Preterm infant development, maternal distress and sensitivity: The influence of severity of birth weight

Improving Maternal Depression Screening in the Neonatal Intensive Care Unit

PURPOSE

To examine whether self-perceived benefits of mental health treatment differed between mothers of babies in the neonatal intensive care unit with and without a positive screen for depression based on their Edinburgh Postnatal Depression score.

STUDY DESIGN AND METHODS

Mothers were recruited in person pre-COVID-19 pandemic, and via phone call and online advertisement during the pandemic. Mothers completed a 10-item depression scale and whether they believed they would benefit from mental health treatment. A chi-square test determined the difference in perceived benefit between mothers who screened positively for depression and those who did not.

RESULTS

This secondary analysis included 205 mothers, with an average age of 29. Of the 68 mothers who screened positively for depression, 12 believed that would not benefit from mental health intervention. Of the 137 who screened negatively for depression, 18 believed they would benefit from mental health intervention. Mothers who screened negatively for depression were significantly less likely to believe they would benefit from mental health intervention.

CLINICAL IMPLICATIONS

Depression screening scales offer guidance on which mothers to flag for follow-up, but neither on how a mother will respond nor how to effectively approach a mother about her mental health. Nurses can improve identification and follow-up of depressed mothers in the neonatal intensive care unit by asking mothers about their perceived need for mental health treatment.

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.

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.

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.

Living with a birthmark: Phenomenology of prematurity for mothers in Turkey

BACKGROUND

Mothers of premature infants are in the risk group for having psychological symptoms and attachment-interaction difficulties. Preventing these maternal risks is essential for providing optimal care and health opportunities for infants, consequently improving developmental outcomes.

METHODS

In this study, we aimed to understand how mothers experienced prematurity within four processes retrospectively: (a) the mother's hospitalization after birth, (b) the infant's hospitalization in the Neonatal Intensive Care Unit (NICU), (c) after discharge, and (d) in early childhood. We adopted Max van Manen's phenomenology of practice and interviewed nine mothers whose children were born premature and reached early childhood.

FINDINGS

The themes were as follows: (a) incomplete mother; (b) facing prematurity, uncertainty, natural touch barrier, facing reductive social response, and NICU friendship; (c) being on the alert, a period of complete closure, and fighting with the reductive social response; (d) association to prematurity and (cannot) overcome the difficulties. We expressed the mothers' overall experiences through the metaphor "living with a birthmark." This metaphor represents the longitudinal effects of prematurity. As much as it is apparent and painful at first, it fades over time, and the pain lessens, but the effects of the birthmark remain in early childhood. The birthmark becomes a part of the mother-baby relationship.

CONCLUSIONS AND PRACTICE IMPLICATIONS

Our study contributes to premature infant care and health literature by highlighting the longitudinal experiences of mothers on prematurity.

Depressive Symptoms in Fathers during the First Postpartum Year: The Influence of Severity of Preterm Birth, Parenting Stress and Partners’ Depression

Although preterm birth constitutes a risk factor for postpartum depressive symptomatology, perinatal depression (PND) has not been investigated extensively in fathers of very low (VLBW) and extremely low birth weight (ELBW) infants. This study explored paternal depression levels at 3, 9, and 12 months of infant corrected age, investigating also the predictive role played by the severity of prematurity, maternal and paternal PND levels, and parenting stress. We recruited 153 fathers of 33 ELBW, 42 VLBW, and 78 full-term (FT) infants, respectively. Depression was investigated by the Edinburgh Postnatal Depression Scale (EPDS) and distress by the Parenting Stress Index-Short Form-PSI-SF (Total and subscales: Parental Distress, Parent–Child Dysfunctional Interaction, and Difficult Child). ELBW fathers showed a significant decrease (improvement) in EPDS, total PSI-SF, and Parental Distress mean scores after 3 months. Paternal EPDS scores at 12 months were significantly predicted by VLBW and FT infants’ birth weight categories, fathers’ EPDS scores at 3 and 9 months, Parent–Child Dysfunctional Interaction subscale at 3 months, and Difficult Child subscale at 9 months. This study strengthens the relevance of including early routine screening and parenting support for fathers in perinatal health services, with particular attention to fathers who might be more vulnerable to mental health difficulties due to severely preterm birth.

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.

Mother-Infant Dyadic Synchrony in the NICU Context

BACKGROUND

Dyadic synchrony is a co-constructed social process relating to the back and forth interactions between mothers and infants that are strongly associated with neurodevelopment, self-regulation, and attachment. In the neonatal intensive care unit (NICU), this process may become interrupted because of the physiological state of the infant, the emotional state of the mother, and the physical environment of the NICU.

PURPOSE

In applying Feldman's Biobehavioral Model of Synchrony, this empirical review deconstructs the process of dyadic synchrony in the NICU context and provides a conceptual approach to guide both research and clinical practice.

