- Individual differences in aggressive behavior emerge in early childhood and predict persisting behavioral problems and disorders. Studies of antisocial and severe aggression in adulthood indicate substantial underlying biology. However, little attention has been given to genome-wide approaches of aggressive behavior in children. We analyzed data from nine population-based studies and assessed aggressive behavior using well-validated parent-reported questionnaires. This is the largest sample exploring children's aggressive behavior to date (N = 18,988), with measures in two developmental stages (N = 15,668 early childhood and N = 16,311 middle childhood/early adolescence). First, we estimated the additive genetic variance of children's aggressive behavior based on genome-wide SNP information, using genome-wide complex trait analysis (GCTA). Second, genetic associations within each study were assessed using a quasi-Poisson regression approach, capturing the highly right-skewed distribution of aggressive behavior. Third, we performed meta-analyses of genome-wide associations for both the total age-mixed sample and the two developmental stages. Finally, we performed a gene-based test using the summary statistics of the total sample. GCTA quantified variance tagged by common SNPs (10-54%). The meta-analysis of the total sample identified one region in chromosome 2 (2p12) at near genome-wide significance (top SNP rs11126630, P = 5.30 × 10(-8) ). The separate meta-analyses of the two developmental stages revealed suggestive evidence of association at the same locus. The gene-based analysis indicated association of variation within AVPR1A with aggressive behavior. We conclude that common variants at 2p12 show suggestive evidence for association with childhood aggression. Replication of these initial findings is needed, and further studies should clarify its biological meaning. © 2015 Wiley Periodicals, Inc.

- 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.

- Increased father–infant physical contact may promote early paternal caregiving. This randomized controlled trial, preregistered on https://osf.io/qwe3a, tested the effects of a soft baby carrier intervention on fathers’ parenting behavior and hormonal levels. Eighty first-time fathers of 2- to 4-month-old infants were randomly assigned to a baby carrier intervention group (n = 41 fathers) or a control group receiving an infant seat (n = 39 fathers). Fathers were instructed to use the baby carrier or seat for 3 weeks. Fathers’ sensitive parenting behavior, involvement, salivary oxytocin and cortisol basal levels and reactivity to interacting with the infant were assessed at pre-test (on average 2 weeks before the intervention) and at post-test (on average 1 week after the intervention period ended). The results showed that the intervention did not enhance fathers’ sensitive parenting or involvement. Involvement operationalized as hours spent with the infant decreased over time for fathers in the carrier condition compared to fathers in the control condition. The baby carrier intervention had no effect on fathers’ basal oxytocin or cortisol levels, nor did it affect fathers’ oxytocin or cortisol reactivity to interacting with their infant. Our findings indicate that 3 weeks of using a baby carrier does not have immediate beneficial effects on fathers’ parenting behavior or hormonal functioning as assessed here. Future research may examine whether infant carrying has beneficial effects on the longer term or in different groups of fathers, and how fathers’ infant carrying affects their infants.

- BackgroundUnderstanding how child maltreatment is passed down from one generation to the next is crucial for the development of intervention and prevention strategies that may break the cycle of child maltreatment. Changes in emotion recognition due to childhood maltreatment have repeatedly been found, and may underly the intergenerational transmission of child maltreatment.ObjectiveIn this study we, therefore, examined whether the ability to recognize emotions plays a role in the intergenerational transmission of child abuse and neglect.Participants and settingA total of 250 parents (104 males, 146 females) were included that participated in a three-generation family study.MethodParticipants completed an emotion recognition task in which they were presented with series of photographs that depicted the unfolding of facial expressions from neutrality to the peak emotions anger, fear, happiness, and sadness. Multi-informant measures were used to examine experienced and perpetrated child maltreatment.ResultsA history of abuse, but not neglect, predicted a shorter reaction time to identify fear and anger. In addition, parents who showed higher levels of neglectful behavior made more errors in identifying fear, whereas parents who showed higher levels of abusive behavior made more errors in identifying anger. Emotion recognition did not mediate the association between experienced and perpetrated child maltreatment.ConclusionsFindings highlight the importance of distinguishing between abuse and neglect when investigating the precursors and sequalae of child maltreatment. In addition, the effectiveness of interventions that aim to break the cycle of abuse and neglect could be improved by better addressing the specific problems with emotion processing of abusive and neglectful parents.

