The data were analyzed using descriptive statistics including mean, standard deviation ..., and inferential statistics including Pearson correlation coefficient and path analysis. According to the results of statistical analyzes and information obtained from subjects, the hypotheses suggest that self-esteem and perfectionism can predict depression. Depression is also predictable with respect to self-esteem and the role of gender mediation. Meanwhile, depression is predictable due to perfectionism and gender mediation .But because of the interactive effect that variables put on each other, our overall research hypothesis is rejected.

While perfectionism and self-esteem can predict the amount of depression with or without gender mediation.
