RESUMO

A central goal in the field of developmental psychopathology is to evaluate the complex, dynamic transactions occurring among biological, psychological, and broader social-cultural contexts that predict adaptive and maladaptive outcomes across ontogeny. Here, I briefly review research on the effects of a history of childhood maltreatment on parental, child, and dyadic functioning, along with more recent studies on the intergenerational transmission of trauma. Because the experience and sequelae of child maltreatment and the intergenerational transmission of trauma are embedded in complex biopsychosocial contexts, this research is best conceptualized in a developmental psychopathology framework. Moreover, there is a pressing need for investigators in this area of study to adopt dynamic, multi-level perspectives as well as using developmentally guided, sophisticated research methods. Other directions for research in this field are suggested, including the implementation of collaborative interdisciplinary team science approaches, as well as community-based participatory research, to increase representation, inclusion, and equity of community stakeholders. A greater focus on cultural and global perspectives is also recommended.

RESUMO

Infant regulatory behavior develops since birth and impacts their early social interactions. Infants differ in the relative coherence and incoherence of their cross-modal communicative signals during en-face infant-caregiver interactions. We expand this research by evaluating whether different infant regulatory patterns observed during the Face-to-Face Still-Face (FFSF) at 3 months are associated with the coherence or incoherence of infants' cross-modal communicative behaviors during en-face interactions or with multiple dimensions of mother-infant interactive behavior during free-play. Analyses were based on data collected from 100 mother-infant dyads from urban, working- and middle-class backgrounds in Portugal who were videotaped during the FFSF and free play at 3 months. Results confirm that infants' different regulatory behavior patterns in the FFSF at 3 months are associated with the coherence and incoherence of their cross-modal interactive behaviors and specific aspects of mother-infant interaction. Infants with a Social-Positive oriented regulatory pattern during the FFSF displayed more coherent and less incoherent communicative behaviors with their mothers and were more cooperative during free play. In turn, their mothers were more sensitive. Our findings support the perspective that infants' regulatory behavior strategies in the context of caregiver regulatory support and sensitivity are likely to increase dyadic correspondence and infant ability to engage with the world.

RESUMO

Mother-infant interactions form a strong basis for emotion regulation development in infants. These interactions can be affected by various factors, including maternal postnatal anxiety. Electroencephalography (EEG) hyperscanning allows for simultaneous assessment of mother-infant brain-to-behavior association during stressful events, such as the still-face paradigm (SFP). This study aimed at investigating dyadic interactive behavior and brain-to-behavior association across SFP and identifying neural correlates of mother-infant interactions in the context of maternal postnatal anxiety. We measured frontal alpha asymmetry (FAA), a physiological correlate of emotion regulation and a potential marker of risk for psychopathology. To emulate real-life interactions, EEG and behavioral data were collected from 38 mother-infant dyads during a smartphone-adapted dual-SFP. Although the behavioral data showed a clear still-face effect for the smartphone-adapted SFP, this was not reflected in the infant or maternal FAA. Brain-to-behavior data showed higher infant negative affect being associated with more infant leftward FAA during the still-face episodes. Finally, mothers with higher postnatal anxiety showed more right FAA during the first still-face episode, suggesting negative affectivity and a need to withdraw from the situation. Our results form a baseline for further research assessing the effects of maternal postnatal anxiety on infants' FAA and dyadic interactive behavior.

