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 (α), 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 χ2(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.
Implications For Practice:
the instrument provides a more comprehensive understanding of this complex experience. It allows the detection of areas of intervention in order to empower strategies to cope with preterm births and to maximise feelings of self-confidence and control.

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
