Abstract
Purpose: This study aimed to translate and cross-culturally adapt the QUAlity of Life Assessment in Spina bifida for Children (QUALAS-C) and validate the Korean version of the QUALAS-C (QUALAS-C-K).
Materials and Methods: Three urologists translated the QUALAS-C into Korean. Facial and content validity were assessed in the pilot study. Back-translation into English was performed. In the main study, the QUALAS-C-K and Korean version of KIDSCREEN-27 were administered simultaneously. Test-retest reliability was confirmed by re-administering the QUALAS-C-K. Internal consistency was verified using Cronbach's alpha. Factor analysis was performed, and convergent and divergent validity were demonstrated using the Korean version of KIDSCREEN-27.
Results: A total of 53 children with spina bifida participated in the main study. Cronbach's alpha for the overall instrument determined good internal consistency (0.72-0.85), the intraclass correlation coefficient showed good stability (0.74-0.77), and the factor analysis converged to the same two-factor structure as in the original version. Construct validity revealed weak-to-moderate associations ( r ≤ 0.57) between QUALAS-C-K and K-KIDSCREEN-27, indicating that QUALAS-C-K measures different aspects of the HRQOL than K-KIDSCEEN-27.
Conclusions: The QUALAS-C-K is a reliable and valid instrument for assessing the health-related quality of life of children with SB in Korea.
