This study examined the reliability and validity of the Korean version of the anesthesia surrendering instrument (ASI), which was originally developed to measure anesthesia surrendering in Swedish adults. The study population consisted of 306 patients who received general anesthesia for abdominal, breast, knee, hip, lower back, or shoulder surgery in ten hospitals across five regions of Korea from June to September 2019. The validity of the content, construct, and criterion used, and the reliability of the ASI were assessed. The results showed that the instrument had appropriate content validity; the item-level content validity index ranged between 0.80 and 1.00, and the scale-level content validity index was 0.90. The construct validity test results confirmed four sub-categories with a total of 26 items, and the internal consistency reliability tests showed Cronbach's alpha values ranging between 0.71 and 0.88. The study findings confirmed the applicability of this instrument for measuring anesthesia surrendering in Korean adults. These results provide a foundation for future studies on anesthesia surrendering in Korean adult patients.
