Adaptation and validation of the Portuguese version of the provider attitudes towards planned home birth (PAPHB) Scale

Abstract

Maternity health care professionals’ attitudes on the option of home birth can influence the choices and decisions women and their partners make about place of birth. Midwives are particularly influential in this space. The study outlined in this paper aimed to translate and validate the Provider Attitudes towards Planned Home Birth (PAPHB) scale questionnaire for use in the Portuguese maternity context. Methods: A total of 118 Portuguese midwives were selected through intentional sampling. The procedure was divided into two phases. In the first phase, a triple translation from the original language into Portuguese and a cross-cultural adaptation of the Provider Attitudes towards Planned Home Birth (PAPHB) scale were carried out, obtaining three versions of the same questionnaire. The second phase consisted of the validation of the questionnaire, for which the Provider Attitudes towards Planned Home Birth (PAPHB) scale was submitted to a panel of 20 experts and to a pilot test. Subsequently, the reliability and statistical validity of the scale were evaluated. Results: After content analysis, the results confirmed a four-dimensional structure with a Cronbach’s α value of 0.933 for the Provider Attitudes towards Planned Home Birth (PAPHB) scale as a whole, showing good internal consistency. Finally, a bivariate analysis was carried out identifying associations between variables and midwives’ attitudes towards home birth. Positive attitudes towards homebirth were strongly influenced by previous clinical experience and exposure to home birth during midwives’ academic education. Conclusion: The 18-item scale is a reliable and valid tool to quantify attitudes towards planned home births in Portugal as the results obtained in the study showed very good internal consistency.
