Attempts to apply cognitive‒behavioral therapy（CBT）to treat patients in the early stage of psychosis, including those with First‒Episode Psychosis（FEP）and those with an At‒Risk Mental State（ARMS）, have recently attracted considerable attention. Such CBT for FEP focuses on promoting the recovery process and relapse prevention, although evidence on its efficacy is currently limited. Further, studies on CBT for ARMS have not consistently demonstrated its effectiveness. Some reports affirm the effectiveness of CBT in FEP prevention, while others claim that the treatment leads to no compelling difference in comparison to nonspecific treatment such as supportive therapy and treatment as usual. It is evident that psychosocial interventions play a fundamental role in the treatment of early stages of psychosis. Therapeutic approaches based on CBT have been applied to various cases；however, further research is necessary in order to produce more concrete results and obtain the evidence needed to approve this method.