RESUMO

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


Un creciente cuerpo investigativo muestra que las relaciones afectivas tempranas son fundamentales para posteriores resultados de desarrollo y sicosociales de los niños. Sin embargo, los resultados son variados acerca de si el nacimiento prematuro predice la afectividad posterior, pero la inseguridad es generalmente más prevalente entre infantes bajo más alto riesgo médico y/o social/familiar. Este estudio longitudinal se propuso identificar factores específicos de predicción de la afectividad, relacionales, familiar/demográficos y perinatales en un grupo muestra de 63 infantes portugueses nacidos muy o extremadamente prematuros (VEPT, < 32 semanas gestacionales) y sus madres de diversos niveles socioeconómicos. Un tercio de las madres tenían factores de riesgo social/familiar (v.g. madre soltera, inmigrante, desempleada, de baja educación y/o de bajos recursos económicos). A los tres meses (edad corregida), se les observó a las díadas durante la interacción social en el paradigma de Cara a Cara y Rostro Inmutable (FFSF) y durante el juego libre. A los 12 meses, se les observó a las díadas madre-infante por medio de la Situación Extraña de Ainsworth. Se clasificó más de la mitad (58.7%) de los infantes como afectivamente inseguros. Entre los factores de predicción de la afectividad segura se incluyó un patrón de conducta regulatoria con orientación social positiva durante FFSF, una sensibilidad materna más alta y la cooperación del infante durante el juego libre, así como la ausencia de factores de riesgo sociales/familiares. Las variables perinatales no estuvieron relacionadas con la afectividad. Los resultados indican que los factores contextuales, tanto relacionales como sociales contribuyen a la afectividad en este grupo biológicamente vulnerable.

RESUMO

The COVID-19 pandemic and associated mitigation efforts created stress that threatened parent and child well-being. Conditions that increase stress within families heighten the likelihood of child abuse, but social support can mitigate the impact. This short-term investigation considered whether cumulative risk, COVID-19 specific risk, and emotional support (one aspect of social support), were associated with child abuse potential during the pandemic. Additionally, we investigated whether emotional support moderated the association between COVID-19 specific risk and child abuse potential, and associations between child abuse potential and emotionally positive and emotionally negative parenting. Participants included 89 parents, from a metropolitan area with a large number of economically distressed families, who completed online questionnaires. COVID-19 specific risk and emotional support each explained additional variance in child abuse potential beyond cumulative risk, but emotional support did not moderate the association between COVID-19 specific risk and child abuse potential. Consistent with expectations, child abuse potential was negatively associated with emotionally positive parenting and positively associated with emotionally negative parenting practices. Results highlight the importance of addressing both risks and supports at multiple levels for parents during times of stress.

RESUMO

Infants exhibit flexibly organized configurations of facial, vocal, affective, and motor behavior during caregiver-infant interactions that convey convergent messages about their internal states and desires. Prior work documents that greater cross-modal discrepancy at 4 months predicts disorganized attachment. Here, we evaluated whether: very preterm (VPT) or full-term (FT) status predicts cross-modal coherence or incoherence in infants' behavior with the caregiver at 3 months; and, regardless of prematurity, whether cross-modal interactive coherence or incoherence predicts 12-month attachment. Participants included 155 infants (85 FT; 70 VPT), and their mothers followed from birth to 12 months (corrected age). Infants' cross-modal coherent and incoherent responses were scored microanalytically from videotaped en-face interactions. Infants' attachment security was evaluated during Ainsworth's Strange Situation. Infants born VPT exhibited more incoherent cross-modal responses and insecure attachment than infants born FT. Regardless of prematurity, infants' coherent and incoherent cross-modal interactive behaviors at 3 months predicted different attachment patterns at 12 months.

RESUMO

Few studies have examined whether maternal caregiving representations are associated with maternal reflective functioning (MRF), especially when MRF is evaluated longitudinally beginning in pregnancy. This study addresses this gap by evaluating whether prenatal and postnatal MRF are associated with mothers' caregiving representations assessed at 7 months postpartum, and by exploring theoretically unexpected MRF scores in each of the representational categories. Forty-seven mothers were recruited during their last trimester of pregnancy from an obstetrics clinic at a university hospital located in a large mid-western city in the United States. During pregnancy, mothers completed the Pregnancy Interview, and at 7 months postpartum they completed the Parent Development Interview (PDI) and the Working Model of the Child Interview. Results indicate that higher prenatal and postnatal MRF increased the odds of being classified as balanced versus disengaged. At 7 months, MRF also increased the odds of being balanced vs. distorted. Ten mothers who were classified as balanced or distorted had unexpected prenatal MRF scores, and six mothers had unexpected MRF scores when representations were assessed concurrently. Mothers classified as balanced with low MRF scores tended to have a low level of education, whereas mothers classified as distorted with high MRF scores had responses that were hostile, helpless, and role-reversed.


