Maternal depression, anxiety, stress, and maternal-infant attachment in the neonatal intensive care unit

The objectives of this study were to identify maternal psychological responses to infants' neonatal intensive care unit (NICU) admission, understand the relationship between psychological symptoms and maternal-infant attachment, and evaluate change in psychological symptoms over time.

Accumulating evidence suggests that infants' admission to a NICU may adversely impact maternal psychiatric functioning. NICU mothers typically experience high levels of depressive, anxiety, and stress symptoms.

Mothers (N = 127) recruited from their infants' NICU bedside at three hospitals in the Philadelphia area completed self-report measures of depression, anxiety, stress, and maternal-infant attachment during the NICU admission and then 2-4 months later. A series of bivariate correlations, paired samples t-tests, and linear regression analyses were used to evaluate the primary study aims.

NICU mothers reported elevated rates of depressive, anxiety, and stress symptoms. Maternal-infant attachment was negatively associated with anxiety and stress symptoms. Both depressive and anxiety symptoms were higher during NICU admission compared to 2-4 months later, and depressive symptoms during NICU admission predicted depressive symptoms 2-4 months later.

This study demonstrates that NICU admission may heighten maternal risk for psychiatric symptoms, and maternal-infant attachment in the NICU may be an important correlate of maternal anxiety and stress symptoms.
