Abstract
This study developed a Japanese version of the Ego-Resiliency Scale (ER89; Block & Kremen, 1996), and examined its reliability and validity. In Study 1, a Japanese version of the ER89 was developed using questionnaire data from 540 undergraduates. Principal component analysis revealed that one of the 14 component structure items corresponded to the original version; this scale had a sufficiently high degree of internal consistency (α=.82). In Study 2, the validity of the scale was tested. The questionnaire was completed by 261 undergraduates (Sample 1) and 240 undergraduates (Sample 2). The scale's concurrent and construct validities were confirmed on the basis of the relationship with other concepts—resiliency and mental health. The Japanese version of the ER89 was shown to have high reliability and validity.
