Prematurity, maternal stress and mother-child interactions

Early mother-infant interactions within the context of childbirth-related posttraumatic stress symptoms

BACKGROUND

Childbirth may lead to perinatal mental health issues, such as childbirth-related posttraumatic stress symptoms (CB-PTSS), depression, and anxiety. Despite well explored mother-infant interactions in the context of maternal depression and anxiety, only limited studies investigated mother-infant interactions in the context of CB-PTSS, which is the aim of the present study.

METHODS

One-hundred mother-infant dyads in the French speaking part of Switzerland were classified into three groups: birth-related symptoms (BRS, i.e., symptoms of re-experiencing and avoidance) (n = 20), general symptoms (GS, i.e., symptoms of negative cognition and mood and hyperarousal) (n = 46), and non-symptomatic (NS) (n = 34) based on maternal report on PTSD Checklist for DSM-5 (PCL-5). At six months postpartum, mother-infant interactions were video-recorded and their quality was assessed using the Global Rating Scale. Data was analyzed using ordinal logistic and negative binomial regressions.

RESULTS

In the adjusted model, mothers in BRS group engaged in more frequent coercions compared to the NS group (B = -1.46, p = 0.01, 95%CI = -2.63, -0.36) and showed lower reciprocity in their interactions with their infants compared to the GS group (B = 1.21, p = 0.03, 95%CI = 0.05, 2.37).

LIMITATIONS

The use of a cross-sectional design limited the exploration of how consistent these findings are regarding mother-infant interactions between groups over time.

CONCLUSIONS

Mothers with higher BRS may need support to improve interactions with their infants. Future studies should consider longitudinal design to observe mother-infant interaction changes between CB-PTSS groups over time.

Protective and vulnerability personality traits associated with PTSD diagnosis after preterm delivery

Giving birth prematurely is a traumatic event that has many consequences for the mother but also for her baby and their family. Studies have shown that about a quarter of these mothers will suffer from post-traumatic stress disorder (PTSD) as a result. This study aims to identify internal personality factors associated with the development of PTSD in mothers who gave birth before 33 weeks. The results revealed significant correlations between two personality dimensions (neuroticism and extraversion) and the likeliness of developing PTSD in mothers who gave birth prematurely. Neuroticism is positively liked with the disorder while extraversion is negatively correlated with it. Studies should now focus on early detection of PTSD and better interventions for these mothers.

Longstanding Auditory Sensory and Semantic Differences in Preterm Born Children

More than 10% of births are preterm, and the long-term consequences on sensory and semantic processing of non-linguistic information remain poorly understood. 17 very preterm-born children (born at < 33 weeks gestational age) and 15 full-term controls were tested at 10 years old with an auditory object recognition task, while 64-channel auditory evoked potentials (AEPs) were recorded. Sounds consisted of living (animal and human vocalizations) and manmade objects (e.g. household objects, instruments, and tools). Despite similar recognition behavior, AEPs strikingly differed between full-term and preterm children. Starting at 50ms post-stimulus onset, AEPs from preterm children differed topographically from their full-term counterparts. Over the 108-224ms post-stimulus period, full-term children showed stronger AEPs in response to living objects, whereas preterm born children showed the reverse pattern; i.e. stronger AEPs in response to manmade objects. Differential brain activity between semantic categories could reliably classify children according to their preterm status. Moreover, this opposing pattern of differential responses to semantic categories of sounds was also observed in source estimations within a network of occipital, temporal and frontal regions. This study highlights how early life experience in terms of preterm birth shapes sensory and object processing later on in life.

[Post-hospital support for families: current situation and outlook]

After neonatal hospitalization, our healthcare system offers multidisciplinary care for premature babies and their families during the first years of life. However, there are disparities and gaps, particularly in the case of medium prematurity. Maternal and child protection, a major player in early prevention and family follow-up, is a partner likely to be able to deploy post-hospital support perspectives in favor of child development and parenting support.

Joint observation in NICU (JOIN): A randomized controlled trial testing an early, one-session intervention during preterm care to improve perceived maternal self-efficacy and other mental health outcomes

BACKGROUND

Parents of preterm infants in the Neonatal Intensive Care Unit (NICU) environment may experience psychological distress, decreased perceived self-efficacy, and/or difficulties in establishing an adaptive parent-infant relationship. Early developmental care interventions to support the parental role and infant development are essential and their impact can be assessed by an improvement of parental self-efficacy perception. The aims were to assess the effects of an early intervention provided in the NICU (the Joint Observation) on maternal perceived self-efficacy compared to controls (primary outcome) and to compare maternal mental health measures (perceived stress, anxiety, and depression), perception of the parent-infant relationship, and maternal responsiveness (secondary outcomes).

METHODS

This study was a monocentric randomized controlled trial registered in clinicatrials.gov (NCT02736136), which aimed at testing a behavioural intervention compared with treatment-as-usual. Mothers of preterm neonates born 28 to 32 6/7 weeks gestation were randomly allocated to either the intervention or the control groups. Outcome measures consisted of self-report questionnaires completed by the mothers at 1 and 6 months after enrollment and assessing perceived self-efficacy, mental health, perception of the parent-infant relationship and responsiveness, as well as satisfaction with the intervention.

RESULTS

No statistically significant group effects were observed for perceived maternal self-efficacy or the secondary outcomes. Over time, perceived maternal self-efficacy increased for mothers in both groups, while anxiety and depression symptoms decreased. High satisfaction with the intervention was reported.

CONCLUSIONS

The joint observation was not associated with improved perceived maternal self-efficacy or other mental health outcomes, but may constitute an additional supportive measure offered to parents in a vulnerable situation during the NICU stay.

Preterm toddlers' joint attention characteristics during dyadic interactions with their mothers and fathers compared to full-term toddlers at age 2 years

The current study investigates Joint Attention (JA) characteristics (duration, frequency, source of initiation, type of JA, agent of termination, missed and unsuccessful episodes) in preterm and full-term toddlers' interactions with their mothers and fathers, separately. Thirty-one singleton full-term (Mage = 24.07 months, SD = 1.45; 13 boys) and 17 singleton preterm toddlers (Madjustedage = 24.72 months, SD = 3.39; 12 boys) participated in the study with both parents. JA episodes were examined during dyadic five-minute free play sessions, were coded second-by-second, and were analysed using two-way mixed ANOVAs. Although the total amount of time spent in JA was not significantly different between the preterm and the full-term groups, JA episodes were more frequent, specifically supported JA episodes, and were more often terminated by the child during parent-preterm toddler interactions. Moreover, preterm toddlers missed their fathers' attempts for JA more often than their mothers' and more often than full-term toddlers missed their fathers' and mothers' bids for JA. Further, regardless of the birth status, toddlers initiated more JA with mothers than fathers, and fathers redirected their child's attention to initiate JA more than mothers. Findings indicate that preterm toddlers may struggle to respond to JA bids, especially with their fathers, and to sustain their attention on a specific object or event during interactions. Preterm toddlers may need more support to engage in JA relative to their full-term peers, and redirecting attention strategy may not be optimal for them. Also, toddlers' JA interactions may be different with their mothers and fathers. Findings contribute to the literature by demonstrating preterm toddlers' JA characteristics with both parents compared to full-term toddlers at age two.

Infant-Directed Speech to Preterm Infants during the First Year Postpartum: The Influence of Preterm Birth Weight and Maternal Parenting Stress

Premature birth can increase the level of parenting stress (PS), especially in the case of parents of high-risk infants (extremely low birth weight (ELBW) and very low birth weight (VLBW)). Though published research has explored how maternal PS influences early dyadic interactions, limited research has focused on infant-directed speech (IDS), and no studies have investigated the link between prematurity severity based on birth weight and maternal IDS. This study, involving 100 mother-infant dyads, categorized into 30 ELBW premature infants, 30 VLBW premature infants, and 40 full-term (FT) ones, examined the impact of preterm birth weight and maternal parenting stress on IDS features during early interactions at 3 and 9 months postpartum. Maternal input was assessed using the CHILDES system, while parenting stress was evaluated using the Parenting Stress Index-Short Form. The results revealed that high-risk conditions (ELBW preterm birth and high parenting stress) at 3 months were associated with reduced affect-salient speech and increased questioning. IDS functional patterns, specifically the proportion of affect-salient speech and questions, were influenced by both birth weight groups and parenting stress levels at 3 months but not at 9 months. These findings highlight the need to assess, within the context of prematurity, both birth weight and parenting stress in clinical practice, offering insights for developing interventions supporting positive parent-infant interactions and facilitating infant development.

