JANSEN, Auteur Article en page(s) : p.801-803 Langues : Anglais (eng) Mots-clés : Mental health  societal influence  bidirectional Index. décimale : PER Périodiques Résumé : Child psychology and psychiatry have long examined how the environments in which children grow up shape their mental health. Contemporary frameworks on children's mental health emphasize the causal influence of environmental factors and how these influences vary across children by their individual characteristics. The present issue illustrates the breadth of relevant environmental influences, ranging from parental knowledge to neighborhood disadvantage and the COVID-19 pandemic. Yet, most empirical research in child psychology and psychiatry has focused on proximal environmental factors; broader societal factors ? such as geopolitical tensions, climate change, and socioeconomic inequality ? remain comparatively underexplored. In addition, most research on societal factors prioritizes societal factors as causes of child mental health. The impact of child mental health on societal developments has received far less attention. This Editorial advocates for greater integration of societal factors into research on child mental health and highlights the urgent need to examine the bidirectional relation between society and children, including how research contributes to societal change.

A person-centered and genetically informed approach toward characterizing multidomain resilience to neighborhood disadvantage in youth / Jessica L. BEZEK in Journal of Child Psychology and Psychiatry, 67-6 (June 2026)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 67-6 (June 2026) . - p.804-815 Titre : A person-centered and genetically informed approach toward characterizing multidomain resilience to neighborhood disadvantage in youth Type de document : texte imprimé Auteurs : Jessica L.

HYDE, Auteur Article en page(s) : p.804-815 Langues : Anglais (eng) Mots-clés : Resilience  neighborhood  parenting  behavioral genetics  latent profile analysis Index. décimale : PER Périodiques Résumé : Background Examining resilience to adversity across multiple behavioral domains (e.g., psychological well-being, social functioning) can better characterize positive development and inform novel prevention and intervention efforts. However, few studies have employed person-centered methods to examine individual profiles of resilience across multiple domains in youth. Further, research exploring contextual predictors of resilience has rarely used genetically informed designs, which are critical for eliminating potential confounds. Methods The current study employed latent profile analysis (LPA) to extract profiles of resilience across psychological, social, and academic domains in 708 adolescent twins exposed to neighborhood disadvantage, a pervasive form of early life adversity. Next, associations between profile membership and parenting, peer, and neighborhood social processes were examined. Lastly, co-twin control analyses were conducted to explore whether associations between resilience profile membership and social processes were environmental versus genetic in origin. Results Youth were grouped into three resilience profiles: (1) High Multidomain Resilience (63%), (2) Low Psychological Resilience, High Social Resilience (19%), and (3) Low Multidomain Resilience (18%). Profiles differed in experiences of parenting (i.e., parental involvement, conflict), peer characteristics (i.e., friend drug-related behaviors, popularity), and neighborhood processes (i.e., social cohesion, informal social control, positive social norms). Follow-up analyses within-twin pairs revealed that the association between higher resilience and parenting (higher nurturance, lower conflict) was at least partially environmental in origin. Conclusions Youth show distinct profiles of resilience across psychological, social, and academic domains, which are uniquely related to processes at the family, peer, and neighborhood level. Further, the association between resilience and parenting is in part environmentally mediated, suggesting a modifiable pathway to boost resilience in adolescents exposed to neighborhood disadvantage.

Gestational kynurenine metabolites mediate effects of pregnancy adiposity on child negative affect / Hanna C. GUSTAFSSON in Journal of Child Psychology and Psychiatry, 67-6 (June 2026)