METHODS

First, we examine the theoretical and empirical literature to explicate the primary structural and biophysiological components of synchrony and relate these constructs to the extant research on premature infants. Next, we synthesize the maternal, infant, and contextual factors that facilitate or inhibit the ontogenesis of dyadic synchrony in the NICU. The final section highlights the state of the science in dyadic synchrony in the NICU including gaps and recommendations for future research.

FINDINGS

An empirical review synthesis presents a visual conceptual framework to illustrate multiple processes that depict maternal, infant, and contextual influences of mother-infant synchrony in the NICU.

IMPLICATIONS FOR PRACTICE/RESEARCH

Despite the challenges posed to mother-infant relationships in the NICU, high-quality mother-infant interactions are possible, dyadic synchrony can emerge, and premature infants can develop secure attachments. Clinicians and researchers can apply this conceptual framework of mother-infant dyadic synchrony in the NICU to promote evidence-based research and clinical practice.

Parenting Record Handbook: The Needs of Mothers Raising Low Birth Weight Infants

This study investigated the necessity for a parenting record handbook that is specifically tailored to the needs of low birth weight infants (LBWIs) and their families, especially mothers, who face parenting difficulties and challenges. The participants were 20 mothers, raising LBWIs, discharged from the neonatal intensive care unit. The mean age and weight of the children were 2.75 ± 0.35 years and 1417.50 ± 152.06 g, respectively; the mean duration of neonatal intensive care unit hospitalization was 78.75 ± 14.10 days. At the time of the study, 35% (7/20) were nursery children, 10% (2/20) were kindergarten children, 20% (4/20) were using rehabilitation centers, and 10% (2/20) were using the medical rehabilitation handbook. The needs of the mothers were investigated through focus group interviews or individual interviews, and content analyses were performed. The mothers required the promotion of peer support that assists the alleviation of mental burden and postpartum mental and physical care, as well as the publication of counseling service counters and reliable information sources for parenting difficulties in the parenting record handbook. The mothers required the publication and recording of the growth indicators of LBWIs, parenting records, information management of children since birth, and for the handbook to function as a multidisciplinary information sharing tool. In addition, the requirements for the parenting record handbook were the early provision of the parenting record handbook and measures to cope with poor maternal physical condition. The results of this study suggest that mothers with LBWIs require a parenting record handbook that can provide comprehensive maternal and child health assurance, starting from pregnancy, to resolve childcare difficulties for LBWIs, as well as mental support.

Spontaneous movements, motor milestones, and temperament of preterm-born infants: Associations with mother-infant attunement

Preterm-born infants and their mothers are at higher risk of showing less attuned interactions. We sought to identify characteristics of preterm-born infants associated with the attunement of mother-infant interactions at the corrected ages of 3-4 months, looking specifically at motor behaviors. We focused on infants' spontaneous movements, achievement of motor milestones, and temperament, which at this young age is often manifested via movement. Sixty preterm-born infants (Mdn_{gestation age in weeks}  = 33, 57.38% male, corrected age Mdn = 14 weeks, interquartile range = 13-16) and their mothers participated. Independent observers rated mother-infant attunement, infants' spontaneous movements, and infants' achievement of motor milestones. Mothers reported infant temperament. We found infants' smooth and fluent movement character and continual fidgety movements were associated with better attunement in terms of higher maternal sensitivity and non-intrusiveness and higher infant responsiveness and involvement. Unexpectedly, infants' achievement of motor milestones was not significantly associated with mother-infant attunement, and maternal reports of infants' higher soothability were associated with lower maternal sensitivity. The study illustrates the value of including the assessment of infants' spontaneous movements, designed for early detection of neurological deficiencies, in research and in clinical practice with parents and preterm-born infants.

Parental Book-Reading to Preterm Born Infants in NICU: The Effects on Language Development in the First Two Years

Background: After preterm birth, infants are at high risk for delays in language development. A promising intervention to reduce this risk is represented by the exposure to parental voices through book-reading in Neonatal Intensive Care Units (NICU). This study investigated the possible advantages of book-reading to preterm neonates during their NICU stay on their subsequent language development. Methods: 100 families of preterm infants were recruited. The parents of 55 preterm infants (Reading Group) received a colored picture-book on NICU admission and were supported to read to their neonate as often as possible and to continue after hospital discharge. Forty-five infants (Control Group) were recruited before the beginning of the intervention. Infant language development was assessed with the Hearing and Language quotients of the Griffith Mental Development Scale at the corrected ages of 3, 6, 9, 12, 18 and 24 months. Results: Regardless of group membership, Hearing and Language mean quotients decreased between 9 and 18 months; nevertheless, this decrease was considerably reduced in the Reading group, compared to the Control Group. Conclusions: Reading in NICUs represents a suitable intervention that could positively influence language development and parent-infant relationships in preterm children. The study findings support its implementation as a preventive measure.

