Abstract

Measurement is an essential activity in the field of allergy and due to the subjective nature of the results that are being measured, it is increasingly necessary to have valid, reproducible, and reliable methods. There are some reviews or task forces that present different methods or techniques to develop a validation study, which may cause some confusion. With this review, we intend to bring together and synthesize some of the information found, to help researchers and clinicians to interpret or understand the varied nomenclature read in the literature. Before any data collection, a translation of the questionnaire is needed. Psychometry involves the application of statistical techniques to test the measurement properties of an instrument. There are several measures to evaluate an instrument, the main ones being: classical test theory and modern test theory. Regarding the classical test theory, the key psychometric characteristics are scale structure, accuracy (validity), precision (reliability) and responsiveness. Modern test theory models are techniques to assess the psychometric characteristics of an instrument, focused on the dimensionality of the questionnaire. Responsiveness, validity, and precision are interlinked. Following these steps ensures the development of validated questionnaires that provide valuable insights into allergy prevalence, impact, and management.