Yet the mechanisms underlying this association remain poorly understood, limiting our ability to design effective interventions. We hypothesize that alterations in the kynurenine system of the pregnant woman help to explain this association. Methods Participants were recruited during pregnancy with repeated assessments through 24?months postpartum. Maternal adiposity was assessed using air displacement plethysmography. Liquid chromatography tandem mass spectrometry was used to measure kynurenine system metabolites in maternal plasma. Child negative affect was assessed via maternal report at 6, 12, and 24 months. Results Participants (N?=?302) included mother?child dyads (70% non-Hispanic White, 51% female). The ratio of picolinic to quinolinic acid (PA:QA) predicted child fear (??=??.15, 95% CI ?0.27, ?0.03, p?=?.02) and sadness (??=??.14, 95% CI ?0.28, 0.003, p?=?.045) at 6?months. PA:QA mediated the effect of pregnancy adiposity on child fear (??=?.03, bootstrapped 95% CI 0.009, 0.07) and sadness (??=?.04, bootstrapped 95% CI 0.006, 0.08). Similar associations were observed when children were 12 and 24?months old, suggesting enduring effects. The ratio of kynurenic to quinolinic acid (KA:QA) was not associated with child negative affect. Conclusions This is the first evidence reporting that alterations in the kynurenine system during pregnancy are associated with increased child negative affectivity, an early life risk factor for psychopathology. Results further suggest that these kynurenine metabolites are a mechanistic link between pregnancy adiposity and child negative affect. Though observed effect sizes were small, results suggest that picolinic and quinolinic acid during pregnancy may be novel biomarkers for offspring behavioral risk.

Methods The study employed an incomplete batched stepped wedged cluster randomised trial design, which tests systematic replication of effects across different batches and steps and allowed schools to be recruited throughout the project. Parents (n?=?912) of children aged 4?13?years (M?=?7.91) from 160 primary schools in three Australian states were included in the evaluation. A comprehensive set of measures was administered at baseline, post-intervention and follow-up to track changes in child- and family-related outcomes. Data analysis adopted an Intention to Treat (ITT) approach, and intervention effects were estimated with Latent Growth Curve Models (LGCMs). Results ITT analyses showed significant improvements in positive parenting practices, parental adjustment and parental self-regulation, as well as reductions in coercive parenting, child anxiety symptoms, emotional maladjustment, behavioural problems and peer relationship problems with small-to-medium effect sizes. Intervention effects were systematically replicated in seven randomly assigned cohorts. Null effects were found on measures of parental relationships and child depression symptoms. Conclusions A universally offered, brief, low-intensity, school-based parenting seminar series can produce meaningful improvements in parents' reports of their parenting practices and parental self-regulation, as well as their children's social, emotional and behavioural adjustment.

Vocabulary development in autistic children: a network growth analysis / Eileen HAEBIG in Journal of Child Psychology and Psychiatry, 67-6 (June 2026)

This study compared three network growth models on their ability to account for the trajectories of expressive vocabulary acquisition in autistic and non-autistic children. Methods We studied expressive vocabularies using item-level data from a child vocabulary checklist (n?=?721 records from young autistic children; n?=?2,166 records from non-autistic toddlers). We estimated vocabulary growth trajectories for autistic and non-autistic children and assessed the goodness of fit of three models of vocabulary growth, with varying sensitivity to the structure of the environment and the learner's existing vocabulary knowledge. To do so, we first computed word-level acquisition norms that indicate the vocabulary size at which individual words tend to be learned by each group. Then we evaluated how well network growth models, based on natural language co-occurrence structure and word associations, accounted for variance in the autistic and non-autistic acquisition norms. Results Our word-level vocabulary size of acquisition norms closely aligned with age of acquisition data, indicating their utility when age of acquisition norms cannot be derived for neurodivergent populations. Furthermore, we extended key observations and demonstrated that the growth models explained similar amounts of variance in each group. Both groups are biased to learn words that have many connections to words that have been previously learned; however, even after accounting for this learning influence, autistic and non-autistic vocabulary growth trajectories receive an added boost in learning when words are connected to many other words in the learning environment, indicating a similar learning profile. Conclusions Both groups preferentially acquire new words by leveraging the semantic structure in the learning environment, indicating an overlap in theoretical accounts of vocabulary growth.

