Abstract:

Objective To develop a Psychological Birth Trauma Assessment Scale and to test its reliability and validity. Methods Through literature review，semi-structured interview，expert conference，Delphi expert enquiry and preliminary investigation，a pre-test scale was formed. From March to May 2023，postpartum women from 38 hospitals of different levels in 15 provinces（Jiangsu，Anhui，Zhejiang，Fujian，Tibet，and Shanghai，etc.） were conveniently selected for investigation. The sample size of the first-round survey was 547，which was used for reliability and validity test. The sample size of the second-round survey was 550，which was used for confirmatory factor analysis. Results The psychological birth trauma assessment scale consisted of 2 parts，with a total of 29 items in 6 dimensions. The intrapartum feeling part included 4 dimensions，with a cumulative variance contribution rate of 63.992%，and the postpartum effect part included 2 dimensions，with a cumulative variance contribution rate of 68.208%. The content validity index of the scale was 0.947，and the content validity index of each item was 0.809~1.000. The total score of the scale and the scores of each dimension were significantly negatively correlated with the total score of the calibration scale（r=-0.784~-0.533，P<0.001）. The total Cronbach’s α coefficient was 0.941，and the split-half reliability coefficient was 0.883. Confirmatory factor analysis showed that the main evaluation indicators were all within the acceptable range. Conclusion The Psychological Birth Trauma Assessment Scale has good reliability and validity，and it can be used as an assessment tool for the degree of maternal psychological birth trauma.

摘要：

目的 编制分娩心理创伤评估量表，并检验其信效度。方法 通过文献回顾、半结构式访谈、专家会议、德尔菲专家函询及预调查形成预试量表。于2023年3月—5月，便利选取在江苏省、安徽省、浙江省、福建省、西藏自治区、上海市等15个省（区、市）共38所医院就诊的产妇进行调查。第1轮调查547名产妇，用于信效度检验；第2轮调查550名产妇，用于验证性因子分析。结果 分娩心理创伤评估量表包括2个部分、6个维度，共29个条目，其中，产时感受部分包含4个维度，累计方差贡献率为63.992%，产后效应部分包含2个维度，累计方差贡献率为68.208%。量表水平的内容效度指数为0.947，各条目水平的内容效度指数为0.809~1.000。总量表及各维度得分与校标量表总分均呈显著负相关（r=-0.784~-0.533，P<0.001）。总量表的Cronbach’s α系数为0.941，折半信度系数为0.883。验证性因子分析结果显示，主要评价指标均在可接受范围。结论 分娩心理创伤评估量表信效度良好，可作为测评产妇分娩心理创伤程度的有效工具。
