Validity and Reliability of the Korean Anesthesia Surrendering Instrument
Abstract Background : In Korea, to reduce patients’ anxiety regarding anesthesia induction and to increase compliance, the nurses need a measurement for understanding of anesthesia surrendering. 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. Methods: 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. We assessed the validity of the content, construct, and criterion used, as well as the reliability of the ASI. Results: The results showed that the instrument had appropriate content validity with the item-level content validity index ranging between 0.80 and 1.00 and a scale-level content validity index of 0.90. The construct validity test results showed that it comprised 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. In summary, the results confirmed that the Korean ASI had adequate reliability and validity. Conclusion: The study findings confirmed the applicability of this instrument for measuring anesthesia surrendering in Korean adults. Moreover, these results may be used in future studies on anesthesia surrendering in Korean adult patients.