Cross-sectional and prospective relations between dysfunctional cognitive beliefs and obsessive-compulsive symptoms during late childhood and early adolescence: a test of two aetiological models / Barbara BARCACCIA in Journal of Child Psychology and Psychiatry, 67-6 (June 2026)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 67-6 (June 2026) . - p.859-868 Titre : Cross-sectional and prospective relations between dysfunctional cognitive beliefs and obsessive-compulsive symptoms during late childhood and early adolescence: a test of two aetiological models Type de document : texte imprimé Auteurs : Barbara BARCACCIA, Auteur ; Matti CERVIN, Auteur ; Davide Fausto BORRELLI, Auteur ; Giulia MIGNARRI, Auteur ; Francesco MANCINI, Auteur ; Andrea POZZA, Auteur Article en page(s) : p.859-868 Langues : Anglais (eng) Mots-clés : Obsessive-compulsive disorder  anxiety  child development Index. décimale : PER Périodiques Résumé : Background Obsessive-compulsive symptoms (OCS) often emerge during childhood and adolescence, and two aetiological models have been proposed. According to the first model, maladaptive cognitive beliefs facilitate the transformation of transient intrusive thoughts into OCS. The second model suggests that dysfunctional cognitive beliefs develop in response to increased levels of OCS. Few studies have contrasted these models, and no study has used a prospective design. Methods In this study, dysfunctional cognitive beliefs, OCS, depressive symptoms, and anxiety symptoms were measured repeatedly on three occasions during a year in a sample of 950 late-childhood children and early adolescents (Mage?=?10.80 [SD?=?1.23], 51% female). Network analysis was used to examine cross-sectional between-person associations, and a random-intercept cross-lagged panel model was used to examine prospective within-person associations. Results Cross-sectional network analyses indicated that dysfunctional cognitive beliefs were uniquely linked to OCS and significantly more strongly linked to these symptoms than to depression and anxiety. Prospective data did not support either model, but OCS and anxiety symptoms uniquely predicted each other. Sex-stratified analyses showed that dysfunctional cognitive beliefs predicted all types of symptoms at later time points in boys, while in girls, OCS and anxiety symptoms predicted each other. Assumptions of the two aetiological models of OCD were supported by cross-sectional but not prospective data. Conclusions During late childhood and early adolescence dysfunctional cognitive beliefs may play a more prominent role in the emergence of mental health symptoms in boys than in girls, but more prospective studies are needed.

The stability of the Autism Diagnostic Observation Schedule-2 in children aged 14–36 months with elevated likelihood for autism / Sarah SCHAUBROECK in Journal of Child Psychology and Psychiatry, 67-6 (June 2026)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 67-6 (June 2026) . - p.869-880 Titre : The stability of the Autism Diagnostic Observation Schedule-2 in children aged 14–36 months with elevated likelihood for autism Type de document : texte imprimé Auteurs : Sarah SCHAUBROECK, Auteur ; Ellen DEMURIE, Auteur ; Jannath BEGUM-ALI, Auteur ; Sven BÖLTE, Auteur ; Sofie BOTERBERG, Auteur ; Jan BUITELAAR, Auteur ; Tony CHARMAN, Auteur ; Terje FALCK-YTTER, Auteur ; Sabine HUNNIUS, Auteur ; Mark H.

Methods ADOS-2 assessments were conducted at 14, 24 and 36?months, with Clinical Best Estimate (CBE) autism diagnoses determined at 36?months. Results Our findings indicate that while some children have stable ADOS-2 classifications from early on, a significant proportion of the children show inconsistent classifications over time. The overall stability of ADOS-2 autism spectrum classifications increased from 14 to 36?months and agreement with CBE autism clinical diagnosis was moderate and increased with age. Conclusions Caution is warranted when interpreting individual ADOS-2 results, as they should always complement, and can never replace, a comprehensive clinical evaluation. These findings highlight the importance of continued follow-up beyond 14?months in young EL-children, a group for whom early assessment may be both feasible and beneficial and emphasises the need to integrate multiple assessment measures and multiple informants for accurate early autism identification.

