To measure the relationship between psycho-social health and national-religious identity among Yazdi high school students a sample of 354 students was selected using a cluster sampling method. Measures used to assess the constructs are of acceptable validity and high internal consistency (alpha= 0.75). Statistical analyses revealed a significant correlation between the two constructs, yet the national-religious identity has no relationship with SES. Furthermore, a significant difference was observed between male and female students in terms of religious identity. Also, %19 of the variance in identity is explained by the psycho-social health. Further research in this area is recommended.
