Prenatal maternal depression predicts neural maturation and negative emotion in infants

Despite widespread acceptance that prenatal symptoms of depression in mothers are detrimental to infants’ long-term emotional and cognitive development, little is known about the mechanisms that may integrate outcomes across these domains. Rooted in the integrative perspective that emotional development is grounded in developing cognitive processes, we hypothesized that prenatal symptoms of depression in mothers would be associated with delays in neural maturation that support sociocognitive function in infants, leading to more problematic behaviors. We used a prospective longitudinal study of mothers (N = 92) and their infants to test whether self-reported symptoms of depression in mothers during the second and third trimesters were associated with neural development and infant outcomes at 4 months of age. While controlling for postpartum symptoms of depression, more prenatal symptoms of depression in mothers predicted less neural maturation in the parietal region of 4-month-old infants. Less neural maturation, in turn, was associated with greater infant negativity, suggesting neural maturation as a putative mechanism linking maternal symptoms of depression with infant outcomes. Differences in neural regions and developmental timing are also discussed.     

Attachment representations in mothers of preterm infants

The aim of the study was to assess attachment representations in mothers of preterm infants using the Working Model of Child Interview (WMCI) at the 12 months of the infant's corrected age. In addition, the relation between WMCI representation categories and the Edinburgh Postnatal Depression Scale score at 6 months of the infant's corrected age was studied. There were 38 mothers of preterm infants (<1500 g or <32 gestational weeks) and 45 mothers of full-term infants. The results showed no differences between the study groups in the distribution of the three main representation categories (balanced, disengaged and distorted). However, there were qualitative differences in representations between the groups. Furthermore, maternal depression symptoms were associated with distorted representation category. We suggest that despite the qualitative differences in the mothers’ representations, mothers of preterm infants are as likely to form balanced attachments with their infants as mothers of full-term infants.     

Depression in the early postpartum period and attachment to children—in mothers of NICU infants

Depression in early puerperium was evaluated in terms of maternal attachment in mothers of children admitted to the neonatal intensive care unit (NICU) in comparison to a control group of mothers of full‐term infants. A survey including Zung's self‐rating depression scale (ZSDS), a postpartum maternal attachment scale and items addressing the mother's feelings and peripheral conditions was conducted on mothers of children admitted to the NICU. Among the 153 mothers who gave valid responses, positive ZSDS scores of over 40 were seen in 61.8%. In terms of the children's disorder, strong depressive tendency was noted among mothers of low birth weight infants. Significant correlation was noted between the ZSDS and the ‘core maternal attachment’ (negative correlation) and ‘anxiety regarding children’ (positive correlation) subscales of postpartum maternal attachment. Path analysis revealed the father's positive reaction in learning of the pregnancy resulted in elevation of the ‘core maternal attachment’ score, in contrast to the control group mothers.

Interpersonal attachment predicts identification with groups

We propose a model documenting the relationship between interpersonal attachment style and identification with groups. We hypothesized that following threat to a romantic interpersonal relationship higher attachment anxiety would be associated with lowered tendencies to identify with groups. In two studies using varied social groups we observed support for this hypothesis. In Experiment 1 we found that participants higher in attachment anxiety identified less with a salient ingroup after imagining a distressing argument with their romantic partner. In Experiment 2 we replicated these findings using an implicit measure of social identification and additionally observed a moderating role for attachment avoidance. We discuss the implications of these findings for theoretical models of interpersonal attachment and social identification.     

