Women's satisfaction with maternity care is strongly influenced by their sociodemographic characteristics, values, and attitudes. The arrival of a preterm baby is often a traumatic time, with unique factors involved. The Spanish Preterm Birth Experience and Satisfaction Scale (P-BESS) is a robust instrument capable of assessing women's satisfaction during preterm birth. The purpose of this study was to assess women's satisfaction with maternity care during labor and birth with preterm babies in a Spanish-speaking population. This is a cross-sectional study. Participants were 182 women who gave birth within 37weeks' gestation. Factors associated with satisfaction were studied through univariate and bivariate analyses and through multiple linear regression using the backward elimination method. Women reported high satisfaction with maternity care overall (average score of 84 out of 95). Women with a university education were generally less satisfied. Women were more satisfied if they were pregnant for the first time. Women who reported a previous premature birth or neonatal death were more satisfied, and women who had prior miscarriages were less satisfied compared with women without these experiences. The analysis confirmed that the majority of women surveyed were very satisfied with their childbirth experience. The Spanish P-BESS can be a useful way of prioritizing intervention measures, focusing on those aspects lowest scored by women, such as "information and explanations" and "confidence in staff," to improve maternity services for families experiencing preterm birth.
