Objective. This study aims to develop a Portuguese-language version of the Birth Satisfaction Scale-Revised (BSS-R) for clinical and research use in Portugal (PT-BSS-R). The factor structure, its invariance across depression levels, and the internal consistency of the PT-BSS-R were analysed. Method. A sample of 1373 Portuguese-speaking postpartum women completed a sociodemographic and clinical form, the PT-BSS-R, and the Edinburgh Postnatal Depression Scale through an online survey tool. Four competing models were tested through confirmatory factor analyses and bifactor model-based psychometric indices were calculated. The internal consistency and the divergent/convergent validity were analysed. Results. The psychometric properties of the PT-BSS-R were found to be generally excellent. Both the original correlated three-factor model and the bifactor model exhibited a good fit to the data. Results from the bifactor model support the use of both the BSS-R total score and the subscale scores. Exemplary invariance findings were observed between groups stratified on the basis of a depression screening. The PT-BSS-R has demonstrated both divergent and convergent validity as well as internal consistency. Conclusion. The PT-BSS-R is a psychometrically robust measure of birth satisfaction appropriate for clinical and research use in Portugal.
