产后抑郁素养量表在孕产妇中的信效度检验

Reliability and Validity of the Postpartum Depression Literacy Scale among pregnant and postpartum women

目的 对产后抑郁素养量表进行汉化、文化调试及信效度检验。方法 翻译原量表的方法为正译、综合、回译、专家委员会等;量表的文化调适和内容效度评定通过认知性访谈及专家评议。便利选取2022年8月~11月北京市某三级甲等医院的284例孕产妇进行调查并评价量表的信效度;间隔2周后采用目的抽样法选取30例孕产妇对中文版产后抑郁素养量表(PoDLiS)量表进行重测信度检验。结果 中文版产后抑郁素养量表包含5个维度25个条目,分别是识别产后抑郁症的能力(6个条目)、对风险因素和原因的了解(4个条目)、自我照顾活动及获得专业帮助的知识和信念(6个条目)、有助于识别产后抑郁和适当寻求帮助的态度(4个条目)、如何寻求产后抑郁相关信息的知识(5个条目)。量表的5个维度的内容效度指数为0.78~1.00,平均内容效度指数为0.913;量表的Cronbach′s α系数为0.925,5个维度的Cronbach′s α系数为0.829~0.960;量表的重测信度为0.997,5个维度的重测信度为0.968~0.996。结论 中文版产后抑郁素养量表具有较好的信效度,可以评价孕产妇的产后抑郁素养,在临床中为孕产妇的健康教育及护理措施提供依据。

Objective The Postpartum Depression Literacy Scale(PoDLiS)was translated into Chinese,and its cultural adjustment,reliability and validity were tested.Methods The original scale was translated by the methods of forward translation,synthesis,back translation and expert committee review.The cultural adaptation and content validity of the scale were assessed through cognitive interview and expert review.A convenience sample of 284 pregnant and postpartum women from a tertiary hospital in Beijing from August to November 2022 were surveyed to assess the scale′s reliability and validity.A subset of 30 pregnant and postpartum women completed a test-retest reliability assessment of the Chinese version of the PoDLiS scale two weeks later.Results The Chinese version of PoDLiS consists of 5 dimensions(total 25 items),including the Ability to recognize postpartum depression(6 items),knowledge of risk factors and causes(4 items),knowledge and beliefs of self-care activities and professional help available(6 items),attitudes which facilitate recognition of postpartum depression and appropriate help-seeking(4 items),knowledge of how to seek information related to postpartum depression(5 items).The content validity index for the 5 dimensions ranged from 0.78 to 1.00,with an average content validity index of 0.913.The scale demonstrated a Cronbach′sαcoefficient of 0.925,with Cronbach′sαcoefficients for the 5 dimensions ranging from 0.829 to 0.960.The test-retest reliability coefficient was 0.997,with test-retest reliability coefficients for the 5 dimensions ranging from 0.968 to 0.996.Conclusion The Chinese version of the Postpartum Depression Literacy Scale demonstrates good reliability and validity among pregnant and postpartum women,providing a basis for health education and nursing interventions in clinical practice.
