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.

Multifactorial research must examine if disorganized attachment is specifically associated with either ODD- or ADHD-symptoms,and the mechanisms through which disorganization may become associated with externalizing problems. The present short-term longitudinal study therefore examined attachment representations, and several competences important for socio-emotional functioning, in relation to ODD- and ADHD-symptoms at T1 (N = 105, M age = 80 months) and T2 (N = 80, M age = 104 months). There was a main effect of disorganized attachment on ODD-symptoms at both time points but not on ADHD-symptoms. Disorganized children also showed lowered attention to facial expressions, a diminished ability to discriminate facial expressions, and elevated emotional reactivity. Emotional reactivity mediated the link between disorganization and ODD-symptoms at T1, but not at T2. The findings support disorganized attachment as a risk-factor for ODD-symptoms rather than ADHD-symptoms, and suggest that disorganization may become associated with ODD-symptoms through broad effects on multiple competences.

Scholarly discussion suggests prevalent, overconfident use of attachment classifications in child protection (CP) investigations but no systematic research has examined actual prevalence, the methods used to derive such classifications, or their interpretations. We aimed to cover this gap using survey data from a nationally representative sample of Swedish CP workers (N = 191). Three key findings emerged. First, the vast majority formed an opinion about young children’s attachment quality in all or most investigations. Second, most did not employ systematic assessments, and none employed well-validated attachment methods. Third, there was overconfidence in the perceived implications of attachment classifications. For example, many believed that insecure attachment is a valid indicator of insufficient care. Our findings illustrate a wide researcher-practitioner gap. This gap is presumably due to inherent difficulties translating group-based research to the level of the individual, poor dissemination of attachment theory and research, and infrastructural pressures adversely influencing the quality of CP investigations.

Research has suggested highly elevated levels of interpersonal trauma (IPT) among parents with intellectual disabilities (ID), and that such experiences may contribute to the caregiving and child developmental problems often seen in this population. Conflicting results have however been reported, and there is no systematic review on this matter. This study therefore systematically reviewed the empirical evidence concerning (a) prevalence of IPT among parents with ID, and links with (b) caregiving-relevant and (c) child developmental outcomes, in accordance with the PRISMA 2020 guidelines. Searches were conducted in MEDLINE, CINAHL, PsycINFO, and PTSDpubs. Peer-reviewed empirical articles reporting exposure to any form of systematically assessed IPT (unspecified IPT, physical, sexual, and emotional abuse, neglect, prolonged childhood separations from caregivers, witnessing abuse in the family) among parents with ID were included, yielding a final selection of 20 studies. Findings consistently indicated markedly elevated levels of IPT among parents with ID, with a majority (>50%) having experienced some form of IPT. Estimates for both unspecified and specific forms were typically higher than corresponding estimates in other groups at elevated risk, and than meta-analytical general population estimates in comparable countries. Findings regarding caregiving-relevant outcomes were mixed but indicated links with adverse outcomes, particularly regarding parental mental health. Reports pertaining to child developmental outcomes were scant and inconsistent. We highlight important limitations in the extant literature and provide directions for future research and clinical practice.

The development of children's ability to identify facial emotional expressions has long been suggested to be experience dependent, with parental caregiving as an important influencing factor. This study attempts to further this knowledge by examining disorganization of the attachment system as a potential psychological mechanism behind aberrant caregiving experiences and deviations in the ability to identify facial emotional expressions. Typically developing children (N = 105, 49.5% boys) aged 6–7 years (M = 6 years 8 months, SD = 1.8 months) completed an attachment representation task and an emotion identification task, and parents rated children's negative emotionality. The results showed a generally diminished ability in disorganized children to identify facial emotional expressions, but no response biases. Disorganized attachment was also related to higher levels of negative emotionality, but discrimination of emotional expressions did not moderate or mediate this relation. Our novel findings relate disorganized attachment to deviations in emotion identification, and therefore suggest that disorganization of the attachment system may constitute a psychological mechanism linking aberrant caregiving experiences to deviations in children's ability to identify facial emotional expressions. Our findings further suggest that deviations in emotion identification in disorganized children, in the absence of maltreatment, may manifest in a generally diminished ability to identify emotional expressions, rather than in specific response biases.
