Reliability and validity of the Persian version of Global School-based Student Health Survey adapted for Iranian school students

• Purpose: Global School-based Student Health Survey (GSHS) is a project supported by the World Health Organization to assess adolescent health-risk behaviours and protective factors. The present study reports test-retest and internal consistency reliability as well as Content Validity Index (CVI) for the Persian version of GSHS and Global Youth Tobacco Survey (GYTS) adapted for Iranian students.Methods: The original English GSHS, GYTS and Optional Shisha modules were translated and back-translated, pilot-tested, reformed and corrected for clarity. The back-translated and English versions were compared and the Persian version was then edited to reach consistency for two versions. In order to evaluate the performance of this measure for our study sample (n= 47), we examined its test-retest reliability, internal consistency, and correlation between total test and re-test scales score as well as CVI.Results: The internal consistency (Cronbach's alpha) for the whole GSHS Core modules was 0.69, and for Core-Expanded GSHS, GYTS and Optional Modules for Shisha was 0.90. Test-retest reliability varied between 0.51 and 1.00 for Core and 0.23 to 1.00 for Core-Expanded GYTS and Optional Modules of Shisha. Total test and re-test scales score for GSHS Core varied from 0.64 to 1.00, and for Core-Expanded GSHS, GYTS and Optional Modules of Shisha varied 0.67 to 0.91.Conclusion: The Persian version of GSHS Core, Core-Expanded and GYTS has acceptable reliability and validity, and can serve as a reliable instrument for Persian-speaking communities.
