Young people with neurodevelopmental disorders, such as attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), show high rates of mental health problems, of which depression is one of the most common. Given that depression in ASD and ADHD is linked with a range of poor outcomes, knowledge of how clinicians should assess, identify and treat depression in the context of these

Relative age within the school year (‘relative age’) is associated with increased rates of symptoms and diagnoses of mental health disorders, including ADHD. We aimed to investigate how relative age influences mental health and behaviour before, during and after school (age range: 4–25 years).

Early differences in sensorimotor functioning have been documented in young autistic children and infants who are later diagnosed with autism. Previous research has demonstrated that autistic toddlers exhibit more frequent head movement when viewing dynamic audiovisual stimuli, compared to neurotypical toddlers. To further explore this behavioral characteristic, in this study, computer vision (CV)

Very few predictive models in Psychiatry had their performance validated in independent external samples. A previously developed multivariable demographic model for attention-deficit/hyperactivity disorder (ADHD) accurately predicted young adulthood ADHD using clinical and demographical information collected in childhood in three samples from developed countries, but failed to replicate its performance

There is growing evidence for the role of circadian factors in adolescents' sleep and academic adjustment, with greater evening preference being linked to poorer academic functioning. However, studies have yet to evaluate this association prospectively in adolescence, nor have studies examined daytime sleepiness as a putative mechanism linking evening preference to poor academic functioning. The current

The deleterious developmental effects of exposure to early adversity have been well documented in the scientific literature. The finding that poverty in early childhood is among the most robust predictors of a range of poor developmental outcomes has been well known for decades. More recently, evidence that early experiences of poverty and related forms of adversity negatively impact the function and

Understanding complex influences on mental health problems in young people is needed to inform early prevention strategies. Both genetic and environmental factors are known to influence youth mental health, but a more comprehensive picture of their interplay, including wide-ranging environmental exposures – that is, the exposome – is needed. We perform an integrative analysis of genomic and exposomic

Daily skin-to-skin contact (SSC) during early infancy fosters the long-term development of children born preterm. This is the first randomized controlled trial assessing the potential beneficial effects of daily SSC on executive functioning and socio-emotional behavior of children born full-term. Whether children of mothers who experienced prenatal stress and anxiety benefitted more from SSC was also

BACKGROUND Cognitive therapy for SAD (CT-SAD) is a first-line recommended treatment for adult social anxiety disorder (SAD) and shows considerable promise for youth. However, the high prevalence of adolescent SAD and limited number of therapists presents an implementation challenge. Delivery of CT-SAD via the Internet may offer part of the solution. METHOD Forty-three youth (14-18 years) with SAD recruited

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

5%–10% children and young people (CYP) experience specific phobias that impact daily functioning. Cognitive Behaviour Therapy (CBT) is recommended but has limitations. One Session Treatment (OST), a briefer alternative incorporating CBT principles, has demonstrated efficacy. The Alleviating Specific Phobias Experienced by Children Trial (ASPECT) investigated the non-inferiority of OST compared to multi-session

The number of children and young people referred to community eating disorders services escalated dramatically shortly after onset of the Covid-19 pandemic. Many presented with medical instability following restrictive eating and needed acute hospitalisation to correct malnutrition. In addition to the many risk factors for mental health problems that young people have been subjected to since onset

Cross-sectional studies have demonstrated associations between screen time and disruptive behavior disorders (conduct disorder and oppositional defiant disorder); however, prospective associations remain unknown. This study's objective was to determine the prospective associations of contemporary screen time modalities with conduct and oppositional defiant disorder in a national cohort of 9–11-year-old

The world has experienced an unprecedented mental health crisis associated with the COVID-19 pandemic (Liu et al., 2020). After more than two years navigating the associated uncertainty and distress, the impact on youth mental health continues to be a pressing concern. Those in the mental health field, as well as the children and families plagued by its impact, are inundated with seeing firsthand the