Attachment and mother-infant interactions in dyads with infants born full-term, moderate-to-late preterm, and very-to-extreme preterm

BACKGROUND

The impact of prematurity status on attachment quality remains indeterminate. Some studies found no differences between infants born preterm (PT) and infants born full-term (FT), while other investigations present opposite results.

AIMS

We aim to contribute to this body of research by studying mother-infant interactive behaviors and quality of attachment in 3 independent samples: Full-Term (FT), Moderate-to-Late Preterm (MLPT) and Very-to-Extreme Preterm (VEPT).

STUDY DESIGN

This is a longitudinal laboratory study conducted from 3 to 12 months of age (corrected-age in the case of infants born PT).

SUBJECTS

The participants are 213 Portuguese infants (FT = 105; MLPT = 52; VEPT = 56) and their mothers.

OUTCOME MEASURES

Mother-infant interactive behavior was observed in free-play at 3 and 9 months (corrected-age). Infant attachment was observed in Strange Situation at 12 months.

RESULTS

Secure attachment is more prevalent in infants born FT, and ambivalent attachment is more prevalent in infants born VEPT. Infants with a secure attachment have higher gestational age and weight at birth. Infant and maternal interactive behavior quality is associated with attachment patterns and varies according to infant prematurity status. Last, the results indicate changes in maternal sensitivity and infant difficult behavior from 3 to 9 months of infant's age.

CONCLUSIONS

Our findings indicate that prematurity status impacts attachment quality. Changes in maternal and infant behavior from 3 to 9 months suggest a period of rapid non-linear development, supporting a transactional multilayered approach to the study of mother-infant relationship.

Effect of tactile and/or kinesthetic stimulation therapy of preterm infants on their parents' anxiety and depressive symptoms: A systematic review

BACKGROUND

In the case of preterm birth, the idealized postnatal period is replaced by an anxious and even traumatic experience for parents. Higher prevalence of parental anxiety, postnatal depression, and posttraumatic stress disorder has been observed in mothers of preterm infants up to 18 months after childbirth. There is increasing evidence that proprioceptive stimulation has a beneficial effect on preterms' short-term outcomes. Could this care also have an impact on parental anxiety and depressive symptoms? We reviewed recent publications on the impact on parents' anxiety and depressive symptoms of delivering tactile and/or kinesthetic stimulation to their premature newborn.

METHODS

We conducted a systematic review by searching the PubMed, PsycInfo, Scopus, ScienceDirect and Google Scholar databases for English-language publications from the past 10 years. We focused on the mothers or fathers of infants born preterm (before 37 weeks of gestation) who provided tactile and/or kinesthetic stimulation to their premature newborn in the neonatal intensive care unit. Relevant outcomes were the parents' anxiety, stress, depressive symptoms, and symptoms of posttraumatic stress disorder, assessed with reliable standardized inventories.

RESULTS

Eleven articles were included in the systematic review. Results suggested a beneficial effect of parents' early tactile and kinesthetic stimulation of their preterm infants.

CONCLUSIONS

These interventions may act as protective factors against the occurrence of anxiety and depressive symptoms in parents and deserve to be studied further in this population.

Predicting attachment in Portuguese infants born very or extremely preterm: Understanding the roles of infant regulatory behavior, maternal sensitivity, and risk factors

A growing body of research shows that early attachment relationships are foundational for children's later developmental and psychosocial outcomes. However, findings are mixed regarding whether preterm birth predicts later attachment, but insecurity is generally more prevalent among infants at higher medical and/or social/familial risk. This longitudinal study aimed to identify specific relational, familial/demographic, and perinatal predictors of attachment in a sample of 63 Portuguese infants born very or extremely preterm (VEPT, <32 gestational weeks) and their mothers from diverse socioeconomic backgrounds. One-third of the mothers had social/family risk factors (e.g., single parent, immigrant, unemployed, low education, and/or low income). At 3 months (corrected age), dyads were observed during social interaction in the Face-to-Face Still-Face paradigm (FFSF) and during free play. At 12 months, mother-infant dyads were observed in Ainsworth's Strange Situation. Over half (58.7%) of the infants were classified as insecurely attached. Social-Positive Oriented regulatory behavior pattern, higher maternal sensitivity, higher infant cooperation during free play, number of siblings and an absence of social/family risk factors were associated with attachment security. Perinatal variables were unrelated to attachment. Findings indicate that both relational and social contextual factors contribute to attachment in this biologically vulnerable sample.

Effect of adverse perinatal outcomes on postpartum maternal mental health in low-income and middle-income countries: a protocol for systematic review

INTRODUCTION

More than three-fourths of adverse perinatal outcomes (preterm, small for gestational age, low birth weight, congenital anomalies, stillbirth and neonatal death) occur in low-income and middle-income countries. These adverse perinatal outcomes can have both short-term and long-term consequences on maternal mental health. Even though there are few empirical studies on the effect of perinatal loss on maternal mental illness, comprehensive information on the impact of adverse perinatal outcomes in resource-limited settings is scarce. Therefore, we aim to systematically review and synthesise evidence on the effect of adverse perinatal outcomes on maternal mental health.

METHODS AND ANALYSIS

The primary outcome of our review will be postpartum maternal mental illness (anxiety, depression, post-traumatic stress disorder and postpartum psychosis) following adverse perinatal outcomes. All peer-reviewed primary studies published in English will be retrieved from databases: PubMed, MEDLINE, CINAHL Ultimate (EBSCO), PsycINFO, Embase, Scopus and Global Health through the three main searching terms-adverse perinatal outcomes, maternal mental illness and settings, with a variant of subject headings and keywords. We will follow the Joanna Briggs Institute critical appraisal checklist to assess the quality of the studies we are including. The review findings will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. Estimate-based meta-analysis will be performed. We will assess heterogeneity between studies using the I2 statistics and publication bias will be checked using funnel plots and Egger's test. A subgroup analysis will be conducted to explore potential sources of heterogeneity (if available). Finally, the certainty of the evidence will be evaluated using the Grading of Recommendations, Assessment, Development and Evaluation approach.

ETHICS AND DISSEMINATION

Since this systematic review does not involve human participants, ethical approval is not required. The review will be submitted for publication in a peer-reviewed journal.

Preterm infant mental health in the neonatal intensive care unit: A review of research on NICU parent-infant interactions and maternal sensitivity

Caregiving relationships in the postnatal period are critical to an infant's development. Preterm infants and their parents face unique challenges in this regard, with infants experiencing separation from parents, uncomfortable procedures, and increased biologic vulnerability, and parents facing difficulties assuming caregiver roles and increased risk for psychological distress. To better understand the NICU parent-infant relationship, we conducted a review of the literature and identified 52 studies comparing observed maternal, infant, and dyadic interaction behavior in preterm dyads with full-term dyads. Eighteen of 40 studies on maternal behavior found less favorable behavior, including decreased sensitivity and more intrusiveness in mothers of preterm infants, seven studies found the opposite, four studies found mixed results, and 11 studies found no differences. Seventeen of 25 studies on infant behavior found less responsiveness in preterm infants, two studies found the opposite, and the remainder found no difference. Eighteen out of 14 studies on dyad-specific behavior reported less synchrony in preterm dyads and the remainder found no differences. We identify confounding factors that may explain variations in results, present an approach to interpret existing data by framing differences in maternal behavior as potentially adaptive in the context of prematurity, and suggest future areas for exploration.

Persistent symptoms of maternal post-traumatic stress following childbirth across the first months postpartum: Associations with perturbations in maternal behavior and infant avoidance of social gaze toward mother

Recent literature identifies childbirth as a potentially traumatic event, following which mothers may develop symptoms of Post-Traumatic-Stress-Following-Childbirth (PTS-FC). The current study examines whether stable symptoms of PTS-FC during the early postpartum period may impose risk for perturbations in maternal behavior and infant social-engagement with mother, controlling for comorbid postpartum internalizing symptoms. Mother-infant dyads (N = 192) were recruited from the general population, during the third trimester of pregnancy. 49.5% of the mothers were primipara, and 48.4% of the infants were girls. Maternal PTS-FC was assessed at 3-day, 1-month and 4-month postpartum, via self-report and clinician-administered interview. Latent Profile Analysis generated two profiles of symptomology: "Stable-High-PTS-FC" (17.0%), and "Stable-Low-PTS-FC" (83%). Membership in the "Stable-High-PTS-FC" profile associated with perturbed maternal sensitivity, which was in turn significantly associated with infant avoidance of social gaze toward mother (Indirect effect β = -0.15). Results suggest the need for early screening and inform the planning of early preventive interventions.

