Attachment, mating, and parenting

A modern evolutionary perspective emphasizing life history theory and behavioral ecology is brought to bear on the three core patterns of attachment that are identified in studies of infants and young children in the Strange Situation and adults using the Adult Attachment Interview. Mating and parenting correlates of secure/autonomous, avoidant/dismissing, and resistant/preoccupied attachment patterns are reviewed, and the argument is advanced that security evolved to promote mutually beneficial interpersonal relations and high investment parenting; that avoidant/dismissing attachment evolved to promote opportunistic interpersonal relations and low-investment parenting; and that resistant/preoccupied attachment evolved to foster “helper-at-the-nest” behavior and indirect reproduction.     

Postpartum depression: Etiology,treatment and consequences for maternal care

This article is part of a Special Issue “Parental Care”. Pregnancy and postpartum are associated with dramatic alterations in steroid and peptide hormones which alter the mothers' hypothalamic pituitary adrenal (HPA) and hypothalamic pituitary gonadal (HPG) axes. Dysregulations in these endocrine axes are related to mood disorders and as such it should not come as a major surprise that pregnancy and the postpartum period can have profound effects on maternal mood. Indeed, pregnancy and postpartum are associated with an increased risk for developing depressive symptoms in women. Postpartum depression affects approximately 10–15% of women and impairs mother–infant interactions that in turn are important for child development. Maternal attachment, sensitivity and parenting style are essential for a healthy maturation of an infant's social, cognitive and behavioral skills and depressed mothers often display less attachment, sensitivity and more harsh or disrupted parenting behaviors, which may contribute to reports of adverse child outcomes in children of depressed mothers. Here we review, in honor of the “father of motherhood”, Jay Rosenblatt, the literature on postnatal depression in the mother and its effect on mother–infant interactions. We will cover clinical and pre-clinical findings highlighting putative neurobiological mechanisms underlying postpartum depression and how they relate to maternal behaviors and infant outcome. We also review animal models that investigate the neurobiology of maternal mood and disrupted maternal care. In particular, we discuss the implications of endogenous and exogenous manipulations of glucocorticoids on maternal care and mood. Lastly we discuss interventions during gestation and postpartum that may improve maternal symptoms and behavior and thus may alter developmental outcome of the offspring.     

Weakened Resilience in Parenting Self-Efficacy in Pregnant Women Who Were Abused in Childhood: An Experimental Test

This study tested experimentally whether the combination of a history of childhood abuse and confrontation with difficult infant temperament is associated with negative changes in parenting self-efficacy. First-time pregnant women (N = 243) participated in the Adult Attachment Interview, which was used to assess the occurrence of abuse by parents in childhood and unresolved representations, and completed a task asking them to respond to infant cries. Sixty of the 243 participants (25%) experienced childhood abuse, mostly physical or sexual. The task simulated infant temperamental difficulty by manipulating soothing success in order to reflect an easy-to-soothe (80% soothing success) and a difficult-to-soothe infant (20% soothing success). Both after baseline and after each of the two stimulus series women assessed their parenting self-efficacy. Women who reported childhood abuse did not differ from women who reported no childhood abuse in parenting self-efficacy at baseline or in response to the easy-to-soothe infant (relative to baseline), but decreased more in parenting self-efficacy following the difficult-to-soothe infant. Effects did not vary according to resolution of trauma. These findings suggest that in response to infant temperamental difficulty, women who experienced childhood abuse may more easily lose confidence in their parenting abilities, which underlines the importance of preparing at-risk women for the possible challenges that come along with parenthood.     

