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

BackgroundThe 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. AimsWe 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 designThis is a longitudinal laboratory study conducted from 3 to 12 months of age (corrected-age in the case of infants born PT). SubjectsThe participants are 213 Portuguese infants (FT = 105; MLPT = 52; VEPT = 56) and their mothers. Outcome measuresMother-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. ResultsSecure 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. ConclusionsOur 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.

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.

Maternal postpartum anxiety and the development of infant attachment: The effect of body sensations on infant attachment

BackgroundKnowledge about the influences of maternal postpartum anxiety disorders (PAD) on infant development is limited. Aim of this present study is to evaluate the influence of PAD on infant attachment. MethodsIn a longitudinal study, self-reported anxiety symptoms of N = 70 mothers (N = 28 with PAD diagnosed according to the DSM-IV, N = 42 controls) were examined in the postpartum period and one year later. Infants' attachment was observed in the Strange Situation Test (SST) at the age of 12–24 months. ResultsResults indicate a strong relationship between PAD and infant attachment: infants of mothers with PAD were significantly more likely to be classified as insecure or disorganized than infants of control mothers. Logistic regression analysis led to a significant model with 76.8 % correct classification of infant attachment dependent on the maternal fear of anxiety associated body sensations (OR = 4.848) in the postpartum period. Including maternal sensitivity and interaction behavior, only maternal intrusiveness was additionally associated with infant attachment (ρ = 0.273, p < .05; OR = 45.021, p = .153). LimitationsParticipants were highly educated. Different anxiety disorders included led to a heterogenous sample. Generalization is diminished. Maternal sensitivity was measured on a global scale, and body tension was self-reported. ConclusionsPAD plays a crucial role in the development of infant attachment. Interaction-focused interventions, helping mothers to decrease intrusiveness, and body-focused interventions, helping mothers to deal with their fear of anxiety symptoms, might be promising pathways to buffer the influence of PAD on infant attachment.

Atypical maternal interaction is associated with elevated levels of hair cortisol in children.

The quality of maternal caregiving is an important factor in the healthy development of a child. One consequence of prolonged insensitive and atypical maternal interaction behavior (e.g., withdrawing from interactions with the child and role-reversal, i.e., the takeover of the parental role or parts of it by the child) in mother-child-dyads can cause alteration of the child's stress response system. Higher salivary cortisol concentrations were reported in infants and toddlers directly after negative interactions with their parents. However, no study to date has examined the association between atypical maternal interaction behavior and hair cortisol concentrations (HCC) in infants. Here, we studied the association of maternal interaction behavior with HCC of the child. Mother-child dyads (N = 112) participated in the longitudinal study My Childhood-Your Childhood. The AMBIANCE scale and its subscales were used to assess atypical maternal interaction behavior during the Strange Situation Procedure. Chronic stress levels in the child were assessed by HCC of 3 cm hair strands at the age of 12 months. Maternal educational level (operationalized in highest education level) served as a control variable. Robust multiple linear regression analyses revealed that role/boundary confusion was associated with HCC, i.e., the higher atypical interaction behavior of the mother the higher the HCC in the children. By measuring hair cortisol in this study, it is possible to determine the average long-term activity of the child's stress response system.Thus, atypical maternal interaction behavior could be a risk factor for persistent stress in children, contributing to a higher risk for negative health outcomes in later life. The results of this study highlight the importance of early intervention programs that focus on the relationship between mother and child.

Cortisol reactivity and negative affect among preterm infants at 12 months during a mother-infant interaction task

The purpose of this study was to investigate correlates of preterm (PT) infant’s cortisol reactivity and the association to infant negative affect, during a mother-infant interaction procedure. Participants included 48 infants born prematurely (gestational age < 37 weeks) and their mothers, assessed when infants were 12 months old corrected for prematurity. The examined variables comprised both neonatal and environmental dimensions including maternal interactive behavior. Infant negative affect and maternal interactive behavior were assessed with a standardized mother-infant interaction task. A baseline infant saliva sample was collected before the interaction began, and a second sample after the interaction episodes ended. Results revealed that decrease of infant’s cortisol concentration was significantly associated with the exposure to more sensitive, and less intrusive maternal behaviors. However, once controlled for neonatal risk, family SES and maternal psychological distress, the associations were rendered non-significant. Although the association between cortisol reactivity and negative affect trended toward significance, maternal intrusiveness was the only significant predictor of observed infant negative affect. Findings suggest the importance of primary relational experiences on PT infants' early regulatory competencies.