Pocos estudios han examinado el hecho de si las representaciones maternas acerca del cuidado están asociadas con el funcionamiento reflexivo materno (MRF), especialmente cuando MRF se evalúa longitudinalmente comenzando en el embarazo. Este estudio aborda este vacío por medio de evaluar si el MRF prenatal y postnatal está asociado con las representaciones que las madres tienen de prestar el cuidado evaluadas a los 7 meses después del parto, y por medio de explorar teoréticamente los puntajes no esperados de MRF en cada categoría representativa. Se reclutaron cuarenta y siete madres durante su último trimestre de embarazo del hospital de una universidad localizado en una ciudad del medio oeste de los Estados Unidos. Durante el embarazo, las madres completaron la Entrevista de Embarazo y a los 7 meses después del parto ellas completaron la Entrevista del Desarrollo del Progenitor y el Modelo de Trabajo de la Entrevista del Niño. Los resultados indican que el más alto MRF prenatal y postnatal también aumentó las posibilidades de ser clasificada como equilibrada vs. indiferente. A los 7 meses, el MRF también aumentó las posibilidades de ser equilibrada vs. distorsionada. Diez madres a quienes se les clasificó como equilibradas o distorsionadas tuvieron puntajes de MRF prenatales no esperados, y seis madres tuvieron no esperados puntajes de MRF cuando las representaciones fueron evaluadas al mismo tiempo. Las madres a quienes se les clasificó como equilibradas con bajos puntajes de MRF tendían a tener un nivel bajo de educación, mientras que las madres a quienes se les clasificó como distorsionadas con puntajes altos de MRF tuvieron respuestas que eran hostiles, indefensas y de inversión de papeles.


Peu d'études ont examiné si les représentations du soin maternel sont liées au fonctionnement réflectif maternel (abrégé ici selon l'anglais maternal reflective functioning, soit MRF), surtout lorsque le MRF est évalué de manière longitudinale à commencer par la grossesse. Cette étude porte sur cet écart en évaluant si le MRF prénatal et postnatal est lié aux représentations du soin des mères évalué à 7 mois postpartum, et en explorant des scores MRF théoriquement inattendus dans chacune des catégories représentationnelles. Quarante-sept mères ont été recrutées durant leur dernier trimestre de grossesse dans un CHU situé dans une grande ville du centre des Etats-Unis. Durant la grossesse les mères ont passé l'Entretien de Grossesse et à 7 mois postpartum elles ont passé l'Entretien du Développement du Parent et le Modèle de Travail de l'Entretien de l'Enfant. Les résultats indiquent qu'un MRF prénatal et postnatal élevé augmentait les chances d'être classé comme équilibrée par rapport à désengagée. A 7 mois, le MRF augmentait aussi les chances d'être équilibrée par rapport à faussée. Dix mères qui ont été classées comme étant équilibrées ou faussées avaient des scores de MRF prénatal inattendus et six mères avaient des scores de MRF inattendu quand les représentations étaient évaluées en même temps. Les mères classées comme équilibrées avec des scores de MRF bas tendaient à avoir un niveau d'éducation plus bas, alors que les mères classées comme faussées avec des scores de MRF élevés ont fait preuve de réactions qui étaient hostiles, désemparées et de rôle inversé.

