Development and Validation of the Japanese Version of the Scale of Perfectionism and Excellencism (SCOPE)

This study aims to develop a Japanese version of the Scale of Perfectionism and Excellencism (SCOPE), which captures personalities pursuing high standards. Three hundred and sixty students reported their scores on the SCOPE, a pre-existing perfectionism scale, achievement motivation, life satisfaction, emotional states, and anthropophobic tendencies. Confirmatory factor analysis identified two factors: perfectionism and excellencism. Regression analyses demonstrated that perfectionism was associated with the pre-existing scale of perfectionism, fear of failure, and anthropophobic tendencies, whereas excellencism was associated with achievement motivation and liveliness. These findings highlight the maladaptive nature of perfectionism and support the validity of the Japanese version of the scale.
