Maternal postpartum depression is a risk factor for infant emotional variability at 4 months

Maternal postpartum depression (PPD) is a risk for disruption of mother–infant interaction. Infants of depressed mothers have been found to display less positive, more negative, and neutral affect. Other studies have found that infants of mothers with PPD inhibit both positive and negative affect. In a sample of 28 infants of mothers with PPD and 52 infants of nonclinical mothers, we examined the role of PPD diagnosis and symptoms for infants’ emotional variability, measured as facial expressions, vocal protest, and gaze using microanalysis, during a mother–infant face-to-face interaction. PPD symptoms and diagnosis were associated with (a) infants displaying fewer high negative, but more neutral/interest facial affect events, and (b) fewer gaze off events.  PPD diagnosis, but not symptoms, was associated with less infant vocal protest. Total duration of seconds of infant facial affective displays and gaze off was not related to PPD diagnosis or symptoms, suggesting that when infants of depressed mothers display high negative facial affect or gaze off, these expressions are more sustained, indicating lower infant ability to calm down and re-engage, interpreted as a disturbance in self-regulation. The findings highlight the importance of not only examining durations, but also frequencies, as the latter may inform infant emotional variability.     

Effects of maternal postpartum depression in a well‐resourced sample: Early concurrent and long‐term effects on infant cognitive,language, and motor development

This study examined early and long‐term effects of maternal postpartum depression on cognitive, language, and motor development in infants of clinically depressed mothers. Participants were 83 mothers and their full‐term born children from the urban region of Copenhagen, Denmark. Of this group, 28 mothers were diagnosed with postnatal depression three to four months postpartum in a diagnostic interview. Cognitive, language, and motor development was assessed with the Bayley Scales of Infant and Toddler Development third edition, when the infants were 4 and 13 months of age. We found that maternal postpartum depression was associated with poorer cognitive development at infant age four months, the effect size being large (Cohen's d = 0.8) and with similar effects for boys and girls. At 13 months of age infants of clinical mothers did not differ from infants of non‐clinical mothers. At this time most (79%) of the clinical mothers were no longer, or not again, depressed. These results may indicate that maternal depression can have an acute, concurrent effect on infant cognitive development as early as at four months postpartum. At the same time, in the absence of other risk factors, this effect may not be enduring. The main weaknesses of the study include the relatively small sample size and that depression scores were only available for 35 of the non‐clinical mothers at 13 months.     

Perinatal depression influences on infant negative affectivity: Timing,severity, and co-morbid anxiety

Accumulating evidence suggests that antenatal depression predicts infants’ negative affectivity, albeit with variable effect sizes. With a prospective longitudinal design, we sought to explain that variability by addressing questions about timing of the depression across pregnancy and the early postpartum, the role of high symptom levels relative to diagnosed depression, comorbidity with anxiety, and the potential mediating role of neuroendocrine functioning. Primiparous women (n = 77) with histories of depression prior to pregnancy were assessed for cortisol levels monthly beginning by mid-pregnancy. Depression symptom levels and diagnostic status were similarly assessed monthly in pregnancy and also until infants reached three months of age, when mothers completed the Infant Behavior Questionnaire-Revised to measure infant negative affectivity. Antenatal depression symptoms and infant negative affectivity were positively associated (r = .39). Controlling for depression symptom levels in other trimesters, only second trimester depression symptoms predicted higher infant negative affectivity (β = .44). With postpartum depression symptom levels in the model, only antenatal depression symptoms predicted infant negative affectivity (β = .45). In the context of depression, neither antenatal anxiety symptoms nor anxiety disorder diagnosis were associated with infant NA scores. The hypothesized role of elevated maternal cortisol as a mechanism for the association between antenatal depression and infant NA was not supported. Our findings contribute to efforts to more precisely identify infants of perinatally depressed mothers who are at greater risk for elevated negative affectivity, suggesting a window of vulnerability in mid pregnancy and the need for further study of potential mechanisms.     