South Africa's rates of psychiatric morbidity are among the highest in sub-Saharan Africa and are foregrounded by the country's long history of political violence during apartheid. Growing evidence suggests that in utero stress exposure is a potent developmental risk factor for future mental illness risk, yet the extent to which the psychiatric effects of prenatal stress impact the next generation

Neonatal risk factors, such as preterm birth and low birth weight, have been robustly linked to neurodevelopmental deficits, yet it is still unclear why some infants born preterm and/or low birth weight experience neurodevelopmental difficulties while others do not. The current study investigated this heterogeneity in neurodevelopmental abilities by examining additional neonatal morbidities as risk

Parenting interventions in humanitarian settings have prioritized the acquisition of parenting knowledge and skills, while overlooking the adverse effects of stress and distress on parenting—a key mediator of refugee children's mental health. We evaluated the effectiveness of the Caregiver Support Intervention (CSI), which emphasizes caregiver wellbeing together with training in positive parenting

Chaotic home environments may contribute to children's attention-deficit hyperactivity disorder (ADHD) symptoms. However, ADHD genetic risk may also influence household chaos. This study investigated whether children in chaotic households had more ADHD symptoms, if mothers and children with higher ADHD genetic risk lived in more chaotic households, and the joint association of genetic risk and household

Preschoolers' temperament characteristics are associated with children's long-term development. Such links underscore the importance of understanding factors that shape temperament during preschool. This is the first study to examine genetic and environmental sources of developmental growth in three temperament dimensions: surgency, negative affectivity, and effortful control, during the preschool

It has been suggested that the sequelae of trauma are under-recognized in youth on the autism spectrum. We aimed to generate expert consensus regarding important trauma indicators, including but not limited to traumatic stress symptoms, in autistic youth.

Poor sleep and anxiety disorders are highly comorbid in youth, and each predicts altered ventral striatum (VS) response to rewards, which may impact mental health risk. Contrasting evidence suggests previously reported negative associations between sleep health and VS response may be stronger or weaker in youth with anxiety, indicating sensitivity to win/loss information or blunted reward processing

Bayesian statistical approaches offer nuanced, detailed, and intuitive analyses, even with small sample sizes. Although these qualities are highly relevant for researchers in child and adolescent mental health, Bayesian methods are still quite rarely employed. This editorial perspective will briefly describe what is different about Bayesian statistical methods, discuss some of the ways they may benefit

Whilst genetic and environmental risk factors for schizophrenia (SCZ) and major depressive disorder (MDD) have been established, it is unclear whether exposure to environmental risk factors is genetically confounded by passive, evocative or active gene–environment correlation (rGE).

Children with ADHD tend to achieve less than their peers in school. It is unknown whether schools moderate this association. Nonrandom selection of children into schools related to variations in their ADHD risk poses a methodological problem.

In Pacheco et al. (2022), the citations for the following statement should have included NIH Office of Portfolio Analysis (2016) and Hoppe et al. (2019). It should be: We used a machine learning approach called word2vec (Hoppe et al., 2019; Mikolov, Chen, Corrado, & Dean, 2013; NIH Office of Portfolio Analysis, 2016), which learns word relationships based on the title, abstract, and specific aims of

Identifying proximal risk factors for suicidal ideation that are modifiable and relevant for adolescents and young adults is critical for suicide prevention. This study used an intensive monitoring approach to examine whether objectively- and subjectively- measured sleep characteristics predict next-day suicidal ideation occurrence and intensity through affective reactivity to interpersonal events

Theoretical models of the development of childhood externalizing disorders emphasize the role of parents. Empirical studies have not been able to identify specific aspects of parental behaviors explaining a considerable proportion of the observed individual differences in externalizing problems. The problem is complicated by the contribution of genetic factors to externalizing problems, as parents

Diagnostic assessment of ASD requires substantial clinical experience and is particularly difficult in the context of other disorders with behavioral symptoms in the domain of social interaction and communication. Observation measures such as the Autism Diagnostic Observation Schedule (ADOS) do not take into account such co-occurring disorders.

