The parental bonds of adolescent girls and next-generation maternal-infant bonding: findings from the Victorian Intergenerational Health Cohort Study

Maternal stressors and maternal bonding among immigrant and Refugee Arab Americans resettled in the United States

Maternal bonding with the infant and child is essential for the growth and development of the child, and for establishing the relationship between them. The effect of maternal acculturative stress, trauma, and depressive symptoms on maternal bonding has been established in nonimmigrant populations, but not in immigrant and refugee populations. In this study, we aimed to (1) examine the relationships among maternal psychosocial stress (acculturative stress, posttraumatic stress), depressive symptoms, and maternal bonding, and (2) examine whether maternal depression is a mediator of the relationship between maternal psychosocial stress and maternal bonding among a sample of Arab American immigrant and refugee mothers. Using a cross-sectional design, we recruited 78 immigrant and refugee Arab American mothers. Acculturative stress was correlated with posttraumatic stress (ρ = 0.56, p < 0.001), depressive symptoms (ρ = 0.48, p < 0.001), and bonding impairment (ρ = 0.39, p < 0.001). Posttraumatic stress and depressive symptoms were also correlated with maternal bonding impairment (ρ = 0.39, and 0.52, respectively, p < 0.001 for both). The effect of maternal psychosocial stress on maternal bonding was mediated by depressive symptoms. We concluded that higher levels of acculturative stress and posttraumatic stress were associated with higher levels of depressive symptoms and impairment of maternal bonding. Additionally, maternal depressive symptoms mediated the relationship between maternal stress and bonding. Assessing the stressors and depressive symptoms of immigrant and refugee mothers is key to avoiding negative effects on child outcomes.

The concept analysis of parent-infant bonding during pregnancy and infancy: a systematic review and meta-synthesis

INTRODUCTION

Despite the emerging body of literature on mother-to-infant bonding and the associated variables, there are various definitions of bonding construct. Also, there is a lack of a comprehensive conceptual framework of antecedents and consequences of bonding that would guide empirical work.

OBJECTIVE

Aim of the study was to provide a systematic review and synthesis of concept analysis studies on maternal-foetal, mother-infant, or father-infant bonding.

METHOD

A systematic search was performed in PubMed, EBSCOHost (including PsycINFO), ProQuest, and CINAHL. In addition, a hand search was conducted. Papers were eligible for inclusion if they conducted concept analyses on mother or father to foetus/infant bonding. A qualitative meta-synthesis was applied to synthesise the findings.

RESULTS

Eight papers on concept analyses were eligible for inclusion. In meta-synthesis, six aspects of parent-to-(unborn) child bonding emerged, including direction, domain, process, timing, endurance, and parental gender. Defining attributes are (i) a close relationship, (ii) filled with positive parental affection, (iii) manifested during pregnancy as monitoring foetal development and behaviour and after childbirth in proximity and interaction. Antecedents, affecting factors, and consequences of the parent-child bonding have been summarised.

CONCLUSION

Parent-infant bonding refers to an emotional, behavioural, cognitive, and neurobiological tie of the parent to the (unborn) child, as a process from intention to have a child throughout infancy. This is a parental-driven process which can continue to evolve throughout child's and parent's life, characterised as enduring, committed, and engaged. Based on meta-synthesis, a conceptual structure of parent-infant bonding has been provided, which needs further empirical testing.

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.

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.

The prediction of perceived parenting style on mother-infant bonding

BACKGROUND

There are limited studies on the associations among parenting style, postpartum depression, and mother-infant bonding.

OBJECTIVE

The aims of this study are investigating how the parenting style of maternal grandparents predicted the mothers' bonding with their infants. The mediating roles of postpartum depression were also explored.

PARTICIPANTS AND SETTING

A community sample of 227 postpartum women participated in this study. The participants primarily consisted of women who gave birth within six months (89.9%).

METHODS

A cross-sectional and convenient sampling strategy was applied. Instruments were Parental Bonding Instrument, Edinburgh Postnatal Depression Scale, Postpartum Bonding Questionnaire, and Background Form.

RESULTS

In the young infant group (i.e. mothers with infants not older than three months), the results indicated that maternal protection could predict "impaired bonding" (β = 0.20, p < .05). This prediction was mediated by postpartum depression (β = 0.32, p < .001). In the older infant group, paternal and maternal care could directly predict "rejection and anger" (β = -0.20, -0.22 respectively, p < .05). Maternal protection could predict three bonding factors (β = 0.25-0.29, p < .05, 0.01). Postpartum depression acted as total mediator for "impaired bonding"(β = 0.45, p <. 001), and acted as partial mediators in "rejection and anger" and "anxiety about care" (β = 0.45, 0.28, ps < .001, .01).

CONCLUSIONS

Perceived parenting style (especially maternal protection) has impacts on adverse mother-infant bonding. Furthermore, the impact is more prominent on mothers of older infants. "Rejection and anger" could be the most vulnerable bonding factor affected by parenting style. Since postpartum depression mediates the predictions, interventions could concurrently address maternal parenting style and postpartum depression.

