This study developed a scale for evaluating the self-expression styles of university students and then verified its reliability and validity. Participants were 186 university students who were asked to complete a questionnaire containing questions about self-expression, shyness, aggressiveness, and assertion. The factor analysis revealed a scale consisting of four factors: assertive, aggressive, submissive, and indirect. Internal consistency was found to be sufficient, and partial validity was confirmed. These results indicate that the scale is useful for measuring the tendencies of an individual’s self-expression.
