The objective of this study was to analyze the psychometric properties of the hospital birth satisfaction scale with data from the first follow-up interview of the Birth in Brazil survey. The 11 questions of the scale were asked by telephone up to six months after discharge in a stratified random sample of 16,109 women residing in all five regions of the country. The sample was randomly divided into two halves. Exploratory factor analysis (EFA) was applied to the first half in order to identify the scale's factorial structure. The scree plot suggested the scale to be one-dimensional. The EFA demonstrated a good fit of the one-dimensional model. Factor loadings were greater than 0.5 for all items, except for the mean time transpired between leaving the home and arriving at the maternity hospital, which was excluded from the next analysis. The confirmatory factor analysis applied to the sample's second half with the remaining ten items had a good fit and the factor loadings were > 0.50 with p-values < 0.001. The associations between birth satisfaction and the external variables, the mother's education level (standardized coefficient = 0.073; p = 0.035), private insurance (SC = 0.183; p < 0.001) and having a companion at some point during the hospitalization for labor (SC = 0.193; p = 0.001) were all as expected. There was evidence of configural and metric invariance according to type of hospital (private or public) and type of delivery (cesarean or vaginal). These results showed that the hospital birth satisfaction scale in Brazil is a one-dimensional instrument composed of ten items.
本研究旨在通过巴西生育调查的首次随访访谈数据，分析医院分娩满意度量表的心理测量特性。该量表的 11 个问题通过电话在出院后 6 个月内对居住在全国五个地区的 16109 名妇女进行分层随机抽样调查。样本随机分为两半。对前一半进行探索性因素分析（EFA），以确定量表的因子结构。陡坡图表明该量表为单维结构。EFA 表明一维模型拟合良好。除了离开家到到达妇产医院的平均时间（Mean time transpired between leaving the home and arriving at the maternity hospital）之外，所有项目的因子负荷均大于 0.5，该时间被排除在下一次分析之外。应用于样本另一半的剩余 10 个项目的验证性因素分析（CFA）拟合良好，因子负荷均大于 0.50，p 值均小于 0.001。分娩满意度与外部变量（母亲的教育水平（标准化系数= 0.073；p = 0.035）、私人保险（SC = 0.183；p < 0.001）和在分娩期间的某个时刻有陪伴者（SC = 0.193；p = 0.001）之间的关联均与预期相符。根据医院类型（私人或公共）和分娩类型（剖宫产或阴道分娩），存在结构和度量不变性的证据。这些结果表明，巴西的医院分娩满意度量表是一种由十个项目组成的一维工具。