Methods ADOS-2 assessments were conducted at 14, 24 and 36?months, with Clinical Best Estimate (CBE) autism diagnoses determined at 36?months. Results Our findings indicate that while some children have stable ADOS-2 classifications from early on, a significant proportion of the children show inconsistent classifications over time. The overall stability of ADOS-2 autism spectrum classifications increased from 14 to 36?months and agreement with CBE autism clinical diagnosis was moderate and increased with age. Conclusions Caution is warranted when interpreting individual ADOS-2 results, as they should always complement, and can never replace, a comprehensive clinical evaluation. These findings highlight the importance of continued follow-up beyond 14?months in young EL-children, a group for whom early assessment may be both feasible and beneficial and emphasises the need to integrate multiple assessment measures and multiple informants for accurate early autism identification.

It remains unclear whether autistic children exhibit distinct differences in intentional versus spontaneous social motor synchrony, as well as what underlying interpersonal neural synchrony (INS) mechanisms drive these potential differences. Method Fifty-four children (28 autistic) completed intentional (a delayed and synchronous imitation tasks in EX1) and spontaneous (a rhythmic hand-clapping task in EX2) tasks with an adult. Brain signals were collected by a portable multichannel fNIRS device and classified by GaussianNB machine learning approach. Results Compared with non-autistic children, autistic children showed: (1) significantly lower behavioral synchrony across both two experiments; (2) reduced activation in the right temporoparietal junction (r-TPJ, CH18) during Ex1, with no significant group differences in activation observed across all 20 fNIRS channels during Ex2; (3) significantly lower INS values in task-specific brain regions, that left inferior parietal lobule (l-IPL, CH3) in the delayed imitation condition in EX1; left inferior frontal gyrus (l-IFG, CH2), l-IPL (CH9), and r-TPJ (CH18) in the synchronous imitation condition in Ex1, and in the IPL (CH8, CH10-14) and r-TPJ (CH18) in Ex2. The GaussianNB model successfully discriminated between autistic and non-autistic children using task-related INS values, with classification accuracy varying by task condition, reaching 55.56% in the delayed imitation condition of EX1, 57.41% in the time-lag analysis condition of EX1, 64.81% in the synchronous imitation condition of EX1, and 74.07% in Ex2. Notably, the SHAP toolkit identified key channels driving group distinction?and these channels fully overlapped with the statistically significant INS channels identified in the analyses. Conclusions Autistic children exhibit differences in both intentional and spontaneous social motor synchrony, and these differences are linked to reduced INS in key social cognitive brain regions (IFG, IPL, TPJ). This research advances understanding of social functioning variations in autistic individuals and provides a foundational foundation for developing INS-based diagnostic tools.

Measurement congruence between record data and retrospective self-report measures of child maltreatment: do positive childhood experiences affect discrepancies? / Justin RUSSOTTI in Journal of Child Psychology and Psychiatry, 67-6 (June 2026)

This study addresses two primary aims: (1) to provide the first concordance estimates between prospective child protective services (CPS) records and the maltreatment and abuse chronology of exposure (MACE), a widely used retrospective CM assessment tool; and (2) to examine the influence of positive childhood experiences on discrepancies in CM assessment. Methods We utilize two maltreatment cohorts in which adults and adolescents with documented histories of CM and matched nonmaltreated controls were enrolled. Both cohorts included CM data from CPS records coded with the maltreatment classification system (MCS) and retrospective self-reports of CM and measures of positive childhood experiences. The cohorts vary in age at retrospective assessment (adults vs. adolescents), retrospective time lag (long vs. short), used different self-report measures (MACE vs. CTQ), and different methods for assessing positive experiences (explicit self-report vs. ratings of unconscious content). The rigorous dual-study design ensures findings are robust to study- and measurement-specific differences. Results Findings revealed minimal agreement between MACE self-reports and MCS-coded CPS records for maltreatment occurring from ages 0?12. Discrepancies were primarily driven by retrospective reports of CM not documented in official records. Importantly, in both studies, individuals with more positive childhood experiences were less likely to self-report maltreatment (via MACE or CTQ) that was documented based on official records. Conclusions Findings suggest that positive childhood experiences may help facilitate resilience among CM survivors by influencing memory and appraisal of childhood events. Clinical interventions that explore autobiographical memories may be particularly effective in mitigating the psychopathology sequelae of maltreatment.

