Associations of age, anxiety, cognitive functioning, and social impairment with aggression in youth with autism / Ethan RINALDO in Research in Autism Spectrum Disorders, 108 (October 2023)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 108 (October 2023) . - p.102246 Titre : Associations of age, anxiety, cognitive functioning, and social impairment with aggression in youth with autism Type de document : Texte imprimé et/ou numérique Auteurs : Ethan RINALDO, Auteur ; Adrienne PERRY, Auteur Article en page(s) : p.102246 Mots-clés : Autism  Aggression  Anxiety  Social impairment  Cognitive functioning Index. décimale : PER Périodiques Résumé : Background Previous research has indicated that aggression in children with autism is associated with cognitive functioning, age, anxiety, and social functioning, although most samples only include parent-report measures and participants without intellectual disability. Furthermore, there is a lack of research investigating how different aspects of social impairment are associated with aggressive behaviour in youth with autism while anxiety is included in the analyses. The aim of this study was to clarify the relationships of these variables with aggression in a large sample, diverse in age and cognitive level, using both parent- and teacher-report measures. Method Participants were 1179 youth (age 4-18) with a diagnosis of autism spectrum disorder, from the SFARI database. Parent- and teacher-report measures were obtained for aggression, anxiety, and social impairment. Univariate statistics were calculated to determine how each variable was associated with aggression and hierarchical regressions were conducted with all variables together. Results Age and intellectual disability presence/severity had small positive relationships with teacher-measured aggression while anxiety and social impairment severity had strong relationships with aggression when rated by both parents and teachers. In a regression analysis, anxiety and social communication problems had the strongest positive relationships with aggression while social motivation problems had a negative relationship with aggression. Conclusion These results indicate the importance of anxiety and social problems, particularly in social communication and motivation, when studying and treating aggression in youth with autism.

Investigating language skills as a mediator between IQ and anxiety in autistic youth / Ethan RINALDO in Research in Autism Spectrum Disorders, 88 (October 2021)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 88 (October 2021) . - 101846 Titre : Investigating language skills as a mediator between IQ and anxiety in autistic youth Type de document : Texte imprimé et/ou numérique Auteurs : Ethan RINALDO, Auteur ; Evdokia ANAGNOSTOU, Auteur ; Stelios GEORGIADES, Auteur ; Muhammad AYUB, Auteur ; Robert NICOLSON, Auteur ; Elizabeth KELLEY, Auteur Article en page(s) : 101846 Langues : Anglais (eng) Mots-clés : Autism  Autism spectrum disorder  IQ  Language  Anxiety Index. décimale : PER Périodiques Résumé : Background Anxiety is a common condition noted to cause significant impairment in some autistic youth. Previous research has found that autistic youth tend to exhibit higher levels of traditional anxiety symptoms with higher IQ scores and higher language abilities. In this study of the relationship between anxiety, intelligence, and language skills in autistic youth, it was hypothesized that a mediational relationship would be observed in which IQ exerts its influence over anxiety through language skills. Method Participants consisted of 293 autistic youth between the ages of 7 and 18. Anxiety was assessed with the Revised Children’s Anxiety and Depression Scale, language with the Oral and Written Language Scales Version II, and IQ (performance, verbal, and full-scale) was measured with the Wechsler Abbreviated Scale of Intelligence Version II. A simple mediation model was used with IQ as the predictor variable, language as the mediator variable, and anxiety as the outcome variable. This analysis was conducted three times so that performance, verbal, and full-scale IQ could be examined as separate predictors. Results The results of this study confirmed our hypothesis with a full mediation effect for each IQ scale, although verbal IQ was too strongly correlated with language scores for it to be considered a separate construct from our language measure. Conclusions This model should inform further autism research in that the influence of IQ and language over anxiety should not be viewed as independent factors but as a set of constructs that exert a shared influence.
