Increased maternal fetal attachment (MFA) is associated to improved health practices. A tool to measure MFA within an Arab cultural context was developed to help health care providers identify and help women with low MFA. Muller's 21-item Prenatal Attachment Inventory (PAI) was translated from English into Arabic and tested on 250 pregnant Arab women in Riyadh, Saudi Arabia to measure its psychometric properties and appropriateness within an Arab cultural context. A cross-sectional quantitative study was conducted in two phases. First, the tool was translated using the Universal Translation Approach and assessed for content validity. In this phase there were four new items added to the original tool and their validity was tested in the second phase. In the second phase, the tool was tested on the study population, descriptive statistics were developed, association tests were used to explore associations between demographic variables and MFA, factor analysis was conducted and reliability was assessed using Cronbach's alpha coefficient. Associations between MFA and maternal variables were found such as downloading an application to follow the baby's growth, planning to breastfeed the baby and parity. The Arabic tool could serve Arab-speaking countries and help researchers explore new associations between MFA and the social determinants of health for Arab mothers and babies. Key words: Maternal fetal attachment, maternal antenatal attachment, psychometrics, attachment, mother-fetus attachment, Arabic maternal fetal attachment, and Arab maternal fetal attachment. ii Acknowledgements This work was supported by Qatar Research Leadership Program (QRLP) from the Qatar Foundation in Doha, Qatar.