RESUMO

Remote schooling due to Coronavirus Disease 2019 (COVID-19) created profound challenges for families. In this investigation, we examined parents' depression and anxiety during remote schooling and their associations with parents' reports of school support. We also evaluated indirect and interactive (i.e., moderation) associations. Participants were parents (N = 152, 92.8% mothers, 65.1% Black) from an urban area with high rates of COVID-19. Of the 152 parents, 27.6% reported elevated levels of depression and 34.2% reported elevated anxiety. Regression analyses showed that school support was negatively associated with parents' depression (ß = -.33, p < .01) and anxiety (ß = -.21, p < .01). There was an indirect association between school support and parents' mental health via household chaos and daily routines. Reported COVID-19 impact moderated the direct association between school support and parental depression and anxiety. There was a statistically significant association between school support and parents' depression and anxiety when COVID-19 impact was low or moderate, but not when COVID-19 impact was high. These results may suggest that for parents who were not highly impacted by the pandemic, school support buffered the association between stress and parents' mental health problems; parents most impacted by COVID-19 may need additional support.

RESUMO

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

RESUMO

OBJECTIVE: The study examined whether mother-child reciprocity across increasingly challenging contexts moderated the association between household chaos and early childhood behavior problems. BACKGROUND: Living in a chaotic household is associated with behavioral dysregulation in childhood. An important goal in discordant household contexts is to establish positive aspects of relationships that are associated with more favorable developmental outcomes. METHOD: The study analyzed data from 127 mother-child dyads participating in the 3-year visit in a study of primarily low-income, African American/Black families in urban areas. Dyads were videotaped during three successive, increasingly challenging, interaction tasks. Multiple regression analyses examined household chaos, dyadic reciprocity, and the interplay of those as predictors of behavior problems. RESULTS: Greater household chaos was associated with more internalizing and externalizing behavior problems. Moderation analyses indicated that dyadic reciprocity during two challenging interaction tasks (but not during free play) attenuated the association between household chaos and internalizing problems. CONCLUSIONS: Household chaos was not associated with internalizing problems among dyads who had a connected, supportive relationship in more challenging interactive contexts. IMPLICATIONS: Improving shared positive affect and dyadic harmony in the parent-child relationship may help protect young children against the negative influence of chaotic contexts.

RESUMO

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

RESUMO

Prior research described three stable patterns of organized behavior employed by infants to manage stressful interactive situations with their mothers in the Face-to-Face Still-Face paradigm (FFSF) at 3 and 9 months postpartum.  The current longitudinal study expands this research by examining the extent to which these patterns predict infants' later attachment quality. For that purpose, 108 full-term infants and their mothers participated in the FFSF at 3 and 9 months, and in the Strange Situation at 12 months. Cross-tabulation analyses indicated a significant association between (1) the Social-positive oriented pattern and secure attachment, (2) the Distressed-inconsolable pattern and insecure-ambivalent attachment, and (3) the Self-comfort oriented pattern and insecure-avoidant attachment. Our results contribute to a growing body of studies suggesting that patterns of infants' regulatory behavior assessed during the FFSF during the first year, may be early developmental precursors of attachment patterns at 12 months.

RESUMO

Prior research in Western countries (mostly the US, Canada and northern Europe) indicates that mothers' representations are associated with mother-infant interaction quality and their child's attachment security later in the first year. Fewer studies, however, have evaluated whether these associations hold for mother-infant dyads in other countries, such as Brazil and Portugal. Although these countries share a similar language and culture, they differ on societal dimensions that may affect parenting attitudes and mother-infant relationships, such as economic stress, social organisation, social policy, and the availability of services for young families. In this longitudinal study, we followed two independent samples of Brazilian and Portuguese mother-infant dyads from the perinatal period to 12 months post-partum. We assessed mothers' perinatal representations using semi-structured interviews in the first 48 hours after the infant's birth, and evaluated the associations of these representations with mother interaction quality at 9 months and infant attachment at 12 months. Results were similar in each country, corroborating prior research in single Western countries: Mothers with more positive perinatal representations were more sensitive to their infants during free play at 9 months and were more likely to have infants classified as securely attached at 12 months.

