The purpose of this study is to verify the validity and reliability of Condon's Maternal Antenatal Attachment Scale(MAAS) to measure maternal fetal attachment. The subjects of this study were 854 pregnant women who participated in the education of pregnant women in Seoul and Gyeonggi. The collected data were analyzed using statistical programs SPSS 23.0 and M-plus 7, evaluating factor structure, reliability, and validity. The exploratory factor analysis of 401 pregnant women revealed that 15 items were generated from a two factor structure (attachment quality, attachment intensity). The final 15 items were found to be in good correlations with each other, with the reliability coefficient of .82. The results of the confirmatory factor analysis of 453 pregnant women proved that the two factor model and the item composition were valid. Validity analysis showed significant correlations among adult attachment, prenatal anxiety, prenatal depression, MFAS, and MAAS. Criterion validity and concurrent validity were thus verified. Based on the results of this study, we discussed the application of the MAAS scale and implications for future research.
