Symptoms of Acute Stress Disorder in Mothers of Premature Infants

PURPOSE: To determine whether significant symptoms of acute stress disorder (ASD) are present in mothers of premature infants in the neonatal intensive care unit (NICU). SUBJECTS: Forty mothers of premature infants born less than 33 weeks and admitted into NICU. DESIGN: Prospective, cohort, within-subjects. METHODS: Mothers completed the Stanford Acute Stress Reaction Questionnaire, Edinburgh Postnatal Depression Scale, and the Acute Stress Disorder Interview to explore the number and severity of stress-related symptoms at 2 separate time periods, 7 to 10 days after birth, and 1 month after birth. RESULTS: Twenty-eight percent of the mothers met diagnostic criteria of ASD at 7 to 10 days after birth, and at 1 month after birth ASD symptoms persisted. The majority of the mothers described premature birth as a traumatic stressor. The most commonly met criteria were dissociation and anxiety. Significant symptoms of depression were found in 43% of mothers and persisted 1 month after birth. Rates of depression and moderate to severe symptoms of ASD were significantly related in mothers at 1 week and at 1 month after birth. CONCLUSIONS: The premature birth experience is traumatic for mothers and may lead to various emotional responses including stress-related symptoms such as depression and/or ASD. Mothers with significant symptoms of depression and those with symptoms of stress seem to be more at risk for developing symptoms of ASD.
