Abstract
Previous literature shows that aspects of temperament, executive functioning, and EEG frontal asymmetry are related to externalizing behaviors in children. We examined whether frontal EEG asymmetry measured at age 6 would moderate the impact of negative affectivity, attentional control, and working memory at age 6 on conduct problems at age 9. Behavioral tasks were given to assess children's attentional control and working memory. Parents completed questionnaires about their children's negative affectivity and conduct problems. Results showed that greater negative affectivity reported at age 6 predicted for more conduct problems reported at age 9, regardless of EEG frontal asymmetry. Lower levels of attentional control and working memory at age 6 predicted for more conduct problems reported at age 9 when children also exhibited greater left EEG frontal asymmetry, which has been linked to approach motivation. These findings illustrate the importance of assessing multiple intrinsic factors, both independent and interactive, that contribute to children's conduct problems.

J Pediatr Nurs 2023:S0882-5963(23)00106-9. [PMID: 37142495 DOI: 10.1016/j.pedn.2023.04.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 04/25/2023] [Accepted: 04/25/2023] [Indexed: 05/06/2023]
Abstract
PURPOSE To examine the relationship between NICU stress exposure and the neurodevelopmental outcomes of preterm infants. DESIGN AND METHODS A multicenter, prospective cohort study was conducted between May 2021 and June 2022. Preterm infant participants (28-34 weeks gestational age) were recruited at birth from three NICUs of three tertiary hospitals by convenience sampling. The NICU stress includes acute NICU stress and chronic NICU stress which were measured over the total NICU hospitalization for each infant using the Neonatal Infant Stressor Scale (NISS). Neurodevelopmental outcomes of preterm infants were assessed at 3 months corrected age (CA) using the Ages and Stages Questionnaire, Third Edition (ASQ-3). RESULTS Of one hundred and thirty preterm infant participants, 108 preterm infants were included into analysis. Results showed that acute NICU stress exposure significantly predicted the neurodevelopmental abnormalities in communication function (RR: 1.001, 95%CI: 1.000-1.001, p = .011), while chronic NICU stress exposure was significantly associated with the problem-solving function (RR: 1.003, 95%CI: 1.001-1.005, p = .002) at 3 months CA. No significant associations were found between NICU stress exposure and other dimensions of neurodevelopmental outcomes, including gross motor, fine motor, and personal-social functions. CONCLUSION NICU stress exposure demonstrated a significant predicting relationship with abnormalities in communication and problem-solving functions of preterm infants at 3 months CA. PRACTICE IMPLICATIONS During the NICU hospitalization, neonatal health caregivers should systematically monitor the NICU stress exposure to prevent neurodevelopmental problems in preterm infants.

Abstract
The aim of the present longitudinal study was to examine the effect of preterm childbirth, acute neonatal stress, and child behavior at 18-36 months of age on later behavior outcomes in 4-5-year-old children. The sample comprised of 70 children who were born preterm. The neonatal characteristics of children were assessed during hospitalization by reviewing their medical records and utilizing the Neonatal Infant Stressor Scale. Behavior problems were evaluated by the maternal-report in the Child Behavior Checklist 1½-5 years. A multiple linear regression analysis was conducted. Also, the repeated measures analysis of variance and the McNemar test for paired samples were performed. Daily exposure of the infants to high neonatal acute stress during NICU hospitalization and more behavior problems at 18-36 months of age was associated with more total and externalizing behavior problems at 4-5 years of age. Lower gestational age at childbirth and more internalizing behavior problems at 18-36 months was associated with more internalizing problems at 4-5 years old. The present study showed the combination of predictors of neonatal conditions and behavioral problems at childhood, highlighting the relevance of the implementation of developmental care in the NICU and follow-up the preterm infants after discharge programs.

Abstract
Our previous cross-sectional investigation (Chetcuti et al., 2020) showed that infants with autism traits could be divided into distinct subgroups based on temperament. This longitudinal study builds on this existing work by exploring the continuity of temperament subgroup classifications and their associations with behavioral/clinical phenotypic features from infancy to toddlerhood. 103 infants (68% male) showing early signs of autism were referred to the study by community healthcare professionals and seen for assessments when aged around 12-months (Time 1), 18-months (Time 2), and 24-months (Time 3). Latent profile analysis revealed inhibited/low positive, active/negative reactive, and sociable/well-regulated subgroups at each timepoint, and a unique reactive/regulated subgroup at Time 3. Cross-tabulations indicated a significant likelihood of children having a recurrent subgroup classification from one timepoint to the next, and no apparent patterns to the movement of children who did change from one subgroup to another over time. Temperament subgroups were associated with concurrent child social-emotional functioning and autism traits, but unrelated to child age, sex, or developmental level. These findings suggest that temperament subgroup classifications might represent a reliable and very early indicator of autism characteristics and social-emotional functioning among infants/toddlers with autism traits.

