Early home intervention and socio-emotional development of preterm infants

In the present study, the effects of developmental intervention and parent-infant interaction intervention on the social competence and emotional development of preterm infants were assessed. The results suggest that early home intervention focused on the infant's development facilitates social competence and adaptation, whereas intervention focused on the parent-infant interaction resulted in greater emotional security on the part of the infant. Social competence during the second year of life was predicted by social competence at 8 months and emotional security at 12 and 16 months. These findings have implications for early identification of infants at risk of later socio-emotional difficulties and intervention with dysfunctional mother-infant dyads.     

Emotional Relationships in Mothers and Infants: Culture-Common and Community-Specific Characteristics of Dyads from Rural and Metropolitan Settings in Argentina, Italy, and the United States

This study uses country and regional contrasts to examine culture-common and community-specific variation in mother-infant emotional relationships. Altogether, 220 Argentine, Italian, and U.S. American mothers and their daughters and sons, living in rural and metropolitan settings, were observed at home at infant age 5 months. Both variable- and person-centered perspectives of dyadic emotional relationships were analyzed. Supporting the notion that adequate emotional relationships are a critical and culture-common characteristic of human infant development, across all samples most dyads scored in the adaptive range in terms of emotional relationships. Giving evidence of community-specific characteristics, Italian mothers were more sensitive, and Italian infants more responsive, than Argentine and U.S. mothers and infants; in addition, rural mothers were more intrusive than metropolitan mothers, and rural dyads more likely than expected to be classified as mid-range in emotional relationships and less likely to be classified as high in emotional relationships. Adaptive emotional relationships appear to be a culture-common characteristic of mother-infant dyads near the beginning of life, but this relational construct is moderated by community-specific (country and regional) context.     

Associations between mother-infant bed-sharing practices and infant affect and behavior during the still-face paradigm

Parents in the United States increasingly report bed-sharing with their infants (i.e., sleeping on a shared sleep surface), but the relationship between bed-sharing and child socioemotional outcomes are not well understood. The current study examines the links between mother-infant bed-sharing at 3 months and infant affect and behavior during a dyadic challenge task at 6 months. Further, we examine nighttime mother-infant contact at 3 months as a possible mechanism that may mediate linkages between bed-sharing and infant outcomes. Using observational data from a sample of 63 mother-infant dyads, we found that infants who bed-shared for any proportion of the observation period at 3 months displayed significantly more self-regulatory behaviors during the still-face episode of the Still-Face Paradigm (SFP) at 6 months, compared to non-bed-sharing infants. Also, infants of mothers who bed-shared for the entire observation period displayed significantly less negativity during the reunion episode than non-bed-sharing infants. There was no evidence that the relations between mother-infant bed-sharing practices and infant affect and behavior during the SFP were mediated through nighttime mother-infant contact. Results suggest that infant regulation at 6 months postpartum may vary based on early nighttime experiences, with bed-sharing potentially promoting more positive and well-regulated behavior during dyadic interaction.     

The role of oxytocin in early mother-infant interactions: Variations in maternal affect attunement

The aim of the present research was to investigate the relationship between oxytocin and maternal affect attunement, as well as the role of affect attunement in the relationship between oxytocin and infant social engagement during early mother-infant interactions. Forty-three mother-infant dyads participated in the present study when infants were 4 months. They were observed during (1) a situation where no communication took place and (2) a natural interaction between mother and infant. During this procedure, three saliva samples from mothers and their infants were collected to determine their levels of oxytocin at different time points. Maternal affect attunement (maintaining attention, warm sensitivity) and infant interactive behaviors (gaze, positive, and negative affect) were coded during the natural interaction. Results indicated that overall maternal oxytocin functioning was negatively related to her warm sensitivity, while infant oxytocin reactivity together with maternal affect attunement were associated with infant positive social engagement with their mothers. Specifically, infant oxytocin reactivity was significantly related to their gazes at mother, but only for infants of highly attuned mothers. These results point to the complex role oxytocin plays in parent-infant interactions while emphasizing the need to analyze both overall oxytocin functioning as well as reactivity as different indices of human affiliative behavior.     

Mutual visual regard during mother-infant play.

