In the past decades, conceptualizations of genetic and neurobiological factors have become increasingly detailed. Development of our conceptualizations of environmental factors, in contrast, is lacking behind. Environmental adversity is usually conceptualized as one rather global factor, including, for example, both structural factors (e.g. poverty and racism) and psychosocial factors (e.g. parental violence or neglect). Or, as Chow et al. (2025) in this issue put it ?There is not yet a consensus on the best way to conceptualise adverse childhood experience?.

This development is essential for unravelling the mechanisms that shape child and adolescent mental health problems.

Oral language intervention in the late primary school years is effective: evidence from a randomised control trial / Arne LERVAG ; Charles HULME in Journal of Child Psychology and Psychiatry, 66-6 (June 2025)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 66-6 (June 2025) . - p.775-784 Titre : Oral language intervention in the late primary school years is effective: evidence from a randomised control trial Type de document : Texte imprimé et/ou numérique Auteurs : Arne LERVAG, Auteur ; Charles HULME, Auteur Article en page(s) : p.775-784 Langues : Anglais (eng) Mots-clés : Language  RCT  education  primary school intervention Index. décimale : PER Périodiques Résumé : Background Oral language skills provide the foundation for formal education, and children may require language support over an extended period of time to maximise their education potential. Most work on language intervention, however, has focussed on the preschool or early school years. Here, we describe the development and evaluation of the Oral Language for Literacy Intervention (OLLI) programme which is designed to support children with weak language skills in the later primary school years. Methods We conducted a randomised control trial in 33 schools (50 classrooms). The language skills of all 8?9?year-old children in each participating classroom (n?=?1,423) were assessed using an automated app (LanguageScreen). The six children with the weakest LanguageScreen scores within each classroom (n?=?296) were randomly allocated to the intervention (n?=?148) or control group (n?=?148). The children in the intervention group received the OLLI programme delivered in individual and small group sessions over 20?weeks. Children in the control group received their typical teaching. Results Children receiving the OLLI programme made significantly larger gains than children in the control group on a preregistered latent variable reflecting standardised measures of oral language ability (d?=?0.38) and on a measure of their written expression (d?=?0.42). Conclusions These findings have important implications for improving educational attainment in children in the late primary school years. The OLLI programme is designed to be deliverable at scale and is of relatively low cost.

Neural correlates of children with avoidant restrictive food intake disorder symptoms: large-scale neuroanatomical analysis of a paediatric population / Holly A. HARRIS ; Gordon D.

Despite burgeoning research, few studies to date have explored the underlying neurobiology of ARFID. Research examining the neural underpinnings of ARFID can greatly assist in understanding different mechanisms that play disorder-specific roles. Methods We studied a total of 1,977 10-year-old participants from the Generation R Study, a population-based Dutch cohort, to cross-sectionally examine neuroanatomical differences between those with versus without ARFID-like symptoms. Children were classified with versus without ARFID symptoms using the ARFID Index, a validated evaluative tool comprised of parent-reported and researcher-assessed measurements of picky eating, energy intake, diet quality, growth and psychosocial impact to characterise ARFID symptoms in the paediatric population. Global and regional values of surface area, cortical thickness, and volume from T1-weighted structural magnetic resonance imaging (MRI) scans in those with ARFID symptoms were compared with children not exhibiting symptoms. Results We identified 121 (6.1%) individuals with ARFID symptoms relative to 1,865 (93.9%) individuals without ARFID symptoms. Neuroanatomical findings identified significantly greater frontal (p?=?.00743; d?=?0.21) and superior frontal (p?=?6.56E-04; d?=?0.28) cortical thickness among children with ARFID symptoms. Conclusions This first large-scale study of the neural correlates of ARFID identified greater thickness of frontal cortical regions in children with ARFID symptoms, suggesting a role for executive function in the aetiology of the condition.

