Adaptation and validation of the Spanish version of the Being a Mother scale.

Background: Becoming a mother is a very important process because of the impact it can have on women and their families. Currently, there is no validated questionnaire that evaluates the process of becoming a mother in the Spanish population. Moreover, no consistent results have been obtained to identify significant differences between primiparous and multiparous mothers. Aim: (1) Linguistic and metric validation of the Being a Mother scale (BaM-13) in the Spanish population, (2) analysis of possible differences between primiparous and multiparous mothers' experience of motherhood. Methods: Instrumental design. In 2016–2017, a sample of 579 mothers with children between 6 and 11 months of age completed the Spanish version of BaM-13. The instrument was translated using forward and back translation. Construct validity, internal consistency, and criterion validity were empirically analyzed. Results: Factorial analyses showed that the scale presented two adequate factors. Internal consistency of the global scale (α = 0.818, ω = 0.861), the Postnatal bonding factor (α = 0.773, ω = 0.784), and the Adult's experience factor (α = 0.710, ω = 0.721) was adequate. Significant associations were found with postpartum depression (r = 0.560), parental competence (r = − 0.584) and postnatal bonding (r = − 0.327). In terms of parity, primiparous mothers have greater difficulty in postnatal bonding, compared to multiparous mothers (p = 0.006). Conclusions: The Spanish version of the BaM-13 scale is valid for measuring mothers' experience of motherhood in a wide range of domains. The findings of the study show the importance of considering parity in the experience of becoming a mother, highlighting the approach to postnatal bonding in primiparous mothers. Additionally, we underline that it should not be assumed that multiparous mothers experience fewer difficulties in their motherhood process. [ABSTRACT FROM AUTHOR]