Sitting Capacity and Performance in Infants with Typical Development and Infants with Motor Delay

AIMS

Infants with neuromotor disorders demonstrate delays in sitting skills (decreased capacity) and are less likely to maintain independent sitting during play than their peers with typical development (decreased performance). This study aimed to quantify developmental trajectories of sitting capacity and sitting performance in infants with typical development and infants with significant motor delay and to assess whether the relationship between capacity and performance differs between the groups.

METHODS

Typically developing infants (n = 35) and infants with significant motor delay (n = 31) were assessed longitudinally over a year following early sitting readiness. The Gross Motor Function Measure (GMFM) Sitting Dimension was used to assess sitting capacity, and a 5-min free play observation was used to assess sitting performance.

RESULTS

Both capacity and performance increased at a faster rate initially, with more deceleration across time, in infants with typical development compared to infants with motor delay. At lower GMFM scores, changes in GMFM sitting were associated with larger changes in independent sitting for infants with typical development, and the association between GMFM sitting and independent sitting varied more across GMFM scores for typically developing infants.

CONCLUSIONS

Intervention and assessment for infants with motor delay should target both sitting capacity and sitting performance.

A systematic synthesis of qualitative studies on parents' experiences of participating in early intervention programs with their infant born preterm

Early intervention programs involving both the parent and the infant born preterm have demonstrated positive effects on developmental outcomes for the children. However, studies have also shown that parental engagement and adherence when implementing intervention programs can be challenging. The aim of this review was to provide a comprehensive description and new insights into key messages gleaned from the parent reports on participating in early intervention with their infant born preterm; knowledge vital to facilitate implementation of early interventions into clinical practice when using a model of direct parent involvement. Early intervention is broadly defined as a multi-interdisciplinary field provided to children from birth to five years of age to foster child health, wellbeing, development, adapting parenting and family function. For this systematic synthesis we define early intervention as programs with specific activities completed with the infant during the first year after birth. We assembled qualitative interview studies on parents' experiences with participation in early intervention and applied Malterud's qualitative systematic meta-synthesis to synthesize and translate the original findings across studies. In the analysis we applied enactive concepts of embodiment, autonomy, participatory sensemaking, and agency. 10 qualitative studies were identified and included. The systematic synthesis reveals how parents' successful and meaningful participation in early intervention programs were facilitated by their "active embodied doing." The "embodied doing" appeared as the basis for the parents' sense-making processes, development of confidence, and the ability for parents to see new possibilities for actions within themselves, with and in the child. In that respect, a perception of mutuality in the interaction between parent, infant and interventionist was central. Consequently, an important consideration when implementing early intervention into clinical practice is to promote embodied parent-infant interactions as well as trust between the parent and the interventionist.

Parent-child interactions in early life mediating association between prenatal maternal stress and autistic-like behaviors among preschoolers

A range of studies have shown that prenatal maternal stress (PNMS) exposure is associated with offspring autistic-like behaviors, however the potential pathways remain unexplored. This study aimed to evaluate the mediating role of parent-child interactions in early life in the association between PNMS exposure and preschoolers' autistic-like behaviors. Data from 65,928 child-parent dyads were obtained via a primary caregiver-reported questionnaire administered as part of the Longhua Child Cohort Study. To strengthen confidence in the reliability of the results, the analyses were initially conducted on a random selection of 70% of the total sample, and then validated on the remaining 30% of the sample. Analysis of covariance and multiple linear models were employed to estimate the associations between PNMS exposure, parent-child interactions in early life, and children's autistic-like behaviors. The results showed that PNMS exposure was positively associated with the presence of autistic-like behaviors at preschool age. The total indirect effect of the frequency of positive parent-child interactions in early life accounted for 9.69% or 8.99% of the variance of the association. Our findings indicate that parent-child interactions in early life might function as potential mediators of the association between PNMS and the increased risk of offspring autistic-like behaviors.

Infant-Directed Speech to 3-Month-Old Severe Preterm Infants: The Influence of Birth Weight and Maternal Depressive Symptoms

Severe premature birth (<32 weeks) is a risk factor for the development of maternal perinatal depression, while also affecting dyadic interactions and child outcomes. Although several studies have examined the impacts of prematurity and depression on early interactions, only a few studies have investigated the features of maternal verbal input. Furthermore, no study has investigated the relationship between the effect of severity of prematurity according to birth weight and maternal input. This study aimed to explore the effects of the severity of preterm birth and postnatal depression on maternal input during early interactions. The study included 64 mother-infant dyads, classified into three groups: 17 extremely low birth weight (ELBW) preterm infants, 17 very low birth weight (VLBW) preterm infants, and 30 full-term (FT) infants. At 3 months postpartum (corrected age for preterm infants), the dyads participated in a 5-min free interaction session. Maternal input was analyzed using the CHILDES system in terms of lexical and syntactic complexity (i.e., word types, word tokens, mean length of the utterance) and functional features. Maternal postnatal depression (MPD) was assessed using the Edinburgh Postnatal Depression Scale. The results showed that in high-risk conditions (i.e., ELBW preterm birth and maternal postnatal depression), maternal input was characterized by a lower frequency of affect-salient speech and a higher proportion of information-salient speech, specifically as directives and questions, suggesting that mothers in these conditions may experience more difficulty in conveying affective content to their infants. Moreover, the more frequent use of questions may reflect an interactive style characterized by a higher level of intrusiveness. These findings provide preliminary evidence of the impacts of prematurity severity and maternal depression on maternal verbal input, highlighting the importance of assessing both factors in clinical practice. Understanding the mechanisms underlying the impacts of prematurity and depression on early interactions may inform the development of tailored interventions aimed at promoting positive parent-infant interactions and child development.

Separation in Unity: Dialogical Transformation of Maternal Bond

The objective of this paper is to explore mothers' psychological adaptation related to separation from their newborn children immediately after birth. Mother and child separation has traditionally received attention from the child's perspective, but given that the bond is dyadic, the mother's wellbeing should also be considered. This qualitative study is based on interview data with mothers of premature infants. From the analysis, three themes emerged: concerns during pregnancy about premature birth; emotional strain caused by separation; and the need to protect and to be close to the newborn. Drawing on the perspectives of dialogical self theory and semiotic regulation model, the paper will focus on intra-psychological dynamics and will analyze the adaptation process in terms of I-positions. Based on the analysis, the maternal bond represents the integration of the I-position I-as-mother and My child, which is integrated during the pregnancy into the core of the self. It can be assumed that rupture of the self-continuity is activated by the birth of the child, which is then compounded if the child leaves. The maternal superordinate viewpoint (meta-I-position) directs a woman's behavior and allows for a sense of coherence under dynamic organization related to the birth of the child. The potential for psychological adaptation is presented as an ability to establish self-continuity.

Examining the impact of premature birth on parental mental health and family functioning in the years following hospital discharge: A review

BACKGROUND

This review provides an update of the current research related to the impact of extreme and very premature birth on parental mental health and family functioning following discharge from hospital.

METHODS

Full-text peer reviewed articles in English, describing parents' and families' health and wellbeing after the discharge from hospital of their baby using validated questionnaires, were evaluated. Results of included studies are presented in a summarized format. Embase, Medline and PsycINFO databases were accessed in January 2021.

RESULTS

38 studies were included. Nine manuscripts reported on parental mental health and 13 on stress, which are a concern after the birth of a premature infant, especially in the first year. Depression, anxiety, and stress are known to measure higher compared to parents of infants born at term. Over several years, these measures of mental health decrease significantly. Four reported on quality of life for parents of premature infants, which is reduced immediately after discharge, but then improves over time. The impact of premature birth on the family functioning was described in ten included studies and was described to have positive and negative consequences.

CONCLUSION

The negative impact of the premature birth and hospital journey on parental mental health lessens significantly with time.