Cognitively stimulating maternal language as predictor for vocabulary growth

Maternal interaction behavior, particularly maternal language input, is considered to be one of the key factors for child vocabulary development. Previous studies have shown that a higher quantity and diversity of maternal language input is associated with faster vocabulary development. In the present study, we examined cognitive-verbal stimulation as a specific aspect of maternal input, controlling for other relevant internal child characteristics and external environmental influences. Additionally, we compared the effects of cognitive stimulation on vocabulary development with a standard measurement of maternal language input, such as its quantity, to identify specific the effects of cognitive-verbally stimulating interaction behavior. We used data from the Newborn Cohort Study of the German National Educational Panel Study (N = 1127 families) and conducted latent growth curve modeling to examine the vocabulary growth of children between 3 and 7 years of age. As control variables, we also included maternal education and household income in the analyses as well as the children’s age, gender, and initial vocabulary level when they were 2 years old, their phonological working memory, and whether they were learning another native language other than German. The results indicated that general aspects of maternal input, such as the quantity and length of the utterances of maternal language input for 2‑years-olds, were relevant in the earlier stages of vocabulary development, while cognitive stimulation was an important predictor of growth across the later stages of vocabulary development in 3‑ to 7‑year-olds.

The impact of low birthweight in infant patterns of regulatory behavior, mother-infant quality of interaction, and attachment

It remains unclear whether infants born preterm are more likely to develop an insecure attachment with their mothers. In this study, instead of using gestational age criteria, we observe attachment in infants born with very low birthweight. Although the collinearity between gestational age and birthweight is high, infants born with very low birthweight for their gestational age tend to stay more days in NICU and to have more comorbidities than other infants with the same gestational age. Thus, we wonder about the impact of low gestational birth (per se) in infants' regulatory behavior, the quality of mother-infant interactions, and attachment security. The participants are 71 infants' weight lower than 1599 g of gestational weight (varying between 23 and 34 weeks of gestational) and their mothers. Dyads were observed in free play and during Face to Face Still-Face paradigm with infants at 3 months of corrected age. At 12 months of corrected age, mother-infant attachment was observed during Strange Situation. Results indicate that infants with low/very low gestational birthweight have high levels of insecure attachment (70 %) and non-positive patterns of regulatory behavior (64 %). Maternal and infant interactive behavior is highly associated with infant attachment. In turn, maternal interactive behavior is associated with gestational age, birthweight, and number of days in NICU.

Preliminary longitudinal evidence for stability of maternal behavior and infant stress regulation among infants born preterm at 4 and 9 months during the Still Face paradigm

