OBJECTIVE
The self-administered Food Allergy Quality of Life Questionnaire-Child Form (FAQLQ-CF), -Teenager Form (FAQLQ-TF) and -Adult Form (FAQLQ-AF) were recently developed within EuroPrevall, a multi-centred study of food allergy in Europe. The primary aim of this study was to evaluate the test-retest reliability of the FAQLQ-CF, -TF and -AF.
METHODS
One hundred and one Dutch patients (31 children, 34 adolescents and 36 adults) completed the FAQLQ twice with a 10-14 day interval. The intraclass correlation coefficient (ICC), Lin's concordance correlation coefficient (CCC) and Bland-Altman plots were used to assess test-retest reliability.
RESULTS
Test-retest reliability was excellent with ICCs and CCCs above 0.907, 0.975 and 0.951 for the FAQLQ-CF, -TF and -AF, respectively. Bland-Altman plots showed that the mean differences of the test and re-test were all close to zero for the FAQLQs.
CONCLUSIONS
The FAQLQs are reliable over a short time interval. The FAQLQs are not only excellent tools for group comparison studies, but also for monitoring individual patients.
目的
自我管理的食物过敏生活质量问卷儿童版（FAQLQ-CF）、青少年版（FAQLQ-TF）和成人版（FAQLQ-AF）是近期在欧洲食物过敏多中心研究EuroPrevall中开发的。本研究的主要目的是评估FAQLQ-CF、-TF和-AF的重测信度。
方法
101名荷兰患者（31名儿童、34名青少年和36名成人）间隔10 - 14天完成两次FAQLQ问卷。组内相关系数（ICC）、林氏一致性相关系数（CCC）和布兰德-奥特曼图用于评估重测信度。
结果
重测信度极佳，FAQLQ-CF、-TF和-AF的ICC和CCC分别高于0.907、0.975和0.951。布兰德-奥特曼图显示，FAQLQ问卷的测试和重测平均差异均接近零。
结论
FAQLQ在短时间间隔内是可靠的。FAQLQ不仅是群体比较研究的优秀工具，也是监测个体患者的优秀工具。
