Development and Psychometric Evaluation of the Hansen Research Services Matrix Adaptive Test: A Measure of Nonverbal IQ / J. A. HANSEN in Journal of Autism and Developmental Disorders, 49-7 (July 2019)
[article]
Titre : Development and Psychometric Evaluation of the Hansen Research Services Matrix Adaptive Test: A Measure of Nonverbal IQ Type de document : Texte imprimé et/ou numérique Auteurs : J. A. HANSEN, Auteur Article en page(s) : p.2721-2732 Langues : Anglais (eng) Mots-clés : Computer adaptive test Fluid intelligence Iq Instrument development Item response theory Nonverbal IQ Online phenotyping Psychometrics Raven's Standard Progressive Matrices Index. décimale : PER Périodiques Résumé : Assessment of individuals on the autism spectrum often includes a measure of nonverbal IQ. One such measure is the Raven's Standard Progressive Matrices (RSPM). For large research studies with participants distributed nationally it is desirable for assessments to be available online. Because time is a premium, it is ideal that the measure produces accurate scores quickly. The Hansen Research Services Matrix Adaptive Test (HRS-MAT) addresses these needs and with similar psychometric properties of the RSPM. Scores based on the HRS-MAT correlated at r = .81 with those of the RSPM. In adult-child pairs, HRS-MAT scores correlated at approximately r = .50. Details from respondents in a national sample and psychometric properties including reliability and validity are discussed.

Titre : Testing nonverbal IQ in children with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Nicole BARDIKOFF, Auteur ; Margaret MCGONIGLE-CHALMERS, Auteur Article en page(s) : p.1200-1207 Langues : Anglais (eng) Mots-clés : WISC-III WISC-IV KABC-II Nonverbal IQ Children with Autism Spectrum Disorders Index. décimale : PER Périodiques Résumé : Abstract 15 high-functioning school aged children with ASD and 15 neurotypically developing age matched controls were assessed using the WISC-IV and the KABC-II in order to assess whether the WISC-IV has rectified problems associated with the WISC-III's undue emphasis on timing measures. No significant group differences were found for the PRI sub-scale of the WISC-IV nor for the nonverbal scale of the KABC-II, but the ASD group scored significantly lower than controls on the Processing Speed Index of the WISC-IV. This supports the need to isolate of timing criteria when IQ testing in populations with ASD, as is now the case with the WISC-IV. However significantly higher scores were obtained for the KABC-II versus the PRI for children with ASD only. The reasons for this are discussed with regard to a possible cultural bias in the Picture Concepts subtest of the WISC-IV.

Titre : Executive functioning in children with specific language impairment Type de document : Texte imprimé et/ou numérique Auteurs : Lucy A. HENRY, Auteur ; David J. MESSER, Auteur ; Gilly NASH, Auteur Année de publication : 2012 Article en page(s) : p.37-45 Langues : Anglais (eng) Mots-clés : Specific language impairment executive functioning children verbal IQ nonverbal IQ Index. décimale : PER Périodiques Résumé : Background: A limited range of evidence suggests that children with specific language impairment (SLI) have difficulties with higher order thinking and reasoning skills (executive functioning, EF). This study involved a comprehensive investigation of EF in this population taking into account the contributions of age, nonverbal IQ and verbal ability. Methods: Ten separate measures of EF were assessed in 160 children: 41 had SLI; 31 had low language/cognitive functioning but did not fulfil the criteria for SLI (low language functioning or LLF); and 88 were typically developing with no language difficulties. Group differences in performance were assessed after controlling for age, nonverbal IQ and verbal ability in a series of regression analyses. Results: Children with SLI and LLF had significantly lower performance than typical children on 6 of the 10 EF tasks once age and nonverbal IQ had been controlled (verbal and nonverbal executive-loaded working memory, verbal and nonverbal fluency, nonverbal inhibition and nonverbal planning). Performance on these EF tasks remained lower for those in the SLI group even when verbal IQ was entered in the regressions. Conclusions: Children with language impairments showed marked difficulties on a range of EF tasks. These difficulties were present even when adjustments were made for their verbal abilities.

Titre : Subgrouping school-aged children on the autism spectrum based on co-occurring psychiatric symptoms Type de document : Texte imprimé et/ou numérique Auteurs : Antonia M. H. PIERGIES, Auteur ; Tomoya HIROTA, Auteur ; Rei MONDEN, Auteur ; Shuting ZHENG, Auteur Article en page(s) : 101983 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Latent class analysis Co-occurring psychiatric symptoms Nonverbal IQ Atypical sleep duration Medical conditions Index. décimale : PER Périodiques Résumé : Background Phenotypic heterogeneity along the autism spectrum is compounded by co-occurring psychiatric conditions. Deriving subgroups of autistic individuals based on symptoms of these conditions could better our understanding of psychiatric symptom patterns existing within this population. This study?s goals were to derive subgroups of school-aged autistic children based on co-occurring psychiatric symptoms while controlling for age and sex and to examine correlates of subgroup membership while controlling for the degree of ASD-related diagnostic features. Method Latent class models were estimated in a sample from the Simons Simplex Collection (n = 2087) using ?borderline/clinical? versus ?normative? range data from five of the DSM-Oriented Scales from the CBCL/6?18 as indicator variables. We evaluated the predictive value of NVIQ < 70, atypical sleep duration, allergies/autoimmune conditions, gastrointestinal conditions, and neurological conditions on subgroup membership using multinomial logistic regression. Results Four subgroups emerged: Low Psychiatric Symptoms (41.02%), Externalizing Symptoms (12.36%), Internalizing Symptoms (31.58%), and High Psychiatric Symptoms (15.05%). Key findings were that NVIQ < 70 was associated with decreased odds of belonging to the Internalizing Symptoms and High Psychiatric Symptoms subgroups over the Low Psychiatric Symptoms subgroup, while atypical sleep duration and gastrointestinal conditions were associated with increased odds of belonging to the Externalizing Symptoms and High Psychiatric Symptoms subgroups. Neurological conditions were also associated with increased odds of belonging to the Externalizing Symptoms subgroup. Conclusion Distinct patterns of psychiatric symptoms exist within school-aged autistic children and are correlated with NVIQ < 70, atypical sleep duration, and medical conditions, providing insights for clinical practice and etiology-driven research.