Mutual visual regard was observed in 48 mother-infant dyads during a 6-min. play session. Infant-mother dyads containing 4 mo. -olds displayed significantly more mutual visual regard than dyads containing 6- or 8-mo.-olds. In addition, the more time infants spent in face-to-face interaction with mother, the more smiling they engaged in. No sex difference were observed.     

Maternal psychosocial predictors of pacifier use in a mother-infant interaction task: An observational study from the MPEWS pregnancy cohort

The prevalence of pacifier use is high but when it occurs outside of the recommended sleep context, it becomes more controversial. Using 211 mother-infant dyads recorded as part of the Mercy Pregnancy and Emotional Wellbeing Study, we examined the maternal psychosocial predictors of pacifier use within an interaction task (i.e., ten minutes face-to-face followed by 30-minutes unstructured play). Predictors included maternal emotional availability measured with the Emotional Availability Scales; depression measured by the Structured Clinical Interview for the DSM-IV-TR Clinician Version; and maternal history of childhood trauma measured by the Childhood Trauma Questionnaire. An unadjusted odds ratio demonstrated that women classified as non-emotionally available to their infants were three-and-a-half-times more likely to use a pacifier. Multivariate logistic regression including all maternal psychosocial predictors demonstrated that even when adjusting for cessation of breastfeeding, maternal emotional availability remained the only significant predictor of pacifier use. This is the first time that predictors of pacifier use have been examined with a sample of clinically depressed women, as well as women with childhood trauma history. The results provide preliminary evidence that women who are not emotionally available might be more likely to rely on a pacifier during mother-infant interaction.     

Using a Technological Augmentation to Enhance Parent-Infant Interactions With Parents at Risk

ABSTRACT

Effective parent training programs may need to be tailored for at-risk parents by using simple language, presenting concrete concepts, and simple technologies. We present four single-case research-design studies examining if the use of digital frames enhances parent-infant interactions with a diverse range of mothers with varied levels of risk for maltreatment. Based on self-modeling, the frames contain photographs of mother-infant dyads in posed interactions representing desired criterion behaviors from the parent-infant interaction (PII) module of SafeCare®. Results indicate that the use of inexpensive digital frames appears to enhance already good outcomes of the SafeCare PII module.     

Responsiveness in mother-infant social interactions among immigrant and nonmigrant families: Japanese,South Korean,South American,and European American

A culture learning perspective motivated the present study of the acculturation of responsiveness in mother-infant interactions. Several conceptual and analytic features of responsiveness in mother-infant social interactions were examined: Temporal contingency, mean differences in responsiveness among and within dyads, attunement of mother and infant responsiveness withing dyads, and the influence of acculturation on individual responsiveness. Methodologically, acculturation was assessed at group and individual levels in immigrant Japanese, South Korean, and South American dyads in comparison with nonmigrant dyads in their respective cultures of origin (Japan, South Korea, and South America) and their single common culture of destination (United States). In total, 408 mothers and their 5½-month-old infants were observed in the naturalistic setting of the home, and observations were coded for mothers’ speech to infant, social play, and encouraging her infant to look at her, and infants’ looking at mother and nondistress vocalizations. Odds ratios were then generated for mother and infant responsiveness in four types of social interactions: Mother speaks to infant and infant looks at mother (Mother Speak/Infant Attend), mother plays with infant and infant looks at mother (Mother Play/Infant Attend), mother plays with infant and infant vocalizes (Mother Play/Infant Vocalize), and mother encourages infant to look at her and infant vocalizes (Mother Encourage/Infant Vocalize). Five key findings emerged. Specifically, mother and infant responsiveness in Mother Speak/Infant Attend interactions were temporally contingent in all cultures. Mean differences in responsiveness among cultures emerged, and within dyads infants were more responsive than their mothers in Mother Speak/Infant Attend interactions. Mother and infant responsiveness in Mother Speak/Infant Attend interactions were attuned in all cultures. Responsiveness in Mother Play/Infant Vocalize interactions showed acculturation effects at the individual level. Implications of these findings for understanding the development of responsiveness in social interactions and acculturation in immigrant families are discussed.     