Heritability of children's Secure Base Script Knowledge in middle childhood: a twin study with the Attachment Script Assessment / Annemieke M. WITTE ; Marinus H. VAN IJZENDOORN ; Marian J. BAKERMANS-KRANENBURG in Journal of Child Psychology and Psychiatry, 66-6 (June 2025)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 66-6 (June 2025) . - p.796-804 Titre : Heritability of children's Secure Base Script Knowledge in middle childhood: a twin study with the Attachment Script Assessment Type de document : Texte imprimé et/ou numérique Auteurs : Annemieke M. WITTE, Auteur ; Marinus H. VAN IJZENDOORN, Auteur ; Marian J. BAKERMANS-KRANENBURG, Auteur Article en page(s) : p.796-804 Langues : Anglais (eng) Mots-clés : Attachment  heritability  ACE models  twins  Secure Base Script Knowledge Index. décimale : PER Périodiques Résumé : Background Are individual differences in attachment security inborn or shaped by the social environment? In infancy and early childhood, the evidence points to a substantial role of the environment, but a large twin study in early adolescence showed considerable heritability. Here we examined the twin heritability of attachment in middle childhood. We hypothesized that in middle childhood some heritability would emerge. Furthermore, we expected a role for cognitive and language abilities in explaining variance in attachment in middle childhood, partly related to the measurement of attachment, and we therefore examined associations with IQ. Methods This pre-registered study included 415 same-sex twin pairs (52% girls, 58% monozygotic) between 8 and 11?years old (M?=?9.59, SD?=?0.79). Participants were recruited from an experimental cohort-sequential study including two age-overlapping longitudinal cohorts. Secure Base Script Knowledge was assessed with the Middle Childhood Attachment Script Assessment . Zygosity of the twins was determined using DNA samples. In the younger cohort, cognitive development was assessed with the Dutch version of the Wechsler Preschool and Primary Scale of Intelligence . In the older cohort, the Dutch version of the Wechsler Intelligence Scale for Children was used . Results Significant additive heritability (38%) was found in the absence of a common environment component. This result diverges from findings in infancy and early childhood and aligns with the results in early adolescence. Conclusions The gene?environment correlation hypothesis suggesting that older children more actively shape their experiences in social contexts may offer a plausible explanation for the heritability of attachment in middle childhood. In middle childhood this mechanism might tip the balance toward a larger role for additive genetics. Larger longitudinal twin studies are needed to replicate the heritability of attachment after preschool age.

Methods We conducted a multicentre, two-arm parallel group randomised controlled trial in eight large National Health Service Trusts in England providing multidisciplinary specialist Child and Adolescent Mental Health Services (CAMHS). Participants (5?17?year-olds with emotional difficulties referred to CAMHS) were randomly assigned (1:1), following referral receipt, to either receive the DAWBA and assessment-as-usual (intervention group) or assessment-as-usual (control group). Data were self-reported by participants (parents and/or young person, depending on age) at baseline, 6- and 12-month post-randomisation and collected from clinical records up to 18?months post-randomisation. The primary outcome was a clinician-made diagnosis decision about the presence of an emotional disorder within 12?months of randomisation. Trial registration: ISRCTN15748675. Results In total, 1,225 children and young people (58% female sex) were randomised (615 intervention; 610 control). Adherence to the intervention (full/partial completion) was 80% (494/615). At 12?months, 68 (11%) participants in the intervention group received an emotional disorder diagnosis versus 72 (12%) in the control group (adjusted risk ratio (RR) 0.94 [95% CI 0.70, 1.28]). The intervention was not cost effective. There was no evidence of any differences between groups for service-related or participant-reported secondary outcomes, for example, CAMHS acceptance of the index referral (intervention 277 (45%) versus control 262 (43%); RR: 1.06 [95% CI: 0.94, 1.19]) was similar between groups. Conclusions As delivered in this pragmatic trial, we found no evidence for the effectiveness or cost effectiveness of using a Standardised Diagnostic Assessment tool in aiding the detection of emotional disorders or clinical outcomes in clinically referred children and young people. Despite regular efforts to encourage clinicians to view the DAWBA report and consider its findings as part of assessment and diagnosis, we did not collect data on usage and therefore cannot confirm the extent to which clinicians did this. As a pragmatic trial that aimed to test the effectiveness of incorporating the DAWBA into usual practice and clinical care, our study found that, in the format as delivered in this trial, there was no impact on diagnosis or clinical outcomes.

