Maternal depressive symptoms and affective responses to infant crying and laughing

Depressive symptoms are common in the postpartum period and can affect mother-infant interaction. To better understand the role of depressive symptoms in the mother-infant interchange, this study examined whether maternal depressive symptoms are associated with self-reported, physiological, and facial expressive responses to infant crying and laughing sounds. A nonclinical sample was used, consisting of 101 mothers (Age M = 30.88 years, 33% scored 7 or higher on the Edinburgh Postnatal Depression Scale) with a young child. Mothers were exposed to standard infant crying and laughing sounds. Affect, perception of crying and laughing, intended caregiving responses, skin conductance level reactivity, and facial expressive responses to infant crying and laughing were measured. Higher levels of depressive symptoms were associated with more self-reported negative affect in general and a more negative perception of infant crying. Depressive symptoms were not associated with intended caregiving responses and physiological responses to infant crying. Infant laughing increased self-reported positive affect and happy facial expressions in mothers with all levels of depressive symptoms. Higher levels of depressive symptoms were associated with higher sad facial expressivity in general. Depressive symptoms were not related to positive perception of infant laughing, intended caregiving responses, and physiological responses to infant laughing. The findings suggest that mothers who score high on depressive symptoms send subtle facial cues showing sadness, which may overshadow happy facial expressions during infant laughing and may affect mother-infant interaction.