Childbirth-related post-traumatic stress disorder symptoms and mother-infant neurophysiological and behavioral co-regulation during dyadic interaction: study protocol

BACKGROUND

Mother's childbirth-related posttraumatic stress disorder (PTSD) symptoms have a negative impact on mother and infant's behaviors during dyadic interactions which may increase mother-infant neurophysiological and behavioral co-regulation difficulties, leading to dysregulated mother-infant interactions. This study was specifically designed to analyze: (1) the sociodemographic and obstetric factors associated with mother's childbirth-related PTSD symptoms; (2) mother-infant neurophysiological functioning and behavioral co-regulation during dyadic interaction; (3) the impact of mother's childbirth-related PTSD symptoms on neurophysiological and behavioral mother-infant co-regulation during dyadic interaction; (4) the moderator role of previous trauma on the impact of mother's childbirth-related PTSD symptoms on neurophysiological and behavioral mother-infant co-regulation during dyadic interaction; and (5) the moderator role of comorbid symptoms of anxiety and depression on the impact of mother's childbirth-related PTSD symptoms on neurophysiological and behavioral mother-infant co-regulation during dyadic interaction.

METHODS

At least 250 mothers will be contacted in order to account for refusals and dropouts and guarantee at least 100 participating mother-infant dyads with all the assessment waves completed. The study has a longitudinal design with three assessment waves: (1) 1-3 days postpartum, (2) 8 weeks postpartum, and (3) 22 weeks postpartum. Between 1 and 3 days postpartum, mothers will report on-site on their sociodemographic and obstetric characteristics. At 8 weeks postpartum, mothers will complete online self-reported measures of birth trauma, previous trauma, childbirth-related PTSD, anxiety, and depressive symptoms. At 22 weeks postpartum, mothers will complete online self-reported measures of childbirth-related PTSD, anxiety, and depressive symptoms. Mothers and infants will then be home-visited to observe and record their neurophysiological, neuroimaging and behavioral data during dyadic interactions using the Still-face Paradigm. Activation patterns in the prefrontal cortices of mother and infant will be recorded simultaneously using hyperscanning acquisition devices. Unadjusted and adjusted multilevel linear regression models will be performed to analyze objectives 1 to 3. Moderation models will be performed to analyze objectives 4 and 5.

DISCUSSION

Data from this study will inform psychological interventions targeting mother-infant interaction, co-regulation, and infant development. Moreover, these results can contribute to designing effective screenings to identify mothers at risk of perinatal mental health problems and those who may need specialized perinatal mental health care.

Prelinguistic intersubjective and socio-communicative skills in infants with neurodevelopmental disabilities aged 0-36 months: A new assessment and parent support tool

Background

Although children with neurodevelopmental disability (NDD) present with several deficits, they partially share developmental impairments in prelinguistic intersubjective and socio-communicative skills, which are not easily assessed by conventional tests during the first years of life.

Aim

The current paper presents a new procedure to assess the prelinguistic intersubjective and socio-communicative skills of NDD children aged 0-36 months. A specific observation form template, called the Observation of Prelinguistic Intersubjective and Socio-Communicative Skills (OPISCoS) form, has been designed to systematically detect infant skills during daily routines (e.g., mealtime, playtime, desk activities). The OPISCoS form helps speech therapists to provide parents support to better perceive and understand early communicative signals from their children, avoiding the risk of excessive or reduced social stimulation.

Methods

The OPISCoS form is composed of three sections, namely, "Pragmatics and Communication," "Decoding," and "Expression," which are useful to delineate the communication abilities of children with NDD and are not tapped by traditional batteries. Vignettes from clinical practice illustrate and provide exemplifications for using the OPISCoS form with NDD infants and their parents.

Results

The OPISCoS form was reported for two children and showed potential in detecting disrupted communicative behaviors and planning specific early interventions. Further, we observed an improvement not only in children's communicative abilities improve but also in their interactions with parents. From a clinical point of view, the OPISCoS form (1) offers an observational perspective of prelinguistic intersubjective and socio-communicative skills in infants with NDD and (2) may be useful to practitioners to enhance parents' sensitivity to their infants' communicative behavior.

Conclusion

The OPISCoS form was developed in clinical practice and is based on a very preliminary description of a new observational procedure as integration for the assessment of NDD children. The OPISCoS form appears to be a useful tool for the clinical assessment of prelinguistic intersubjective and socio-communicative skills in NDD infants as well as for promoting the quality of early parenting.

Childbirth related PTSD and its association with infant outcome: A systematic review

INTRODUCTION

Maternal postnatal mental health problems may negatively impact child development. Postpartum research has mainly focused on the impact of maternal depression and anxiety due to their high prevalence (13-25 % and 10-18 %, respectively). However, maternal childbirth-related PTSD (CB-PTSD) could be another important risk factor in child development (estimated prevalence: 4.7 %).

OBJECTIVE

We investigated whether maternal CB-PTSD (symptoms) are associated with a negative mother-child relationship and/or child developmental outcome for children aged 0-5 years. Furthermore, we examined whether maternal trauma-focused therapy can positively impact mother and child outcomes.

METHODS

We performed a systematic review by searching three databases (Embase, Medline, PsycInfo). Search terms involved: 'birth or delivery modes', 'PTSD psychological trauma', and 'child development or child behavior'. Two independent reviewers evaluated all eligible papers.

RESULTS

Thirty-five papers (30 samples) were included and qualitatively reported. Results suggest a negative association of maternal CB-PTSD (symptoms) with mother-infant attachment and child behavior. However, confounding factors may explain this association. The evidence on associations with breastfeeding, sleeping, socio-emotional development, and weight gain is insufficient. Research investigating the effect of maternal trauma-focused therapy on a child's outcome is scarce, contradictory, and of low quality.

CONCLUSION

This systematic review suggests that maternal CB-PTSD may be associated with an increased number of problems in mother-infant attachment and child behavior, but other domains remain scarcely investigated and methodologic issues are present (cross-sectional study design, influence of confounding variables, sample representativeness, diversity in assessment tools). Our results support a multidisciplinary approach to providing early prevention and screening of the maternal mental health state.

Skin-to-skin SDF positioning: The key to intersubjective intimacy between mother and very preterm newborn-A pilot matched-pair case-control study

Background

Skin-to-skin contact (SSC) has been widely studied in NICU and several meta-analyses have looked at its benefits, for both the baby and the parent. However, very few studies have investigated SSC' benefits for communication, in particular in the very-preterm newborn immediately after birth.

Aims

To investigate the immediate benefits of Supported Diagonal Flexion (SDF) positioning during SSC on the quality of mother-very-preterm newborn communication and to examine the coordination of the timing of communicative behaviors, just a few days after birth.

Subjects and study design

Monocentric prospective matched-pair case-control study. Thirty-four mothers and their very preterm infants (27 to 31 + 6 weeks GA, mean age at birth: 30 weeks GA) were assigned to one of the two SSC positioning, either the Vertical Control positioning (n = 17) or the SDF Intervention positioning (n = 17). Mother and newborn were filmed during the first 5 min of their first SSC.

Outcome measures

Infants' states of consciousness according to the Assessment of Preterm Infants' Behavior scale (APIB). Onset and duration of newborns' and mothers' vocalizations and their temporal proximity within a 1-s time-window.

Results

In comparison with the Vertical group, very preterm newborns in the SDF Intervention Group spent less time in a drowsy state and more in deep sleep. At 3.5 days of life, newborns' vocal production in SSC did not differ significantly between the two groups. Mothers offered a denser vocal envelope in the SDF group than in the Vertical group and their vocalizations were on average significantly longer. Moreover, in a one-second time-frame, temporal proximity of mother-very preterm newborn behaviors was greater in the SDF Intervention Group.

Conclusion

Although conducted on a limited number of dyads, our study shows that SDF positioning fosters mother-very preterm newborn intimate encounter during the very first skin to skin contact after delivery. Our pioneer data sheds light on the way a mother and her very preterm vocally meet, and constitutes a pilot step in the exploration of innate intersubjectivity in the context of very preterm birth.

Parental priorities in the home care of preterm and full term newborns

BACKGROUND

The initial weeks after hospital discharge is a period of adaptation when parents assume great responsibility for the care of their child. Preterm birth may impact their demands of care.

AIMS

To compare parental priorities in the care of preterm and full-term newborns in the first two months after hospital discharge and to identify changes in priorities over time.

METHODS

Parents of 22 full-term and 19 preterm infants were followed for two months after hospital discharge, with three timepoint evaluations of the parental priorities. They reported on infant care demands in a semi-structured interview.

RESULTS

Despite prematurity, demands were similar between groups. Within-group changes occurred over time. Priorities related to bathing and caring for the navel showed significant reduction (p < 0.01); demands related to children's health care increased in the groups (p < 0.01). Feeding and sleep priorities were reduced in the full-term group (p < 0.02). Children's adaptation to routine increased significantly in the preterm group (p = 0.04).

CONCLUSION

Knowledge of parents' priorities in caring for preterm or full-term newborns at home helps health care teams develop appropriate support strategies and improve specialized assistance to the families.

