ABSTRACT

Objectives

To describe the translation and cultural adaptation, and evaluate the psychometric properties of the Body Image in Pregnancy Scale when applied to Brazilian pregnant women.

Background

Poor body image of pregnant women is associated with negative outcomes for maternal and child health. However, there is a lack of psychometric studies aiming to evaluate the body image experiences during pregnancy.

Methods

A methodological study was carried out with 187 Brazilian pregnant women. We performed translation and cross-cultural adaptation (evidence of content validity), and evaluated the psychometric properties (factorial validity through principal component analysis, discriminant validity, and estimated internal consistency) of the Brazilian version of the Body Image in Pregnancy Scale.

Results

The scale items presented semantic, idiomatic, cultural, and conceptual equivalences, showing evidence of content validity. Principal component analysis resulted in a 6-factor structure with 35 items which showed an adequate adjustment of the scale among Brazilian pregnant women. Adequate estimated internal consistency (Cronbach’s α = .88) was found. The Brazilian version was not able to discriminate pregnant women from different gestational age.

Conclusion

The Brazilian version of the Body Image in Pregnancy Scale showed evidence of content validity, factorial validity, and estimated internal consistency.

巴西版妊娠量表体象的效度和信度

摘要

目标

描述翻译和文化适应，并评估怀孕量表中身体形象应用于巴西孕妇时的心理测量特性。

背景

孕妇身体形象不佳与母婴健康的负面结果有关。然而，缺乏旨在评估怀孕期间身体形象体验的心理测量学研究。

方法

对 187 名巴西孕妇进行了一项方法学研究。我们进行了翻译和跨文化适应（内容有效性的证据），并评估了巴西版怀孕量表中身体形象的心理测量特性（通过主成分分析、区分有效性和估计的内部一致性的因子有效性）。

结果

量表项目呈现语义、惯用语、文化和概念等价，显示内容有效性的证据。主成分分析的结果是一个包含 35 个项目的 6 因素结构，表明巴西孕妇的量表调整得当。发现了足够的估计内部一致性（Cronbach's α  = .88）。巴西版本无法区分不同胎龄的孕妇。

结论

巴西版的怀孕量表身体形象显示了内容效度、因子效度和估计的内部一致性的证据。
