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.

This paper reports on findings from a sample of 63 children at 6 years old, and 49 children at 11 years old, all from the same cohort who had been observed with mother in the Strange Situation at 1-year-old. At 6 and 11 years, the children responded to the task of providing verbal labels for line-drawn (caricatures of) emotion faces. The faces comprised the six basic emotions identified as such by Darwin (sadness, happiness, anger, fear, surprise, and disgust) as well as a neutral face and two more complex (blended) emotions (mischievousness and disappointment). Infant–mother attachment was linked significantly with children's emotion judgments 5 years and, to a lesser extent, 10 years after the Strange Situation assessment. Results are discussed in terms of the long-term but attenuating influence of early learning experiences in the relationship with mother, and implications for how we think about the functioning of internal working models of attachment.

This paper reports on a randomized control trial involving children less than 3 years old and their mothers who were regarded at risk of maltreating their children by referral agencies. Mothers’ risk status derived from a heavy trauma burden (average exposure over the first 18 years of their lives to 10 possible adverse childhood experiences [ACEs] was >5), mental health challenges (15%–28% had experienced a prior psychiatric hospitalization), and prior removal of a child to foster care (20%). Mothers were randomly assigned to either a widely used parenting class known as Systematic Training for Effective Parenting (STEP) or the Group Attachment-Based Intervention (GABI), a multifamily 26-week treatment. The resulting mother–child pairs available for consideration in this baseline versus end-of-treatment report were 35 families in the STEP arm and 43 families in the GABI arm. The focus of this paper is the outcome measure of observed parent–child relationship assessed with the Coding of Interactive Behavior (Feldman, 1998) collected at baseline and end of treatment. In comparison to STEP, results indicated that GABI was linked to significant improvements in maternal supportive presence and dyadic reciprocity, and significant declines in maternal hostility and dyadic constriction (proxies for risk of child maltreatment). These medium-to large-sized effects remained significant even after controlling for mothers’ prior ACEs in analysis of covariance procedures. In addition, two small interaction effects of ACEs by treatment type were found, underlining the need for, and value of, treatments that are sensitive to parents’ traumatic histories.

The Adult Attachment Interview (AAI), developed and extensively tested in the domain of developmental psychology, has relevance to psychotherapy research. The authors compare and contrast the ways that social psychologists and developmental psychologists have operationalized the concept of attachment security and discuss corresponding implications for psychotherapy research. In addition, they provide an overview of the AAI and its development, reliability, and validation in developmental psychology and summarize recent work linking AAI responses with distinctive types of psychopathology. A summary of recent work showing the AAI to be a useful indicator of positive outcome in psychotherapy for adults with diverse problems, including depression, borderline personality disorder, and posttraumatic stress disorder, is provided.
