Background: The present study sought to extend the existing knowledge on the relationship between risky behavior and ADHD by studying transactions between these two variables within participants and across various time scales.

Methods: Participants were 281 adolescents (170 girls), age 13-18 years old (M = 14.8, SD = 1.3), and 1 of their parents. Risky behavior and ADHD symptoms measurements were taken at varying time intervals: annually, 4-monthly, and weekly. Random Intercepts Cross-Lagged panel modeling (RI-CLPM) was used to examine longitudinal bidirectional associations between risky behavior and ADHD symptoms.

Results: At the between-person level, positive associations between risky behavior and ADHD symptoms were found in all time scales. At the within-person level, according to adolescents' reports, ADHD symptoms did not predict subsequent fluctuations in adolescents' risky behavior, though according to parental reports on adolescents' risky behaviors, a cross-lagged effect of risky behaviors on ADHD symptoms was evident in the annual time scale.

Conclusions: Between-person relations between ADHD and risky behavior were established, suggesting an underlying common factor. Within-person relations were suggested only in parent reports and specific time scales. Our research underscores the critical need to differentiate between inter-individual and intra-individual effects when investigating the interplay between ADHD and risky behavior over time.

Background: Exposure to trauma in childhood is associated with an increased risk for internalising symptoms. Alterations in pubertal development has been proposed as a potential mechanism underpinning this association. However, longitudinal studies, which are needed to examine pubertal development over time, are scarce. The goal of this pre-registered study was to examine how trauma exposure shapes the timing and tempo of pubertal development, and in turn contributes to risk for internalising symptoms in female youth.

Methods: Using the largest longitudinal sample to date, we characterised profiles of pubertal development across four time points in female youth from the Adolescent Brain Cognitive Development (ABCD) Study (N = 4,225, age range = 9-14 years) using latent profile analysis. Pubertal development was assessed using the Pubertal Development Scale (at four time points). Trauma exposure was quantified using the post-traumatic stress disorder subscale from the parent-report Kiddie Schedule for Affective Disorders and Schizophrenia for DSM-5 (at baseline), and internalising symptoms were assessed using the self-report Brief Problem Monitor (at 3-year follow-up).

Results: Pubertal development could be grouped into three latent classes: early starters (9% of sample), typical developers (76%) and slow developers (15%). The early starters demonstrated higher levels of trauma exposure compared to typical developers and slow developers, while slow developers showed the least exposure to trauma. Youth with greater exposure to trauma were at an increased risk for internalising symptoms at ages 12-14 years, and this association was mediated by a higher pubertal status at ages 9-10 years, but not by a faster pubertal tempo.

Conclusions: Accelerated pubertal development, characterised by an earlier age of onset but not a higher pubertal tempo in the transition from late childhood to early adolescence, may be a mechanism through which trauma exposure in childhood increases risk for internalising symptoms in female youth.

Background: Infants vary significantly in the way they process and respond to sensory stimuli, and altered sensory processing has been reported among infants later diagnosed with autism. Previous work with adolescents and adults suggests that variability in sensory processing may have a strong genetic basis. Yet, little is known about the etiological factors influencing sensory differences in infancy, when brain circuits supporting social and non-social cognition are sculpted and learning about the world via sensory input largely occurs in interaction with caregivers.

Methods: We analysed data from a community sample of monozygotic (MZ) and dizygotic (DZ) 5-month-old same-sex twins (n = 285 pairs, n = 158 MZ pairs, n = 150 male pairs) from the BabyTwins Study in Sweden (BATSS) using exploratory factor analysis, generalised estimating equations and multivariate twin models to delineate the phenotypic and etiological structure of individual variability across different sensory processing dimensions, as measured by the Infant/Toddler Sensory Profile. Developmental links to later autistic traits were also assessed, as measured by total scores from the Quantitative Checklist for Autism in Toddlers at 36 months.

