The first 20,000 strange situation procedures: A meta-analytic review.
A programmatic set of meta-analyses by Groh et al. (e.g., Groh et al., 2017a) and Madigan et al. (e.g., Madigan et al., 2023) demonstrated that secure child-caregiver attachments are positively associated with children’s social and emotional development, with somewhat stronger associations identified in relation to social competence and (lower) externalizing behaviors than for (lower) internalizing symptoms (Groh et al., 2017a). The association of attachment security with children’s cognitive and language outcomes, however, is relatively less well established. More- over, it is unknown whether attachment is associated with these outcomes through direct links, indirect links (i.e., as a mediator of the association between caregiver sensitivity and child cognition and language processes), or both. Empirical tests of these hypotheses have not yet been conducted. The current study had two main objectives: 1) provide a meta-analytic update for the association between attachment security and cognition and language (k = 125 studies [107 samples]; N = 9,213 children; 52.5% boys; 100% mothers; 93% from North America/Europe), and 2) test this association within a larger mediation model that accounts for the roles of sensitivity and attachment through a meta-analytic structural equation model (sensitivity → attachment → cognitive and language outcomes). Results showed that child-mother attachment security was significantly associated with child cognition (r = 0.17, 95% CI [0.14, 0.20]) and language outcomes (r = 0.16, 95% CI [0.12, 0.20]). The MASEM model revealed a small, but significant, indirect effect of sensitivity on cognitive and language outcomes through attachment security. The discussion considers the theoretical and practical implications of these findings.
This meta-analysis synthesized the distribution of attachment classifications as coded with the Cassidy-Marvin Preschool Attachment Coding System and the Main-Cassidy Six-Year-Old System. These systems have extended scholars’ capacity to measure differences in the developing child-parent attachment relationship, and its sequelae, beyond the infancy period; however, the global distribution of the attachment categories in these systems, and the potential factors influencing this distribution, remain unknown. The meta-analysis included 97 samples (N = 8,186 children; 55% boys), mostly drawn from North American or European populations (89%; M = 76% White). Results indicated that the distribution of child-mother attachment was 53.5% secure, 14.0% avoidant, 11.0% ambivalent, and 21.5% disorganized/controlling. Moderator analyses showed that rates of security were lower, and rates of disorganization were higher, in samples of at-risk families, specifically when children were exposed to maltreatment. Variations in the procedure also moderated the distribution. The discussion calls for greater unity around methodological practices.
The strange-situation procedure was given to 60 pairs of Japanese mothers and infants, and their results were compared with those of Ainsworth. There were no significant differences in proportions of securely attached (68%) and insecurely attached (32%) infants between the countries. Degrees and patterns of interactive behaviors in each type were also similar. However, the Japanese insecure group consisted of only C types, and there were no A types. About half of the C-type infants behaved inconsistently: They behaved like B-type infants in Episodes 2–5 and like C-type ones thereafter. These findings were interpreted in terms of the excessive stress caused by the procedure as well as Japanese child-rearing customs fostering the attachment to the mother. Two strategies are proposed for getting richer information from the procedure in different cultures: multiple classification of varying stress levels and cultural examination of the diagnostic value of each behavior as a classificatory cue.
Although numerous individual studies have attempted to link child-parent attachment and prosociality, a systematic picture of that relation requires a meta-analytic approach that considers different dimensions of prosociality and potential moderators. The current meta-analysis examined 41 studies drawn primarily from North America and Europe and published between 1978 to 2020. Child age ranged from 12 to 53 months at the child-parent attachment assessment, and 12 to 108 months at the assessment of prosociality. Across 35 studies (100 effect sizes, N = 4,611), child-mother attachment security and child prosociality were significantly associated (r = .19, 95% CI [.14, .23]). No moderators were identified. Exploratory estimates were also derived for subtypes of child-mother attachment insecurity. Across 6 studies (8 effect sizes, N = 402), child-father attachment security was significantly associated with prosociality (r = .11, 95% CI [.02, .23]. The magnitude of effect sizes did not differ based on parent gender. The discussion considers areas of growth for attachment and prosociality research.
Improving parenting, child attachment, and externalizing behaviors: Meta-analysis of the first 25 randomized controlled trials on the effects of Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD). VIPP-SD combines support of parental sensitive responsiveness with coaching parents in sensitive limit setting. Here, we present meta-analyses of 25 RCTs conducted with more than 2,000 parents and caregivers. Parents or children had various risks. We examined its effectiveness in promoting parental cognitions and behavior regarding sensitive parenting and limit setting, in promoting secure child–parent attachment, and reducing externalizing child behavior. Web of Science, MEDLINE, PubMed, and recent reviews were searched for relevant trials (until May 10, 2021). Multilevel meta-analysis with META, METAFOR, and DMETAR in R took account of the 3-level structure of the datasets (studies, participants, measures). The meta-analyses showed substantial combined effect sizes for parenting behavior ( r = .18) and attitudes ( r = .16), and for child attachment security ( r = .23), but not for child externalizing behavior ( r = .07). In the subset of studies examining effects on both parenting and attachment, the association between effect sizes for parenting and for attachment amounted to r = .48. We consider the way in which VIPP-SD uses video-feedback an active intervention component. Whether VIPP-SD indeed stimulates secure attachment through enhanced positive parenting remains an outstanding question for further experimental study and individual participant data meta-analysis.
This study examined whether maternal disrupted communication, which is associated with disorganized infant attachment, also characterizes mothers of ambivalent infants. The study, conducted in Israel, included a Jewish sample (N = 163; 68 Girls) from diverse socioeconomic status, collected between 1991 and 1993 in an earlier study. The sample over‐represented ambivalent and disorganized attachments. Attachment was assessed in the Strange Situation Procedure (SSP) at 12 months and disrupted communication was coded from the SSP using the Atypical Maternal Behavior Instrument for Assessment and Classification (AMBIANCE; Lyons‐Ruth et al., 1999). Mothers of ambivalent infants showed higher disrupted communication than mothers of secure, avoidant, and disorganized infants. The findings shed further light on the correlates of ambivalent attachment and call for research regarding maternal and infant characteristics that differentiate ambivalent versus disorganized attachment.