Impact of COVID-19 lockdown on maternal psychological status, the couple's relationship and mother-child interaction: a prospective study

BACKGROUND

To compare the rate of postpartum depression (PPD) during the first COVID-19 lockdown with the rate observed prior to the pandemic, and to examine factors associated with PPD.

METHODS

This was a prospective study. Women who gave birth during the first COVID-19 lockdown (spring 2020) were offered call-interviews at 10 days and 6-8 weeks postpartum to assess PPD using the Edinburgh Postnatal Depression Scale (EPDS). Post-traumatic symptoms (Perinatal Post-traumatic Stress Disorder Questionnaire, PPQ), couple adjustment, and interaction and mother-to-infant bonding were also evaluated. The observed PPD rate was compared to the one reported before the pandemic. Factors associated with an increased risk of PPD were studied. The main outcome measures were comparison of the observed PPD rate (EPDS score > 12) to pre-pandemic rate.

RESULTS

Of the 164 women included, 27 (16.5% [95%CI: 11.14-23.04]) presented an EPDS score > 12 either at 10 days or 6-8 weeks postpartum. This rate was similar to the one of 15% reported prior to the pandemic (p = 0.6). Combined EPDS> 12 or PPQ > 6 scores were observed in 20.7% of the mothers [95%CI: 14.8-0.28]. Maternal hypertension/preeclampsia (p = 0.007), emergency cesarean section (p = 0.03), and neonatal complications (p = 0.008) were significantly associated with an EPDS> 12 both in univariate and multivariate analysis (OR = 10 [95%CI: 1.5-68.7], OR = 4.09[95%CI: 1.2-14], OR = 4.02[95%CI: 1.4-11.6], respectively).

CONCLUSIONS

The rate of major PPD in our population did not increase during the first lockdown period. However, 20.7% of the women presented with post-traumatic/depressive symptoms.

Mental health impact on Black, Asian and Minority Ethnic populations with preterm birth: A systematic review and meta-analysis

BACKGROUND

Preterm birth (PTB) is one of the main causes of neonatal deaths globally, with approximately 15 million infants are born preterm. Women from the Black, Asian, and Minority Ethnic (BAME) populations maybe at higher risk of PTB, therefore, the mental health impact on mothers experiencing a PTB is particularly important, within the BAME populations.

AIM

To determine the prevalence of mental health conditions among BAME women with PTB as well as the methods of mental health assessments used to characterise the mental health outcomes.

METHODS

A systematic methodology was developed and published as a protocol in PROSPERO (CRD42020210863). Multiple databases were used to extract relevant data. I² and Egger’s tests were used to detect the heterogeneity and publication bias. A trim and fill method was used to demonstrate the influence of publication bias and the credibility of conclusions.

RESULTS

Thirty-nine studies met the eligibility criteria from a possible 3526. The prevalence rates of depression among PTB-BAME mothers were significantly higher than full-term mothers with a standardized mean difference of 1.5 and a 95% confidence interval (CI) 29%-74%. The subgroup analysis indicated depressive symptoms to be time sensitive. Women within the very PTB category demonstrated a significantly higher prevalence of depression than those categorised as non-very PTB. The prevalence rates of anxiety and stress among PTB-BAME mothers were significantly higher than in full-term mothers (odds ratio of 88% and 60% with a CI of 42%-149% and 24%-106%, respectively).

CONCLUSION

BAME women with PTB suffer with mental health conditions. Many studies did not report on specific mental health outcomes for BAME populations. Therefore, the impact of PTB is not accurately represented in this population, and thus could negatively influence the quality of maternity services they receive.

The Joint Observation in Neonatology and Neurodevelopmental Outcome of Preterm Infants at Six Months Corrected Age: Secondary Outcome Data from a Randomised Controlled Trial

This study aimed to evaluate the impact of a standardised joint observation (JOIN) performed in the neonatal intensive care unit (NICU) on the neurodevelopment of preterm infants at six months corrected age (CA) compared with a preterm control group. In this monocentric interventional randomised controlled trial, we allocated 76 mothers and their preterm neonates to either JOIN, an early one-session intervention, or standard care during the NICU hospitalisation. The neurodevelopment of the preterm infants was assessed by standardised developmental tests at six months CA and compared between the intervention and the control groups. This randomised controlled trial was registered on clinicaltrials.gov (NCT02736136) in April 2016. Sixty-five infants underwent neurodevelopmental assessment at six months CA. There were no significant differences between the two groups in neurodevelopmental outcome measures. The JOIN intervention was not associated with significant improvement in neurodevelopment at six months CA in preterm infants.

Parental Distress and Affective Perception of Hospital Environment after a Pictorial Intervention in a Neonatal Intensive Care Unit

Pictorial humanization is a useful intervention for the improvement of hospitalized patients’ affective states. Despite benefits in many hospital wards having been well documented, so far, no attention was paid to the Neonatal Intensive Care Unit (NICU). The aim of the present study was to evaluate the levels of distress and the affective perception of the environment experienced by parents of infants hospitalized in a NICU after the implementation of an intervention of pictorial humanization. A sample of 48 parents was recruited, 25 before the intervention was performed (Control Group), and 23 after its implementation (Pictorial Humanization Group). All parents completed the “Rapid Stress Assessment Scale” and “Scales of the Affective Quality Attributed to Place” questionnaires. Despite results showing no significant differences on parental distress, after implementation of pictorial intervention parents reported a perception of the NICU as significantly more pleasant, exciting, and arousing, and less distressing, unpleasant, gloomy, and sleepy. A higher level of distress and a perception of the environment as less relaxing was predicted for the Control Group condition. The present study suggests that the pictorial intervention represents a useful technique to create more welcoming hospital environments and to reduce the negative effects associated with infant hospitalization.

Co-regulation and parenting stress over time in full-term, very low birthweight preterm, and psycho-socially at-risk infant-mother dyads: Implications for fostering the development of healthy relationships

From birth, mothers and infants co-regulate their interactions that are shaped by their socio-emotional development, relationship history, current circumstances, and goals. However, few studies have longitudinally explored co-regulation in the context of medical and psycho-social risk. The present 4-wave longitudinal study sought to shed light on factors associated with co-regulation over time in infants from 6- to 48-months. The objectives were to 1) identify differences in co-regulation among low- and at-risk infant-mother dyads, 2) explore changes in co-regulation over time, and 3) explore the associations between infant-mother co-regulation and parenting stress in these low- and at-risk groups over time. Participants included three groups of infant-mother dyads (full-term [FT], n = 48; very low birthweight/preterm [VLBW/preterm] born 26-32 weeks, weighing 800-1500 g, n = 61; psycho-socially at-risk where parents had histories of socioeconomic disadvantage, n = 54) followed longitudinally at 6-, 12-, 18-, and 48-months of age. Dyads engaged in a free play in their homes that was coded for co-regulation using Fogel, de Koeyer, Secrist, Sipherd, Hafen, and Fricke's (2003) Revised Relational Coding System (RRCS), and mothers reported on their level of parenting stress. Results from MANOVAs at each time point indicated significant differences between the groups at 18-months, with psycho-socially at-risk dyads engaging in more one-sided interactions than FT and VLBW/preterm dyads, and more dysregulation and miscommunication than VLBW/preterm dyads. Multi-level models of co-regulation revealed that dyads became progressively less synchronous from 6- to 12-months, followed by greater synchrony and mutual reciprocity from 12-months onwards. Parenting stress was associated with less synchrony and less mutual reciprocity amongst the at-risk groups. Maternal education was associated with greater engagement and girls tended to engage in more synchronous interactions than boys. Our results underscore the value and implications of considering background risk and concurrent parent perceptions in the development and reciprocity of parent-infant co-regulation and their subsequent relationships from infancy onwards.

Early Physiotherapy Intervention Program for Preterm Infants and Parents: A Randomized, Single-Blind Clinical Trial

Background: The early developmental interventions might be designed with a preventative approach to improving the development of at-risk preterm infants. The present study aimed to evaluate the effectiveness of an early physiotherapy intervention on preterm infants’ motor and global development, and on parents’ stress index. Methods: 48 infants were enrolled and randomized into two groups. Infants allocated to the intervention group received an early physiotherapy intervention, based on parental education sessions and tactile and kinesthetic stimulation during the NICU period, as well as a home-based activity program. The intervention commenced after 32 weeks post-menstrual age and ended at 2 months corrected age. Infants allocated to the control group received the usual care based on the NIDCAP-care. Results: No differences were found between groups on the Alberta Infant Motor Scale at 2- or 8-months corrected age. Infants in the intervention group showed more optimal fine motor, problem-solving, personal-social, and communication development at 1 month corrected age. Conclusions: The results showed no effect on the early physiotherapy intervention. Results might be related to the dose or intensity of the intervention, but also to the poor parental compliance. ClinicalTrials.gov NCT03313427.