However, the hypotheses regarding underlying mechanisms are inconclusive. The current study investigated the relationships of WM volume as well as WM network architecture with neurofilament light (NF-L), a marker of axonal damage. Methods Blood samples and magnetic resonance imaging scans from 77 predominantly adolescent female participants with acute AN were used. Associations of WM volume with NF-L were tested using linear models. The relationship between NF-L and alterations in brain networks was evaluated using network-based statistic (NBS) models, which predicted connectivity associated with NF-L levels. Additionally, associations with clinical variables and leptin were tested. To test the specificity of the results, control analyses were conducted on 77 female healthy participants (HC). Results We found negative associations between NF-L concentrations and WM volume. NBS analyses identified seven components, where fractional anisotropy was positively associated with NF-L. In some components, mean connectivity was negatively associated with leptin concentrations. Mediation analyses suggested that the negative correlation of leptin and NF-L might be partially mediated by changes in WM microstructure. These effects were not observed in HC. Conclusions The results suggest that WM volume reductions in acute AN might be related to axonal damage. The NBS results indicate, that the elevated fractional anisotropy previously found in AN might be related to damage processes leading to axonal swelling. All in all, the present study supports NF-L as a global blood marker for brain damage processes in acute AN.

Methods We conducted a population-based study utilizing comprehensive healthcare data. A cohort of children (N?=?516,134), born in 1998?2015 and residing in Stockholm, Sweden, was followed until they were diagnosed with anxiety, moved, or turned 18. The primary and secondary exposures were parental specified and unspecified anxiety diagnoses, respectively. The outcome was child specified anxiety diagnosis. Associations were estimated using hazard ratios (HRs) with 95% confidence intervals (CIs). Results Among exposed children, 4.3% were diagnosed with specified anxiety disorders, compared to 3.0% of unexposed (HR: 1.44, 95% CI: 1.38, 1.51). Adjustment for socioeconomic factors and other parental psychiatric disorders attenuated the risk (HR: 1.27, 95% CI: 1.21, 1.34). The risk was higher when parental anxiety was recorded in specialized psychiatric care (HR: 1.69, 95% CI: 1.60, 1.79) than in primary care (HR: 1.24, 95% CI: 1.17, 1.32). Maternal anxiety was linked to a higher risk (HR: 1.49, 95% CI: 1.41, 1.56) than paternal (HR: 1.31, 95% CI: 1.21, 1.42). Children were most likely to develop the same anxiety disorder as their parents, in cases of social anxiety, specific phobia, and panic disorder. Parental unspecified anxiety diagnoses were not associated with an increase in risk (HR: 1.02, 95% CI: 0.98, 1.07). Conclusions Parental specified anxiety modestly increased the risk of child anxiety disorders. While the overall risk was lower than previously reported, it varied across diagnosis types and care levels.

