BACKGROUND Maternal mental health including postpartum mental health is essential to women's health. This study aimed to develop a specific measure for assessing postpartum depression literacy and consequently evaluate its psychometric properties among a sample of perinatal women. METHODS This investigation was composed of two studies: developing the measure, and evaluating of psychometric properties of the developed questionnaire. In development stage an item pool was created. Then, based on definition of mental health literacy and preliminary screening, an initial questionnaire was developed. The content and face validity of the questionnaire were then assessed. In the second study psychometric properties of the questionnaire were examined. Overall 692 perinatal women with the mean age of 27.63 years (ranging from 17 to 43) participated in the study. RESULTS In all an item pool of 86 items was generated. Of these, 31 items were removed and the remaining 55 items subjected to content and face validity and further 16 items removed. In the second stage a 39-item questionnaire namely the Postpartum Depression Literacy Scale (PoDLis) was evaluated. In principal component factor analysis, 31 items were loaded indicating a 7-factor solution for the questionnaire. The factors designated the following constructs: ability to recognize postpartum depression, knowledge of risk factors and causes, knowledge and belief of self-care activities, knowledge about professional help available, beliefs about professional help available, attitudes which facilitate recognition of postpartum depression and appropriate help-seeking, and knowledge of how to seek information related to postpartum depression. Finally performing the confirmatory factor analysis, the Postpartum Depression Literacy Scale with 31 items was supported for the structures suggested by theoretical model and findings from the exploratory factor analysis. The Cronbach's alpha coefficient for the scale was .78 and it ranged from .70 to .83 for each factor lending support to the internal consistency of the questionnaire. CONCLUSION The findings suggest that the Postpartum Depression Literacy Scale (PoDLiS) is a reliable and valid instrument for measuring the postpartum depression literacy and now can be used in studies of mental health literacy in women.

产后抑郁症识字量表（PoDLiS）：发展和心理测量特性。


背景技术孕产妇心理健康，包括产后心理健康，对女性健康至关重要。本研究旨在制定一种评估产后抑郁症素养的具体措施，从而评估其在围产期妇女样本中的心理测量特性。方法 这项调查由两项研究组成：制定测量方法，以及评估所制定问卷的心理测量特性。在开发阶段创建了一个项目池。然后，根据心理健康素养的定义和初步筛选，制定了初步调查问卷。然后评估问卷的内容和表面效度。在第二项研究中，检查了问卷的心理测量特性。共有 692 名围产期妇女参与了这项研究，平均年龄为 27.63 岁（范围从 17 岁到 43 岁）。结果 总共生成了 86 个项目的项目池。其中，31 项被删除，其余 55 项受到内容和表面有效性的影响，另外 16 项被删除。第二阶段评估了包含 39 项的问卷，即产后抑郁素养量表 (PoDLis)。在主成分因子分析中，加载了 31 个项目，表明问卷的 7 因子解决方案。这些因素指定了以下结构：识别产后抑郁症的能力、对危险因素和原因的了解、对自我护理活动的知识和信念、对可获得的专业帮助的了解、对可获得的专业帮助的信念、促进识别产后抑郁症的态度和适当的态度。寻求帮助，以及了解如何寻求与产后抑郁症相关的信息。 最后进行验证性因素分析，包含 31 个项目的产后抑郁素养量表得到了理论模型和探索性因素分析结果所建议的结构的支持。该量表的 Cronbach α 系数为 0.78，每个因子的范围为 0.70 至 0.83，支持问卷的内部一致性。结论 研究结果表明，产后抑郁素养量表（PoDLiS）是衡量产后抑郁素养的可靠有效的工具，现在可用于女性心理健康素养的研究。
