Article
Contrary to the substantial amount of research on infant, preschool, adolescent, and adult attachment, middle childhood has long been neglected by the international attachment research community. In the past two decades, however, there has been a steep increase in research focusing on middle childhood attachment. This article provides an overview o...
Article
Full-text available
Meta-analyses consistently demonstrate that Cognitive Behaviour Therapy (CBT) provides effective evidence-based treatment for children and adolescents with emotional and behaviour problems. Also consistent across meta-analyses is the observation that CBT treatment effects are often medium in size. This observation has instigated a search for factor...
Article
Full-text available
Attachment is an inborn behavioral system that is biologically driven and essential for survival. During child development, individual differences in (in)secure attachment emerge. The development of different attachment behaviors has been traditionally explained as a process during which experiences with (lack of) responsive and supportive care are...
Article
Full-text available
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 atta...
Article
The current study explored dynamics of secure state attachment expectations in everyday life in middle childhood, specifically state attachment carry-over and reactivity to experiences of caregiver support in the context of stress. In two independent samples (one community sample, N = 123; one adoption sample, N = 69), children (8–12 years) daily r...

Full-text available
To better understand the attachment-depression link among undergraduate students in Iran, the current study examined reflective functioning (RF) and loneliness as variables explaining the relationship between attachment avoidance and anxiety and depressive symptoms. Participants were 423 undergraduate female students in Tehran, Iran, aged between 1...
Article
Full-text available
Part of the appeal of attachment language is that it feels near to our everyday experience, as terms like 'attachment', 'security' or 'disorganisation' feel readily recognisable. Yet, not one of these terms is used by academic attachment researchers in line with ordinary language. This has hindered the evidence-based use of attachment in practice,...
Article
Full-text available
Attachment theory proposes that the activation of the attachment system enacts emotion regulation (ER) to maintain security or cope with insecurity. However, the effects of ER on attachment states and their bidirectional influences remain poorly understood. In this ecological momentary assessment study, we examined the dynamics between attachment a...
Article
Full-text available
Brooding rumination is a maladaptive form of emotion regulation and confers a risk for psychopathology. Insecure attachment and low cognitive self-regulation are important antecedents of brooding. Yet, little is known about the developmental interplay between these two systems. Thus, we tested how children's attachment and cognitive self-regulation...
Article
Recent studies showed that attachment security can change within persons, suggesting that there might be an interplay between a rather stable (trait) and rather variable (state) part of attachment. The study’s first aim was to investigate whether attachment priming could influence the level of state attachment. The second aim was to explore possibl...
Article
Full-text available
The short form of the Experiences in Close Relationships Scale-Revised Child version (ECR-RC) is a promising self-report measure of anxious and avoidant attachment in Western adolescents, yet little is known about its psychometric properties across cultures. More importantly, little is known about attachment styles across cultures, child gender and...
Article
Background A digital micro-intervention offering attachment psychoeducational videos was explored regarding its feasibility in parents of children with severe disabilities. Method: A mixed-methods study (including daily diaries and one-time questionnaires) with 16 parents (75.0% female) of children with severe disabilities (up to 10 years of age) w...
Article
Anxiety and depressive symptoms are common, comorbid, and consequential for adolescents. Attachment theory suggests that styles of relationships with parents, developed from patterns of interactions over time, contribute to risk for these internalizing symptoms. This may be especially relevant for high-risk, clinically severe adolescents. However,...
Article
Parents of children with severe disabilities have differing attachment-related support needs. An online vignette study with 25 experts, working in academia and/or clinical practice, was conducted to reflect upon the task of matching intervention components to families, based on their attachment strengths and needs. In two online rounds, the experts...
Article
Full-text available
Throughout development, the conditions that elicit children’s support seeking behaviour change hand in hand with maturation and changing developmental tasks. Little is known about the situations in which adolescents need support or about which parental behaviours elicit adolescents’ sense of being supported. In the current study, adolescents living...
Article
Full-text available
Behavioral parent training is an evidence-based intervention for children with attention-deficit/hyperactivity disorder (ADHD), but knowledge on the differential effects of behavioral techniques for specific subgroups of children is very limited. Attachment representations of children with ADHD may affect how receptive children are to changes in pa...
Article
Young adolescents are hypothesized to differ in their environmental sensitivity, at both phenotypic (i.e., Sensory Processing Sensitivity [SPS]) and physiological (i.e., biological stress response) level. This is the first study that investigated whether individual differences in environmental sensitivity at physiological level could be predicted b...
Article
Full-text available
There has been an increase in peer violence in Vietnam. Although normative beliefs approving aggression have been considered an important factor in the development of peer violence in Western countries, few studies examine the factor in Vietnamese context. This limitation may be due to the lack of a validated scale used to evaluate the factor. The...
Article
Full-text available
Displaying selective attachment behaviours is an important developmental milestone for children with severe or profound intellectual disabilities (SPID). In the current study, between-child differences in their selective emotional responses to comfort provided by parents versus strangers were observed. We explored links between these differences an...
Article
Full-text available
Attention-Deficit/Hyperactivity Disorder (ADHD) in children is associated with several adverse family characteristics, such as higher parenting stress, more conflicted parent-child relationships , lower parental competence, and higher levels of parental psychopathology. Hence, children with ADHD more often grow up under suboptimal circumstances, wh...
Article
Full-text available
Research suggests that inter-individual differences in the degree of state attachment variability are related to differences in trait attachment and psychological problems between children. In this study, we tested whether such associations are also relevant at a within-person level, and if so, whether intra-individual fluctuations in the degree of...
Article
We examined the prototype v. revisionist models of attachment stability with a five‐wave, 6‐year, longitudinal study of attachment security from middle childhood to adolescence in a White Western European sample (N = 157; Wave 1 Mage = 10.91, SD = 0.87; 52% female). Attachment was assessed using both questionnaire (Experiences in Close Relationship...

