This study focused on the relationship between regulatory focus and creative performance. We investigated the effects of ego involvement on enhancing motivation in task performance. We hypothesized that there are no differences in creativity based on the degree of ego involvement in promotion-focused individuals, whereas creativity would be higher in prevention-focused individuals with higher ego involvement. University students (N = 128) participated in the study. The results supported the hypothesis. When ego involvement was high, there were no differences in creativity between promotion-focused and prevention-focused individuals on three indicators of creativity. Based on these three indicators, prevention-focused individuals were more creative than promotion-focused individuals. Moreover, prevention-focused individuals who worked on a task patiently and persistently achieved equal or better creative performance than promotion-focused individuals.