Abstract
Premature infants and infants later diagnosed with autism spectrum disorder (ASD) share many commonalities in clinical presentations. However, prematurity and ASD also have differences in clinical presentation. These overlapping phenotypes can lead to misdiagnoses of ASD or missing a diagnosis of ASD in preterm infants. We document these commonalities and differences in various developmental domains with the hope of aiding in the accurate early detection of ASD and timely intervention implementation in children born premature. Given the degree of similarities in presentation, evidence-based interventions designed specifically for preterm toddlers or toddlers with ASD may ultimately aid both populations.

Abstract
IMPORTANCE Internalizing (anxiety and/or depressive) behaviors are prevalent in children born very preterm (24-32 weeks' gestation). Procedural pain-related stress in the neonatal intensive care unit (NICU) is associated with long-term internalizing problems in this population; however, whether positive parenting during toddlerhood attenuates development of internalizing behaviors across childhood is unknown. OBJECTIVE To investigate whether neonatal pain-related stress is associated with trajectories of internalizing behaviors across 1.5, 3.0, 4.5, and 8.0 years, and whether supportive parenting behaviors and lower parenting stress at 1.5 and 3.0 years attenuate this association. DESIGN, SETTING, AND PARTICIPANTS In this prospective longitudinal cohort study, preterm neonates (born at 24-32 weeks' gestation) were recruited from August 16, 2006, to September 9, 2013, with follow-up visits at ages 1.5, 3.0, 4.5, and 8.0 years. The study was conducted at BC Women's Hospital, Vancouver, Canada, with recruitment from a level III neonatal intensive care unit and sequential developmental assessments performed in a Neonatal Follow-up Program. Data analysis was performed from August to December 2021. MAIN OUTCOMES AND MEASURES Parental report of child internalizing behaviors on the Child Behavior Checklist at 1.5, 3.0, 4.5, and 8.0 years. RESULTS A total of 234 neonates were recruited, and 186 children (101 boys [54%]) were included in the current study across ages 1.5 (159 children), 3.0 (169 children), 4.5 (162 children), and 8.0 (153 children) years. After accounting for clinical factors associated with prematurity, greater neonatal pain-related stress was associated with more internalizing behaviors across ages (B = 4.95; 95% CI, 0.76 to 9.14). Higher parenting stress at age 1.5 years (B = 0.17; 95% CI, 0.11 to 0.23) and a less supportive parent environment (less sensitivity, structure, nonintrusiveness, nonhostility, and higher parenting stress; B = -5.47; 95% CI, -9.44 to -1.51) at 3.0 years were associated with greater internalizing problems across development to age 8.0 years. CONCLUSIONS AND RELEVANCE In this cohort study of children born very preterm, exposure to repetitive neonatal pain-related stress was associated with persistent internalizing behavior problems across toddlerhood to age 8.0 years. Supportive parenting behaviors during early childhood were associated with better long-term behavioral outcomes, whereas elevated parenting stress was associated with more child anxiety and/or depressive behaviors in this population. These findings reinforce the need to prevent pain in preterm neonates and inform future development of targeted parent-led behavioral interventions.

Abstract
Childhood temperament is an early characteristic shaping later life adjustment. However, little is currently known about the stability of early temperament and its susceptibility to the environment in children born very preterm (VPT; <33 weeks’ gestation). Here, we investigated infant-to-childhood temperamental trajectories, and their interaction with parental practices, in VPT children. Maternal reports of infant temperament were collected in 190 infants (mean age: 11.27 months; range 9−18 months) enrolled in the longitudinal Evaluation of Preterm Imaging (ePrime; Eudra: CT 2009-011602-42) study, using the ePrime questionnaire on infant temperament. At 4−7 years of age, further assessments of child temperament (Children’s Behavior Questionnaire—Very Short Form) and parenting style (Arnold’s Parenting Scale) were conducted. Results showed that more difficult temperament in infancy was associated with increased Negative Affectivity in childhood, regardless of parenting practices. This lends support to the stability of early temperamental traits reflecting negative emotionality. In contrast, a lax parenting style moderated the relationship between easy infant temperament and Negative Affectivity at 4−7 years, such that an easier infant temperament was increasingly associated with higher childhood Negative Affectivity scores as parental laxness increased. These results highlight a potential vulnerability of VPT infants considered by their mothers to be easy to handle, as they may be more susceptible to the effects of suboptimal parenting in childhood.