However, less is known about how exposure to excessive heat early in life may influence the development of foundational skills that shape lifelong developmental trajectories. This study examined the effects of ambient heat on early childhood development across six countries, using geographic and time-stamped data on child development and ambient temperature. Methods Our primary outcome is the Early Childhood Development Index. We used linear probability models with geographic and seasonality fixed effects to account for baseline climatic conditions, as well as other individual and contextual covariates to address potential selection bias. The sample comprised 19,607 children aged three and four from Georgia, The Gambia, Madagascar, Malawi, Sierra Leone, and the State of Palestine, all participants in Multiple Indicators Cluster Surveys collected between 2017 and 2020. We merged these data with temperature data from the ERA5-Land Monthly Aggregated Climate Dataset, calculating the mean monthly maximum temperature children experienced from birth to interview. Results We found that children exposed to average maximum temperatures above 32°C were less likely to be developmentally on track compared to those exposed to cooler temperatures, even after accounting for baseline average climatic conditions and other covariates. Domain-specific models indicate that these effects were most pronounced in literacy and numeracy skills. Subgroup analyses revealed that the negative impacts were particularly severe for children in economically disadvantaged households and urban areas, and for those lacking access to adequate water and sanitation. Conclusions This study highlights the potential impact of excessive heat on early childhood development, emphasizing the need for policies and interventions that enhance preparedness, adaptation, and resilience to support human development in an rapidly warming world.

Integrating these largely parallel bodies of research, the present study sought to explicate the associations between, and prospective predictive utility of, linguistic and neural indicators of self-focused attention in adolescents with remitted MDD over 12?months. Methods At baseline, 126 adolescents (ages 13?18) with (n?=?66) and without (n?=?60) remitted MDD completed resting-state EEG. Retrospective interviews determined the occurrence of major depressive episodes (MDEs) during the follow-up period.

Integrating these largely parallel bodies of research, the present study sought to explicate the associations between, and prospective predictive utility of, linguistic and neural indicators of self-focused attention in adolescents with remitted MDD over 12?months. Methods At baseline, 126 adolescents (ages 13?18) with (n?=?66) and without (n?=?60) remitted MDD completed resting-state EEG. Retrospective interviews determined the occurrence of major depressive episodes (MDEs) during the follow-up period. A total of ~2.3?million messages were passively acquired from adolescents' smartphones, on which the proportion of first-person singular pronouns was derived. Results During the 12?months, 29 (23.0%) participants developed an MDE (28 remitted MDD, 1 control).

This study systematically examined the network structure of reward sensitivity and its associations with depression using a network analysis framework. Methods Based on two waves of data (T1: N?=?1,136, Mage?=?14.33, 52.46% female; T2: N?=?1,083, Mage?=?14.32, 52.82% female), we constructed multiple cross-sectional and bridge networks, as well as a cross-lagged panel network model (CLPN). Results (1) Cross-sectional network analysis reveals that positive feedback serves as the core node in the depression group, while hobbies dominate in the healthy group; (2) bridging network analysis identifies hobbies and positive affect as key bridging nodes linking reward sensitivity and depression; (3) CLPN analysis demonstrates that greater engagement in hobbies at baseline significantly predicts lower levels of depression 6?months later. Conclusions This study provided a novel network perspective on the structural and temporal characteristics of reward sensitivity in depression. The findings underscored the importance of targeting specific reward types in intervention strategies and personalised mental health approaches.

Given that adolescence is a sensitive period for reward system plasticity with associated vulnerability for depression, it is important to understand developmental trajectories of different reinforcement learning parameters in normative development and in youth at risk for depression. Methods Youth aged 9?17?years completed the Play-or-Pass Iowa Gambling Task (PoP-IGT) across five timepoints. We calculated task metrics using a traditional scoring approach ? yielding summary scores for good deck play, bad deck play, and net play ? and a computational modeling approach ? yielding parameters for reward learning rate, punishment learning rate, go bias, and sensitivity to win/loss frequency ignoring outcome magnitude. We examined normative developmental trajectories for each traditional and computational performance metric using multilevel models. Further, we examined whether maternal history of depression was associated with individual differences in these trajectories. Results As hypothesized, youth showed a significant age-related increase in net play (p?=?0.003), a measure of overall good performance.

