A prospective study of 143 "low risk" pregnant women expecting their first baby was conducted in Newcastle, Australia. The study was designed to examine the contribution of a woman's perception of her own childhood experiences, her trait anxiety level, socioeconomic status, and social support network to difficulties in her relationship with her baby during the baby's first year. The women were initially interviewed during pregnancy and followed up 3 and 12 months postpartum. Follow-up measures included the Dimensions of Perinatal Adjustment, the Neonatal Perception Inventory, the Ainsworth Strange Situation, and information from hospital records, family doctors, and baby health centre sisters. Women who perceived their social network as less supportive during pregnancy were likely to see their one-year-old babies (p < .05) as more difficult. The other antenatal measures were not significantly predictive of outcome. © 1991.
