However, it is not clear if there is a specific group of dysbiotic bacteria in ASD. The aim of this study was to carry out a meta-analysis on the studies that analyze GM in children with ASD. 18 studies fulfilled our selection criteria. Our results showed a lower relative abundance of Streptococcus (SMD(+) = - 0.999; 95% CI - 1.549, - 0.449) and Bifidobacterium genera (SMD(+) = - 0.513; 95% CI - 0.953, - 0.073) in children with ASD. Overall, the Bifidobacterium genera is involved. However, differences found between studies are attributed to factors such as reporting bias.

Relationships Between Emotion Regulation, Social Communication and Repetitive Behaviors in Autism Spectrum Disorder / Agustin E. MARTINEZ-GONZALEZ in Journal of Autism and Developmental Disorders, 52-10 (October 2022)

Author Jose A.  Piqueras declares that he has no conflict of interest. Index. décimale : PER Périodiques Résumé : The relationship between emotion regulation, social interaction and different types of restricted and repetitive behaviors is poorly understood. In the present study, structural equation modeling based on information about 239 individuals with autism was used to examine whether emotion regulation and social communication were associated with self-injury and stereotyped behaviors. Results showed that poor emotion regulation had a unique association with self-injury while difficulties with social communication was uniquely associated with stereotyped behaviors. Emotion regulation and social communication were strongly associated and self-injury and stereotyped behaviors moderately associated. This implies that these types of behaviors are often expressions of broader negative emotional states in autism. Treatments that help improve coping and social communication strategies may benefit individuals with autism.

Validation of the Repetitive Behavior Scale-Revised in Spanish-Speakers Participants with Autism Spectrum Disorder / Agustin E. MARTINEZ-GONZALEZ in Journal of Autism and Developmental Disorders, 48-1 (January 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-1 (January 2018) . - p.198-208 Titre : Validation of the Repetitive Behavior Scale-Revised in Spanish-Speakers Participants with Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Agustin E. MARTINEZ-GONZALEZ, Auteur ; Jose A. PIQUERAS, Auteur Article en page(s) : p.198-208 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Factor structure  Reliability  Repetitive behavior  Validity Index. décimale : PER Périodiques Résumé : Restricted and repetitive behavior (RRB) is one of the two key diagnostic features of autism spectrum disorder (ASD). DSM-5 highlights the importance of severity-based diagnostic modifiers assigned on the basis of intensity of needed supports. Therefore, there is a need for available measures that assess the severity of RRB. The repetitive behavior scale-revised (RBS-R) is probably the most used informant-based rating scale for the assessment of RRB and interests observed in ASD. The present study examined the psychometric properties of the Spanish version of the RBS-R in a sample of 233 participants with ASD, aged 3 to 63 years. Results revealed a six-factor model, good internal consistency, and concurrent-divergent validity. These findings suggest the utility of the Spanish version of RBS-R.