Stress regulation begins to develop in the first year of life through interactions with caregivers, particularly in the presence of stressors. High quality caregiving, characterized by maternal sensitivity and responsiveness to the infant’s emotional cues, is particularly important in the development of infant stress regulation. The purpose of this study was to assess the longitudinal stability of, and associations between, maternal interactive behavior and infant stress regulation (indexed by positive infant affect and cortisol reactivity) in response to the Still Face paradigm (SF) in a cohort of infants born preterm (< 32 weeks gestation, N = 22) at four months and nine months (adjusted age). The percent of time mothers spent using specific interaction styles (contingent maternal interaction (CMI), attention seeking, and watching) during Play/baseline, Reunion#1, and Reunion#2 SF episodes was calculated To assess infant stress regulation, two indices were obtained at both 4 and 9 months during the SF paradigm: the percent of positive affect displayed over each SF episode (0-100%) and a neuroendocrine stress response score based on salivary cortisol reactivity. We found three non-significant but medium-large effect size differences between 4 and 9 month variables, with more positive findings at 9 months. Regarding stability within the 4 month and 9 month episodes, maternal behavior and positive infant affect were non-significantly but moderately stable, with maternal watching behavior being particularly stable. Positive infant affect stability between Reunion#1 and Reunion#2 at 4 months was significantly greater than positive infant affect stability across these two episodes at 9 months. Regarding stability across 4 and 9 month (same) episodes, CMI and positive infant affect showed modest but non-significant stability across (same) 4 and 9 month episodes. Finally, with positive infant affect at Reunion#2 as the “outcome” of the Still Face, CMI at both 4 month Play and Reunion#1 episodes were significantly correlated with this “outcome.” Further, positive infant affect at Reunion#2 was more strongly correlated with CMI at both Play and Reunion#1 for 4 month old compared with 9 month old infants. Thus, sensitive care appears particularly important for younger infants born preterm, and mothers’ behavior early in a repeated stress exposure paradigm may be particularly important in maintaining positive infant affect and in the development of infants’ stress regulation more generally. Identifying the longer-term effects of early stress on infant stress regulation, and its relationship with maternal interaction, has important implications for understanding trajectories of regulatory patterns and deficits. A greater understanding of these relationships is particularly important given that greater emotion and neuroendocrine stress regulation in infancy have been directly associated with numerous positive outcomes throughout childhood.

Relationships Among Maternal Interactive Behaviors, Preschoolers’ Hot and Cool Executive Function, and Conscience

Objectives: Preschoolers’ conscience refers to a concept revolving around moral emotion, cognition and behavior. This study investigates the relationships among preschoolers’ conscience, hot and cool executive function, and maternal interactive behaviors. Furthermore, it examines the mediating role of preschoolers’ executive function in the relationship between maternal interactive behaviors and preschoolers’ conscience.Methods: Participants comprised 220 mothers and teachers engaging with preschoolers. Data were collected during the COVID-19 period. Therefore, a research process, which suited the changing operations of day-care centers and kindergartens due to social distancing, was adopted. The mothers answered questionnaires on preschoolers’ conscience and maternal interactive behaviors, and the teachers on hot and cool executive function. Obtained data were analyzed using correlations, multiple regression, hierarchical regression, and bootstrapping.Results: Results revealed that the preschoolers’ conscience was significantly related to maternal interactive behaviors and preschoolers’ hot and cool executive function. The preschoolers’ executive function mediated the effect of maternal interactive behaviors on their conscience. Specifically, the plannning and organizing of the executive function fully mediated the relationship between maternal efficient interactive behaviors and preschoolers’ internalized conduct. The bootstrapping result suggested that the indirect effect is statistically significant.Conclusion: This study explored an area of morality that is less researched and incorporated the importance of executive function into it. Additionally, the results confirmed the mediating effect of preschoolers’ executive function on their conscience. The results obtained are expected to help organize activities for developing morality.

Parental Mentalization and Early Parent-Child Interaction in Mothers with Affective Disorders or Borderline Personality Disorder: A Systematic Review

The ability to mentalize is central in the context of the parent-child relationship.The parental competence to see the child'smental state as an independent individual is an essential prerequisite for perceiving and interpreting child signals appropriately.These abilities are crucial but not always available under elevated stress levels when confronted with a child's affects and parenting challenges. Despite the clinical and conceptual relevance of mentalization with borderline personality disorder (BPD) and affective disorders, the subject has rarely been systematically addressed in parents.This review provides a systematic overview of parental mentalization in mothers with affective disorders or BPD and its impact on the quality of maternal interactive behaviour. The findings generally revealed a negative association between mothers' parental mentalization and depression or BPD, which varied greatly depending on the mentalization constructs. Both psychiatric diagnosis and current severity of symptoms were found to be relevant. However, some positive aspects of mentalization were not markedly impaired. Further, a lowermentalizing abilitywas associatedwith reduced sensitive behaviour in depressedmothers. The results contribute to a better understanding of the association between mentalization and maternal psychopathology and help refine early interventions in parent-child settings.