Full-text available
Co-rumination has consistently been shown to be maladaptive in the context of emotional well-being. However, not much is known about factors that predict one’s tendency to co-ruminate. The current study investigated temperament, attachment, and gender as predictors of co-rumination trajectories in a sample of 1549 early and middle adolescents from...
Article
Full-text available
Although widely accepted, attachment theory’s hypothesis that insecure attachment is associated with the development of depressive symptoms through emotion regulation strategies has never been longitudinally tested in adolescence. Additionally, previous research only focused on strategies for regulating negative affect, whereas strategies for regul...
Method
The Middle Childhood Attachment Micro-Observation System (MCAM) has been developed to micro-code attachment-related behaviors of a parent and a child (aged 8 - 12). The current version has been used by Bodner et al. (2019). In this study, a mother and child were asked to solve an unsolvable puzzle. After an initial stress induction to the child, th...
Article
Background The feasibility and acceptability was explored of the newly-constructed Attachment Strengths and Needs Interview for parents of children with severe or profound intellectual disabilities. Method A partially mixed methods approach (with focus on the quantitative data) was used to clarify parents’ and professionals’ viewpoints regarding t...

Full-text available
It is becoming clear that the COVID-19 pandemic has had a devastating psychological impact on Vietnamese society, but little is known about its impact on Vietnamese students. In the current study, we evaluated whether anxiety of contracting COVID-19 is related to students' learning burnout. Specifically, we tested two months into the pandemic wheth...
Article
Background The study examined how teachers and children with emotional and behavioral disturbances engage in dialogues about children’s emotional experiences. Dialogues about emotions are an important strategy for teachers to co-regulate children’s emotions but have remained understudied. Aims This study aimed to explore whether the Autobiographic...
Article
The current study investigated whether variations at the level of the cortisol stress response moderate the association between parental support and attachment development. To test this hypothesis, we conducted a one-year longitudinal study with two waves in which 101 children (56% girls, Mage = 11.15, SDage = 0.70) participated. Attachment anxiety...

