Allergy Assessment and other Questionnaires
Parent-completed questionnaires will be administered via REDCap capturing data on atopic history, infant feeding, allergen exposure and associated risk factors for food allergy (family history of allergy, number of siblings, pet ownership, season of birth, parents’ country of birth). Participant quality of life will be measured by parent proxy using the Food Allergy Quality of Life-Parent Form (FAQL-PF) [19]. The food allergy-related quality of life questionnaire is a widely used, validated questionnaire to measure quality of life specific to food allergy. Parent reported anxiety will be measured via the State-Trait Anxiety Inventory (STAI) which is a validated questionnaire to measure parental anxiety that has been used in paediatric food allergy research previously [20, 21].
