to notice them gives the person tools that complement medication and other therapies.

What a session looks like

MCT runs as a series of weekly group modules, usually 8 modules of about 45–60 minutes each, often repeated as a cycle of two parallel groups (A and B) so participants get exposure to the full curriculum. Each module focuses on one bias and uses a slide-based programme with:

• Examples from everyday life — not from psychosis
• Interactive exercises — fish-tank tasks, ambiguous pictures, social scenarios
• Group discussion
• "Take home" messages — short summaries to carry between sessions

The deliberately non-stigmatising design — using neutral examples first — is one of the things participants often appreciate. The translation to their own experiences happens organically over the course.

The evidence

MCT has been studied in dozens of trials. A meta-analysis by Eichner and Berna in Schizophrenia Bulletin (2016) found significant effects on positive symptoms and on cognitive insight, with smaller effects on global symptom severity. A more recent meta-analysis by Penney and colleagues (JAMA Psychiatry, 2022) reviewed 43 trials and found moderate effects on positive symptoms that were maintained at follow-up. Importantly, effects appear to grow over time — possibly because participants continue to apply the skills after the group ends. The MCT website provides materials and citations.

An MCT-individualised version

An individual one-to-one variant called MCT+ has also been developed. It allows tailoring to a specific delusion or symptom and is sometimes used when group format is not appropriate.

Who tends to benefit

• People with persistent delusions or paranoia
• People who find traditional CBTp too verbal or too individualised
• People who want a group experience that doesn't feel like a "support group"
• Early-psychosis services looking for a group-based, low-cost programme to add to standard care

What MCT does not target

• Voices specifically (CBTp for voices is the better-fit approach)
• Trauma processing
• Negative or cognitive symptoms primarily
• Acute crisis management

The strengths of MCT

The free materials make it accessible. The group format is efficient. The non-stigmatising delivery — talking about cognitive biases as a universal human phenomenon, not as a defect of psychosis — often lands well. The skills learned tend to generalise: noticing jumping-to-conclusions in a non-clinical context (a misunderstanding with a colleague, a snap judgement about a stranger) builds the muscle that helps with more loaded situations later.

What participants often say

• "I never realised how quickly I was deciding things"
• "It made me curious about my own thinking instead of judging it"
• "I started asking myself, 'how confident am I really?' before reacting"

How to access MCT

1. Ask your treatment team or community mental health centre whether they offer MCT groups.
2. Clinicians can download the full materials free from the Hamburg group's website.
3. Some early intervention in psychosis services include MCT as part of their standard programme.

The bigger picture

MCT is sometimes described as the most "transferable" psychosis therapy in the world — easy to train clinicians in, free to use, and culturally adaptable. It does not promise to do everything. It promises to do one specific thing well: to teach people to notice and modify the cognitive biases that help maintain delusional thinking. Combined with medication, CBTp, and family support, it adds a useful layer to recovery — and one that many people enjoy more than they expected.
