Development and validation of the self-administered Food Allergy Quality of Life Questionnaire for adolescents

The FAQLQ-TF is the first self-administered, disease-specific HRQL questionnaire for adolescents with food allergy. It has good construct validity and excellent internal consistency and discriminates between adolescents who differ in the number of food allergies. The FAQLQ-TF is short and easy to use and might therefore be a useful tool in clinical research.
