Results: Data analysis by Kruskal- Wallis test revealed that there were significant differences between physical symptoms (χ2=5.93, P<0.05) and depression (χ 2=15.70, P<0.05), the subscales of mental health in different levels of the perceived discrimination. Furthermore, comparing personal well- being scores and its subscales in different levels of the perceived discrimination showed significant differences in personal hygiene (χ2=7.20, P<0.05), and security in future (χ2=7.60, P<0.05).

Moreover, comparing social well- being in different levels of the perceived discrimination indicated significant differences between social acceptance (χ 2=14.91, P<0.05), and social participation (χ 2= 10.91, P<0.05).