Results: Results suggested separability between sensory processing dimensions (i.e. sensation seeking, sensation avoiding, sensory sensitivity and low registration) at a phenotypic and etiological level, with significant contributions from additive genetics and family environment that were unique to each sensory dimension and significant but smaller contributions from shared influences. Sensory domains also showed etiological separability, with unique genetic influences to each domain, while contributions from shared environment were in part shared across domains. A higher incidence of tactile-related behaviours and behaviours associated with sensory sensitivity, sensation avoiding, and low registration were significantly associated with higher levels of autistic traits in toddlerhood.

Conclusions: This study provides a map of the phenotypic and etiological structure of sensory processing in infancy, which will be informative for studies of both typical and atypical development.

Blader et al.'s (2025) recent annual review article makes an important contribution to the literature on emotion dysregulation in child and adolescent mental health. In addition to synthesizing the current evidence base, the authors put forth a cogent formalized view of emotion regulatory processes and how they go awry. Much has been written on emotion (dys)regulation and psychopathology (for overviews, see Lincoln et al., 2022; Paulus et al., 2021; Sheppes et al., 2015). It would therefore be reasonable to ask what novel contribution could be made by a new review article at this time. But for all that has been written, there is much work still to be done. Blader et al. (2025) admirably rise to meet this challenge. We hope this commentary amplifies and adds to their effort. Below, we reflect on a few aspects of their contribution and offer some further thoughts that may inform future work in this area.

Background: Autistic individuals often receive psychiatric diagnoses prior to their autism diagnosis. It remains unclear to what extent autistic females and males differ in their likelihood of receiving psychiatric diagnoses prior to their autism diagnosis and continue seeking care for them after an autism diagnosis.

Methods: In a nationwide cohort of all individuals born in Sweden 1990-2015 with a clinical autism diagnosis (N = 72,331, n_females = 24,110), we used linear and logistic regression to estimate the association between sex and (a) psychiatric diagnoses before autism diagnosis, including time trends by autism diagnosis year (2010-2020), (b) autism diagnosis age in those with preceding diagnoses, (c) stability of preceding diagnoses (defined as continued care utilization indicated through diagnosis or medication in the 5 years following autism diagnosis).

Results: In total 54.2% of autistic females and 40.9% of autistic males received at least one preceding psychiatric diagnosis (most common: ADHD, anxiety, depression). Autistic females showed higher odds than males for most preceding psychiatric diagnoses (OR_range = 1.29 [1.18, 1.41]-10.69 [8.06, 14.17]), except psychotic disorders (OR = 0.91 [0.78, 1.06]) and ADHD (OR = 0.69 [0.66, 0.71]). Sex differences in preceding diagnoses were persistent across different autism diagnosis years (2010-2020). For most conditions, females with a preceding diagnosis were diagnosed with autism later than males with the same condition. For both sexes, the stability of preceding diagnoses varied considerably (23.1%-88.9%) and was less than 50% for most diagnoses. Females showed a higher stability for anxiety, sleep disorders and self-harm (OR_range = 1.45 [1.30, 1.62]-2.37 [1.93, 2.90]), and males for psychotic disorders (OR = 0.60 [0.44, 0.81]).

Conclusions: Autistic females are more likely to be diagnosed with psychiatric conditions prior to an autism diagnosis and receive care for them post autism diagnosis. Our findings emphasize the variability of clinical presentation and importance of disentangling persistent support needs from overlapping diagnostic presentations, particularly in autistic females, to provide appropriate and timely care.

The spectrum of psychosis is highly relevant to child and adolescent mental health. Psychotic symptoms are common in children and adolescents. The onset of psychotic disorders is often preceded by neurodevelopmental problems in early childhood, and some 13% of adolescents attending specialist mental health services will later be diagnosed with a psychotic disorder or bipolar disorder. Although 12% of psychotic disorders and 8% of schizophrenia cases have onset prior to age 18, there is little evidence available to guide the clinical care of young people with early onset psychosis. This commentary summarises the key findings of the annual research review on Psychosis in Children and Adolescents. It highlights the urgent need for clinicians and researchers in child and adolescent mental health to contribute to finding solutions to prevent the onset of psychosis and improve the lives of young people with early onset psychosis and their families.

