Mother-to-infant bonding mediates the effects of depressive and anxious postpartum symptoms on parenting stress

A number of studies have suggested close associations between maternal postpartum mental health (depressive and anxious symptoms), mother-infant bonding, and parenting stress. However, the relationship between maternal bonding and parenting stresshas hardly been explored in published literature. This cross-sectional study explored whether maternal bonding could mediate the effect of postpartum maternal mental health on parenting stress. This study assessed maternal bonding (MPAS), depressive and anxious symptoms (EPDS; STAI), and parenting stress (PSI) at 3 months postpartum in a community sample of 105 women (M (SD) = 32.60 (4.18) years old). Spearman's correlation analyses showed moderate to high correlations between these factors. The three mediation models run showed that mother's MPAS partially mitigates the effects of EPDS (b = 0.71; SE = 0.217; 95% CI = 0.290/1.136) and STAI State (b = 0.39; SE = 0.113; 95% CI = 0.178/0.625) on PSI, and totally mediated the relationship between STAI Trait and PSI (b = 0.59; SE = 0.155; 95% CI = 0.303/0.912). Maternal bonding resulted to be a relevant factor in the association between maternal mental health and parenting stress. This highlights the importance of interventions focusing on mother-infant relationship to reduce parenting stress and prevent developmental difficulties in children.

Infantile atopic dermatitis and maternal-infant bonding: a mixed methods study

BACKGROUND

Childhood atopic dermatitis can have a negative effect on caregivers' quality of life and stress levels due to the burdensome nature of its treatment. Given that the condition often emerges in infancy, atopic dermatitis-related stress also carries the potential to negatively affect the developing mother-infant bond. While it is plausible that atopic dermatitis has a negative impact on maternal-infant bonding, these relationships have not been studied directly. In light of this gap, the current study investigated the association between infantile atopic dermatitis and the maternal-infant bond using a mixed-method design.

METHODS

Mothers of infants (< 19 months) with atopic dermatitis were recruited from social media and medical clinics between October 2021 and May 2022. Mothers with infants unaffected by inflammatory skin conditions were also recruited to serve as a control group. Participants were asked to complete questionnaires related to their demographics, child's health, and mother-infant bond. Multiple linear regression analyses were used to assess bonding quality among cases and controls. A subset of cases were also asked to participate in semi-structured interviews focused on infantile atopic dermatitis and the maternal-infant bond.

RESULTS

The final sample consisted of 32 cases and 65 controls. Scores on the impaired bonding and risk of abuse subscales did not significantly differ between cases and controls. However, mothers of infants with atopic dermatitis did report lower levels of caregiving anxiety (b = - 1.47, p < 0.01) and pathological anger/rejection (b = - 1.74, p = 0.02) relative to controls. Qualitative findings suggest that the topical therapies required to manage atopic dermatitis may strengthen the bond between some mothers and infants.

CONCLUSION

Findings suggest that atopic dermatitis does not have a negative impact on maternal-infant bonding and may actually improve bonds in some cases. In light of this finding, clinicians may leverage the potentially positive impact of atopic dermatitis-related caregiving on the maternal-infant bond to encourage caregivers to remain adherent to their child's topical treatments.

The mediation role of resilience and postpartum traumatic stress disorder on parental attachment and the maternal-infant bonding

AIMS

This study aimed to evaluate the correlation between parental attachment, resilience, postpartum traumatic stress disorder (PTSD), and maternal-infant bonding at 1 to 3 months postpartum. The mediation effect of resilience and PTSD on the postpartum parental attachment and maternal-infant bond was also evaluated.

DESIGN

A cross-sectional research design was used.

METHODS

A total of 400 postpartum women examined at a tertiary hospital in Wuhan from January 2021 to June 2021 were enrolled in the study. At about 1 to 3 months after giving birth, the women were asked to complete the Postpartum Bonding Questionnaire (PBQ), Connor-Davidson Resilience scale(CD-RISC), PTSD CheckList-Civilian version (PCL-C), and the Parental Bonding Instrument (PBI). The data were summarized using descriptive statistics. Mediation analyse and the Spearman correlation (r) were used to correlate the resilience and PTSD questionnaire scores.