Career and parenting satisfaction among medical students,residents and physician teachers at a Canadian medical school

BACKGROUND: Studies of career and parenting satisfaction have focused separately on medical students, residents and practising physicians. The objective of this study was to compare satisfaction across a spectrum of stages of medical career. METHODS: A survey of incoming medical students, current medical students, residents and physician teachers at the University of Saskatchewan was conducted in the spring of 1997. Response rates were 77% (43/56), 81% (177/218), 65% (134/206) and 39% (215/554) respectively. Factors assessed in the stepwise regression analysis were the effect of sex, parenting and level of training on the likelihood of recommending parenting to medical students or residents, and on parenting dissatisfaction, job dissatisfaction, career dissatisfaction and the importance of flexibility within the college program to accommodate family obligations. RESULTS: More male than female physician teachers had partners (92% v. 81%, p < 0.01) and were parents (94% v. 72%, p < 0.01). Female physician teachers spent equal hours per week at work compared with their male counterparts (mean 52 and 58 hours respectively) and more than double the weekly time on family and household work (36 v. 14 hours, p < 0.01). Physician teachers were the most likely respondents to recommend parenting to residents and their peers. Residents were the most dissatisfied with their parenting time. At all career stages women were less likely than men to recommend parenting, were more dissatisfied with the amount of time spent as parents and were more likely to regard flexibility within the college program as beneficial. There were no sex-related differences in job dissatisfaction and career dissatisfaction. However, married women were more dissatisfied with their jobs than were married men. Job dissatisfaction was greatest among medical students, and career dissatisfaction was greatest among residents. INTERPRETATION: The optimal timing of parenthood appears to be upon completion of medical training. Women were less likely to recommend parenting, less satisfied with the time available for parenting and more likely to value flexibility within the college program to accommodate family needs. These differences did not translate into women experiencing more job or career dissatisfaction.     

Childhood Neglect,Attachment to Companion Animals,and Stuffed Animals as Attachment Objects in Women and Men

ABSTRACT

Childhood neglect has severe, pervasive, negative outcomes that often continue into adulthood. As a potential source of support for both children and adults, companion animals (pets) can both give and receive affection and therefore may be sources of healthy attachment for people who were raised in negative situations. Toy stuffed animals, in contrast, can only receive affection but may still be useful as transitional objects, particularly for people who experienced interpersonal neglect in childhood and who are in the midst of a transition away from the family home and into college. The current study examined the relationships among childhood neglect, companion animal attachment, and attachment to toy stuffed animals. Undergraduate participants (n = 457) from a large regional university answered questionnaires online. The first hypothesis, that self-reported childhood neglect would be positively related to attachment to companion animals, was supported for women only. Neglected women were more attached to companion animals than were non-neglected women, with a medium effect size. For men, there was no significant effect. The second hypothesis was that childhood neglect would be positively related to attachment to stuffed animals; this hypothesis was not supported. The third hypothesis, that women would be more attached to both companion animals and stuffed animals than would men, was supported. Attachment to companion animals and attachment to stuffed animals were positively related. Results are discussed within a framework of attachment and transitional objects as potential aids to therapy in people who were neglected in childhood.     

Gender Differences in Owners Interacting with Pet Dogs: An Observational Study

Many studies show that people form strong affectional bonds with their dogs, treating them like family members or children. The present study investigates differences between women and men owners during interactions with their dogs, in a situation designed to investigate attachment and, thus, to promote emotional and affective responses: the Ainsworth's Strange Situation. Twenty‐five dog owners, 10 men and 15 women, were observed during free interactions with their pets in an adapted version of the ‘strange situation procedure’. Their behaviour towards their pets was videorecorded. Talking to the dog was evaluated together with the occurrence of affiliative and play behaviours. The owner's level of attachment to the dog was assessed using a questionnaire. Women and men differed in the use of verbal communication. Women talked more than men and had a shorter latency in starting talking. Their utterances resembled more closely infant‐directed speech or ‘motherese’. In contrast, there were no clear gender differences in affiliative and play behaviours. Both women and men engaged in play with their dogs and provided physical comfort. No differences emerged in the level of attachment reported by women and men owners in the questionnaire. These data support the hypothesis that the behaviour of modern pet owners towards their dogs is an interspecific parental behaviour, and suggest that behaviours evolved to provide care and comfort to human infants have been co‐opted for interacting with other social partners. The difference in verbal communication between women and men is in agreement with an evolutionary scenario suggesting a greater pre‐disposition in women to use language as a relational tool.     

