Abstract. This study sought to identify factors influencing maternal-fetal at-tachment in high-risk pregnancy in Korea. Data were collected between March 3 and 30, 2015 via structured questionnaires completed by 118 pregnant women visiting an obstetric clinic for prenatal tests or referred to university hospitals in three metropolitan areas for pregnancy maintenance. Data were analyzed, using IBM SPSS version 22,via descriptive statistics, tests, ANOVA, Pearson's corre-lation coefficients, and stepwise multiple regression. Childbirth experience, an-tepartum care, and planned pregnancy differed significantly. Anxiety and ma-ternal-fetal attachment were negatively correlated, whiledyadic adjustment and maternal-fetal attachment were positively correlated. Anxiety, multiparity, pre-natal care, and dyadic adjustment influenced maternal-fetal attachment in high-risk pregnancy. These variables explained 20.5% of the variance in maternal-fetal attachment. The results indicate a need for the development and applica-tion of nursing interventions to decrease anxiety in high-risk pregnancy and im-prove maternal-fetal attachment via conjugal harmony.
