Therefore, the sample consisted of 400 students (200 females and 200 males) who were selected using random multi-stage sampling method. Measuring instruments were “Satisfaction with Life Scale”, “Oxford happiness inventory” and “Beck depression inventory”. Findings indicate that internal consistency of the scale is equal to 0.85 and Test-retest reliability is equal to 0.77. Moreover; exploratory and confirmatory factor analysis indicates that factor structure of the scales is unidimensional. What’s more, Difference between females’ and males’ scores was not significant; overall, these results suggest that Farsi version of scales is a valid and reliable measure of life satisfaction among an Iranian sample of students.