Full-text available
There is a surge of research on the link between attachment and the selective processing of pictorial stimuli. However, the pictures that are often presented in the experimental paradigms have not been specifically related to attachment and moreover, have not been validated and unified based on different dimensions of emotion. Therefore, preparing...
Article
In this study, we sought to expand on what is currently known regarding autonomic nervous system (ANS) reactivity in middle childhood as a function of attachment. ANS activity includes multiple indices - respiratory sinus arrhythmia (RSA) is an index of parasympathetic nervous system activation (PNS) and electrodermal activity (EDA) is an index of...

Theory and research both point at epigenetic processes affecting both parenting behavior and child functioning. However, little is known about the convergence of mother and child’s epigenetic patterns in families. Therefore, the current study investigated epigenetic covariance in mother–child dyads’ methylation levels regarding four stress-regulati...
Article
Full-text available
Research on the association between childhood attachment and depressive symptoms has primarily focused on the role of risk factors. This resulted in a lack of research on the role of potential resilience factors. In the current study, we suggest that middle childhood secure attachment is linked to adolescents’ trait gratitude, which is linked to th...

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...
Article
Many theories have been put forward on how people become synchronized or co-regulate each other in daily interactions. These theories are often tested by observing a dyad and coding the presence of multiple target behaviours in small time intervals. The sequencing and co-occurrence of the partners' behaviours across time are then quantified by mean...

The breadth of children's attentional field around their mother determines whether securely or insecurely attached children are at risk to develop depressive symptoms when confronted with distress in adolescence. To test this effect longitudinally, we measured children's (M age = 10.93; N = 109) baseline attentional breadth around their mother, att...

Research has indicated that a strictly dimensional or parental style approach does not capture the full complexity of parenting. To better understand this complexity, the current study combined these two approaches using a novel statistical technique, i.e., subspace K-means clustering. Four objectives were addressed. First, the study tried to ident...

Trust in parental support and subsequent support seeking behavior, a hallmark of secure attachment, result from experiences with sensitive parents during distress. However, the underlying developmental mechanism remains unclear. We tested the hypothesis that trust is the result of an expectancy-learning process condtional upon contingency (the prob...
Article
Full-text available
Social anxiety is characterised by a bias to recall negative social autobiographical memories as well as anxious expectations about future social interactions. Neuroscientific research shows that a shared neural network underlies both temporal directions of autobiographical recall and future self-projections. Inspired by these findings, the current...

Full-text available
Micro-level family interaction processes are considered to be the engines of child development as well as indicators of (mal)adaptation. Studying these interaction patterns in moment-to-moment exchanges between parents and their children, seems thus to be the next step in order to advance theory and, in the long run, diagnostic processes and interv...

Article
We investigated (1) whether 10-year-old internationally adopted Chinese girls who, on average, showed below-average intellectual functioning two and six months after adoption (Times 1–2, N = 92), showed catch-up in intellectual functioning, school achievement, and executive functioning nine years later (Time 3, N = 87). We tested (2) effects of typ...
Article
Full-text available
Attachment theory states that children learn to trust in their parent’s availability and support if they repeatedly experience that their parents respond sensitively to their needs during distress. Attachment is thus developed and shaped by day-to-day interactions, while at the same time, each interaction is a momentary expression of the attachment...
Article
Child welfare systems (CWSs) worldwide show increased interest in adopting empirically informed clinical strategies to increase treatment effectiveness. Many empirically supported treatments (ESTs) exist, but little is known about EST implementation barriers and facilitators in CWS. This study explored CWS providers' experiences of implementing att...
Article
Background and objectives. Research on the social effects of intranasal oxytocin in children is scarce. Oxytocin has been proposed to have clearer beneficial effects when added to social learning paradigms. The current study tested this proposition in middle childhood by assessing effects of cognitive bias modification (CBM) training and oxytocin o...
