[The development of maternal-fetal attachment during pregnancy]

This study is to examine the degree to which women engage in attachment behaviors toward their unborn children. Cranley's Maternal-Fetal Attachment Scale (MFAS) was modified to Japanese version (MFAS-J2), which consists of 20 items with .87 reliability. MFAS-J2 was administered to both normal and high-risk pregnant women (n = 275) during gestation. All subjects were restricted to women who were having their first child, and they were between 5 and 40 weeks gestation at the time they completed the instrument. Demographic data were also gathered.

(1) Maternal-fatal attachment increased significantly from 5 to 40 weeks of gestation. Especially feeling fetal movement had positive effect on maternal-fetal attachment. (2) Women who reported negative perception or ambivalent feeling about their pregnancy showed low attachment score. And women whose husband reported negative feeling about their pregnancy responded lower in the scale. (3) Some negative relationships were observed between maternal-fetal attachment score and the histories of abortion and sterility. (4) Maternal-fetal attachment showed no significant correlations to factors of threatened abortion, premature labor, and IUGR. (5) Maternal-fetal attachment showed negative correlations to State-Trait anxiety during early pregnancies.
