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.

母亲的抑郁症状和对婴儿哭笑的情感反应。

抑郁症状在产后很常见，会影响母婴互动。为了更好地了解抑郁症状在母婴交流中的作用，本研究检查了母亲的抑郁症状是否与婴儿哭声和笑声的自我报告、生理和面部表情反应相关。使用非临床样本，其中包括 101 名带着幼儿的母亲（年龄 M = 30.88 岁，33% 的爱丁堡产后抑郁量表得分为 7 或更高）。母亲们接触到标准的婴儿哭声和笑声。测量了情感、哭和笑的感知、预期的护理反应、皮肤电导水平反应性以及对婴儿哭和笑的面部表情反应。较高水平的抑郁症状通常与更多的自我报告的负面情绪以及对婴儿哭泣的负面感知有关。抑郁症状与预期的照顾反应和对婴儿哭泣的生理反应无关。婴儿的笑声增加了患有各种抑郁症状的母亲自我报告的积极情绪和快乐的面部表情。一般来说，较高水平的抑郁症状与较高的悲伤面部表情有关。抑郁症状与婴儿笑声的积极感知、有意的护理反应以及对婴儿笑声的生理反应无关。研究结果表明，抑郁症状得分高的母亲会发出微妙的悲伤表情，这可能会掩盖婴儿大笑时快乐的面部表情，并可能影响母婴互动。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
