To validate the Birth Beliefs Scale (BBS) for maternity care professionals by testing: (1) content validity; (2) internal reliability; (3) known-group discriminant validity; and examine potential relationships between regions and birth beliefs.
First, content validity was tested. Before distribution of the questionnaire among maternity care professionals of six maternity care networks (MCNs), adjustments in the statements were made whenever content validity was too low. Data were collected from November 2022 to March 2023. Statistical analysis was performed using Cronbach's alpha, ANOVA and regression analysis.
Based on the content validity-test, item 6 of the questionnaire was adjusted before distribution. In total, 199 maternity care professionals completed the questionnaire. A good internal reliability of the BBS was found. There was a significant difference between the different disciplines for the BBS-Med subscale ( < .001), and the BBS-Nat subscale ( < .001). For the BBS-Nat subscale, the factors work experience and MCN were significant in the regression analysis, with interaction on the association between BBS-Nat and discipline.
The BBS is a valid instrument to measure birth beliefs among maternity care professionals. The BBS can help to create awareness within professionals of their beliefs and may help to explain practice variation in childbirth.
通过测试（1）内容效度；（2）内部一致性；（3）已知组判别效度，来验证针对产科护理专业人员的生育信念量表（BBS）。并检查区域与生育信念之间的潜在关系。
首先，测试内容效度。在向六个产妇护理网络（MCN）的产科护理专业人员分发问卷之前，只要内容效度太低，就会对陈述进行调整。数据收集于 2022 年 11 月至 2023 年 3 月进行。使用 Cronbach's alpha、方差分析和回归分析进行统计分析。
根据内容效度测试，在分发问卷前对问卷的第 6 项进行了调整。共有 199 名产科护理专业人员完成了问卷。BBS 具有良好的内部一致性。BBS-Med 分量表（<0.001）和 BBS-Nat 分量表（<0.001）在不同学科之间存在显著差异。对于 BBS-Nat 分量表，工作经验和 MCN 是回归分析中的重要因素，并且在 BBS-Nat 与学科之间的关联上存在交互作用。
BBS 是衡量产科护理专业人员生育信念的有效工具。BBS 可以帮助专业人员提高对自身信念的认识，并有助于解释分娩实践中的差异。