In navigating this transition, youth with disabilities encounter unique obstacles that require careful consideration and support. This study aims to identify resource profiles among youth with disabilities and their association with suicide attempts in early adulthood. Methods Using data from the National Longitudinal Study of Adolescent Health (Add Health), this study included 1,472 youth with disabilities. A Gaussian finite mixture model (GMM) was employed to identify underlying distinct groups of youth with disabilities based on their available resources. Results Four latent classes emerged: (1) Socioeconomically Advantaged and Socially Supportive (37%); (2) Socioeconomically Advantaged, but Socially Isolated (28%); (3) Socioeconomically Disadvantaged and Socially Isolated (20%); and (4) Socioeconomically Disadvantaged, but Socially Supportive (15%). Results from the generalized linear mixed model (GLMM) considering a longer transition period into adulthood up to age 32 and relevant time-varying factors found that youth in Socioeconomically Advantaged, but Socially Isolated and Socioeconomically Disadvantaged, but Socially Supportive had a significantly lower likelihood of suicide attempts compared to those in Socioeconomically Advantaged and Socially Supportive. The likelihood of suicide attempts for youth with learning disabilities was significantly lower than for those with physical disabilities, while a history of suicide attempts in adolescence and experience with a death by suicide of family members or friends increased the odds of suicide attempts. Conclusions The study highlights the heterogeneity of youth with disabilities, demonstrating how demographic characteristics, disability-specific needs, family and school environments and social support systems intersect to influence suicide attempt prevention.

The nature and nurture of primary and secondary callous–unemotional traits: evidence from two independent twin samples / Rachel C. TOMLINSON in Journal of Child Psychology and Psychiatry, 67-6 (June 2026)

However, the etiology of CU traits may be heterogeneous, undermining the search for effective treatments. The level of co-occurring anxiety has been used to identify ?primary? (lower anxiety) versus ?secondary? (higher anxiety) variants of CU traits. The primary variant has been hypothesized to emerge from strong genetic influence and secondary variants as an adaptation to adversity, such as exposure to childhood maltreatment. However, little research has tested this hypothesis directly. Methods We examined whether anxiety moderates the etiology of CU traits to determine whether this phenotypic feature can help distinguish CU traits with stronger genetic or environmental risk. In two population-based twin cohorts (initial sample: N?=?1,196, aged 6?11, oversampled for exposure to neighborhood disadvantage; follow-up sample: N?=?13,486, age 7), we used genotype-by-environment interaction twin modeling to examine if parent-reported child anxiety moderated the etiology of concurrent parent-reported child CU traits. Results Anxiety moderated the etiology of CU traits across both samples, such that nonshared environmental influences increased as anxiety increased. Additionally, in the larger sample, genetic influences decreased with increasing anxiety. Conclusions These findings support theories suggesting that co-occurring anxiety may distinguish CU traits with different origins: CU traits with higher anxiety appear more influenced by nonshared environmental factors?potentially including adversity?and may show weaker genetic influence. Assessing for co-occurring child anxiety is likely important for diagnosing and personalizing treatments among children with CU traits.

Analyzing direct and indirect genetic effects on early neurodevelopmental traits – a commentary on Hegemann et al / Yalan LI in Journal of Child Psychology and Psychiatry, 67-6 (June 2026)

Findings reveal that indirect genetic effects are particularly pronounced for hyperactivity and restricted and repetitive behaviors, while direct effects dominate in language and motor development. Notably, associations between parental cognitive and educational attainment polygenic scores and child outcomes suggest potential protective genetic influences. However, several methodological considerations may affect interpretation. Excluding closely related individuals could limit the detection of extended familial effects, and reliance on polygenic scores derived from predominantly European GWAS may constrain generalizability. Furthermore, current PGS explain only a portion of trait heritability, possibly underrepresenting true genetic contributions. Future studies incorporating extended family structures, diverse populations, and alternative methods to model gene?environment interplay are essential for refining insights into early neurodevelopmental processes.
