Article Synopsis
  • Childhood callous-unemotional (CU) traits are linked to high reward sensitivity and low punishment sensitivity, potentially increasing the risk of substance misuse in adolescents.
  • The study analyzed data from the UK Millennium Cohort to explore how reward and punishment sensitivity influence the relationship between CU traits and substance use, specifically looking at alcohol, cannabis, and illicit drugs at age 17.
  • Results indicate that while CU traits alone did not predict substance use when accounting for various factors, increased reward sensitivity contributed to higher substance use, suggesting that interventions for at-risk adolescents should focus on tailored strategies for those with CU traits and specific neurocognitive profiles.

Background And Aims: Peer interaction difficulties are often elevated amongst children with language disorders, yet the mechanisms underlying these difficulties are unclear. Previous research indicates that poor conflict management, social withdrawal, emotion regulation difficulties, and reduced prosocial behavior may contribute to peer interaction difficulties. However, this research often uses adult perspectives, failing to acknowledge child perceptions of these experiences.

Many children with developmental language disorder (DLD) have emotion recognition and regulation difficulties, but there are currently no known interventions enhancing emotional awareness in this population. This study explores the impact of parents' perspectives regarding children with DLD emotional understanding through a parent-led online emotion recognition (ER) intervention. Ten parents of children with DLD aged 6-11 participated in the study.

Current methods used to investigate emotional inference and conflict resolution knowledge are limited in their suitability for use with children with language disorders due to a reliance on language processing. This is problematic, as nearly 8% of the population are estimated to have developmental language disorder (DLD). In this paper, we present 'Zoti's Social Toolkit', a set of animated scenarios that can be used to assess emotion inferencing and conflict resolution knowledge.

Callous-unemotional (CU) traits are characterized by a lack of guilt and empathy, restricted affect, and low concern about performance, and are increasingly recognized as co-occurring with substance use in youth. However, there is mixed evidence concerning whether they make a unique contribution to substance use. This systematic review and meta-analysis sought to quantify the association between CU traits and substance use in childhood, accounting for potential moderators including sample characteristics (age, gender, community versus clinical/forensic samples), CU traits measure and informant, and study design (cross-sectional or longitudinal).

Bifactor models are increasingly being utilized to study latent constructs such as psychopathology and cognition, which change over the lifespan. Although longitudinal measurement invariance (MI) testing helps ensure valid interpretation of change in a construct over time, this is rarely and inconsistently performed in bifactor models. Our review of MI simulation literature revealed that only one study assessed MI in bifactor models under limited conditions.

Children with Developmental Language Disorder (DLD) often experience co-occurring psychosocial difficulties, the developmental trajectories of which are still not fully understood. This study sought to explore the manifestation of such difficulties during childhood, through first-hand accounts of those with DLD and their close relatives. Individual semi-structured interviews were conducted with 11 mothers of children with DLD (aged 6-12 years old) and were analysed alongside the secondary data from interviews of five adults with DLD.

Background: It is well-documented that children with Developmental Language Disorder (DLD) have a higher likelihood of experiencing anxiety, as well as other socio-emotional and behavioural (SEB) difficulties. Despite this, there is little consensus as to how these difficulties manifest. This study aims to understand the prevalence of broader SEB difficulties and anxiety, informing intervention development by understanding the relationships between them.

Social cognition impairments may explain social, emotional and behavioural difficulties (SEBD) in individuals with Developmental Language Disorder (DLD). In a novel approach, the Social Attribution Task (SAT) was used to examine this association. SAT narratives were coded from 53 participants [n = 26 DLD; n = 27 typical language development (TLD)] matched on age (M = 13;6) and gender (35.

Article Synopsis
  • Researchers identified three distinct groups of depressed adolescents based on symptom patterns: Severe, Moderate, and Somatic, which differed in symptom severity and functional impairment.
  • The study analyzed data from 454 adolescents, revealing that those in the Severe and Moderate classes experienced significant treatment-related symptom reductions, while the Somatic group did not show similar improvements.
  • Findings suggest that high levels of somatic symptoms may indicate a lower likelihood of benefiting from psychological treatments, regardless of overall severity or functional impairment.

