Abstract
Present research reviews previous studies on metacognitive beliefs and the role of metacognitive therapies in the treatment of the patients suffering from Schizophrenia which is one of the most important psychological disorders. Patients suffering from schizophrenia have shown a serious change in perception, emotion, cognition, thinking, and also behavior. Harmful metacognitive beliefs, cognitive biases, inability to perceive other people’s points of view, repetitive and dysfunctional thinking processes, etc. are just a few drawbacks of Schizophrenia.
Additionally, some studies have shown more specific metacognitive beliefs in schizophrenic patients, however, there were differences between the results of various studies.
This research highlights the results of some previous studies on metacognitive beliefs and the effect of metacognitive therapies in the treatment of patients being subjected to schizophrenia disorders. This may be a sparkle of hope in diagnosing psychological conditions affecting schizophrenia, and also paves the way to effective psychological therapies for schizophrenic patients. It should be emphasized that the diversity of the results from previous researches in this field was probably due to the chronic, under-treated, acute status of the patients, the number of patients, culture role, the degree of the resilience, and so on.

Key words: Schizophrenia, Metacognitive beliefs, Metacognitive therapies.
