ABSTRACT Objective: to create a scale for assessing the adherence of healthcare providers to good practices for COVID-19 in the hospital setting and determine its content and face validity. Methods: A methodological study was developed in three sequential phases: creation of items and domains based on a literature review and administration of the questionnaire to 16 nursing professionals; assessment of content and face validity by experts; and semantic analysis. Results: The 51-item scale was submitted to the evaluation of seven experts. Items with a content validity index ≥ 0.83 were maintained. During the semantic analysis performed by the administration of the scale to 37 healthcare providers, no suggestions for changes were made and the comprehension rate was 87%. Conclusions: the 47-item instrument with three dimensions (personal, organizational, and psychosocial) achieved satisfactory content and face validity, meeting the parameters established in the literature.

O presente estudo destinou-se à construção e validação de uma escala de atitudes de professores de Estatística em relação à Estatística em cursos de Graduação no Brasil. A validação da Escala de Atitudes de professores de Estatística em relação à Estatística (EAPE) contou com uma amostra de 87 professores de sete estados brasileiros (Distrito Federal, Rio Grande do Sul, Paraná, Santa Catarina, São Paulo, Rio de Janeiro e Minas Gerais), de instituições de Ensino Superior públicas e privadas. Foi realizada análise fatorial experimental para a verificação da dimensionalidade da EAPE, sendo a solução de quatro fatores considerada a mais adequada. Os fatores extraídos foram denominados cognitivo, educativo, afetivo/social e de conduta, com alfas de Cronbach de 0,65; 0,68; 0,51 e 0,63, respectivamente. A escala geral apresentou uma consistência interna de 0,76.This study aimed to build and validate a scale of attitudes of teachers of Statistics towards Statistics in the Graduate courses in Brazil. The validation of the scale of attitudes of teachers of Statistics in relation to Statistics (EAPE) had a sample of 87 teachers from seven Brazilian states (Distrito Federal, Rio Grande do Sul, Paraná, Santa Catarina, São Paulo, Rio de Janeiro and Minas Gerais) from institutions of higher education both public and private. Factor analysis was performed for the experimental verification of dimensionality of EAPE, andfour factors were considered most appropriate. The factors taken were called cognitive, educational, emotional/social and conduct, with the Cronbach alphas of 0.65, 0.68, 0.51 and 0.63, respectively. The scale showed a general internal consistency of 0.76.

ABSTRACT Objectives: to assess the reliability and validity of the 46 items version of the comfort scale for family members of people in critical condition. Methods: a methodological study, carried out with 278 family members of critically ill patients, admitted to adult and pediatric intensive care units, in a city in the interior of the state of São Paulo, in Brazil. The analyzes were based on the Classical Test Theory and Item Response Theory. Results: Horn’s parallel analysis and exploratory and confirmatory factor analysis did not identify the scale’s unidimensionality nor the tridimensionality. The maximum factor loads were positive. The scale proved to be reliable (α=0.93 and Ω=0.63), most item-total correlations were greater than 0.28 and the discrimination coefficients were greater than one. Conclusions: the scale showed satisfactory reliability and relative construct validity. However, the recommended tridimensional structure for the scale has not been confirmed.
