Associations between theory of mind and conduct problems in autistic and nonautistic youth / Virginia CARTER LENO in Autism Research, 14-2 (February 2021)  

Public ISBD [article]  inAutism Research > 14-2 (February 2021) . - p.276-288 Titre : Associations between theory of mind and conduct problems in autistic and nonautistic youth Type de document : Texte imprimé et/ou numérique Auteurs : Virginia CARTER LENO, Auteur ; Susie CHANDLER, Auteur ; Phillipa WHITE, Auteur ; Isabel YORKE, Auteur ; Tony CHARMAN, Auteur ; Catherine R. G. JONES, Auteur ; Francesca HAPPE, Auteur ; Gillian BAIRD, Auteur ; Andrew PICKLES, Auteur ; Emily SIMONOFF, Auteur Article en page(s) : p.276-288 Langues : Anglais (eng) Mots-clés : Adhd  Quest  Snap  autism  cognition  conduct problems  theory of mind Index. décimale : PER Périodiques Résumé : Many autistic young people exhibit co-occurring behavior difficulties, characterized by conduct problems and oppositional behavior. However, the causes of these co-occurring difficulties are not well understood. Impairments in theory of mind (ToM) are often reported in autistic individuals and have been linked to conduct problems in nonautistic individuals. Whether an association between ToM ability and conduct problems exists in autistic populations, whether this association is similar between individuals who are autistic versus nonautistic, and whether these associations are specific to conduct problems (as opposed to other domains of psychopathology) remains unclear. ToM ability was assessed using the Frith-Happé Triangles task in a pooled sample of autistic (N = 128; mean age 14.78?years) and nonautistic youth (N = 50; mean age 15.48?years), along with parent-rated psychiatric symptoms of conduct problems, hyperactivity/inattention and emotional problems. Analyses tested ToM ability between autistic versus nonautistic participants, and compared associations between ToM performance and conduct problems between the two groups. Where no significant group differences in associations were found, the pooled association between ToM and conduct problems was estimated in the combined sample. Results showed no evidence of moderation in associations by diagnostic status, and an association between poorer ToM ability and higher levels of conduct problems, hyperactivity/inattention and emotional problems across the total sample. However, these associations became nonsignificant when adjusting for verbal IQ. Results provide support for theoretical models of co-occurring psychopathology in autistic populations, and suggest targets for intervention for conduct problems in autistic youth. LAY SUMMARY: Many young people with autism spectrum disorder show co-occurring behavior problems, but the causes of these are not well understood. This paper found an association between difficulties recognizing what others think and intend (so-called "theory of mind") in a simple animated task, and emotional and behavioral problems in autistic and nonautistic young people. However, a substantial part of this association was explained by individual differences in verbal ability. These findings may have implications for intervention efforts to improve young people's mental health.

Callous-unemotional traits in youth with autism spectrum disorder (ASD): replication of prevalence estimates and associations with gaze patterns when viewing fearful faces / Virginia CARTER LENO in Development and Psychopathology, 33-4 (October 2021)

However, past work has used measures not specifically designed to measure CU traits and has not examined whether decreased attention to the eyes reported in non-ASD populations is also present in individuals with ASD. The current paper uses a measure specifically designed to measure CU traits to estimate prevalence in a large community-based ASD sample. Parents of 189 adolescents with ASD completed questionnaires assessing CU traits, and emotional and behavioral problems. A subset of participants completed a novel emotion recognition task (n = 46). Accuracy, reaction time, total looking time, and number of fixations to the eyes and mouth were measured. Twenty-two percent of youth with ASD scored above a cut-off expected to identify the top 6% of CU scores. CU traits were associated with longer reaction times to identify fear and fewer fixations to the eyes relative to the mouth during the viewing of fearful faces. No associations were found with accuracy or total looking time. Results suggest the mechanisms that underpin CU traits may be similar between ASD and non-ASD populations.

There is evidence based on parental report that parenting interventions reduce child EBPs. More objective measures of child EBPs should supplement parent reported outcomes in trials. We describe the development of a new measure of child and parenting behavior, the Observation Schedule for Children with Autism-Anxiety, Behaviour and Parenting (OSCA-ABP). Participants were 83 parents/carers and their 4-8-year-old autistic children. The measure demonstrated good variance and potential sensitivity to change. Child and parenting behavior were reliably coded among verbal and minimally verbal children. Associations between reports from other informants and observed behavior showed the measure had sufficient convergent validity. The measure has promise to contribute to research and clinical practice in autism mental health beyond objective measurement in trials.

