Abstract

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.

METHODS:

For the clinic sample, a generic QoL scale (PedsQL) and the PFA-QL were completed by 103 children (age 6-16 yrs) with peanut or tree nut allergy; test-retest reliability of the PFA-QL was tested in 50 stable patients. For the non-clinical sample, 756 parents of food allergic children completed the PFA-QL-PF, the Child Health Questionnaire (CHQ-PF50), Food Allergy Quality of Life Parental Burden Scale (FAQL-PB) and a Food Allergy Impact Measure.

RESULTS:

The PFA-QL and PFA-QL-PF had good internal consistency (α's of 0.77-0.82), and there was moderate-to-good agreement between the generic- and disease-specific questionnaires. The PFA-QL was stable over time in the clinic sample, and in both samples, girls were reported to have poorer QoL than boys.

CONCLUSIONS:

The PFA-QL and PFA-QL-PF are reliable and valid scales for use in both clinical and non-clinical populations. Unlike other available tools, they were developed and validated in the UK and thus provide a culture-specific choice for research, clinical trials and clinical practice in the UK. Validation in other countries is now needed.