This paper prospected the evidence synthesized in meta-analyses on child-parent attachment to discuss its implications for the future of attachment research. Based on the 75 identified meta-analyses, effect size benchmarks may need to be adjusted to small (r = .10), medium (r = .20), and large (r = .30). Topics of attachment meta-analyses predominantly (53%) reflected interest in testing theory. Bibliometric analysis of scientific publications (k = 7,595) that cited these meta-analyses reflect waxing uptake in work on interventions, mental health, and attachment anxiety/avoidance and waning uptake in work on attachment relationships and representations, except for the subtopics of sensitivity and fathers. Prospects for scientifically rigorous research are to be found in engagement with stakeholders working to address important societal challenges. Promoting nurturing care and reducing harm in child welfare contain "Goldilocks-problems" that are amenable to incremental progress while simultaneously advancing theory and methods.
Attachment theory and research are drawn upon in many applied settings, including family courts, but misunderstandings are widespread and sometimes result in misapplications. The aim of this consensus statement is, therefore, to enhance understanding, counter misinformation, and steer family-court utilisation of attachment theory in a supportive, evidence-based direction, especially with regard to child protection and child custody decision-making. The article is divided into two parts. In the first, we address problems related to the use of attachment theory and research in family courts, and discuss reasons for these problems. To this end, we examine family court applications of attachment theory in the current context of the best-interest-of-the-child standard, discuss misunderstandings regarding attachment theory, and identify factors that have hindered accurate implementation. In the second part, we provide recommendations for the application of attachment theory and research. To this end, we set out three attachment principles: the child’s need for familiar, non-abusive caregivers; the value of continuity of good-enough care; and the benefits of networks of attachment relationships. We also discuss the suitability of assessments of attachment quality and caregiving behaviour to inform family court decision-making. We conclude that assessments of caregiver behaviour should take center stage. Although there is dissensus among us regarding the use of assessments of attachment quality to inform child custody and child-protection decisions, such assessments are currently most suitable for targeting and directing supportive interventions. Finally, we provide directions to guide future interdisciplinary research collaboration.
Cornerstones of Attachment Research [ free to download ] re-examines the work of key laboratories that have contributed to the study of attachment. In doing so, the book traces the development in a single scientific paradigm through parallel but separate lines of inquiry. Chapters address the work of Bowlby, Ainsworth, Main and Hesse, Sroufe and Egeland, and Shaver and Mikulincer. Cornerstones of Attachment Research utilises attention to these five research groups as a lens on wider themes and challenges faced by attachment research over the decades. The chapters draw on a complete analysis of published scholarly and popular works by each research group, as well as much unpublished material.
In this article, we present a tool and a method for measuring the psychological and cultural distance between societies and creating a distance scale with any population as the point of comparison. Because psychological data are dominated by samples drawn from Western, educated, industrialized, rich, and democratic (WEIRD) nations, and overwhelmingly, the United States, we focused on distance from the United States. We also present distance from China, the country with the largest population and second largest economy, which is a common cultural comparison. We applied the fixation index ( F ST ), a meaningful statistic in evolutionary theory, to the World Values Survey of cultural beliefs and behaviors. As the extreme WEIRDness of the literature begins to dissolve, our tool will become more useful for designing, planning, and justifying a wide range of comparative psychological projects. Our code and accompanying online application allow for comparisons between any two countries. Analyses of regional diversity reveal the relative homogeneity of the United States. Cultural distance predicts various psychological outcomes.
Does psychopathology develop as a function of the objective or subjective experience of childhood maltreatment? To address this question, we studied a unique cohort of 1,196 children with both objective, court-documented evidence of maltreatment and subjective reports of their childhood maltreatment histories made once they reached adulthood, along with extensive psychiatric assessment. We found that, even for severe cases of childhood maltreatment identified through court records, risk of psychopathology linked to objective measures was minimal in the absence of subjective reports. In contrast, risk of psychopathology linked to subjective reports of childhood maltreatment was high, whether or not the reports were consistent with objective measures. These findings have important implications for how we study the mechanisms through which child maltreatment affects mental health and how we prevent or treat maltreatment-related psychopathology. Interventions for psychopathology associated with childhood maltreatment can benefit from deeper understanding of the subjective experience. In a cohort of 1,196 children followed to age 29 years, the authors found that risk of psychopathology was more strongly associated with subjective recall of childhood maltreatment histories than with objective, court-documented evidence of maltreatment.
Background
Maternal depression and anxiety have been associated with deleterious child outcomes. It is, however, unclear how the chronicity and timing of maternal mental health problems predict child development outcomes. The aim of the current study was to assess the effect of both chronicity and timing of maternal anxiety and depression in pregnancy, infancy, and the toddler period on children's internalizing and externalizing symptoms, as well as social and communication skills at age 5.
Method
Participants were 1,992 mother–child pairs drawn from a large prospective pregnancy cohort. Mothers reported on anxiety and depression symptoms with clinical screening tools at six time points between <25 weeks gestation and 3 years postpartum. Child outcomes were assessed at age 5.
Results
Effect sizes were small for brief incidents of depression/anxiety and increased for intermittent and chronic problems (i.e., three or more timepoints) compared with mothers who had never experienced clinical‐level anxiety or depression. Maternal anxiety/depression during pregnancy, infancy, and toddlerhood predicted all child outcomes, even after controlling for depression/anxiety during the other timepoints. However, maternal anxiety and depression during toddlerhood had a stronger association with child internalizing/externalizing symptoms and communication skills than either prenatal or postpartum depression/anxiety.
Conclusions
Increasing number of exposures to clinical‐level anxiety and depression is related to poorer child outcomes. Neither prenatal nor postpartum periods emerged as “sensitive” periods. Rather, maternal depression and anxiety during toddlerhood was more strongly associated with child outcomes at age 5. Results highlight the need for continued support for maternal mental health across early childhood.
