BACKGROUND
Anxiety is one of the most prevalent mental health disorders among mothers during the postpartum period, which can lead to maternal and infant physical and psychological consequences. The Postpartum Specific Anxiety Scale (PSAS) predicts unique variance in postnatal outcomes over and above general anxiety tools. It has never been used in Iran and its validity and reliability have not been assessed either. Therefore, the present study aimed to translate and investigate the psychometric properties of the PSAS-IR.
METHODS
510 women, from six weeks to six months postpartum, were selected through random sampling in 2020. After forward and back-translation, the face validity, content validity, and construct validity of PSAS (through confirmatory factor analysis) were examined. The reliability of the scale was assessed using both internal consistency (Cronbach's alpha) and test-retest stability methods.
RESULTS
CVI and CVR values of the PSAS tool were 0.89 and 0.88, respectively. The good fit indices confirmed the validity of four-factor structure. Cronbach's alpha coefficient and Intra Correlation Coefficient (ICC) equaled 0.93 and 0.92, respectively.
CONCLUSION
The Persian version of PSAS is a valid and reliable four-factor scale, it will improve the measurement of postpartum anxiety in an Iranian setting. This will improve the measurement of postpartum anxiety in an Iranian setting.
背景
焦虑是产后母亲中最常见的心理健康障碍之一，可导致母婴身体和心理后果。产后特定焦虑量表（PSAS）预测了产后结局的独特差异，超过了一般焦虑工具。它从未在伊朗使用过，其有效性和可靠性也没有得到评估。因此，本研究旨在翻译并研究 PSAS-IR 的心理测量特性。
方法
2020 年，通过随机抽样，从产后 6 周到 6 个月期间，共选择了 510 名女性。经过正向和反向翻译，对 PSAS 的表面效度、内容效度和结构效度（通过验证性因素分析）进行了检验。使用内部一致性（克朗巴赫 α）和重测稳定性方法评估了量表的可靠性。
结果
PSAS 工具的 CVI 和 CVR 值分别为 0.89 和 0.88。良好的拟合指数证实了四因素结构的有效性。克朗巴赫 α系数和内相关系数（ICC）分别为 0.93 和 0.92。
结论
PSAS 的波斯语版本是一个有效且可靠的四因素量表，它将改善伊朗的产后焦虑测量。这将改善伊朗的产后焦虑测量。
