Attachment theory, with its core concepts, perspectives, and insights developed over the past five decades, is influential for professionals working with young children. However, practitioners face challenges translating attachment theory and research into practical applications. This manifests in attachment myths, theoretical misinterpretations, and inconsistency of application. This state‐of‐the‐art review is authored by 47 attachment researchers and practitioners and examines key insights from attachment theory to facilitate attachment‐aware practice for professionals working with children and their caregivers. Following the ongoing debate on practical relevance in attachment theory, we present both ‘strict’ and ‘expansive’ translational perspectives on applications for addressing preventative or clinical attachment concerns. We first review core attachment propositions, based on replicated research of attachment and caregiving. We next address common misconceptions that hinder adequate practical applications. We present measures of attachment and sensitive parenting that might be helpful for practitioners. We also review evidence‐based and promising attachment interventions, discussing core components of (preventative) support for parents or caregivers and the children in their care. We emphasize that attachment theory's clinical value lies not in assigning attachment classifications, but rather in understanding crucial insights into caregiving and early socioemotional development (e.g., secure base phenomena; the value of safe, stable, and shared good‐enough care), developed in attachment research over the past 50 years, that may inform policy and clinical reasoning and areas for prevention and intervention.

Children's theory of mind (ToM) and emotion regulation (ER) have been associated with various parental factors. This study examined associations between ToM, ER, and dimensions of parental reflective functioning (RF) in children aged 7 to 12 years. A total of 95 children (M = 8.85 years, 51 girls, and 44 boys) and their mothers took part in the study. Children completed two higher‐order ToM tasks and mothers rated their own RF and children's ToM and ER. Analyses revealed unique effects of parental prementalizing modes (PM) on both task‐measured and parent‐reported ToM as well as on children's socially‐appropriate ER skills and their lability/negativity. Moreover, parents’ interest and curiosity about their children's mental states (IC) was uniquely associated with parent‐reported ToM and ER. The study also revealed bidirectional mediation effects, with ToM mediating the relationship between ER and both PM and IC, and ER mediating the relationship between ToM and both PM and IC.

How parents cope with stress as a couple (i.e., dyadic coping [DC]) is related to mental health problems in children. But little is known about DC within first-time parents and child mental health problems in early childhood. This study investigated subgroups in DC trajectories across the transition to parenthood (TTP) and examined subgroup differences in child mental health problems. Mothers' and fathers' self-report of positive and negative DC (n = 288 couples) at seven points of measurement (27th, 32nd week of pregnancy, 2nd, 14th, 40th week postpartum, 3- and 4-year postpartum) and children's emotional and behavioral problems from parent report (4-year postpartum) were used. Latent class growth analyses revealed that over half of the couples experienced a moderate decline in positive DC across the TTP (58%), whereas only fathers reported a decline among the remaining couples (42%). Fathers with a partner who maintained their level of positive DC reported more child emotional and behavioral problems than fathers whose partners' DC also decreased. Results for negative DC indicated two subgroups in which one partner maintained their initial level of negative DC (stable fathers: 10%, stable mothers: 23%), while the other increased. In most couples, both parents increased their negative DC (67%). Fathers reported more child emotional and behavioral problems if their negative DC increased across the TTP than if their negative DC remained stable regardless of the negative DC of their partner. The existence of different DC trajectory patterns needs to be considered in further research as well as prevention. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Attachment security and dependency play a decisive role for children’s mental health. From a family systems perspective, reciprocal effects of dyadic attachment to each parent within the same family on child symptomatology may well offer additional insights in developmental processes as parents and children influence each other consistently. This study examined the influence of child-mother as well as child–father attachment security and dependency on maternal, paternal, and observed ratings of children’s emotional and behavioral problems. A total of 124 families with preschool children participated in this study. Attachment security, dependency, and symptomatology of the children were independently observed during home visits. Furthermore, mothers and fathers rated child symptoms. Results revealed promotive effects of attachment security to both parents on observed child symptoms. Furthermore, we found a significant actor effect of child-mother attachment security, as well as a significant partner effect of child–father dependency on maternal ratings of child symptomatology. Attachment security to both parents is promotive for child mental health. The family systems perspective clarifies the meaning of child–father relationships for maternal perception of the own child.