The field of psychology prides itself on being a data-driven science. In 2008, however, Arnett brought to light a major weakness in the evidence on which models, measures, and theories in psychology rest. He demonstrated that the most prominent journals in six subdisciplines of psychology focused almost exclusively (over 70% of samples and authors) on a cultural context, the United States, shared by only 5% of the world's population. How can psychologists trust that these models and results generalize to all humans, if the evidence comes from a small and unrepresentative portion of the global population? Arnett's analysis, cited over 1,300 times since its publication, appears to have galvanized researchers to think more globally. Social scientists from the United States have increasingly sought ways to collaborate with colleagues abroad. Ten years later, an analysis of the same 6 journals for the period of 2014 to 2018 indicates that the authors and samples are now on average a little over 60% American based. The change is mainly due to an increase in authorship and samples from other English-speaking and Western European countries. Thus, it might be said that 11% of the world's population is now represented in these top psychology journals, but that 89% of the world's population continues to be neglected. Majority world authors and samples (4-5%) are still sorely lacking from the evidence base. Psychology still has a long way to go to become a science truly representative of human beings. Several specific recommendations are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
Generations of researchers have tested and used attachment theory to understand children’s development. To bring coherence to the expansive set of findings from small-sample studies, the field early on adopted meta-analysis. Nevertheless, gaps in understanding intergenerational transmission of individual differences in attachment continue to exist. We discuss how attachment research has been addressing these challenges by collaborating in formulating questions and pooling data and resources for individual-participant-data meta-analyses. The collaborative model means that sharing hard-won and valuable data goes hand in hand with directly and intensively interacting with a large community of researchers in the initiation phase of research, deliberating on and critically reviewing new hypotheses, and providing access to a large, carefully curated pool of data for testing these hypotheses. Challenges in pooling data are also discussed.
Children with callous–unemotional (CU) traits and children with disorganized attachment patterns are at heightened risk of poor psychological outcomes but little is known about the overlap between these constructs and their unique contributions to conduct problems in early childhood. This study examined associations between CU traits, disorganized attachment, and conduct problem (CP) severity in a sample of clinic-referred toddlers with behavioral problems. Mother–child dyads (n = 56; mean child age 19.50 months) completed parent-report questionnaires, a dyadic play session, and the Strange Situation Procedure to assess child attachment pattern. Significant positive associations were found between CU traits and disorganized attachment, independent of CP severity. CU traits but not disorganized attachment predicted CP severity. Results indicate that among toddlers with clinic-referred disruptive behavior problems, there are clear links between CU traits and attachment disorganization. Of the two constructs, however, CU traits appear to be most salient in the expression of CPs.
As a result of societal changes, fathers participate more actively in child care than they used to. In this article, we propose a context‐dependent biobehavioral model of emergent fatherhood in which sociocultural, behavioral, hormonal, and neural factors develop and interact during the first 1,000 days of fatherhood. Sociocultural factors, including different expectations of fathers and varying opportunities for paternal caregiving through paid paternal leave, influence paternal involvement. Levels of hormones (e.g., testosterone, vasopressin, oxytocin, cortisol) predict fathers’ parenting behaviors, and involvement in caregiving in turn affects their hormones and brain responses to infant stimuli. The birth of the first child marks the transition to fatherhood and may be a critical period in men’s lives, with a smoother transition to fatherhood predicting more optimal involvement by fathers in subsequent years. A focus on prenatal and early postnatal fathering may pave the way for developing interventions that effectively support fathering during pregnancy and in the first years of their children’s lives.
Introduction:
Scientific evidence gathered over the last decades has demonstrated that early attachment is a vital process for the understanding, prevention, and intervention of people's mental and physical health. However, information about the attachment system functioning in Chile is scarce.
Objective:
To des cribe attachment styles distribution in populations of children under different types of care.
Subjects and method:
Through a retrospective descriptive method, 714 mother-child pairs (1 to 36 months- old) selected at random and purposefully, were assessed using the Strange Situation Procedure, Atta chment during Stress Scale (ADS), and Student-Teacher Relationship Scale. The samples were collec ted from randomly selected normative families, infants attending JUNJI nurseries and kindergartens, and infants from CONIN centers and who live in prison with their mothers.
Results:
The samples from six studies show the spectrum of the attachment system functioning in diverse conditions: 70% secure and 30% insecure, and 51.1% secure and 48.9% insecure in normative samples; 48.5% secure and 51.5% in secure in alternative care; 39.6% secure and 60.4% insecure, and 25% secure and 75% in secure styles in high-risk samples.
Conclusion:
the study presents interesting evidence on the atta chment distributions in childhood, which allow reflecting on the uneven Chilean reality with regard to early social and emotional development.
This randomized controlled trial investigated the efficacy of Attachment and Biobehavioral Catch-up (ABC; Dozier, Bick, & Bernard, 2011) in reducing disrupted parenting behavior (affective communication errors, role/boundary confusion, fearful/disoriented, intrusive/negativity, and withdrawal) and its association with disorganized attachment. Participants were 105 mother-child dyads randomized to receive either ABC or a control intervention (a 10-session home-visiting intervention focused on improving children's cognitive abilities, gross and fine motor abilities, and language development). At the time of study enrollment, mothers were approximately 26.7 years old (SD = 7.8) and predominantly Black or African American (73.9%). At the first follow-up visit, children were approximately 20.7 months old (SD = 6.3) and most were identified as Black or African American (61.9%). Fifty-two percent of children were male (n = 55). Assessments of disrupted parenting behavior and child attachment quality were assessed approximately 7 months postintervention (SD = 5.8). A one-way analysis of variance revealed that parents who received ABC demonstrated lower levels of parental withdrawal than parents who received the control condition. A structural equation model revealed a significant indirect effect of intervention group on attachment quality through lower levels of parental withdrawal. Results add to the efficacy of the ABC intervention and identified parental withdrawal as a mediator of change.