RESULTS

The care attachment dimension was significantly associated with resilience (r = 0.24, p < 0.01), PTSD (r = - 0.27, p < 0.01), and maternal-infant bonding (r = 0.10, p < 0.01), and the overprotection attachment dimension was significantly associated with resilience (r = - 0.11, p < 0.01), PTSD (r = 0.33, p < 0.01), and maternal-infant bonding (r = 0.16, p < 0.01). Resilience and PTSD can mediate the relationship between attachment and maternal-infant bonding.

CONCLUSION

Parental attachment, resilience, and PTSD significantly affect maternal-infant bonding at 1 to 3 months postpartum.

IMPACT

This study demonstrated that new interventions aimed at addressing PTSD symptoms and improving resilience might increase parental attachment and maternal-infant bonding after birth. However, further research is required to evaluate the success of these interventions.

Maternal-infant bonding and partner support during pregnancy and postpartum: Associations with early child social-emotional development

The first 1000 days after conception are considered critical for healthy development and well-being throughout life. Fundamental to health practices during pregnancy and positive parenting after birth is the development of maternal-infant bonding. Previous research has demonstrated the importance of having an involved partner during pregnancy and in parenting for optimal maternal-infant bonding. The current study examined maternal-infant bonding and partner support during pregnancy and the postpartum period, and their associations with early child social-emotional development. A total of 227 women completed the Pre- and Postnatal Bonding Scale (PPBS) and Tilburg Pregnancy Distress Scale (TPDS) during pregnancy (32 weeks of gestation) and at 8 months postpartum, assessing maternal-infant bonding and partner support. Additionally, a questionnaire on social-emotional behavior of the Bayley Scales of Infant and Toddler Development was administered to mothers to measure child development at 2 years of age. Path analyses revealed an indirect positive effect of prenatal maternal-infant bonding on child social-emotional development through postnatal maternal-infant bonding, as well as mediating effects of pre- and postnatal maternal-infant bonding on the association between pre- and postnatal partner support and child social-emotional development. Our findings support the notion that an emotional connection from mother to child originates in pregnancy and that experiencing positive feelings towards the fetus promotes positive maternal-infant bonding after birth and social-emotional capacities of the child. Additionally, having a supportive partner during pregnancy and postpartum, might be essential for the development of optimal maternal-infant bonding.

The impact of postpartum social support on postpartum mental health outcomes during the COVID-19 pandemic

Social support is an influential component of postpartum recovery, adjustment, and bonding, which was disrupted by social distancing recommendations related to the COVID-19 pandemic. This study reports on changes in the availability of social support for postpartum women during the pandemic, investigates how those changes may have contributed to postpartum mental health, and probes how specific types of social support buffered against poor postpartum mental health and maternal-infant bonding impairment. Participants were 833 pregnant patients receiving prenatal care in an urban USA setting and using an electronic patient portal to access self-report surveys at two time points, during pregnancy (April-July 2020) and at ~12 weeks postpartum (August 2020-March 2021). Measures included an assessment of COVID-19 pandemic-related change in social support, sources of social support, ratings of emotional and practical support, and postpartum outcomes including depression, anxiety, and maternal-infant bonding. Overall self-reported social support decreased during the pandemic. Decreased social support was associated with an increased risk of postpartum depression, postpartum anxiety, and impaired parent-infant bonding. Among women reporting low practical support, emotional support appeared to protect against clinically significant depressive symptoms and impaired bonding with the infant. Decreases in social support are associated with a risk for poor postpartum mental health outcomes and impaired maternal-infant bonding. Evaluation and promotion of social support are recommended for healthy adjustment and functioning of postpartum women and families.

Associations between maternal psychological distress and mother-infant bonding: a systematic review and meta-analysis

PURPOSE

Maternal psychological distress and mother-infant bonding problems each predict poorer offspring outcomes. They are also related to each other, yet the extensive literature reporting their association has not been meta-analysed.

METHODS

We searched MEDLINE, PsycINFO, CINAHL, Embase, ProQuest DTG, and OATD for English-language peer-reviewed and grey literature reporting an association between mother-infant bonding, and multiple indicators of maternal psychological distress.

