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: Supporting families in the first 1,000 days of life – a balancing act / Maartje P.C.M. LUIJK in Journal of Child Psychology and Psychiatry, 66-10 (October 2025)

In no other period of life are more biological and developmental milestones met than in the first 1,000 days after conception. All organs and systems are formed, and children start to discover the world, learn whom to trust and where to find comfort in times of distress. Evidence from biological, psychological, social and economic research shows that the environment in the first 1,000 days significantly impacts a person's ability to reach their full potential. Children who grow up in unpredictable and unsafe environments often struggle with the consequences for the rest of their lives. Investments in this critical period of human development have proven to be the most cost-effective way to improve lifelong health and well-being. Therefore, this period has gained interest both in political debate and society at large. In this contribution, we demonstrate that while the focus on the first 1,000 days is scientifically sound and historically grounded, it is time to reflect on its societal impact. We focus on its unintended negative consequences for parental well-being. Evidence for the importance of the first 1,000 days should drive collective action rather than reinforce individual blame. Parenting is not just a private matter; governments have a duty to provide parents with the resources to give their children the best start in life.

Methylation matters: FK506 binding protein 51 (FKBP5) methylation moderates the associations of FKBP5 genotype and resistant attachment with stress regulation / Rosa H. MULDER in Development and Psychopathology, 29-2 (May 2017)

VAN IJZENDOORN, Auteur Article en page(s) : p.491-503 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The parent–child attachment relationship plays an important role in the development of the infant's stress regulation system. However, genetic and epigenetic factors such as FK506 binding protein 51 (FKBP5) genotype and DNA methylation have also been associated with hypothalamus–pituitary–adrenal axis functioning. In the current study, we examined how parent–child dyadic regulation works in concert with genetic and epigenetic aspects of stress regulation. We study the associations of attachment, extreme maternal insensitivity, FKBP5 single nucleotide polymorphism 1360780, and FKBP5 methylation, with cortisol reactivity to the Strange Situation Procedure in 298 14-month-old infants. The results indicate that FKBP5 methylation moderates the associations of FKBP5 genotype and resistant attachment with cortisol reactivity. We conclude that the inclusion of epigenetics in the field of developmental psychopathology may lead to a more precise picture of the interplay between genetic makeup and parenting in shaping stress reactivity.

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.

Preschool family irregularity and the development of sleep problems in childhood: a longitudinal study / Maria Elisabeth KOOPMAN-VERHOEFF in Journal of Child Psychology and Psychiatry, 60-8 (August 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-8 (August 2019) . - p.857-865 Titre : Preschool family irregularity and the development of sleep problems in childhood: a longitudinal study Type de document : texte imprimé Auteurs : Maria Elisabeth KOOPMAN-VERHOEFF, Auteur ; Fadila SERDAREVIC, Auteur ; Desana KOCEVSKA, Auteur ; F.

LUIJK, Auteur Article en page(s) : p.857-865 Langues : Anglais (eng) Mots-clés : Family chaos  accelerometer  actigraphy  developmental psychopathology  family routines  longitudinal  sleep duration Index. décimale : PER Périodiques Résumé : BACKGROUND: Previous studies have shown that poor family environments are related to more sleep problems; however, little is known about how family irregularity in early life affects the development of sleep problems over childhood using objective sleep measures. The current study tests the hypothesis that early family irregularity contributes to the development of sleep problems. METHODS: This population-based study comprises 5,443 children from the Generation R Study. Family irregularity was measured with seven maternal-reported questions on family routines when children were 2 and 4 years old. Mothers reported on sleep problems at child age 3, 6, and 10 years, whereas children completed questionnaires on sleep problems at age 10. Additionally, we used tri-axial wrist accelerometers for five nights in 851 children (mean age 11.7 years) to assess sleep objectively. RESULTS: Family irregularity was associated with more mother- and child-reported sleep problems at ages 3, 6, and 10 years as well as with a shorter sleep duration and later objective sleep onset, but not with sleep efficiency or waking time. The association between family irregularity and multi-informant subjective sleep problems at age 10 years was mediated by mother-reported child psychopathology at age 6 years. CONCLUSIONS: Our findings show a long-term robust association of preschool family irregularity with more sleep problems during childhood as well as shorter sleep duration and later sleep onset as measured objectively with actigraphy. In part, these sleep problems were associated with family irregularity by way of child psychopathology. These findings suggest that interventions improving preschool family irregularity, which are targeted to reduce child psychopathology, may also impact the development of sleep problems beneficially.
