分娩态度量表的修订与信效度研究

Revision and Psychometric Testing of Childbirth Attitudes Questionnaire

目的对中文版分娩态度量表(childbirth attitudes questionnaire,CAQ)进行修订并检验。方法2020年6月,采取便利抽样的方法选取在福建省福州市三所医院进行产检的621名孕晚期孕妇作为研究对象,采用一般资料问卷、CAQ量表及分娩恐惧量尺(fear of childbirth scale,FOBS)对其进行调查,应用因子分析结合Rasch分析法修订CAQ并检验修订版CAQ的信效度。结果主成分分析结果显示,CAQ满足单维度标准,经Rasch分析和因子分析,删除2个条目,形成14个条目的修订版CAQ。验证性因子分析显示,修订版CAQ模型拟合理想;Rasch分析显示,修订版CAQ的个体分割指数和项目分割指数分别为2.88和9.50,个体信度和项目信度分别为0.89和0.99;Cronbach’sα系数为0.92,重测信度系数为0.82;校标关联效度为0.55(P<0.01),已知组别效度显示,初产妇、有剖宫产倾向的孕妇得分更高(t=-2.01~2.05,P<0.05)。结论修订版CAQ信效度良好,可作为评估孕晚期女性分娩恐惧的有效工具。

Objective To revised and tested the reliability and validity of the Chinese version of the Childbirth Attitudes Questionnaire(CAQ).Methods In June 2020,621 pregnant women in the third trimester of pregnancy who underwent prenatal examination in three hospitals in Fuzhou,Fujian Province were selected as the research objects.They were investigated by general data questionnaire,CAQ scale and fear of childbirth scale(FOBS)were used.The CAQ was revised by factor analysis combined with Rasch analysis,and the reliability and validity of the revised CAQ were tested.Results The principal component analysis showed that the CAQ met the unidimensional criteria.After the factor analysis and Rasch analysis,two items were removed,and a total of 14 items were retained to form the revised CAQ.Confirmatory factor analysis indicated the one-factor model had good fitting indexes.The person and item separation indices were 2.88 and 9.50,respectively.The person and item reliability indices were 0.89 and 0.99,respectively.The Cronbach’sαcoefficient of the scale was 0.92,and the retest reliability was 0.82.The Pearson correlation coefficient of criterion validity was 0.55(P<0.01).The known-groups validity showed that the primipara group and the cesarean-section-preference group got higher scores on the revised CAQ.(t=-2.01 to 2.05,P<0.05).Conclusions The revised CAQ has good reliability and validity and can be used as an effective assessment tool to evaluate the fear of childbirth of women in late pregnancy.