Computer-based mother–infant interaction analysis and mental functioning in postpartum depression

BackgroundAmong mothers suffering from postpartum depression (PD), 10–13% additionally experience a mother–infant interaction disturbance that causes a severe mental health risk for the infant. Besides depressive symptomology, the underlying factors promoting dysfunctional maternal interaction behavior have not yet been sufficiently investigated. Therefore, we examined potential relationships between computer-based mother–infant interaction among postpartum depressed dyads and maternal mental functioning. MethodsMother–infant interaction was video-recorded and evaluated via a computer-based micro-interaction analysis program (INTERACT). We included only 25 hospitalized mother–infant dyads that fulfilled the diagnostic criteria of PD and tested mothers on their mental functioning (empathy, theory of mind, meta-cognition and alexithymia). ResultsBehavioral interaction analyses indicated that mothers with PD were prone to inactive maternal behavior, less positive maternal behavior along with more rejective behavior and also disengaged affect towards the infant. Distortions in mothers’ mental functioning may have had an influence on the dysfunctional patterns of mother–infant dyads. ConclusionsCognitive and social functioning could be an influencing factor on dysfunctional maternal interaction behavior. Early detection of distortions of mental processing in expectant mothers might help to inhibit the clinical manifestation of dysfunctional mother-infant bonding and negative child outcome in PD.

Families With Violence Exposure and the Intergenerational Transmission of Somatization.

Introduction:Adults who have histories of childhood trauma have been noted to display greater somatization, dissociative symptoms and affect dysregulation. What happens in the parent-child relationship when those traumatized children become parents? A potential link to somatization in the child has been suggested by several prior studies. Children who have early attachment disturbances had more physical complaints if their mothers displayed less maternal sensitivity during observed parent-child interactions. Yet, the intergenerational link between maternal and child somatization has not been sufficiently explored in a longitudinal study in order to understand the potential impact of maternal trauma history and related psychopathology on subsequent child somatization and psychopathology.MethodsThis paper examined prospective, longitudinal data of 64 mother-toddler dyads (mean age = 2.4 years, SD = 0.7) who were later studied when children had a mean age of 7 years. Mothers with and without histories of interpersonal violence (IPV; physical/sexual abuse and/or family violence exposure) were included. Mothers with IPV histories were oversampled. Linear and Poisson regression models were used to test the associations between maternal IPV-related post-traumatic stress disorder (PTSD) with maternal somatization severity when children were toddlers, and between maternal somatization and maternal interactive behaviors with child somatization by maternal report and clinician-rated assessment at school-age.ResultsMaternal PTSD severity was significantly associated with increased maternal somatization severity (p = 0.031). Maternal somatization severity during the child's early childhood predicted both maternal report of child somatization (p = 0.011) as well as child thought problems (p = 0.007) when children were school-aged. No association was found between maternal somatization and child-reported psychopathology. The study did not find that maternal alexithymia, caregiving behaviors or child exposure to violence contributed significantly to the model examining the association between maternal and child somatization.ConclusionThe results are in line with the hypothesis of intergenerational transmission of somatization in the context of IPV and related maternal PTSD during formative early development. We interpret this as an expression of psychological distress from mother to child, as maternal trauma and pathology affect the caregiving environment and, thus, the parent–child relationship. The authors conclude with a discussion of implications for parent–infant and early childhood intervention.

Patterns of maternal interactive behaviors and dual vocabulary development in Mexican American children.

Children learn the words of their native language(s) from interactions with their caregivers. Although previous research has found that the language children hear during those interactions predicts vocabulary outcomes, few studies have investigated how qualitative features of social interactions work together to affect children's vocabulary development, particularly for underresourced, language minoritized children. This study examined patterns of maternal interactive behaviors during toddlerhood in relation to children's later Spanish and English vocabulary development among 318 low-income, Mexican American families. Five maternal behaviors (acknowledging, elaborating, gaze, vocal appropriateness, and overriding) were coded from video recordings at age 24 months. At 36 and 54 months, child expressive vocabulary was assessed in both English and Spanish. Latent class analysis identified five distinct patterns of maternal interactive behaviors, which differentially supported or compromised child expressive language in English and Spanish. Implications of these findings for better understanding the role of caregiver interactions in dual language vocabulary development are discussed.