The current study investigated the intergenerational transmission of attachment in Sapporo, Japan, using the Adult Attachment Interview (AAI) and the Strange Situation Procedure (SSP). This is the first SSP study in Sapporo in three decades, after a study in the mid-1980s reported controversial results. The SSP distributions found in the current study, however, were similar to those reported in the earlier Sapporo study, including its controversial finding that ambivalent attachment was predominant in insecure infants. The current study used the AAI and the SSP to study the intergenerational transmission of attachment in Japan and found a strong categorical match consistent with those reported elsewhere in the world. A proportion of infants who were judged disorganized as the first report in this Japanese sample was also found to be similar to the reported global norm. Disorganized attachment in Japanese infants was strongly predicted by the mother's unresolved state of mind as was found across normative samples.

In 1990, M. Main and J. Solomon introduced the procedures for coding a new “disorganized” infant attachment classification for the Ainsworth Strange Situation procedure (M.D.S. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978). This classification has received a high degree of interest, both from researchers and from child welfare and clinical practitioners. Disorganized attachment has primarily been understood through the lens of E. Hesse and M. Main's concept of “fright without solution,” taken to mean that an infant experiences a conflict between a desire to approach and flee from a frightening parent when confronted by the Strange Situation. Yet, looking back, it can be observed that the way Hesse and Main's texts were formulated and read has generated confusion; there have been repeated calls in recent years for renewed theory and clarification about the relationship between disorganization and fear. Responding to these calls, this article revisits the texts that introduced the idea of fright without solution, clarifying their claims through articulating more precisely the different meanings of the term fear. This clarified account will then be applied to consideration of pathways to infant disorganized behaviors.
Disorganized/Disoriented (D) attachment has seen widespread interest from policy makers, practitioners, and clinicians in recent years. However, some of this interest seems to have been based on some false assumptions that (1) attachment measures can be used as definitive assessments of the individual in forensic/child protection settings and that disorganized attachment (2) reliably indicates child maltreatment, (3) is a strong predictor of pathology, and (4) represents a fixed or static “trait” of the child, impervious to development or help. This paper summarizes the evidence showing that these four assumptions are false and misleading. The paper reviews what is known about disorganized infant attachment and clarifies the implications of the classification for clinical and welfare practice with children. In particular, the difference between disorganized attachment and attachment disorder is examined, and a strong case is made for the value of attachment theory for supportive work with families and for the development and evaluation of evidence-based caregiving interventions.
Major developments in attachment research over the past 2 decades have introduced parental mentalization as a predictor of infant-parent attachment security. Parental mentalization is the degree to which parents show frequent, coherent, or appropriate appreciation of their infants' internal states. The present study examined the triangular relations between parental mentalization, parental sensitivity, and attachment security. A total of 20 effect sizes (N = 974) on the relation between parental mentalization and attachment, 82 effect sizes (N = 6,664) on the relation between sensitivity and attachment, and 24 effect sizes (N = 2,029) on the relation between mentalization and sensitivity were subjected to multilevel meta-analyses. The results showed a pooled correlation of r = .30 between parental mentalization and infant attachment security, and rs of .25 for the correlations between sensitivity and attachment security, and between parental mentalization and sensitivity. A meta-analytic structural equation model was performed to examine the combined effects of mentalization and sensitivity as predictors of infant attachment. Together, the predictors explained 12% of the variance in attachment security. After controlling for the effect of sensitivity, the relation between parental mentalization and attachment remained, r = .24; the relation between sensitivity and attachment remained after controlling for parental mentalization, r = .19. Sensitivity also mediated the relation between parental mentalization and attachment security, r = .07, suggesting that mentalization exerts both direct and indirect influences on attachment security. The results imply that parental mentalization should be incorporated into existing models that map the predictors of infant-parent attachment. (PsycINFO Database Record
There is now ample evidence that the quality of early attachment experiences shapes expectations for supportive and responsive care and ultimately serves to scaffold adaptation to the salient tasks of development. Nonetheless, few studies have identified neural mechanisms that might give rise to these associations. Using a moderately large sample of low-income male participants recruited during infancy ( N = 171), we studied the predictive significance of attachment insecurity and disorganization at age 18 months (as measured in the Strange Situation Procedure) for patterns of neural activation to reward and loss at age 20 years (assessed during a reward-based task as part of a functional magnetic resonance imaging scan). Results indicated that individuals with a history of insecure attachment showed hyperactivity in (a) reward- and emotion-related (e.g., basal ganglia and amygdala) structures and (b) emotion regulation and self-referential processing (cortical midline structures) in response to positive and negative outcomes (and anticipation of those outcomes). Further, the neural activation of individuals with a history of disorganized attachment suggested that they had greater emotional reactivity in anticipation of reward and employed greater cognitive control when negative outcomes were encountered. Overall, results suggest that the quality of early attachments has lasting impacts on brain function and reward processing.
Although randomized interventions trials have been shown to reduce the incidence of disorganized attachment, no studies to date have identified the mechanisms of change responsible for such reductions. Maternal sensitivity has been assessed in various studies and shown to change with intervention, but in the only study to formally assess mediation, changes in maternal sensitivity did not mediate changes in infant security of attachment (Cicchetti, Rogosch, & Toth, 2006). Primary aims of the current randomized controlled intervention trial in a high-risk population were to fill gaps in the literature by assessing whether the intervention (a) reduced disorganization, (b) reduced disrupted maternal communication, and (c) whether reductions in disrupted maternal communication mediated changes in infant disorganization. The results indicated that, compared to controls ( n = 52), both infant disorganization and disrupted maternal communication were significantly reduced in the intervention group ( n = 65) that received regular home-visiting during pregnancy and the first year of life. Furthermore, reductions in disrupted maternal communication partially accounted for the observed reductions in infant disorganization compared to randomized controls. The results are discussed in relation to the societal cost effectiveness of early attachment-informed interventions for mothers and infants, as well as the importance of formally assessing underlying mechanisms of change in order to improve and appropriately target preventive interventions.