The neurobiology of mammalian parenting and the biosocial context of human caregiving

This article is part of a Special Issue “Parental Care”. Research on the neurobiology of attachment, pioneered by scholars in the generation that followed the discovery of social bonding, examined the biological basis of mammalian parenting through systematic experiments in animal models and their application to theories on human attachment. This paper argues for the need to construct a theory on the neurobiology of human attachment that integrates findings in animal models with human neuroscience research to formulate concepts based on experimental, not only extrapolative data. Rosenblatt's (2003) three characteristics of mammalian parenting – rapid formation of attachment, behavioral synchrony, and mother-offspring attachment as basis of social organization – are used to guide discussion on mammalian-general versus human-specific attributes of parental care. These highlight specific components of attachment in rodents, primates, and humans that chart the evolution from promiscuous, nest-bound, olfactory-based bonds to exclusive, multi-sensory, and representation-based attachments. Following, three continua are outlined in parental behavior, hormones, and brain, each detailing the evolution from rodents to humans. Parental behavior is defined as a process of trophallaxis – the reciprocal multisensory exchange that supports approach orientation and enables collaboration in social species – and includes human-specific features that enable behavioral synchrony independent of tactile contact. The oxytocin system incorporates conserved and human-specific components and is marked by pulsatile activity and dendritic release that reorganize neural networks on the basis of species-specific attachment experiences. Finally, the subcortical limbic circuit underpinning mammalian mothering extends in humans to include multiple cortical networks implicated in empathy, mentalizing, and emotion regulation that enable flexible, goal-directed caregiving. I conclude by presenting a philosophical continuum from Hobbes to Lorenz, which illustrates how research on the neurobiology of attachment can put in the forefront the social-collaborative elements in human nature and afford a new perspective on the mind-brain polarity.     

The development of gender-related behavior in females following prenatal exposure to diethylstilbestrol (DES)

Animal research has shown that diethylstilbestrol (DES) present during the sensitive developmental periods of the hypothalamus and adjacent areas of the brain affects the development of sex-dimorphic brain structures and subsequent behavior. To test for corresponding behavioral effects in humans, 30 women with a history of prenatal DES exposure were contrasted with 30 unexposed women who had been referred to the same clinic for a colposcopic examination because of an abnormal Pap smear. Gender-role behavior of childhood, adolescence, and adulthood was assessed by means of a semistructured interview, the Gender Role Assessment Schedule-Adult, and the Bem Sex Role Inventory. The mothers of these women were interviewed about their daughters with the "mother form" of the same interview schedule. The results suggest that DES women show less orientation toward parenting than the controls. There were no consistent group differences in other domains of gender-role behavior.     

Separation Anxiety,Attachment and Inter-Personal Representations: Disentangling the Role of Oxytocin in the Perinatal Period

In this paper, we aimed to assess cross-sectionally and longitudinally associations between disturbances in maternal early attachment experiences, symptoms of separation anxiety and depression and oxytocin plasma levels. We examined a mediational model that tested the hypothesis that anxious attachment style arising from the mothers’ early bonding experiences with her own parents was associated with high levels of separation anxiety which, via its impact on depression, was associated with reduced levels of oxytocin in the postnatal period. Data is reported on a structured sample of 127 women recruited during pregnancy from a general hospital antenatal clinic and an initial follow up cohort of 57 women who were re-assessed at 3-months post-partum. We found an association between lower oxytocin level in the post partum period and symptoms of separation anxiety and depression during pregnancy, as well as maternal negative interpersonal representations, upbringing attributes and anxious attachment style. Further meditational analysis revealed that the unique association between anxious attachment and depression is mediated by separation anxiety and that depressed mood mediated the relationship between separation anxiety and oxytocin. In conjunction with evidence from the literature suggesting that lower oxytocin level is associated with bonding difficulties, our findings have significant implications for understanding the biological processes underpinning adverse attachment experiences, negative affect state, and mother-to-infant bonding difficulties.     

