Mothers' interoceptive sensibility mediates affective interaction between mother and infant.

ABSTRACT: 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.

Project description:BackgroundInteroception refers to the sensing, interpretation, integration, and regulation of signals about the body's internal physiological state. Interoceptive sensibility is the subjective evaluation of interoceptive experience, as assessed by self-report measures, and is abnormal in numerous neuropsychiatric disorders. Research examining interoceptive sensibility in individuals with chronic tic disorders (CTDs), however, has yielded conflicting results, likely due to methodologic differences between studies and small sample sizes.ObjectiveWe sought to compare interoceptive sensibility between adults with CTD and healthy controls, adjusting for co-occurring psychiatric symptoms, and to examine the relationship of interoceptive sensibility with other CTD clinical features, in particular, premonitory urge.MethodsWe recruited adults with CTDs and sex- and age-matched healthy controls to complete the Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2), as well as a battery of measures assessing psychiatric symptoms prevalent in CTD populations. CTD participants additionally completed scales quantifying tic severity, premonitory urge severity, and health-related quality of life. We conducted between-group contrasts (Wilcoxon rank-sum test) for each MAIA-2 subscale, analyzed the effect of psychiatric symptoms on identified between-group differences (multivariable linear regression), and examined within-group relationships between MAIA-2 subscales and other clinical measures (Spearman rank correlations, multivariable linear regression).ResultsBetween adults with CTD (n = 48) and healthy controls (n = 48), MAIA-2 Noticing and Not-Worrying subscale scores significantly differed. After adjusting for covariates, lower MAIA-2 Not-Worrying subscale scores were significantly associated with female sex (β = 0.42, p < 0.05) and greater severity of obsessive-compulsive symptoms (β = -0.028, p < 0.01), but not with CTD diagnosis. After adjusting for severity of tics and obsessive-compulsive symptoms, a composite of MAIA-2 Noticing, Attention Regulation, Emotional Awareness, Self-Regulation, Body Listening, and Trusting subscales (β = 2.52, p < 0.01) was significantly associated with premonitory urge.ConclusionStudy results revealed three novel findings: adults with CTD experience increased anxiety-associated somatization and increased general body awareness relative to healthy controls; anxiety-associated somatization is more closely associated with sex and obsessive-compulsive symptoms than with CTD diagnosis; and increased general body awareness is associated with greater severity of premonitory urges.
