Abstract

Background: Preterm labour and birth are two of the most important issues in perinatal care. The birth of a preterm baby is often a stressful and traumatic time for parents. Assessment of satisfaction with maternity services is crucial and questionnaires are the most common method as long as they are well-constructed. Only one, The Preterm Birth Experience and Satisfaction Scale (P-BESS), developed in United Kingdom, has been designed for this specific birth type. Objectives: To translate, transculturally adapt and assess the psychometric properties of the P-BESS into Spanish. Design: Cross-sectional study. Setting: Maternity unit of a tertiary level hospital in Spain. Participants: A total of 182 woman who gave birth before 37 weeks of gestation. Methods: The instrument was translated and back translated. The P-BESS was tested for face validity and construct validity by carrying out an exploratory/confirmatory factor analysis. Reliability was estimated from the internal consistency, with the Cronbach's alpha (alpha), and the test-retest, with the intraclass correlation coefficient (ICC). Findings: The principal component analysis revealed the presence of three factors with eigenvalues greater than 1, explaining a total variance of 66.6%. A subsequent varimax rotation revealed the presence of strong loadings on each of the three components. Confirmatory factor analysis was performed, offering the model a very good fit to the data: chi-square was chi(2)((df=149))=362.727 (p = 0.000); the root mean square error of approximation (RMSEA) = 0.089; the normed fix index (NFI) = 0.852 and the comparative fit index (CFI) = 0.905. The total scale and subscales had good reliability with all Cronbach's alpha above the acceptable level of 0.7. The total ICC was 0.994 (CI 95%, 0.988-0.997). Conclusions: The Spanish version of P-BESS appears to be a robust, valid and reliable instrument for assessing satisfaction with care during preterm birth.