Synchrony in mother-infant vocal interactions revealed through timed event sequences

This report extends a previous cross-cultural study of synchrony in mother-infant vocal interactions (Bornstein et al., 2015) to immigrant samples. Immigrant dyads from three cultures of origin (Japan, South Korea, South America) living in the same culture of destination (the United States) were compared to nonmigrant dyads in those same cultures of origin and to nonmigrant European American dyads living in the same culture of destination (the United States). This article highlights an underutilized analysis to assess synchrony in mother-infant interaction and extends cross-cultural research on mother-infant vocal interaction. Timing of onsets and offsets of maternal speech to infants and infant nondistress vocalizations were coded separately from 50-min recorded naturalistic observations of mothers and infants. Odds ratios were computed to analyze synchrony in mother-infant vocal interactions. Synchrony was analyzed in three ways -- contingency of timed event sequences, mean differences in contingency by acculturation level and within dyads, and coordination of responsiveness within dyads. Immigrant mothers were contingently responsive to their infants’ vocalizations, but only Korean immigrant infants were contingently responsive to their mothers’ vocalizations. For the Japanese and South American comparisons, immigrant mothers were more contingently responsive than their infants (but not robustly so for South American immigrants). For the Korean comparison, mean differences in contingent responsiveness were found among acculturation groups (culture of origin, immigrant, culture of destination), but not between mothers and infants. Immigrant dyads’ mean levels of responsiveness did not differ. Immigrant mothers’ and infants’ levels of responsiveness were coordinated. Strengths and flexibility of the timed event sequential analytic approach to assessing synchrony in mother-infant interactions are discussed, particularly for culturally diverse samples.     

Weaning in Japan: A longitudinal study of mother and child behaviours during milk- and solid-feeding

Behaviours of seven Japanese mother-infant dyads during daytime feeding of both milk and solids were observed longitudinally to the middle of the second year. The first 3 months were a period of exclusive milk-feeding largely uninterrupted by mother-infant social interaction. In the following 6 months there was increasing mother-infant communicative interaction during milk-feeding and the mother began attempts to feed solids. After 8 months, weaning was promoted by reduction in some types of interaction during milk-feeding, and increased rejection by the infant of passive feeding as self-feeding of solids increased. Self-feeding was at first mainly by hand, and later with tools. A positive correlation was found between hand-feeding at 12-14 months and active physical stimulation of the infant by the mother during milk-feeding in the first year. Self-feeding of solids with tools increased significantly after 1 1/2 years, and the mother supported this development. The mother showed non-intentional eating-like mouth movement at the moment infants ate (empathetic behaviour), and this behaviour peaked in the latter half of the first year and decreased thereafter. The development of independence or autonomy in feeding was a mutual or cooperative process between mother and infant, and was initiated by the infant rather than imposed by the mother.     

Mother-child emotional availability in ecological perspective: three countries, two regions, two genders

This study used a cross-national framework to examine country, region, and gender differences in emotional availability (EA), a prominent index of mutual socioemotional adaptation in the parent-child dyad. Altogether 220 Argentine, Italian, and U.S. mothers and their daughters and sons from both rural and metropolitan areas took part in home observations when the children were 20 months old. In terms of country, Italian mothers were more sensitive and optimally structuring, and Italian children were more responsive and involving, than Argentine and U.S. dyads. In terms of region, rural mothers were more intrusive than metropolitan mothers, and boys from metropolitan areas were more responsive than boys from rural areas. In terms of gender, mothers of girls were more sensitive and optimally structuring than mothers of boys, and daughters were more responsive and involving than sons. Understanding how country, region, and gender influence EA exposes forces that shape child development, parent-infant interaction, and family systems.     

The coregulatory effects of emotionally focused therapy

This study examined the heart rate synchrony between a single couple in emotionally focused therapy (EFT) as a method of measuring coregulatory effects over the course of treatment. A clinician who is an EFT certified therapist, supervisor, and trainer administered all eight sessions in a private practice setting. Surrogate synchrony analysis assessed heart rate synchrony between partners, indicating that significant heart rate synchrony was more likely over time. Significant heart rate synchrony was more likely during sessions that focused on clients’ sharing attachment injuries, bonds, and longings with their partner compared to sessions more focused on cognitive processing of the relationship. Additionally, there were delays in heart rate synchrony that occurred between the couple, which may be indicative of the emotional processing speed of the empathic response of each partner. Understanding the physiological synchrony patterns between dyads in treatment could clarify the potential of coregulation in the therapeutic process.     

