The Construct Validity of the Childhood Joint Attention Rating Scale (C-JARS) in School-Aged Autistic Children.

Preliminary evidence from the Childhood Joint Attention Rating Scale (C-JARS; Mundy et al., 2017) suggests symptoms related to diminished joint attention and the spontaneous sharing of experience with others can be assessed with a parent-report measure in children and adolescents with autism. This study was designed to expand on the previous study by examining the validity of both a Social Symptom (SS) and a Prosocial (PS) scale of the C-JARS in a study of school-aged autistic children (n  = 89) with and without co-occurring intellectual disability (ID), as well as an age matched neurotypical sample (n  = 62). Results indicated that both C-JARS scales were sensitive and specific with respect to identifying the diagnostic status of the children. In addition, the PS scale was sensitive to differences in cognitive abilities (IQ) and sex differences in the autism group. These results are consistent with the hypothesis that joint attention and spontaneous sharing of experience symptoms are not only characteristic of preschool children with autism but may also constitute a developmentally continuous dimension of the social phenotype of autism that can be measured in school-aged children.

Observing Visual Attention and Writing Behaviors During a Writing Assessment: Comparing Children with Autism Spectrum Disorder to Peers with Attention-Deficit/Hyperactivity Disorder and Typically Developing Peers.

Children with autism spectrum disorder (ASD) demonstrate heterogeneous writing skills that are generally lower than their typically developing (TD) peers and similar to peers with attention difficulties like attention-deficit/hyperactivity disorder (ADHD). Recent evidence suggests children with ASD spend less time engaging in writing tasks compared to their peers, but previous studies have not examined engagement specifically within the writing task environment. This study used video observation data collected from 121 school-age children (60 children with ASD, 32 children with ADHD, and 29 TD children) to compare differences in visual attention and writing task behaviors and relationships between task behaviors and age, cognitive skills, and ASD and ADHD symptom severity. Findings indicated that groups mostly spent time looking at and writing on the draft, though this was lowest in the ASD group. No differences were found between the ASD and ADHD groups after accounting for task behavior durations as percentages of total used task time. Groups spent little time looking at their outlines and looking away from the task, with all groups spending relatively more time looking at the task picture. Time spent engaged with the draft showed a positive relationship with writing performance across groups, but a negative relationship between time spent looking at the task picture and writing performance only appeared for the ADHD group. The ASD and ADHD groups showed negative associations between draft engagement and ASD symptom severity but not ADHD symptom severity. Implications are discussed for understanding writing task engagement in research and instructional contexts. LAY SUMMARY: Children with autism spectrum disorder (ASD) demonstrate variable writing skills. Here, we examine how children with ASD engage during a writing task by using video observation data to compare their engagement to peers with and without attention difficulties. Findings indicate (a) lower draft engagement and similar task disengagement in children with ASD compared to their peers and (b) moderate-to-strong relationships between writing scores and ASD symptom severity with within-task engagement in children with ASD and their peers with attention difficulties.

A Developmental Study of Mathematics in Children with Autism Spectrum Disorder, Symptoms of Attention Deficit Hyperactivity Disorder, or Typical Development.

This study examined mathematics achievement in school-aged children with autism spectrum disorder (ASD), symptoms of attention-deficit/hyperactivity disorder (ADHD), or typical development (TD) over a 30-month period and the associations between cognitive and reading abilities with mathematics achievement in children with ASD. Seventy-seven children with ASD without intellectual disability (ASD-WoID), 39 children with ADHD, and 43 children with TD participated in this study. The results revealed that the ASD-WoID and ADHD samples displayed significant and comparable delays in problem solving and calculation abilities. Lower VIQ was related to lower math achievement across all subgroups. The ASD-WoID sample differed from comparison samples in terms of their pattern of mathematical achievement and the role of cognitive abilities in the development of mathematics competence.

Overt planning behaviors during writing in school-age children with autism spectrum disorder and attention-deficit/hyperactivity disorder.

BACKGROUND: The planning behaviors of children with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) during writing remain overlooked. Targeted examination of planning behaviors may help to better understand their heterogeneous writing skills. AIMS: This study examined overt planning behaviors of three groups of school-age children (ASD, ADHD, and typically developing [TD]) during the planning stage of a standardized narrative writing assessment. Aims explored group differences in time spent planning, between- and within-group differences in overt planning behaviors, and relationships between planning behaviors and writing performance as well as age, cognitive skills, and diagnostic symptom severity. METHODS AND PROCEDURES: This study included 121 9-17-year-old children (60 ASD, 32 ADHD, and 29 TD). Video recordings captured overt planning behaviors during a two-minute prewriting planning stage. OUTCOMES AND RESULTS: Not all participants planned, but group membership overwhelmingly did not influence planning likelihood. Groups differed in time spent engaging with the outline (29 %-70 %), with the TD group spending the most time. Groups spent similar amounts of time looking away from the task (< 10 %) and looking at the task picture (20 %-33 %). The TD and ASD groups demonstrated more similar within-group-level differences in planning behavior s, while the ADHD group appeared more variable. The ADHD and TD groups but not the ASD group showed stronger associations between planning behaviors and writing performance. CONCLUSIONS AND IMPLICATIONS: Children with ASD and ADHD differed relative to each other and to TD peers in specific planning behaviors. Implications are discussed regarding instructional practices and needed future research to examine planning during writing in children with developmental disabilities.

Self-Esteem, Internalizing Symptoms, and Theory of Mind in Youth With Autism Spectrum Disorder.

