The purpose of this study was to examine the validity and reliability of the USSI among Fars province university students by using exploratory and confirmatory factor analysis. The results showed that the two factors (Inter & Intra Personal Stress and Academic stress) were significant related to the USSI general factor. The Goodness-of-Fit Index, the Adjusted Goodness-of-Fit Index, and the Root Mean Square Error of Approximation were significant. These indices supported theoretically that the construct of University Students Stress Inventory is psychometrically sound and fit the model. Concurrent validity showed that the scores of mental health and its factors such as bodily symptoms, anxiety, disorder in social function and depression are significantly relate to Inter & Intra Personal Stress and Academic stress factors. The Cronbach coefficient alpha values and test-retest correlations were satisfactory for total scores' USSI and its subscales. The results showed that the USSI is a reliable and valid measure of assessing stress level among Iranian university students.