From adolescence to parenthood: a multi-decade study of preconception mental health problems and postpartum parent-infant bonds

PURPOSE

To examine associations between anxiety and depressive symptoms across adolescence and young adulthood with subsequent maternal- and paternal-infant bonding at 1 year postpartum.

METHODS

The data were from a prospective, intergenerational cohort study. Participants (381 mothers of 648 infants; 277 fathers of 421 infants) self-reported depression and anxiety at three adolescent waves (ages 13, 15 and 17 years) and three young adult waves (ages 19, 23 and 27 years). Subsequent parent-infant bonds with infants were reported at 1 year postpartum (parent age 29-35 years). Generalised estimating equations (GEE) separately assessed associations for mothers and fathers.

RESULTS

Mean postpartum bonding scores were approximately half a standard deviation lower in parents with a history of persistent adolescent and young adult depressive symptoms (maternal β_adj = - 0.45, 95% CI - 0.69, - 0.21; paternal β_adj = - 0.55, 95% CI - 0.90, 0.20) or anxiety (maternal β_adj = - 0.42, 95% CI - 0.66, - 0.18; paternal β_adj = - 0.49, 95% CI - 0.95, 0.03). Associations were still mostly evident, but attenuated after further adjustment for postpartum mental health concurrent with measurement of bonding.

CONCLUSIONS

Persistent symptoms of depression or anxiety spanning adolescence and young adulthood predict poorer emotional bonding with infants 1-year postbirth for both mothers and fathers.

Parent and Peer Attachments in Adolescence and Paternal Postpartum Mental Health: Findings From the ATP Generation 3 Study

Background: When adolescent boys experience close, secure relationships with their parents and peers, the implications are potentially far reaching, including lower levels of mental health problems in adolescence and young adulthood. Here we use rare prospective intergenerational data to extend our understanding of the impact of adolescent attachments on subsequent postpartum mental health problems in early fatherhood.

Methods: At age 17–18 years, we used an abbreviated Inventory of Parent and Peer Attachment to assess trust, communication, and alienation reported by 270 male participants in their relationships with mothers, fathers, and peers. More than a decade later, we assessed the adult males, now fathers, at 12 months postpartum (N = 409 infant offspring) for symptoms of depression, anxiety, and stress. Logistic regression was used to examine the extent to which attachment dimensions predicted paternal postpartum mental health, adjusting for potential confounding, and with assessment for interactions between parent and peer attachments.

Results: Trust in mothers and peers, and good communication with fathers during adolescence, were associated with 5 to 7 percentage point reductions in postpartum mental health symptoms in early fatherhood. Weak evidence of parent-peer interactions suggested secure attachments with either parent or peer may compensate for an insecure attachment with the other.

Conclusions: Our results suggest that fostering trust and communication in relationships that adolescent boys have with parents and peers may have substantial effects on rates of paternal postpartum mental health problems. The protective benefits may be preventative in intergenerational cycles of risk for mental health problems.

The Victorian Intergenerational Health Cohort Study (VIHCS): Study design of a preconception cohort from parent adolescence to offspring childhood

BACKGROUND

There is increasing evidence that parental determinants of offspring early life development begin well before pregnancy.

OBJECTIVES

We established the Victorian Intergenerational Health Cohort Study (VIHCS) to examine the contributions of parental mental health, substance use, and socio-economic characteristics before pregnancy to child emotional, physical, social, and cognitive development.

POPULATION

Men and women were recruited from the Victorian Adolescent Health Cohort (VAHCS), an existing cohort study beginning in 1992 that assessed a representative sample of 1943 secondary school students in Victoria, Australia, repeatedly from adolescence (wave 1, mean age 14 years) to adulthood (wave 10, mean age 35 years).

METHODS

Victorian Adolescent Health Cohort participants with children born between 2006 and 2013 were recruited to VIHCS and invited to participate during trimester three, at 2 months postpartum, and 1 year postpartum. Parental mental health, substance use and socio-economic characteristics were assessed repeatedly throughout; infant characteristics were assessed postnatally and in infancy. Data will be supplemented by linkage to routine datasets. A further follow-up is underway as children reach 8 years of age.

PRELIMINARY RESULTS

Of the 1307 infants born to VAHCS participants between 2006 and 2013, 1030 were recruited to VIHCS. At VIHCS study entry, 18% of recruited parents had preconception common mental disorder in adolescence and young adulthood, 18% smoked daily in adolescence and young adulthood, and 6% had not completed high school. Half of VIHCS infants were female (48%), 4% were from multiple births, and 7% were preterm (<37 weeks' gestation).

CONCLUSIONS

Victorian Intergenerational Health Cohort Study is a prospective cohort of 1030 children with up to nine waves of preconception parental data and three waves of perinatal parental and infant data. These will allow examination of continuities of parental health and health risks from the decades before pregnancy to offspring childhood, and the contributions of exposures before pregnancy to offspring outcomes in childhood.
