Purpose: To investigate the cultural adaption, validity, and reliability of the Functional Disability Inventory (FDI) in Turkish children and adolescents with chronic headache. Materials and methods: The original version of the FDI was translated to Turkish, back-translated and synthesized. The validity of the Turkish version of the FDI was examined using confirmatory factor analysis, discriminant validity and similar scale validation. Internal consistency and test-retest analyses were performed to determine the FDI reliability on 210 children and adolescents with chronic pain and 101 typically developing children and adolescents, all aged 8 to 18 years. Results: The Turkish version of the FDI was found to have excellent internal consistency (Cronbach's's α = 0.91) and test-retest reliability (ICC = 0.97). The confirmatory factor analysis identified a two-factor structure of the FDI. Scores on the FDI correlated with similar scales. There were significant differences in average total and average item scores of FDI between the two groups. Conclusion: The results of the current study demonstrated that the FDI has appropriate psychometric qualities and is valid and reliable for application among children and adolescents with chronic pain. Clinical Trial Number: NCT05422456.
