Interactive synchrony and infantsâ vagal tone as an index of emotion regulation: associations within each mother- and father-infant dyad and across dyads
IntroductionStudies have shown that infantsâ emotion regulation capacities are closely linked to the quality of parent-infant interactions. However, these links have been mostly studied in mother-infant dyads and less is known about how the quality of father-infant interactions contributes to the development of emotion regulation during infancy. In this study, we aimed to investigate the links between interactive synchrony (i.e., an index of the quality of parent-infant coordination of interactive behaviors) and infantsâ vagal tone (i.e., a physiological index of emotion regulation). To understand the respective contributions of both parents, as well as the interrelations between the functioning of both dyads within a family, we observed mothers and fathers from 84 families interacting with their infants.MethodsSynchrony was assessed by using the CARE-Index; infantsâ vagal tone was derived from the analysis of infantsâ electrocardiograms recorded during the interactions. Moreover, to take the playâs order into account, we counterbalanced the procedure, so that approximately half of the mothers played first. We specified a first structural equation modeling (SEM) model to investigate the associations between interactive synchrony and the infantsâ root mean square of successive differences (RMSSD), an index of vagal regulation, in the two successive parts of the play. We conducted a multigroup analysis in a second SEM model to investigate the associations of the first SEM model in two groups based on the order of interaction.ResultsThe results of the SEM models showed that greater synchrony was related to greater infant RMSSD within mother-infant dyads and across one dyad to the other dyad in the full sample and in the group of fathers who interacted first with the infants. The associations between synchrony and infant vagal tone within father-infant dyads never appeared to be significant, nor did any associations within each dyad and across dyads when mothers interacted first.DiscussionThis study highlights that the links between interactions and infantsâ vagal tone are sensitive to family membersâ interdependencies and some conditions (the order of interaction)
Parental sensitivity, family alliance and infants' vagal tone: Influences of early family interactions on physiological emotion regulation
In this study, we investigated the influence of parental sensitivity and family alliance on infantsâ vagal tone, considered as a physiological indicator of emotion regulation. Studies on motherâinfant interactions have shown that vagal tone can be influenced by the quality of the interaction, such as interacting with a sensitive mother. To date, no study has investigated the influence of paternal sensitivity or family alliance on infantsâ vagal tone. We hypothesized that maternal sensitivity, paternal sensitivity, and family alliance would be associated with infantsâ vagal tone during dyadic and triadic interactions. We also explored if family alliance would act as a moderator on the association between parental sensitivity and vagal tone and if the sensitivity of both parents would act as a moderator on the association between family alliance and vagal tone. This study took place in Switzerland and included 82 families with their 3â4-month-old infants. Results showed that maternal sensitivity and family alliance were associated with infantsâ vagal tone, but paternal sensitivity was not. We found no significant moderation effect. However, result tendencies suggested that the contribution of paternal sensitivity to infantsâ emotion regulation could be influenced by family alliance, whereas maternal sensitivity and family alliance have a unique contribution
Ătude des processus de rĂ©gulation physiologique de l'enfant dans les interactions familiales
Contexte théorique et objectif général :
Le dĂ©veloppement de la rĂ©gulation Ă©motionnelle a Ă©tĂ© identifiĂ© comme un processus clĂ© permettant dâexpliquer les associations entre les relations parent-enfant et le fonctionnement psychologique de lâenfant. Les recherches sur les interactions mĂšre-enfant ont notamment montrĂ© que la qualitĂ© des interactions Ă©tait associĂ©e Ă au dĂ©veloppement des capacitĂ©s de rĂ©gulation Ă©motionnelle des enfants et que cette influence Ă©tait observable Ă un niveau physiologique. Bien que la recherche montre une influence des interactions pĂšre-enfant et mĂšre-pĂšre-enfant sur le fonctionnement psychologique des enfants, jusquâĂ aujourdâhui, lâĂ©tude des processus physiologiques nâa Ă©tĂ© que trĂšs peu investiguĂ©e dans ces contextes dâinteraction. Ce travail de thĂšse vise Ă combler ce manque.
