Are the Autism and Positive Schizotypy Spectra Diametrically Opposed in Empathizing and Systemizing? / Suzanna N. RUSSELL-SMITH in Journal of Autism and Developmental Disorders, 43-3 (March 2013)

The current study aimed to further assess the validity of this theory by investigating predictions in relation to empathizing and systemizing. Specifically, it is predicted by Crespi and Badcock that while mild autistic traits should be associated with a cognitive profile of superior mechanistic cognition (which overlaps with systemizing) but reduced mentalistic cognition (which overlaps with empathizing), positive schizotypy traits should be associated with the opposite profile of superior mentalistic but reduced mechanistic cognition. These predictions were tested in a student sample using a battery of self-report and behavioural measures. The pattern of results obtained provides no support for Crespi and Badcock’s theory.

Their specific claim that autistic and positive schizophrenia traits contrastingly affect preference for local versus global processing was investigated by examining Embedded Figures Test performance in two groups of students separated on autistic-like traits but matched on positive schizotypy traits, and two groups separated on positive schizotypy traits but matched on autistic-like traits (n = 20 per group). Consistent with their theory, higher levels of autistic-like traits were associated with faster identification of hidden figures, whereas higher levels of positive schizotypy traits were associated with slower identification.

Are there differences in the behavioural phenotypes of Autism Spectrum Disorder probands from simplex and multiplex families? / Lauren J. TAYLOR in Research in Autism Spectrum Disorders, 11 (March 2015)

WHITEHOUSE, Auteur Article en page(s) : p.56-62 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Behavioural phenotype  Simplex and multiplex families Index. décimale : PER Périodiques Résumé : Recent research suggests that different genetic pathways may operate for families with one child affected with Autism Spectrum Disorder (simplex ASD), compared to families that have multiple affected children (multiplex ASD). In this study, we investigated possible differences in the behavioural phenotypes of probands from simplex and multiplex ASD families using parent-report and standardised behavioural measures. Participants were 59 probands from multiplex ASD families (28 families), who were each matched on chronological age and sex with two probands from simplex families. Probands from multiplex families had greater social impairment (measured using the Social Responsiveness Scale) and worse pragmatic language (on the Children's Communication Checklist-2) than probands from simplex families. However, the multiplex children had less severe symptoms than the simplex children on the ADOS-G, and a significantly higher proportion of multiplex children did not meet autism spectrum cut-offs on this measure. These findings indicate that there are behavioural differences in children with ASD from simplex and multiplex families. In addition, the results reveal an important discrepancy between parent-report and clinician observation of autistic-like characteristics in siblings of an affected child, which may have implications for the assessment and diagnosis of ASD.

Assessing Restricted and Repetitive Behaviours in Online-Sampled Autistic and Non-autistic Individuals: Factor Structure of the Repetitive Behaviours Questionnaire for Adults (RBQ-2A) / Jack D. BRETT in Journal of Autism and Developmental Disorders, 54-6 (June 2024)

MAYBERY, Auteur Article en page(s) : p.2138-2147 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The Repetitive Behaviours Questionnaire for Adults (RBQ-2A) measures two factors of restricted and repetitive behaviours (RRBs) associated with autism. However, the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) provides four criteria for RRBs: repetitive motor behaviours, insistence on sameness, restricted interests, and interest in sensory aspects of the environment (or atypical sensitivity). The current paper aimed to examine whether the RBQ-2A is a psychometrically sound measure of these four factors. Study 1 had university students (N = 368) complete the RBQ-2A and other related measures online and revealed that the RBQ-2A can assess the factors highlighted in the DSM-5 and that these four factors comprise a general RRB construct. Study 2 had individuals disclosing a diagnosis of autism (N = 283) complete the RBQ-2A and other related measures online and supported that this four-factor structure provided good psychometric properties. While the current paper provides findings for an online autistic population, further research is needed to generalize these findings to autistic individuals less likely to partake in online studies (e.g., those with intellectual or language disabilities). Overall, the results suggest that the RBQ-2A reliably and validly assesses RRBs.
