Abstract：
BACKGROUND: The purpose of this study was to explore the reliability and construct validity of the EPDS-US.
METHODS: To enhance the perinatal mental health screen, we adapted the Edinburgh Postnatal Depression Screen (EPDS) for application in the United States, and evaluated reliability and construct validity of the EPDS-US in a sample of 100 postpartum individuals. We explored reliability by estimating internal consistency of the scale and evaluating concurrent validity with correlations to the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Assessment (GAD-7); and construct validity using factor analysis and discriminant validity with correlations to the Perceived Stress Scale (PSS).
RESULTS: We present both a one-factor (Cronbach\'s alpha of 0.83) and two-factor model consisting of depressive (Cronbach\'s alpha 0.76) and anxiety symptoms (Cronbach\'s alpha 0.78) of the EPDS-US. Related to discriminant validity, the EPDS-US and PSS exhibited a moderate correlation of 0.71. For measures of concurrent validity, correlations with the PHQ-9 and GAD-7 were moderate; 0.63 and 0.68, respectively.
CONCLUSIONS: The EPDS-US was adapted to enhance the perinatal mental health screening experience for populations in the US while maintaining the reliability and validity of the original Edinburgh Postnatal Depression Scale. These findings contribute to the evidence of reliability and validity of the EPDS-US in perinatal populations in the United States; presenting initial evidence supporting construct validity and concurrent validity of this newly adapted 10-item scale.

摘要：
背景：本研究的目的是探索EPDS-US的信度和结构效度。
方法：为了加强围产期心理健康筛查，我们调整了爱丁堡产后抑郁症筛查（EPDS）在美国的应用，并评估了EPDS-US在100名产后个体样本中的信度和结构效度。我们通过评估量表的内部一致性并评估并发效度与患者健康问卷（PHQ-9）和广义焦虑症评估（GAD-7）的相关性来探索信度；并使用因子分析和判别效度与感知压力量表（PSS）的相关性来构建效度。
结果：我们提出了单因素模型（Cronbach的α为0.83）和双因素模型，包括EPDS-US的抑郁（Cronbach的α为0.76）和焦虑症状（Cronbach的α为0.78）。与判别效度有关，EPDS-US和PSS表现出0.71的中度相关性。对于并发有效性的度量，与PHQ-9和GAD-7的相关性中等；分别为0.63和0.68。
结论：EPDS-US适用于增强美国人群的围产期心理健康筛查体验，同时保持原始爱丁堡产后抑郁量表的信度和效度。这些发现为EPDS-US在美国围产期人群中的可靠性和有效性提供了证据；提出了支持这种新调整的10项量表的结构效度和并发效度的初步证据。