Childhood adversity is associated with reduced threat-safety discrimination and increased fear generalization in 12- to 16-year-olds / Aleksandra LECEI ; Maarten JACKERS ; Lise JENNEN ; Koen SCHRUERS ; Bram VERVLIET ; Bart BOETS ; Ruud VAN WINKEL in Journal of Child Psychology and Psychiatry, 66-6 (June 2025)

Altered threat-related information processing has been put forward as a potential process underlying the association between childhood adversity and psychiatric disorders, with previous research providing support for decreased discrimination between threat and safety cues, in both children and adults exposed to adversity. This altered threat-safety discrimination has been hypothesized to stem from increased generalization of fear, yet to date, this hypothesis has not been tested in youth. Methods Here, we investigate whether childhood adversity is associated with fear generalization during adolescence. 119 adolescents between 12 and 16?years of age (mean?=?13.95), of whom 63 exposed to childhood adversity, completed a fear generalization paradigm. Fear conditioning was assessed through trial-by-trial US expectancy ratings and post-experimental ratings of fear, valence and arousal. Additionally, we administered a perceptual discrimination task to assess the potential impact of perceptual discrimination abilities upon fear generalization. Results In line with our hypotheses, results showed that childhood adversity is associated with (1) reduced threat-safety differentiation during fear acquisition and (2) increased fear generalization in both boys and girls, albeit to a different extent, as boys showed more generalization towards safety cues while girls showed more generalization towards dangerous cues. Moreover, this overgeneralization of fear could not be attributed to group differences in perceptual discrimination. Conclusions Altered fear learning may be an important process through which adversity increases risk for the development of psychopathology. Longitudinal research is essential to elucidate risk and resilience patterns following childhood adversity.

The final sample consisted of all children born in Sweden between 2001 and 2007 who could be linked to both of their biological parents, excluding those who died or emigrated (n?=?631,695). Follow-up was completed December 31, 2013. Cox proportional-hazards models for survival analysis were used to identify the predictors that increased the risk of receiving a clinical diagnosis of ADHD from 3 to 5?years. Hazard ratios (HR) with 95% confidence intervals (CI) were presented for each of the 41 selected predictors covering early-onset psychiatric comorbidities, nonpsychiatric medical conditions, parental history and perinatal factors. Results At the end of follow-up, 1,686 preschoolers (2.7% of the whole sample) had received a diagnosis of ADHD. We found that 39 out of 41 predictors were associated with increased risk of a later diagnosis of preschool ADHD. Novel associations with preschool ADHD diagnosis were found for gastroesophageal reflux disease (HR?=?3.48), premature contractions during pregnancy (HR?=?2.03), and criminal conviction history from any parent (HR?=?2.14). Conclusions A large number of novel and well-established predictors of preschool ADHD diagnosis were identified. This broad set of early predictors may direct future clinical research and assist in early identification of preschool ADHD.

In this longitudinal study, we investigated the impact of maltreatment on behavioural and neural indices of reward learning in volatile environments and examined associations with future psychopathology assessed 18?months later. Methods Thirty-seven children and adolescents with documented histories of maltreatment (MT group) and a carefully matched group of 32 non-maltreated individuals (NMT group) aged 10?16 were presented with a probabilistic reinforcement learning task featuring a phase of stable and a phase of volatile reward contingencies. Brain activation and connectivity were assessed simultaneously using functional magnetic resonance imaging (fMRI). Computational models were used to extract individual estimates of learning rates and temperature, and neural signals in prespecified regions of interest were analysed during volatile and stable environments. In regression analyses, behavioural measures and neural signals at baseline were used to predict psychological symptoms at follow-up. Results The MT group showed lower behavioural exploration, which predicted decreased internalising symptoms at follow-up. The MT group had lower activation in the orbitofrontal cortex (OFC) during outcome delivery in volatile relative to stable contexts. OFC connectivity with an area in the mid-cingulate cortex was also lower during outcome processing, which predicted higher general psychopathology at follow-up. Conclusions These findings are consistent with the notion that low exploratory behaviour following childhood maltreatment is potentially a protective adaptation against internalising symptoms, while disrupted neural processing of reward learning in volatile environments may index latent vulnerability to mental illness.