Factors associated with mental health symptoms among UK autistic children and young people and their parents during the COVID-19 pandemic / Melanie PALMER in Autism, 27-7 (October 2023)  

Public ISBD [article]  inAutism > 27-7 (October 2023) . - p.2098-2111 Titre : Factors associated with mental health symptoms among UK autistic children and young people and their parents during the COVID-19 pandemic Type de document : Texte imprimé et/ou numérique Auteurs : Melanie PALMER, Auteur ; Susie CHANDLER, Auteur ; Virginia CARTER LENO, Auteur ; Farah MGAIETH, Auteur ; Isabel YORKE, Auteur ; Matthew HOLLOCKS, Auteur ; Andrew PICKLES, Auteur ; Vicky SLONIMS, Auteur ; Stephen SCOTT, Auteur ; Tony CHARMAN, Auteur ; Emily SIMONOFF, Auteur Article en page(s) : p.2098-2111 Langues : Anglais (eng) Mots-clés : autism  children and young people  COVID-19 pandemic  mental health  parents Index. décimale : PER Périodiques Résumé : 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, Mage = 9?years) and adolescents (QUEST cohort, N=112, Mage = 17?years). Parents completed an online survey that asked about child and parental mental health, infection experience, and changes to education arrangements, family life, housing and finances during the pandemic. Pre-existing measures of mental health, autism and adaptive functioning were also utilised. More engagement and enjoyment in education provision and going outside was associated with better child and parental mental health. In multivariate multiple linear regression models, more pre-existing attention deficit hyperactivity disorder symptoms were associated with more behavioural/attention deficit hyperactivity disorder symptoms during the pandemic in the pre-adolescent cohort, and with greater emotional symptoms in the adolescent cohort. More pre-existing parental mental health problems were associated with more parental mental health symptoms during the pandemic in both cohorts. Knowledge of pre-existing mental health and pandemic-related stressors may help care planning. Encouraging engagement and enjoyment in education and promoting physical exercise are key intervention targets. Ensuring access to attention deficit hyperactivity disorder medication and support is important, especially if this is managed jointly across school and home.Lay abstractWhat is already known about the topic: The COVID-19 pandemic and the associated restrictions impacted all of society. There is emerging evidence showing a range of impacts on autistic children and young people and their families. Further research that looks at how individuals coped during the pandemic while considering how they were doing before the pandemic is needed.What this paper adds: This article explores whether how well autistic youth were doing before the pandemic influenced how they coped during the pandemic. It also looked at how well their parents were doing during the pandemic and whether any pre-pandemic factors influenced how they coped. Samples of both primary-school-aged autistic children and autistic teenagers and their parents were surveyed to answer these questions. More engagement and enjoyment in education provision during the pandemic and getting outside more were linked with better child and parental mental health during the pandemic. More attention deficit hyperactivity disorder before the pandemic was linked with more attention deficit hyperactivity disorder and behavioural problems during the pandemic in primary-school-aged autistic children, and more emotional problems during the pandemic in autistic teenagers. Parents with more mental health problems during the pandemic had more mental health problems before the pandemic.Implications for practice, research or policy: Encouraging engagement and enjoyment in education and promoting physical exercise are key intervention targets.

Pathways to adaptive functioning in autism from early childhood to adolescence / Susie CHANDLER in Autism Research, 15-10 (October 2022)

However, the clinical features associated with these difficulties are less well understood. This study examines longitudinal and contemporaneous associations of adaptive functioning in autistic youth across a wide ability range. Parent-reported autism symptoms, co-occurring emotional, behavioral and attention deficit hyperactivity disorder (ADHD) symptoms, and IQ were assessed in early childhood (M age 7 years; T1) and 6 years later in adolescence (M age 13 years; T2) in 179 autistic youth. Adaptive functioning was assessed at T2. Structural equation modeling estimated pathways to adaptive functioning from autism, and psychiatric symptoms at T1 and T2, testing whether associations were driven by continuity of behaviors from T1 to T2 or their contemporaneous effect at T2, or both, controlling for T1 IQ. Lower adaptive functioning at T2 was associated with higher T1 and T2 ADHD symptoms (Î2 = -0.14, andÎ2 = -0.21) but not behavioral nor emotional symptoms at either timepoint. Lower adaptive functioning at T2 was also associated with lower T1 IQ (Î2 = 0.43) and higher social communication symptoms (Î2 = -0.37) at T2 but not T1, but the relationship with ADHD symptoms remained. Paths were not moderated by sex or IQ. Increased symptoms of ADHD, both in early childhood and contemporaneously, were associated with reduced adaptive functioning in adolescence. Co-occurring ADHD may be a modifiable risk factor for adaptive function impairments and should be routinely assessed and when present evidence-based treatments initiated which may benefit adaptive functioning outcomes. LAY SUMMARY: Adaptive functioning is lower in many autistic individuals to a greater extent than would be expected based on IQ.
