Translation, adaptation and psychometric validation of the preterm birth experience and satisfaction scale (P-BESS) into Spanish.

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. To translate, transculturally adapt and assess the psychometric properties of the P-BESS into Spanish. Cross-sectional study. Maternity unit of a tertiary level hospital in Spain. A total of 182 woman who gave birth before 37 weeks of gestation. 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). 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). The Spanish version of P-BESS appears to be a robust, valid and reliable instrument for assessing satisfaction with care during preterm birth. 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.

Cross-cultural adaptation and validation of the psychometric properties of the Quality from the Patient's Perspective I Questionnaire translated into Spanish.

translate the questionnaire Quality from the Patient's Perspective-Intrapartal (QPP-I) into Spanish, carrying out a cross-cultural adaptation and validation of its validity and reliability DESIGN: observational multi-centre transversal study, with transcultural adaptation and validation of a scale. the study was carried out in two public Spanish hospitals. 248 women in their postpartum period. the instrument was translated and back translated. Validity was determined in different ways: by comparing the QPP-I with an instrument which had already been validated (the COMFORTS scale); by carrying out an exploratory factor analysis by means of a principal component analysis (PCA), and by studying the relationship between the QPP-I and sociodemographic variables (level of studies, age, place of birth of the mother), clinical variables (number of children, type of childbirth, use of epidural, gestational age), positive feelings (control, pride, safety, being paid attention to) and negative feelings (failure, feeling ignored) experienced during childbirth, as well as physical and mental state as assessed by the woman. Reliability was estimated from the internal consistency, with the Cronbach's alpha (α), and the test-retest, with the intraclass correlation coefficient (ICC). eleven factors obtained an eigenvalue greater than the unit value in the PCA, explaining 70.5% of the total variance. A statistically significant association was found with the variables place of birth of the mother, level of studies, type of birth, positive and negative feelings during childbirth, and state of health of the mother. On comparing the QPP-I with the COMFORTS scale, the area under the received operating characteristic (ROC) curve was 0.824 (confidence interval of 95%, 0.764-0.884). For the total scale, the value of α was 0.96. The consistency ICC was 0.76 (CI 95%, 0.65-0.84) and the absolute agreement ICC was 0.76 (CI 95%, 0.66-0.84). the QPP-I with 39 items distributed among 11 factors seems adequate to measure women's satisfaction with the care received during childbirth in our setting. this tool can be used in both a clinical and a research setting for women to be able to evaluate the care they receive when they give birth. It is therefore a way of improving the care given to these users.

Psychometric properties of the modified breastfeeding self-efficacy scale-short form (BSES-SF) among Chinese mothers of preterm infants.

Preterm mother-infant dyads face more challenges than healthy term infants in breastfeeding initiation and continuation due to maternal health status, preterm infant's immaturity or comorbidities, and breastfeeding policy of the neonatal units. Breastfeeding self-efficacy affects breastfeeding outcomes in preterm infants. No specific instrument in Chinese is available to assess maternal breastfeeding self-efficacy of preterm infants. This study aims to assess the psychometric characteristics of the modified Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) among Chinese mothers of preterm infants. A cross-sectional study was conducted. Two tertiary hospitals in China. A total of 153 women who gave birth before 37 weeks of gestation. The instrument was translated and back translated. The internal consistency reliability was investigated using Cronbach's alpha coefficient. The content validity, construct validity, and criterion validity were conducted to evaluate the validity of the scale. Exploratory factor analysis was used to investigate the factor structure. The scale had good reliability with Cronbach´s alpha above the acceptable level of 0.7. The Item-Content Validity Index (I-CVI) ranged from 0.800 to 1.000, and the Scale-Content Validity Index (S-CVI) is 0.950. The principal component analysis revealed the presence of two factors with eigenvalues greater than 1, explaining a total variance of 74.665%. The modified BSES-SF scores were correlated with women's parity, breastfeeding knowledge, previous breastfeeding experience, perceived support from the spouse and health professionals, and amounts of expressed milk. The Chinese version of modified BSES-SF is a reliable, valid screening instrument to evaluate the maternal breastfeeding self-efficacy of preterm infants. It is recommended to provide interactive, face-to-face breasting education and support to help mothers of preterm infants maintain high level of breastfeeding self-efficacy and further to achieve satisfactory breastfeeding outcomes.

Spanish validation and factor structure of the Birth Satisfaction Scale-Revised (BSS-R).

To translate and validate a Spanish-language version of the Birth Satisfaction Scale-Revised (BSS-R) and describe key measurement properties. A cross-sectional instrument validation design examining factor structure, validity and reliability. Three public hospital sites in Spain. 202 women who had given birth within the past four weeks provided complete questionnaire data for analysis. Measures included the Spanish version of the BSS-R (S-BSS-R) and the Perceived Stress Scale (PSS). The tri-dimensional measurement model of the BSS-R was found to offer a good fit to Spanish data. Known-groups discriminant validity was found to be excellent with women experiencing a non-intervention delivery having higher S-BSS-R scores (p < 0.05) compared to those having an intervention. Women who had no pain control were found to have greater S-BSS-R total and S-BSS-R women's attributes and stress experienced sub-scale scores compared to those who received pain control (p < 0.05). Total scale internal reliability was also found to be acceptable. Evidence for good divergent and convergent validity was also found across total and sub-scale S-BSS-R scores. The S-BSS-R was found to have generally good to excellent psychometric properties and represents a valid and reliable translation of the original version of the BSS-R for use in Spanish-speaking populations. The development of the S-BSS-R enables comparison of birth satisfaction with international study data where the BSS-R is used. The relationship of both delivery type and pain control to birth satisfaction represent important areas for further research.
