Abstract Objective: To validate the Family Health Behavior Scale (FHBS) for Brazilian families. Methods: The sample included 272 children aged 5 to 12 years old. Caregivers and their healthy answered the FHBS and questions about physical activity. In addition, anthropometric measurements of the children’s weight and height were performed, as well as the bioimpedance exam. The scale was translated and the following validities were assessed: content (qualitative analysis and content validity index), construct (factor analysis) and concurrent validity (difference between domains and the total score with the categories of BMI, fat percentage and physical activity). Reliability (Cronbach's alpha, ceiling-floor effect, two-half test, intraclass correlation and Bland – Altman) was also assessed. Results: FHBS instrument performed well with regard to the psychometric properties in the Brazilian population. The content validity index was 0.987. Fit indices of the factor analysis were considered satisfactory, according to Bartlett's sphericity test (χ 2 = 1927, df = 351; p < 0.001) and the Kaiser-Meyer-Olkin index (KMO = 0.789). Concurrent validity, the differences between the mean of the domains and the total score between the categories of BMI (p = 0.011), percentage of fat (0.004) and physical activity (p < 0.001) were all significant. The reliability results were Cronbach's alpha internal consistency = 0.83, adequate ceiling-floor effect, 0.8105 (0.09 SD) two-half test, 0.626 intraclass correlation (95% CI: 0.406 to 0.777) and Bland – Altman -0.840 (-22.76 to 21.07). Conclusion: The FHBS adapted for the Brazilian population showed evidence of adequate psychometric performance.

RESUMO Objetivo O estudo tem como objetivo avaliar o desempenho do questionário de avaliação das disciplinas da Faculdade de Medicina da Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS Famed) em relação às propriedades psicométricas de validade e confiabilidade. Métodos Estudo transversal, exploratório e contemporâneo, com avaliação qualitativa e quantitativa. As disciplinas foram avaliadas pelos alunos de forma anônima, opcional e individual durante um período de aula de grande grupo logo após a conclusão das mesmas. Foram incluídos os questionários respondidos por acadêmicos matriculados entre o primeiro e o oitavo semestre e registrados nas atas finais da unidade, nas 22 disciplinas do currículo, no ano de 2011, que aceitaram realizar a avaliação da disciplina. Resultados Foram estudadas 1.205 respostas de um total possível de 1.606 alunos matriculados. A validação convergente demonstrou forte correlação entre o escore total de satisfação e os campos quantitativos correspondentes. A confiabilidade demonstrou um valor de alfa de Cronbach de 0,753 no escore total. Conclusão O estudo mostrou que o questionário de avaliação de disciplinas é válido e confiável.

ABSTRACT Aim The study aims to evaluate a questionnaire on the subjects taught at the Faculty of Medicine of the Pontifical Catholic University of Rio Grande do Sul (PUCRS), in terms of the psychometric properties of validity and reliability. Methods A cross-sectional, exploratory, and contemporary study was conducted using qualitative and quantitative evaluation. The subjects were evaluated by the students in an anonymous, optional and individual fashion during a large group class. The questionnaires were answered by PUCRS academics enrolled on the I-VIII semesters in 2011, who agreed to perform the evaluation immediately after completing the subject and who were registered in the final minutes for the units of the 22 subjects available. Results 1,205 responses were studied out of a possible 1,606 students enrolled on the course. The convergent validation demonstrated a strong correlation between the total score for satisfaction and the quantitative fields. Reliability demonstrated Cronbach alpha from the total score of 0.753. Conclusion The study showed that the questionnaire for subject evaluation is valid and reliable.