RESUMO

This study describes maternal and infant contributions to dyadic affective exchanges during the Still-Face Paradigm (SFP) in an understudied mostly low-income sample. One hundred eleven mothers and their 7-month-old infants were videotaped during the SFP to analyze how a social stressor affects mother-infant positive and negative affective exchanges during interaction. The SFP includes 3 episodes: baseline, maternal still-face, and reunion. Maternal and infant positive and negative affect were scored by masked reliable coders. Data were analyzed using the Actor-Partner Interdependence Model to test the hypotheses that each partner's affectivity during the baseline episode would predict their own affectivity during the reunion episode (actor effects). We also expected that each partner's affectivity during the baseline episode would influence the other partner's affectivity during the reunion episodes (partner effects). After controlling for infant sex and maternal education, results provided evidence for actor effects for maternal and infant positive affect, and for partner effects for maternal baseline positive affect to infant positive affect during the reunion. One significant partner effect was observed for negative affect: Infant negativity during baseline predicted greater maternal negativity during reunion. Findings confirm that both mothers and infants contribute to dyadic affective processes during the SFP but specific findings vary depending on the affective valence in question. Clinical implications and future research are discussed.

RESUMO

Maternal oxytocin is connected to aspects of parenting including sensitivity, warmth, positive affect, and affectionate touch. Oxytocin receptor gene (OXTR) polymorphisms are associated with circulating oxytocin levels, altered brain activity, and parenting behaviors. This study aimed to replicate prior work on OXTR single-nucleotide polymorphisms (SNPs) rs1042778 and rs53576 in relation to maternal sensitivity, explore associations with other aspects of parenting (i.e., negative parenting), evaluate observational and self-report measures of parenting in relation to OXTR SNPs, and examine whether childhood trauma exposure moderates the relation between OXTR SNPs and parenting. Mothers (N = 100) were observed during 2 teaching interaction tasks with their 7-month-old infant, completed questionnaire and interview measures related to parenting and trauma history, and provided saliva specimens to derive OXTR genotypes. Mothers with OXTR rs1042778 TT genotypes demonstrated lower behavioral sensitivity, lower engagement, higher intrusiveness, and more frequent frightened/frightening behavior than mothers with TG or GG genotypes. Genotype interacted with childhood trauma history such that mothers who had experienced childhood trauma were more likely to demonstrate frightened/frightening behavior if they had the TT genotype on rs1042778 relative to the TG or GG genotype; however, small cell sizes for this interaction suggest replication is warranted. Contrary to expectations, mothers with the TT genotype on rs1042778 self-reported that they had less impaired bonding than mothers with TG or GG genotypes. Results are discussed with respect to prior work with oxytocin in lower versus higher risk samples, and the potential role of mothers' self-awareness in explaining discrepancies between results from observational versus self-report measures of parenting.

RESUMO

The current study addressed two aims: (1) to describe different patterns of infant regulatory behavior during the Face-to-Face Still-Face (FFSF) paradigm at 3 months of age and (2) to identify specific, independent predictors of these patterns from an a priori set of demographic, infant (e.g., temperament), and maternal (e.g., sensitivity) variables. Analyses were based on data collected for 121 mother-infant dyads assessed longitudinally in the newborn period and again at 3 months. In the newborn period, infants' neurobehavior was evaluated using the Neonatal Behavioral Assessment Scale (NBAS) and mothers reported on their caregiving confidence and their newborns' irritability and alertness. At 3 months, mothers reported on their infant's temperament, and mother-infant interactions were videotaped during free play and the FFSF. Three patterns of infant regulatory behavior were observed. The most common was a Social-Positive Oriented Pattern, followed by a Distressed-Inconsolable Pattern, and a Self-Comfort Oriented Pattern. Results of multinomial logistic regression indicated that categorical assignment was not associated with demographic or infant characteristics, but rather with dyadic regulatory processes in which maternal reparatory sensitivity played a crucial role.

