Validation of the Paediatric Food Allergy Quality of Life Questionnaire (PFA-QL).

Background: The Paediatric Food Allergy Quality of Life Questionnaire (PFA-QL) was the first tool to be developed for assessing health-related quality of life (QoL) in children with food allergy. It has been used in a number of published studies, but has not been validated.

Objective: The aim of the current study was to validate child (PFA-QL) and parent-proxy (PFA-QL-PF) versions of the scale in a specialist allergy clinic and in parents of children with food allergy.

The psychological impact of diagnostic food challenges to confirm the resolution of peanut or tree nut allergy.

Background: Twenty percent of children outgrow peanut allergy and 10% outgrow tree nut allergy. Resolution can be confirmed by a food challenge. Little is known about the psychosocial impact of the challenge.