Abstract
Postpartum depression is more prevalent in mothers and fathers of preterm infants compared to parents of full-term infants and may have long-term detrimental consequences for parental mental health and child development. The temperamental profile of an infant has been postulated as one of the important factors associated with parental depressiveness in the first months postpartum. This study aimed to examine the longitudinal relationship between depressive symptoms and perceived infant temperament at 3 months corrected age, and depressive symptoms at 6 months corrected age among mothers and fathers of infants born preterm. We assessed 59 families with infants born before the 34th gestational week using the Edinburgh Postnatal Depression Scale (EDPS) and the Infant Behavior Questionnaire-Revised. We found that mothers’ scores on EPDS and infants’ Orienting/regulation at 3 months corrected age predicted mothers’ EPDS scores at 6 months corrected age. In particular, higher depressive scores were related to higher depressive symptoms at 6 months corrected age, whereas higher infant Orienting/regulation was related to lower depressive symptoms at 6 months corrected age. Due to the low internal consistency of EPDS at 6 months for fathers, we were unable to conduct similar analyses for fathers. Our results point to the importance of considering both early indices of maternal mood as well as mother-reported measures of preterm infant temperament in the attempts to predict levels of maternal depressiveness in later months of an infant’s life. Further studies are urgently needed in order to better understand the associations between depressiveness and infant temperament in fathers, and with more consideration for the severity of the effects of infant prematurity.

Abstract
The central nervous system (CNS) of preterm infants might have some peculiarities which distinguish it from that of full term infants. The difficulties associated with prematurity are the main cause of deaths all over the world during the new-born period after community-acquired pneumonia, and the second cause of deaths worldwide in children under five years old. Early recognition of signs indicating fragile postural control in premature infants can support understanding and help prevent and early intervention on possible future neuromotor dysfunctions in these subjects. The purpose of this paper is to determine if there is a qualitatively different development of postural control in premature infants without neurological involvement and infants born at term. We conducted a systematic review of longitudinal and cross-sectional case-control studies published between 2010 and March 2020 on this topic. The evaluation of parameters related to postural control was also included. The methodological quality of the selected works was evaluated using the CASPe critical reading programme for cases and controls. PRISMA guidelines for systematic reviews were followed for prematurity and postural control. 16 articles were included. The total sample amounted to 3,460 participants, of which 1,860 in the preterm group, and 1,600 in the control group. All the studies found show a poorer postural control by the group of children born preterm compared to the group of children born at term and one study indicating more limited postural control with higher prematurity. Regarding the methodological quality according to CASPe, those studies exceeding half of the total score were considered of adequate quality.

Martins CBS, Cassiano RGM, Linhares MBM. Negative affectivity moderated by preterm birth predicted toddlers' behavior problems. Infant Behav Dev 2021; 63:101544. [PMID: 33618212 DOI: 10.1016/j.infbeh.2021.101544] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Revised: 02/13/2021] [Accepted: 02/13/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE The present study aimed to examine the predictive effect of temperament moderated by preterm childbirth on behavioral problems in toddlerhood. METHOD The sample comprised 100 toddlers of 18-36 months of chronological age and their mothers. They were divided into two groups: 50 toddlers born preterm and admitted to the Neonatal Intensive Care Unit (PT group), and 50 toddlers born full-term (FT group) and recruited from day-care centers. Mothers completed questionnaires about toddlers' temperament and behavior. The Early Childhood Behavior Questionnaire was used to assess temperament, and the Child Behavior Checklist (CBCL 1¹/²-5) to evaluate the total, internalizing, and externalizing behavior problems. Multiple regression analysis was performed to examine the moderation effects of preterm childbirth and temperament factors after controlling for toddlers' age and socioeconomic level. RESULTS There was a moderation effect between preterm childbirth and temperament. Temperament with more Negative Affectivity, moderated by preterm birth, and less Effortful Control explained the total, internalizing, and externalizing behavior problems. CONCLUSION The findings contribute to a better understanding of the impact of preterm childbirth and the dispositional traits of temperament on behavioral problems of toddlers born preterm.

