Objective: The purpose of this study was to systematically review the study of metacognitive intervention forpatients with schizophrenia to analyze and present intervention effects, assessment tools, and protocols.
Methods: Previous studies published from 2015 to 2020 were searched from the ebscoHOST, Embase, psycINFO,and Pubmed databases. The key terms included ‘Schizophrenia’ OR ‘Schizo’ OR ‘Phychosis’ AND ‘Metacognitive’OR ‘Metacognition.’ Finally, 15 randomized control trials (RCTs) were selected based on the selection criteria.
Results: Most of the participants were patients with chronic schizophrenia who had participated in an outpatientprogram. The effects of metacognitive intervention showed positive results in three areas, i.e., psychiatricsymptoms, psychosocial factors, and cognitive functions. A total of 44 assessment tools were used, with thePositive and Negative Syndrome Scale (PANSS) accounting for the largest proportion. Metacognitive training(MCT) showed the highest frequency, and in general, the intervention was held once or twice a week, for 40 to60 min, and the total number of sessions in the form of group programs was less than 20.
Conclusion: The results of this study revealed that metacognitive intervention is effective for various symptoms ofschizophrenia and is meaningful in that it provides evidence for clinical practice.