Disorganized attachment is associated with a host of negative developmental outcomes, leading to a growing interest in preventative interventions targeting the attachment relationship in infancy. The objective of this meta-analysis was to assess the effectiveness of interventions that aimed to prevent or reduce rates of disorganization among children at risk. We performed a literature search using PsycINFO, MEDLINE, and ProQuest databases for studies published between January 1989 and August 2016. All 16 studies (N = 1,360) included a control condition and reported postintervention rates of organized and disorganized attachments assessed by the Strange Situation Procedure. Results showed that, overall, interventions were effective in increasing rates of organized attachment compared to control conditions (d = 0.35, 95% CI [0.10-0.61]). Moderator analyses demonstrated that interventions were more effective (a) in more recently published studies than in older studies, (b) for maltreated samples than nonmaltreated samples, and (c) as children increased in age. These results have important implications for future development, tailoring, and implementation of attachment-based intervention programs.
This study is the first to examine infant-mother attachment in the Arab culture. Eighty-five Arab 1-year-old infants from Israel were observed in the strange situation, and maternal sensitivity was assessed from home observations. Supporting attachment theory's normativity hypothesis, no differences were found between the Arab-Israeli attachment distribution and Jewish-Israeli, Western, and non-Western distributions when examined at the two-way secure versus insecure level, although a few differences emerged when examined at the four-way ABCD level. Supporting the sensitivity hypothesis, mothers of secure infants were more sensitive than those of insecure infants but only in the case of Christian (and not Muslim) mothers. The findings provide support to attachment theory's generalizability but raise questions regarding the assessment of maternal sensitivity cross-culturally.
This meta-analytic review examines the association between early attachment (assessed at 1-5 years) and child temperament (assessed at birth-12 years), and compares the strength of this association with recently documented meta-analytic associations between early attachment and social competence, externalizing behavior, and internalizing symptoms. Based on 109 independent samples (N = 11,440) of diverse socioeconomic and ethnic backgrounds, temperament was weakly associated with attachment (in)security (d = .14, CI [0.08, 0.19]) but modestly associated with resistant attachment (d = .30, CI [0.21, 0.40]). Temperament was not significantly associated with avoidant (d = .10, CI [-0.02, 0.19]) or disorganized (d = .11, CI [-0.03, 0.25]) attachment. Across developmental domains, early attachment security was more strongly associated with social competence and externalizing behaviors than internalizing symptoms and temperament.
The early infant-mother attachment relationship is part of a network of close relationships in which the relationship between parents is especially relevant. Evidence for linkages between maternal satisfaction with the partner relationship and infant-mother attachment is equivocal. The current study tested whether associations between partner relationship dissatisfaction and infant-mother attachment quality might be conditional on mothers' parenting self-efficacy. The bivariate effect of partner relationship dissatisfaction on infant-mother attachment as well as moderation of this effect by parenting self-efficacy was tested in a sample of 260 infant-mother dyads 1 year after birth. There was no direct effect of partner dissatisfaction on attachment. Unexpectedly, for high parenting self-efficacy, greater partner dissatisfaction increased the odds of an avoidant infant attachment (compared with a disorganized) whereas, for low parenting self-efficacy, greater partner dissatisfaction decreased the odds of an avoidant infant attachment (compared with secure and disorganized). Findings underline the importance of parenting cognitions for understanding contextual factors of infant-mother attachment quality. (PsycINFO Database Record
This meta-analysis synthesized the distribution of attachment classifications as coded with the Cassidy-Marvin Preschool Attachment Coding System and the Main-Cassidy Six-Year-Old System. These systems have extended scholars’ capacity to measure differences in the developing child-parent attachment relationship, and its sequelae, beyond the infancy period; however, the global distribution of the attachment categories in these systems, and the potential factors influencing this distribution, remain unknown. The meta-analysis included 97 samples (N = 8,186 children; 55% boys), mostly drawn from North American or European populations (89%; M = 76% White). Results indicated that the distribution of child-mother attachment was 53.5% secure, 14.0% avoidant, 11.0% ambivalent, and 21.5% disorganized/controlling. Moderator analyses showed that rates of security were lower, and rates of disorganization were higher, in samples of at-risk families, specifically when children were exposed to maltreatment. Variations in the procedure also moderated the distribution. The discussion calls for greater unity around methodological practices.
Two meta‐analyses were conducted (N = 10,980 child–father dyads) with 93 studies published between 1983–2020, primarily in North America and Europe, on observed parental sensitivity to children (3–180 months; 48% girls; 14% non‐White) in partnered mothers and fathers. The first meta‐analysis found higher maternal mean levels of observed sensitivity, with a small effect size (d = −.27). Differences between parents were larger with micro coding and triadic/family assessments. Differences narrowed as a function of publication year and were not significant in European samples. The second meta‐analysis identified a moderate correlation between observed maternal and paternal sensitivity (r = .23 after adjusting for probable publication bias). Correlations were larger in Middle Eastern samples and with composite sensitivity scales.
An unsettled question in attachment theory and research is the extent to which children's attachment patterns with mothers and fathers jointly predict developmental outcomes. In this study, we used individual participant data (IPD) meta-analysis to assess whether early attachment networks with mothers and fathers are associated with children's internalizing and externalizing behavioral problems. Following a pre-registered protocol, data from 9 studies and 1,097 children (mean age: 28.67 months) with attachment classifications to both mothers and fathers were included in analyses. We used a linear mixed effects analysis to assess differences in children's internalizing and externalizing behavioral problems as assessed via the average of both maternal and paternal reports based on whether children had two, one, or no insecure (or disorganized) attachments. Results indicated that children with an insecure attachment relationship with one or both parents were at higher risk for elevated internalizing behavioral problems compared with children who were securely attached to both parents. Children whose attachment relationships with both parents were classified as disorganized had more externalizing behavioral problems compared to children with either one or no disorganized attachment relationship with their parents. Across attachment classification networks and behavioral problems, findings suggest (a) an increased vulnerability to behavioral problems when children have insecure or disorganized attachment to both parents, and (b) that mother-child and father-child attachment relationships may not differ in the roles they play in children's development of internalizing and externalizing behavioral problems.