RESULTS

We included 133 studies representing 118 samples; 99 samples (110,968 mothers) were eligible for meta-analysis. Results showed concurrent associations across a range of timepoints during the first year postpartum, between bonding problems and depression (r = .27 [95% CI 0.20, 0.35] to r = .47 [95% CI 0.41, 0.53]), anxiety (r = .27 [95% CI 0.24, 0.31] to r = .39 [95% CI 0.15, 0.59]), and stress (r = .46 [95% CI 0.40, 0.52]). Associations between antenatal distress and subsequent postpartum bonding problems were mostly weaker and with wider confidence intervals: depression (r = .20 [95% CI 0.14, 0.50] to r = .25 [95% CI 0.64, 0.85]), anxiety (r = .16 [95% CI 0.10, 0.22]), and stress (r = .15 [95% CI - 0.67, 0.80]). Pre-conception depression and anxiety were associated with postpartum bonding problems (r = - 0.17 [95% CI - 0.22, - 0.11]).

CONCLUSION

Maternal psychological distress is associated with postpartum mother-infant bonding problems. Co-occurrence of psychological distress and bonding problems is common, but should not be assumed. There may be benefit in augmenting existing perinatal screening programs with well-validated mother-infant bonding measures.

Ecological momentary assessment of postpartum outcomes in mothers of multiples: lower maternal-infant bonding, higher stress, and more disrupted sleep

Research on mental health in mothers of multiples has neglected important outcomes like postpartum bonding and relationship satisfaction and is limited by reliance on single-administration, retrospective measures. This study fills these gaps by assessing previously unexamined variables and using ecological momentary assessment (EMA), wherein participants answer repeated, brief surveys to measure real-world, real-time outcomes. This online study recruited 221 women and compared outcomes in those who birthed multiples (n = 127, 57.47%) vs. singletons (n = 94, 42.53%). When recruited, participants were either 6-12 (n = 129, 58.37%) or 18-24 (n = 83, 37.56%) weeks postpartum. All 221 participants completed baseline measures of self-reported depression, anxiety, stress, sleep, relationship satisfaction, and maternal-infant bonding. One hundred thirty participants (58.82%) engaged in 7 days of EMA assessing self-reported momentary mood, stress, fatigue, bonding, and sleep. Data were analyzed using two-by-two ANOVAs and hierarchical linear modeling. Mothers of multiples reported more baseline parenting stress and less maternal-infant bonding than mothers of singletons (ps < .05). Mothers of multiples who were 6-12 weeks postpartum reported the lowest bonding (p = .03). Mothers of multiples also reported more momentary stress, overwhelm, nighttime awakenings, and wake time after sleep onset (ps < .05). The latter two variables positively correlated with momentary fatigue, stress, and worse mood (ps < .05). Mothers of multiples experienced worse postpartum bonding, more stress, and more interrupted sleep than mothers of singletons. This population may benefit from tailored postpartum interventions to decrease stress, increase bonding, and improve sleep.

Association between maternal-infant bonding and depressive symptoms in Neonatal Intensive Care Unit mothers: A case-control study

OBJECTIVES

Maternal perinatal depression has been associated with impaired mother-infant bonding. The adverse effect of this impaired bonding has been reported. This study aimed to investigate and compare the posnatal depressive symptoms and the mother-infant bonding in a Neonatal Intensive Care Unit (NICU) and of mothers with healthy newborns respectively. Secondly, was to explore the association between depressive symptomatology and bonding in both groups.

METHODS

In this case study, mothers in the early pospartum period who gave birth in the same perinatal center of Greece were recruited to participate. The cases consisted of 88 mothers of neonates who were hospitalized in the NICU and controls were 100 mothers of full-term healthy neonates. For the collection of the data questionnaires including demographics and perinatal variables were used. For the bonding and posnatal assessment, the Mother to Infant Bonding Scale, the Postpartum Bonding Questionnaire, and the Hospital Anxiety and Depression Scale were used.

RESULTS

There was a significant difference between the mean of bonding scores of NICU mothers and the control group (t = -2.696, P = 0.008). NICU mothers presented lower scores in bonding with the newborn compared to the control group and presented higher depression scores compared to those of controls (χ² = 28.588, P = 0.000). The depression scores were correlated with bonding scores in both groups.

