The body image during pregnancy potentially affects both short- and long-term maternal and child health outcomes, including pregnancy mood, postpartum weight recovery, and the quality of mother-child interactions. However, research on the impact of body changes during pregnancy in the Chinese population is scarce. A comprehensive, practical, and reliable tool for assessing pregnant women is needed to detect, intervene in, and implement the reduction of physical dissatisfaction risk. This study translated the Prenatal Body Image Questionnaire (PBIQ) into the Chinese version (PBIQ-C) to assess the body image of pregnant women and evaluated its reliability and validity.
An improved Brislin translation model was used for the translation. A panel of experts determined the content validity. A convenience sample of 429 pregnant women was chosen from three third-class hospitals in different regions of Fujian Province, China. Factor analysis, Pearson's correlation, retest reliability, and Cronbach's alpha were employed to evaluate structural validity and reliability.
The final PBIQ-C had five dimensions with 21 items. Exploratory factor analysis obtained a five-factor solution, which accounted for a total of 60.34%. Confirmatory factor analysis showed that the model fit of the five-factor model also reached a satisfactory model fit after modifying: The Comparative Fit Index was 0.93, and the Tucker-Lewis Index was 0.92; the Root Mean Square Error of Approximation was 0.079. The content validity index of the scale ranged from 0.63 ~ 1.00. The Cronbach's alpha coefficient was 0.95 for the total scale, and the test-retest reliability was 0.80.
The findings indicated that the PBIQ-C is a valid and reliable instrument for assessing women's body image during pregnancy, which helps in the early identification of body dissatisfaction during pregnancy and enables the early prevention of postpartum depression.
孕期的身体意象可能会影响母婴短期和长期的健康结果，包括孕期情绪、产后体重恢复和母婴互动质量。然而，针对中国人群怀孕期间身体变化影响的研究很少。需要一种全面、实用和可靠的工具来评估孕妇，以便发现、干预和降低身体不满的风险。本研究将产前身体意象问卷（PBIQ）翻译为中文版本（PBIQ-C），以评估孕妇的身体意象，并评估其信度和效度。
采用改良 Brislin 翻译模型进行翻译。一组专家确定了内容效度。便利选取了来自中国福建省三个不同地区的三级医院的 429 名孕妇作为样本。采用因子分析、Pearson 相关、重测信度和 Cronbach's alpha 评估结构效度和信度。
最终的 PBIQ-C 有五个维度，共 21 个条目。探索性因子分析得出了五因素模型，共占 60.34%。验证性因子分析表明，在修正后，五因素模型的拟合度也达到了满意的模型拟合：比较拟合指数为 0.93，Tucker-Lewis 指数为 0.92；近似均方根误差为 0.079。量表的内容效度指数范围为 0.63~1.00。量表的 Cronbach's alpha 系数为 0.95，重测信度为 0.80。
研究结果表明，PBIQ-C 是评估孕妇身体意象的有效和可靠工具，有助于早期识别孕期身体不满，并早期预防产后抑郁。
