Public ISBD [article]  inAutism Research > 11-8 (August 2018) . - p.1148-1156 Titre : Executive function predicts the visuospatial working memory in autism spectrum disorder and attention-deficit/hyperactivity disorder Type de document : Texte imprimé et/ou numérique Auteurs : Z.

JIN, Auteur Article en page(s) : p.1148-1156 Langues : Anglais (eng) Mots-clés : attention-deficit/hyperactivity disorder  autism spectrum disorder  executive function  visuospatial working memory Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorder (ASD) and those with attention deficit/hyperactivity disorder (ADHD) always show working memory deficits. However, research findings on the factors that affected the working memory in ASD and ADHD were inconsistent. Thus, we developed the present study to investigate the association of executive function (EF) with the visuospatial working memory (VSWM) in ASD and ADHD. Three groups of participants were examined: 21 children with ASD, 28 children with ADHD and 28 typically developing (TD) children as the controls. All participants completed two tests: the Wisconsin Card Sorting Test (WCST) and the Corsi Block Tapping Test for measuring EF and VSWM, respectively. The WCST included four domains: categories achieved (CA), perseverative errors (PE), failures to maintain set (FMS), and total errors (TE). The findings indicated that (1) the ASD group showed poorer performance in VSWM than the ADHD and TD groups; (2) for the ASD group, VSWM was positively correlated with CA, and was negatively correlated with PE and TE; (3) for the ADHD group, FMS showed a negative relationship with VSWM; and (4) TE predicted the performance of VSWM in ASD group, while FMS predicted VSWM in ADHD group. The study results suggested that VSWM was impaired in ASD but not in ADHD. Also, the EF domains were differently correlated with the VSWM performance in ASD and ADHD. Our study suggests that we should consider different intervention targets of working memory and EF contributions in improving the cognitive capacity of ASD and ADHD. Autism Res 2018, 11: 1148-1156. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The present study compared the visuospatial working memory (VSWM) in three groups of children: autism (ASD), attention deficit/hyperactivity disorder (ADHD), and typically developed children (TD). The ASD group showed poorer VSWM than the ADHD and TD groups. The total error of executive function predicted the performance of VSWM in ASD, while failures to maintain set predicted VSWM in ADHD . These findings suggested that we should consider the different working memory and executive function training targets to increase cognitive capacity of ASD and ADHD.

Gender Difference in the Association Between Executive Function and Autistic Traits in Typically Developing Children / M. DAI in Journal of Autism and Developmental Disorders, 49-3 (March 2019)

The children were divided into the high- autistic-trait (HAT) and low-autistic-trait (LAT) groups based on their total autistic traits. Results suggested that there were gender differences in specific autistic traits in children with LAT. There were gender-specific associations between EF and autistic traits in children with HAT: the set shifting of EF predicted difficulties in social awareness in boys; whereas all the EF components predicted difficulties in social communication and social cognition in girls. These findings may have implications for developing customized interventions that are targeted at specific autistic deficits in males and females.

Psychometric properties of the chinese version of autism spectrum quotient-children's version: A sex-specific analysis / F. SUN in Autism Research, 12-2 (February 2019)  

Public ISBD [article]  inAutism Research > 12-2 (February 2019) . - p.303-315 Titre : Psychometric properties of the chinese version of autism spectrum quotient-children's version: A sex-specific analysis Type de document : Texte imprimé et/ou numérique Auteurs : F.

JING, Auteur Article en page(s) : p.303-315 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  autism-spectrum quotient  autistic traits  children  sex differences Index. décimale : PER Périodiques Résumé : A Simplified Chinese translation of the Autism Spectrum Quotient-Children's Version (AQ-C) is needed for research in mainland China. Autism Spectrum Disorder (ASD) is a condition that differs in presentation and prevalence by sex. Thus, evaluating the psychometric validity of the AQ-C in males and females is an important step in its validation. The present study aims to develop a Chinese translation of the parent-report AQ-C, and test its psychometric properties among Mandarin Chinese speaking boys and girls. A total of 1,020 non-clinical children and 134 children with ASD were assessed. Factor analyses were performed for the whole sample, as well as for girls and boys separately. A 30-item, 5-factor model (the Chinese AQ-C) showed adequate goodness of fit (root mean square error of approximation [RMSEA] = 0.037; comparative fit index [CFI] = 0.907; Tucker-Lewis index [TLI] = 0.901) for the whole sample. According to parents' reports, non-clinical boys had significantly higher scores than non-clinical girls on the Chinese AQ-C. Sex-specific factor structures were identified resulting in a 4-factor model with 32 items for girls (the Chinese AQ-Girls), and a 4-factor model with 34 items for boys (the Chinese AQ-Boys). The cut-off scores of the Chinese AQ-C, AQ-Girls, and AQ-Boys were 44.5, 42.5, and 46.5, respectively. These three Chinese versions of the AQ-C all showed satisfactory internal consistency (alpha = 0.786-0.840) and concurrent validity with the Social Responsiveness Scale (r = 0.789-0.814) for the total scale. Differences have been found in the sex-specific factor structures of the AQ-C which would be more reliable to use for future research when measuring autistic traits in the general population.

LAY SUMMARY: This study developed Chinese versions of the Autism Spectrum Quotient-Children's Version (AQ-C) in Chinese boys and girls together and separately.

To improve the situation, the Chinese version of the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) was validated. The sample included 7928 toddlers, aged 16 to 30 months, screened during their routine care in six provinces of China. When the cut-off value was 3, the sensitivity and specificity of M-CHAT-R were 0.963 and 0.865.
