Food allergy quality of life questionnaire (FAQLQ)
HRQL assessments were conducted at screening (T0), T2, T4 and T5. The validated Food Allergy Quality of Life Questionnaire-Parent Form (FAQLQ-PF) was completed by parent/caregiver on behalf of the patient13. FAQLQ-PF total score (global impact) and subscales (general emotional impact, food anxiety, social and dietary limitations) were calculated. Lower scores indicate better HRQL (i.e. lower food allergy burden). The minimal clinically important difference (MCID) for FAQLQ-PF is 0.45 points13. The food allergy independent measure (FAIM) was used to assess the parent’s perception of the chance of an adverse outcome for their child with food allergy14.