Digital disruption? Maternal mobile device use is related to infant social‐emotional functioning

Mobile device use has become increasingly prevalent, yet its impact on infant development remains largely unknown. When parents use mobile devices in front of infants, the parent is physically present but most likely distracted and unresponsive. Research using the classic Still Face Paradigm (SFP) suggests that parental withdrawal and unresponsiveness may have negative consequences for children's social‐emotional development. In the present study, 50 infants aged 7.20 to 23.60 months (M = 15.40, SD = 4.74) and their mothers completed a modified SFP. The SFP consisted of three phases: free play (FP; parent and infant play and interact), still face (SF; parent withdraws attention and becomes unresponsive), and reunion (RU; parent resumes normal interaction). The modified SFP incorporated mobile device use in the SF phase. Parents reported on their typical mobile device use and infant temperament. Consistent with the standard SFP, infants showed more negative affect and less positive affect during SF versus FP. Infants also showed more toy engagement and more engagement with mother during FP versus SF and RU. Infants showed the most social bids during SF and more room exploration in SF than RU. More frequent reported mobile device use was associated with less room exploration and positive affect during SF, and less recovery (i.e., engagement with mother, room exploration positive affect) during RU, even when controlling for individual differences in temperament. Findings suggest that the SFP represents a promising theoretical framework for understanding the impact of parent's mobile device use on infant social‐emotional functioning and parent–infant interactions.     

Father-Child and Mother-Child Interactions with Children with Anxiety Disorders: Emotional Expressivity and Flexibility of Dyads

This observational study examined whether emotional expressivity and emotional flexibility differed between parent-child dyads with and without children with an anxiety disorder (AD). Effects of parents’ own AD on emotional expressivity and flexibility of dyads was also studied. The sample consisted of 128 referred children (59.4% girls) with an AD (8–18-year-olds) and both of their parents, and 44 matched non-AD children (63.6% girls) and both of their parents. Father-child and mother-child dyads were videotaped while discussing a conflict. Measures of dyadic emotional expressivity (positive and negative affect) and dyadic emotional flexibility (transitions, dispersion, average duration) were derived from these interactions using state space grid analysis. No differences existed in emotional expressivity of parent-child dyads with or without AD children, however both father-child and mother-child dyads with a child with an AD displayed less emotional flexibility during interactions than healthy controls. Mother-child dyads where both mother and child had AD showed more emotional expressivity and less emotional flexibility compared to mother-child dyads with only AD children and to dyads without AD. In particular, the inability to flexibly move in and out of different emotions distinguishes healthy dyads from non-healthy dyads. Targeting emotional flexibility of dyads with children with an AD, and also emotional expressivity of dyads when mother has an AD, might be a valuable goal for family-based intervention.     

The association between maternal smoking and secondhand exposure and autonomic functioning at 2-4 weeks of age

This study examined the association between maternal smoking and exposure to environmental tobacco smoke (ETS) during pregnancy and infant heart rate. Participants were 62 mother-infant dyads where mother smoked during pregnancy, 47 dyads where mother did not smoke during pregnancy but was exposed to ETS and 47 dyads where mother did not smoke and was not exposed to ETS. Average heart rate (HR) and respiratory sinus arrhythmia (RSA) were assessed at 2-4 weeks of age during sleep. Infants in both exposure groups had higher HR and lower RSA than nonexposed infants. Furthermore, boys in both exposure groups had higher HR and lower RSA than girls. These results highlight the importance of considering prenatal ETS exposure and infant gender when assessing infant outcomes.     

Parent-infant synchrony and the social-emotional development of triplets

To study the social-emotional development of triplets, 23 sets of triplets, 23 sets of twins, and 23 singleton infants (N=138) were followed from birth to 2 years. Maternal depression and social support were assessed in the postpartum period, mother-infant and father-infant interaction and the home environment were observed at 3 months, a separation-reunion episode and a maternal interview were conducted at 12 months, and infant behavior problems were evaluated at 24 months. Lower parent-infant synchrony was observed for triplets. Triplets showed less distress during maternal separation and less approach at reunion. Mothers reported lower adjustment and differentiation among siblings for triplets than for twins. Higher internalizing problems were reported for triplets, and the triplet with intrauterine growth retardation showed the poorest outcomes. Behavior problems were predicted by medical risk, maternal depression, parent-infant synchrony, infant approach, and mother adjustment. Discussion focuses on developmental risk when the exclusivity of the parent-infant relationship is compromised.     