Precursors of social emotional functioning among full-term and preterm infants at 12 months: Early infant withdrawal behavior and symptoms of maternal depression

This study forms part of a longitudinal investigation of early infant social withdrawal, maternal symptoms of depression and later child social emotional functioning. The sample consisted of a group of full-term infants (N = 238) and their mothers, and a group of moderately premature infants (N = 64) and their mothers. At 3 months, the infants were observed with the Alarm Distress Baby Scale (ADBB) and the mothers completed the Edinburgh Postnatal Depression Scale (EPDS). At 12 months, the mothers filled out questionnaires about the infants’ social emotional functioning (Infant Toddler Social Emotional Assessment and the Ages and Stages Questionnaire-Social Emotional). At 3 months, as we have previously shown, the premature infants had exhibited more withdrawal behavior and their mothers reported elevated maternal depressive symptoms as compared with the full-born group. At 12 months the mothers of the premature infants reported more child internalizing behavior. These data suggest that infant withdrawal behavior as well as maternal depressive mood may serve as sensitive indices of early risk status. Further, the results suggest that early maternal depressive symptoms are a salient predictor of later child social emotional functioning. However, neither early infant withdrawal behavior, nor gestational age, did significantly predict social emotional outcome at 12 months. It should be noted that the differences in strength of the relations between ADBB and EPDS, respectively, to the outcome at 12 months was modest. An implication of the study is that clinicians should be aware of the complex interplay between early infant withdrawal and signs of maternal postpartum depression in planning ports of entry for early intervention.     

Maternal experience of their infants’ crying in the context of war trauma: Determinants and consequences

We examined, first, how prenatal maternal mental health and war trauma predicted mothers’ experience of their infant crying, indicated by emotions, cognitions, and behavior; and second, how these experiences influenced the mother–infant interaction and infant development. Participants were 511 Palestinian mothers from the Gaza Strip, reporting their war trauma, symptoms of posttraumatic stress disorder (PTSD), depression, and perceived stress during pregnancy (Time 1). They reported experiences of infant crying at 4 months (Time 2), and the mother–infant interaction and infant sensorimotor and language development at 12 months of infants’ age (Time 3). Results revealed that maternal mental health problems, but not war trauma, were important to experiences of infant crying. A high level of PTSD symptoms predicted negative emotions evoked by infant crying, and high depressive symptoms predicted low active and positive responses to crying. Unexpectedly, high prenatal perceived stress predicted high active and positive responsiveness. Concerning the consequences, mothers’ sensitive interpretation of infant crying predicted optimal infant sensorimotor development, and mothers’ active and positive responses predicted high emotional availability in mother–infant interaction. Crying is the first communication tool for infants, and mothers’ sensitive responses to crying contribute to infant well-being. Therefore, reinforcing mother's optimal responses is important when helping war-affected dyads.     

Randomized controlled trial of a prenatal focused coparenting consultation for unmarried black fathers and mothers: One-year infant and family outcomes

In the infant mental health field, scant conceptual attention has been given to coparenting and family adaptations of non-white family systems, with no evidence-based, community-informed coparenting interventions responsive to unmarried Black mothers’ and fathers’ life circumstances. This study examined 1-year post-partum child and family outcomes of a novel, modest dosage (six sessions) prenatal focused coparenting consultation (FCC) using randomized controlled trial methodology. One-hundred-thirty-eight expectant families (one or both parents identified as Black/African American) were randomized to an intervention (N = 70) or treatment-as-usual (TAU; control) condition (N = 68). TAU families received navigational support in accessing existing community services for pregnant families. Intervention families received TAU plus 6 dyadic FCC sessions led by a Black male-female Community Mentor team. When infants were three and 12 months old, parents reported on coparenting, father engagement, interparental aggression, depressive symptoms, and infant social and emotional adjustment. Intent-to-treat analyses focusing on 12-month post-partum data indicated significant intervention effects on coparenting, interparental psychological aggression, and infants’ emotional adjustment. Improvement was also seen in depression and father engagement, with gains for both groups. Results suggest FCC delivered by same-race Community Mentors to unmarried Black coparents transitioning to parenthood supports infant and family adaptation during the first year of life.     

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.     

