ABSTRACT

Objective: This study aimed to examine the latest evidence for the role of metacognitive intervention in improving executive dysfunction in patients with acquired brain injury(ABI). To this end, we conducted a systematic review of Korean and international randomized controlled trials (RCTs), extracted intervention details, and analyzed the results. Methods: This study used PubMed, EMBASE, CINAHL, KCI, KISS, and RISS to search for Korean and international literature published from January 2015 to November 2022. Seven studies were selected for the final analysis according to the PRISMA checklist, and the results were presented using the PICOS method. The PEDro scale was used to evaluate the quality of the selected studies. Results: Of the 611 retrieved studies, seven were selected (n = 347), which were all “good” in quality. In assessments of executive function, activities of daily living and participation, the interventions that showed significant differences between groups after the intervention were Cognitive Orientation to daily Occupational Performance and Error-Based Learning Conclusion: This study is clinically significant as we have improved the level of evidence power for metacognitive intervention in patients with ABI by selecting only well-designed RCTs. In summary, this study provides evidence to support the use of metacognitive intervention to treat executive dysfunction in patients with ABI.