The lockdowns during the COVID-19 pandemic had and continue to have severe and wide-ranging effects worldwide on mental health and loneliness. In this commentary, I summarise Houghton et al. (2022) who explored these effects longitudinally in adolescents in Western Australia, with and without a Neurodevelopmental Disorder (NDD), considering the strengths and weaknesses of the article and its importance

This paper addresses the hypothesis that autism spectrum disorder features follow multiple long-term developmental trajectories, including an absence of symptoms that were present in childhood, by the time of adolescence. In early work on this topic, this circumstance was called an ‘optimal outcome’. To better reflect the reality of multiple excellent outcomes regardless of whether autism spectrum

Genetic and environmental influences on externalizing problems are often studied separately. Here, we extended prior work by investigating the implications of gene–environment interplay in childhood for early adult externalizing behavior. Genetic nurture would be indicated if parents' genetic predisposition for externalizing behavior operates through the family environment in predicting offspring early

Suicidal thoughts and behaviors (STB) constitute a central public health concern in adolescence. Previous studies emphasized the difficulty to cope with negative life events during adolescence as a risk factor for STB. Familial and genetic liability has also been documented to explain STB risk. Nevertheless, less is known about aggregate genetic liability and its possible interaction with negative

The commentary cites a study by Li and colleagues (2022) that conducted a comprehensive study of depression and anxiety symptoms among college students worldwide. We highlight the valuable contribution of this work to ongoing research, policy, and practice related to the early diagnosis and prevention of depression and anxiety symptoms in college students. The comprehensive report compensates for the

Early detection is critical for easing the rising burden of psychiatric disorders. However, the specificity of psychopathological measurements and genetic predictors is unclear among youth.

Maladaptive family environments harm child development and are passed across generations. Childhood interventions may break this intergenerational cycle by improving the family environments children form as adults. The present study investigates this hypothesis by examining follow-up data collected 18 years after the end of the childhood Fast Track intervention designed to prevent externalizing problems

Peer connections in school classrooms play an important role in social–emotional development and mental health. However, research on the association between children's peer relationships and white matter connections in the brain is scarce. We studied associations between peer relationships in the classroom and white matter structural connectivity in a pediatric population-based sample.

There are profound consequences when developing youth do not get adequate sleep. Adolescents who experience poor sleep may be more likely to engage in offending behavior. While there is a documented association between the number of hours youth sleep and their likelihood of offending, it is unclear how youths' perceptions of their sleep quality contribute to offending. Further, scholars have yet to

Transdiagnostic is arguably one of the most ‘in vogue’ terms at the moment in child and adolescent psychiatry. A search for the word ‘transdiagnostic’ in PubMed shows an exponential increase over the last decade in medical research, with 2021 showing the highest ever use of this word. Within child and adolescent psychiatry, there are many reasons this word might be used. Conditions within child and

Social attention affords learning opportunities across development and may contribute to individual differences in developmental trajectories, such as between male and female individuals, and in neurodevelopmental conditions, such as autism.

Prior research suggests that symptoms of attention deficit hyperactivity disorder (ADHD) and related neurodevelopmental disorders may derive from alterations in the brain's ability to flexibly tune the balance between information integration and segregation and global versus local processing. This balance allows the brain to optimally filter salient stimuli in the environment and can be measured with

In this issue of Journal of Child Psychology and Psychiatry, many interesting research findings converge to suggest that prevention and early intervention strategies can be the key to building healthier societies with happier people. Across different societies, we observe that scientific attention and practice is becoming more evenly divided between the traditionally dominant focus on clinical disorders

Computational research had determined that adults with obsessive–compulsive disorder (OCD) display heightened action updating in response to noise in the environment and neglect metacognitive information (such as confidence) when making decisions. These features are proposed to underlie patients’ compulsions despite the knowledge they are irrational. Nonetheless, it is unclear whether this extends

Exposure to community violence is common worldwide and is associated with emotional and behavioural problems in children. Little is known about sources of resilience. Building on our previous work on the contribution of callous-unemotional (CU) traits to child aggression in Colombia, we examined whether positive parenting is protective for children whose families are exposed to community violence.