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 maternal care and amygdala habituation to emotional stimuli in adulthood.

Evidence suggests that maternal care constitutes a protective factor for psychopathology which may be conditional on the level of family adversity. Given that psychopathology is frequently linked with social deficits and the amygdala with social functioning, we investigated the impact of early maternal care on amygdala function under high vs low familial risk for psychopathology. Amygdala activity and habituation during an emotional face-matching paradigm was analyzed in participants of an epidemiological cohort study followed since birth (n = 172, 25 years). Early mother–infant interaction was assessed during a standardized nursing and play setting at the age of 3 months. Information on familial risk during the offspring’s childhood and on the participants’ lifetime psychopathology was obtained with diagnostic interviews. An interaction between maternal stimulation and familial risk was found on amygdala habituation but not on activation, with higher maternal stimulation predicting stronger amygdala habituation in the familial risk group only. Furthermore, amygdala habituation correlated inversely with Attention Deficit Hyperactivity Disorder (ADHD) diagnoses. The findings underline the long-term importance of early maternal care on the offspring’s socioemotional neurodevelopment and of interventions targeting maternal sensitivity early in life, particularly by increasing maternal interactive behavior in those with familial risk.

Transição para educação infantil: estudo comparativo do processo de vinculação primária e secundária

O presente artigo buscou: 1) descrever e comparar: a) a qualidade do vínculo entre o bebê-mãe e bebê-educadora, aos nove e doze meses de vida; b) a percepção do temperamento do bebê pelas mães e educadoras e, 2) correlacionar os indicadores de vinculação com os escores obtidos nas escalas de temperamento. Participaram nove bebês e suas respectivas mães e duas educadoras que responderam a escala de temperamento e foram filmadas individualmente com os respectivos bebês, aos nove e doze meses. Os resultados indicaram a presença de vinculação primária com a mãe e secundária com a educadora, ambas satisfatórias. Não houve correlações entre temperamento e comportamentos interativos na interação mãe-bebê, mas foram observadas entre educadora-bebê. Embora o vínculo mãe-bebê seja mais forte, a qualidade estabelecida com as educadoras sugere que a transição para a educação infantil pode ser positiva.

An Observational Study on Early Dyadic Interactive Behaviors of Mothers With Early-Preterm, Late-Preterm, and Full-Term Infants in Malawi.

Mother-infant interactions are necessary for infant growth and development. However, preterm birth is associated with less positive mother-infant interactions than full-term birth. Malawi has the highest preterm birth rate in the world, but studies of the mother-infant relationship in Malawi are limited and studies that observed mother-infant interactions could not be located. This study explored mother-infant interactions among Malawian mothers of early-preterm, late-preterm, and full-term infants. This observational study explored maternal and infant interactive behaviors. We recruited 83 mother-infant dyads (27 early-preterm, 29 late-preterm, and 27 full-term dyads). Mothers of early-preterm infants looked at and rocked their infants less, and their infants looked at their mothers less, than mothers of either late-preterm infants or full-term infants. The infants in all groups were asleep most of the time, which contributed to low levels of interactive behaviors. Factors that were related to infant behaviors included marital status, maternal occupation, maternal education, infant medical complications, infant gender, history of neonatal deaths, and multiple births. Our findings provide evidence about the need to encourage mothers to engage interactive behaviors with their infants. Future studies of factors that contribute to positive interactions in Malawi are needed.