MĂ©thode :
119 familles ont Ă©tĂ© recrutĂ©es durant la grossesse. Ă 3 mois postpartum, les familles Ă©taient rencontrĂ©es dans un laboratoire. Il leur Ă©tait alors demandĂ© dâinteragir selon le paradigme suivant : un parent joue avec lâenfant pendant que lâautre est Ă lâextĂ©rieur de la piĂšce, ils Ă©changent ensuite les rĂŽles, ils interagissent ensuite tous les trois, et finalement lesparents ont une conversation ensemble Ă cĂŽtĂ© de lâenfant. Ces interactions ont Ă©tĂ© filmĂ©es et plusieurs codages indicatifs de la qualitĂ© des interactions ont Ă©tĂ© effectuĂ©s (sensibilitĂ© parentale, comportements parentaux intrusifs/dĂ©sengagĂ©s, alliance familiale). Un ECG a Ă©tĂ© enregistrĂ© chez lâenfant durant le paradigme afin dâobtenir une mesure du tonus vagal, un indicateur des capacitĂ©s de rĂ©gulation Ă©motionnelle. Les parents remplissaient ensuite un jeu de questionnaires dans les semaines aprĂšs le rendez-vous, ainsi quâun second jeu de questionnaires aux 18 mois de lâenfant.
RĂ©sultats :
De maniĂšre gĂ©nĂ©rale, les rĂ©sultats montrent une influence de la qualitĂ© des interactions mĂšre-enfant et mĂšre-pĂšre-enfant sur les mesures de rĂ©gulation physiologique de lâenfant. Une sensibilitĂ© maternelle Ă©levĂ©e est associĂ©e Ă un tonus vagal plus Ă©levĂ© chez
lâenfant durant les interactions mĂšre-enfant, confirmant les prĂ©cĂ©dents rĂ©sultats de la littĂ©rature scientifique. Un score dâalliance familiale Ă©levĂ© est associĂ© Ă un tonus vagal plus Ă©levĂ© chez lâenfant durant les interactions mĂšre-pĂšre-enfant et cette association est en partie expliquĂ©e par la rĂ©ponse comportementale des enfants aux comportements parentaux intrusifs/dĂ©sengagĂ©s prĂ©sents dans lâinteraction. Les rĂ©sultats ne montrent pas dâinfluence de la sensibilitĂ© paternelle sur le tonus vagal de lâenfant durant lâinteraction pĂšre-enfant. Les rĂ©sultats suggĂšrent Ă©galement que le fait de passer plus de temps avec ses deux parents pourrait favoriser le dĂ©veloppement de la rĂ©gulation Ă©motionnelle physiologique.
Conclusion :
Ce travail souligne lâimportance de considĂ©rer les interactions familiales au- delĂ de la dyade mĂšre-enfant dans la comprĂ©hension du dĂ©veloppement des capacitĂ©s de rĂ©gulation Ă©motionnelle de lâenfant. Les rĂ©sultats encouragent Ă©galement Ă dĂ©velopper une meilleure connaissance de lâinfluence des interactions pĂšre-enfant sur le dĂ©veloppement delâenfant.</p
Lâinfluence de lâamorçage implicite du concept de capacitĂ© sur lâeffort mesurĂ© par la rĂ©activitĂ© cardiovasculaire
Cette Ă©tude avait pour but dâinvestiguer lâimpact de lâamorçage du concept de capacitĂ© sur la mobilisation de lâeffort. Lâeffort Ă©tait mesurĂ© par la rĂ©activitĂ© cardiovasculaire (pĂ©riode de prĂ©-Ă©jection et pression systolique) lors dâune tĂąche cognitive facile, durant laquelle des mots relatifs Ă la capacitĂ©, Ă lâincapacitĂ© ou neutres Ă©taient prĂ©sentĂ©s rapidement de façon implicite. Nous prĂ©disions un effet linĂ©aire de lâamorçage du concept de capacitĂ© sur lâeffort : moins dâeffort dans la condition capacitĂ©, plus dâeffort dans la condition neutre et encore plus dâeffort dans la condition incapacitĂ©. LâhypothĂšse nâa pas Ă©tĂ© confirmĂ©e. Nous nâavons pas non plus trouvĂ© dâeffet sur la performance. En revanche, lâamorçage a influencĂ© la capacitĂ© perçue des participants dans le sens attendu et les participants nâont pas rapportĂ© avoir vu les mots prĂ©sentĂ©s. Ces rĂ©sultats montrent quâil est possible de manipuler le sentiment de capacitĂ© de maniĂšre implicite. Les rĂ©sultats des mesures cardiovasculaires de lâeffort sont discutĂ©s en considĂ©rant le niveau de difficultĂ© de la tĂąche

Swiss cohort on Traumatic Childbirth and Health (SwiTCH): protocol for a prospective, population-based cohort study on parentsâ mental health from pregnancy to one year postpartum
Introduction Approximately 4%â5% of mothers develop childbirth-related post-traumatic stress disorder (CB-PTSD) and approximately 12.3% of mothers develop some CB-PTSD symptoms (CB-PTSS). To date, there is a dearth of studies on fathers and other coparents. Parental CB-PTSD and CB-PTSS may have a negative impact not only on the parents but also on the infant. Understanding risk and protective factors of CB-PTSD for both parents and its consequences on the family is key to detecting or anticipating it, to developing interventions aimed at reducing its detrimental effects and to supporting parents.Methods and analysis This study protocol describes an observational, population-based study, consisting of a longitudinal prospective cohort with online surveys at four time points. The population of interest consist of women, in the third trimester of pregnancy or at 6â12 