BACKGROUND
The aim of the present work was to cross-culturally adapt the Postpartum Depression Literacy Scale (PoDLiS) and use a descriptive cross-sectional design to evaluate its psychometric properties in Chinese perinatal women.
METHODS
Brislin's translation theory was applied to translate the PoDLiS, with subsequent cultural adaptation. The reliability and validity of the PoDLiS were determined using a questionnaire in 635 Chinese perinatal women.
RESULTS
Good internal consistency was found (omega coefficient, 0.894) for the Chinese version of the Postpartum Depression Literacy Scale (PoDLiS-C), with omega coefficients of the six dimensions of 0.865, 0.870, 0.838, 0.777, 0.837 and 0.794, and a test-retest reliability coefficient of 0.874. The item-level content validity index (CVI) ranged from 0.8 to 1 while the scale-level CVI was 0.968. Moreover, confirmatory factor analysis (CFA) determined satisfactory construct validity of the PoDLiS-C, with the six-factor model explaining 60.76% of the total variance, demonstrating good model fit (likelihood ratio χ/df, 1.003; goodness-of-fit index, 0.916; adjusted goodness-of-fit index, 0.901; comparative fit index, 0.999; incremental fit index, 0.999; root mean square error of approximation, 0.003; and standardized root mean square error of approximation, 0.0478).
CONCLUSIONS
The PoDLiS-C has adequate psychometric properties. This tool could be used to assess the postpartum depression literacy of perinatal women in Chinese-speaking populations.
背景
本研究旨在跨文化调适产后抑郁知识量表（PoDLiS），并采用描述性横断面设计评估其在中国围产期女性中的心理测量学特性。
方法
采用 Brislin 翻译理论对 PoDLiS 进行翻译，并进行文化调适。使用问卷对 635 名中国围产期妇女进行调查，以确定 PoDLiS 的信度和效度。
结果
中文版产后抑郁知识量表（PoDLiS-C）具有良好的内部一致性（ω系数为 0.894），六个维度的 ω系数分别为 0.865、0.870、0.838、0.777、0.837 和 0.794，重测信度系数为 0.874。项目水平内容效度指数（CVI）范围为 0.8 至 1，而量表水平 CVI 为 0.968。此外，验证性因子分析（CFA）确定了 PoDLiS-C 的结构效度良好，六因素模型解释了总方差的 60.76%，表现出良好的模型拟合度（似然比 χ/df，1.003；拟合优度指数，0.916；调整拟合优度指数，0.901；比较拟合指数，0.999；增量拟合指数，0.999；近似均方根误差，0.003；标准化近似均方根误差，0.0478）。
结论
PoDLiS-C 具有良好的心理测量学特性。该工具可用于评估中国围产期妇女的产后抑郁知识水平。
