RESUMEN
The Body Understanding Measure for Pregnancy Scale (BUMPs) is a scale developed and validated for British pregnant women to assess body satisfaction during pregnancy. The aim of this study was to perform a cross-cultural adaptation and verify the psychometric properties of BUMPs for Brazilian adult pregnant women. The cross-cultural adaptation was performed using translation, back-translation, expert committee, expert analysis, and pre-testing, which showed easy comprehension by pregnant women. Psychometric analyses were evaluated in a sample of 618 pregnant women (31.08 ± 4.94 years old). Exploratory and confirmatory factor analyses resulted in 19 items and three factors, with satisfactory fit indices. BUMPs presented an invariant measurement across white vs. nonwhite women and across the three gestational trimesters. BUMPs showed good indicators of convergent, internal consistency, and test-retest reproducibility validity. It was concluded that the Brazilian version of BUMPs has adequate psychometric properties for Brazilian pregnant women, being an excellent instrument for analyzing body satisfaction in this population, facilitating additional investigations into these constructs.
