Et si le Quotient du spectre de l'autisme se composait de deux sous-groupes différents? Analyse en grappes du Quotient du spectre autistique dans la population générale.

Aperçu: G.M.

Le but de cette étude était d'étudier si les personnes dans la population générale ayant des scores élevés sur le Quotient du spectre de l'autisme constituaient un seul groupe homogène ou non. Sur la base des résultats de l'analyse, les élèves pourraient être divisés en six groupes. Les résultats de cette étude ont suggéré que les personnes dans la population générale avec des scores élevés au quotient de spectre de l'autisme peuvent se composer de deux groupes qualitativement différents.

Abstract

The purpose of this study was to investigate whether the individuals in the general population with high scores on the Autism Spectrum Quotient constituted a single homogeneous group or not. A cohort of university students (n = 4901) was investigated by cluster analysis based on the original five subscales of the Autism Spectrum Quotient. Based on the results of the analysis, the students could be divided into six clusters: the first with low scores on all the five subscales, the second with high scores on only the 'attention to detail' subscale, the third and fourth with intermediate scores on all the subscales, the fifth with high scores on four of the five subscales but low scores on the 'attention to detail' subscale and the sixth with high scores on all the five subscales. The students with high total Autism Spectrum Quotient scores (n = 166) were divided into two groups: one with high scores on four subscales but low scores on the 'attention to detail' subscale and the other with high scores on all the five subscales. The results of this study suggested that individuals from the general population with high Autism Spectrum Quotient scores may consist of two qualitatively different groups.
