Résumé

La décision de regrouper plusieurs troubles apparentés en un diagnostic unique de trouble du spectre de l'autisme (TSA) a suscité une controverse et un débat importants. Les données sont mitigées quant à savoir si les divers sous-types de TSA sont qualitativement distincts ou s'ils existent sur un spectre de sévérité des symptômes. La présente étude a réalisé une analyse en grappes en deux étapes des principaux symptômes de TSA dans un échantillon de 147 jeunes garçons atteints de TSA, âgés de 6 ans à 18 ans, avec un QI > 70. Les résultats ont indiqué qu'une solution à deux grappes (sévérité élevée et faible de la symptomatologie du TSA) était fiable et valide. En outre, le construit du comportement problématique n'était pas une composante nécessaire de la solution à deux grappes, confirmant la nouvelle conceptualisation du TSA. Une réplication supplémentaire de ces résultats auprès d'autres sous-groupes d'individus atteints de TSA est nécessaire.

The decision to collapse several related disorders into a single diagnosis of Autism Spectrum Disorder (ASD) generated significant controversy and debate. There has been mixed evidence as to whether various ASD subtypes are qualitatively distinct or if they exist on a spectrum of symptom severity. The present study conducted a two-step cluster analysis of major ASD symptoms in a sample of 147 young males with ASD aged between 6yr and 18yr with IQ > 70. Results indicated that a two-cluster solution (high and low severity of ASD symptomatology) was reliable and valid. Further, the construct of challenging behaviour was not a necessary component of the two-cluster solution, verifying the new conceptualisation of ASD. Further replication of these findings with other subsets of individuals with ASD is needed.

Vue d’ensemble de la bibliographie citée

Ces indicateurs décrivent la bibliographie citée par cette publication. Un nom d’auteurice est compté chaque fois qu’il apparaît dans une référence citée : une même personne peut donc être comptée plusieurs fois. Les noms qui ne sont pas encore associés à un·e auteurice déjà présent·e dans AutiHub sont traités comme inconnus, pas comme non autistes. Dernier calcul : 19/09/2026 01:01.