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.

Comparison of the number of live births, maternal age at childbirth, and weight of live births between Korean women and immigrant women in 2018

Purpose

This study compared maternal age at childbirth, the number of live births, and the weight of live births between Korean women and immigrant women using statistical data from the Republic of Korea for the period of 2008-2018.

Methods

The analysis was conducted using data from the Microdata Integrated Service of Statistics Korea (https://mdis.kostat.go.kr/index.do).

Results

Korean women and immigrant women showed a higher age at childbirth in 2018 than in 2008. The percentage of newborns of Korean women with a birth weight of less than 2.5 kg increased slightly for 3 consecutive years from 2016 to 2018, whereas for immigrant women, this percentage increased in 2017 compared to 2016 and then decreased again in 2018. Very low birth weight (less than 1.5 kg) became more common among immigrant women from 2016 to 2018. Birth at a gestational age of fewer than 37 weeks increased both among Korean and immigrant women from 2016 to 2018. In both groups, the percentage of women who had their first child within their first 2 years of marriage decreased from 2008 to 2018.

Conclusion

Immigrant women had higher birth rates than Korean women, while both groups showed an increasing trend in preterm birth. Greater attention should be paid to the pregnancy and birth needs of immigrant women, and steps are needed to ensure health equity and access in order to prevent preterm births. It is also necessary to identify factors that affect preterm birth and birth of very low birth weight infants among immigrant women in the future.

Developmental outcome of extremely preterm infants is improved after less invasive surfactant application: Developmental outcome after LISA

AIM

The aim of this study was to evaluate neurocognitive outcome at 24 months of corrected age after less invasive surfactant application (LISA) in preterm infants born at 23-26 weeks of gestational age.

METHODS

Surviving participants of a LISA trial conducted in 13 German level III neonatal intensive care units were reviewed for assessment of developmental outcome, hearing and vision problems, growth and rehospitalisation days. Maternal depression, breastfeeding rates and socio-economic factors were evaluated as potentially confounding factors.

RESULTS

In total, 156/182 infants took part in the study, 78 had received surfactant via LISA and 78 via endotracheal intubation. 22% of LISA infants compared to 42% of intubated infants had a psychomotor development index (PDI) <70 (0.012). A significant difference in mental development index (MDI) was observed in the stratum of more mature infants (25 and 26 weeks of GA). For this group, MDI < 70 was observed in 4% of LISA infants vs 21% of intubated infants (P = 0.008).

CONCLUSION

At 24 months of age, the LISA-treated infants scored less often PDI < 70 and had similar results in MDI. Infants born at 25 and 26 weeks treated with LISA had lower rates of severe disability. LISA is safe and may be superior.

Cardiac sympathetic activation and parasympathetic withdrawal during psychosocial stress exposure in 6-month-old infants

Infant autonomic reactivity to stress is a potential predictor of later life health complications, but research has not sufficiently examined sympathetic activity, controlled for effects of physical activity and respiration, or studied associations among autonomic adjustments, cardiac activity, and affect in infants. We studied 278 infants during the repeated Still-Face Paradigm, a standardized stressor, while monitoring cardiac activity (ECG) and respiratory pattern (respiratory inductance plethysmography). Video ratings of physical activity and affect were also performed. Respiratory sinus arrhythmia (RSA) and T-wave amplitude (TWA) served as noninvasive indicators of cardiac parasympathetic and sympathetic activity, respectively. Responses were compared between infants who completed two still-face exposures and those who terminated after one exposure due to visible distress. Findings, controlled for physical activity, showed robust reductions in respiration-adjusted RSA and TWA, with more tonic attenuation of TWA. Infants completing only one still-face trial showed more pronounced autonomic changes and less recovery from stress. They also showed elevated minute ventilation, suggesting hyperventilation. Both reductions in adjusted RSA and TWA contributed equally to heart rate changes and were associated with higher negative and lower positive affect. These associations were more robust in the group of distressed infants unable to complete both still-face trials. Thus, cardiac sympathetic activation and parasympathetic withdrawal are part of the infant stress response, beyond associated physical activity and respiration changes. Their association with cardiac chronotropy and affect increases as infants' distress level increases. This excess reactivity to social stress should be examined as a predictor of future cardiovascular disease.

