“…One of the four studies also evaluated test-retest reliability of the FAQLQ-CF. The intraclass coefficient (ICC) was found to be excellent (ICC = 0.91) (10) and the same study identified the concordance correlation coefficient (CCC) as 0.907, as well as a Bland-Altman plot demonstrating that the mean differences of the test and retest were close to zero for the FAQLQ-CF (10).…”

“…This is particularly relevant in the context of food allergy, where unless individuals are exposed to the specific food, they may have no symptoms or problems other than the anxiety resulting from the need for continued avoidance (9). The disease-specific questionnaires that have been developed are significantly more sensitive in measuring the response to interventions or future treatments as well as estimating the general burden of food allergy (10).…”

This is one of seven interlinked systematic reviews undertaken on behalf of the European Academy of Allergy and Clinical Immunology as part of their Guidelines for Food Allergy and Anaphylaxis, which focuses on instruments developed for IgE-mediated food allergy. Disease-specific questionnaires are significantly more sensitive than generic ones in measuring the response to interventions or future treatments, as well as estimating the general burden of food allergy. The aim of this systematic review was therefore to identify which disease-specific, validated instruments can be employed to enable assessment of the impact of, and investigations and interventions for, IgE-mediated food allergy on health-related quality of life (HRQL). Using a sensitive search strategy, we searched seven electronic bibliographic databases to identify disease-specific quality of life (QOL) tools relating to IgE-mediated food allergy. From the 17 eligible studies, we identified seven disease-specific HRQL instruments, which were then subjected to detailed quality appraisal. This revealed that these instruments have undergone formal development and validation processes, and have robust psychometric properties, and therefore provide a robust means of establishing the impact of food allergy on QOL. Suitable instruments are now available for use in children, adolescents, parents/caregivers, and adults. Further work must continue to develop a clinical minimal important difference for food allergy and for making these instruments available in a wider range of European languages.The term 'food allergy' refers to the subgroup of foodtriggered reactions in which immunologic mechanisms have been implicated, whether immunoglobulin E (IgE)-mediated, non-IgE-mediated, or involving a combination of IgE-and non-IgE-mediated etiologies (1). This review focuses on food allergy that is likely to have an IgE-mediated etiology.Allergy 69 (2014) 834-844

Attitudes Towards Food Allergy Scale: Psychometric properties and associations with food allergy quality of life and anxiety

Background Daily, we tend to evaluate things positively or negatively, according to whether they follow the general information available about them. This attitudinal assessment is represented through evaluative dimensions (e.g., good‐bad) that vary in terms of valence (positive or negative) and strength (less or more). Despite its importance, there is an urge in food allergy (FA) research to properly assess attitudes based on the underlying mechanisms that define attitudes. Objective The present research aimed to develop the Attitudes Towards Food Allergy scale (ATFAS), the first attitudinal measure of FA. Method: Two studies were performed (n = 1049), using a range of robust statistical analyses (e.g., Item Response Theory, Exploratory Factor Analysis, Confirmatory Factor Analysis). Results Our results provided strong evidence for a unidimensional attitudinal structure, across groups of non‐allergic individuals and food‐allergic, besides recommended reliability levels. All items presented suitable parameters (i.e., discrimination, difficulty, information). Finally, the ATFAS significantly predicted FA quality of life, mediated by FA anxiety. Conclusion We are confident that the ATFAS is a novel and necessary measure, that can help to widen how we view and assess FA. The development of studies that assess attitudes towards FA based on our general information about the disorder would help to deepen our understanding of their links to other health‐related variables and their potential impact on quality of life, reduce FA's stigma, and develop more positive attitudes.
