Tools to evaluate pregnancy-specific anxiety are lacking in Japan. This study aimed to develop a Japanese version of the Pregnancy-Related Anxiety Questionnaire-Revised-2. After scale translation and cognitive interviews, we conducted a cross-sectional study among 120 ≥18-year-old, singleton (pregnant with one baby) Japanese women before 15 weeks of pregnancy, recruited from four facilities. A total of 112 women completed the questionnaires. We tested the internal consistency, measurement error and reliability, structural validity, measurement invariance across nulliparous and parous women, construct validity by calculating omega, standard error of measurement (SEM), intraclass correlation coefficient (ICC), confirmatory factor analysis (CFA), multigroup CFA, multitrait-scaling analysis, correlational analyses with other measurements, and -test to compare nulliparous and parous groups. Omega was 0.90 for the total score. SEM was 3.4 and ICC was 0.76. The CFA revealed an optimal fit for the three-factor model based on the original scale. Multigroup CFA supported measurement invariance across the nulliparous and parous groups, and multitrait-scaling analysis revealed 100% scaling success. The correlation coefficients with other scales of childbirth anxiety and general anxiety were 0.70 and 0.24. The mean total score of the nulliparous women was higher than that of the parous women (34.5 vs. 30.3, = 0.001). Therefore, the scale was determined to have good validity and reliability.
在日本，缺乏评估特定于孕期焦虑的工具。本研究旨在开发《孕期相关焦虑问卷修订版-2》的日文版。在进行量表翻译和认知访谈后，我们对从四个机构招募的120名年龄≥18岁、单胎（怀有一个婴儿）且处于孕15周前的日本女性进行了横断面研究。共有112名女性完成了问卷。我们测试了内部一致性、测量误差和信度、结构效度、未生育和已生育女性之间的测量不变性、通过计算欧米伽、测量标准误（SEM）、组内相关系数（ICC）、验证性因素分析（CFA）、多组CFA、多特质量表分析、与其他测量方法的相关性分析以及用于比较未生育和已生育组的检验。总分的欧米伽值为0.90。SEM为3.4，ICC为0.76。CFA显示基于原始量表的三因素模型拟合最佳。多组CFA支持未生育和已生育组之间的测量不变性，多特质量表分析显示量表成功比例为100%。与其他分娩焦虑和一般焦虑量表的相关系数分别为0.70和0.24。未生育女性的平均总分高于已生育女性（34.5对30.3，P = 0.001）。因此，该量表被确定具有良好的效度和信度。
