title: Stress levels and depressive symptoms in NICU mothers in the early postpartum period.
abstract: OBJECTIVE
  This study examined whether particular maternal and infant factors can identify mothers at risk for increased stress upon admission to the neonatal intensive care unit (NICU).
  
  
  METHODS
  Eighty-five mothers of preterm infants (25-34 weeks gestation) were assessed using the Parental Stressor Scale (PSS:NICU) and the Edinburgh Postnatal Depression Scale (EPDS) within 3.24 ± 1.58 d postpartum. Hierarchical linear regression models were used to determine the extent to which maternal stress is influenced by individual factors.
  
  
  RESULTS
  Fifty-two percent of mothers experienced increased stress (PSS:NICU score ≥3) and 38% had significant depressive symptoms (EPDS score ≥10). Stress related to alterations in parental role was the most significant source of stress among NICU mothers. Distance from the hospital and married marital status were significant predictors for stress related to alterations in parental role (p = 0.003) and NICU sights and sounds (p = 0.01), respectively. Higher stress levels were associated with higher depressive scores (p = 0.001). Maternal mental health factors, demographic factors, pregnancy factors and infant characteristics were not associated with increased stress.
  
  
  CONCLUSIONS
  Elevated stress levels and depressive symptoms are already present in mothers of preterm infants upon NICU admission. Being married or living long distance from the hospital is associated with higher stress. Future work is needed to develop effective interventions for alleviating stress in NICU mothers and preventing its potential development into postnatal depression.
