Ability Profiles in Children with Autism: Influence of Age and IQ / Susan DICKERSON MAYES in Autism, 7-1 (March 2003)  

Public ISBD [article]  inAutism > 7-1 (March 2003) . - p.65-80 Titre : Ability Profiles in Children with Autism: Influence of Age and IQ Type de document : texte imprimé Auteurs : Susan DICKERSON MAYES, Auteur ; Susan L. CALHOUN, Auteur Article en page(s) : p.65-80 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : To understand the effect of IQ and age on ability in children with autism, psychological data were analyzed for 164 3- to 15-year-olds with autism (IQs 14-143). As age increased, so did IQ, which probably reflects both an actual increase in IQ over time and the likelihood that brighter children are diagnosed later. Early in life, 67 percent had normal motor and delayed speech milestones. Verbal IQ continued to lag behind non-verbal IQ during the preschool years. By school age, the gap between verbal and non-verbal IQs had closed. Visual reasoning exceeded graphomotor scores for all children, and surpassed IQ for most. Graphomotor scores were significantly below IQ for both high-IQ groups. For school-age children with low IQs, math, spelling, and writing scores were consistent with IQ and reading was above IQ. School-age children with high IQs had average reading, math, and spelling scores and a weakness in writing.

Anxiety, depression, and irritability in children with autism relative to other neuropsychiatric disorders and typical development / Susan DICKERSON MAYES in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 5-1 (January-March 2011) . - p.474-485 Titre : Anxiety, depression, and irritability in children with autism relative to other neuropsychiatric disorders and typical development Type de document : texte imprimé Auteurs : Susan DICKERSON MAYES, Auteur ; Susan L.

SMITH, Auteur Année de publication : 2011 Article en page(s) : p.474-485 Langues : Anglais (eng) Mots-clés : Anxiety Depression Irritability Autism ADHD Retardation Index. décimale : PER Périodiques Résumé : Maternal ratings of anxiety, depression, and irritability were analyzed in 1390 children (6–16 years of age), including 233 children with high functioning autism (HFA, IQ ≥ 80), 117 children with low functioning autism (LFA, IQ < 80), 187 typical children, and 853 children with other disorders. As a group, children with HFA were characterized as irritable and anxious, and children with LFA and ADHD-combined type were irritable only. Children with anxiety disorders were anxious only. Children with major depression or dysthymic disorder were depressed and irritable. Elevated levels of irritability, anxiety, or depression were not found in ADHD-inattentive type, mental retardation, brain injury, or typical development. The frequency of parent reported anxiety symptoms was similar for children with an anxiety disorder and HFA, though some symptoms were more severe in children with anxiety disorders. Children with depression had more frequent and more severe depressive symptoms than children with HFA. Mothers of 54% of children with HFA and 42% with LFA reported depressed mood in their children. Percentages were higher for anxiety (79% and 67%) and irritability (88% and 84%). These remarkably high percentages justify routinely assessing all children with autism for depression, anxiety, and irritability.

Assessing children with autism, mental retardation, and typical development using the Playground Observation Checklist / Daniel H. INGRAM in Autism, 11-4 (July 2007)

Ten behaviors were scored as present or absent using the Playground Observation Checklist. Children with autism were distinguished from children with mental retardation and typical development by their social problems, whereas children with typical development and mental retardation did not differ significantly in social competency. The four social behaviors on the checklist correctly identified 94 percent of the children as having or not having autism. All of the children with autism and all of the typical children were correctly classified. Our pilot findings suggest that the Playground Observation Checklist has potential as a simple and clinically useful component of a comprehensive evaluation for possible autism.

Autism and ADHD: Overlapping and discriminating symptoms / Susan DICKERSON MAYES in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)

The purpose of our study was to determine the degree to which core ADHD and autistic symptoms overlap in and discriminate between children 2–16 years of age with autism and ADHD. Our study demonstrated that 847 children with autism were easily distinguished from 158 children with ADHD. All children with autism had 15 or more of the 30 Checklist for Autism Spectrum Disorder symptoms (mean 22), and none of the children with ADHD did (mean 4). Three of the symptoms were present only in children with autism. Almost all 30 symptoms were found in over half of the children with autism, whereas none were present in the majority of children with ADHD-Inattentive type (ADHD-I) or in children with ADHD-Combined type (ADHD-C) without comorbid oppositional-defiant disorder. In contrast, ADHD symptoms were common in autism. Children with low and high functioning autism and ADHD-C did not differ on maternal ratings of attention deficit, impulsivity, and hyperactivity. For children with normal intelligence, nonsignificant differences were found between children with autism, ADHD-C, and ADHD-I on neuropsychological tests including measures of attention, working memory, processing speed, and graphomotor skills.

Autism Spectrum Disorder Phenotypes Based on Sleep Dimensions and Core Autism Symptoms / Kristina P. LENKER in Journal of Autism and Developmental Disorders, 55-12 (December 2025)

CALHOUN, Auteur Article en page(s) : p.4412-4424 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Previous studies have used cluster analysis to address the diagnostic heterogeneity of autism spectrum disorder, but have been limited by identifying subgroups solely on the basis of core autism symptoms. The present study aimed to identify sleep phenotypes and their clustering with core autism symptoms in youth diagnosed with autism. 1397 patients (1-17y, M = 6.1 ± 3.3y; M IQ = 88.5 ± 27.2; 81.2% male, 89.0% white) with autism. Principal component analysis (PCA) was performed on 10 sleep items from the Pediatric Behavior Scale. Latent class analyses (LCA) determined phenotypes characterized by core autism symptoms and sleep clusters, accounting for age, sex, Intelligence Quotient (IQ), and medication use.PCA identified three distinct sleep clusters (disturbed sleep, insufficient sleep and hypersomnolence) explaining 48.4% of the variance. LCA revealed four phenotypes based on core ASD symptoms and sleep clusters. Compared to Class 1 (54.8%) as the reference group, Class 2 (26.3%) had a similar degree of sleep problems, higher IQ and milder autism symptoms, less problems with selective attention/fearlessness; Class 3 (14.5%) was characterized by insufficient and disturbed sleep, perseveration and somatosensory disturbance, and higher medication use, while Class 4 (4.4%) was by hypersomnolence, problems with social interactions, and higher medication use.We found four distinct clustering of core autism symptoms and sleep problems differing in their sleep profiles as well as in relation to clinical characteristics, demographics, internalizing/externalizing symptoms, and functional outcomes. Our findings underscore the heterogeneity of autism based on sleep-wake problems, advocating for personalized therapeutic interventions targeting nighttime sleep and daytime alertness.
