The Latent Structure of Autistic Traits: A Taxometric, Latent Class and Latent Profile Analysis of the Adult Autism Spectrum Quotient / Richard J.E. JAMES in Journal of Autism and Developmental Disorders, 46-12 (December 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-12 (December 2016) . - p.3712-3728 Titre : The Latent Structure of Autistic Traits: A Taxometric, Latent Class and Latent Profile Analysis of the Adult Autism Spectrum Quotient Type de document : texte imprimé Auteurs : Richard J.E. JAMES, Auteur ; Indu DUBEY, Auteur ; Danielle SMITH, Auteur ; Danielle ROPAR, Auteur ; Richard J. TUNNEY, Auteur Article en page(s) : p.3712-3728 Langues : Anglais (eng) Mots-clés : Autism quotient  Autistic traits  Taxometric analysis  Latent class analysis  Latent structure analysis  Nosology Index. décimale : PER Périodiques Résumé : Autistic traits are widely thought to operate along a continuum. A taxometric analysis of Adult Autism Spectrum Quotient data was conducted to test this assumption, finding little support but identifying a high severity taxon. To understand this further, latent class and latent profile models were estimated that indicated the presence of six distinct subtypes: one with little probability of endorsing any autistic traits, one engaging in ‘systemising’ behaviours, three groups endorsing multiple components of Wing and Gould’s autistic triad, and a group similar in size and profile to the taxon previously identified. These analyses suggest the AQ (and potentially by extension autistic traits) have a categorical structure. These findings have important implications for the analysis and interpretation of AQ data.