Individual differences in non-clinical maternal depression impact infant affect and behavior during the still-face paradigm across the first year

Maternal depression can significantly impact mothers’ sensitivity to their infants’ needs as well as infants’ social and emotional development. The still-face paradigm (SFP) is widely used to assess infants’ understanding of the contingency between their own behavior and that of their caregivers, as well as infants’ ability to self-regulate arousal levels during sudden changes in maternal responsiveness. Infants of clinically depressed mothers display blunted levels of negative affect compared to infants of non-depressed mothers during the still-face (SF) phase. However, little is known about whether individual differences in elevated, non-clinical levels of maternal depression similarly affect mother-infant interactions. The current study examines the longitudinal effects of non-clinical maternal depression on infant and maternal behaviors during the SFP. Infants (N = 63) were assessed at 5 and 9 months and maternal depression was assessed at 5 months using the Beck Depression Inventory (BDI). Infants of mothers with elevated levels of depression displayed less negative engagement during the SF phase compared to infants of mothers with lower levels of depression. This effect was present at 5 months, but not at 9 months. Findings demonstrate that non-clinical levels of maternal depressive symptomatology can have a significant impact on infants’ affective regulation during the first half of the first year of life, but this does not necessarily have a long-lasting influence later in infancy. Interventions may want to target mothers with non-clinical depression to promote healthy infant social and emotional development.     

Perceived partner support in pregnancy predicts lower maternal and infant distress

Maternal postpartum emotional distress is quite common and can pose significant risk to mothers and infants. The current study investigated mothers' relationships with their partners during pregnancy and tested the hypotheses that perception of prenatal partner support is a significant predictor of changes in maternal emotional distress from midpregnancy to postpartum, and contributes to maternal ratings of infant distress to novelty. Using a prospective longitudinal design, 272 adult pregnant women were interviewed regarding their partner support, relationship satisfaction, and interpersonal security (attachment style and willingness to seek out support), and they completed standardized measures of prenatal symptoms of depression and anxiety (distress). At 6 to 8 weeks' postpartum, mothers reported these symptoms again and completed measures of their infants' temperament. Structural equation modeling (SEM) was used to test direct and indirect contributions of partner support, relationship satisfaction, and interpersonal security to maternal and infant postpartum distress. Mothers who perceived stronger social support from their partners midpregnancy had lower emotional distress postpartum after controlling for their distress in early pregnancy, and their infants were reported to be less distressed in response to novelty. Partner support mediated the effects of mothers' interpersonal security and relationship satisfaction on maternal and infant outcomes. A high-quality, supportive partner relationship during pregnancy may contribute to improved maternal and infant well-being postpartum, indicating a potential role for partner relationships in mental health interventions, with possible benefits for infants as well.     

Maternal and infant affect at 4 months predicts performance and verbal IQ at 4 and 7 years in a diverse population

Using existing longitudinal data from 570 infants in the Maternal Lifestyle Study, we explored the predictive value of maternal and infant affect and maternal vocalizations during 2 minutes of face‐to‐face interactions at 4 months on IQ scores at 4.5 and 7 years. After controlling for demographic factors, maternal depression, and prenatal drug exposure, maternal positive affect and maternal positive vocalizations emerged as predictors of both verbal and performance IQ at 4.5 and 7 years. Although infant positive affect during the interaction with the mother was not predictive of these outcome measures, infant positive affect towards an examiner predicted verbal but not performance IQ at 4.5 years. These results suggest that maternal positive affect may index emotional engagement in interaction that facilitates both verbal and nonverbal cognitive development, while infant social positive affect is specifically related to the acquisition of verbal reasoning abilities. These findings are significant because they are based on a discrete snapshot of observable behavior in infancy (just 2 minutes of interaction), because they extend the range of maternal behaviors and characteristics known to support positive developmental outcomes, and because they are derived from high‐risk infants where prevention efforts may be beneficial. Potential mechanisms for these associations are discussed, as are the clinical implications for identifying dyads most in need of targeted interventions.     