Prevention of self-harm should be informed by knowledge about risk factors (e.g. socio-demographic indices), characteristics (i.e. motivation for self-harm and help-seeking behaviours), as well as relative aetiological genetic and environmental processes. Previous twin studies evidence both genetic and environmental influences on self-harm. However, to date, there has been no genetically informed research on self-harm aetiology across development, nor studies identifying risk factors for initiating self-harm at a younger age. Methods We examined self-harm in the Twins Early Development Study, a birth cohort twin study. Using clustered regression models, we tested associations of socio-demographic factors and victimisation with lifetime self-harm and age of self-harm initiation, both reported at 21. To investigate stability and/or change in genetic and environmental influences on self-harm we interpreted a multivariate Cholesky decomposition across ages ?16, 21, and 26. Results Self-harm was more common in adolescence than early adulthood, and the incidence of self-harm in early adulthood was low (1.4%). The most common motivation for self-harm was ?to get relief from a terrible state of mind? (83.4%). Independent predictors of self-harm and earlier initiation of self-harm were being female, belonging to a gender and/or sexual minority group, and experience of bullying victimisation. Sexual minority status was still significantly associated with self-harm after controlling for familial factors in co-twin control analyses. The Cholesky decomposition showed stability in genetic influences and innovation in non-shared environmental influences on self-harm. Conclusions Adolescence should be a key period for self-harm interventions. Women, sexual, and gender minorities, and those experiencing victimisation may need targeted support early in adolescence. Furthermore, it should be acknowledged that different individuals can be at risk at different stages as environmental factors influencing self-harm change across time.

We used data-driven methods across two populations to examine (a) if there were meaningful dimensions underlying ACEs and (b) whether dimensions were differentially associated with increased risk of adolescent psychopathology. Methods Participants were 18,539 British children from the UK Millennium Cohort Study (MCS) and 11,876 American children from the US Adolescent Brain Cognitive Development Study (ABCD). A wide range of ACEs (e.g., abuse, neglect, parental psychopathology, peer victimisation) were measured prospectively from infancy to mid-adolescence using interviews and questionnaires. Internalising and externalising symptoms were assessed with child and/or parent reports during adolescence. Results Our preregistered exploratory factor analysis revealed four latent dimensions in the MCS (parental threat, deprivation, victimisation, and parental discipline) and ABCD (parental threat, deprivation, victimisation, and traumatic events). All dimensions except deprivation were associated with increased risk for internalising and externalising symptoms. Over and above the other dimensions, victimisation was more strongly associated with internalising (MCS ??=?.34, 95% CI 0.33?0.36; ABCD ??=?.11, 95% CI 0.10?0.13) and externalising (MCS ??=?.31, 95% CI 0.30?0.33; ABCD ??=?.13, 95% CI 0.11?0.15) symptoms. Conclusions Across two distinct populations, we found that ACEs can be captured by common underlying dimensions of parental threat, deprivation, and victimisation, as well as additional sample-specific dimensions. Our findings expand dimensional theories of childhood adversity by suggesting that in addition to threat and deprivation, victimisation is a distinct dimension of adversity that has the strongest associations with adolescent psychopathology.

However, empirical evidence on this relationship remains uncertain, as most studies are based on cross-sectional designs. Therefore, this study aimed to examine this temporal relationship using longitudinal data from a birth cohort. Methods A retrospective cohort study was conducted using data from Wave I (starting at 6?months old, 2005?2006) to Wave IV (up to 5?years old, 2010?2011) of the Taiwan Birth Cohort Study. A total of 19,721 pairs completed the four-wave interviews and provided information on infant feeding, medical history, ADHD occurrence, and sociodemographic characteristics. An extended Cox model with time-dependent covariates was used to examine this association. Results In total, 207 infants developed ADHD during the 54-month observational period, with an estimated cumulative incidence of 5.56 per 1,000 person-years. The average breastfeeding duration was approximately 2 months. With complementary feeding, rice solid food (HR?=?0.73) was found to be a protective factor against developing ADHD. Significantly associated factors for increasing ADHD risk included males, lower family income, low birth weight, maternal weight, advanced maternal age, child gastrointestinal disease, child seizures, maternal heart disease, and paternal diabetes mellitus. Conclusions Complementary feeding within 6 months is important to protect infants from developing ADHD. The beneficial effect of breastfeeding within 6 months was not observed while controlling for other risk factors. However, owing to the limitation of a smaller number of ADHD cases, further studies should rely on larger observational periods.