Maternal touch in caregiving behavior of mothers with and without postpartum depression

The way a mother touches her infant plays a central role in maternal caregiving behavior. Thus, the purpose of the present study was to examine associations between touch and positive and negative caregiving behavior and whether this association differed in mothers with and without postpartum depression, an episode of depressive disorder following childbirth. Positive caregiving behavior was operationalized as sensitive behavior, i.e. the mother’s ability to notice the child’s signals, interpret these signals correctly and respond to them promptly and appropriately. Negative caregiving behavior was operationalized as overriding behavior, i.e. behavior which disturbs the child’s behavior or redirects the child’s attention to follow the parent’s agenda. Seventy mother-infant dyads (44 in the nonclinical group and 26 in the clinical group) participated in a 10 minutes long mother-infant interaction at four months postpartum. The sample is part of an archival dataset of a longitudinal study investigating the parent-child relationship and child development. Three minutes of the interaction were coded a) microanalytically for touch, using a modified version of the Maternal Touch Scale (Beebe et al., 2010), and b) macroanalytically for sensitive and overriding behavior, using the Coding Interactive Behavior measure (Feldman, 1998). Hierarchical regression analyses with bootstrapping showed that caregiving touch, but not affectionate and static touch, was associated with sensitive behavior across the whole sample. Moreover, playful, but not rough-intrusive touch, was associated with overriding behavior across the whole sample. Associations did not differ between mothers with and without postpartum depression.     

Latina Immigrant Victims of Interpersonal Violence in New Jersey: A Needs Assessment Study

Recent studies have stressed the seriousness of male-female intimate partner violence (MFIPV) suffered by Latina women and the need for more comprehensive and culturally sensitive services for this population. This article provides an overall understanding of the type and severity of abuse suffered by examining Latina victims in New Jersey, a state that has a remarkably diverse and numerous Latino population. Socio-economic and residence statuses are considered, and self-help seeking behaviors and the challenges of women's social isolation are addressed. In addition, risk factors related to MFIPV, such as substance abuse and witnessed/experienced violence in childhood, are explored. The understanding of these characteristics and risk factors are critical to the design of prevention and intervention programs.     

The relationship between adult attachment and depression in Korean mothers during the first 2 years postpartum: A moderated mediation model of self-esteem and maternal efficacy

This study examined a possible pathway to better understand the relationships between attachment schema and maternal depression through self-esteem and maternal self-efficacy. Questionnaires regarding attachment style, self-esteem, maternal self-efficacy, and depression were completed by 176 mothers who visited paediatrics centres. The results showed that self-esteem fully mediated the relationship between preoccupied attachment and maternal depression and partially mediated the association between fearful attachment and maternal depression. The mediating effects of self-esteem in the relationship between insecure attachments (preoccupied and fearful types) were moderated by the mother’s parenting efficacy. More specifically, mothers with high maternal efficacy (scores ⩾ 32, upper 10th percentile) were protected from the detrimental impact of attachment insecurity and low self-esteem on maternal depression, compared with mothers with low parenting-efficacy. Maternal depression benefits from intervention targeting the mother’s parenting efficacy.     

Temperamental precursors of infant attachment with mothers and fathers

The degree to which parent sensitivity and infant temperament distinguish attachment classification was examined. Multilevel modeling was used to assess the effect of parent sensitivity and infant temperament on infant–mother and infant–father attachment. Data were collected from mothers, fathers, and their infants (N = 135) when the infant was 3-, 5-, 7-, 12-, and 14-months old. Temperament was measured using the Infant Behavior Questionnaire-Revised ( Gartstein & Rothbart, 2003); parent sensitivity was coded during the Still Face Paradigm ( Tronick, Als, Adamson, Wise, & Brazelton, 1978); attachment was coded using the Strange Situation ( Ainsworth, Blehar, Waters, & Wall, 1978). Results indicate that mothers and fathers were less sensitive with insecure-avoidant infants. Whereas only one difference was found for infant–mother attachment groups and temperament, five significant differences emerged for infant–father attachment groups, with the majority involving insecure-ambivalent attachment. Infants classified as ambivalent with fathers were higher in perceptual sensitivity and cuddliness and these infants also showed a greater increase in low-intensity pleasure over time compared with other infants. Results indicate the importance of both parent sensitivity and infant temperament, though operating in somewhat different ways, in the development of the infant–mother and infant–father attachment relationship.     