The role of positive maternal mental health during pregnancy in child mental health remains largely unknown. We investigated whether positive maternal mental health during pregnancy is associated with lower hazards of mental and behavioral disorders in children and mitigates the adverse effects of negative maternal mental health.

Self-Harm Significantly Higher in Populations with ADHD, Anxiety, ASD, Depression, and Eating Disorders. I appreciated your recent paper on the large and well-matched studies on nonfatal self-harm and suicide among adolescents in the UK Clinical Practice Research Datalink (Cybulski et al. 2021). This large study involved 56,008 self-harm cases and 1,399,356 controls aged 10–19 years and reported that

Prior to the pandemic, we already had good reason to be concerned about the mental health of children and young people. As an example, the 2017 Mental Health of Children and Young People (MHCYP) survey in England, comprising a large, national probability sample, identified that one in nine children had a probable mental health disorder, with a 49% increase in emotional disorders compared to a previous

Previous research has suggested that children with attention-deficit/hyperactivity disorder (ADHD) symptoms commonly show emotion dysregulation difficulties. These difficulties may partly explain the strong tendency for internalizing problems such as anxiety and depression to co-occur with ADHD symptoms. However, no study has yet provided a longitudinal analysis of the within-person links between ADHD

Malfunctioning of executive functions correlates with psychopathology in children. However, the directionality, the extent to which the relation varies for various disorders, and whether prospective relations afford causal interpretations are not known.

Effective antibullying interventions may reduce the impact of bullying on young people’s mental health. Nevertheless, little is known about their effectiveness in reducing internalizing symptoms such as anxiety or depression, and what factors may influence intervention effects. The aim of this systematic review, meta-analysis, and metaregression is to assess the effects of school-based antibullying

In this Editorial Perspective, we take a systematic look at the overall nature of the Covid-19 related research on mental health in children and young people, to gain insight into the major trends in this area of research and inform future lines of investigation, clinical practices, and policies. By means of state-of-the-art scientometric approaches, we identified 3,692 relevant research outputs, mainly

The experience of two or more mental health disorders or symptom-clusters, either simultaneously or sequentially, is common among adults. Increasing evidence suggests that such comorbidity may also be prevalent among children though it often extends beyond mental health disorders. This is highlighted by several of the papers featured in the current issue of the Journal, which are summarised in this

Children who are maltreated show deficits in emotion recognition, expression, and understanding. The goal of the current meta-analysis was to determine the degree to which maltreatment is associated with deficits in the ability to recognize one’s own emotions – a phenomenon known as alexithymia. Alexithymia may be a mechanism explaining the association between childhood maltreatment and various psychological

Williams syndrome (WS) is a rare genetic disorder caused by a microdeletion at the 7q11.23 region and is characterized by diverse symptoms encompassing physical and cognitive features. WS was reported to be associated to altered DNA methylation (DNAm) patterns. However, due to the limited information from long-term studies, it remains unclear whether WS accelerates aging. Genome-wide DNAm profiles

Previous longitudinal studies have demonstrated that psychosocial outcomes for autistic adults are very limited. However, most studies are clinic-based and liable to selection bias and major methodological problems.

Peer problems have emerged as important predictors of Non-Suicidal Self-Injury (NSSI) development during adolescence. However, the possibility that adolescents who engage in NSSI may, in turn, be at increased risk for experiencing difficulties with their peers has rarely been examined. This study investigated the reciprocal associations between peer problems (e.g. peer victimization, friendship stress
