 Purpose of this study is to examine reliability and validity of the Japanese version of NEECHAM Confusion Scale (J-NCS). J-NCS is an assessment scale of acute confusion state, and it was translated by Watanuki et al. (2001). Subjects were 32 surgical patients. Present results demonstrated good internal consistency with a coefficient of Cronbach's alpha, 0.83. And inter-rater reliability was also good, and differences between two ratings were less than 1-2 points. Therefore its reliability was satisfactory. Regarding validity, construct validity showed significant association with ADL and the severity of illness, and indicated low correlation with age, sex, environment, etc. Regarding concurrent validity, high validity (r=.76, p<.01) was displayed with relation to the positive item of delirium of DSM-IV. Above findings are consistent with that of the original NCS, and suggested that J-NCS have sufficient reliability and validity for practical use.