Patterns of maternal responding in postpartum mothers with schizophrenia

Little is known about how schizophrenia might affect how a mother responds to her infant, such as whether responding is reduced or impaired. The aim was to identify, from brief videotaped interactions, whether the responses of mothers with schizophrenia were fewer, less positive, more negative, and more ‘abnormal’ than mothers with affective disorder, and whether their infants (mean age: 15 weeks) lacked activity or initiation to which mothers could respond. Mothers with schizophrenia (N = 14) were as responsive as mothers with affective disorder (N = 31), but they showed markedly low positive responsiveness. Only the schizophrenia group exhibited non-responses as a result of being psychologically withdrawn from the interaction, and abnormal behaviors. Inconsistent to our hypothesis, infants in both groups showed similar levels of activity, initiative and negativity. The findings highlight the need for further research to examine the contribution of maternal response impairments to the developmental vulnerability of this genetically high-risk group.     

Goodness of fit between prenatal maternal sleep and infant sleep: Associations with maternal depression and attachment security

The current study prospectively examined the ways in which goodness of fit between maternal and infant sleep contributes to maternal depressive symptoms and the mother-child relationship across the first years of life. In a sample of 173 mother-child dyads, maternal prenatal sleep, infant sleep, maternal depressive symptoms, and mother-child attachment security were assessed via self-report, actigraphy, and observational measures. Results suggested that a poor fit between mothers’ prenatal sleep and infants’ sleep at 8 months (measured by sleep diary and actigraphy) was associated with maternal depressive symptoms at 15 months. Additionally, maternal depression mediated the association between the interplay of mother and infant sleep (measured by sleep diary) and mother-child attachment security at 30 months. Findings emphasize the importance of the match between mother and infant sleep on maternal wellbeing and mother-child relationships and highlight the role of mothers’ perceptions of infant sleep.     

Maternal depression and dyadic interaction: the role of maternal attachment style

Maternal mental health and the contents of her representational world are important determinants of early parent–child relationship. We examined, first, the role of prenatal and postnatal depressive symptoms and maternal attachment style in predicting the quality of mother–child interaction. Second, we analysed whether the secure‐autonomous attachment style can protect the dyadic interaction from the negative effects of maternal depression. The participants were 59 mother–infant pairs examined during pregnancy (T1), 4–5 months postpartum (T2) and when the children were approximately 14 months old (T3). Maternal attachment style was assessed with a modified Adult Attachment Interview ‐procedure, depressive symptoms with Edinburgh Postnatal Depression Scale, and observed mother–child interaction with Care Index. The results show that autonomous mothers were more sensitive and responsive and their children more co‐operative than dyads with dismissing maternal attachment style. As hypothesized, mothers with the combination of both prenatal and postpartum depressive symptoms were highly unresponsive in their dyadic interaction. Further, prenatal depressive symptoms had a stronger impact on maternal unresponsiveness than postnatal symptoms. As hypothesized, mother's autonomous attachment style protected the mother–child interaction from the negative impact of maternal postnatal depressive symptoms, whereas dyads with preoccupied mothers were especially at risk for interaction problems when mothers had postpartum depressive symptoms.

Recruiting and Assessing Recent Young Adult Latina Immigrants in Health Disparities Research

The authors interviewed 4 researchers to identify facilitators in recruiting and assessing Latina immigrants. The 4 researchers recruited 530 recent Latina immigrants (ages 18–23 years) for a study of social and cultural determinants of health. Consensual qualitative research methods revealed that respondent‐driven sampling was an effective recruitment method. Fear of deportation was a barrier. Stigma about sensitive topics (e.g., sex, drug use) did not affect participation. Findings can help counselors conduct health disparities research. Los autores entrevistaron a 4 investigadores para identificar facilitadores para el reclutamiento y evaluación de inmigrantes latinas. Los 4 investigadores reclutaron a 530 mujeres latinas que habían inmigrado recientemente (edades entre 18 y 23 años) para un estudio de los factores sociales y culturales determinantes de la salud. Los métodos de investigación cuantitativa consensuados revelaron que el muestreo dirigido por las encuestadas fue un método efectivo de reclutamiento. El miedo a la deportación fue un obstáculo. El estigma asociado a temas delicados (p. ej., el sexo, el uso de drogas) no afectó a la participación. Los hallazgos pueden ayudar a los consejeros a realizar estudios sobre disparidades en la salud.     

