The latent structure of the Delis-Kaplan system for autism / Reilly MACDONALD in Autism Research, 17-4 (April 2024)
[article]
Titre : The latent structure of the Delis-Kaplan system for autism Type de document : Texte imprimé et/ou numérique Auteurs : Reilly MACDONALD, Auteur ; Mary BAKER-ERICZEN, Auteur ; Scott ROESCH, Auteur ; May YEH, Auteur ; Kelsey S. DICKSON, Auteur ; Jasmine SMITH, Auteur Article en page(s) : p.728-738 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract A core feature of autism is deficits in executive functioning (EF), including difficulty with planning, cognitive flexibility, and working memory. Despite a growing need for evidence-based assessments of EF for autism populations, statistical models of many commonly used measures of EF, including the Delis-Kaplan Executive Function System (D-KEFS), have not been investigated for a sample of autistic participants. The purpose of this study was to address a gap in the literature regarding the latent structure of the D-KEFS in a sample of autistic individuals. The D-KEFS is one of the most widely used clinical assessments of executive function, but its factor structure has not been examined in a sample of autistic participants. Reliability analyses were performed for sample subgroups based on participants' clinical and demographic characteristics, including IQ, autism severity, age, and race/ethnicity. Verbal Fluency (VF) was found to consistently decrease or not affect the overall reliability score. Additionally, one- and two-factor structure models were tested for the D-KEFS with a sample of autistic participants. The one-factor model was not found to be a good fit for the data. However, the two-factor model, with Cognitive Flexibility and Abstraction latent factors, was found to fit the data relatively well. This two-factor model was reexamined excluding the VF observed variable, resulting in a better overall model fit. Communication deficits are a common feature of autism, which explains why the VF task, that requires participants to produce novel words, may not be an adequate measure of executive function for autism populations.
