Taxometric Analysis of Secure Base Script Knowledge in Middle Childhood Reveals Categorical Latent Structure

Evidence of a developmental shift in the nature of attachment representations: a longitudinal taxometric investigation of secure base script knowledge from middle childhood into adolescence

Prior research suggests that secure base script knowledge is categorically distributed in middle childhood but becomes dimensionally distributed from late adolescence onward, potentially indicating a developmental shift in the nature of secure base script knowledge. Secure base script knowledge may initially be sparse, giving rise to categorical individual differences, while increased relational experiences later in development might contribute to more elaborated secure base script knowledge and dimensional individual differences. However, the cross-sectional nature of prior research limits inferences about developmental changes. To address this, we conducted a three-year, three-wave longitudinal study with a Western European sample transitioning from middle childhood to adolescence. At Wave 1 (n = 599, Mage = 10.30), secure base script knowledge was categorically distributed. By Wave 2 (n = 435, Mage = 11.30), distribution was ambiguous, and by Wave 3 (n = 370, Mage = 12.09), individual differences were dimensional. These results suggest a developmental shift in secure base script knowledge during the transition into adolescence.

Secure base and mental health in children: a narrative review

Background and Objective

Childhood is a crucial period for the formation of an individual's attachment type. Previous studies focused more on how to directly intervene in children's mental health problems such as depression, and less on how to improve children's mental health from the perspective of attachment relationship. Secure base, as one of the core concepts of attachment theory, plays an important role in the whole process of children's psychological development. In this article, we review the concept of the secure base, describe current clinical practice and suggest future directions.

Methods

A literature search was performed within electronic databases such as Web of Science, PubMed, and CNKI. Chinese and English articles focusing on the secure base and attachment relationship among children were retrieved. Their publication dates were set from the inception of the database to August 6, 2024.

Key Content and Findings

While the secure base significantly impacts early childhood, a safe base may also be established through group and teacher-student relationships to activate individual secure attachment schemas. Most prior studies concentrated on the mother-child bond, with limited exploration of the father's role in the family dynamic. Furthermore, children's secure attachment development is not only influenced by parents' secure base script knowledge (SBSK) but also by intergenerational transmission. The underlying structure of secure base scripting knowledge plays a distinct role in middle childhood mental health.

Conclusions

The mechanism by which family structure, the functional division of family roles, and the potential structure of safe-base script knowledge influence children's secure attachment development at various stages warrants further elucidation, including investigating cross-gender and cross-cultural stability. To facilitate the development of children's secure attachment pathways, it is essential to consider different attachment styles within parents and diverse family structures (including those in lesbian, gay, bisexual). From a clinical psychotherapy perspective, this review offered novel insights and practical guidance on how the secure base mechanism impacts children's mental health, with the overarching goal of mitigating the risk of mental health problems.

Depression in middle childhood: secure base script as a cognitive diathesis in the relationship between daily stress and depressive symptoms

A better understanding of protective factors against childhood depression may allow for the mitigation of severe and chronic symptoms and the timely implementation of intervention strategies. This study investigated the protective effect of having a secure base script on depressive symptoms when children face daily stressors. To test this hypothesis, moderation analyses were performed in a cross-sectional study with 378 children (48.5% boys, 51.5%) aged 8-12 years (M = 10.20; SD = 0.57). The results provided some support for the moderation effect when secure base script knowledge was investigated as a categorical variable in middle childhood. However, the results did not support the moderation effect when investigating secure base script as a continuous variable. Therefore, future investigations may need to address whether a categorical approach could better elucidate the protective role of secure base script knowledge in childhood depression.

Cumulative family stress and externalizing problems: Secure base script knowledge as a protective factor

The current study examined whether secure base script knowledge can buffer against higher concurrent externalizing problems and against relative increases in externalizing problems associated with cumulative family stress. We conducted a one-year longitudinal study with two waves between 2017 and 2019 in which 272 Dutch-speaking Western European children from Flanders (47.8% boys, M age = 10.20 , SD age = 0.60 $$ {M}_{\mathrm{age}}=10.20,{SD}_{\mathrm{age}}=0.60 $$ ) participated. Secure base script knowledge was associated with lower concurrent externalizing problems (f²  = 0.03). High levels of secure base script knowledge also buffered against relative increases in externalizing problems associated with cumulative family risk (f²  = 0.02). These findings suggest that secure base script knowledge can mitigate the negative effects of a stressful family environment on externalizing problems.

Disorganized attachment behaviors in infancy as predictors of brain morphology and peer rejection in late childhood

Studies show robust links between disorganized attachment in infancy and socioemotional maladjustment in childhood. Little is known, however, about the links between disorganized attachment and brain development, and whether attachment-related differences in brain morphology translate into meaningful variations in child socioemotional functioning. This study examined the links between infants' disorganized attachment behaviors toward their mothers, whole-brain regional grey matter volume and thickness, and peer rejection in late childhood. Thirty-three children and their mothers took part in this study. The Strange Situation Procedure was used to assess mother-infant attachment when infants were 18 months old. Magnetic resonance imaging was performed when they were 10 years old to assess cortical thickness and grey matter volumes. Children and teachers reported on peer rejection 1 year later, as an indicator of socioemotional maladjustment. Results indicated that disorganized attachment was not associated with grey matter volumes. However, children who exhibited more disorganized attachment behaviors in infancy had significantly thicker cortices in bilateral middle and superior frontal gyri, and extending to the inferior frontal gyrus, as well as the orbitofrontal and insular cortices in the right hemisphere in late childhood. Moreover, children with thicker cortices in these regions experienced greater peer rejection, as rated by themselves and their teachers. Although preliminary, these results are the first to indicate that disorganized attachment may play a role in cortical thickness development and that changes in cortical thickness are associated with differences in child socioemotional functioning.