Abstract
Preterm infants have a higher risk of showing visuospatial memory impairment, the function that allows to encode and remember visual and spatial information. It has been studied in late childhood in preterm children. Studies on visuospatial memory throughout the first 2 years of life are still scarce. Behavior, temperament, and overall cognition could be altered in preterm children affecting memory performance. Therefore, the main aim of this study was to evaluate short-term and visuospatial working memory performance in a preterm sample followed longitudinally at 12, 15, 18, and 22 months (N = 15), and compare their performance with that of full-term children (N = 65). The secondary aim was to analyze the course of mnesic development in preterm infants and relate their memory performance to other cognitive abilities and behavioral tendencies. Assessment included previously published tasks and an experimental paradigm. Results showed that preterm children scored lower than full-term children on visuospatial short-term and working memory at 12 and 22 months of age, although these results varied depending on the memory test used. Preterm children's memory results showed that these skills improve in this population between the first and second year of life. Finally, memory performance was directly associated with the level of cognitive development and the presence of proactive behaviors, while being inversely correlated with the presence of disruptive behaviors and a difficult temperamental style. These preliminary findings suggest that it is possible to detect visuospatial memory difficulties in the preterm population before the age of two.

Abstract
A randomized controlled trial study recruited 146 preterm born children, either to participate in a modified version of the Mother–Infant Transaction Program (MITP-m) or to receive the usual follow-up services, before and after discharge from a neonatal intensive care unit. This follow-up study investigates whether MITP participation is associated with parental perceptions of child temperament from two to seven years. Children’s temperament was reported by mothers and fathers separately at children’s ages of 2, 3, 5, and 7 years. Parents in the MITP-m group reported lower levels of negative emotionality in their children compared to the control group. In maternal reports, a group effect (F(1, 121) = 9.7, p = 0.002) revealed a stable difference in children’s negative emotionality from two to seven years, while a group-by-time interaction related to an increasing difference was detected in reports from fathers (F(1, 94) = 4.8, p = 0.03). Another group difference appeared in fathers’ reports of children’s soothability (F(1, 100) = 14.2, p < 0.0005). MITP-m fathers seemed to perceive their children as easier to soothe at all ages as no interaction with time appeared. Parental reports on children’s sociality, shyness, and activity did not differ between the groups.

Abstract
Objective To examine the effects of individual characteristics of neonates and neonatal pain-related stress on attention problems and externalizing behavior problems of toddlers born preterm, analyzing the moderating effects of the dispositional traits of temperament. Methods The sample included 62 toddlers aged 18-36 months and their mothers. The mothers were interviewed using the Child Behavior Checklist 1.5-5 for toddlers' attention and externalizing behavior problems assessment, the Early Childhood Behavior Questionnaire for toddlers' temperament assessment, and the Adult Temperament Questionnaire for their temperament assessment. The Neonatal Infant Stressor Scale analyzed the number of pain-related stress events during neonatal intensive care unit (NICU) hospitalization recorded in the medical charts. Statistical descriptive, correlation, and multiple linear regression analyses were performed. Results High neonatal pain-related stress total index, associated with toddler's temperament with less Effortful Control, and mother's temperament with high Surgency explained 23% variability of the attention problems. Otherwise, the externalizing behavior problems were explained by temperament, but not by neonatal pain-related stress. Conclusions The findings support the impact of neonatal pain experiences, and current toddlers' and mothers' temperament characterized by poorer self-regulation on attention problems in toddlers born preterm. Developmental care in the NICU and follow-up programs after discharge are recommended to promote regulated temperament of the mother-child dyads, aiming to prevent attentional problems in toddlers born preterm.

Abstract
OBJECTIVE The present study aimed to examine the predictor effects of neonatal, sociodemographic characteristics, and temperament assessed at 18-36 months of age on behavioral problems in 4- to 5-year-old children born preterm. METHODS The sample comprised 70 children born preterm. The amount and the intensity of stress procedures during a stay in the neonatal intensive care unit were evaluated using the Neonatal Infant Stressor Scale. Temperament was assessed using the Early Childhood Behavior Questionnaire, and behavioral problems were assessed using the Child Behavior Checklist 11/2-5. Multiple linear regression analysis was performed. RESULTS Total behavioral problems were predicted by a child temperament of more negative affectivity and less effortful control, moderated by gestational age. Internalizing behavioral problems was predicted by more negative affectivity and less effortful control moderated by male sex and associated with lower gestational age. Externalizing behavior problems was predicted by less effortful control. CONCLUSIONS The main findings of the present study showed that the high immaturity at the birth of preterm infants, associated with temperament traits of more negative affectivity and less effortful control, increase the risk for future behavioral problems.

