Evaluation of the ADHD Rating Scale in Youth with Autism / Benjamin E. YERYS in Journal of Autism and Developmental Disorders, 47-1 (January 2017)
[article]
Titre : Evaluation of the ADHD Rating Scale in Youth with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Benjamin E. YERYS, Auteur ; Jenelle NISSLEY-TSIOPINIS, Auteur ; Ashley DE MARCHENA, Auteur ; Marley W. WATKINS, Auteur ; Ligia ANTEZANA, Auteur ; Thomas J. POWER, Auteur ; Robert T. SCHULTZ, Auteur Article en page(s) : p.90-100 Langues : Anglais (eng) Mots-clés : Autism Attention deficit/hyperactivity disorder Comorbidity Screening Factor analysis Index. décimale : PER Périodiques Résumé : Scientists and clinicians regularly use clinical screening tools for attention deficit/hyperactivity disorder (ADHD) to assess comorbidity without empirical evidence that these measures are valid in youth with autism spectrum disorder (ASD). We examined the prevalence of youth meeting ADHD criteria on the ADHD rating scale fourth edition (ADHD-RS-IV), the relationship of ADHD-RS-IV ratings with participant characteristics and behaviors, and its underlying factor structure in 386, 7–17 year olds with ASD without intellectual disability. Expected parent prevalence rates, relationships with age and externalizing behaviors were observed, but confirmatory factor analyses revealed unsatisfactory fits for one-, two-, three-factor models. Exploratory analyses revealed several items cross-loading on multiple factors. Implications of screening ADHD in youth with ASD using current diagnostic criteria are discussed.

[article]
Titre : “Frank” presentations as a novel research construct and element of diagnostic decision-making in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Ashley DE MARCHENA, Auteur ; Judith MILLER, Auteur Article en page(s) : p.653-662 Langues : Anglais (eng) Mots-clés : autism spectrum disorder diagnostic decision-making behavioral phenotype Index. décimale : PER Périodiques Résumé : Many individuals with ASD have a distinctive behavioral presentation that is recognizable within moments, a phenomenon we call “frank” ASD. This phenomenon has been discussed informally for decades, perhaps as “classic” ASD; however, there is no unitary “classic” presentation, and classic autism does not seem to correspond to level of functioning. Thus, neither “frank” nor “classic” autism has been delineated or studied as a research construct. To initiate the empirical study of frank ASD, we surveyed 151 clinicians, from a range of disciplines that diagnose ASD, about this phenomenon. Respondents completed a 13-item questionnaire about frank ASD, which was analyzed using a mixed-methods approach. Ninety-seven percentage of respondents were familiar with the phenomenon. Respondents estimated that 40% of the ASD population has a frank presentation. Respondents reported the most highly specific behaviors associated with frank presentations were a general sense of impaired reciprocity, quality of eye contact, atypical vocal prosody, presence of motor mannerisms, and atypical gait or posture. In general, respondents reported detecting frank features rapidly, with the majority forming their impressions within the first ten minutes of interaction or observation. Although unstudied empirically, “frank” presentations of ASD are familiar to diagnosing clinicians, and appear to be based on behaviors both central to ASD diagnostic criteria (e.g., impaired reciprocity), and absent from diagnostic criteria (e.g., atypical gait or posture). We discuss these findings within the context of diagnostic decision-making and behavioral phenotyping of ASD.

Williams, Auteur ; Sherira Fernandes, Auteur ; Rebecca P. THOMAS, Auteur ; Leslie A. McClure, Auteur ; Sarah DUFEK, Auteur ; Deborah FEIN, Auteur ; Aubyn C. STAHMER, Auteur ; Diana L. ROBINS, Auteur Article en page(s) : p.1138-1144 Langues : Anglais (eng) Mots-clés : autism diagnosis diagnostic confidence early detection initial impression toddlers Index. décimale : PER Périodiques Résumé : Abstract Reducing the age of first autism diagnosis facilitates access to critical early intervention services. A current ?waitlist crisis? for autism diagnostic evaluation thus demands that we consider novel use of available clinical resources. Previous work has found that expert autism clinicians can identify autism in young children with high specificity after only a brief observation; rapid identification by non-experts remains untested. In the current study, 252 children ages 12?53?months presented for a comprehensive autism diagnostic evaluation. We found that junior clinicians in training to become autism specialists (n?=?29) accurately determined whether or not a young child would be diagnosed with autism in the first five minutes of the clinic visit in 75% of cases. Specificity of brief observations was high (0.92), suggesting that brief observations may be an effective tool for triaging young children toward autism-specific interventions. In contrast, the lower negative predictive value (0.71) of brief observations, suggest that they should not be used to rule out autism. When trainees expressed more confidence in their initial impression, their impression was more likely to match the final diagnosis. These findings add to a body of literature showing that clinical observations of suspected autism should be taken seriously, but lack of clinician concern should not be used to rule out autism or overrule other indicators of likely autism, such as parent concern or a positive screening result.