Adolescents with Developmental Language Disorder (DLD) are at risk for increased feelings of anxiety and depression compared to their typically developing (TD) peers. However, the underlying pathways involved in this relationship are unclear. In this initial study of the 'social mediation hypothesis', we examine social functioning as a mediator of emotional problems in a cross-sectional sample of adolescents with DLD and age- and sex-matched controls.

Purpose Adolescents with a history of language difficulties are at risk for increased social and emotional difficulties; however, the pathways involved are unclear. We examine the contribution of poor emotion regulation by comparing longitudinal data from children at risk of developmental language disorder (rDLD) and the general population. Method Data from the Millennium Cohort Study were analyzed at ages 3, 5, 7, 11, and 14 years.

Longitudinal research into the development of prosociality during childhood contributes to our understanding of individual differences in social and emotional outcomes. There is a dearth of literature on the development of prosociality in children with Developmental Language Disorder (DLD). Data from the UK based Millennium Cohort Study was used to investigate prosociality from age 5 to 11 years in 738 children at risk of Developmental Language Disorder (r-DLD) and 12,972 children in a general population (GP) comparison group.

Children and adolescents with delayed or disordered language development are at increased risk of a number of negative outcomes, including social and emotional problems and mental health difficulties. Yet, in low- and middle- income countries, where risk factors for compromised language development are known to be prevalent, there is a lack of research on the association between child and adolescent language ability and mental health outcomes. This study evaluates data from a cross-sectional study in Khayelitsha, a semi-urban impoverished community near Cape Town, South Africa.

Although familial adversity is associated with poorer outcomes in childhood and adulthood, little research has looked at the influence of stability or transition between distinct familial adversity subgroups or the impact in adolescence. Using data from the 9-month, 3-, 5-, and 14-year time waves of the Millennium Cohort Study (n > 18,000), we used latent class analysis to identify distinct classes of early familial adversity (marital instability/conflict, "suboptimal" parenting, economic disadvantage, and parental mental health problems) and the impact of these adversity classes on adolescent (a) mental health (including self-harm), (b) risk taking, (c) criminality, and (d) victimization. Four profiles were identified largely differing on economic hardship, family composition, and parental conflict.

Numerous studies suggest an association between language and executive function (EF), but evidence of a developmental relationship remains inconclusive. Data were collected from 75 deaf/hard-of-hearing (DHH) children and 82 hearing age-matched controls. Children were 6-11 years old at first time of testing and completed a battery of nonverbal EF tasks and a test of expressive vocabulary.

The significant mental health needs of young people in out-of-home care has been well-documented. However, there is little empirical evidence on the timing or development of these difficulties, once these young people have been removed from the maltreatment-environment. Such information may provide useful clinical insight in to how problems develop and persist and whether intervention timings may allow for the prevention of later mental health problems.

Little is known about the underlying relationships between self-reported mental health items measuring both positive and negative emotional and behavioural symptoms at the population level in young people. Improved measurement of the full range of mental well-being and mental illness may aid in understanding the aetiological substrates underlying the development of both mental wellness as well as specific psychiatric diagnoses. A general population sample aged 14 to 24 years completed self-report questionnaires on anxiety, depression, psychotic-like symptoms, obsessionality and well-being.

Background: Early life stress (ELS) consists of child family adversities (CFA: negative experiences that happened within the family environment) and/or peer bullying. ELS plays an important role in the development of adolescent depressive symptoms and clinical disorders. Identifying factors that may reduce depressive symptoms in adolescents with ELS may have important public mental health implications.

Background: UK service structure necessitates a transition out of youth services at a time of increased risk for the development and onset of mental disorders. Little is currently known about the mental health and psychosocial outcomes of leaving services at this time. The aim of this study was to determine predictors of mental health and social adjustment in adolescents leaving mental health or social care services.
