Objective
To compare the trajectories and determine the predictors of maternal distress, defined as a continuous spectrum of symptomatology and elevated symptomatology, of depression, anxiety and perinatal-specific post-traumatic stress (PPTS), in mothers of very low birth weight (VLBW) infants throughout the neonatal intensive care unit (NICU) hospitalization.
Method
69 mothers completed psychological questionnaires within the first month of their infant’s NICU hospitalization and again two weeks prior to NICU discharge. Multiple regression models determined maternal psychological, reproductive, sociodemographic, and infant medical predictors of maternal distress.
Results
PPTS remained stable throughout the NICU hospitalization while other aspects of distress declined. Previous psychological history and infant medical variables predicted higher PPTS but no other aspects of distress. Reproductive variables predicted anxiety and PPTS; history of fetal loss initially predicted lower PPTS, but throughout hospitalization primipara status emerged as a predictor of higher anxiety and PPTS. Sociodemographic variables predicated initial, but not later, depressive distress.
Conclusion
Psychological screening is important in the NICU. The PPTS profile suggests it may require distinct treatment. Primiparas should be targeted for intervention.
