Validation and reliability of the Italian versions of the Food Allergy Quality of Life ‐Parental Burden ( FAQL ‐ PB ) and ‐Parent Form 10 ( FAQLQ ‐ PF10 ) Questionnaires

Abstract Background Food allergy (FA) may substantially impair quality of life (QoL) in affected children and their families. Reliable and culturally adapted tools are needed to assess this burden. We aimed to translate, culturally adapt, and validate the Italian versions of the Food Allergy Quality of Life Questionnaire Parent Form 10 (FAQLQ‐PF10) and the Food Allergy Quality of Life Parental Burden Questionnaire (FAQL‐PB). Methods Following World Health Organization recommendations, the questionnaires underwent forward–backward translation and psychometric validation. Internal consistency, test–retest reliability, convergent validity, and discriminant validity were assessed in caregivers of children with FA ( n  = 128) and without FA ( n  = 52). Results Both questionnaires showed high internal consistency (Cronbach's α  = 0.87 for FAQLQ‐PF10 and 0.95 for FAQL‐PB) and excellent test–retest reliability (Intraclass Correlation Coefficients 0.95 and 0.87, respectively). Moderate correlations with the Food Allergy Independent Measure (FAIM) supported convergent validity, whereas weak correlations with generic QoL and psychological distress measures confirmed disease specificity. FAQLQ‐PF10 and FAQL‐PB scores were significantly higher in the FA group than in controls (all p   Conclusions The Italian versions of the FAQLQ‐PF10 and FAQL‐PB are valid, reliable, and disease‐specific instruments for assessing FA‐related QoL. Their use may facilitate routine QoL assessment and support patient‐centered management of pediatric FA. image