This meta‐analytic study examined the associations between child‐father attachment in early childhood and children's externalizing and internalizing behavior problems. Based on 15 samples (N = 1,304 dyads), the association between child‐father attachment insecurity and externalizing behaviors was significant and moderate in magnitude (r = 0.18, 95% CI: 0.10, 0.27 or d = 0.37, 95% CI: 0.20, 0.55). No moderators of this association were identified. Based on 12 samples (N = 1,073), the association between child‐father attachment insecurity and internalizing behaviors was also significant, albeit smaller in magnitude (r = 0.09, 95% CI: 0.02, 0.15; or d = 0.17, 95% CI: 0.03, 0.31). Between‐study heterogeneity was insufficient to consider moderators. When compared to the effect sizes of prior meta‐analyses on child‐mother attachment and behavior problems, the quality of the attachment relationship with fathers yields a similar magnitude of associations to children's externalizing and internalizing behaviors. Results support the need to consider the role of the attachment network, which notably includes attachment relationships to both fathers and mothers, to understand how attachment relationships contribute to child development.
Early attachment has been commonly hypothesized to predict children’s future developmental outcomes, and robust evidence relying on assessments of single caregiver-child attachment patterns has corroborated this hypothesis. Nevertheless, most often children are raised by multiple caregivers, and they tend to form attachment bonds with more than one of them. In this paper, we briefly describe the conceptual and empirical roots underlying the notion of attachment network to multiple caregivers. We describe potential reasons for researchfocusing on a single caregiver (most often mothers, but recently also fathers) and the historical attempts to establish a more ecologically valid assessment of attachment to multiple caregivers. Finally, we describe a recently developed organizational framework that includes testable models on which future research may rely for assessing the predictive power of attachment networks to multiple caregivers on children’s developmental outcomes.
The current study examined the attachment development of 92 internationally adopted Chinese girls, focusing on the influence of type of pre-adoption care (institutional versus foster care) and sensitive adoptive parenting. Although the children were more often insecurely attached than non-adopted children 2 and 6 months after adoption (Times 1 and 2, N = 92), they had similar levels of secure base script knowledge (SBS knowledge) as a non-adopted comparison group at age 10 (Time 3, N = 87). Furthermore, concurrently observed sensitive parenting was positively associated with SBS knowledge. Finally, a significant interaction between type of pre-adoption care and early-childhood sensitive parenting indicated that the post-institutionalized children showed a stronger increase in security than the post-foster children when parents were more sensitive.
Résumé
But de l’étude
Cette étude a pour objectif d’évaluer le lien entre des indices de fonctionnement psychologique maternel et la qualité de l’attachement de l’enfant à sa mère, dans un échantillon clinique pédopsychiatrique.
Méthode
Vingt-neuf enfants (âgés entre 23 et 71 mois) consultant en service de pédopsychiatrie et leur mère ont participé à l’étude. L’attachement mère-enfant a été examiné avec la Situation Étrange ou la procédure de Séparation-Réunion, selon l’âge de l’enfant. Les symptomatologies dépressive et anxieuse des mères et le stress maternel ont été évalués à l’aide de questionnaires auto-administrés.
Résultats
La dépression maternelle est marginalement corrélée à l’attachement évitant alors que l’anxiété maternelle l’est de façon significative. Plus le niveau de stress ressenti par la mère dans l’exercice de son rôle parental est élevé, plus l’attachement de l’enfant est désorganisé et moins il tend à être sécure. Plus le niveau de stress maternel lié aux difficultés de l’enfant est élevé, plus l’attachement mère-enfant tend à être ambivalent.
Conclusion
Ces résultats soulignent l’intérêt de poursuivre la recherche sur les liens possibles entre des déterminants psychologiques maternels et l’attachement mère-enfant auprès de populations d’enfants consultant en pédopsychiatrie.
The quality of early caregiver–infant relationships has powerful implications for health trajectories across the lifespan, including associations with adult inflammation. However, because relatively few studies have examined this association during infancy, it remains unclear when this impact occurs and whether it is associated with longitudinal changes in salivary concentrations of inflammation across infancy. In 45 infants, we investigated whether the quality of infant‐caregiver attachment (secure vs. insecure) was associated not only with levels of salivary C‐reactive protein (sCRP) cross‐sectionally, but also with changes in sCRP across 6 months. Interestingly, while there were no cross‐sectional associations between infant‐caregiver attachment and inflammation at 12 months of age, infant‐caregiver attachment security predicted lower levels of sCRP 6 months later. In addition, attachment security predicted decreasing levels of sCRP from 12 months to 18 months of age. Implications for understanding the influence of the quality of early relationships on biological mechanisms related to disease are discussed.
This study examined the longitudinal associations between fathers’ observed parenting behaviors and father-infant attachment (n = 58 father-infant dyads). Fathers were observed playing with their infants at 9 months postpartum and were assessed for stimulating behaviors (i.e. physical and/or object stimulation), as well as their sensitivity and intrusiveness. When the infants were 12 to 18 months of age, fathers and infants participated together in the Strange Situation Procedure (SSP) to assess father-infant attachment security. Logistic regression analyses revealed that higher levels of paternal stimulation at 9 months postpartum were associated with greater odds of classification as a secure father-infant dyad. Additionally, fathers’ observed intrusiveness at 9 months postpartum moderated this association; greater paternal stimulation was associated with significantly greater odds of father-infant attachment security at low and average levels of paternal intrusiveness, but not at high levels of paternal intrusiveness. This study provides new insight into the paternal behaviors that may foster secure father-infant attachment.