Background: Certain temperament characteristics, such as low effortful control and high negative affectivity, are linked to an elevated likelihood for later psychopathology. Although genetic vulnerability has been associated with a number of psychiatric conditions, little work has examined the genetic architecture underlying temperament or the genetic overlap between early temperament profiles and later mental health outcomes. The present study examined associations of polygenic scores for anxiety (PGS-Anxiety) and ADHD (PGS-ADHD) with temperament characteristics in a longitudinal sample of children assessed from infancy through age 7 years.

Methods: Analyses were conducted in a sample of children (European Ancestry n = 476; Full Sample [European and other ancestries] N = 606).

Results: We observed an age-by-PGS interaction on effortful control. As children aged, there appeared to be stronger negative associations between PGS-ADHD and effortful control. No associations were observed between PGS-Anxiety and negative affectivity.

Conclusions: Overall, the findings suggest some support for associations between genetic underpinnings for externalizing psychopathology and temperament that increase over time.

Background: Dyslexia is one of the most common neurodevelopmental disorders. There have been many definitions over the past century, and debate continues as to how dyslexia should be defined. This debate contributes to confusion and misinformation. We move beyond the debate by establishing areas of consensus among a wide range of experts.

Methods: We conducted a Delphi study with a panel of dyslexia experts, including academics, specialist teachers, educational psychologists, and individuals with dyslexia, asking them for their views on a set of key statements about dyslexia. We carried out two survey rounds, in each case accepting statements with greater than 80% consensus and reviewing and revising other statements using feedback from the expert panel. This was followed by discussion with a subset of the panel around a few statements with marginal consensus.

Results: Forty-two statements were ultimately accepted. In the current paper we review those statements that pertain to a definition of dyslexia, demonstrate how they align with the research literature, and build on previous definitions of dyslexia.

Conclusions: There was considerable consensus in our expert panel that dyslexia is a difficulty in reading and spelling, associated with multiple factors, and that it frequently co-occurs with other developmental disorders. It was agreed that difficulties in reading fluency and spelling are key markers of dyslexia across different ages and languages. We conclude with a proposed new definition of dyslexia.

It was early 2020, a week or two into Hilary Term, what everyone else calls Spring Term, but we at Oxford love our arcane traditions. I recall one of my graduate students, from China, coming to me ashen-faced at the end one of my lectures on the effects of bilingualism on the linguistic and cognitive development of young learners. “Please be careful,” she said. “Have you heard about the disease. It's really scary. Please look after your family.” Over the preceding Christmas break, news had started to filter through about a new form of flu that had spread rapidly from Wuhan in Eastern China to other parts of the country and was now starting to emerge in other parts of the world. We were starting to see desperate images of enforced quarantine, coerced separation of infected individuals from their loved ones, the rapid construction of temporary hospitals to house the unwell, and of course, school closures. It didn't look good. But I had seen similar outbreaks in the past. I had been working in Southeast Asia during the avian flu epidemic of 2003–04, and I was still there when swine flu broke out in 2009. Both were worrying, but neither had come to anything that could be classified as universally threatening. The school where I worked sent colleagues and children to be tested at the first sign of a tickly throat or stuffy nose, and a strict and regular cleaning and hand sanitising regime was implemented.

Jaffee and colleagues present a masterful review of the evidence for the impacts of cash transfer programmes on child and adolescent mental health in the United States. While global meta-analyses find evidence of effectiveness, Jaffee and colleagues highlight the limited number of studies in Northern America, but find overall results indicating small but meaningful effect sizes on improving emotional and behavioural health, and greatest impacts for the poorest families.