Antecedents of mirror self‐recognition of toddlers: Emotional availability,birth order,and gender

The present study employed a longitudinal design for examining the role of emotional availability of child–mother dyads, birth order of children, and their gender as determinants of mirror self‐recognition of toddlers. It was hypothesized that toddlers who maintained more optimal emotional availability with mother at the age of 12 months would tend to identify themselves more readily at the age of 20 months. We assumed further that first‐born children and females would identify themselves more readily than males and younger siblings. A sample of 54 nonrisk children and their mothers was investigated. Path analysis model showed that emotional availability partly predicted self‐recognition: responsive toddlers identified themselves more often than less responsive peers. No significant effects were found for the other scales of emotional availability. A nonlinear birth order effect was observed, with second‐born children being less likely to show mirror self‐recognition than first‐borns or third‐borns. Child gender was not significantly associated with self‐recognition at the age of 20 months. The data showed further that birth order was significantly linked with components of emotional availability. No significant correlations were found between emotional availability scores and child gender. Results were discussed in light of the different components of emotional availability, and the psychological correlates of ordinal position in the family. ©2002 Michigan Association for Infant Mental Health.     

Cardiovascular correlates of emotional expression and suppression: do content and gender context matter?

Three studies examined cardiovascular (CV) responses during emotional expression with empathically responsive strangers. Study 1 demonstrated that self-relevant emotional expression fostered CV reactivity consistent with challenge. Study 2 manipulated content of discussion by assigning participants to 1 of 4 conditions: emotional, nonemotional, emotional suppression, nonemotional suppression. In same-sex dyads. emotional expression elicited CV challenge reactivity whereas emotional suppression evoked CV threat reactivity, both compared with appropriate control groups. In opposite-sex dyads, however, emotional expression engendered CV threat. Because same- and opposite-sex disclosures differed, Study 3 controlled the content of emotional expression while manipulating gender context. Results confirmed findings from the first 2 studies, indicating that both context and content of emotional expression influenced CV effects. Findings are discussed within a theoretical challenge and threat perspective.     

Maternal postnatal psychiatric symptoms and infant temperament affect early mother-infant bonding

Postnatal mother-infant bonding refers to the early emotional bond between mothers and infants. Although some factors, such as maternal mental health, especially postnatal depression, have been considered in relation to mother-infant bonding, few studies have investigated the role of infant temperament traits in early bonding. In this study, the effects of maternal postnatal depressive and anxiety symptoms and infant temperament traits on mother-infant bonding were examined using both mother and father reports of infant temperament. Data for this study came from the first phase of the FinnBrain Birth Cohort Study (n = 102, father reports n = 62). After controlling for maternal symptoms of depression and anxiety, mother-reported infant positive emotionality, measured by infant smiling was related to better mother-infant bonding. In contrast, infant negative emotionality, measured by infant distress to limitations was related to lower quality of bonding. In regards to father-report infant temperament, only infant distress to limitations (i.e., frustration/anger) was associated with lower quality of mother-infant bonding. These findings underline the importance of infant temperament as one factor contributing to early parent-infant relationships, and counseling parents in understanding and caring for infants with different temperament traits.     

Student volunteer social support and infant intervention: A case study

The emphases in infant mental health have been in the three areas of supporting the mother-infant dyad through education, psychotherapy to help parents resolve emotional conflicts that interfere with the parent-infant interaction, and support during the acute crisis that follows an abnormal birth. The case described herein involves a child with a genetic defect born to competent parents, a chronic stressful situation that does not fit these categories. It became apparent in the first few months after the birth that both the child and parents were in need of some help in coping with the situation. An intervention was designed to help provide both the necessary stimulation for the baby and the needed emotional support for the family, while it acknowledged their skill and competencies as parents. This was done through the help of college student volunteers, who assisted the mother in the home. Developmental data recorded at birth, 7 months, 12 months, and 39 months indicate that the child is severely multiply handicapped. Interview data with the parents at those times document their personal and family difficulties, the eventual resolution as a family in dealing with this problem, and the importance of the volunteer help during that process.