Pathogenesis of urinary tract infection in the elderly: the role of bacterial adherence to uroepithelial cells

The in vitro adherence of nine strains of Gram-negative bacteria to uroepithelial cells from 24 women patients (>65 years) was significantly higher than to cells from 24 premenopausal women (18–40 years). Uroepithelial cells from patients with a history of previous urinary tract infection (UTI) were marginally more receptive to attachment of uropathogens than cells from women without a history of UTI, but this was not statistically significant. Serum from four elderly women with asymptomatic bacteriuria was used to stabilize samples for electron-microscopic examination, which showed the presence of fibrous glycocalyx material surrounding the bacteria and attached to the uroepithelial cells. Eighty uropathogenic isolates from elderly and premenopausal women were found to express adhesins, to produce urease and hemolysins, and to ferment sucrose, salicin, and dulcitol. These results suggest that the increased receptivity of uroepithelial cells to bacterial attachment may be a predisposing factor in the onset of UTI in the hospitalized and domiciliary elderly population.     

Parenting interventions to promote early child development in the first three years of life: A global systematic review and meta-analysis

BackgroundParents are the primary caregivers of young children. Responsive parent–child relationships and parental support for learning during the earliest years of life are crucial for promoting early child development (ECD). We conducted a global systematic review and meta-analysis to evaluate the effectiveness of parenting interventions on ECD and parenting outcomes.Methods and findingsWe searched MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, and Global Health Library for peer-reviewed, published articles from database inception until November 15, 2020. We included randomized controlled trials (RCTs) of parenting interventions delivered during the first 3 years of life that evaluated at least 1 ECD outcome. At least 2 reviewers independently screened, extracted data, and assessed study quality from eligible studies. ECD outcomes included cognitive, language, motor, and socioemotional development, behavior problems, and attachment. Parenting outcomes included parenting knowledge, parenting practices, parent–child interactions, and parental depressive symptoms. We calculated intervention effect sizes as the standardized mean difference (SMD) and estimated pooled effect sizes for each outcome separately using robust variance estimation meta-analytic approaches. We used random-effects meta-regression models to assess potential effect modification by country-income level, child age, intervention content, duration, delivery, setting, and study quality. This review was registered with PROSPERO (CRD42018092458 and CRD42018092461). Of the 11,920 articles identified, we included 111 articles representing 102 unique RCTs. Pooled effect sizes indicated positive benefits of parenting interventions on child cognitive development (SMD = 0.32, 95% CI [confidence interval]: 0.23, 0.40, P < 0.001), language development (SMD = 0.28, 95% CI: 0.18 to 0.37, P < 0.001), motor development (SMD = 0.24, 95% CI: 0.15 to 0.32, P < 0.001), socioemotional development (SMD = 0.19, 95% CI: 0.10 to 0.28, P < 0.001), and attachment (SMD = 0.29, 95% CI: 0.18 to 0.40, P < 0.001) and reductions in behavior problems (SMD = −0.13, 95% CI: −0.18 to −0.08, P < 0.001). Positive benefits were also found on parenting knowledge (SMD = 0.56, 95% CI: 0.33 to 0.79, P < 0.001), parenting practices (SMD = 0.33, 95% CI: 0.22 to 0.44, P < 0.001), and parent–child interactions (SMD = 0.39, 95% CI: 0.24 to 0.53, P < 0.001). However, there was no significant reduction in parental depressive symptoms (SMD = −0.07, 95% CI: −0.16 to 0.02, P = 0.08). Subgroup analyses revealed significantly greater effects on child cognitive, language, and motor development, and parenting practices in low- and middle-income countries compared to high-income countries; and significantly greater effects on child cognitive development, parenting knowledge, parenting practices, and parent–child interactions for programs that focused on responsive caregiving compared to those that did not. On the other hand, there was no clear evidence of effect modification by child age, intervention duration, delivery, setting, or study risk of bias. Study limitations include considerable unexplained heterogeneity, inadequate reporting of intervention content and implementation, and varying quality of evidence in terms of the conduct of trials and robustness of outcome measures used across studies.ConclusionsParenting interventions for children during the first 3 years of life are effective for improving ECD outcomes and enhancing parenting outcomes across low-, middle-, and high-income countries. Increasing implementation of effective and high-quality parenting interventions is needed globally and at scale in order to support parents and enable young children to achieve their full developmental potential.

