Influence of dyadic matching of affect on infant self-regulation

Theory of Mind in Pre-school Aged Children: Influence of Maternal Depression and Infants' Self-Comforting Behavior

A milestone of child development is theory of mind (ToM): the ability to attribute mental states, especially beliefs and desires, to other persons and to understand that their behavior is guided by mental states. The learning process about the mental world also takes place in social communication and interaction, beginning in infancy. Infancy is assumed to be a sensitive period for the development of social skills through interaction. Due to limited self-regulatory skills, infants depend on sensitive behavior of their caregivers to regulate affective states and physiological arousal, and in turn, mutually regulated affects allow the infant to gradually acquire the capability to self-regulate negative affective states. Effective and adequate affect regulation is an important prerequisite for environmental interaction and thus for the development of socio-emotional skills. The present study investigated the relation of self-regulatory abilities in infancy and later ToM in pre-school aged children of clinically depressed mothers and healthy controls. The sample comprised of N = 55 mother-child dyads, n = 22 diagnosed with postpartum or lifetime depression according to DSM-IV and n = 33 healthy controls. Mother-infant-interaction was videotaped during the Face-to-Face Still-Face paradigm. At 3 and 42 months postpartum mothers were interviewed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to evaluate maternal psychopathological status according to DSM-IV. At the age of M = 4.0 years, children's ToM abilities were assessed using content-false-belief and location-false-belief tasks. The results of this study show that contrary to our hypotheses, maternal depression did not impair the development of children's ToM-abilities per se. Rather, an interaction effect highlights the role of infant's self-comforting behavior during mother-infant interaction in infancy (3 months postpartum) for ToM-development at pre-school age assessed with the Maxi-task; this association was distinct for female in comparison to male children. The results of this longitudinal study shed light on the discussion, how maternal depression influences child development and point in the direction that self-comforting behaviors in infancy can also be seen as a resource.

A method for measuring dynamic respiratory sinus arrhythmia (RSA) in infants and mothers

The measurement of respiratory sinus arrythmia (RSA) in infants, children and adults is critical to the study of physiological regulation, and more recently, interpersonal physiological covariation, but it has been impeded by methods that limit its resolution to 30 s or longer. Recent analytical developments have suggested methods for studying dynamic RSA in adults, and we have extended this work to the study of infants and mothers. In the current paper, we describe a new analytical strategy for estimating RSA time series for infants and adults. Our new method provides a means for studying physiological synchrony in infant-mother dyads that offers some important advantages relative to existing methods that use inter-beat-intervals (e.g. Feldman, Magori-Cohen, Galili, Singer, & Louzoun, 2011). In the middle sections of this paper, we offer a brief tutorial on calculating RSA continuously with a sliding window and review the empirical evidence for determining the optimal window size. In order to confirm the reliability of our results, we briefly discuss testing synchrony by randomly shuffling the dyads to control for spurious correlations, and also by using a bootstrapping technique for calculating confidence intervals in the cross-correlation function. One important implication that emerges from applying this method is that it is possible to measure both positive and negative physiological synchrony and that these categorical measures are differentially predictive of future outcomes.

Maternal and Infant Performance on the Face-to-Face Still-Face Task following Maternal Cognitive Behavioral Therapy for Postpartum Depression

OBJECTIVE

This study examined the impact of treating postpartum depression (PPD) with cognitive-behavioral therapy (CBT) on mother and infant behavior on the face-to-face still-face (FFSF) paradigm.

METHODS

Data from 68 mothers and their infants, 35 women with PPD within 12 months of delivery, and 33 healthy control dyads matched on infant age, sex and familial socioeconomic status were examined. Women with PPD received nine weeks of group CBT and were compared with healthy control dyads with at three timepoints on changes in mother-infant performance on the FFSF.

RESULTS

A significant group x FFSF phase x visit interaction was observed for infant withdrawn behavior at the three months post-treatment (p=0.006). Infants of mothers with PPD displayed significantly less withdrawn behavior after treatment, normalizing to levels of control infants.

LIMITATIONS

A relatively small sample consisting predominantly of Caucasian mother-infant dyads and the presence of comorbid anxiety in the PPD group.

CONCLUSION

Three months after group CBT for PPD, infants' withdrawn behavior appears to normalize to levels seen in the infants of healthy controls. Future studies should investigate whether treatments focused on the mother-infant dyad have distinctive effects on mothers and their infants' behaviors.

DYSFUNCTIONS IN THE SOCIO EMOTIONAL DEVELOPMENT OF INFANTS AND ITS RELATED FACTORS: AN INTEGRATIVE REVIEW

ABSTRACT Objective: to synthesize factors related to dysfunctions in the socioemotional development of infants. Method: integrative review carried out between April and August 2016 with defined criteria for inclusion and exclusion of studies, search strategies, extraction and synthesis of data. The exposure factors underwent categorical thematic analysis and systematization according to the levels of the context (Microsystem, Mesosystem, Exosystem and Macrosystem) of the Bioecological Model of Human Development. Results: in the context of the Microsystem and Mesosystem, the factors found were: limitations in care; adversities in family relationships and in the social support and illness situation of the caregivers that influence the proximal processes. In the Exosystem and the Macrosystem, they were: social vulnerabilities of caregivers and fragilities of public policies that determine the material and social conditions of the family. Conclusion: the synthesis of evidence on exposure factors favors the construction of measurement scales of the contextual elements related to the social emotional development of young children. Beyond the milestones, present or not, in the evaluation of a child, these technologies can be predictive, with great potential of anticipation of the factors of exposure and prevention of developmental dysfunctions.

The impact of maternal anxiety disorder on mother-infant interaction in the postpartum period

Background

This study investigated whether postpartum anxiety disorder is associated to altered patterns of infant as well as maternal engagement in a Face-to-Face-Still-Face interaction (FFSF).

