This methodological study translated PEESv2.0 into Turkish through standardized forward-backward translation and cultural adaptation steps.
This methodological study translated PEESv2.0 into Turkish through standardized forward-backward translation and cultural adaptation steps. Of these, 58 (39.1%) completed the parent-by-proxy version and 70 (54.7%) completed the patient version. Cronbach's alpha and intraclass correlation coefficient for test-retest reliability exceeded 0.70 for all domain and total scores in both questionnaires. Discriminant validity was demonstrated by significant differences in subscale and total scores between the EoE patient group and age-matched healthy controls (P < 0.05). A limitation acknowledged by the authors was the absence of construct validity testing against another existing symptom measure. The study concluded T-PEESv2.0 is valid and reliable for clinical and research use in Turkish pediatric EoE patients aged 2 to 18 years.