SONUGA-BARKE, Auteur Article en page(s) : p.892-905 Langues : Anglais (eng) Mots-clés : ADHD  development  delay aversion  preschoolers  parenting  social factors Index. décimale : PER Périodiques Résumé : Background Attention-deficit/hyperactivity disorder (ADHD) is commonly attributed to neuro-cognitive deficits of genetic and/or prenatal/perinatal environmental origins. Sonuga-Barke proposed an alternative formulation, suggesting that ADHD behaviors are functional expressions of delay aversion?a strong motivational disposition to avoid or escape negative affective states evoked by delay. It is hypothesized that the strength of this disposition, though neuro-biologically rooted, is exacerbated by early negative social interactions during waiting-related encounters. This paper reports findings from an initial proof-of-concept study that specifically tests this hypothesis in a nonclinical sample. Methods Preschoolers (n?=?112; mean age?=?46.2?months) and their parents from London, UK, and Hong Kong participated in a longitudinal study. The Parent?Child Delay Frustration Task (PC-DeFT) and two nonwaiting control tasks were administered at baseline. Children's performance, behavioral and emotional responses, and parents' reactions were observed. Teachers rated children's ADHD behaviors and delay aversion at baseline and follow-up (12?18?months later). Results At baseline, children's maladaptive performance and parental negative reactions during the PC-DeFT were correlated with each other and with teacher ratings of ADHD and delay aversion. Negative parental reactions during the PC-DeFT at baseline predicted an increase in teacher-rated ADHD behaviors at follow-up, but similar associations were not observed for baseline parental responses in the nonwaiting tasks. The increase in child ADHD symptoms associated with negative parental reactions at baseline was statistically mediated by delay aversion. These longitudinal effects were consistent across the UK and HK samples. Conclusions The findings provide the first evidence that parent's negative reactions to preschooler's attempts to manage delay are associated with increases in ADHD behaviors overtime, and linked to delay aversion increases. They underscore the potential significance of the early social environment as a contributor to developmental trajectory of ADHD behaviors. Future studies with clinical samples over an extended time-frame using a range of different aversive environments (i.e. difficult tasks to complete) are indicated.

The study by Kochanska and colleagues shows this in several ways. First, it offers a model for constructing theoretically guided causal models built on longitudinal research enlisting multiple predictors of developing theory of mind that can be examined in concert. Second, the findings invite deeper consideration of the processes by which theory of mind emerges by unpacking the relational predictors highlighted in this and other studies. In particular, examining the characteristics of early conversation focused on the child's experiences and mental states and studying the coordination of subjective states in parent?child interaction are each warranted avenues. Third, enlisting fathers and mothers into this inquiry broadens the range of relational partners contributing to young children's developing understanding of the mind.

C. POLDERMAN, Auteur ; Thalia C. ELEY, Auteur Article en page(s) : p.910-927 Langues : Anglais (eng) Mots-clés : Adolescence  psychopathology  behavioural genetics  genomics Index. décimale : PER Périodiques Résumé : Background Mental health problems and traits capturing psychopathology are common and often begin during adolescence. Decades of twin studies indicate that genetic factors explain around 50% of individual differences in adolescent psychopathology. In recent years, significant advances, particularly in genomics, have moved this work towards more translational findings. Methods This review provides an overview of the past decade of genetically sensitive studies on adolescent development, covering both family and genomic studies in adolescents aged 10?24?years. We focus on five research themes: (1) co-occurrence or comorbidity between psychopathologies, (2) stability and change over time, (3) intergenerational transmission, (4) gene?environment interplay, and (5) psychological treatment outcomes. Results First, research shows that much of the co-occurrence of psychopathologies in adolescence is explained by genetic factors, with widespread pleiotropic influences on many traits. Second, stability in psychopathology across adolescence is largely explained by persistent genetic influences, whereas change is explained by emerging genetic and environmental influences. Third, contemporary twin-family studies suggest that different co-occurring genetic and environmental mechanisms may account for the intergenerational transmission of psychopathology, with some differences across psychopathologies. Fourth, genetic influences on adolescent psychopathology are correlated with a wide range of environmental exposures. However, the extent to which genetic factors interact with the environment remains unclear, as findings from both twin and genomic studies are inconsistent. Finally, a few studies suggest that genetic factors may play a role in psychological treatment response, but these findings have not yet been replicated. Conclusions Genetically sensitive research on adolescent psychopathology has progressed significantly in the past decade, with family and twin findings starting to be replicated at the genomic level. However, important gaps remain in the literature, and we conclude by providing suggestions of research questions that still need to be addressed.