Titre : Measuring dyspraxia in autism using a five-minute praxis exam Type de document : Texte imprimé et/ou numérique Auteurs : Ashley DE MARCHENA, Auteur ; Casey J. ZAMPELLA, Auteur ; Zachary DRAVIS, Auteur ; Juhi PANDEY, Auteur ; Stewart MOSTOFSKY, Auteur ; Robert T. SCHULTZ, Auteur Année de publication : 2023 Article en page(s) : 102200 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Praxis Motor skills Nonverbal communication Imitation Adaptive behavior skills Index. décimale : PER Périodiques Résumé : Background Difficulties with praxis, the ability to perform learned skilled movements, have been robustly demonstrated in autism spectrum disorder (autism). However, praxis assessment is not routinely included in autism characterization batteries, in part because it is traditionally time consuming to administer and score. We test whether dyspraxia in autism can be captured with a brief measure. Method Youth with autism (n = 41) and matched typically developing controls (n = 32), aged 8-16 years, completed a 5-min praxis battery. The 19-item battery included four subtests: gesture to command, tool use, familiar imitation, and meaningless imitation. Video recordings were coded for error types and compared to participant characterization variables. Results Consistent with research using a lengthy battery, autistic youth made more errors overall, with a large effect size. Groups demonstrated similar distributions of error types, suggesting that dyspraxia in autism is not limited to a particular error form. In the autism group, praxis was associated with adaptive functioning, but not autism traits. Conclusions A shortened battery is sufficiently sensitive to praxis differences between autistic and typically developing youth, increasing the feasibility of including praxis within clinical assessments or larger research batteries aimed at testing relationships with downstream skills.

Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Camouflage First impressions Sex differences Index. décimale : PER Périodiques Résumé : BACKGROUND: Individuals with autism spectrum disorder (ASD) are characterized by social communication challenges and repetitive behaviors that may be quickly detected by experts (Autism Res 10:653-62, 2017; American Psychiatric Association, Diagnostic and statistical manual of mental disorders, 2013). Recent research suggests that even naïve non-experts judge a variety of human dimensions using narrow windows of experience called "first impressions." Growing recognition of sex differences in a variety of observable behaviors in ASD, combined with research showing that some autistic girls and women may "camouflage" outward symptoms, suggests it may be more difficult for naïve conversation partners to detect ASD symptoms in girls. Here, we explore the first impressions made by boys and girls with ASD and typically developing (TD) peers. METHODS: Ninety-three school-aged children with ASD or TD were matched on IQ; autistic girls and boys were additionally matched on autism symptom severity using the ADOS-2. Participants completed a 5-minute "get-to-know-you" conversation with a new young adult acquaintance. Immediately after the conversation, confederates rated participants on a variety of dimensions. Our primary analysis compared conversation ratings between groups (ASD boys, ASD girls, TD boys, TD girls). RESULTS: Autistic girls were rated more positively than autistic boys by novel conversation partners (better perceived social communication ability), despite comparable autism symptom severity as rated by expert clinicians (equivalent true social communication ability). Boys with ASD were rated more negatively than typical boys and typical girls by novel conversation partners as well as expert clinicians. There was no significant difference in the first impressions made by autistic girls compared to typical girls during conversations with a novel conversation partner, but autistic girls were rated lower than typical girls by expert clinicians. LIMITATIONS: This study cannot speak to the ways in which first impressions may differ for younger children, adults, or individuals who are not verbally fluent; in addition, there were more autistic boys than girls in our sample, making it difficult to detect small effects. CONCLUSIONS: First impressions made during naturalistic conversations with non-expert conversation partners could-in combination with clinical ratings and parent report-shed light on the nature and effects of behavioral differences between girls and boys on the autism spectrum.
