How do maternal emotional regulation difficulties modulate the mother-infant behavioral synchrony?

How and Why People Synchronize: An Integrated Perspective

Academic AbstractInterpersonal synchrony, the alignment of behavior and/or physiology during interactions, is a pervasive phenomenon observed in diverse social contexts. Here we synthesize across contexts and behaviors to classify the different forms and functions of synchrony. We provide a concise framework for classifying the manifold forms of synchrony along six dimensions: periodicity, discreteness, spatial similarity, directionality, leader-follower dynamics, and observability. We also distill the various proposed functions of interpersonal synchrony into four interconnected functions: reducing complexity and improving understanding, accomplishing joint tasks, strengthening social connection, and influencing partners' behavior. These functions derive from first principles, emerge from each other, and are accomplished by some forms of synchrony more than others. Effective synchrony flexibly adapts to social goals and more synchrony is not always better. Our synthesis offers a shared framework and language for the field, allowing for better cross-context and cross-behavior comparisons, generating new hypotheses, and highlighting future research directions.

Emotion Regulation, Parenting, and Psychopathology: A Systematic Review

The presence of a parental mental disorder can lead to adverse outcomes for children. Difficulties in emotion regulation are observed across a range of mental health problems and may play a crucial role in this context. Following PRISMA guidelines, we systematically searched Medline, PsycINFO, Embase, and Web of Science for studies examining the association between emotion regulation in parents with psychopathology at a clinical or subclinical level and their parenting. The protocol was registered with the PROSPERO international prospective register of systematic reviews (CRD42021224954; January 2021). A total of 23 studies were included in the qualitative synthesis. Emotion regulation was predominantly assessed using self-report on the general ability (e.g., Difficulties in Emotion Regulation Scale). The assessment of parenting encompassed a broad range of aspects and operationalizations. Across psychopathology in parents, several aspects of difficulties in emotion regulation were associated with unfavorable emotion socialization, more negative parenting, and partially with less positive parenting. Slightly different effects were observed for posttraumatic stress disorder and anxiety disorders. For parents with depressive disorders, specific emotion regulation strategies (suppression, reappraisal) seem to buffer against negative parenting. Since the majority of studies refer only to mothers, generalization to fathers is limited. Furthermore, conclusions are limited due to study heterogeneity and lack of prospective studies. Nevertheless, findings suggest that interventions should target the improvement of emotion regulation in parents with psychopathology.

Maternal anxiety symptoms associated with increased behavioral synchrony in the early postnatal period

The presence of perinatal mood and anxiety disorders has typically been associated with decreases in the quality of mother-infant interactions. However, maternal anxiety symptoms during the postpartum period have been less studied than other mental health disorders like depression. In the current study, we examined associations among symptoms of maternal anxiety, maternal perceived stress, and mother-infant behavioral synchrony in the early postnatal period. Eighty-one mother-infant dyads participated in this study when the infants were 3 months old. Surveys were given to obtain demographic information and current maternal mental health symptoms, and dyads completed a 5-min free-play task to measure behavioral synchrony. Results indicated that maternal anxiety symptoms were positively associated with behavioral synchrony, but only for mothers reporting moderate levels of perceived stress. These findings highlight the differential impact of maternal postpartum mental health on behavioral synchrony and suggest that higher maternal anxiety symptoms during the postnatal period may play an adaptive role in fostering more dynamic mother-infant interactions.