Sampling and methods

n = 39 women with postpartum DSM-IV anxiety disorder and n = 48 healthy mothers were videotaped during a FFSF with their infant (M = 4.1 months).

Results

Infants of the clinical group showed significantly less positive engagement during the play episode than infants of controls. This result depended on infant sex: male controls demonstrated more positive interaction than males of anxious mothers. There was no such effect for female infants who engaged significantly less positively during the play episode than males and did not change their positive engagement during the FFSF. These findings imply pronounced interactive positivity and early vulnerability to maternal anxiety symptoms in male infants. Only the infants of the controls showed the still-face effect. They also protested significantly more during the still-face, while the clinical infants’ protest increased significantly during the reunion. Women of both groups did not differ in their interaction. Maternal intrusiveness was associated to infant protest in the course of the FFSF.

Conclusions

Results suggest that mother-infant intervention should consider affect regulation and infant sex-specific characteristics in anxious mother-infant dyads.

Disentangling the Dyadic Dance: Theoretical, Methodological and Outcomes Systematic Review of Mother-Infant Dyadic Processes

Background: During the last decades, the research on mother-infant dyad has produced a great amount of data, methods and theories, which largely contributed to set a revolution in the way we look at developmental changes during infancy and childhood. Very different constructs depict the different aspects of the "dyadic dance" occurring between a mother and her infant; nonetheless, a comprehensive and consistent systematization of these concepts in a coherent theoretical landscape is still lacking. Aim: In the present work, we aim at disentangling the different theoretical and methodological definitions of 9 dyadic constructs and we highlight their effects on infants' and children developmental outcomes. Methods: A literature search has been conducted on three databases-PubMed, Scopus, Web of Science. Three different reviews are reported here: (1) a review on the theoretical definitions of dyadic constructs; (2) a review of operational definitions, settings and methods of dyadic processes; (3) a systematic review of dyadic processes' outcomes for infants' and children developmental trajectories. Results: Two constructs emerged as wide meta-theoretical concepts (reciprocity and mutuality) and seven described specific processes (attunement, contingency, coordination, matching, mirroring, reparation, synchrony). A global model resuming the relationships among different processes is reported, which highlights the emergence of two specific cycles of dyadic functioning (i.e., matching-mismatching-reparation-synchrony; contingency, coordination, attunement, mirroring). A comprehensive review of the adopted measures is also provided. Finally, all the processes provided significant contributions to infants' behavioral, cognitive, and socio-emotional development during the first 3 years of age, but limited research has been conducted on specific processes (e.g. reparation and mirroring). Conclusion: The present study provides an original research-grounded framework to consider the different nature of mother-infant dyadic processes within a unified dyadic eco-system. Different levels of evidence emerged for the role of diverse mother-infant dyadic processes on infants' and children development. Open questions and future research directions are highlighted.

Effects of Maternal Anxiety Disorders on Infant Self-Comforting Behaviors: The Role of Maternal Bonding, Infant Gender and Age

BACKGROUND/AIMS

We investigated the links between maternal bonding, maternal anxiety disorders, and infant self-comforting behaviors. Furthermore, we looked at the moderating roles of infant gender and age.

METHODS

Our sample (n = 69) comprised 28 mothers with an anxiety disorder (according to DSM-IV criteria) and 41 controls, each with their 2.5- to 8-month-old infant (41 females and 28 males). Infant behaviors were recorded during the Face-to-Face Still-Face paradigm. Maternal bonding was assessed by the Postpartum Bonding Questionnaire.

RESULTS

Conditional process analyses revealed that lower maternal bonding partially mediated between maternal anxiety disorders and increased self-comforting behaviors but only in older female infants (over 5.5 months of age). However, considering maternal anxiety disorders without the influence of bonding, older female infants (over 5.5 months of age) showed decreased rates of self-comforting behaviors, while younger male infants (under 3 months of age) showed increased rates in the case of maternal anxiety disorder.

CONCLUSIONS

The results suggest that older female infants (over 5.5 months of age) are more sensitive to lower maternal bonding in the context of maternal anxiety disorders. Furthermore, results suggest a different use of self-directed regulation strategies for male and female infants of mothers with anxiety disorders and low bonding, depending on infant age. The results are discussed in the light of gender-specific developmental trajectories.

What Dyadic Reparation Is Meant to Do: An Association with Infant Cortisol Reactivity

BACKGROUND

The latency to reparation of interactive mismatches (interactive repair) is argued to regulate infant distress on a psychobiological level, and maternal anxiety disorders might impair infant regulation.

SAMPLING AND METHODS

A total of 46 dyads (19 mothers with an anxiety disorder, 27 controls) were analyzed for associations between interactive repair and infant cortisol reactivity during the Face-to-Face-Still-Face paradigm 3-4 months postpartum. Missing cortisol values (n = 16) were imputed. Analyses were conducted on both the original and the pooled imputed data.

RESULTS

Interactive repair during the reunion episode was associated with infant cortisol reactivity (original data: p < 0.01; pooled data: p < 0.01) but not maternal anxiety disorder (p > 0.23). Additional stepwise regression analyses found that latency to repair during play (p < 0.01), an interaction between distress during the first trimester of pregnancy and latency to repair during reunion (p < 0.01) and infant self-comforting behaviors during the reunion episode (p = 0.04) made independent contributions to cortisol reactivity in the final regression model.

CONCLUSIONS

This is the first study demonstrating that interactive repair is related to infant psychobiological stress reactivity. The lack of a relation to maternal anxiety disorder may be due to the small sample size. However, this result emphasizes that infants respond to what they experience and not to the maternal diagnostic category.
