Interoceptive sensibility, which denotes the self-perceived sensitivity to inner-body sensations, has been associated with the emotional experiences and inferences of others' emotional states. Focusing on the role of interoceptive sensibility in the emotional states and psychological well-being of mothers during caregiving, this study explores how physiological arousal and interoceptive sensibility mediate the association between mother-infant interaction and maternal well-being using an experience sampling method. Infant-directed-singing (IDS) with social touch was used to facilitate mother-infant interaction. Pairs of 2-8-month-old infants and their mothers participated. Mothers in an IDS group (N = 25) and a no-IDS group (N = 26) recorded their and the infant's daily feelings and physiological states using a smartphone application for one month. All participants, including the control group (N = 78) who neither performed IDS nor used the application, answered the Multidimensional Assessment of Interoceptive Awareness questionnaire before and after the recording period. Results indicated that IDS improved mother-infant interactions and positive feelings, enhancing maternal physiological arousal. Increased interoceptive sensibility enhanced infants' positive feelings in the IDS group, whereas in the no-IDS group, it weakened mother's positive feelings, suggesting that maternal interoceptive sensibility mediated the effects of IDS on mother and infant well-being.
内感受敏感性表示对内在身体感觉的自我感知敏感性，与他人情绪状态的情感体验和推断有关。本研究关注内感受敏感性在照顾期间母亲的情绪状态和心理健康中的作用，探讨了生理唤醒和内感受敏感性如何通过体验抽样法调节母婴互动与母亲幸福感之间的关系。使用带有社会触摸的婴儿导向唱歌（IDS）来促进母婴互动。将 2-8 个月大的婴儿及其母亲配对，参与研究。实验组（n=25）和对照组（n=26）的母亲使用智能手机应用程序记录一个月内自己和婴儿的日常感受和生理状态。所有参与者，包括既不进行 IDS 也不使用应用程序的对照组（n=78），在记录期前后均回答多维内感受意识评估问卷。结果表明，IDS 改善了母婴互动和积极感受，增强了母亲的生理唤醒。内感受敏感性的增加增强了 IDS 组中婴儿的积极感受，而在对照组中，它削弱了母亲的积极感受，这表明母亲的内感受敏感性介导了 IDS 对母婴幸福感的影响。