DISCUSSION

A NICU admission has an impact on bonding and in some way interacts with maternal pospartum mental health, therefore more research is needed.

CONCLUSIONS

NICU mothers have been presented as more vulnerable than mothers of healthy infants since they expressed a lower mother-infant bonding and higher depression scores. The support of these vulnerable mothers and the facilitation of mother-infant bonding by the NICU staff is of utmost importance.

A prospective cohort study of post-traumatic stress disorder and maternal-infant bonding after first childbirth

OBJECTIVE

To investigate risk factors for childbirth-related post-traumatic stress disorder (CR-PTSD) measured 1-month after first childbirth, and the association between CR-PTSD and maternal-infant bonding.

METHODS

In this prospective cohort study 3006 nulliparous women living in Pennsylvania, USA, were asked about CR-PTSD at 1-month postpartum, and maternal-infant bonding at 1, 6 and 12-months postpartum. Multivariable logistic regression models identified risk factors for CR-PTSD and associations between CR-PTSD and maternal-infant bonding at 1, 6 and 12-months postpartum, controlling for confounding variables - including postpartum depression, stress and social support.

RESULTS

Nearly half (47.5%) of the women reported that during labor and delivery they were afraid that they or their baby might be hurt or die, and 225 women (7.5%) reported experiencing one or more CR-PTSD symptoms at 1-month postpartum. Depression, stress and low social support during pregnancy were associated with CR-PTSD, as well as labor induction, delivery complications, poor pain control, and unplanned cesarean delivery. Women with CR-PTSD reported a less positive childbirth experience, less shared decision-making, and were more likely to score in the bottom third on maternal-infant bonding at 1-month postpartum (adjusted odds ratio [aOR] 2.5, 95% CI 1.8-3.3, p < 0.001); at 6-months postpartum (aOR 2.1, 95% CI 1.5-2.8, p < 0.001); and at 12-months postpartum (aOR 2.2, 95% CI 1.6-3.0, p < 0.001).

CONCLUSION

In this large-scale prospective cohort study we found that CR-PTSD was consistently associated with lower levels of maternal-infant bonding over the course of the first year after first childbirth.

Maternal-infant bonding and perceptions of infant temperament: The mediating role of maternal mental health

BACKGROUND

There are associations between maternal mental health (anxiety and depression), maternal-infant bonding, and infant temperament. However, few studies have examined these variables simultaneously, and none have applied a parallel mediation analysis to consider maternal mental health as an explanatory variable. We aimed to examine these relationships, and whether mental health (anxiety and/or depression) mediates the observed association between maternal-infant bonding and infant temperament.

METHODS

Mothers with babies between zero and twelve months (N=527) were recruited to a cross-sectional online survey containing a battery of psychometric measures.

RESULTS

Correlation analyses examined relationships between the predictor (maternal-infant bonding), outcome (infant temperament), and mediator (maternal mental health; anxiety and/or depression). All associations were highly significant (p<.001). A parallel mediation (anxiety and/or depression) model was conducted, showing a significant indirect effect of maternal-infant bonding on infant temperament through anxiety, B = .04 (SE= .01) 95% CI= .01 to .07, but not through depression.

LIMITATIONS

Homogeneous sampling was an issue with mainly UK, married mothers, with higher socio-economic status and educational attainment participating. Therefore, further replication in diverse samples is required.

CONCLUSION

Associations were identified between maternal-infant bonding, infant temperament, and maternal mental health (anxiety and depression). However, only anxiety mediated the relationship between bonding and temperament. Healthcare professionals should consider the role of maternal anxiety when working with mothers who present with relational issues or report their infant as excessively challenging. These results signify the need to address maternal anxious and depressive symptoms as distinct issues considering their differential effects on parenting behaviour.

Maternal bonding, negative affect, and infant social-emotional development: A prospective cohort study

BACKGROUND

Theoretical perspectives and empirical evidence suggest that maternal bonding and negative affect play a role in supporting infant social-emotional development (Branjerdporn et al., 2017; Kingston et al., 2012; O'Donnell et al., 2014; Van den Bergh et al., 2017). However, the complex pathways likely to exist between these constructs remain unclear, with limited research examining the temporal and potentially bi-directional associations between maternal bonding and negative affect across pregnancy and infancy.

