Note: Means and SDs are reported for normally distributed data; Medians and Interquartile Ranges (IQR) are reported for nonnormally distributed data. Maternal negativity was initially skewed, so a reciprocal transformation (1/negativity) was completed to normalize data, and then reverse coded. NICU=Neonatal Intensive Care Unit. BDI-II = Beck Depression Inventory, 2nd Edition; EPDS = Edinburgh Postnatal Depression Scale; PDA = Patent Ductus Arteriosus.
