However, in Japan, there are currently no reliable criteria or tools for diagnosing delir- ium in critically ill pediatric patients. The purpose of this study was to translate the Cornell Assessment of Pediatric Delirium (CAPD)— a screening tool for pediatric delirium—from English to Japanese for use in the diagnosis of delirium for pediatric patients in pediatric intensive care units. Methods: The back-translation method was used to ensure equivalence in the Japanese version of the CAPD and its accompanying developmental anchor points. The translation process was repeated by a multidisciplinary committee of medical researchers and clini- cians. Results: The final back-translated version of the CAPD was submitted to the original author, who gave her approval. Conclusion: The Japanese CAPD was developed and its effectiveness tested using a standardized procedure. Further study is required to test the validity and reliability of the Japanese version of the CAPD. Key words: Cornell Assessment of Pediatric Delirium, delirium, pediatric delirium Pediatric Confusion Assessment Method for the Intensive INTRODUCTION Care Unit (pCAM-ICU),6 and the Cornell Assessment of ELIRIUM IS A form of acute cerebral dysfunction and Pediatric Delirium (CAPD).7 The pCAM-ICU can be used D is associated with systemic illness or the effects of only in children over 5 years old, and the PAED scale does treatment in an intensive care unit (ICU). Delirium involves not evaluate hypoactive delirium. In contrast, the CAPD is acute and intermittent changes in mental status with disor- designed for children of all ages and can be used to assess dered attention and cognition.1 Delirium has been shown to hypoactive delirium. The CAPD is designed to give nurses a have negative clinical outcomes for in adult intensive care,2 quick and easy way to screen for pediatric patients at risk of such as increased length of hospital stay,3 mortality, and delirium.8 It consists of eight question items that correlate health-care costs.4 However, the implications of pediatric with the diagnostic domains of awareness and cognition. delirium in the Japanese context are not well clarified The nurse administering the CAPD answers each item on a because of the lack of an adequate screening tool. Currently, 5-point Likert scale, the total score of which gives an indica- there are a number of validated and reliable screening tools tion of risk for delirium.
