Autism is diagnosed based on social and communication difficulties, restricted and repetitive behaviours and sensory anomalies. Existing evidence indicates that anxiety and atypical sensory features are associated with restricted and repetitive behaviours, but cannot clarify the order of emergence of these traits. This study uses data from a…

The current study explored the role of pre-existing and pandemic-time child, family or environmental factors in the presentation of mental health symptoms of autistic youth and their parents during the pandemic. Participants were parents/carers of autistic children (Autism Spectrum Treatment and Resilience Cohort, N = 67, M[subscript age] = 9…

Autism is frequently associated with difficulties with top-down attentional control, which impact on individuals' mental health and quality of life. The developmental processes involved in these attentional difficulties are not well understood. Using a data-driven approach, 2 samples (N = 294 and 412) of infants at elevated and typical likelihood…

We investigated the early sociocognitive battery (ESB), a novel measure of preverbal social communication skills, in children with autism participating in the Paediatric Autism Communication Trial-Generalised (PACT-G). The associations between ESB scores, language and autism symptoms were assessed in 249 children aged 2-11 years. The results show…

Previous studies have reported reduced quality of life in autism. Improving quality of life for autistic people is, therefore, a key priority for clinical research and practice. However, the relative impact of core autism traits (e.g. social-communication difficulties), as compared to associated mental health symptoms (e.g. anxiety, depression) on…

Stringer, Dominic; Kent, Rachel; Briskman, Jackie; Lukito, Steve; Charman, Tony; Baird, Gillian; Lord, Catherine; Pickles, Andrew; Simonoff, Emily – Autism: The International Journal of Research and Practice, 2020
Little is known about their stability and the factors that influence their persistence or change over the life-course. To address this, we use data from 158 participants from the Special Needs and Autism Project cohort studied at three time-points from 12 to 23 years. We used latent growth models to study the role of child, family, and contextual…

Palmer, Melanie; San José Cáceres, Antonia; Tarver, Joanne; Howlin, Patricia; Slonims, Vicky; Pellicano, Elizabeth; Charman, Tony – Autism: The International Journal of Research and Practice, 2020
The EarlyBird programme is a group-based psychoeducation intervention for parents of young children with autism. Although it is widely used in the United Kingdom, the evidence base for the programme is very limited. Using a mixed method, non-randomised research design, we aimed to test (1) the acceptability of the research procedures (recruitment,…

Milosavljevic, Bosiljka; Shephard, Elizabeth; Happé, Francesca G.; Johnson, Mark H.; Charman, Tony – Journal of Autism and Developmental Disorders, 2017
Anxiety and threat bias were examined in 6-8-year-old children at familial-risk for Autism Spectrum Disorder (ASD) and low-risk (LR, n = 37) controls. The high-risk (HR) group was divided into those who met diagnostic criteria for ASD (HR-ASD, n = 15) and those who did not (HR-non ASD, n = 24). The HR-ASD group had highest levels of…

Thomas, Michael S. C.; Davis, Rachael; Karmiloff-Smith, Annette; Knowland, Victoria C. P.; Charman, Tony – Developmental Science, 2016
This article outlines the "over-pruning hypothesis" of autism. The hypothesis originates in a neurocomputational model of the regressive sub-type (Thomas, Knowland & Karmiloff-Smith, 2011a, 2011b). Here we develop a more general version of the over-pruning hypothesis to address heterogeneity in the timing of manifestation of ASD,…

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…

The objective of this study is to investigate whether parentally-reported gastro-intestinal (GI) symptoms are increased in a population-derived sample of children with autism spectrum disorders (ASD) compared to controls. Participants included 132 children with ASD and 81 with special educational needs (SEN) but no ASD, aged 10-14 years plus 82…

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…

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…

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…

Yirmiya, Nurit; Charman, Tony – Journal of Child Psychology and Psychiatry, 2010
Autism is one of the most heritable neurodevelopmental conditions and has an early onset, with symptoms being required to be present in the first 3 years of life in order to meet criteria for the "core" disorder in the classification systems. As such, the focus on identifying a prodrome over the past 20 years has been on pre-clinical…