Experiences of Malawian Mothers During Their Infants' Hospitalization

BACKGROUND

Hospitalization of a newborn infant is stressful for all mothers. Hospitals in Malawi have limited nursing staff and support, so mothers are the primary care providers for their hospitalized infants. Few studies have explored the experience of these mothers as both care providers and mothers.

PURPOSE

The purpose of this study was to explore the experiences of mothers during the hospitalization of the infant. The goal was to increase knowledge of their primary concerns about the hospital stay.

METHODS

This was a descriptive qualitative study conducted at Queen Elizabeth Central Hospital in Malawi. Mothers were interviewed prior to their infant's discharge. We used the directed content analysis approach to analyze our data.

RESULTS

Twenty mothers of preterm or full-term infants were interviewed. The primary concerns were perinatal experiences, the infant's condition and care including breastfeeding, support from family members, and support and care from healthcare providers. Additionally, mothers of preterm infants were concerned about the burdens of kangaroo mother care.

IMPLICATION FOR PRACTICE

In hospitals that provide limited nursing support to mothers and their infants, it is important to identify a support system for the mother and provide mothers with information on infant care.

IMPLICATIONS FOR RESEARCH

Future research should identify specific supports and resources in the community and hospital settings that are associated with positive hospital experiences.

Short-term Music Therapy for Families With Preterm Infants: A Randomized Trial

OBJECTIVES

To evaluate short-term effects of music therapy (MT) for premature infants and their caregivers on mother-infant bonding, parental anxiety, and maternal depression.

METHODS

Parallel, pragmatic, randomized controlled-trial conducted in 7 level III NICUs and 1 level IV NICU in 5 countries enrolling premature infants (<35 weeks gestational age at birth) and their parents. MT included 3 sessions per week with parent-led, infant-directed singing supported by a music therapist. Primary outcome was mother-infant bonding as measured by the Postpartum Bonding Questionnaire (PBQ) at discharge from NICU. Secondary outcomes were parents' symptoms of anxiety measured by General Anxiety Disorder-7 (GAD-7) and maternal depression measured by Edinburgh Postpartum Depression Scale (EPDS). Group differences at the assessment timepoint of discharge from hospital were tested by linear mixed effect models (ANCOVA).

RESULTS

From August 2018 to April 2020, 213 families were enrolled in the study, of whom 108 were randomly assigned to standard care and 105 to MT. Of the participants, 208 of 213 (98%) completed treatment and assessments. Participants in the MT group received a mean (SD) of 10 sessions (5.95), and 87 of 105 participants (83%) received the minimum of 6 sessions. The estimated group effect (95% confidence interval) for PBQ was -0.61 (-1.82 to 0.59). No significant differences between groups were found (P = .32). No significant effects for secondary outcomes or subgroups were found.

CONCLUSIONS

Parent-led, infant-directed singing supported by a music therapist resulted in no significant differences between groups in mother-infant bonding, parental anxiety, or maternal depression at discharge.

Maternal Postpartum Emotional Distress and Preterm Social Withdrawal in the Bedouin Culture

This study aimed to test a serial mediation model proposing that prematurity would be related to changes in maternal emotional distress, which in turn would be related to the mother-child (M-C) interaction, which would ultimately be related to infant social withdrawal. Bedouin mothers and their preterm (n = 48) and full-term (n = 57) infants participated in this study. Mothers' mean age was 27.67 years. In addition, 39.4% of the mothers were primiparas and 60.6% were multiparas. Infants and their mothers were recruited shortly after birth (T1) in the maternity ward or Neonatal Intensive Care Unit (NICU) at Soroka Medical Center and were followed up at ages 6 months (T2) and 12 months (T3). Findings indicated that HIGHER levels of maternal emotional distress during the second half of the first year postpartum and LOWER levels of mother-child interaction, were associated with HIGHER levels of infant social withdrawal at T3. Furthermore, the overall indirect effect suggested that HIGHER levels of maternal nonhostility was a main variable mediating the link between prematurity and LOW levels of infant social withdrawal. Our findings provide evidence that changes in maternal emotional distress during the first year are related to lower infant social withdrawal. Moreover, mothers of premature infants showed higher levels of nonhostility when interacting with their premature infants. These findings highlight the importance of gaining a better understanding of maternal behaviors. Specifically, our study provides important information for researchers and clinicians on a possible mechanism leading to early socioemotional difficulties of premature infants.

Parental Reflective Functioning as a Moderator of the Link Between Prematurity and Parental Stress

We examined group differences between parents, both mothers and fathers, of premature and full-term infants to determine whether they differed in their reports of subjective parenting stress and in their level of parental reflective functioning (PRF). We also tested whether each parent's reflective functioning moderated the links between birth status (prematurity vs. full-term) and parenting stress. A sample of 73 cohabiting, heterosexual Israeli families with a premature (28-36th week gestational age, N = 34) or full-term infant (37th week and above gestational age, N = 39) participated, comprising the two parents' groups. Infants' age averaged 7.07 months (SD = 1.28). Each parent completed the Parent Stress Inventory (PSI) individually to determine his/her subjective personal and childrearing stress levels. The Parent Development Interview (PDI-R2-S) was used to obtain each parent's PRF (self and child/relation-focused) level. Findings showed that the premature and full-term parents did not differ in their PSI scores or PRF levels. However, mothers' self-focused PRF moderated the link between prematurity and personal parenting stress, whereas fathers' self-focused PRF moderated the link between prematurity and childrearing parenting stress. Furthermore, fathers' and mothers' PRF operated differently in the premature and full-term parents' groups. The findings highlight the importance of mothers' and fathers' PRF in predicting parents' subjective stress in general and particularly in the case of infant prematurity. We discuss these findings and their relevance for preventive and therapeutic perinatal interventions.

Measuring Parental Presence in the Neonatal Intensive Care Unit

Parental presence is believed to improve outcomes for infants hospitalized in the neonatal intensive care unit (NICU). As a result, NICU policies and procedures have evolved to support parental presence, and a growing number of studies examine the role of parental presence in the NICU. However, the measurement of parental presence is not standardized, complicating assessment of its impact on child and parent outcomes across studies. We reviewed 29 studies that presented 27 distinct methods of quantifying parental presence in the NICU and reported associations of presence with patient demographics, parental engagement in the NICU, and outcomes for both infants and parents. This overview provides a foundation for standardizing and improving routine measurement of parental presence in the NICU. KEY POINTS: · NICUs encourage visiting ill newborns.. · Measurement of presence is not standardized.. · A uniform method to assess presence is needed..

A Prospective Observational Study to Assess Attachment Representations With Regard to Neurocognitive and Behavioral Outcomes in Children Born Very Prematurely in the Loire Infant Follow-Up Team (LIFT Cohort)

CONTEXT AND PURPOSE

Prematurity is a situation that can disrupt parent-child interactions. We hypothesize that establishing relationships with parents in a context of extreme prematurity can alter the development of secure attachment representations in the child. Furthermore, we hypothesize that secure maternal representations and their possible interactions with prematurity factors prevent the development of insecure or disorganized attachment in the child. In addition, maternal representations and their possible interactions with factors related to prematurity may prevent or accentuate the development of an insecure or disorganized attachment in the child.

METHODS AND ANALYSIS

This is a longitudinal, prospective, exploratory, and bi-centric study. Children born in the neonatal intensive care units of Angers or Nantes University Hospitals with a gestational age of up to 28 weeks will be included in the study. The main objective is to describe the attachment representations at 3 and 5 years through the Attachment Story Completion Task scales and to analyze them in regard to the children's neurocognitive and behavioral outcomes as well as maternal attachment and mental health.

ETHICS

The study file received a favorable opinion for the implementation of this research on February 18, 2020 - ID-RCB no. 2019-A03352-55 (File 2-20-007 id6699) 2°HPS. This study has received authorization from the French Data Protection Authority (CNIL) under no. 920229.

DISCUSSION

A better understanding of attachment representations in extreme prematurity and their possible associations with children's neurocognitive and behavioral outcomes as well as maternal attachment and mental health could pave the way for individualized care at an early stage, or even interventions during the neonatal period to improve the outcome of these vulnerable newborns.