Characteristics of Early Mother-Infant and Father-Infant Interactions: A Comparison between Assisted Reproductive Technology and Spontaneous Conceiving Parents

This study aims to describe parents’ and infant’s interactive styles after assisted reproduction treatments (ART), to compare them with parent–infant interactions after spontaneous conception (SC), and to assess the effect of specific ART variables (cause of infertility, treatment type, and previous ART attempts) on interaction quality. The sample included 25 ART conceiving couples and 31 SC couples with their 3-months-old babies. Free parent–infant interactions (3–5 min) were coded using the CARE-Index, a video-based assessment scale that gives both dimensional (e.g., sensitivity, control, passivity) and categorical scores (sensitive, inept, at-risk) for parents and infants. Results showed a global similarity between groups in CARE-Index dimensions. Nevertheless, differences emerged in categorical scores, as the interactive patterns of ART parents were more frequently classified as “inept” and “at-risk” compared to SC parents. With regards to ART dyads only, infants conceived through intracytoplasmic sperm injection scored significantly lower to the dimension compulsivity and higher to passivity, compared to infants conceived through in vitro fertilization. Yet, infants conceived at the first ART cycle had significantly lower levels of difficulty than infants conceived after one ART attempt. These results speak about the existence of important parent–infant interactive differences related to conception modality and ART technique and suggest the need to implement support programs to promote more sensitive parenting styles.

Mind-Mindedness and Parenting Stress: A Cross-Sectional Study in a Cohort of Mothers of 3-Month-Old Full-Term and Preterm Infants

The preterm birth of a child is a sudden event that can disturb the overall family system and its functioning. Many studies have been conducted with the aim of exploring how and the degree to which this event affects the early mother–infant dyadic relationship and maternal well-being, with often mixed findings. The present study investigates the combined effect of preterm birth and parenting stress on mind-mindedness, a parenting dimension that captures how parents represent and treat their children as separate individuals with their own mental states and activities. A hundred and ten mothers and their three-month-old infants (preterm = 54; full-term = 56) participated in the study. Mind-mindedness was assessed by coding mothers’ comments about infant’s mental states during dyadic face-to-face interaction. Parenting stress was evaluated with the Parenting Stress Index Short Form questionnaire. Mothers of preterm infants reported similar levels of appropriate and non-attuned mind-related comments to mothers of full-term infants. The reported parenting stress levels were also comparable. Interestingly, only mothers of preterm infants who reported higher stress in parenting showed more non-attuned comments during the interaction. The results underline the need to address preterm birth as a complex event, going beyond group differences and considering its interplay with other risk or protective factors in shaping children’s and parents’ adjustments and well-being.

South Korean nurses' lived experiences supporting maternal postpartum bonding in the neonatal intensive care unit

Purpose: Preterm birth and admission to a neonatal intensive care unit (NICU) can disrupt the parent-infant bonding relationship. Although neonatal nurses are in the best position to support maternal postpartum bonding in the NICU, few qualitative studies have described their challenges, strategies, and lived experiences. Methods: This study aimed to explore and understand the experiences and perspectives of nurses supporting infants hospitalized in the NICU and their families in relation to the bonding process. We conducted a qualitative study using interpretive phenomenological analysis with 12 in-depth, semi-structured interviews recorded and transcribed verbatim between April and November 2018. We thematically analysed the data using NVivoTM software. Results: Two themes emerged: (1) Being a bridge between separated mothers and infants (five subthemes); (2) Challenges in providing supportive care for maternal postpartum bonding in the NICU (three subthemes). Conclusions: Nurses have a variety of experiences regarding maternal postpartum bonding; however, the clinical reality of NICUs limits support for bonding formation. Although nurses face challenges (e.g., institutional policies, insufficient resources, training) when supporting maternal postpartum bonding, they act as the bridge between mothers and infants, becoming advocates for NICU families and taking care of their growth and developmental needs as caregivers.

Comparative Evaluation of Parental Stress Experiences Up to 2 to 3 Years After Preterm and Term Birth

Parenting stress after preterm birth (PTB) has negative long-term effects on parenting. Research about parental experiences after PTB and on parenting stress in early childhood has focused on mothers.

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

BACKGROUND

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.

PURPOSE

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.

METHODS

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.

RESULTS

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.

IMPLICATIONS FOR PRACTICE

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.

IMPLICATIONS FOR RESEARCH

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.

Developmental Dimensions in Preterm Infants During the 1st Year of Life: The Influence of Severity of Prematurity and Maternal Generalized Anxiety

BACKGROUND

The literature has recognized premature birth as a risk factor for infant development and maternal anxiety. This study investigated the impact of the severity of birth weight, as well as of maternal anxiety at 3 months of infants' corrected age, on infants' outcomes during the 1st year postpartum. Moreover, it described the longitudinal trajectories of developmental outcomes, additionally exploring the impact of anxiety.

METHODS

The study compared 147 mothers and their 147 newborns, differentiated in 25 Extremely Low Birth Weight (ELBW), 41 Very Low Birth Weight (VLBW), and 81 Full-Term (FT) infants. At 3, 9, and 12 months (corrected age in the case of preterm infants) the level of infants' development was investigated according to the 5 quotients (Locomotor, Personal and Social, Hearing and Language, Eye-hand Co-ordination and Performance) of the Griffiths Mental Development Scales (GMDS-R). During the assessment of 3 months, mothers fulfilled Penn State Worry Questionnaire (PSWQ) to evaluate the presence of generalized anxiety.