War trauma and infant motor,cognitive, and socioemotional development: Maternal mental health and dyadic interaction as explanatory processes

BackgroundTaking care of infants in conditions of war is highly demanding and a few studies reveal the negative impact of war trauma on maternal and infant well-being. Yet, little is known regarding the influence of trauma on infant development and the potential explanatory mechanisms. First, the present study examines how mothers’ prenatal exposure to traumatic war events is associated with infant cognitive, motor, and socioemotional development. Second, it analyses the mediating roles of maternal postpartum mental health problems, quality of dyadic mother-infant interaction, and earlier infant development (at six months) in the association between prenatal traumatic war events and infants’ developmental skills at 18 months.MethodThis prospective three-wave study involved 502 Palestinian pregnant females in their first trimester during the 2014 Gaza War and participated at delivery (T1) and when the child was six (T2;N = 392) and eighteen (T3; N = 386) months of age. Mothers reported their exposure to traumatic war events (human and material losses, horrors, and threat to life) at T1 and T2, and researchers photo-documented the extent of destruction at T1. Mothers reported infants’ language, fine- and gross-motor, and socioemotional skills at T2 and researchers tested infants’ motor, cognitive-language and socioemotional skills using the Bayley Scales of Infant development (BSID-II) at T3. Mothers reported their mental health problems (symptoms of post-traumatic stress disorder [PTSD], depression and somatization) at T2 and T3 as well as dyadic interaction quality (the emotional availability self-report, [EA-SR] brief) at T2.ResultsFirst, the structural equation model (SEM) on direct effects indicated, in contrast to our hypotheses, that maternal prenatal exposure to traumatic war events did not associate with infants’ developmental skills at T2 and predicted higher level of developmental skills at T3. Second, as hypothesized, we found two negative underlying mechanisms (paths) between high exposure and low levels of motor, cognitive-language, and socioemotional skills at T3: (1) through increased maternal mental health problems at T2, which then were associated with problems at T3, and (2) through increased maternal mental health problems at T2, which then were associated with a low quality of mother-infant-interaction and low level of infant developmental skills at T2.ConclusionImproving maternal mental health and encouraging close and positive dyadic interaction can be critical for infant sensorimotor, cognitive, and socioemotional development in war conditions.     

The impact of prenatal serotonin reuptake inhibitor (SRI) antidepressant exposure and maternal mood on mother–infant interactions at 3 months of age

Exposure to maternal depression increases risks for altered mother–infant interactions. Serotonin reuptake inhibitor (SRI) antidepressants are increasingly prescribed to manage antenatal maternal illness. The impact of SRIs on early mother–infant interactions was unknown. Three-month-old infants of 32 depressed mothers treated with SRI medications during pregnancy and 43 non-medicated mothers were studied. Using an established face-to-face mother–infant interaction paradigm, dyad interactions were studied with and without a toy. Videotaped sessions yielded 4 measures: maternal sensitivity, dyadic organization, infant readiness to interact, and maternal interruptive behaviors. Even with prenatal SRI treatment, depressed mothers interrupted their infants more during toy play. In the absence of prenatal SRI treatment, maternal postnatal depression adversely influenced infant behavior. Higher levels of maternal depression symptoms at 3 months predicted poorer infant readiness to interact during the toy session. Conversely, in the SRI-exposed group, higher prenatal depression scores predicted greater infant readiness to interact at 3 months. Increased infant readiness with SRI exposure suggests a “fetal programming effect” whereby prenatal maternal mood disturbances shaped a future response to a postnatal depressed maternal environment.     

Maternal postnatal psychiatric symptoms and infant temperament affect early mother-infant bonding

Postnatal mother-infant bonding refers to the early emotional bond between mothers and infants. Although some factors, such as maternal mental health, especially postnatal depression, have been considered in relation to mother-infant bonding, few studies have investigated the role of infant temperament traits in early bonding. In this study, the effects of maternal postnatal depressive and anxiety symptoms and infant temperament traits on mother-infant bonding were examined using both mother and father reports of infant temperament. Data for this study came from the first phase of the FinnBrain Birth Cohort Study (n = 102, father reports n = 62). After controlling for maternal symptoms of depression and anxiety, mother-reported infant positive emotionality, measured by infant smiling was related to better mother-infant bonding. In contrast, infant negative emotionality, measured by infant distress to limitations was related to lower quality of bonding. In regards to father-report infant temperament, only infant distress to limitations (i.e., frustration/anger) was associated with lower quality of mother-infant bonding. These findings underline the importance of infant temperament as one factor contributing to early parent-infant relationships, and counseling parents in understanding and caring for infants with different temperament traits.     

