We aimed to assess the validity and reliability of the Korean versions of the Food Allergy Quality of Life Questionnaire?Child Form (K-FAQLQ-CF) and the Food Allergy Quality of Life Questionnaire?Teenager Form (K-FAQLQ-TF). Patients aged 8?17 years with food allergy (FA) were enrolled and completed the Korean versions of the questionnaires, including the K-FAQLQ-CF, the Food Allergy Independent Measure?Child Form (K-FAIM-CF), and the Pediatric Quality of Life Inventory™ (K-PedsQL™ 4.0) for children and the K-FAQLQ-TF, the Food Allergy Independent Measure?Teenager Form (K-FAIM-TF), and the K-PedsQL™ 4.0 for adolescents. We enrolled 56 children and 23 adolescents in this study. The K-FAQLQ-CF showed a good internal consistency (Cronbach’s α coefficient = 0.969) and an excellent test-retest reliability (intraclass correlation coefficient = 0.914, P = 0.011). There was a moderate correlation between the K-FAQLQ-CF and K-FAIM-CF scores (β = 0.736, P < 0.001), indicating construct validity. The K-FAQLQ-CF score was weakly associated with the K-PedsQL™ 4.0 score (β = ?0.289, P = 0.031), verifying convergent and discriminant validities. The K-FAQLQ-TF also showed a good internal consistency (Cronbach’s α coefficient = 0.966) and test?retest reliability (intraclass correlation coefficient = 0.974, P = 0.005). Construct validity was also established by a moderate correlation with the K-FAIM-TF (β = 0.699, P < 0.001). Our results suggest that the K-FAQLQ-CF and K-FAQLQ-TF are valid and reliable tools to evaluate the quality of life of children and adolescents with FA in Korea.