Forskningsöversikt (refereegranskat)abstract
- Disorganized/Disoriented (D) attachment has seen widespread interest from policy makers, practitioners, and clinicians in recent years. However, some of this interest seems to have been based on some false assumptions that (1) attachment measures can be used as definitive assessments of the individual in forensic/child protection settings and that disorganized attachment (2) reliably indicates child maltreatment, (3) is a strong predictor of pathology, and (4) represents a fixed or static trait of the child, impervious to development or help. This paper summarizes the evidence showing that these four assumptions are false and misleading. The paper reviews what is known about disorganized infant attachment and clarifies the implications of the classification for clinical and welfare practice with children. In particular, the difference between disorganized attachment and attachment disorder is examined, and a strong case is made for the value of attachment theory for supportive work with families and for the development and evaluation of evidence-based caregiving interventions.

The Role of Psychopathology and Emotion Regulation in the Intergenerational Transmission of Childhood Abuse : A Family Study
- 2024
-
Ingår i: Child Maltreatment. - 1077-5595 .- 1552-6119.

Tidskriftsartikel (refereegranskat)abstract
- Previous studies have shown that parents with a history of childhood abuse are at increased risk of perpetrating child abuse. To break the cycle of childhood abuse we need to better understand the mechanisms that play a role. In a cross-sectional extended family design including three generations (N = 250, 59% female), we examined the possible mediating role of parental psychopathology and emotion regulation in the association between a history of childhood abuse and perpetrating child abuse. Parents’ own history of childhood abuse was associated with perpetrating abuse toward their children, and externalizing (but not internalizing) problems partially mediated this association statistically. Implicit and explicit emotion regulation were not associated with experienced or perpetrated abuse. Findings did not differ across fathers and mothers. Findings underline the importance of (early) treatment of externalizing problems in parents with a history of childhood abuse, to possibly prevent the transmission of child abuse.

Tidskriftsartikel (refereegranskat)abstract
- In Wertz et al. (2019), parents' polygenic scores of educational attainment (PGS-EA) predicted parental sensitive responses to the child's needs for support, as observed in a dyadic task (i.e., observed sensitivity). We aimed to replicate and expand these findings by combining longitudinal data, child genotype data and several polygenic scores in the Generation R Study. Mother–child dyads participated in two developmental periods, toddlerhood (14 months old; n = 648) and early childhood (3–4 years old, n = 613). Higher maternal PGS-EA scores predicted higher observed sensitivity in toddlerhood (b = 0.12, 95% CI 0.03, 0.20) and early childhood (b = 0.16, 95% CI 0.08, 0.24). Child PGS-EA was significantly associated with maternal sensitivity in early childhood (b = 0.11, 95% CI 0.02, 0.21), and the effect of maternal PGS-EA was no longer significant when correcting for child PGS-EA. A latent factor of PGSs based on educational attainment, intelligence (IQ) and income showed similar results. These polygenic scores might be associated with maternal cognitive and behavioral skills that help shape parenting. Maternal PGSs predicted observed sensitivity over and above the maternal phenotypes, showing an additional role for PGSs in parenting research. In conclusion, we replicated the central finding of Wertz et al. (2019) that parental PGS-EA partially explains parental sensitivity. Our findings may be consistent with evocative gene–environment correlation (rGE), emphasizing the dynamic nature of parenting behavior across time, although further research using family trios is needed to adequately test this hypothesis.

Tidskriftsartikel (refereegranskat)abstract
- This study examined whether neural processing of infant cry sounds changes across the transition to fatherhood (i.e., from the prenatal to postnatal period), and examined whether an interaction-based prenatal intervention modulated these changes. Furthermore, we explored whether postnatal activation in brain regions showing transition or intervention effects was associated with sensitive care and involvement. In a randomized controlled trial, 73 first-time expectant fathers were enrolled, of whom 59 had at least 1 available fMRI scan. Intervention and transition effects on cry processing were analyzed in the amygdala and superior frontal gyrus (SFG) using linear mixed effect models with all available data and with intent-to-treat analyses. Further, exploratory whole-brain analyses were performed. ROI analyses suggest that the transition to fatherhood is characterized by decreasing activation in response to cry vs control sounds in the amygdala but not SFG. Exploratory whole-brain analyses also show a decrease in activation over the transition to fatherhood in the sensorimotor cortex, superior lateral occipital cortex, hippocampus, and regions of the default mode network. In the putamen and insula, larger decreases were found in fathers with more adverse childhood caregiving experiences. In regions showing transitional changes, higher postnatal activation was associated with more concurrent parenting sensitivity. No effects of the intervention were found. The decrease in activation from the pre- to postnatal period may reflect fathers’ habituation to cry sounds over repeated exposures. The positive association between postnatal neural activation and paternal sensitive care suggest that continued sensitivity to cry sounds may be conducive to parenting quality.