催产素对产后抑郁症患者母性行为的调节作用

产后抑郁症是指女性分娩后一段时间内出现的严重抑郁发作现象。研究表明, 催产素不仅参与分娩过程和正常的母性行为表达, 也在调节产后抑郁的发病及患者的母性行为中起到了重要的作用。产后抑郁症患者的情绪和认知功能受损, 这可能导致了母性行为表达质量的下降; 催产素可以通过中脑边缘多巴胺系统来调控母性行为, 作用于内侧视前区(MPOA)来激活中脑腹侧被盖区(VTA)-伏隔核(NAc)环路从而影响伏隔核内多巴胺的分泌; 催产素对产后抑郁症中母性行为的调节机制可能是通过调节五羟色胺系统的功能来发挥抗焦虑作用, 也可能是通过与其它激素的交互作用来加速母性行为的表达。未来研究进一步明确催产素在中枢神经环路中的功能差异, 以及社会支持对产后抑郁症患者催产素的使用带来的影响。     

An associative learning deficit in 1-year-old infants of depressed mothers: role of depression duration

The effectiveness of infant-directed speech (IDS) produced by non-depressed mothers for promoting the acquisition of voice-face associations was investigated in 1-year-old children of depressed mothers in a conditioned-attention paradigm. Prior research suggested that infants of mothers with comparatively longer-duration depressive episodes exhibit poorer learning in response to non-depressed mothers’ IDS, but duration of depression was confounded with infant age. In the current study, 1-year-old infants of currently depressed mothers with relatively longer-duration depressive episodes (i.e., perinatal onset) showed significantly poorer learning than 1-year-olds of currently depressed mothers with relatively shorter duration depressive episodes (non-perinatal onset). This was true despite the fact that there were no measurable differences in the severity of depression, level of social functioning, or antidepressant medication use between the two groups. These findings add support to the hypothesis that there is an experience-based change in responsiveness to female IDS in infants of depressed mothers during the first year of life.     

Parent mind-mindedness,sensitivity, and infant affect: Implications for attachment with mothers and fathers

Previous research examining links between parenting and attachment has focused on behavioral aspects of parenting such as sensitivity. However, by assessing how parents reflect on infants’ mental states (mind-mindedness) we gain a broader understanding of parenting and how it impacts attachment. Mothers, fathers, and their infants (N = 135) participated in the Still Face Paradigm (SFP) at 3-, 5-, and 7- months of age, and the Strange Situation with mothers at 12 months and fathers at 14 months. Parent sensitivity and infant affect were coded from the SFP and all videos were transcribed and later coded for parents’ use of appropriate and non-attuned mind-mindedness toward their infants. Attachment with each parent was coded from the Strange Situation. Mixed effects models examined trajectories of parents’ mind-mindedness in relation to parent sensitivity and infant affect across attachment groups. Significant differences between parent gender and attachment category were detected. Specifically, parents who were less sensitive were also less mind-minded toward insecure-avoidant infants; parents used more non-attuned mind-mindedness when infants had higher negative affect. Findings suggest that, in addition to parent sensitivity, parents’ use of appropriate and non-attuned mind-mindedness during a parent-infant interaction provides insight into the developing attachment relationship for mothers and fathers.     

