Norbury, Courtenay Frazier; Vamvakas, George; Gooch, Debbie; Baird, Gillian; Charman, Tony; Simonoff, Emily; Pickles, Andrew – Journal of Child Psychology and Psychiatry, 2017
Background: Language development has been characterised by significant individual stability from school entry. However, the extent to which trajectories of language growth vary in children with language disorder as a function of co-occurring developmental challenges is a question of theoretical import, with implications for service provision.…

Norbury, Courtenay Frazier; Gooch, Debbie; Wray, Charlotte; Baird, Gillian; Charman, Tony; Simonoff, Emily; Vamvakas, George; Pickles, Andrew – Journal of Child Psychology and Psychiatry, 2016
Background: Diagnosis of "specific" language impairment traditionally required nonverbal IQ to be within normal limits, often resulting in restricted access to clinical services for children with lower NVIQ. Changes to DSM-5 criteria for language disorder removed this NVIQ requirement. This study sought to delineate the impact of varying…

Norbury, Courtenay Frazier; Gooch, Debbie; Baird, Gillian; Charman, Tony; Simonoff, Emily; Pickles, Andrew – Journal of Child Psychology and Psychiatry, 2016
Background: The youngest children in an academic year are reported to be educationally disadvantaged and overrepresented in referrals to clinical services. In this study we investigate for the first time whether these disadvantages are indicative of a mismatch between language competence at school entry and the academic demands of the classroom.…

Johnson, Mark H.; Gliga, Teodora; Jones, Emily; Charman, Tony – Journal of Child Psychology and Psychiatry, 2015
Background: Autism spectrum disorders (ASD) and attention deficit hyperactivity disorder (ADHD) are two of the most common neurodevelopmental disorders, with a high degree of co-occurrence. Methods: Prospective longitudinal studies of infants who later meet criteria for ASD or ADHD offer the opportunity to determine whether the two disorders share…

Wan, Ming Wai; Green, Jonathan; Elsabbagh, Mayada; Johnson, Mark; Charman, Tony; Plummer, Faye – Journal of Child Psychology and Psychiatry, 2013
Background: Recent models of the early emergence of autism spectrum disorder (ASD) propose that infant intrinsic risk susceptibilities in behaviour may be amplified by interaction within the early social environment into an increasingly atypical developmental trajectory. This study examines whether 6- and 12-month parent-infant interactions in…

Simonoff, Emily; Jones, Catherine R. G.; Baird, Gillian; Pickles, Andrew; Happe, Francesca; Charman, Tony – Journal of Child Psychology and Psychiatry, 2013
Background: Psychiatric problems are common in autism spectrum disorders (ASDs), but the reasons are poorly understood. We use a longitudinal population-representative cohort to examine for the first time the persistence of psychiatric problems and to identify risk factors for their occurrence and stability. Methods: Eighty-one 16-year olds (75…

Simonoff, Emily; Jones, Catherine R. G.; Pickles, Andrew; Happe, Francesca; Baird, Gillian; Charman, Tony – Journal of Child Psychology and Psychiatry, 2012
Introduction: Severe mood dysregulation and problems (SMP) in otherwise typically developing youth are recognized as an important mental health problem with a distinct set of clinical features, family history and neurocognitive characteristics. SMP in people with autism spectrum disorders (ASDs) have not previously been explored. Method: We…

Background: Autism spectrum disorders (ASD) are characterised by social and communication difficulties in day-to-day life, including problems in recognising emotions. However, experimental investigations of emotion recognition ability in ASD have been equivocal, hampered by small sample sizes, narrow IQ range and over-focus on the visual modality.…

Messinger, Daniel; Young, Gregory S.; Ozonoff, Sally; Dobkins, Karen; Carter, Alice; Zwaigenbaum, Lonnie; Landa, Rebecca J.; Charman, Tony; Stone, Wendy L.; Constantino, John N.; Hutman, Ted; Carver, Leslie J.; Bryson, Susan; Iverson, Jana M.; Strauss, Mark S.; Rogers, Sally J.; Sigman, Marian – Journal of the American Academy of Child & Adolescent Psychiatry, 2013
Objective: First-degree relatives of persons with an autism spectrum disorder (ASD) are at increased risk for ASD-related characteristics. As little is known about the early expression of these characteristics, this study characterizes the non-ASD outcomes of 3-year-old high-risk (HR) siblings of children with ASD. Method: Two groups of children…

Mandy, William P. L.; Charman, Tony; Skuse, David H. – Journal of the American Academy of Child & Adolescent Psychiatry, 2012
Objective: To use confirmatory factor analysis to test the construct validity of the proposed "DSM-5" symptom model of autism spectrum disorder (ASD), in comparison to alternative models, including that described in "DSM-IV-TR." Method: Participants were 708 verbal children and young persons (mean age, 9.5 years) with mild to severe autistic…

Pickles, Andrew; Simonoff, Emily; Conti-Ramsden, Gina; Falcaro, Milena; Simkin, Zoe; Charman, Tony; Chandler, Susie; Loucas, Tom; Baird, Gillian – Journal of Child Psychology and Psychiatry, 2009
Background: Several authors have highlighted areas of overlap in symptoms and impairment among children with autism spectrum disorder (ASD) and children with specific language impairment (SLI). By contrast, loss of language and broadly defined regression have been reported as relatively specific to autism. We compare the incidence of language loss…

Background: Recent studies of infant siblings of children diagnosed with autism have allowed for a prospective approach to examine the emergence of symptoms and revealed behavioral differences in the broader autism phenotype within the early years. In the current study we focused on a set of functions associated with visual attention, previously…

Loucas, Tom; Charman, Tony; Pickles, Andrew; Simonoff, Emily; Chandler, Susie; Meldrum, David; Baird, Gillian – Journal of Child Psychology and Psychiatry, 2008
Background: Autism spectrum disorders (ASD) and specific language impairment (SLI) are common developmental disorders characterised by deficits in language and communication. The nature of the relationship between them continues to be a matter of debate. This study investigates whether the co-occurrence of ASD and language impairment is associated…

Simonoff, Emily; Pickles, Andrew; Charman, Tony; Chandler, Susie; Loucas, Tom; Baird, Gillian – Journal of the American Academy of Child & Adolescent Psychiatry, 2008
A study on autism spectrum disorders is conducted because its early onset, lifelong persistence, and high levels of associated impairment is turning it into a major public health concern. Results show that psychiatric disorders are common in children with autism spectrum disorders but there were few associations between putative risk factors and…

Method: Design: Group randomised, controlled trial (3 groups: immediate treatment, delayed treatment, no treatment). Participants: 84 elementary school…