In a systematic review and meta-analysis, Joshua Jeong and colleagues study the effectiveness of parenting interventions in children 3 years and younger in promoting early childhood development and parenting outcomes.     

Endogenous estradiol levels are associated with attachment avoidance and implicit intimacy motivation

Estradiol has been linked with attachment and caregiving processes in humans and other mammals; however, relations between estradiol and personality constructs relevant to intimate relationships have not yet been explored. In the present sample of 100 adult participants (52 men, 48 women), we examined endogenous estradiol levels in relation to two personality constructs that predict comfort with and desire for close, intimate relationships—attachment style and implicit intimacy motivation. In both men and women, estradiol levels were predicted by an interaction between a dimension of attachment style—attachment avoidance—and implicit intimacy motivation. Specifically, the highest estradiol levels were observed among participants whose explicit traits support the expression of their implicit motives, that is, those characterized by both low avoidance and high intimacy motivation. Our findings provide novel evidence that endogenous estradiol levels are associated with relationship-relevant personality constructs in theoretically meaningful ways. These findings also highlight the importance of considering interactions between implicit and explicit personality constructs in the study of the biological bases of personality.     

Testosterone Levels Are Negatively Associated with Childlessness in Males,but Positively Related to Offspring Count in Fathers

Variation in testosterone (T) is thought to affect the allocation of effort between reproductive and parenting strategies. Here, using a large sample of elderly American men (n = 754) and women (n = 669) we examined the relationship between T and self-reported parenthood, as well as the relationship between T and number of reported children. Results supported previous findings from the literature, showing that fathers had lower T levels than men who report no children. Furthermore, we found that among fathers T levels were positively associated with the number of children a man reports close to the end of his lifespan. Results were maintained when controlling for a number of relevant factors such as time of T sampling, participant age, educational attainment, BMI, marital status and reported number of sex partners. In contrast, T was not associated with either motherhood or the number of children women had, suggesting that, at least in this sample, T does not influence the allocation of effort between reproductive and parenting strategies among women. Findings from this study contribute to the growing body of literature suggesting that, among men, pair bonding and paternal care are associated with lower T levels, while searching and acquiring sex partners is associated with higher T levels.     

Arginine vasopressin 1a receptor gene and maternal behavior: evidence of association and moderation

This study examined associations among maternal sensitivity, mothers' early adversity and the Arginine Vasopressin 1a Receptor (AVPR1A) gene. Early adversity in mothers' background has been found to be associated with lower maternal sensitivity. Animal literature suggests that variation in the AVPR1A gene is associated with parenting quality. The goal of the study was to examine the role of the AVPR1A gene in maternal sensitivity, especially under conditions of high early adversity. Participants included 151 Caucasian women from a community sample. The women were videotaped in their home while interacting separately with two of their children (target child = 18 months, older sibling <6 years). Evidence was found for an association between the AVPR1A gene and maternal sensitivity. Mothers with two copies of the long RS3 alleles were less sensitive than mothers with one or zero copies of the long alleles. This association was strongest under conditions of high maternal early adversity.     

Interactions of mothers and nurses with premature infants.

The initial attachment of three mothers to three premature infants weighing less than 1500 g was assessed by observation of the mother''s behaviour during visits to her child in the hospital nursery. Interactions of mothers and infants were compared with those of nurses and infants. Premature infants, during a stay in hospital of approximately 7 weeks, have to adapt to up to 70 different nurses and receive generally little contact stimulation from them. Mothers change in their interactional behaviour over time but show persistent individual differences in amount of touching, smiling and talking to their infants. Follow-up investigation will determine if the maternal behaviour as demonstrated in the nursery is predictive of later parenting disorders.     

