“…3,27 In the intrarater measurement, reliability is obtained by the classification or measurement of the same observer on two different occasions. 6 With the test-retest application, it is possible to verify the stability and reproducibility of the measurement. 3 However, there are reservations about its use considering the nature of the investigated variable, social desirability and memory that may influence the responses of the second measurement.…”

“…In the literature, it is recommended that the researchers of methodological studies describe at least one measurement error in the tested instrument. 6 Measurement errors reflect reduced reliability, however, reliability can be reasonably high even when the measurement error is not acceptable. Inversely, low measurement errors do not guarantee a reliable measurement parameter.…”

“…Many authors still do not consider it as a psychometric property; however, in the current classifications, the importance of this measure to evaluate the validity of changing scores is emphazied. 1,3,6 Several methods have been used to evaluate instrument or construct responsiveness. In the literature, a division between criteria-based approach has been observed, through the criterionshifting method and global scale of evaluation; and, construct-based approach, 6 with the use of t-test, effect size, mean standard response, and Guyatts responsiveness index.…”

“…5 The most valued measurement properties are usually the validity and reliability of the instrument. 6 Validity refers to the quality of an instrument to measure the construct for which it was constructed, while reliability relates to the degree to which an instrument permits reproduction and consistency of results when applied at different times. 4,7 In addition, other authors have described that, in addition to the two properties mentioned above, the quality of instrument measurement can be evaluated by the responsiveness that is defined as the instrument's ability to detect changes in patients' health status over time.…”

“…4,7 In addition, other authors have described that, in addition to the two properties mentioned above, the quality of instrument measurement can be evaluated by the responsiveness that is defined as the instrument's ability to detect changes in patients' health status over time. 6,8 The adaptationof instruments for the evaluation of subjective constructs,for different languages and cultures, has also been the subject of a large number of investigations, including discussions on the appropriate methodological process to ensure that the instrument preserves its properties of validity and reliability after adaptation. 1 In the last decade, this type of research has produced a considerable number of nursing researches, [9][10][11][12][13] reflecting the concern of these professionals to identify the most appropriate measurement instrument for a given situation or condition, considering the one that addresses the monitoring of patients in clinical practice and that contemplates the perception of the individuals themselves in the evaluation of their state of health.…”

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.

Validation and psychometric properties of the Farsi version of the fear of COVID‐19 scale among pregnant women

et al. 2022

Objective:The Covid-19 epidemic, which has become the most challenging issue for health organizations and governments, has led to panic among people, especially pregnant women. The aim of this study was to investigate the psychometric properties of the Persian version of the Fear of COVID-19 Scale (FCV-19S) on a sample of Iranian pregnant women. Methods:This cross-sectional study was performed on 500 pregnant women referred to gynecology offices in Tehran. Construct validity was performed using exploratory (with maximum likelihood method and Promax rotation) and confirmatory factor analysis. Cronbach's alpha and McDonald omega coefficients were used to examine internal consistency. Results:The mean age of the women was 28.98 (SD = 5.86) years. In exploratory factor analysis, two factors were extracted-emotional response and physiological response, which together explained 65.21% of the total variance of fear of Covid-19. In the confirmatory factor analysis, the final model had a good fit: CMIN/df = 1.515, goodness of fit index (GFI) = 0.981, adjusted goodness of fit index (AGFI) = 0.956, normed fit index (NFI) = 0.979, Incremental Fit Index (IFI) = 0.993, comparative fit index (CFI) = 0.993, and root mean square error of approximation (RMSEA) = 0.045 (95% CI: 0.001-0.085).Cronbach alpha and McDonald omega coefficients for the first factor were 0.874 and 0.878, and for the second factor were 0.853 and 0.854, respectively. Conclusion:The FCV-19S in pregnant women has a good construct validity and can be used in various studies.