RESULTS

Among the 5 GMDS-R quotients, significant effect of severity of birth weight emerged only for Performance quotient: preterm infants (ELBW at 3 months; VLBW at 12 months) showed lower scores than FT ones. Moreover, this quotient decreased from 3 to 9 and to 12 months for VLBW and FT infants, while it was stable for ELBW ones. A significant interaction between severity of birth weight and maternal anxiety emerged for Hearing and Language and Locomotor quotients. In the first case, scores for ELBW infants, independently from maternal anxiety, decreased from 9 to 12 months. The same results emerged for VLBW infants, in the case of non-anxious mothers. Regarding Locomotor quotient, mean scores decreased from 3 to 9 and to 12 months for all groups in the case of non-anxious mothers. Conversely, when mothers were anxious, this decrease emerged only for VLBW infants. Lastly, ELBW, VLBW and FT showed difference in the growth and slope of the trajectories of different quotients.

CONCLUSION

The severity of birth weight for preterm infants, also in interaction with maternal anxiety, had significant and specific impact on different dimensions of infants' development. Clinical implications of these results underline the need for individualized interventions.

Psychometric properties of the Persian version of postpartum distress measure scale

BACKGROUND

The purpose of the present study was to determine psychometric properties of the Persian version of Postpartum Distress Measure Scale (PDM Scale).

METHODS

In this psychometric explorative study, the data were collected using a questionnaire containing demographic information, PDM Scale, and Depression and Anxiety Stress Scale-21 (DASS-21). The content, face and construct validity of the questionnaire was examined with participation of ten experts, 10 and 150 women referring to health care centers, who were under common care during their postpartum period, respectively. The concurrent validity of the tool was evaluated using DASS-21. The reliability of the items was evaluated with the participation of 30 women, calculating Cronbach's alpha coefficient and intra-class correlation coefficient.

RESULTS

The Content Validity Index, Content Validity Ratio and Impact Score of the Persian version of the PDM were 0.94, 0.73, and 2.97, respectively. The ten items of the questionnaire were loaded in two factors (general distress and obsessive compulsive symptoms subscale). Those two factors explained 50.78% of the total variance of women's distress. Internal consistency of the items and stability of the results were confirmed by Cronbach's alpha of 0.72 and Intra-class correlation coefficient of 0.75.

CONCLUSION

According to the study results, the Persian version of PDM Scale has acceptable psychometric properties. Care providers and researchers can use it as a tool for screening anxiety, depression and obsessive-compulsive disorder in women.

Language nutrition for language health in children with disorders: a scoping review

The quantity and quality of child-directed speech-language nutrition-provided to typically-developing children is associated with language outcomes-language health. Limited information is available about child-directed speech to children at biological risk of language impairments. We conducted a scoping review on caregiver child-directed speech for children with three clinical conditions associated with language impairments-preterm birth, intellectual disability, and autism-addressing three questions: (1) How does child-directed speech to these children differ from speech to typically-developing children? (2) What are the associations between child-directed speech and child language outcomes? (3) How convincing are intervention studies that aim to improve child-directed speech and thereby facilitate children's language development? We identified 635 potential studies and reviewed 57 meeting study criteria. Child-directed speech to children with all conditions was comparable to speech to language-matched children; caregivers were more directive toward children with disorders. Most associations between child-directed speech and outcomes were positive. However, several interventions had minimal effects on child language. Trials with large samples, intensive interventions, and multiple data sources are needed to evaluate child-directed speech as a means to prevent language impairment. Clinicians should counsel caregivers to use high quality child-directed speech and responsive communication styles with children with these conditions.

Maternal Distress in the Neonatal Intensive Care Unit: A Concept Analysis

BACKGROUND

The neonatal intensive care unit (NICU) can cause significant psychological distress in a mother. There is no common definition of maternal distress in the NICU currently in use.

PURPOSE

To develop a clear conceptual understanding of maternal distress in the NICU using conceptual definitions and empirical findings.

METHODS/SEARCH STRATEGY

A literature search was conducted using EBSCOhost, MEDLINE, CINAHL, PsychINFO, and Google Scholar. The concept analysis was guided by Walker and Avant's (2011) guide.

FINDINGS/RESULTS

Maternal distress in the NICU consists of a combination of depressive, anxiety, trauma, and posttraumatic stress symptoms. The symptoms occur together on a spectrum and present differently in each mother. The antecedents to maternal distress are a NICU hospitalization and a perceived interruption to the transition to motherhood. Consequences of maternal distress in the NICU are issues with developing a healthy maternal-infant bond, adverse infant development, and decreased maternal quality of life.