Exposure to maltreatment during childhood (CM) can have deleterious effects throughout the life span of an individual. A parent's history of child maltreatment can also impact his or her own parenting behavior. Theoretically, parents who experienced maltreatment as children may have fewer resources to cope with the challenges of childrearing and may adopt more problematic parenting behaviors. However, empirical studies examining the association between CM and later parenting behavior have yielded mixed results. The aim of this study is to conduct a meta-analysis of studies that have examined the association between exposure to CM and the subsequent parenting outcomes of mothers of 0- to 6-year-old children. A secondary aim is to examine the potential impact of both conceptual and methodological moderators. A total of 32 studies (27 samples, 41 effect sizes, 17,932 participants) were retained for analysis. Results revealed that there is a small but statistically significant association between maternal exposure to CM and parenting behavior ( r = –.13, p < .05). Moderator analyses revealed that effect sizes were larger when parenting measures involved relationship-based or negative, potentially abusive behaviors, when samples had a greater number of boys compared to girls, and when studies were older versus more recent. Results are discussed as they relate to the intergenerational transmission of maltreatment and abuse.
Objective:
Observed associations between maternal prenatal stress and children's socioemotional development have varied widely in the literature. The objective of the current study was to provide a synthesis of studies examining maternal prenatal anxiety and depression and the socioemotional development of their children.
Method:
Eligible studies through to February 2018 were identified using a comprehensive search strategy. Included studies examined the association between maternal prenatal depression or anxiety and the future development of their children's socioemotional development (eg, difficult temperament, behavioral dysregulation) up to 18 years later. Two independent coders extracted all relevant data. Random-effects meta-analyses were used to derive mean effect sizes and test for potential moderators.
Results:
A total of 71 studies met full inclusion criteria for data analysis. The weighted average effect size for the association between prenatal stress and child socioemotional problems was as follows: odds ratio (OR) = 1.66 (95% CI = 1.54-1.79). Effect sizes were stronger for depression (OR = 1.79; 95% CI = 1.61-1.99) compared to anxiety (OR = 1.50; 95% CI = 1.36-1.64). Moderator analyses indicated that effect sizes were stronger when depression was more severe and when socio-demographic risk was heightened.
Conclusion:
Findings suggest that maternal prenatal stress is associated with offspring socioemotional development, with the effect size for prenatal depression being more robust than for anxiety. Mitigating stress and mental health difficulties in mothers during pregnancy may be an effective strategy for reducing offspring behavioral difficulties, especially in groups with social disadvantage and greater severity of mental health difficulties.
The Atypical Maternal Behavior Instrument for Assessment and Classification (AMBIANCE; Bronfman, Madigan, & Lyons-Ruth, 2009–2014; Bronfman, Parsons, & Lyons-Ruth, 1992–2004) is a widely used and well-validated measure for assessing disrupted forms of caregiver responsiveness within parent–child interactions. However, it requires evaluating approximately 150 behavioral items from videotape and extensive training to code, thus making its use impractical in most clinical contexts. Accordingly, the primary aim of the current study was to identify a reduced set of behavioral indicators most central to the AMBIANCE coding system using latent-trait item response theory (IRT) models. Observed mother–infant interaction data previously coded with the AMBIANCE was pooled from laboratories in both North America and Europe ( N = 343). Using 2-parameter logistic IRT models, a reduced set of 45 AMBIANCE items was identified. Preliminary convergent and discriminant validity was evaluated in relation to classifications of maternal disrupted communication assigned using the full set of AMBIANCE indicators, to infant attachment disorganization, and to maternal sensitivity. The results supported the construct validity of the refined item set, opening the way for development of a brief screening measure for disrupted maternal communication. IRT models in clinical scale refinement and their potential for bridging clinical and research objectives in developmental psychopathology are discussed.
Paternal depression and anxiety are important risk factors for a problematic parent–child relationship and subsequent child development. We explored the association between paternal history of depression and anxiety disorder and infant–father attachment security, taking into account the possible mediating roles of sensitivity and perceived family stress. In a sample of 94 infant–father dyads, a structured diagnostic interview and a questionnaire on family stress were administered during pregnancy. Paternal sensitivity was observed using the Ainsworth coding scales, and infant–father attachment was observed in the strange situation procedure during a lab visit at 14 months. Linear regression models were used to examine the association of father's lifetime depression or anxiety with the continuous scales for infant–father attachment security and disorganization. Father's history of depression or anxiety disorder was not significantly related to infant–father attachment security in the total sample. Interestingly, daughters of fathers with a history of depression or anxiety had higher scores on attachment security than daughters of fathers without this diagnosis. Perceived family stress and paternal sensitivity were not significant mediators. We discuss these unexpected findings, suggesting alternative mechanisms for how paternal vulnerability to depression or anxiety may be associated with the infant–father attachment relationship.
Highlights
• We examine the association between paternal history of depression and anxiety disorder and infant‐father attachment security.
• In 94 infant‐father dyads, a structured diagnostic interview was administered and infant‐father attachment was observed in the Strange Situation Procedure.
• Daughters of fathers with a psychiatric history had higher scores on attachment security. Mechanisms of paternal vulnerability are discussed.
A 2004 meta‐analysis reported good validity for the observer attachment Q‐sort (AQS), but poor validity for the parental self‐report version. Despite this, the self‐report AQS is still widely used, with researchers arguing that providing additional training can improve its validity. The aim of this study was to update the 2004 meta‐analysis. Two hundred forty‐five studies from 1987 to 2016 were included ( n = 32,426). Separate meta‐analyses were conducted to examine validity and reliability. The observer AQS showed moderate convergent validity with the Strange Situation Procedure ( r = .25; r = .39 for long observation periods) and good predictive validity in terms of associations with sensitivity ( r = .32). It showed a relatively weak association with infant temperament ( r = .21), suggesting some discriminant validity. The self‐report version showed comparable convergent validity with Strange Situation Procedure ( r = .18), but significantly weaker correlations with sensitivity ( r = .25) and stronger correlations with temperament ( r = .33). There was no evidence that providing additional training improved the validity of the self‐report version. This study corroborates the previous finding that the observer AQS is a valid measure of infant attachment, especially after long periods of observation. The self‐report version showed significantly weaker discriminant and predictive validity.
Highlights
The aim of the study was to update the 2004 meta‐analysis assessing the validity of the attachment Q‐Sort (AQS).