Examining the role of mother-child interactions and DNA methylation of the oxytocin receptor gene in understanding child controlling attachment behaviors

ABSTRACT This study examined mother-child interactions and DNA methylation of the oxytocin receptor (OXTR) gene in the child, in relation with controlling-attachment behaviors at early preschool age. Maternal interactive behaviors were coded using the Emotional Availability Scales, and child attachment behaviors were assessed with the Separation-Reunion procedure and coded with the Preschool Attachment Rating Scales. DNA methylation data were captured from exon 3 of the OXTR. Results indicated that lower maternal sensitivity was associated with more controlling-caregiving behaviors, and that less maternal structuring was associated with more controlling-punitive behaviors. Hypomethylation of the OXTR gene was associated with greater maternal structuring behaviors, and with more child controlling-caregiving behaviors. The moderating role of the OXTR gene was examined in the association between interactive behaviors and child controlling behaviors, but no interaction effect was found. These results suggest that maternal interactive behaviors and OXTR methylation are independently associated with child controlling attachment.

A Randomized Trial of Continuous Versus Intermittent Skin-to-Skin Contact After Premature Birth and the Effects on Mother-Infant Interaction.

Premature birth affects opportunities for interaction between infants and mothers. Skin-to-skin contact (SSC) is standard care in neonatal care but has not been sufficiently studied regarding the effects on interaction between preterm infant and mothers. The purpose of this study was to compare interaction between preterm infants and their mothers after continuous versus intermittent SSC from birth to discharge. A secondary aim was to study a potential dose-response effect between time in SSC and quality of interaction. Families were randomly assigned to either continuous (n = 17) or intermittent (n = 14) SSC before delivery. Interaction was measured from videotapes of a Still-Face Paradigm collected at 4 months' corrected age. Face-to-face interaction was coded according to Ainsworth's Maternal Sensitivity Scales and the Maternal Sensitivity and Responsivity Scales-R. Dose-response correlations were calculated between mean time spent in SSC and each of the interaction scales. There were no statistically significant differences between groups in maternal interactive behavior toward their infants regarding sensitivity, interference, availability, acceptance, withdrawal, or intrusivity. There was no correlation between mean time in SSC and quality of interaction. Continuous SSC from birth to discharge was not superior to intermittent SSC concerning mother-infant interaction between preterm infants and their mothers at 4 months' corrected age. However, compared with other studies, mean time in SSC was also high in the intermittent group. Further studies are needed to find out how interaction between parents and preterm infants can be improved, supported, and facilitated in the neonatal intensive care unit (NICU) and whether there is an optimal dose for SSC.

Interação mãe bebê com deficiência: um estudo de revisão

Ao nascer, o bebê e a mãe passam por um processo de adaptação, que requer adequações na rotina. A interação mãe-bebê é importante para a qualidade do desenvolvimento infantil. Entretanto, ela pode ser prejudicada quando a mãe não consegue se adaptar às exigências da nova condição que, em geral, exige outras organizações e rotinas mais elaboradas. O objetivo do presente estudo foi analisar artigos que abordam a interação mãe-bebê com deficiência. A busca de artigos foi realizada nas bases de dados online Pubmed, Scielo, Capes, Google Acadêmico, BVS e Parthernon. Foram selecionados 28 artigos, dos quais 71,44% eram internacionais, prevalecendo a publicação em revistas de Fonoaudiologia. Como objetivo os artigos: compararam a interação mãe bebê com e sem deficiência auditiva; analisaram o comportamento interativo materno; identificaram os fatores de risco para a interação; relacionaram a interação mãe-bebê com o desenvolvimento infantil e testaram a confiabilidade de protocolos que codificam a interação. Dos artigos, 35,71% avaliaram uma a 15 díades, 53,57% eram com crianças de 0 a 2 anos e, em 85,71% as mães eram as participantes. Quanto ao delineamento, prevaleceram estudos comparativos (46,38%), o procedimento mais utilizado foi a filmagem (85,71%), com duração de 16 a 30 minutos (60%), realizando de dois a cinco episódios (40%) e as atividades mais frequentes foram alimentação, higiene, leitura de livros e jogos. Sugere-se que novos estudos abordem a presente temática, a fim de auxiliarem no desenvolvimento de intervenções na interação mãe-bebê com deficiência.
