Prior research has established that individuals with autism may be more likely than individuals who are not autistic to have repetitive thoughts. It is possible that persistent thoughts about negative or distressing stimuli may contribute to emotion dysregulation in autism spectrum disorder. This study aimed to identify areas of the brain with evidence of persistent processing of negative information via functional magnetic resonance neuroimaging. We used a task that alternated between emotional processing of personally relevant negative words, neutral words, and a non-emotional task. Criteria were developed to define heightened and persistent emotional processing, and analyses were conducted to identify all brain regions satisfying these criteria. Participants included 25 adolescents with autism spectrum disorder and 23 typically developing adolescents who were similar to the autism spectrum disorder group in IQ, age, and gender ratios. Brain regions identified as having greater and continued processing following negative stimuli in the autism spectrum disorder group as compared with the typically developing group included the salience network and the prefrontal dorsolateral cortex. These areas have been previously implicated in emotion dysregulation outside of autism spectrum disorder. Collectively, brain activity in the identified regions was associated with parent-reported emotion dysregulation in the autism spectrum disorder group. These results help to identify a potential process in the brain associated with emotion dysregulation in autism spectrum disorder. This information may be useful for the development of treatments to decrease emotion dysregulation in autism spectrum disorder.

The relationship between peer victimization and the psychological characteristics of youth with autism spectrum disorder / Danielle UNG in Research in Autism Spectrum Disorders, 32 (December 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 32 (December 2016) . - p.70-79 Titre : The relationship between peer victimization and the psychological characteristics of youth with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Danielle UNG, Auteur ; Nicole MCBRIDE, Auteur ; Amanda COLLIER, Auteur ; Robert SELLES, Auteur ; Brent SMALL, Auteur ; Vicky PHARES, Auteur ; Eric STORCH, Auteur Article en page(s) : p.70-79 Langues : Anglais (eng) Mots-clés : Victimization  Bullying  Autism  Social support  Anxiety  Depression  Loneliness Index. décimale : PER Périodiques Résumé : AbstractBackground Youth with autism spectrum disorder (ASD) are frequently victimized. Acts of peer victimization of youth with ASD can lead to the development of detrimental and maladaptive behavioral problems. The purpose of this study is to examine the relationship between peer victimization and the psychological characteristics of youth with ASD. Method Study participants were 81 school-aged youth with ASD between the ages of 9 and 17 years and had an intelligence quotient (IQ) ? 70 and their parents. Participants completed questionnaires examining the frequency of peer victimization and clinical characteristics of the youth. Results Victimization had a significant positive relationship with child’s loneliness and anxiety and depressive symptoms, and a significant negative relationship with social skills. The relationship between victimization and these symptoms did not significantly vary as a function of social support. The relationship between victimization and social avoidance was not mediated by a fear of negative evaluation. Conclusions These results may assist in identifying risk factors for peer victimization in youth with ASD and may help to shape treatment protocols by targeting the associated factors of peer victimization (e.g., anxiety and depressive symptoms, social skill deficits).
