Comparaison de la structure du facteur et de l'invariance de mesure de la version parentale de l'échelle d'anxiété Spence Children's Anxiety chez les enfants avec un diagnostic de trouble du spectre de l'autisme et chez des enfants anxieux se développant typiquement

Aperçu: G.M.

La version parentale du Spence Children's Anxiety Scale (SCAS-P) est souvent utilisée pour évaluer l'anxiété chez les enfants avec un diagnostic de trouble du spectre de l'autisme (TSA), mais on sait peu de choses sur la validité de l'outil dans cette population. 

Les résultats suggèrent que les comparaisons entre groupes entre les échantillons TSA et  anxieux basés sur les scores SCAS-P peuvent ne pas être toujours appropriés.

Abstract

The Spence Children's Anxiety Scale-Parent version (SCAS-P) is often used to assess anxiety in children with autism spectrum disorder (ASD), however, little is known about the validity of the tool in this population. The aim of this study was to determine whether the SCAS-P has the same factorial validity in a sample of young people with ASD (n = 285), compared to a sample of typically developing young people with anxiety disorders (n = 224). Poor model fit with all of the six hypothesised models precluded invariance testing. Exploratory factor analysis indicated that different anxiety phenomenology characterises the two samples. The findings suggest that cross-group comparisons between ASD and anxious samples based on the SCAS-P scores may not always be appropriate.
