Consistency and reliability of automated language measures across expressive language samples in autism / Heather MACFARLANE in Autism Research, 16-4 (April 2023)
[article]
Titre : Consistency and reliability of automated language measures across expressive language samples in autism Type de document : Texte imprimé et/ou numérique Auteurs : Heather MACFARLANE, Auteur ; Alexandra C. SALEM, Auteur ; Steven BEDRICK, Auteur ; Jill K. DOLATA, Auteur ; Jack WIEDRICK, Auteur ; Grace O. LAWLEY, Auteur ; Lizbeth H. FINESTACK, Auteur ; Sara T. KOVER, Auteur ; Angela John THURMAN, Auteur ; Leonard ABBEDUTO, Auteur ; Eric FOMBONNE, Auteur Article en page(s) : p.802-816 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with substantial clinical heterogeneity, especially in language and communication ability. There is a need for validated language outcome measures that show sensitivity to true change for this population. We used Natural Language Processing to analyze expressive language transcripts of 64 highly-verbal children and young adults (age: 6-23?years, mean 12.8?years; 78.1% male) with ASD to examine the validity across language sampling context and test-retest reliability of six previously validated Automated Language Measures (ALMs), including Mean Length of Utterance in Morphemes, Number of Distinct Word Roots, C-units per minute, unintelligible proportion, um rate, and repetition proportion. Three expressive language samples were collected at baseline and again 4?weeks later. These samples comprised interview tasks from the Autism Diagnostic Observation Schedule (ADOS-2) Modules 3 and 4, a conversation task, and a narration task. The influence of language sampling context on each ALM was estimated using either generalized linear mixed-effects models or generalized linear models, adjusted for age, sex, and IQ. The 4?weeks test-retest reliability was evaluated using Lin's Concordance Correlation Coefficient (CCC). The three different sampling contexts were associated with significantly (P0.001) different distributions for each ALM. With one exception (repetition proportion), ALMs also showed good test-retest reliability (median CCC: 0.73-0.88) when measured within the same context. Taken in conjunction with our previous work establishing their construct validity, this study demonstrates further critical psychometric properties of ALMs and their promising potential as language outcome measures for ASD research.

LAWLEY, Auteur ; Steven BEDRICK, Auteur ; Heather MACFARLANE, Auteur ; Jill K. DOLATA, Auteur ; Alexandra C. SALEM, Auteur ; Eric FOMBONNE, Auteur Article en page(s) : p.2986-2997 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Pragmatic language difficulties, including unusual filler usage, are common among children with Autism Spectrum Disorder (ASD). This study investigated "um" and "uh" usage in children with ASD and typically developing (TD) controls. We analyzed transcribed Autism Diagnostic Observation Schedule (ADOS) sessions for 182 children (117 ASD, 65 TD), aged 4 to 15. Although the groups did not differ in "uh" usage, the ASD group used fewer "ums" than the TD group. This held true after controlling for age, sex, and IQ. Within ASD, social affect and pragmatic language scores did not predict filler usage; however, structural language scores predicted "um" usage. Lower "um" rates among children with ASD may reflect problems with planning or production rather than pragmatic language.
