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 ULJAREVI? in Autism Research, 18-1 (January 2025)  

Public ISBD [article]  inAutism Research > 18-1 (January 2025) . - p.133-151 Titre : Exploring the Heterogeneity of Self-Injurious Behaviors in Autistic Youth: Patterns, Predictors, and Implications for Intervention : Autism Research Type de document : Texte imprimé et/ou numérique Auteurs : Emily F.

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.

Understanding the heterogeneity of anxiety in autistic youth: A person-centered approach / Emily SPACKMAN in Autism Research, 15-9 (September 2022)  

Public ISBD [article]  inAutism Research > 15-9 (September 2022) . - p.1742-1754 Titre : Understanding the heterogeneity of anxiety in autistic youth: A person-centered approach Type de document : Texte imprimé et/ou numérique Auteurs : Emily SPACKMAN, Auteur ; Jian Wei LERH, Auteur ; Jacqui RODGERS, Auteur ; Matthew J. HOLLOCKS, Auteur ; Mikle SOUTH, Auteur ; Helen MCCONACHIE, Auteur ; Ann OZSIVADJIAN, Auteur ; Amy VAUGHAN VAN HECKE, Auteur ; Robin LIBOVE, Auteur ; Antonio Y. HARDAN, Auteur ; Susan R. LEEKAM, Auteur ; Emily SIMONOFF, Auteur ; Thomas W. FRAZIER, Auteur ; Gail A. ALVARES, Auteur ; Jessica M. SCHWARTZMAN, Auteur ; Iliana MAGIATI, Auteur ; Mirko ULJAREVIĆ, Auteur Article en page(s) : p.1742-1754 Langues : Anglais (eng) Mots-clés : Adolescent  Anxiety/complications/psychology  Anxiety Disorders/psychology  Autism Spectrum Disorder/complications/epidemiology/psychology  Autistic Disorder  Child  Child Development Disorders, Pervasive  Child, Preschool  Female  Humans  anxiety  autism  individual differences  latent profile analysis  subtyping Index. décimale : PER Périodiques Résumé : The present study aimed to examine anxiety profiles among children and adolescents on the autism spectrum. It further aimed to characterize the association between the identified anxiety profiles and key clinical and developmental variables. The Spence Children's Anxiety Scale-Parent Version (SCAS-P) data from a large international pooled sample of 870 caregivers of autistic children and adolescents (M(age)  = 11.6years, SD(age)  = 2.77; 107 females) was used. Latent profile analysis identified a three-anxiety profile solution exhibiting high entropy (0.80) and high latent profile probabilities, with good classification accuracy. Identified profiles fell along the severity spectrum and were named as the mild (n = 498), moderate (n = 272) and severe (n= 100) anxiety profiles. There were no statistically significant differences between the three anxiety profiles in terms of sex distribution. Participants in the mild profile were significantly younger than those in the severe profile, had significantly fewer social communication difficulties than youth in the moderate anxiety profile group and had significantly fewer restricted and repetitive behaviors and lower cognitive functioning scores compared to participants in moderate and severe anxiety profiles. This is the first study to move beyond identifying associations and group-level differences to exploring and identifying characteristics of anxiety-based subgroups at an individual level that differ on key clinical and developmental variables. The subgroups identified in this study are a preliminary, yet important, first step towards informing future assessment and individualized interventions aiming to support young people on the autism spectrum to reduce and manage anxiety. LAY SUMMARY: This study tried to understand if there are subgroups of autistic young people who may have similar anxiety profiles. We found that we could meaningfully group young people into three groups based on how severe the anxiety symptoms their caregivers reported were: a group with low levels of anxiety, those with moderate anxiety, and those with more severe anxiety. We also found that the young people in the mild group were younger, had fewer autism traits and lower levels of intellectual functioning than young people in the other two groups.
