    BackgroundEmergence delirium and emergence agitation have been a subject of interest since the early 1960s. This behavior has been associated with increased risk of injury in children and dissatisfaction with anesthesia care in their parents. The Pediatric Anesthesia Emergence Delirium Scale is a commonly used instrument for codifying and recording this behavior.AimsThe aim of this study was to psychometrically evaluate the Pediatric Anesthesia Emergence Delirium scale, focusing on the factor structure, in a sample of children recovering from anesthesia after surgery or diagnostic procedures. The reliability of the Pediatric Anesthesia Emergence Delirium scale was also tested.MethodsOne hundred and twenty-two children younger than seven years were observed at postoperative care units during recovery from anesthesia. Two or 3 observers independently assessed the children using the Pediatric Anesthesia Emergence Delirium scale.ResultsThe factor analysis clearly revealed a one-factor solution, which accounted for 82% of the variation in the data. Internal consistency, calculated with Cronbach's alpha, was good (0.96). The Intraclass Correlation Coefficient, which was used to assess interrater reliability for the Pediatric Anesthesia Emergence Delirium scale sum score, was 0.97 (P < .001). The weighted kappa statistics were almost perfect in 4 of 5 items, with substantial agreement in the fifth (P < .001).ConclusionThe one-factor solution and the satisfactory reliability in terms of internal consistency and stability support the use of the Pediatric Anesthesia Emergence Delirium scale for assessing emergence delirium in children recovering from anesthesia after surgery or diagnostic procedures. The kappa statistics for the Pediatric Anesthesia Emergence Delirium scale items essentially indicated good agreement between independent raters, supporting interrater reliability.© 2018 John Wiley & Sons Ltd.