Consequences of Prematurity on Cortisol Regulation and Adjustment Difficulties: A 9-Year Longitudinal Study

A preterm birth represents a stressful event having potentially negative long-term consequences. Thirty-three children born preterm (<33 weeks gestational age) and eleven full-term children participated in a nine-year longitudinal study. Perinatal Risk Inventory (PERI) was used at birth to assess the perinatal stress. Salivary cortisol, collected four times a day over two consecutive days, was measured with radioimmunoassay technique at six months and nine years to assess the hypothalamic-pituitary-adrenal (HPA) axis. Mothers reported post-traumatic symptoms on a self-report questionnaire 12 months after their child's birth and children's adjustment problems at 9 years of child age on the Child Behavior Checklist. Results showed a significant difference in cortisol regulation at nine years between preterm and full-term children but no differences in adjustment problems. Whereas biological factors (i.e., PERI, cortisol regulation at six months) explained cortisol at nine years, maternal post-traumatic symptoms were predictive of adjustment problems in their child. In conclusion, very preterm birth has some long-term consequences on the HPA-axis regulation at nine years. Although cortisol regulation is mostly influenced by biological factors, the presence of maternal post-traumatic symptoms predicts the manifestation of adjustment problems in both groups. This shows the importance of maternal psychological well-being for child development. Further research is needed to understand the exact consequences of premature birth on cortisol regulation and the implication for the child's development and health.

The role of maternal interactive behavior and gestational age in predicting infant affect during the Still-Face Paradigm

BACKGROUND

Emotion regulation develops through bidirectional affective communication.

AIM

To investigate the role of maternal interactive behavior in predicting infant affect among preterm versus full-term infants.

STUDY DESIGN

The association between maternal interactive behavior (contingent, attention seeking, watching) and infant affect during a modified Still Face (SF) paradigm in a sample of 22 preterm and 28 full term infants (3 ½ - 4 ½ months old) was investigated.

METHODS

Maternal behavior and infant affect were coded in one second intervals.

RESULTS

Maternal contingent interaction was positively correlated with positive infant affect (p < 0.001 for Play; p < 0.001 for Reunion#1; p < 0.01 for Reunion#2, respectively), with a stronger association during the second reunion for preterm infants (p < 0.001). In the preterm sample but not in the full-term sample, attention seeking maternal interaction at Play (baseline), Reunion#1, and Reunion#2 were all positively correlated with negative infant affect at Still Face#2. Maternal watching was negatively associated with positive infant affect for the full sample for both Reunion episodes (p < 0.05). Full term infants' negative affect increased from baseline to the first SF episode and then plateaued, whereas preterm infants demonstrated greater negative affect and less recovery throughout. Mothers of full-term infants showed increased contingent responding after the first SF stressor, while mothers of preterm infants did not (p < 0.05).

CONCLUSIONS

Preterm infants may be more susceptible to both positive and negative maternal behaviors and mothers of full-term infants may be more responsive to infants' increased distress. Relationship-focused interventions addressing maternal behaviors may enhance positive emotionality and improve self-regulation in medically at-risk infants.

Early Intervention for Preterm Infants and Their Mothers: A Systematic Review

This systematic review evaluates the efficacy of various early interventions on maternal emotional outcomes, mother-infant interaction, and subsequent infant outcomes during neonatal intensive care unit admission and postdischarge. Key interventions associated with outcomes in both the neonatal intensive care unit and postdischarge (ie, home) settings are summarized. A comprehensive search of peer-reviewed randomized controlled trials involving early interventions for infants and their mother published between 1993 and 2013 in the electronic databases PubMed, CINAHL, EMBASE, PsychINFO, and Cochrane was undertaken. Methodological quality was assessed using the PEDro scale to evaluate internal and external validity of the study. Twelve randomized controlled trials were included in the review, and all used some form of parenting education. The interventions had limited effects on maternal stress and mother-infant interaction and positive effects on maternal anxiety, depressive symptoms, and maternal coping. There were positive effects on infants' short-term outcomes for length of stay and breast-feeding rate. Positive and clinically meaningful effects of early interventions were seen in some physiological/psychological outcomes of mothers and preterm infants. It is important for nurses to foster close mother-infant contact and increase maternal competence during and after the infant's hospitalization period.

A self-comfort oriented pattern of regulatory behavior and avoidant attachment are more likely among infants born moderate-to-late preterm

Infants born preterm (<37 gestational weeks, GW) are at increased risk for regulatory difficulties and insecure attachment. However, the association between infants' regulatory behavior patterns and their later attachment organization is understudied in the preterm population. We addressed this gap by utilizing a Portuguese sample of 202 mother-infant dyads. Specifically, we compared the regulatory behavior patterns of 74 infants born moderate-to-late preterm (MLPT, 32-36 GW) to those of 128 infants born full-term (FT, 37-42 GW) and evaluated the associations of these regulatory patterns with later attachment. Infants' regulatory behavior patterns (Social-Positive Oriented, Distressed-Inconsolable, or Self-Comfort Oriented) were evaluated in the Face-to-Face-Still-Face paradigm at 3 months, and their attachment organization (secure, insecure-avoidant, or insecure-ambivalent) was evaluated in the Strange Situation at 12 months corrected age. In both samples, the Social-Positive-Oriented regulatory pattern was associated with secure attachment; the Distressed-Inconsolable pattern with insecure-ambivalent attachment; and the Self-Comfort-Oriented pattern with insecure-avoidant attachment. However, compared to FT infants, infants born MLPT were more likely to exhibit a Self-Comfort-Oriented pattern and avoidant attachment. Most perinatal and demographic variables were not related to infant outcomes. However, infants with a higher 1-min Apgar were more likely to exhibit the Social-Positive-Oriented regulatory pattern and secure attachment.

The preterm infant-parent programme for attachment-PIPPA Study: a randomised controlled trial

BACKGROUND

There is increasing recognition of adverse mental health consequences of preterm birth and the impact on social-emotional development. However, the quality of the developing parent-infant relationship may be protective, with enhanced maternal sensitivity to infants' cues associated with improved outcomes.

METHODS

Eighty mothers and their preterm infants born <32 weeks gestation were randomised to intervention and standard care groups. Intervention comprised reflective interview, observation of infant cues and video interaction guidance (VIG). The primary outcome, maternal sensitivity during play, was measured by the Child Adult Relationship Evaluation-Index. Secondary outcomes were infant social-emotional problems measured by the Ages and Stages Questionnaire-Social-Emotional version.

RESULTS

There was no statistically significant difference between the intervention and standard care groups in maternal sensitivity during play at 9 months corrected age (CA). In the secondary outcome analysis at 12 months CA, infants in the intervention group had fewer self-regulation problems than infants whose mothers received standard care. Per-protocol analysis revealed that infants whose mothers completed VIG had significantly fewer communication problems.

CONCLUSIONS

This early attachment-focussed intervention integrating VIG for mothers and their preterm infants did not enhance maternal sensitivity; however, there were effects on infant social-emotional problems at 12 months CA.

IMPACT

Preterm birth can adversely affect infant and parent mental health and the quality of the parent-infant relationship. Early intervention to support parent-infant interaction can have positive effects on infant social-emotional development. There was no statistically significant difference in maternal sensitivity during play at 9 months CA. However, there were fewer infant self-regulation and communication problems reported by mothers at 12 months CA following intervention. Further evaluations of attachment-focussed interventions in the neonatal intensive care unit are needed.

A Study of Maternal Competence in Preterm Birth Condition, during the Transition from Hospital to Home: An Early Intervention Program's Proposal

The study was conducted with 104 mothers (average age 32.5 years, SD 6.1) of preterm infants (very and moderately preterm but still healthy) to monitor the perceived maternal role competence from the time of hospitalisation to post-discharge, in order to define an intervention program to support mothers during this transition. A targeted Q-Sort tool (Maternal Competence Q-Sort in preterm birth) was applied at two different times as a self-observation tool for parenting competence in neonatology. A tendency towards dysregulation of the maternal role competence was detected, mainly in terms of low self-assessment and was found to worsen during post-discharge, particularly with regard to caregiving ability. This study suggests the importance of accompanying parenting competence in preterm birth conditions, not only during hospitalisation in the Neonatal Intensive Care Unit (NICU) but also following discharge in order to promote the development of premature infants. This paper reports in the last part a specific integrated psychoeducational intervention program (psychologist and nurses), which we defined precisely in light of the suggestions offered by the study data on perceived maternal competence created with the Q-sort.

