Background: This study investigated reliability and validity of the Persian version of Impact of Event Scale-Revised (IES-R) in a sample of people from Bam after the 2003 earthquake.

Methods: The study was performed in 272 people, 4 months after Bam earthquake. For evaluating internal consistency we used α chronbach and for test-retest reliability (after 3 weeks) we used Pearson correlation coefficient. For assessing convergent validity, 50 samples completed GHQ 28(General Health Questionnaire 28) in addition to IES-R.

Results: The Persian version of IES-R has good internal consistency (α chronbach=0.67-0.87) and test-retest reliability (r=0.8-0.98 , P<0.001) and also good convergent validity. Finally, factor analysis was conducted and 3 -factor solution which explained 41.6% of the variance, was retained.

 Conclusion: In spite of good internal consistency, test-retest reliability and convergent validity regarding the result of factor analysis, there is necessity for changing some items corresponding to the Iranian culture.

Keywords: IES-R, GHQ 28, validity
