Abstract
Aim : It was aimed to evaluate reliability and validity of Japanese version RAS (J-RAS) among the executive nurses. Method : Attributes of the objects, the ways of their stress-copings and the feature of their assertiveness by J-RAS was investigated. The investigation targeted 203 objects consisted of head nurses, sub-head nurses or chief nurses working for three university hospitals in Tohoku Kanto area. Results : The Japanese version of the RAS indicated high coefficients of reliabilities in a test re-test (r=0.71 p<0.01), split-half reliability test (r=0.79 p<0.01), Cronbach's alpha (0.82 p<0.01). Six factors were extracted by using factor analysis in principal factoring with a Parsimax rotation, so the Japanese scale had a few implicative differences from the original RAS, but its validity was suggested to be high. High validity was also evaluated by acknowledging average point of stress-coping method. Consideration : It was evaluated that J-RAS had high internal consistency and high validity. Moreover, executive nurses' assertiveness score was higher than novice nurses'. Head nurses tended to have higher assertiveness score than sub-head nurses. As a result of this research, reliability and validity of J-RAS for the executive nurses were suggested.
