This study explored the interplay between developmental characteristics and emotion dysregulation, anxiety, and specific subtypes of RRBs that are elevated in autistic youth with co-occurring ID. Generalized additive models demonstrated that age, sex, language level, dysregulation, and anxiety showed unique patterns of association with subtypes of RRBs in a sample of 150 autistic youth with co-occurring ID who are non-speaking or minimally verbal. More specifically, higher anxiety levels were significantly associated with elevations in repetitive sensory motor behaviors (RSMB), self-injurious behaviors (SIB), insistence on sameness (IS), and unusual interests (UI). While emotion dysregulation was a significant predictor of UI, it demonstrated positive, albeit not significant, associations with the intensity of SIB and RSMB. Language level was a significant predictor of RSMB, such that the intensity of RSMB was higher for individuals who were non-speaking relative to those who spoke in single words. These findings provide preliminary insights into patterns of associations between emotion dysregulation, anxiety, and specific subdomains of RRBs in autistic youth with ID.

Exploring the Heterogeneity of Self-Injurious Behaviors in Autistic Youth: Patterns, Predictors, and Implications for Intervention / Emily F. FERGUSON ; Emily SPACKMAN ; Ru Ying CAI ; Antonio Y. HARDAN ; Mirko ULJAREVIĆ in Autism Research, 18-1 (January 2025)

Existing research on SIB in autism spectrum disorder (ASD) has been limited by significant methodological and conceptual inconsistencies. Thus, the current study leveraged item-level data capturing the severity of unique SIB topographies to further understanding of factors associated with distinct SIB in a sample of 582 autistic youth (Mage 12.12, SDage 3.68; range: 3 19 years; 13% females). Results suggest variation in severity endorsements for specific SIB topographies amongst autistic youth, such that 30% 50% of caregivers endorsed slight to very serious concern regarding the SIB topographies of bites nails/skin/fingers, scratches self, hits head/face/neck, bangs head against things, and picks skin. Generalized additive models demonstrated distinct patterns of associations between each SIB topography and dysregulation, sensory hypersensitivity, age, sex, IQ, and language level. Findings underscore the importance of exploring SIB as a multifaceted construct to capture unique correlates of distinct SIB that vary in severity and functional impact, which is critical for the development of effective interventions. This study represents an important step towards more individualized characterization of SIB and support for diverse presentations of these behaviors in autistic youth.

Factor Structure and Psychometric Properties of the Child Social Preference Scale-3 in Children With Autism / Antonio Y. HARDAN ; Emily SPACKMAN ; Emma K. BAKER ; Thomas W. FRAZIER ; Mirko ULJAREVIĆ in Autism Research, 18-7 (July 2025)

Since multiple processes may contribute to this heterogeneity, validating tools to assess these differences is crucial. Originally developed in the general population, the Child Social Preference Scale (CSPS-3) aims to assess distinct forms of social disengagement arising from different combinations of approach and avoidance motivations and holds promise for delineating variability in social behaviors within autism spectrum disorder (ASD). This study investigated the factor structure and psychometric properties of the CSPS-3 in a sample of 689 children diagnosed with autism (Mage 11.23, SD 3.56; 76% male). The results suggest that a bifactor model, consisting of a general factor and three subscales (shyness, unsociability, and social avoidance), provided the best fit to the data, with the general factor accounting for most of the variance. While the subscales demonstrated adequate internal consistency, their construct reliability and stability varied, with much of the reliable variance attributed to the general factor. The structure was consistent across age and sex subgroups, and the subscales showed distinct patterns of associations with key clinical correlates. These findings support the CSPS-3's utility in assessing diverse forms of social disengagement in the autism population, while indicating that the subscales could be refined to better capture their unique aspects.

Factor Structure of the Sleep Disturbance Scale for Children in a Cohort of Youth With Autism / Emma K. BAKER in Autism Research, 19-1 (January 2026)

HARDAN, Auteur ; Mirko ULJAREVIĆ, Auteur Article en page(s) : p.e70140 Langues : Anglais (eng) Mots-clés : assessment  autism  factor analysis  sleep Index. décimale : PER Périodiques Résumé : ABSTRACT Despite the substantial evidence base for poor sleep in autism, sleep problems are frequently under-identified and inefficiently managed. This is, in part, due to the fact that available tools do not comprehensively capture the specific sleep phenotypes in autism. The Sleep Disturbance Scale for Children (SDSC) is one of the highest ranked pediatric sleep assessment tools, yet it is scarcely used in autism research. Consequently, the utility of the SDSC for characterizing sleep disturbances in autism remains unknown. This study explored the factor structure of the SDSC in a sample of 513 autistic youth, aged 3?18?years (mean: 10.5?years; SD: 3.7; 18.7% female) drawn from the Healthy Brain Network secondary dataset. Fit of the previously derived SDSC factor structure was appraised using the confirmatory application of the exploratory structural equation modeling. Results indicated a five-factor solution comprising disorders of initiating and maintaining sleep, disorders of arousal, disorders of excessive somnolence (DoES), sleep breathing disorders, and sleep?wake transition disorders (SWTD) provided an excellent fit for the data. The derived factor solution was stable across sex and age. Notably, all sleep subscales were significantly positively associated with internalizing and externalizing behaviors, while age was significantly associated with DoES (r?=?0.15) and SWTD (r?=??0.18). This study provides the first validation of the SDSC in a large sample of well-characterized autistic youth showing distinct patterns of associations with key clinical correlates. Findings are consistent with independent reviews, suggesting the SDSC may provide a more effective way to screen for sleep disturbances in autistic individuals.