IMPLICATIONS FOR PRACTICE

A complete understanding of maternal distress in the NICU will lead to increased awareness of adverse mental health states in this population.

IMPLICATIONS FOR RESEARCH

Identification of mothers at risk for maternal distress in the NICU, as well as the identification of antecedents and consequences related to the mother and the infant from maternal distress in the NICU. Using a single, clear definition of maternal distress in the NICU population will lead to a more cohesive body of literature.

Birth weight, verbal cognition in early adolescence, and lexical and reading skills in late adolescence: a formal mediation analysis using a potential outcomes approach

BACKGROUND

Oral and written language in late adolescence are influenced by many pre- and postnatal factors, including cognitive performance at earlier ages. We investigated whether the association between birth weight and lexical knowledge and reading comprehension in late adolescence (14-16 years) is mediated by verbal cognition during early adolescence (10-11 years).

METHODS

We conducted a mediation analysis via a potential outcomes approach to data from three United Kingdom (UK) prospective birth cohorts - The National Child Development Study (NCDS; year of birth (Y.B.) = 1,958; analytic sample size (A.N.) = 9,399; original sample size (O.N.) = 18,558), British Cohort Study (BCS70; Y.B. = 1,970; A.N. = 6,591; O.N. = 17,196), and Millennium Cohort Study (MCS; Y.B. = 2,000-2,001; A.N. = 3,950; O.N. = 18,552) - to evaluate the indirect effects of birth weight on lexical knowledge (BCS and MCS) and reading comprehension measures (NCDS) in adolescence.

RESULTS

We found an indirect effect but no statistically significant direct effects for the BCS and MCS cohorts. The proportion of the effect of birth weight on oral and written language in late adolescence mediated by early adolescence verbal cognition was 59.19% (BCS) and 8.41% (MCS) for lexical knowledge and 61.00% when the outcome was reading comprehension (NCDS). Sensitivity analyses, used to assess whether unmeasured variables could have affected our mediation estimates, showed that for reading comprehension, in NCDS, the indirect effect is robust; only unmeasured confounders highly correlated with the mediator and outcome (ρ = .68) would explain away the indirect effect. For lexical knowledge, smaller correlations with hypothetical confounders (ρ = .33 for BCS) would suffice to render the indirect effect non-significant; the indirect effect for MCS non statistical significant.

CONCLUSIONS

Birth weight affects oral and written language skills (lexical knowledge and reading comprehension) in late adolescence via verbal cognition in early adolescence in two cohorts born in 1958 and 1970, but not in a cohort born at the turn of the millennium. These indirect effects were stronger than the direct effects and are unlikely to be explained by unmeasured confounders when the outcome involves complex skills such as reading comprehension.

Experiences of Mothers of Extremely Preterm Infants after Hospital Discharge

PURPOSE

The purpose of this study was to describe and understand the experiences of mothers of extremely preterm infants during the first twelve months at home following discharge from a neonatal intensive care unit.

DESIGN AND METHODS

A qualitative, interpretative approach using Gadamer's philosophical hermeneutics was carried out. One focus group and fifteen in-depth, semi-structured interviews were conducted twelve months after hospital discharge. Responses were recorded, transcribed and analyzed using computer-assisted qualitative data analysis.

RESULTS

The study´s participants were twenty women. The following themes emerged from the data analysis: 1) 'The journey home: the discharge process', which included the sub-themes 'escaping the hospital environment: between desire and fear' and 'preparing parents for hospital discharge: practice and formal support'; and 2) 'The difficulty of living with an extremely preterm infant', including the sub-themes 'the challenge of an unexpected form of childcare', 'overprotection of and bond with a child with special needs' and 'disturbance in the social/familiar setting: when a mother becomes a nurse'.

CONCLUSIONS

The process of hospital discharge and the first months at home are difficult. The birth and care of an extremely preterm infant affect the mothers' quality of life as well as their family and social life. Practice and early discharge programmes can make the discharge process easier.

PRACTICE IMPLICATIONS

The knowledge and understanding of the experience of mothers of extremely preterm infants in the first months at home after hospital discharge could help healthcare professionals to develop educational strategies and counselling interventions in accordance with the mothers' needs.

