Quality of Life in Food Allergy: Validation of Three Mini-questionnaires

The evaluation of the quality of life (QOL) in food allergy (AA) is difficult due to the lack of a currently validated questionnaire. There are only a few tools available to assess the impact of nutritional care on the QOL of the allergic patient . Available questionnaires are poorly adapted to studies dealing with large cohorts where functionality and ease of use are determining factors. The aim of this work will be to develop and validate QOL questionnaires for AA, short and easy to use, also integrating the theme of collective catering in order to assess the evolution of QOL in patients with food allergy. The target population of the questionnaires will be: i) the parents of allergic children 0 to 17 years (15 questions) ii) allergic children aged 8 to 17 years (13 questions) iii) Adults over 18 (14 questions) After receiving an information note, eligible patients or their parents will complete the questionnaires. A total of 200 patients will be recruited for each questionnaire. A statistical evaluation will be carried out using 200 questionnaires for each targeted population in order to validate the psychometric properties of the questionnaire as well as investigate the degree of correlation between the scores of the mini-questionnaire and those obtained using the Europrevall reference questionnaire.