RESUMO

This study examined the stability of three patterns of infant regulatory behavior identified in the face-to-face still-face (FFSF) paradigm at 3 and 9 months-social-positive oriented, distressed-inconsolable, and self-comfort oriented-and whether variations in infants' heart-rate were correlated with them. Although some studies have examined the stability of discrete infant behaviors, none have investigated the stability of early regulatory patterns across FFSF episodes over time. Healthy full-term infants and their mothers (N = 112) were videotaped in the FFSF when infants were 3 and 9 months old. Infants' regulatory patterns were scored with the Coding System for Regulatory Patterns in the FFSF. Infants' heart-rate level during each episode of the FFSF was also assessed. The social-positive-oriented pattern was the most prevalent at both ages. Cross-tabulation analysis showed a robust stability (Cohen's κ = .72) of the regulatory patterns from 3 to 9 months. The heart-rate level of infants with a social-positive-oriented pattern at 3 and 9 months showed recovery to baseline levels following the still-face. In contrast, the heart-rate level of infants with a distressed-inconsolable pattern at 9 months increased from the still-face to the reunion episode, whereas the heart-rate level of infants with a self-comfort-oriented pattern at 9 months did not change from the still-face to the reunion episodes. These results suggest that infants exhibit distinct organized regulatory patterns as early as 3 months that are stable over a 6-month interval and associated with variations in infants' physiological responses across FFSF episodes at both ages.

RESUMO

The Neonatal Behavioral Assessment Scale (NBAS) is a widely used in the neurobehavioral assessment of neonates in clinical practice and research. Lester's data reduction system for the NBAS items is the most often used in research, but the few factor analytic studies carried out with it leave gaps in its validation. The current study aimed to test and compare (a) the factorial structure of the Lester's data reduction system for the NBAS and (b) an alternative data reduction system, slightly modified from Lester's system. The NBAS was administered to 196 healthy Portuguese full-term infants (51% male) in the first 72 h of life (M = 43.63 h). Construct validity of the data reduction systems was tested through confirmatory factor analysis (CFA). Lester's original system was compared to three alternative models, two of which included a revision of the scoring rules for three items and the exclusion of five items. The CFA generally supported the six-factor structure. However, fit indices for Lester's original model were only fair. An alternative, revised model with a second-order factor - Self-Organizing System - demonstrated a better fit. The results provide evidence to support a modified form of Lester's six behavioral clusters as a data reduction model for the NBAS items.

RESUMO

Functional circuits of the human brain emerge and change dramatically over the second half of gestation. It is possible that variation in neural functional system connectivity in utero predicts individual differences in infant behavioral development, but this possibility has yet to be examined. The current study examines the association between fetal sensorimotor brain system functional connectivity and infant postnatal motor ability. Resting-state functional connectivity data was obtained in 96 healthy human fetuses during the second and third trimesters of pregnancy. Infant motor ability was measured 7 months after birth using the Bayley Scales of Infant Development. Increased connectivity between the emerging motor network and regions of the prefrontal cortex, temporal lobes, posterior cingulate, and supplementary motor regions was observed in infants that showed more mature motor functions. In addition, females demonstrated stronger fetal-brain to infant-behavior associations. These observations extend prior longitudinal research back into prenatal brain development and raise exciting new ideas about the advent of risk and the ontogeny of early sex differences.

RESUMO

The current study evaluated whether maternal insightfulness can buffer the negative influence of postpartum stressful life events on maternal parenting behaviors. Participants were 125 mother-infant dyads (55% boys) who present a subsample of a larger longitudinal study on maternal maltreatment during childhood and its impact on peripartum maternal adjustment. Women were primarily white and middle class. At 4 months postpartum, mothers reported on the stressful life events experienced after the child's birth and current depressive symptoms. At 6 months postpartum, maternal parenting quality was assessed using videotaped mother-infant interactions and maternal insightfulness was evaluated using the Insightfulness Assessment. Insightfulness significantly moderated the effect of postpartum stressful events on maternal parenting behaviors. Mothers who were insightful displayed high levels of positive parenting during interactions with their infant regardless of the amount of stressful life events experienced. In contrast, mothers classified as non-insightful showed less positive parenting as they experienced more stressful life events. Findings highlight the protective role of maternal insightfulness in the face of postpartum stress, and suggest that efforts to enhance insightfulness during the early postpartum period may be particularly relevant for women in high-risk contexts.
