Background: The present study aimed to examine the psychometric properties of the Persian version of the 23-item PedsQL™ 4.0 Generic Core Scales in Iranian children with attention deficit hyperactivity disorder (ADHD).
Methods: A clinical sample of seventy-two children aged 8-17 years with ADHD and their parents completed the questionnaire. The control group consisted of 140 children matched for age and gender selected from schools by cluster sampling method. The English language version of the PedsQL™ 4.0 was translated into Persian. Factor analysis was conducted.
Results: Reliability analysis for the total scale score was 0.85 for the child report and it was 0.80 for parent report version. Factor loading for items of the questionnaire was very similar to its original version. The quality of life of children with ADHD was statistically lower than that of the control group.
Conclusion: The Persian version of the scales has adequate reliability and validity. The HRQOL of children with ADHD is lower than that of the control group. It is lower than that of the community sample of ADHD children from USA or children with cancer.
