Resumen
OBJECTIVE: To translate and to observe the psychometric measures of the Brazilian version
of the Quality of Prenatal Care Questionnaire.
METHODS: Th e t ranslation p rotocol f ollowed t he s tandards o f t he I nternational S ociety
for Pharmacoeconomics and Outcomes Research. Descriptive statistics were performed to
identify characteristics of 280 literate postpartum women in a public hospital. We examined
the internal consistency using Cronbach’s alfa. To determine the test-retest reproducibility and
the instrument’s stability, we performed the intraclass correlation coefficient and Bland and
Altman plot between two applications. We investigated the item’s properties using the item
response theory.
RESULTS: The overall Cronbach’s alpha index was 0.975. The intraclass correlation coefficient
was 0.995 (95%CI 0.993–0.996) and a uniform distribution was visualized at the Bland and
Altman plot. The item response theory identified the discriminatory power and the difficulty level
of the instrument and of each item. The instrument showed acute angulation of the expected
total score, and good concentrate information and good standard error curves, preserving the
latent construct and its original items.
CONCLUSIONS: This analysis concluded that the Brazilian version of the Quality of
Prenatal Care Questionnaire is a high-quality, reliable and valid questionnaire to determine
the quality of prenatal care among Brazilian women. The questionnaire is suitable for the
cultural context represented. Capes/Ministério da Educação. Código 001