Persistence of Effects of VLBW/PT Birth Status and Maternal Emotional Availability (EA) on Child EA Trajectories

Few studies have examined the longitudinal impact of birth status on the infant-mother relationship and on children's socio-emotional development. In the present study we investigated developmental patterns of such relationships [using the Emotional Availability (EA) Scales] in fullterm and VLBW/PT infants from infancy to emerging school age. Our objectives were to: (a) model the developmental trajectories of EA dimensions (maternal sensitivity, structuring, non-hostility; child responsiveness, involvement) in a VLBW/PT and fullterm sample, (b) identify potential effects of VLBW/PT status on these trajectories, and (c) determine whether the effects of VLBW/PT status on children's socio-emotional development (child EA) remained after accounting for the effect of maternal EA. Child-mother dyads (n = 109) were observed in home-based interactions (face-to-face and free play) when children were 6, 12, 18, and 57-months-old in fullterm (37-41 weeks, >2500 g; n = 48) and healthy VLBW/PT (26-32 weeks gestation, birth weight 800-1500 g, corrected for gestational age; n = 61) children. Developmental trajectories of maternal and child EA were assessed using multilevel growth modeling in Mplus. Results indicated that, even after controlling for maternal EA, there was a persistent negative effect of VLBW/PT birth status on child EA trajectories. Both initially and over time, VLBW/PT infants lagged behind their fullterm counterparts on levels of responsiveness and involvement with mothers. There was also a persistent positive effect of maternal EA (sensitivity and structuring) on child EA trajectories. Higher average levels of maternal sensitivity and structuring across time were also associated with higher and persistent levels of child responsiveness and involvement of their mothers. Importantly, results held after modeling both effects together, and after controlling for maternal education and child gender. Our results have implications for VLBW/PT children's development, the parent-child relationship, and integrating family level factors and relationship dimensions in early prevention and intervention programs.

Maternal sensitivity is associated with configural processing of infant's cues in preterm and full-term mothers

BACKGROUND

Prematurity may affect mother-infant bonding and alter maternal sensitivity to infant's cues. Efficient perception of infants' facial and bodily cues is a crucial aspect of maternal sensitivity and may be challenged by prematurity, as infants' signals may not be easily intelligible. However, it is still unexplored how premature birth impacts the maternal ability to perceive infants' signals.

AIMS

To investigate whether prematurity influences the perceptual sensitivity of mothers to infants' cues and, in particular, the configural processing of the faces and bodies of familiar and unfamiliar infants.

STUDY DESIGN

The inversion effect paradigm was used to evaluate the configural vs. detail-based processing of the face and body of own or others' infants. Preterm mothers were compared to full-term mothers with either low or high maternal sensitivity.

PARTICIPANTS

Forty-three healthy full-term and twenty-one preterm mothers of infants aged about six months.

OUTCOME MEASURES

Maternal sensitivity during dyadic interaction, gestational age, accuracy and reaction time in a delayed matching-to-sample task of upright vs. inverted body and face stimuli (i.e., inversion effect).

RESULTS

Preterm mothers were found to be less sensitive than the full-term ones. Higher maternal sensitivity during dyadic interaction was associated with lower inversion effect for unfamiliar as compared to own infants' bodies. However, preterm mothers and full-term mothers with low sensitivity showed comparable inversion effect in perceiving unfamiliar infants' faces or bodies.

CONCLUSIONS

Preterm birth per se does not directly affect body configural processing, but it may be associated to reduced maternal sensitivity, ultimately leading to a less refined perception of own infant's cues.

Strategies of Increased Protein Intake in ELBW Infants Fed by Human Milk Lead to Long Term Benefits

Objective: The aim of this observational study was to evaluate the effects of two different protein intake regimes on feeding tolerance, in-hospital growth, anthropometric data and psychomotor outcome up to 24 months corrected age (CA) in extremely low birth-weight (ELBW; birth weight <1000 g) infants. Methods: During the period 2008-2013, 52 ELBW infants admitted at birth to two Neonatal Intensive Care Units of Emilia Romagna (Italy) were fed according to different protocols of protein fortification of human milk: an estimated protein intakes at maximum fortification levels of 3.5 gr/kg/day in the Standard Nutrition Population-SNP group (n = 26) and 4.8 g/kg/day in the Aggressive Nutrition Population-ANP group (n = 26). During hospitalization, infants' growth, biochemical indices of nutritional status, enteral intake, feeding tolerance, clinical history and morbidity were evaluated. After discharge, anthropometric data and psychomotor outcome, evaluated by Revised Griffiths Mental Development Scales (GMDS-R) 0-2 years, were assessed up to 24 months CA. Results: During hospitalization, the ANP group showed significantly higher weight (18.87 vs. 15.20 g/kg/day) and head circumference (0.70 vs. 0.52 cm/week) growth rates compared to SNP, less days of parenteral nutrition (7.36 ± 2.7 vs. 37.75 ± 29.6) and of hospitalization (60.0 ± 13.3 vs. 78.08 ± 21.32). After discharge, ANP infants had a greater head circumference compared to SNP (45.64 ± 0.29; 46.80 ± 0.31). Furthermore, the General Quotient of GMDS-R mean scores in the SNP group significantly decreased from 12 to 24 months CA, while no difference was seen in the ANP group. Conclusions: Increased protein intake may provide short and long term benefits in terms of growth and neurodevelopment in human milk-fed ELBW infants.

