Objective: The Pediatric Quality of Life Inventory(TM) (PedsQL(TM)) Eosinophilic Esophagitis (EoE) Module is a specialized instrument designed to assess how EoE affects the quality of life in pediatric patients. This study assesses the Turkish cross-cultural adaptation of the 8-12-year-old version. Materials and Methods: As part of the cross-cultural adaptation of the Turkish PedsQL(TM) EoE Module for children aged 8-12 (Tr-PedsQL(TM) EoE), linguistic validation, content validity (CnV), construct validity (CsV), and reliability testing were conducted. Results: The study included 25 children diagnosed with EoE and their parents (n = 25). All items showed CnV indexes above 0.8. Good to excellent correlations (r = -0.459 to -0.948) between Tr-PEESS v2.0 (Frequency, Total) and Tr-PedsQL(TM) EoE Module (Total, Symptoms Total, Symptoms I-II) scores indicate CV. The 8-12-year-old version showed good to excellent internal consistency, with Cronbach's alpha values of 0.712-0.918 for children and 0.703-0.901 for parents. Conclusion: Validity and reliability analyses confirmed that the Tr-PedsQL(TM) EoE Module is a psychometrically sound instrument for use in both children and their parents.
