Abstract

The study aimed to translate and adapt the traditional Chinese Food Allergy Quality of Life-Parental Burden Questionnaire (TC-FAQL-PB) into simplified Chinese language and determine the validity and reliability of the translated version. A methodologic study design involving instrument translation and psychometric evaluation was used for the present study. The simplified Chinese FAQL-PB (SC-FAQL-PB) was developed following Guillemin's guidelines for cross-cultural adaptation. A convenience sample of 230 participants was recruited. The psychometric properties were examined using internal consistency, test-retest reliability, item discrimination, content validity and construct validity. The values of I-CVI ranged from 0.83 to 1.00. The CFA model revealed that the study supported the two-factor model. The questionnaire had good internal consistency with a Cronbach's alpha coefficient of 0.946. The item-total correlation values ranged from 0.707 to 0.866. Test-retest reliability showed that the intraclass correlation coefficient was 0.926 (95% CI, 0.830-0.968).
