Aperçu: G.M.
L'étude a examiné
les voies directes et indirectes impliquant le vocabulaire réceptif et
la diversité des consonnes clés utilisées dans la communication (DKCC)
pour mieux comprendre pourquoi les prédicteurs de valeur ajoutée
précédemment identifiés sont associés au vocabulaire expressif ultérieur
chez les enfants initialement pré-verbaux avec un diagnostic de trouble du spectre de l'autisme.
DKCC a dirigé l'association entre la communication intentionnelle et le vocabulaire expressif. Des recherches supplémentaires sont nécessaires pour reproduire les
résultats, tester les relations potentiellement causales et fournir une
séquence spécifique de cibles d'intervention pour les enfants
pré-verbaux avec un diagnostic de TSA.

Abstract
We
examined direct and indirect paths involving receptive vocabulary and
diversity of key consonants used in communication (DKCC) to improve
understanding of why previously identified value-added predictors are
associated with later expressive vocabulary for initially preverbal
children with autism spectrum disorder
(ASD; n = 87). Intentional communication, DKCC, and parent linguistic
responses accounted for unique variance in later expressive vocabulary
when controlling for mid-point receptive vocabulary, but responding to
joint attention did not. We did not confirm any indirect paths through
mid-point receptive vocabulary. DKCC mediated the association between
intentional communication and expressive vocabulary. Further research is
needed to replicate the findings, test potentially causal relations,
and provide a specific sequence of intervention targets for preverbal
children with ASD.
