Parenting was assessed using observational rating scales for parental sensitivity (Ainsworth, Bell, & Stayton, 1974), and infant attachment was assessed with the Strange Situation Procedure. Results:  We found no consistent additive genetic associations for attachment security and attachment disorganization. However, specific tests revealed evidence for a codominant risk model for COMT Val158Met, consistent across both samples. Children with the Val/Met genotype showed higher disorganization scores (combined effect size d = .22, CI = .10–.34, p < .001). Gene-by-environment interaction effects were not replicable across the two samples. Conclusions:  This unexpected finding might be explained by a broader range of plasticity in heterozygotes, which may increase susceptibility to environmental influences or to dysregulation of emotional arousal. This study is unique in combining the two largest attachment cohorts with molecular genetic and observed rearing environment data to date.

Editorial Perspective: On the need for clarity about attachment terminology / Marije L. VERHAGE in Journal of Child Psychology and Psychiatry, 64-5 (May 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-5 (May 2023) . - p.839-843 Titre : Editorial Perspective: On the need for clarity about attachment terminology Type de document : Texte imprimé et/ou numérique Auteurs : Marije L. VERHAGE, Auteur ; Anne THARNER, Auteur ; Robbie DUSCHINSKY, Auteur ; Guy BOSMANS, Auteur ; R. M. Pasco FEARON, Auteur Article en page(s) : p.839-843 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : 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, the feedback loop from practice to research and the dialogue between attachment researchers in developmental psychology and in social psychology. This paper pinpoints the difficulties arising from the existence of multiple versions of 'attachment theory' that use exactly the same terms, held by communities that assume that they are referring to the same thing and with little infrastructure to help them discover otherwise. When we talk past one another, the different communities with a stake in knowledge of attachment are obstructed from genuinely learning from one another, drawing on their respective strengths and pursuing collaborations. One factor contributing to this situation has been the use of attachment terminology with technical meanings, but often without setting out clear definitions. We here introduce a guide to attachment terminology used by the academic community, which has recently been published on the website of the Society for Emotion and Attachment Studies. The guide is meant for researchers, clinicians and everyone concerned with attachment to increase understanding of the technical meaning of important terminology used by researchers, and support the quality of discussions between researchers, and between researchers and clinicians and other publics.

Prenatal predictors of childhood anxiety disorders: An exploratory study of the role of attachment organization / Megan GALBALLY in Development and Psychopathology, 35-3 (August 2023)

What is not understood is whether early life stress predictors of CAD might be both mediated by infant cortisol reactivity and moderated by infant attachment status. To address this question, this exploratory study draws on 190 women recruited in early pregnancy and followed together with their children until 4 years of age. Early life stress is operationalized as maternal depression measured using the Structured Clinical Interview for the DSM, Childhood Trauma Questionnaire, Parenting Stress Index, and antenatal maternal hair cortisol concentrations. Infant cortisol reactivity was measured at 12 months together with the Strange Situation Procedure and CAD assessed at 4 years of age using the Preschool Age Psychiatric Assessment. There was no direct association between attachment classification and CAD. Furthermore, infant cortisol reactivity neither mediated nor attachment moderated the association of early life stress predictors and CAD. However, only for infants with organized attachment classifications, higher maternal antenatal depression, and hair cortisol were associated with a higher risk of CAD.