Abstract
Preterm birth (<37 weeks' gestation) has been associated with problems in social functioning. Whether social inhibition is specifically related to preterm birth and whether early parenting may protect against social inhibition difficulties is unknown. To explore effects of gestational age and early parent-infant relationships on social inhibition, 1314 children born at 26-41 weeks gestational age were studied as part of the prospective Bavarian Longitudinal Study. Early parent-infant relationship quality was assessed postnatally with the parent-infant relationship index. Social inhibition was assessed at age 6 years using an experimental procedure, in which nonverbal and verbal responses were coded into social inhibition categories (disinhibited, normally responsive, inhibited). Multinomial logistic regressions indicated that children with lower gestational age showed more socially disinhibited (nonverbal: OR = 1.27 [95% CI = 1.17-1.40], verbal: OR = 1.23 [95% CI 1.13-1.35]) and inhibited (nonverbal: OR = 1.21 [95% CI = 1.11-1.32], verbal: OR = 1.11 [95% CI = 1.01-1.21]) responses. Good early parent-infant relationships were associated with less verbal disinhibition (OR = 0.70 [95% CI = 0.52-0.93]). Findings suggest that children with lower gestational age are at greater risk to be both socially inhibited and disinhibited. Early parenting affected risk of abnormal social responses. Supporting early parent-infant relationships may reduce preterm children's risk for social difficulties.

Abstract
STUDY OBJECTIVES We aimed to compare 2-year-old children born preterm with children born full term regarding: (1) sleep characteristics, (2) temperament, and (3) relations between sleep pattern and habits and temperament. METHODS The study included 51 preterm children with normal cognitive, language, and motor development (mean = 20.94 months, standard deviation [SD] = 4.08) and 57 full-term children (mean = 21.19, SD = 4.32). To assess sleep-related difficulties and habits and child temperament, mothers completed the following questionnaires: the (1) Sleep Disturbance Scale for Children-adapted (SDSC); (2) Brief Infant Sleep Questionnaire (BISQ); and (3) Italian Temperament Questionnaires-version 12-36 months (QUIT). RESULTS Preterm children needed less support to fall asleep and fell asleep more often alone in their own bed compared to those born at full term; however, preterm children showed more frequent sleep difficulties, such as restlessness and breathing problems during the night. In addition, preterm children had lower scores in the temperamental dimension of attention and higher scores in negative emotionality than full-term children. Finally, sleep problems were correlated with higher motor activity, lower social orientation and attention, and increased negative emotionality; a shorter nocturnal sleep duration was related to higher motor activity and lower inhibition to novelty whereas an earlier rise time was associated with lower attention and social orientation. CONCLUSIONS Preterm children showed sleep pattern problems and disturbance, predominance of attention problems, and negative emotionality related to sleep disruption.

Abstract
OBJECTIVE The aim of this study was to compare temperament and behavior profiles among groups of preterm toddlers differentiated by level of prematurity and the presence of bronchopulmonary dysplasia (BPD) or retinopathy of prematurity (ROP), controlling for neonatal clinical conditions and chronological age. METHOD The sample comprised 100 preterm toddlers segregated according to level of prematurity (75 very preterm and 25 moderate/late preterm) and presence of BPD (n=36) and ROP (n=63). Temperament was assessed by the Early Childhood Behavior Questionnaire and behavior by the Child Behavior Checklist. The MANOVA was performed with a post-hoc univariate test. RESULTS The level of prematurity and the presence of BPD and ROP did not affect temperament and behavioral problems in toddlers born preterm. However, the covariates age and length of stay in NICU (Neonatal Intensive Care Unit) affected temperament and behavioral problems, respectively. The older toddlers showed higher inhibitory control and lower activity levels than younger toddlers (range of 18-36months-old). Additionally, toddlers who stayed in the NICU longer showed more pervasive development and emotionally reactive problems than toddlers who stayed in NICU for less time. CONCLUSION The level of prematurity and the presence of bronchopulmonary dysplasia and retinopathy of prematurity did not affect temperament and behavioral problems in toddlers born preterm. However, a longer stay in the NICU increased the risk for behavioral problems, and age enhanced the regulation of temperament at toddlerhood.