Most studies examining gene-environment effects on self-regulation focus on outcomes early childhood or adulthood. However, only a few studies investigate longitudinal effects during middle childhood and adolescence and compare two domains of early caregiving. In a longitudinal follow-up with a sample of N = 87, we studied the effects of differences in the DRD4 tandem repeat polymorphisms and two domains of early maternal caregiving quality on children’s personality development using Block’s California Child Q-Set (CCQ) at age six and age 12 and on problem behavior at ages six and seven. Early maternal regulation quality predicted later ego-resiliency and aggressiveness. In addition, significant gene-environment interactions revealed that children with the 7+ DRD4 tandem repeat polymorphism and poor maternal regulation quality in infancy showed lower scores in ego-resiliency and higher scores in ego-undercontrol and CCQ aggressiveness. In contrast, children who had experienced effective maternal regulation in infancy showed a comparable level in personality traits and problem behavior as the DRD4 7- group independent of the levels of maternal regulatory behavior. Similarly, longitudinal caregiving × DRD4 interactions were found for behavior problems in middle childhood, especially for oppositional-aggression, inattentive-hyperactivity, and social competence. Early caregiving effects were only found for maternal regulation quality, but not for maternal responsiveness. Effective early maternal regulation in infancy can moderate the negative effect of DRD4 7+ on children’s self-regulation in middle childhood and adolescence. However, maternal responsiveness has no comparable effects. It seems relevant to consider several dimensions of early caregiving and to also measure the environment in more detail in gene-environment studies.

Fathering and mothering have changed in many ways within the last decades. Earlier studies showed a clear hierarchy in infant attachment figures with a preference for mothers. This study examined whether infants in the 21st century still prefer mothers over fathers in their expression of attachment behaviors, whether differences in parental involvement still exist, and whether this will result in differences in attachment security to mother and father. A total of 50 German families with infants between 10 and 19 months were observed in an experimental setting and during home visits. Parents reported on their involvement. The results revealed a clear hierarchy with regard to the duration of attachment behaviors directed towards mothers, followed by fathers and strangers. Mothers reported to be more involved in child care on weekdays compared to fathers. Involvement was not associated with attachment variables. Attachment security to mother and father was positively related and did not differ significantly. Infants in the 21st century in a Western country still prefer mothers over fathers in their expression of attachment behaviors. Mothers were more involved in child care than fathers. However, these differences did not result in differences in attachment security to mother and father.

Family risks are known to be detrimental to children's attachment development. This study investigated whether parental sensitivity plays different roles in early attachment development in the context of risk: Sensitivity was hypothesized to mediate risk effects on attachment, as well as a moderator that shapes the relation between risk and attachment. Multiple family risks, parental sensitivity (defined as responsivity and supportive presence), and children's attachment security of 197 infants and toddlers (M_age = 15.25 months) and their caregivers were assessed in a prospective study with a cohort‐sequential‐design in Germany. Caregivers' sensitivity served as a mediator of risk effects on attachment as well as a moderator that buffers adverse consequences of risk. Early sensitivity might be relevant in setting the stage for attachment development supporting resilience.

Growing up in high-risk environments is detrimental to children’s development of attachment security. Parenting behavior is hypothesized to be the mechanism through which risks exert their influence. However, risk influences can vary between individuals by gender. Aim of this study was to explore specific pathways of family risk on early attachment security and additionally examine the transmission via parenting behavior. The sample consisted of 197 children and their primary caregivers. Children’s age ranged between 10 and 21 months (M = 15.25, SD = 3.59). Data assessment included 21 distal and proximal family risk factors, children’s attachment security, and parental responsivity and supportive presence. Whereas distal risk factors had an adverse effect only on girls’ attachment security, proximal risks negatively affected only boys’ attachment security. Additionally, patterns of risk factors occurring in our sample were analyzed using an exploratory principal component analysis. Regardless of the child’s gender, a low socio-economic status was negatively related to attachment security of all children. Migration and crowding and a high emotional load of the primary caregiver both negatively predicted girls’ but not boys’ attachment security. However, the attachment security of boys was affected by a negative family climate. Most of the adverse risk effects on attachment security were mediated by parental responsivity and supportive presence so that the transmission of risk occurs through parenting behavior. Results revealed a different susceptibility of family risks for girls and boys. The consideration of a gender-sensitive approach in developmental psychopathology and interventions of developmental child welfare services is recommended.

Fast and accurate screening for mental health problems in early childhood is a prerequisite for effective early intervention. The Early Childhood Screening Assessment (ECSA) is a valid and standardized screening tool for young children. The aims of the current study were to examine the psychometric properties, the factorial structure, and validity evidence for test score interpretation of the German version of the ECSA. Results of a confirmatory factor analysis support a two-factor solution differentiating externalizing and internalizing problems in early childhood. Concurrent validity was demonstrated by positive associations with the Child Behavior Checklist (CBCL). Accuracy of identifying children at risk in comparison to CBCL was good with appropriate sensitivity and specificity. Moreover, ECSA problem scores showed specific associations with low ego-resiliency and field-independence scores and high ego-undercontrol, aggression, and anxiety scores. ECSA caregiver depression scores were associated with children’s ECSA problem scores. The German version of the ECSA is a short and accurate screening tool for mental health problems in early childhood.
