Cross-cultural adaptation and validation of the Korean version of the facial disability index in patients with facial palsy.

ABSTRACT: ObjectiveTo translate and culturally adapt the facial disability index (FDI) into Korean following established guidelines, and to evaluate its reliability and validity in patients with facial palsy.MethodsThe translation process followed Beaton's cross-cultural adaptation methodology, involving forward translation, back translation, expert committee review, and prefinal testing. This prospective cross-sectional observational validation study included 100 adult patients with facial palsy recruited from a facial palsy center between May and July 2021. Reliability was assessed using Cronbach's α for internal consistency and intraclass correlation coefficient (ICC) for test-retest reliability (3-week interval). Construct validity was examined using Spearman's correlation between the Korean FDI
