Methods: The initial validation sample was comprised of parents of 175 individuals with autism spectrum disorder (ASD) (35 females, 140 males; M age = 7.19 years, SD age = 3.96) and the replication sample consisted of 624 parents of children who were either typically developing or presented with a range of neurodevelopmental and neuropsychiatric disorders (302 females, 322 males; M age = 11.49 years, SDage = 4.48). Parents from both samples completed the SSDS and the Social Responsiveness Scale (SRS-2). Results: Exploratory Structural Equation Modeling indicated that a 5-factor model provided adequate to excellent fit to the data in the initial ASD sample (comparative fit index [CFI] = .940, Tucker-Lewis Index [TLI] = .919, root mean square error of approximation [RMSEA] = .048, standardized root mean square residual [SRMR] = .038). The identified factors were interpreted as Social Motivation, Social Affiliation, Expressive Social Communication, Social Recognition, and Unusual Approach. This factor structure was further confirmed in Sample 2 (CFI = 946, TLI = .930, RMSEA = .044, SRMR = .026). Internal consistency for all subscales was in the good to excellent range across both samples as indicated by Composite Reliability scores of >/= .72. Convergent and divergent validity was strong as indexed by the pattern of correlations with relevant SRS-2 and Child Behavior Checklist domains and with verbal and non-verbal intellectual functioning scores in Sample 1 and with the Need to Belong Scale and Child Social Preference Scale scores in Sample 2. Across both samples, females had higher social motivation and expressive social communication scores. Discriminant validity was strong given that across all SSDS subscales, the ASD sample had significantly higher impairment than both the typically developing group and the group with other clinical conditions, which in turn, had significantly higher impairment than the typically developing group. Conclusions: Our findings provide initial validation of a new scale designed to comprehensively capture individual differences in social motivation and other key social dimensions in ASD.

Exploring Social Subtypes in Autism Spectrum Disorder: A Preliminary Study / Mirko ULJAREVIC in Autism Research, 13-8 (August 2020)  

Public ISBD [article]  inAutism Research > 13-8 (August 2020) . - p.1335-1342 Titre : Exploring Social Subtypes in Autism Spectrum Disorder: A Preliminary Study Type de document : Texte imprimé et/ou numérique Auteurs : Mirko ULJAREVIC, Auteur ; Jennifer M.

LIBOVE, Auteur ; Thomas W FRAZIER, Auteur ; Antonio Y. HARDAN, Auteur Article en page(s) : p.1335-1342 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  individual differences  social motivation  social processing Index. décimale : PER Périodiques Résumé : Impairments in social functioning are considered a hallmark diagnostic feature of autism spectrum disorder (ASD). Yet, individuals diagnosed with ASD vary widely with respect to specific presentation, severity, and course across different dimensions of this complex symptom domain. The aim of this investigation was to utilize the Stanford Social Dimensions Scale (SSDS), a newly developed quantitative measure providing parental perspective on their child's social abilities, in order to explore the existence of homogeneous subgroups of ASD individuals who share unique profiles across specific dimensions of the social domain. Parents of 164 individuals with ASD (35 females, 129 males; mean(age) = 7.54?years, SD = 3.85) completed the SSDS, the Social Responsiveness Scale (SRS-2) and the Child Behavior Checklist (CBCL). Data on children's verbal and nonverbal intellectual functioning (FSIQ) were also collected. The Latent Profile Analysis was used to classify participants according to the pattern of SSDS subscale scores (Social Motivation, Social Affiliation, Expressive Social Communication, Social Recognition, and Unusual Approach). Five profiles were identified. Profiles did not differ in terms of chronological age nor gender distribution but showed distinct patterns of strengths and weaknesses across different social components rather than simply reflecting a severity gradient. Profiles were further differentiated in terms of cognitive ability, as well as ASD and internalizing symptom severity. The implications of current findings and the necessary further steps toward identifying subgroups of individuals with ASD who share particular constellation of strengths and weaknesses across key social domains as a way of informing personalized interventions are discussed.

LAY SUMMARY: People with autism spectrum disorder (ASD) vary greatly in terms of their social abilities and social motivation. However, researchers lack measures that can fully assess different components of social functioning. This paper provides initial evidence for capturing subgroups of individuals with ASD with specific strengths and weakness across different aspects of social functioning.