METHODS

The interrelationships between maternal bonding, negative affect, and infant social-emotional development were examined using multi-wave perinatal data from an Australian cohort study (N = 1,579). Self-reported bonding and negative affect were assessed at each trimester, and 8 weeks and 12 months postpartum. The Bayley-III social-emotional scale was administered at age 12 months.

RESULTS

Results revealed strong continuities in bonding and negative affect across pregnancy and postpartum. Small associations (β = -.10 to -.20) existed between maternal negative affect during pregnancy and poor early bonding. Higher postnatal maternal bonding predicted infant social-emotional development (β = .17).

LIMITATIONS

Limitations include a somewhat advantaged and predominantly Anglo-Saxon sample of families, and the use of self-report measures (though with strong psychometric properties). These limitations should be considered when interpreting the study findings.

CONCLUSIONS

Maternal bonding and negative affect are interrelated yet unique constructs, with suggested developmental interplay between mother-to-infant bonding and infant social-affective development.

Adult attachment style and maternal-infant bonding: the indirect path of parenting stress

BACKGROUND

The quality of maternal-infant bonding is related to important child outcomes. The literature has assumed that the ability to form relationships is a relatively stable trait, and research studies have suggested that a mother's attachment style in close adult relationships is related to mother-infant bonding. The transition to parenthood is also often stressful, and the adult attachment style may relate to parenting stress in the first year after birth. Such stress could possibly have a negative relationship with the mother-infant bond. In the present study, we examined the associations between maternal adult attachment styles and the quality of mother-infant bonding and whether this relationship is mediated by parenting stress.

METHODS

The present study sample comprised 168 women (mean age 31.0 years, SD 4.23 years). Between weeks 31 and 41 of gestation, the anxious and avoidant adult attachment dimensions were measured with the Experiences in Close Relationships questionnaire (ECR). Between 5 and 15 weeks after birth mother-infant bonding and parenting stress were measured with the Maternal Postnatal Attachment Scale (MPAS) and the Parenting Stress Index-Parent Domain (PSI-PD), respectively.

RESULTS

Both attachment-related avoidance and attachment-related anxiety correlated significantly and negatively with mother-infant bonding. However, a regression analysis showed that only attachment-related avoidance was a significant predictor of mother-infant bonding when controlling for demographic variables and maternal mental health history. The relationship between the adult attachment style and bonding was mediated by parenting stress. Higher scores on attachment avoidance and anxiety were related to increased stress, which was related to decreased quality of bonding. The overall parent domain and the subscale of competence in the parent-related stress dimension mediated between attachment avoidance and bonding, and the overall parent domain and the subscales of competence and role restriction mediated between attachment anxiety and bonding. There was no direct relationship between the adult attachment style and mother-infant bonding when parenting stress was included as a mediator.

CONCLUSIONS

This study illustrates that maternal adult attachment style relates to mother-infant bonding. This relationship was mediated by parenting stress. The results may have implications for the early identification of mothers at risk of having bonding difficulties.

Maternal brain in the process of maternal-infant bonding: Review of the literature

The mother-infant relationship is one of the most important bonds among all mammals and develops when a mother shows emotional and physical attention toward her infant. Studies suggest that maternal brain alterations, including structural and functional changes, may help mothers to form a strong bond with their infant. Investigation of mothers' unique response to her own infant, when smiling, crying or playing, could be the first step to uncover the neural bases of maternal-infant bonding. Studies are beginning to explore maternal brain changes underlying the process of mother-infant bonding. In this short review, we present an overview of the growing literature about maternal brain changes and neural responses to infant stimuli, which may underlie the process of forming the maternal-infant bond in healthy, non-clinical samples. Taken together, the maternal brain network consists mostly of areas related to salience/reward and emot processing, including the precuneus cortex, medial frontal cortex, anterior cingulate cortex, orbitofrontal cortex, caudate and nucleus accumbens, amygdala, and insula. Recommendations for future research are also discussed.