Attachment Stories in Middle Childhood: Reliability and Validity of Clinical and Nonclinical Children's Narratives in a Structured Setting

Middle childhood is one of the most understudied periods of development and lacks a gold standard for measuring attachment representations. We investigated the reliability and validity of a Dutch version of the Story-Stem Battery coded using the Little Piggy Narrative (LPN) Coding System in a clinical (N = 162) and a nonclinical group (N = 98) of 4–10-year-old children. Their attachment stories were furthermore coded using the coherence scale. Factor analyses showed that the items of the LPN system formed four attachment scales and a separate scale reflecting distress/anxiety, with sufficient internal consistency for the scales and high interrater reliability (n = 20). Furthermore, we studied construct and discriminatory validity. The attachment scores correlated with coherence and child behavioral problems in the expected direction. Results showed age and gender differences, indicating that separate norm groups are necessary. In particular, disorganized attachment, coherence and distress/anxiety differ between clinical and nonclinical children across age and gender. Results for the other three organized attachment scales were more complex. For instance, older boys from the nonclinical group had higher scores on secure attachment than their clinical peers, while girls from the clinical and nonclinical groups did not differ, even though girls in the nonclinical group had higher secure attachment scores than boys. Results are discussed in light of attachment theory and developmental pathways in middle childhood, as well as their clinical implications.

A Learning Theory Approach to Attachment Theory: Exploring Clinical Applications

Although clinicians typically acknowledge the importance of insecure attachment as one factor that can contribute to children's psychopathology, translating attachment theory into clinical practice has proved a challenge. By specifying some of the mechanisms through which the child's attachment develops and changes, learning theory can enhance attachment based approaches to therapy. Specifically, interventions building on operant (parent management training) and classical (exposure therapy) learning can be used to stimulate new learning that increases the child's security and confidence in the parent's availability and responsiveness. To explore the clinical application and utility of a Learning Theory of Attachment (LTA), we focus on two attachment-focused interventions: Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD) and Middle Childhood Attachment-based Family Therapy (MCAT). VIPP-SD is an evidence-based parent management training designed to promote sensitive parenting and secure attachment in early childhood. MCAT is a recently developed intervention that uses exposure to stimulate secure attachment in middle childhood. LTA sheds light on the mechanisms set in train by VIPP-SD and MCAT facilitating the induction of professionals in clinical applications.

Current Perspectives on the Management of Reactive Attachment Disorder in Early Education

Children with Reactive Attachment Disorder (RAD) have special educational needs that are challenging for teachers in early education. In the current contribution, we will discuss a large body of research suggesting that stimulating these children's attachment development is feasible for teachers and potentially a successful strategy to ensure that these children thrive better in the classroom and socially. The current overview discusses research and theory on RAD and RAD treatment and results in the formulation of specific recommendations for the successful management of children with RAD in the classroom.

Reactive attachment disorder symptoms and prosocial behavior in middle childhood: the role of Secure Base Script knowledge

BACKGROUND

Children with attachment disorder show prosocial behavior problems. Children with a reactive attachment disorder show inhibited and emotionally withdrawn behavior. Consequently, these children typically display prosocial behavior problems. However, the underlying mechanism between reactive attachment disorder and prosocial behavior problems is still unclear and findings in literature are mixed.

METHODS

The current study investigated the role of children's attachment representations in this association. Attachment representations reflect knowledge about a cognitive script regarding the attachment figure as a source for support (Secure Base Script). We tested whether secure base script knowledge 1) mediates or 2) moderates the link between reactive attachment disorder and prosocial behavior problems in 83 children (6-11 years; 83.1% boys) recruited from special education schools for children with behavioral problems. Children completed a pictorial Secure Base Script Test. Their reactive attachment disorder symptoms were assessed during an interview with the primary caregivers. Primary caregivers and teachers filled out a prosocial behavior questionnaire about the child.

RESULTS

Results did not support the mediation hypothesis, but evidence for the moderation hypothesis was found. Secure base script knowledge attenuated the negative association between attachment disorder symptoms and prosocial behavior.

CONCLUSIONS

These findings contribute to the discussion about the link between attachment representations and attachment disorders.

Dimensions over categories: a meta-analysis of taxometric research

Taxometric procedures have been used extensively to investigate whether individual differences in personality and psychopathology are latently dimensional or categorical ('taxonic'). We report the first meta-analysis of taxometric research, examining 317 findings drawn from 183 articles that employed an index of the comparative fit of observed data to dimensional and taxonic data simulations. Findings supporting dimensional models outnumbered those supporting taxonic models five to one. There were systematic differences among 17 construct domains in support for the two models, but psychopathology was no more likely to generate taxonic findings than normal variation (i.e. individual differences in personality, response styles, gender, and sexuality). No content domain showed aggregate support for the taxonic model. Six variables - alcohol use disorder, intermittent explosive disorder, problem gambling, autism, suicide risk, and pedophilia - emerged as the most plausible taxon candidates based on a preponderance of independently replicated findings. We also compared the 317 meta-analyzed findings to 185 additional taxometric findings from 96 articles that did not employ the comparative fit index. Studies that used the index were 4.88 times more likely to generate dimensional findings than those that did not after controlling for construct domain, implying that many taxonic findings obtained before the popularization of simulation-based techniques are spurious. The meta-analytic findings support the conclusion that the great majority of psychological differences between people are latently continuous, and that psychopathology is no exception.
