The influence of maternal singing on well-being, postpartum depression and bonding - a randomised, controlled trial

Postpartum depression is fairly common in new mothers and moreover associated with impaired bonding and poor maternal well-being. The aim of the present study was to investigate the impact of a mother-infant singing intervention within the first three months after birth on maternal well-being, depressive symptoms and bonding.

120 women who were recruited at the maternity ward at the University Clinic in Düsseldorf took part in this prospective, randomised-controlled study. Beside the baseline measurement 1-3 days after childbirth, depressive symptoms, maternal well-being and mother-infant bonding were evaluated with questionnaires before (two weeks after birth) and after (twelve weeks after birth) the intervention took place. The experimental group (n = 59) participated in several singing intervention sessions while the control group (n = 61) did not. In the intervention group, salivary cortisol as well as attachment and mood were assessed immediately before and after the singing sessions.

The participants of the intervention group showed a significant reduction of cortisol (p = .023) and an improvement of attachment and mood from start to end of the intervention session (all p ≤ .008). However, no prolonged effects were revealed beyond the intervention sessions as the two groups did not differ regarding the alterations of the primary outcomes postpartum depression (interaction effect p = .187) and postpartum bonding (interaction effect p = .188) in the 10-week period from two up to twelve weeks after childbirth (all p > .05). Additional analyses of singing habits at home in both groups, revealed that only in the singing group more frequent singing was associated with less anxiety and more well-being of the mother.

Singing towards the infant seems to have positive immediate effects on the well-being of new mothers (on subjective variables as well as physiological measurements). However, the intervention did not lead to more long lasting positive effects although several limitations should be considered.