weeks postpartum, and their partner/coparent, who will give birth or gave birth in the French-speaking part of Switzerland. The target sample size is 300â500âwomen and a proportional number of partners. The primary outcome of this study is the prevalence of CB-PTSD and CB-PTSS. The secondary outcomes focus on: (1) the impact of CB-PTSD and CB-PTSS on the marital and coparental relationships, the bonding with the infant, parental burnout and healthcare seeking behaviours, (2) the role of the childbirth experience in the development of CB-PTSD and CB-PTSS and (3) the social and economic determinants of CB-PTSD and CB-PTSS.Ethics and dissemination Ethical approval was granted by the human research ethics committee of the Canton de Vaud (study number 2022-00284). All study participants signed an informed consent form. Dissemination of results will occur via national and international conferences, in peer-reviewed journals, public conferences and social media.Trial registration number NCT05865704
Parental sensitivity, family alliance and infantsâ vagal tone ::influences of early family interactions on physiological emotion regulation
In this study, we investigated the influence of parental sensitivity and family alliance on infantsâ vagal tone, considered as a physiological indicator of emotion regulation. Studies on motherâinfant interactions have shown that vagal tone can be influenced by the quality of the interaction, such as interacting with a sensitive mother.

The interplay between maternal and paternal senses of efficacy moderates the link between perinatal parental stress and family alliance at 3 months
Objective: Both parents may report high levels of stress during the perinatal period with possible negative consequences for parental well-being and child development. Parental sense of efficacy moderates the effect of stress. To date, no studies have assessed links between parental stress and mother-father-infant interactions in terms of family alliance and the extent to which each parentâs sense of efficacy moderates these links. Design: In this study, 65 dual-parent families answered a questionnaire about parental stress between 36 and 38âweeks of pregnancy and at 3âmonths after birth. Families were also observed while playing with their 3-month-old infant in the Lausanne Trilogue Play, and they completed a questionnaire about parental efficacy. Results: Structural equation modeling analyses showed that higher maternal or paternal postnatal stress has a direct link with higher family alliance and the links between stress and family alliance are moderated by complex interaction effects between maternal and paternal senses of efficacy. Conclusions: This study shows the necessity of considering the interaction between the senses of self-efficacy of both parents as moderators of parenting stress
Father-infant synchrony and infant vagal tone as an index of emotion regulation ::father-infant shared times in Switzerland as moderators
Research has shown that the quality of mother-infant interactions, as measured by mother-infant synchrony, is associated with infantsâ vagal tone, a physiological indicator of emotion regulation. However, little is known about the association between the infantâs vagal tone and the quality of father-infant interactions. Existing literature suggests that the greater quantity of time a father spends with the infant, either alone (dyadic time) or with others (social time) may strengthen this association. In this study we investigated the association between father-infant synchrony and infantsâ vagal tone in 77 dyads made up of fathers and their 3-month-old infants, considering the moderating roles of dyadic time and social time. Results revealed no direct associations between father-infant synchrony and infantsâ vagal tone. Moderation analyses revealed that more social time increases the association between synchrony and vagal tone. This result indicates a potential influence of family interactive processes
Interactive synchrony and infantsâ vagal tone as an index of emotion regulation ::associations within each mother-and father-infant dyad and across dyads
Introduction: Studies have shown that infantsâ emotion regulation capacities are closely linked to the quality of parent-infant interactions.

The associations between synchrony and infant vagal tone within father-infant dyads never appeared to be significant, nor did any associations within each dyad and across dyads when mothers interacted first. Discussion: This study highlights that the links between interactions and infantsâ vagal tone are sensitive to family membersâ interdependencies and some conditions (the order of interaction)