Impact of Neonatal Intensive Care Unit oral feeding on neuropsychomotor outcomes at 9 months of corrected age in Chinese low-birthweight preterm infants: A retrospective study

AIMS AND OBJECTIVES

To examine the changes in neuropsychomotor development and investigate the effect of feeding progression in Neonatal Intensive Care Unit (NICU) on neuropsychomotor outcomes in low-birthweight preterm infants within 9 months of corrected age.

BACKGROUND

Low-birthweight (LBW) preterm infants (<37 weeks of gestation and birthweight <2,500 g) are at a high risk for neuropsychomotor development delay. Therefore, exploring NICU practices related to neuropsychomotor development is important.

DESIGN

This is a retrospective hospital-based cohort study.

METHODS

This study included 196 LBW preterm infants who were admitted to the NICU between January 2014-March 2016 and attended the follow-up growth evaluation in the clinic after discharge. The neuropsychomotor development of preterm infants was assessed every 3 months to a corrected age of 9 months using the paediatric neuropsychomotor diagnostic scale (PNDS). Generalised linear mixed models (GLMM) were performed.

RESULTS

The total PNDS scores had a downward trend, but the difference on pairwise comparison was not statistically significant. In total, 18.1%, 15.2% and 9.7% of preterm infants were examined for neuropsychomotor disorders at 3, 6 and 9 months of corrected age, respectively. The result of GLMM showed that the early initiation of oral feeding with breast milk was associated with optimal neuropsychomotor development. The first 3 months of corrected age is the critical period for neurodevelopmental disorders.

CONCLUSIONS

This study showed the importance of the early initiation of oral feeding with breast milk as early as possible within the NICU setting and highlighted the importance of close developmental follow-up.

RELEVANCE TO CLINICAL PRACTICE

The early initiation of oral feeding with breast milk may be recommended to promote neuropsychomotor development of LBW preterm infants within the NICU setting. Early identification of neuropsychomotor developmental delays within the first 3 months may guide early interventions.

Effect of maternal psychopathology on neurodevelopmental outcome and quality of the dyadic relationship in preterm infants: an explorative study

Background: The literature shows that parents of preterm infants are at risk of psychological distress and that this may impact on the quality of the parent-child relationship and on the child's development.Aim: This longitudinal study was conducted to examine in preterm infants relationships between maternal psychological variables, parental protective factors, perinatal infant variables, and neurodevelopmental outcome. Furthermore, we explored the impact of these variables on the quality of the mother-infant relationship (dyadic synchrony).Subjects and methods: A total of 29 preterm infants (GA < 34 weeks) and their mothers were evaluated twice: at t₀, during the infant's hospitalization in the neonatal intensive care unit (NICU), and at 12 months of infant corrected age (t2).Results: With the exception of decreases in anxiety and perceived social support and an increase in the rate of severe depression at follow-up, there were no significant changes between t₀ and t₁ assessments. The infant's perinatal risk status was the variable that impacted most on maternal psychopathology. Furthermore, our data revealed that baseline maternal stress related to the appearance of the child and to the mother's perception of her parenting role represent a risk factor in relation to developmental outcome at 12 months of corrected age. Finally, no correlations emerged between dyadic synchrony and infant perinatal data, maternal psychological variables (at t₀ and at t₁), or child developmental outcome at t₁.Conclusions: Our results underline the need to identify negative maternal affective states early in the mother-child relationship and to provide mothers with adequate support in the NICU, to enhance their parental role.

Comparing Main, Goldwyn, and Hesse (Berkeley) and Crittenden (DMM) coding systems for classifying Adult Attachment Interview transcripts: an empirical report

Few studies have compared different systems in classifying Adult Attachment Interview (AAI) transcripts. In this study, the AAI was administered to 90 Italian parents (45 couples), and the AAI transcripts were independently classified according to Main, Goldwyn, and Hesse's (Berkeley) and Crittenden's (Dynamic-Maturational Model [DMM]) criteria. The two classification systems were not significantly associated, with some limited convergent results only when the interviews resulted in organized (Berkeley) and normative (DMM) attachment classifications. Otherwise, the Berkeley system identified more secure individuals than the DMM system, and many texts judged secure on the Berkeley system were identified as insecure on the DMM system. Since the Berkeley and the DMM systems rest on remarkably different conceptualizations of the nature and functioning of the attachment behavioral system (e.g. fear is conceived as organizing in the DMM and as potentially disorganizing in the Berkeley), the attachment classifications resulting from their applications should not be considered measurements of the same phenomena.

Mother- and father-infant interactions at 3 months of corrected age: The effect of severity of preterm birth

Early interactions of 92 preterm infants with their mothers (n=54) and fathers (n=38) were explored at 3 months using CARE-Index. Results showed differences in interactions based on parent's gender, with higher control in mothers and unresponsiveness in fathers, while no effect of severity of birth weight emerged.