This study broadly replicated the findings of the previous meta-analysis, showing that the observer AQS is a valid measure of attachment.
Caution should be shown in using the self-report AQS due to its comparatively weaker predictive and discriminate validity.
This paper reports on three studies on the development and validation of the Parental Reflective Functioning Questionnaire (PRFQ), a brief, multidimensional self-report measure that assesses parental reflective functioning or mentalizing, that is, the capacity to treat the infant as a psychological agent. Study 1 investigated the factor structure, reliability, and relationships of the PRFQ with demographic features, symptomatic distress, attachment dimensions, and emotional availability in a socially diverse sample of 299 mothers of a child aged 0-3. In Study 2, the factorial invariance of the PRFQ in mothers and fathers was investigated in a sample of 153 first-time parents, and relationships with demographic features, symptomatic distress, attachment dimensions, and parenting stress were investigated. Study 3 investigated the relationship between the PRFQ and infant attachment classification as assessed with the Strange Situation Procedure (SSP) in a sample of 136 community mothers and their infants. Exploratory and confirmatory factor analyses suggested three theoretically consistent factors assessing pre-mentalizing modes, certainty about the mental states of the infant, and interest and curiosity in the mental states of the infant. These factors were generally related in theoretically expected ways to parental attachment dimensions, emotional availability, parenting stress, and infant attachment status in the SSP. Yet, at the same time, more research on the PRFQ is needed to further establish its reliability and validity. © 2017 Luyten et al.

Studies 1 and 2 investigated how maternal severe mental illness (SMI) related to mothers’ mind–mindedness (appropriate and nonattuned mind-related comments). Study 1 showed that mothers with SMI ( n = 50) scored lower than psychologically well mothers for both appropriate and nonattuned comments, whereas mothers with SMI in Study 2 ( n = 22) had elevated levels of nonattuned comments. Study 2 also tested the efficacy of a single-session video-feedback intervention to facilitate mind–mindedness in mothers with SMI. The intervention was associated with a decrease in nonattuned comments, such that on discharge, mothers did not differ from psychologically well controls. Study 3 assessed infant–mother attachment security in a small subset of intervention-group mothers from Study 2 ( n = 9) and a separate group of standard care mothers ( n = 30) at infant mean age 17.1 months ( SD = 2.1). Infants whose mothers completed the intervention were more likely to be securely attached and less likely to be classified as insecure–disorganized than those of mothers who received standard care. We conclude that a single session of video-feedback to facilitate mind–mindedness in mothers with SMI may have benefits for mother–infant interaction into the second year of life.
The purpose of the current study was to predict concurrent levels of problem behaviors from young children’s baseline cortisol and attachment classification, a proxy for the quality of caregiving experienced. In a sample of 58 children living at or below the federal poverty threshold, children’s baseline cortisol levels, attachment classification, and problem behaviors were assessed at 17 months of age. We hypothesized that an interaction between baseline cortisol and attachment classification would predict problem behaviors above and beyond any main effects of baseline cortisol and attachment. However, based on limited prior research, we did not predict whether or not this interaction would be more consistent with diathesis-stress or differential susceptibility models. Consistent with diathesis-stress theory, the results indicated no significant differences in problem behavior levels among children with high baseline cortisol. In contrast, children with low baseline cortisol had the highest level of problem behaviors in the context of a disorganized attachment relationship. However, in the context of a secure attachment relationship, children with low baseline cortisol looked no different, with respect to problem behavior levels, then children with high cortisol levels. These findings have substantive implications for the socioemotional development of children reared in poverty.
After decades of research on early attachment relationships, questions remain concerning whether the evidence supports claims made by attachment theory, in particular, that variation in early attachment predicts children's developmental adaptation or maladaptation, and that characteristics of children's temperament does not determine attachment. To evaluate these claims, we conducted meta-analyses on early attachment and children's social competence with peers, externalizing problems, internalizing symptoms, and temperament. In this article, we summarize our findings, which support attachment theory—though we note caveats. We also call for new measurement models, a focus on mediating and moderating mechanisms, and multisite replications.
This study, the first in Zambia using the Strange Situation Procedure (SSP) to observe attachment relationships and the “very first” observational study of infant–sibling attachment, examined patterns of infant–mother and infant–sibling attachment, and tested their association. We included siblings who were substantially involved in caregiving activities with their younger siblings. We hypothesized that infants would develop attachment relationships to both mothers and siblings; the majority of infants would be classified as securely attached to both caregivers, and infant–mother and infant–sibling attachment would be unrelated. The sample included 88 low-income families in Lusaka, Zambia (average of 3.5 children; SD = 1.5). The SSP distributions (infant–mother) were 59% secure, 24% avoidant and 17% resistant, and 46% secure, 20% avoidant, 5% resistant and 29% disorganized for three- and four-way classifications, respectively. The infant–sibling classifications were 42% secure, 23% avoidant and 35% resistant, and 35% secure, 23% avoidant, 9% resistant and 33% disorganized for three- and four-way classifications, respectively. Infant–mother and infant–sibling attachment relationships were not associated.
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.
This study examined whether child abuse history in teen mothers impacts offspring externalizing problems indirectly, through its influence on attachment and maternal hostility. In a longitudinal sample of 112 teen mother–child dyads, mothers reported on their own abuse experiences, attachment and maternal hostility were assessed via direct observations, and externalizing problems were measured using maternal reports. Compared with mothers with no abuse history, mothers with a history of sexual and physical abuse were more likely to have an insecurely attached infant, which predicted higher externalizing problems in preschool, which in turn predicted subsequent increases in externalizing problems in Grade 3. Furthermore, relative to the no abuse history group, mothers with a history of sexual and physical abuse showed more hostility toward their child at preschool, which in turn predicted elevated externalizing problems in Grade 3. Mothers’ history of either sexual or physical abuse alone did not have significant indirect effects on externalizing problems. Fostering secure attachment and reducing risk for maternal hostility might be important intervention goals for prevention programs involving at-risk mothers with abuse histories.
