Treating infant sleep disturbance: does maternal mood impact upon effectiveness?

ABSTRACT

AIM: To explore whether mild-to-moderate maternal depression affects the effectiveness of a behavioural approach to treating infant sleep disturbance (ISD). METHODS: The health records of 90 mothers attending an inpatient parenting service for management of their 5-12-month-old infant's sleep difficulties were examined. These records contained detailed, nurse-completed, 24-hour behaviour charts of infant sleeping and crying. Participants were allocated to the depression group based on Edinburgh Depression Scale score and/or review of mental health assessment notes. RESULTS: There were no differences between infants of mothers with (n= 39) or without (n= 51) depression on either (i) the severity of their initial sleeping difficulty, or (ii) their response to behavioural treatment. Both groups showed significant improvements over the 5-day stay on all sleep variables observed, including number of night wakings, time to fall asleep, time spent crying at night and total time slept at night. CONCLUSIONS: Mild-to-moderate maternal depression does not appear to attenuate ISD behavioural treatment outcomes. Given ISD treatment has been shown to improve maternal mood, the results of this study argue against recommendations initially to address maternal mood in isolation when managing ISD.
