To validate the Childbirth Experience Questionnaire 2 (CEQ2) in the UK to see if it is an effective tool for evaluating labour experience.
The CEQ2 and part of the Care Quality Commission Maternity Survey (2010) was sent to 475 women one month and six weeks after birth. It was tested for face validity among 25 postnatal mothers. Demographic data and delivery data was used to establish construct validity using the method of known-groups validation. The results of the scored CEQ2 sent out twice were used to measure test-retest reliability by calculating the quadratic weighted index of agreement between the two scores. Criterion validity was measured by calculating the Pearson correlation coefficient for the CEQ2 and Maternity Survey scores.
Face validity of the CEQ2 in a UK population was demonstrated with all respondents stating it was easy to understand and complete. A statistically significantly higher CEQ2 score for subgroups of women known to report a better birth outcome demonstrated construct validity. A weighted kappa of 0.55 demonstrated test-retest reliability. A Pearson correlation co-efficient of 0.56 demonstrated a moderate correlation between the results of the CEQ2 and the results of the 'gold standard' assessment of childbirth experience in the UK: the Maternity Survey and hence criterion validity.
This study demonstrates that the Childbirth Experience Questionnaire version 2 (CEQ2) is a valid and reliable measure of childbirth experience in the UK population.
在英国验证分娩体验问卷2（CEQ2），以确定其是否为评估分娩经历的有效工具。
在产后1个月和6周时，将CEQ2及部分护理质量委员会产妇调查（2010年）问卷发送给475名女性。在25名产后母亲中对其表面效度进行了测试。使用已知群组验证方法，利用人口统计学数据和分娩数据来确定结构效度。通过计算两次发出的CEQ2评分结果之间的二次加权一致性指数，来测量重测信度。通过计算CEQ2与产妇调查得分之间的皮尔逊相关系数来测量效标效度。
CEQ2在英国人群中的表面效度得到了证明，所有受访者均表示该问卷易于理解和填写。已知报告分娩结局较好的女性亚组的CEQ2得分在统计学上显著更高，证明了结构效度。加权kappa值为0.55，证明了重测信度。皮尔逊相关系数为0.56，表明CEQ2结果与英国分娩体验“金标准”评估（产妇调查）结果之间存在中度相关性，从而证明了效标效度。
本研究表明，分娩体验问卷第2版（CEQ2）是衡量英国人群分娩体验的有效且可靠的工具。
