Antenatal and postnatal depressive symptoms: Association with quality of mother-infant interaction

Antenatal and postnatal depression are independently associated with an increased risk of adverse infant development. A key linking mechanism is the quality of mother-infant interaction.

This study assesses the association between postnatal depressive symptoms (PDS) and their severity, with the quality of mother-infant interaction and compare the quality of mother-infant interaction and severity of the symptoms depending on the presence or absence of antenatal depressive symptoms (ADS).

observational study in 177 psychosocial risk mother-infant dyads from Chile (infant aged 2-12 months).

Mothers with PDS had lower maternal sensitivity and a more intrusive/controlling style than mothers without PDS, although the severity of the symptoms was not associated with lower maternal sensitivity. Maternal sensitivity did not differ in the postnatal depressed mothers depending on the presence of ADS, although the mothers differed in interaction style and the severity of symptoms. Mothers with ADS and PDS presented with a predominant intrusive/controlling interaction style and more severe depressive symptoms, whereas those with only PDS presented with a predominant nonresponsive/passive interaction style and reduced severity of symptoms.

The results corroborate the need to offer treatment and dyadic interventions to antenatal and postnatal depressive mothers and postulate that the presence of antenatal depressive symptoms may influence the subsequent mother-infant interaction style and greater severity of symptoms.