Longitudinal Study of Music Therapy's Effectiveness for Premature Infants and Their Caregivers (LongSTEP): Feasibility Study With a Norwegian Cohort

Premature infants and their parents experience significant stress during the perinatal period. Music therapy (MT) may support maternal-infant bonding during this critical period, but studies measuring impact across the infant's first year are lacking. This nonrandomized feasibility study used quantitative and qualitative methods within a critical realist perspective to evaluate the feasibility, acceptability, and suitability of the treatment arm of the Longitudinal Study of music Therapy's Effectiveness for Premature infants and their caregivers (LongSTEP) (NCT03564184) trial with a Norwegian cohort (N = 3). Families were offered MT emphasizing parent-led infant-directed singing during neonatal intensive care unit (NICU) hospitalization and across 3 months post-discharge. We used inductive thematic analysis of semi-structured interviews with parents at discharge from NICU and at 3 months and analyzed quantitative variables descriptively. Findings indicate that: (1) parents of premature infants are willing to participate in MT research where parental voice is a main means of musical interaction; (2) parents are generally willing to engage in MT in NICU and post-discharge phases, finding it particularly interesting to note infant responsiveness and interaction over time; (3) parents seek information about the aims and specific processes involved in MT; (4) the selected self-reports are reasonable to complete; and (5) the Postpartum Bonding Questionnaire appears to be a suitable measure of impaired maternal-infant bonding. Parents reported that they were able to transfer resources honed during MT to parent-infant interactions outside MT and recognized parental voice as a central means of building relation with their infants. Results inform the implementation of a subsequent multinational trial that will address an important gap in knowledge.

Emotion regulation from infancy to toddlerhood: Individual and group trajectories of full-term and very-low-birthweight preterm infants

Adaptive emotion regulation begins with infants operating jointly with their parents to regulate their emotions, which fosters the development of independent regulation. Little is known about when or how this transition occurs, or the impact of factors such as parental availability or premature birth status. The current study examined the use of self-soothing, attentional distraction, and dyadic regulation in full-term and healthy very-low-birthweight (VLBW) preterm infant-mother dyads at 5 ½, 12, and 18 months of age. At 5 ½ months, dyads participated in the Still-Face procedure. At 12 and 18 months, dyads participated in two free-play interactions, a puzzle task, and an interference task. Emotion regulation behaviors were coded using two systematic, observational systems. Results indicated that infants used less self-soothing and attentional distraction and more dyadic regulation as they aged. Increased use of self-soothing at earlier ages predicted increased use of dyadic regulation at subsequent ages. Toddlers used more independent, attention-seeking, and escape behavior during periods of maternal unavailability. There were no significant differences between full-term and VLBW/preterm toddlers' emotion regulation behaviors. Results from the current study contribute to the understanding of normative development of emotion regulation and the risk associated with prematurity.

Patterns of regulatory behavior in the still-face paradigm at 3 months: A comparison of Brazilian and Portuguese infants

Three infant regulatory behavior patterns have been identified during the Face-to-Face Still-Face paradigm (FFSF) in prior research samples: a Social-Positive Oriented pattern (i.e., infants exhibit predominantly positive social engagement), a Distressed-Inconsolable pattern (i.e., infants display conspicuous negative affect that persists or increases across FFSF episodes), and a Self-Comfort Oriented pattern (e.g., infants primarily engage in self-comforting behaviors such as thumb-sucking). However, few studies have examined these patterns outside US and European countries or evaluated potential cross-country differences in these patterns. In this study, we compared the regulatory behavior patterns of 74 Brazilian and 124 Portuguese infants in the FFSF at 3 months of age, and evaluated their links to demographic and birth variables. The prevalence of the three regulatory patterns varied by country. The most frequent pattern in the Portuguese sample was the Social-Positive Oriented, followed by the Distressed-Inconsolable and the Self-Comfort Oriented. However, in the Brazilian sample, the Distressed-Inconsolable pattern was the most prevalent, followed by the Social-Positive Oriented and the Self-Comfort Oriented. Moreover, in the Brazilian sample, familial SES was higher among infants with a Social-Positive pattern whereas 1^st-minute Apgar scores were lower among Portuguese infants with a Distressed-Inconsolable Oriented pattern of regulatory behavior. In each sample, Social Positive pattern of regulatory behavior was associated with maternal sensitivity, Self-Comfort Oriented pattern of regulatory behavior with maternal control, and Distressed-Inconsolable pattern with maternal unresponsivity.

Family-centered music therapy-Empowering premature infants and their primary caregivers through music: Results of a pilot study

BACKGROUND

In Neonatal Intensive Care Units (NICUs) premature infants are exposed to various acoustic, environmental and emotional stressors which have a negative impact on their development and the mental health of their parents. Family-centred music therapy bears the potential to positively influence these stressors. The few existing studies indicate that interactive live-improvised music therapy interventions both reduce parental stress factors and support preterm infants' development.

METHODS

The present randomized controlled longitudinal study (RCT) with very low and extremely low birth weight infants (born <30+0 weeks of gestation) and their parents analyzed the influence of music therapy on both the physiological development of premature infants and parental stress factors. In addition, possible interrelations between infant development and parental stress were explored. 65 parent-infant-pairs were enrolled in the study. The treatment group received music therapy twice a week from the 21st day of life till discharge from hospital. The control group received treatment as usual.

RESULTS

Compared to the control group, infants in the treatment group showed a 11.1 days shortening of caffeine therapy, 12.1 days shortening of nasogastric/ orogastric tube feed and 15.5 days shortening of hospitalization, on average. While these differences were not statistically significant, a factor-analytical compound measure of all three therapy durations was. From pre-to-post-intervention, parents showed a significant reduction in stress factors. However, there were no differences between control and treatment group. A regression analysis showed links between parental stress factors and physiological development of the infants.

CONCLUSION

This pilot study suggests that a live-improvised interactive music therapy intervention for extremely and very preterm infants and their parents may have a beneficial effect on the therapy duration needed for premature infants before discharge from hospital is possible. The study identified components of the original physiological variables of the infants as appropriate endpoints and suggested a slight change in study design to capture possible effects of music therapy on infants' development as well. Further studies should assess both short-term and long-term effects on premature infants as well as on maternal and paternal health outcomes, to determine whether a family-centered music therapy, actually experienced as an added value to developmental care, should be part of routine care at the NICU.

Social cognition following preterm birth: A systematic review

Social cognitive abilities are affected by preterm birth, but pathways to, and risk factors for this outcome are not well mapped. We examined direct assessment tasks including objective coding of parent-child play to chart social development in infancy and pre-school years. A systematic search and data-extraction procedure yielded seventy-nine studies (4930 preterm and 2109 term children, aged birth - five years), for inclusion. We detected a pattern of reduced social attention in the first 12 months of life with evidence of reduced performance in social cognitive tasks later in the preschool years. However, we did not identify a consistent, distinctive preterm social phenotype in early life. Instead, the interactive behaviour of preterm infants reflects factors from outside the social cognitive domain, such as attention, language, and socioeconomic status. By combining data across samples and measures we revealed the role of domain-general skills, which may in future prove fruitful intervention targets.

Chest-to-Back Skin-to-Skin Contact to Regulate Body Temperature for Low Birth Weight and/or Premature Babies: A Crossover Randomized Controlled Clinical Trial

Skin-to-skin contact (SSC) is one of the critical components of kangaroo mother care (KMC), which is an intervention to enhance the survival of low birth weight (LBW) and/or premature infants in low-income settings. Chest-to-chest (CC) contact has been practiced widely; however, mothers face practical challenges to continuously provide CC-SSC. Hence, we assessed the efficacy of chest-to-back (CB) SSC as an alternative to CC-SSC in regulating body temperature for LBW and/or premature babies in Ethiopia. We applied a noninferiority clinical trial among LBW and/or premature infants admitted to a referral hospital neonatal intensive care unit (NICU) in Ethiopia. The study randomized the infants into two crossover arms; arm 1 applied first CB-SSC followed by CC-SSC, and arm 2 applied first CC-SSC followed by CB-SSC. The outcome measure was a change in skin temperature. We used a linear mixed-effect model for analysis. The result showed no statistically significant difference in the mean temperature between the comparison arms. In conclusion, we found that the CB-SSC was not inferior to the CC-SSC in regulating body temperature of the babies. Thus, CB-SSC can be further investigated as an alternative to CC-SSC in the kangaroo care model in low-income settings.
