Abstract:
PURPOSE: The modified Yale Preoperative Anxiety Scale (mYPAS) was developed for evaluating the level of preoperative anxiety in children. The purpose of this study was to develop a Korean version of the mYPAS (K-mYPAS) and to establish its validity and reliability based on the Korean preoperative pediatric patients. METHODS: K-mYPAS was made through stringent back-translation procedure. Total enrolled 102 patients answered questionnaires of Korean version of State-Trait Anxiety Inventory for Children (K-STAIC), and were videotaped for 2 to 5 minutes before induction of anesthesia. Three observers of experienced psychiatrist, surgeon, and nurse analyzed videotape with K-mYPAS comparing to K-STAIC. The inter- and intraobservers reliability, concurrent and construct validity, sensitivity, specificity, and predictive value were analyzed. RESULTS: The value of Cronbach alpha for interobservers reliability was 0.939 and intraobserver reliability was statistically significant (P < 0.001). Concurrent and construct validity were also statistically significant (P < 0.001 and P < 0.001, respectively). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 81.3%, 91.4%, 81.3%, 91.4%, and 88.2%, respectively. CONCLUSION: The K-mYPAS had good psychometric properties and can be used as a reliable and valid instrument for the assessment of preoperative anxiety in children.