Attachment,Mothering and Mental Illness: Mother–Infant Therapy in an Institutional Context

This paper is an ethnographic exploration of how attachment theory underpins therapeutic practices in an Australian institutional context where mothers of infants have been diagnosed and are undergoing treatment for mental illness. We argue that attachment theory in this particular context rests on a series of principles or assumptions: that attachment theory is universally applicable; that attachment is dyadic and gendered; that there is an attachment template formed which can be transferred across generations and shapes future social interactions; that there is understood to be a mental health risk to the infant when attachment is characterised as problematic; and that this risk can be mitigated through the therapeutic practices advocated by the institution. Through an in-depth case study, this paper demonstrates how these assumptions cohere in practice and are used to assess mothering as deficient, to choose therapeutic options, to shape women’s behaviour, and to formulate decisions about child placement.     

Coercive restraint therapies: a dangerous alternative mental health intervention

Physicians caring for adopted or foster children should be aware of the use of coercive restraint therapy (CRT) practices by parents and mental health practitioners. CRT is defined as a mental health intervention involving physical restraint and is used in adoptive or foster families with the intention of increasing emotional attachment to parents. Coercive restraint therapy parenting (CRTP) is a set of child care practices adjuvant to CRT. CRT and CRTP have been associated with child deaths and poor growth. Examination of the CRT literature shows a conflict with accepted practice, an unusual theoretic basis, and an absence of empirical support. Nevertheless, CRT appears to be increasing in popularity. This article discusses possible reasons for the increase, and offers suggestions for professional responses to the CRT problem.     

Lesbian health care. What a primary care physician needs to know.

Many primary care physicians take care of lesbians and women sexually active with women without being aware of their patients'' sexual orientation. These women have unique medical and psychosocial needs that each physician must consider. Lesbian identity or being sexually active exclusively with women influences care in areas such as sexually transmitted diseases, risk of human immunodeficiency virus infection, counseling, cancer risk, screening, parenting, depression, alcohol use, and violence. We review an approach to taking a history with all women that facilitates open, comfortable communication with lesbians. We also review specific medical and psychosocial areas of primary care in which caring for lesbians is different from caring for other women. Further research is needed on lesbian health issues to provide appropriate guidelines to clinicians.     

Towards a Model of Contemporary Parenting: The Parenting Behaviours and Dimensions Questionnaire

The assessment of parenting has been problematic due to theoretical disagreement, concerns over generalisability, and problems with the psychometric properties of current parenting measures. The aim of this study was to develop a comprehensive, psychometrically sound self-report parenting measure for use with parents of preadolescent children, and to use this empirical scale development process to identify the core dimensions of contemporary parenting behaviour. Following item generation and parent review, 846 parents completed an online survey comprising 116 parenting items. Exploratory and confirmatory factor analyses supported a six factor parenting model, comprising Emotional Warmth, Punitive Discipline, Anxious Intrusiveness, Autonomy Support, Permissive Discipline and Democratic Discipline. This measure will allow for the comprehensive and consistent assessment of parenting in future research and practice.     

Negotiated Bonds: The Practice of Childfree Pet Parenting

The American Pet Products Association reports a decade-long increase of pet spending, estimated to reach over $69 billion in 2017. In some cases, these owners apply traditional parenting practices while nurturing their pets. Relatedly, a growing number of pet owners identify themselves as “pet parents.” This study is the first known work to investigate how identity plays a role in the growing population of pet parents. While previous research into the pet parenting phenomenon has sought to quantify the demographics, spending, and frequency of this population, less work seeks to understand what pet parenting looks like in practice. Sampling a population of childfree pet parents, the current study utilized semi-structured interviews and identified two common themes in their daily practice of the identity: 1) Despite the use of parent–child terms and strategies, childfree pet parents are acutely aware of the differences between raising children and raising pets, and 2) pet parents ascribe agency to their pet, identifying individual pet wants and needs to fulfill. This may further inform future research on human–animal relationships by establishing a human identity that connects directly to pet practices in the United States, asking us to consider the lived experiences of this growing population and their pets including spending, lifestyle, and attachment concerns.
