The purpose of this study was to investigate the mediating effect of achievement motivation in the
relation between perfectionism and conflict, and to present a multigroup analysis of employment status.
To conduct the study, 651 questionnaires were collected from the staff in large and medium-sized
companies. The results of this study are summarized below. First, self-oriented perfectionism negatively
affects conflict, but socially-prescribed perfectionism has a positive impact on it. Second, self-oriented
perfectionism significantly affects achievement motivation, but socially-prescribed perfectionism has no
significant impact on it. Third, achievement motivation has a significant mediating effect between
perfection and conflict. Fourth, the moderating effect was not evident from multigroup analysis of
employment status. However, contingent employees lacked motivation, but were more prone to conflict.
The contribution of this study is severalfold. The results of this study can be utilized as factors to
mitigate conflict. It offers ideas on how to improve self-oriented perfectionism and achievement
motivation, and minimize the pressure by socially-prescribed perfectionism through corporate education.
Finally, dedicated encouragement programs for contingent employees to perform more efficiently and
supporting their personal wellbeing through corporate education were highly recommended.
