First developed for preschoolers with ASD, this study tests an expanded age range (2-to-18 years). The ACFS rates the child's typical and best (i.e., capacity) performance. Qualitative methods tested parent and clinician perspectives of the ACSF age expansion using content analysis. The ACSF was used twice by parents and professionals for the same child/youth. Reliabilities were assessed using weighted kappa. Content validity supported the ACSF's applicability, clarity, and usability. The ACSF adaptations did not change its original construct. Reliability were calculated from 90 parent and professional Time-1 and Time-2 ratings for children/youth (2.1-15.6 years). Results showed good-to-very good intra-rater agreement (typical) and good inter-rater agreement (capacity).

Alexithymia in Parents of Children with Autism Spectrum Disorder / Peter SZATMARI in Journal of Autism and Developmental Disorders, 38-10 (November 2008)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 38-10 (November 2008) . - p.1859-1865 Titre : Alexithymia in Parents of Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Peter SZATMARI, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Stelios GEORGIADES, Auteur ; Jeremy GOLDBERG, Auteur ; Terry BENNETT, Auteur ; Eric DUKU, Auteur Année de publication : 2008 Article en page(s) : p.1859-1865 Langues : Anglais (eng) Mots-clés : Autism Broader-autism-phenotype Emotion-processing Alexithymia Intermediate-phenotype Index. décimale : PER Périodiques Résumé : Given the recent findings regarding the association between alexithymia and Autism Spectrum Disorder (ASD) and the accumulating evidence for the presence of the Broader Autism Phenotype (BAP) in relatives of individuals with ASD, we further explored the construct of alexithymia in parents of children with ASD as a potential part of the BAP. We hypothesized that (a) parents of children with ASD will demonstrate higher impairment in their emotion processing when compared to controls, and (b) high impairment in emotion processing in parents will be associated with severity of symptoms in children with ASD. Psychometric and diagnostic data were collected on 188 children with a diagnosis of ASD. The Toronto Alexithymia Scale (TAS-20) was completed by 439 parents of children with ASD and a control group of 45 parents of children with Prader Willi syndrome (PW). Results show that ASD parents score higher than controls on the TAS-20 total score. Within the ASD group, children of fathers with high alexithymia score higher on repetitive behaviour symptoms compared to children of fathers with low alexithymia. The alexithymia trait appears to be one of the many building blocks that make up the BAP.

Characterizing the ASD-ADHD phenotype: measurement structure and invariance in a clinical sample / Aneta D. KRAKOWSKI in Journal of Child Psychology and Psychiatry, 63-12 (December 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-12 (December 2022) . - p.1534-1543 Titre : Characterizing the ASD-ADHD phenotype: measurement structure and invariance in a clinical sample Type de document : Texte imprimé et/ou numérique Auteurs : Aneta D. KRAKOWSKI, Auteur ; Katherine Tombeau COST, Auteur ; Peter SZATMARI, Auteur ; Evdokia ANAGNOSTOU, Auteur ; Jennifer CROSBIE, Auteur ; Russell SCHACHAR, Auteur ; Eric DUKU, Auteur ; Stelios GEORGIADES, Auteur ; Muhammad AYUB, Auteur ; Elizabeth KELLEY, Auteur ; Rob NICOLSON, Auteur ; Eleanor PULLENAYEGUM, Auteur ; Carolina BARNETT-TAPIA, Auteur Article en page(s) : p.1534-1543 Langues : Anglais (eng) Mots-clés : Humans  Attention Deficit Disorder with Hyperactivity/diagnosis/genetics  Autism Spectrum Disorder/diagnosis  Parents  Phenotype  Surveys and Questionnaires  Adhd  Asd  factor analysis  measurement invariance  measurement structure Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) have considerable overlap, supporting the need for a dimensional framework that examines neurodevelopmental domains which cross traditional diagnostic boundaries. In the following study, we use factor analysis to deconstruct the ASD-ADHD phenotype into its underlying phenotypic domains and test for measurement invariance across adaptive functioning, age, gender and ASD/ADHD clinical diagnoses. METHODS: Participants included children and youth (aged 3-20 years) with a clinical diagnosis of ASD (n=727) or ADHD (n=770) for a total of 1,497 participants. Parents of these children completed the Social Communication Questionnaire (SCQ), a measure of autism symptoms, and the Strengths and Weaknesses of ADHD and Normal Behaviour (SWAN) questionnaire, a measure of ADHD symptoms. An exploratory factor analysis (EFA) was performed on combined SCQ and SWAN items. This was followed by a confirmatory factor analysis (CFA) and tests of measurement invariance. RESULTS: EFA revealed a four-factor solution (inattention, hyperactivity/impulsivity, social-communication, and restricted, repetitive, behaviours and interests (RRBI)) and a CFA confirmed good model fit. This solution also showed good model fit across subgroups of interest. CONCLUSIONS: Our study shows that a combined ASD-ADHD phenotype is characterized by two latent ASD domains (social communication and RRBIs) and two latent ADHD domains (inattention and hyperactivity/impulsivity). We established measurement invariance of the derived measurement model across adaptive functioning, age, gender and ASD/ADHD diagnoses.

Comparing early language development in monolingual- and bilingual- exposed young children with autism spectrum disorders / Kaori OHASHI J. in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)

The groups were matched with regard to chronological age at the time of language assessment and nonverbal IQ score, then compared with regard to the severity of children's autism-related communication impairment, age of first words, age of first phrases, receptive language scores, expressive language scores, and functional communication scores. Univariate ANOVAs were performed for autism-related communication impairment, age of first words, and age of first phrases. A MANCOVA, with the total number of speech-language and applied behavior analysis intervention hours entered as a covariate, was performed on the remaining dependent variables. No statistically significant differences between the two groups on any of the language measures were observed. The results suggest that a bilingual language environment does not disadvantage young children with autism in the early stages of language development. Study limitations and research and clinical implications are discussed.

Construct Validity of the Autism Classification System of Functioning: Social Communication (ACSF:SC) Across Childhood and Adolescence / Diana TAJIK-PARVINCHI in Journal of Autism and Developmental Disorders, 53-8 (August 2023)

Participants included 145 parents of children with autism (2-19 years). The degree of convergent and discriminant validity between parent reported ACSF and subscales from Social Responsiveness Scale 2nd edition and Behavior Assessment System for Children, 3rd Edition were examined against a priori hypotheses. We examined construct validity in the entire sample as well as in specific age cohorts. Our findings suggest that ACSF can provide a valid classification system of social communication ability in children with autism 2-19 years of age, and its two subscales may be used to examine different aspects of social communication ability.