Social referencing in infants of mothers with symptoms of depression

The present study examined the acquisition of social referencing skills in infants of mothers with symptoms of depression (n = 44). We aimed to determine if a short discrimination training could facilitate infants’ social referencing. Mothers were instructed to pose either joyful or fearful facial expressions to cue infants’ approach/avoidance responses toward an ambiguous object. Maternal expressions were correlated with pleasant or unpleasant events occurring after the infant's response. The results showed that after the intervention, infants looked at their mothers more frequently and reached or avoided the ambiguous object based on the preceding maternal expression. The results suggest that discrimination training procedures can establish social referencing in infants of mothers with symptoms of depression.     

Motor activity and spatial proximity: Relationships to infant emotions and maternal postpartum depression

The ability to express emotions is a protective factor for infant development. Despite the multimodal nature of emotion expression, research has mainly focused on facial expressions of emotions. The present study examined motor activity and spatial proximity in relation to positive and negative infant facial expressions and maternal postpartum depression during face-to-face interactions at four months. Video cameras and a motion capture system recorded mother-infant interactions. Repeated measures ANOVAs were conducted to analyze the effect of micro-coded infant positive and negative facial affect and maternal depression diagnosis on automatically extracted measures of motor activity and spatial proximity, including speed of mothers’ arm movements (nondepressed = 32; PPD = 16), and infants’ arm movements (nondepressed = 29; PPD = 17), and head distance (nondepressed = 45; PPD = 27). Results showed that the speed of infants’ arm movements and head distance were greater during negative compared to positive infant affect. Further, the results demonstrated that the speed of PPD mothers’ arm movements was slower than the speed of nondepressed mothers’ arm movements. In the discussion, it is suggested that increased speed of infant arm movements during negative affect functions to elicit faster caregiving responses, and that increased head distance during negative infant affect functions to decrease the intensity of the interaction. Finally, the slower speed of arm movements in PPD mothers suggests psychomotor retardation, which is proposed to limit these mothers’ abilities to engage their infants during the interaction.     

Postpartum depression and infant-mother attachment security at one year: The impact of co-morbid maternal personality disorders

Previous studies on effects of postpartum depression (PPD) on infant-mother attachment have been divergent. This may be due to not taking into account the effects of stable difficulties not specific for depression, such as maternal personality disorder (PD).Mothers (N = 80) were recruited for a longitudinal study either during pregnancy (comparison group) or eight weeks postpartum (clinical group). Infants of mothers with depressive symptoms only or in combination with a PD diagnosis were compared with infants of mothers with no psychopathology. Depression and PD were assessed using self-report and clinical interviews. Infant-mother attachment was assessed when infants were 13 months using Strange Situation Procedure (SSP). Attachment (in)security was calculated as a continuous score based on the four interactive behavioral scales of the SSP, and the conventional scale for attachment disorganization was used.PPD was associated with attachment insecurity only if the mother also had a PD diagnosis. Infants of PPD mothers without co-morbid PD did not differ from infants of mothers with no psychopathology. These results suggest that co-existing PD may be crucial in understanding how PPD impacts on parenting and infant social-emotional development. Stable underlying factors may magnify or buffer effects of PPD on parenting and child outcomes.     

Associations between symptoms of maternal postpartum depression,gestational age and infant social withdrawal: A longitudinal study in a community cohort

Infant social withdrawal is a risk factor for non-optimal child development; thus, it is important to identify risk factors associated with withdrawal. In a large community sample (N = 19,017), we investigate whether symptoms of maternal and partner postpartum depression (PPD; measured with the Edinburgh Postnatal Depression Scale) and prematurity are predictors of infant social withdrawal (measured with the Alarm Distress Baby Scale). Withdrawal was assessed at 2–3, 4–7 and 8–12 months postpartum. Linear regressions showed that prematurity predicted higher infant social withdrawal at all time points, and maternal symptoms of PPD were positively associated with withdrawal at 2–3 months. Logistic regressions showed that odds for elevated social withdrawal were increased with elevated levels of maternal symptoms of PPD at 2–3 and 8–12 months. Partner's symptoms of PPD were not associated with withdrawal. Future studies should investigate how PPD symptoms and prematurity may impact the individual development of social withdrawal.
