Reliability and validity of the reduced Spanish version of the Prenatal Breastfeeding Self-Efficacy Scale: A longitudinal instrumental study

Breastfeeding self-efficacy is a relevant predictor of exclusive breastfeeding during the first six months of life. The Prenatal Breastfeeding Self-Efficacy Scale (PBSES) is a 20-item tool developed to determine breastfeeding self-efficacy during pregnancy. Our study aimed to assess the structural v...

The Prenatal Breastfeeding Self-Efficacy Scale (PBSES) is a 20-item tool developed to determine breastfeeding self-efficacy during pregnancy. Our study aimed to assess the structural validity and psychometric characteristics of the PBSES and to explore item reduction according to the statistical criteria for parsimony and incremental validity. In this study, conducted in six hospitals in eastern Spain, we recruited 1183 women with healthy, full-term, single-birth newborns. Data on sociodemographic, breastfeeding-related variables, and the PBSES, were obtained from self-administered questionnaires during the third trimester of pregnancy, at postpartum discharge, and 5 months postpartum, and from a phone survey 12 months postpartum. Item reduction was conducted after revising the PBSES item floor and ceiling effects, interitem correlations, and item-score relationships with breastfeeding-status variables during follow-up.

Internal consistency was measured using the Cronbach's alpha coefficient of the PBSES-SF (0.86). We provided evidence on the discriminant validity of the PBSES-SF by comparing its scores between known groups, convergent validity by examining its correlations with other variables, and predictive validity by assessing the association of PBSES-SF scores with breastfeeding behavior at critical points in time during the first postpartum year.John Wiley & Sons Inc.2021info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://fisabio.portalinvestigacion.com/publicaciones/12018RESEARCH IN NURSING & HEALTHISSN: 1098240XISSNe: 01606891reponame:r-FISABIO.
