The goal of this study was to describe the mediating role of self-concept in perfectionism and mental health. The sample group in this study included 400 high school students (200 boys and 200 girls) from Shiraz with the mean age of 16. 37±0. 93 for the girls and 16. 12±0. 63 for the boys. Data were gathered through the application of three scales: Mandaglio and Pyerist Self-concept Scale (P. M. S. P. S); Depression and Anxiety and Stress Scale of Lovibond and Lovibond (DASS-21); and Negative and Positive Perfectionism Scale of Terri-Short et. al. The validity and reliability of these scales were reviewed during this study. The result of the Path analysis test showed the mediating role of self-concept in perfectionism and mental health. This analysis illustrated that negative and positive perfectionism، both in a direct and indirect way، had a significant role in mental health. The rate of the direct effect of positive perfectionism on mental health was 0. 17 (p value <0. 001) and the rate of the indirect variable through self-concept was 0. 06 (p value <0. 001). Also، the rate of the direct effect of negative perfectionism on mental health was 0. 39 (p value <0. 001) and rate of the indirect effect of this variable on self-concept was 0. 01 (p value <0. 001). the findings of this study showed that self-concept had a mediating role in mental health and perfectionism. In other words، positive perfectionism of a person has a positive effect on self-concept and، as a result، positive self-concept confers mental health improvement. On the other hand، negative perfectionism leading to a decrease in mental health and an increase in excitement problems of a person.