Self-esteem is a potent indicator of mental health in typically developing (TYP) individuals. It is surprising that there have been few comprehensive investigations of self-esteem in children and adolescents with autism spectrum disorder (ASD), given that they are at high risk for comorbid mental health problems, such as depression and anxiety. The objectives of the current study were to assess how youth with ASD rate their self-esteem compared to age-matched TYP youth and to examine how self-esteem relates to internalizing psychopathology and theory of mind in the two groups. Seventy-three children and adolescents, ages 9 to 17, were administered a battery of questionnaires assessing self-esteem and internalizing symptoms, as well as tasks designed to measure theory of mind. Results indicated that youth with ASD rated their self-esteem significantly lower than did TYP youth. Self-esteem was strongly related to depression in both groups but was negatively related to theory of mind only for youth with ASD. These results may provide important insights into how individuals with ASD form evaluations of their own self-worth and illustrate how increasing self-awareness in individuals with ASD is not without risks.

Attention and written expression in school-age, high-functioning children with autism spectrum disorders.

High-functioning children with autism spectrum disorders often find writing challenging. These writing difficulties may be specific to autism spectrum disorder or to a more general clinical effect of attention disturbance, as these children are often comorbid for attention-deficit/hyperactivity disorder (ADHD) symptomatology (and children with attention-deficit/hyperactivity disorder often also find writing challenging). To examine this issue, this study investigated the role of attention disturbance on writing in 155 school-age children across four diagnostic groups: high-functioning autism spectrum disorder (HFASD) with lower ADHD symptoms (HFASD-L), HFASD with higher ADHD symptoms (HFASD-H), ADHD symptoms but no autism spectrum disorder symptoms, and typical development. Both HFASD subgroups and the ADHD group displayed lower word production writing scores than the typical development group, but the clinical groups did not differ. The HFASD-H and ADHD groups had significantly lower theme development and text organization writing scores than the typical development group, but the HFASD-L and typical development groups were not significantly different. The findings support prior research reporting writing problems in children with autism spectrum disorder but also suggest that children with HFASD-H may be at greater risk for writing difficulties than children with HFASD-L. Better understanding the role of attention in writing development could advance methods for assessment and intervention for children with high-functioning autism spectrum disorder at risk for writing difficulties.

The Scope and Nature of Reading Comprehension Impairments in School-Aged Children with Higher-Functioning Autism Spectrum Disorder.

This study of 8-16-year-olds was designed to test the hypothesis that reading comprehension impairments are part of the social communication phenotype for many higher-functioning students with autism spectrum disorder (HFASD). Students with HFASD (n = 81) were compared to those with high attention-deficit/hyperactivity disorder symptomatology (ADHD; n = 39), or typical development (TD; n = 44), on a comprehensive battery of oral language, word recognition, and reading comprehension measures. Results indicated that students with HFASD performed significantly lower on the majority of the reading and language tasks as compared to TD and ADHD groups. Structural equation models suggested that greater ASD symptomatology was related to poorer reading comprehension outcomes; further analyses suggested that this relation was mediated by oral language skills.

The Stability of Self-Reported Anxiety in Youth with Autism Versus ADHD or Typical Development.

Children with autism spectrum disorder (ASD) are at risk for anxiety symptoms. Few anxiety measures are validated for individuals with ASD, and the nature of ASD raises questions about reliability of self-reported anxiety. This study examined longitudinal stability and change of self-reported anxiety in higher functioning youth with ASD (HFASD) compared to youth with symptoms of attention deficit hyperactivity disorder and typical development (TD) using the Multidimensional Anxiety Scale for Children (March, 2012; March et al. J Am Acad Child Adolesc Psychiatry 36(4):554-565, 1997). Diagnostic groups demonstrated comparable evidence of stability for most dimensions of anxiety. The HFASD group displayed higher anxiety than both comparison groups, especially physical symptoms. These findings have implications for identification and measurement of anxiety in ASD.

A Comprehensive Examination of Reading Heterogeneity in Students with High Functioning Autism: Distinct Reading Profiles and Their Relation to Autism Symptom Severity.

The goal of this study was to identify unique profiles of readers in a sample of 8-16 year olds with higher functioning autism spectrum disorders (HFASD) and examine the profiles in relation to ASD symptom severity. Eighty-one students were assessed utilizing a comprehensive reading battery that included basic word reading, language, and comprehension. Using Latent Profile Analysis, four empirically distinct profiles of readers emerged. Next, using the Autism Diagnostic Observation Schedule, Second Edition (Lord et al., Autism diagnostic observation schedule, 2nd edn, Western Psychological Services, Torrance, CA, 2012), analyses were conducted to determine if significant differences existed between profiles as a result of ASD symptomatology. Findings demonstrate the heterogeneous nature of reading profiles in students with HFASD and significant differences between the reading profiles and ASD symptom severity.

Brief Report: Joint Attention and Information Processing in Children with Higher Functioning Autism Spectrum Disorders.

Theory suggests that information processing during joint attention may be atypical in children with Autism Spectrum Disorder (ASD). This hypothesis was tested in a study of school-aged children with higher functioning ASD and groups of children with symptoms of ADHD or typical development. The results indicated that the control groups displayed significantly better recognition memory for pictures studied in an initiating joint attention (IJA) rather than responding to joint attention (RJA) condition. This effect was not evident in the ASD group. The ASD group also recognized fewer pictures from the IJA condition than controls, but not the RJA condition. Atypical information processing may be a marker of the continued effects of joint attention disturbance in school aged children with ASD.
