Postpartum depression is a global phenomenon.
The purpose of this study was to develop and psychometrically evaluate the Spanish version of the Postpartum Depression Screening Scale (PDSS).
Eight translators representing the predominant Hispanic groups in the United States translated the PDSS into a Spanish version. A total of 377 Hispanic mothers completed the PDSS-Spanish Version within 12 weeks postpartum at two sites: Connecticut and Texas. Confirmatory factor analysis and item response theory analysis were conducted to assess construct validity.
For the total sample of 377 Hispanic women, the alpha reliability for the total PDSS was.95; dimension-level alphas ranged from.76 to.90. The total PDSS alphas by group were as follows: .94 (Mexican), .96 (Puerto Rican), and .93 (Other). Confirmatory factor analysis provided empirical support for the existence of the hypothesized constructs assessed by the PDSS. Item response theory analysis supported the adequacy of the construct definitions and confirmed that the response options for the Likert categories were an "ordered" attitude continuum in which higher responses corresponded to higher levels of "agreement" with the depressive symptomatology items.
When compared to the original English PDSS, the reliability and validity psychometrics for the Spanish version were slightly lower, but still within the acceptable range.
产后抑郁症是一种全球现象。
本研究的目的是开发产后抑郁筛查量表（PDSS）西班牙语版并对其进行心理测量学评估。
八名代表美国主要西班牙裔群体的翻译人员将PDSS翻译成西班牙语版。共有377名西班牙裔母亲在产后12周内于两个地点（康涅狄格州和得克萨斯州）完成了PDSS西班牙语版。进行验证性因素分析和项目反应理论分析以评估结构效度。
对于377名西班牙裔女性的总样本，PDSS总分的α信度为0.95；维度水平的α系数范围为0.76至0.90。按组划分的PDSS总分α系数如下：墨西哥裔为0.94，波多黎各裔为0.96，其他裔为0.93。验证性因素分析为PDSS评估的假设结构的存在提供了实证支持。项目反应理论分析支持结构定义的充分性，并确认李克特类别中的反应选项是一个“有序”的态度连续体，其中更高的反应对应于对抑郁症状项目更高水平的“认同”。
与原始英文PDSS相比，西班牙语版的信度和效度心理测量学指标略低，但仍在可接受范围内。
