Sex-based differences are observed in the core symptoms of ASD. This study investigated the patterns and stability of restricted and repetitive behaviors (RRBs) among Chinese children with ASD. For cross-sectional comparisons, researchers recruited 1760 male and 350 female participants whose ages ranged from 4 to 17?years. The Social Responsiveness Scale-2 (SRS-2) was used to measure the core symptoms of ASD. Compared with males, females exhibited lower severity and incidence rates of RRB both overall and at the symptom level. Furthermore, multigroup confirmatory factor analyses demonstrated that sex-related differences did not significantly affect the conceptualization of RRBs. An online follow-up study involving a subset of participants (166 males and 41 females) revealed that RRB symptoms remained stable between the two visits for males; however, only specific symptoms were highly consistent over time for females. This study revealed potential sex-related differences in RRBs among Chinese individuals with ASD and revealed sex-dependent variations in symptom-level presentation patterns and stability. These findings may contribute to a better understanding of the mechanisms underlying sex-related differences and aid in the development of sex-specific diagnostic criteria.

The Structure and Individual Patterns of Emotional and Behavioral Problems in Preschool Children With Autism Spectrum Disorder: Evidence From Network and Cluster Analyses / Lijing LIN in Autism Research, 19-9 (September 2026)  

Public ISBD [article]  inAutism Research > 19-9 (September 2026) . - p. e70343 Titre : The Structure and Individual Patterns of Emotional and Behavioral Problems in Preschool Children With Autism Spectrum Disorder: Evidence From Network and Cluster Analyses Type de document : texte imprimé Auteurs : Lijing LIN, Auteur ; Bingqian GAO, Auteur ; Yanting HOU, Auteur ; Wenwen HUANG, Auteur ; Xiaosong LI, Auteur ; Ling WANG, Auteur ; Yidong SHEN, Auteur ; Jianjun OU, Auteur Article en page(s) : p. e70343 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  cluster analysis  individual differences symptom networks  intervention target  symptom network comparison Index. décimale : PER Périodiques Résumé : ABSTRACT This study explored the interactions between emotional and behavioral symptoms in preschool children with autism spectrum disorder (ASD) and identified potential clinical subtypes based on these interrelationships. A total of 1886 preschool children with ASD and 285 age-matched typically developing (TD) children were assessed using the Child Behavior Checklist for ages 1.5?5. Symptom networks were estimated using the EBICglasso algorithm, and group differences were evaluated via network comparison tests. Subgroups within the ASD sample were identified using Individual Difference Symptom Networks (IDSN) with k-means clustering. The results revealed distinct network structures between the ASD and TD groups, with emotional reactivity demonstrating the highest centrality in the ASD network. Two distinct ASD subgroups (ASD-A and ASD-B) were identified, which showed significant differences from the TD group across all emotional and behavioral dimensionsin the CBCL 1.5?5. The subgroups differed significantly in overall network strength and specific edge connections, particularly between aggressive behavior and withdrawal problems. The findings indicate that emotional reactivity may play a central role in the symptom network of preschool children with ASD. The identification of two clinical subgroups with distinct symptom connectivity patterns provides valuable insights for developing more individualized and targeted intervention strategies. ASD-A subgroup points to the potential value of comprehensive early intervention programs, whereas ASD-B subgroup highlights the need for functional communication training and social engagement strategies.
