BACKGROUND Metacognitive training (MCT) was developed in 2007 and widely used to modify the delusions for patient with schizophrenia. However, its effectiveness remains unclear. AIMS To investigate the overall effectiveness of MCT for delusion in schizophrenia patients from 2007 to 2016, and to investigate the variables (intervention approach, intervention dose, and participant factors) of an MCT study that could influence the effect size. METHODS Parallel-arm design of MCT for delusions… 
A randomised controlled trial of metacognitive training for psychosis, depression, and belief flexibility.
TLDR
Large and stable symptom reductions in delusions and depression, and smaller (yet stable) improvement in belief flexibility across groups, following a 4-session MCT are demonstrated, carrying implications for transdiagnostic process-based interventions and their mechanisms of change.
Effects of Metacognitive Training on Cognitive Insight in a Sample of Patients with Schizophrenia
TLDR
The findings showed that the implementation of the MCT program in real clinical settings can contribute to an improvement in the metacognitive ability and symptomatology of people with schizophrenia.
Individualized Metacognitive Training (MCT+) Reduces Delusional Symptoms in Psychosis: A Randomized Clinical Trial
TLDR
This study adds further efficacy to the MCT program, and suggests that even brief psychotherapy can help to ameliorate the symptoms of psychosis.
The efficacy of extended metacognitive training for psychosis: A randomized controlled trial
TLDR
Support is provided for the efficacy of 10 module MCT concerning positive symptomatology (especially, delusion) and general functioning and there was a trend for greater efficacy of MCT on cognitive biases.
Moderators of treatment efficacy in individualized metacognitive training for psychosis (MCT+).
TLDR
Patients with low self-esteem and those who are prone to jumping-to-conclusions seem to particularly benefit from MCT+, and these results can help inform clinical practice as they provide specific criteria for selecting patients for whom MCT+ is most appropriate.
Effectiveness of metacognitive interventions for mental disorders in adults-A systematic review and meta-analysis (METACOG).
TLDR
Metacognitive interventions are likely to be effective in alleviating symptom severity in mental disorders and their add-on value against existing psychological interventions awaits to be established, potential advantages are their low threshold and economy.
Can metacognitive interventions improve insight in schizophrenia spectrum disorders? A systematic review and meta-analysis
TLDR
Metacognitive interventions, particularly Metacognitive Training, appear to improve insight in patients with SSD, especially cognitive insight shortly after treatment, although long-term RCTs are needed to establish whether these metac cognitive interventions-related insight changes are sustained over a longer time period and result in better outcomes.
Assessing the efficacy and feasibility of providing metacognitive training for patients with schizophrenia by mental health nurses: A randomized controlled trial.
TLDR
The metacognitive training administered by psychiatric and mental health nurses was effective in ameliorating delusions and social functioning over time and it immediately reduced hallucinations post-treatment.
Effects of a Korean version of the metacognitive training program for outpatients with schizophrenia on theory of mind, positive symptoms, and interpersonal relationships.
TLDR
The results suggest that the MCT program can be a complementary psychotherapy that contributes to symptom relief and interpersonal functioning in patients with schizophrenia, and is effective in the Korean culture, beyond the Western context.
A randomized controlled trial to evaluate the efficacy of metacognitive training for people with schizophrenia applied by mental health nurses: Study protocol.
TLDR
AIM to evaluate the efficacy of the Portuguese version of the metacognitive training programme for schizophrenia and its effects on psychotic symptoms, insight into the disorder and functionality and it is expected that at the end of the programme, the experimental group will have reduced severity of psychotic symptoms and improved insight Into the disease and functionality.

Acceptance and Efficacy of Metacognitive Training (MCT) on Positive Symptoms and Delusions in Patients With Schizophrenia: A Meta-analysis Taking Into Account Important Moderators.
TLDR
This meta-analysis demonstrates that MCT exerts a small to moderate effect on delusions and positive symptoms and a large effect on acceptance of the intervention.
Metacognitive training for schizophrenia: a systematic review
TLDR
More randomized trials that use standardized outcome measures, that use intention-to-treat analyses, and that follow-up participants at regular intervals after the intervention are needed to determine whether or not MCT should become a recommended adjunctive treatment for schizophrenia.

TLDR
The results support the use of process-based interventions that target psychological mechanisms underlying specific psychotic symptoms as adjuncts to more conventional approaches.

Complementary group Metacognitive Training (MCT) reduces delusional ideation in schizophrenia
TLDR
MCT, a low-intensity training aimed at enhancing patients' awareness of cognitive biases subserving paranoia, led to improvement in delusion symptoms relative to the control condition and over and above the effects of antipsychotic medication.
Further evidence for the efficacy of a metacognitive group training in schizophrenia.
TLDR
The present study confirms prior reports that MCT exerts beneficial effects on some cognitive and symptomatic parameters and reduces the rate of jumping to conclusions bias after training.
Sustained antipsychotic effect of metacognitive training in psychosis: A randomized-controlled study
TLDR
The results of this study indicate that MCT training has a surplus antipsychotic effect for patients suffering from schizophrenia-related disorders who demonstrate only a partial response to antipsychotics treatment and that the effect of the intervention persists for at least 6 months after the intervention.
Antipsychotic treatment beyond antipsychotics: metacognitive intervention for schizophrenia patients improves delusional symptoms
TLDR
The results suggest that the combination of a cognition-oriented and a symptom-oriented approach ameliorate psychotic symptoms and cognitive biases and represents a promising complementary treatment for schizophrenia.
Metacognitive group training for schizophrenia spectrum patients with delusions: a randomized controlled trial
TLDR
In the present study, MCT did not affect delusion scores and self-reported cognitive insight, or subjective experience of cognitive biases and metacognitive beliefs, and MCT was not cost-effective.
