Abstract
PURPOSE: To determine the relationship of prenatal attachment and other selected perinatal contextual variables (method of delivery, maternal self-reported health, depression, infant birthweight, need for neonatal intensive care unit [NICU] admission) to postnatal attachment in mothers of twins. SUBJECTS: Two hundred fourteen women were initially recruited from a national mothers of twins support group for a study of maternal prenatal attachment. Of the 168 women who agreed to be contacted after delivery, 142 returned completed questionnaires (82.7% response rate), with 139 study-eligible women included in the analysis for this report. STUDY DESIGN: Correlational design with longitudinal follow-up at 1 month after expected delivery date. METHODS: Self-administered, mailed questionnaires completed by women with twin gestations prenatally and postnatally 1 month after their expected delivery dates. Descriptive analysis, correlations, and regression equations were performed. MAIN OUTCOME MEASURES: The Maternal Attachment Inventory. PRINCIPLE RESULTS: A modest correlation was found between prenatal and postnatal attachment ( r = 0.38, P < 0.001). Prenatal attachment and postpartum depression explained 26.1% of the variance in postnatal attachment ( F = 5.06, P < 0.001). Depression, method of delivery, and need for admission to the NICU had moderator effects on the relationship between prenatal attachment and postnatal attachment. The addition of these interaction terms nominally increased the adjusted R 2 to explain 27.9% to 29.6% of the variance in postnatal attachment. CONCLUSIONS: Although the study findings support a modest relationship between prenatal and postnatal attachment in mothers of twins, maternal depression was also significant in explaining postnatal attachment. Postpartum depression, having a cesarean delivery, and the experience of a NICU admission for 1 or both twins further influenced the relationship between prenatal attachment and postnatal attachment. When fostering attachment in mothers of twins, nurses should assess for symptoms of depression and pay particular attention to those women who have an infant requiring a NICU admission.
