The present study sought to document an example of how maternal and infant vulnerabilities
interact in contributing to the quality of early attachment relationships. Maternal depressive
symptoms, neonatal health characteristics, and infant–mother attachment were assessed for
42 preterm, low birth weight infants and 42 full-term infants at 12 months postterm. Results
indicated that preterm birth moderated the relation between maternal depressive symptoms and
quality of infant–mother attachment, even controlling for level of neonatal health
complications. Preterm infants with more symptomatic mothers were most likely to be classified
as insecurely attached to their mothers, whereas no direct relation between subclinical depressive
symptoms and attachment was found for full-term infants.
