Validation of the parent-proxy reported Food Allergy-related Quality of Life Questionnaire (FAQLQ-PF-10) short form in a large, multisite longitudinal cohort of food allergic child-parent dyads

Food allergy is a common pediatric chronic condition that can impose substantial burdens on physical and psychosocial health. The parent-reported Food Allergy-related Quality of Life Questionnaire (FAQLQ-PF) is well-validated across socioeconomically, geographically and linguistically diverse populations for assessment of health-related quality of life in children with food allergy. However, its length and complexity pose substantial limitations to its broader use in both clinical and epidemiological research contexts.
