Objective: to present and discuss conceptual bases and methods for evaluating the content, construct and criterion validity of self-reported measuring instruments. Method: theoretical study based on the concepts of the Consensus-based Standards for the Selection of Health Measurement Instruments and those evaluated in the Evaluating the Measurement of Patient-Reported Outcomes, which includes concepts of instrument assessment to assess patient-reported outcomes. Results: validity is significant for the methodological quality of an instrument; however, it is a relative criterion, since it depends on the adequacy of the instrument to be measured. There are three different validity measurement properties described in the literature: content, construct and criterion validity. Conclusions: as validity is an important property, it is recommended that it be verified in studies that aimed to develop new scales and in those that adapted and validated for another culture or population.
Objective: to present and discuss conceptual bases and evaluation methods that support important properties of measurement instruments.Method: a theoretical study based on the international and national literature and the Consensus-based Standards for the selection of health Measurement Instruments e Evaluating the Measurement of Patient-Reported Outcomewhich contemplates concepts of evaluation of instruments for the evaluation of results reported by the patient. Initially, the concepts of reliability, responsiveness and interpretability are mentioned and discussed, as well as the main ways of evaluating the properties Results: it can be seen that there are still differences in some conceptual descriptions. However, the authors emphasize the importance of reliability in order to evaluate the measuring instrument. It is important to note the importance of knowing and understanding the Conceptual Model, the properties of measurements and the different evaluation methods that guarantee reliable and valid results, especially in the instrument validity studies.Conclusions: the discussion presented on reliability, responsiveness and interpretability which contributes to health professionals with theoretical knowledge, and a critical sense in the choice of instruments and in conducting analyzes on these measurement properties.DESCRIPTORS: Data accuracy. Psychometry. Validation studies. Surveys and questionnaires. Precision of dimensional measurement. PROPRIEDADES PSICOMÉTRICAS DE INSTRUMENTOS DE MEDIDAS: BASES CONCEITUAIS E MÉTODOS DE AVALIAÇÃO -PARTE I RESUMOObjetivo: apresentar e discutir bases conceituais e métodos de avaliações que fundamentam importantes propriedades de instrumentos de medidas. Método: estudo teórico embasado na literatura internacional e nacional e nos instrumentos Consensus-based Standards for the selection of health Measurement Instruments e Evaluating the Measurement of Patient-ReportedOutcomes que contemplam conceitos de avaliação de instrumentos para apreciação de resultados relatados pelo paciente. Inicialmente são apresentados e discutidos os conceitos de confiabilidade, responsividade e interpretabilidade, citados exemplos das principais formas de avaliação dessas propriedades.Resultados: pode-se perceber que ainda há divergências em algumas descrições conceituais. Entretanto, os autores ressaltam a importância da confiabilidade para avaliar o instrumento de medida. Destaca-se a importância do conhecimento do Modelo Conceitual, das propriedades de medidas e dos diferentes métodos de avaliação para garantir, principalmente em estudo de validação de instrumentos, resultados confiáveis e válidos.Conclusões: a discussão apresentada sobre a confiabilidade, responsividade e interpretabilidade contribui para os profissionais de saúde no conhecimento teórico e senso crítico na escolha de instrumentos e na condução de análises sobre essas propriedades de medida. DESCRITORES:Confiabilidade dos dados. Psicometria. Estudos de validação. Inquéritos e questionários. Precisão da medição dimensio...
