The purpose of this study was to examine the reliability and the validity of the BARRIERS Scale Japanese version. BARRIERS Scale consists of 28 items in 4 subscales. This scale used 5- point Likert type response scale including no opinion. The study subjects were 527 nurses, who work in general hospital at Fukuoka prefecture, and took part in the courses of management and nursing research. This study carried out through on 9 April in 2002 from on 19 June in 2001.
Internal consistency, Cronbach's α coefficient were 0.76 to 0.83. This result supported the reliability of BARRIERS Scale Japanese version.
With regard to content validity, two educators in nursing college found validity of 28 items with subcategories. The construct validity was examined using exploratory factor analysis and confirmatory factor analysis. Five factors, consisting of 28 items, were extracted by exploratory factor analysis (cumulative contribution rate was 36.048%). The chi-square test for goodness of fit showed higher fitness (Χ
2=188.068, df=248, p=0.998). The five factors model indicated an acceptable fit to the data by confirmatory factor analysis (GFI=0.902, AGFI=0.885, RMSEA=0.046, AIC=842.862, CAIC=1164.161). As compared with structure of factors between this study result and Funk's result, the factors of Innovation, Organization and Adopter were closely, in addition to the factors of Communication was broken up.
From the mentioned above, BARRIERS Scale Japanese version have sufficiently the reliability and the validity.