Association of prenatal attachment and early childhood emotional,behavioral, and developmental characteristics: A longitudinal study

This study examines the associations between prenatal attachment and child development, socioemotional behavioral problems, and competence at early childhood. It also inquires whether maternal depression and anxiety at the prenatal period and at early childhood are associated with child outcomes. The study consisted of 83 mothers and their children. Data regarding the prenatal attachment, depression, and anxiety were collected during Weeks 28 to 40 of gestation. When the children were 21 to 31 months old, the Brief Infant and Toddler Social Emotional Assessment (BITSEA) and the Ankara Developmental Screening Inventory (ADSI) were applied to children along with Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) administered to mothers. Results showed that prenatal attachment scores significantly correlated with BITSEA-Competency subscale scores and ADSI total scores at early childhood, r(83) = 0.246, P = .025, and r(82) = 0.316, P = .004, respectively. Prenatal attachment levels were found to be the predictors of both behavioral and emotional competence and development at early childhood, b = 0.081, t(83) = 2.273, P = .014, and b = 0.281, t(83) = 3.225, P = .002, respectively. In addition, prenatal attachment was shown to be even a stronger predictor of development than was worsening maternal depression at early childhood, b = −0.319, t(83) = 2.140, P = .035. Our results indicate that fostering prenatal attachment may be beneficial for better infant outcomes at early childhood.     

MATERNAL TRAUMA AFFECTS PRENATAL MENTAL HEALTH AND INFANT STRESS REGULATION AMONG PALESTINIAN DYADS

We examined how diverse and cumulated traumatic experiences predicted maternal prenatal mental health and infant stress regulation in war conditions and whether maternal mental health mediated the association between trauma and infant stress regulation. Participants were 511 Palestinian mothers from the Gaza Strip who reported exposure to current war trauma (WT), past childhood emotional (CEA) and physical abuse, socioeconomic status (SES), prenatal mental health problems (posttraumatic stress disorder and depression symptoms), and perceived stress during their secondtrimester of pregnancy as well as infant stress regulation at 4 months. While all trauma types were associated with high levels of prenatal symptoms, CEA had the most wide‐ranging effects and was uniquely associated with depression symptoms. Concerning infant stress regulation, mothers’ CEA predicted negative affectivity, but only among mothers with low WT. Against hypothesis, the effects of maternal trauma on infant stress regulation were not mediated by mental health symptoms. Mothers’ higher SES was associated with better infant stress regulation whereas infant prematurity and male sex predisposed for difficulties. Our findings suggest that maternal childhood abuse, especially CEA, should be a central treatment target among war‐exposed families. Cumulated psychosocial stressors might increase the risk for transgenerational problems.     

Maternal prenatal psychological distress and temperament in 1–4 month old infants – A study in a non-western population

In this longitudinal study, conducted in women attending antenatal visits at the obstetrics and gynecology clinic of a general hospital in Bangalore, India, we aimed to assess the relationship between prenatal distress in mothers, and maternal report of infant temperament at four months. 100 mothers with normal full term deliveries completed the General Health Questionnaire-28 item version (GHQ) in the third trimester and postnatally. Salivary cortisol and temperament (using the Early Infancy Temperament Questionnaire – EITQ) were assessed in their infants aged 1–4 months. In this study, maternal prenatal psychological distress was not significantly associated with maternal report of difficult temperament in infants. Infants of mothers who were a negative screen for psychological distress (GHQ < 7), n = 85 had higher scores on the adaptability and approach dimensions of temperament. Infant salivary cortisol was significantly higher in infants with higher intensity scores. These results introduce the possibility of cultural differences in the relationship between prenatal distress in the mother and infant temperament. These could be factors linked to child rearing practices or to the measures employed to study infant temperament. These findings derive from a small sample with few mothers with psychological distress, and need replication in a larger sample.     

