O-16: Psychometric Properties of The Persian Version of Prenatal Attachment Inventory (PAI) in Iranian Pregnant Women

Background Prenatal attachment inventory (PAI) was developed by Muller in 1993, and has been used widely in many studies and translated into several languages. This study aimed to translate PAI into Persian, and assess the underlying structure of the PAI and the appropriateness of the one-factor solution proposed by Muller MaterialsAndMethods In this cross-sectional study, a total of 322 primigravidas in 27th to 34th gestational weeks referring to private and governmental prenatal clinic in Tehran, Iran, were recruited. The Persian versions of the PAI and a demographic questionnaire were administered to all participants, and the participants were re-tested 2 weeks after the initial testing. The psychometric properties of the PAI were investigated: construct validity using confirmatory factor analysis (CFA), internal consistency reliability using Cronbach’s alpha, and testretest reliability using Intra class correlation coefficient (ICC). Results Results of the CFA indicated that a single-factor model provides a good fit to the data, confirming an original model by its developer. The Cronbach’s alpha coefficient for PAI was 0.856 and the test–retest reliability with ICC was 0.784. Considering duration between marriage and pregnancy, women with low duration scored significantly higher than women with high on PAI (P=0.043). Conclusion The Persian version of PAI showed that one factor structure is adequate, and can be used for measuring psychological affectionate attachment between Iranian mothers and their fetus.