Do early parental postnatal depression,attachment style and perceived social support affect neurodevelopmental outcomes of premature infants?

BackgroundThe birth of a premature infant is both a stressful event for both parents and associated with an increased rate of postnatal depression (PND). Additionally some mothers may have delayed feelings of attachment to their babies because of the medical procedures or possible medical complications. Social support is known as an important factor for well-being in the postnatal period. However there is scarce data about these factors for fathers. We aimed to identify the impact of parental PND, attachment style and social support on premature infant development considering the prematurity degree and risk groups.MethodsThis prospective study was conducted by including 96 infants who were born preterm. Mothers and fathers were given Edinburgh Postnatal Depression Scale (EPDS), Adult Attachment Style Scale (AASS), and Multidimensional Scale of Perceived Social Support (MSPSS) to fill out when their infants’ corrected age was 3 months. The developmental evaluation was conducted with Bayley III at the corrected 6 months and 18 months of age.ResultsPostnatal depression scores were more in mothers than fathers, the rates of secure attachment and social support were similar between mothers and fathers. Factors associated with the neurodevelopmental outcomes including prematurity degree and risk groups, EPDS, AASS and MSPSS scores were analyzed for both parents. In multivariate analysis, fathers’ depression scores were inversely associated with cognitive development (p = 0.030, R² = 0.080, B=-0.283) and mothers’ anxious/ambivalent attachment style was inversely associated with language development (p = 0.011, R² = 0.108, B=-0.329) at the age of corrected 6 months old.ConclusionsOur findings underscore that the efforts to improve developmental outcomes of premature infants should include parental well-being taking into account new fathers’ depressive symptomatology and maternal anxious/ambivalent attachment.     

Maternal depression: A review of relevant treatment approaches for mothers and infants

The negative impact of postpartum depression on the mother‐infant relationship and infant development more generally has been well documented. Compared to infants of nondepressed mothers, infants of depressed mothers have been shown to be less securely attached to their caregivers and often have cognitive, emotional, and behavioral deficits that persist well into childhood. Recent evidence has suggested that reduction of maternal depressive symptoms may itself not be sufficient to prevent negative effects on children. Rather, treatments that target the mother‐infant relationship may have great potential in providing a buffer against the potentially damaging effects of postpartum depression. Based on our review of several treatment‐outcome studies, we conclude that mother‐infant psychotherapies and home‐based interventions are generally efficacious in their goal of ameliorating detrimental consequences for children of depressed mothers. Nonetheless, the field must continue to investigate the extent to which treatment gains are maintained over time and the mechanisms by which protective effects occur. It is likely that the most efficacious treatment approaches will be those that address the needs of the mother, the infant, and their relationship.     

Maternal sensitivity moderates the impact of prenatal anxiety disorder on infant responses to the still-face procedure

Animal studies have demonstrated the interactive effects of prenatal stress exposure and postnatal rearing style on offspring capacity to manage stress. However, little is known about how parenting quality impacts the association between maternal prenatal anxiety and stress reactivity in human infants. This prospective study examined the impact of prenatal anxiety disorder and maternal caregiving sensitivity on infants’ responses to a standardised interactive stressor (still-face procedure). Eighty-four women completed a clinical interview during pregnancy to assess anxiety symptoms meeting DSM-IV diagnostic criteria. At infant age 7 months, maternal sensitivity to infant distress and infant negative affect were observed and coded during the still-face procedure. Maternal postnatal (concurrent) anxiety and depression were also assessed at this time. Results indicated a negative association between maternal sensitivity to infant distress and infant negative affect responses to the still-face procedure. An unexpected finding was a positive association between parity and infant reactivity. The main effect for sensitivity was qualified by a significant interaction, p < .05, suggesting that the impact of sensitivity was particularly marked among infants of women who experienced an anxiety disorder during pregnancy. This finding is consistent with a cumulative risk model suggesting that maternal prenatal anxiety and quality of maternal care act in concert to shape infant outcomes.     

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.
