Structural hierarchy of autism spectrum disorder symptoms: an integrative framework / Hyunsik KIM in Journal of Child Psychology and Psychiatry, 59-1 (January 2018)
[article]
Titre : Structural hierarchy of autism spectrum disorder symptoms: an integrative framework Type de document : Texte imprimé et/ou numérique Auteurs : Hyunsik KIM, Auteur ; Cara M. KEIFER, Auteur ; Craig RODRIGUEZ-SEIJAS, Auteur ; Nicholas R. EATON, Auteur ; Matthew D. LERNER, Auteur ; Kenneth D. GADOW, Auteur Article en page(s) : p.30-38 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder classification structural hierarchy Child and Adolescent Symptom Inventory bass-ackwards Index. décimale : PER Périodiques Résumé : Background In an attempt to resolve questions regarding the symptom classification of autism spectrum disorder (ASD), previous research generally aimed to demonstrate superiority of one model over another. Rather than adjudicating which model may be optimal, we propose an alternative approach that integrates competing models using Goldberg's bass-ackwards method, providing a comprehensive understanding of the underlying symptom structure of ASD. Methods The study sample comprised 3,825 individuals, consecutive referrals to a university hospital developmental disabilities specialty clinic or a child psychiatry outpatient clinic. This study analyzed DSM-IV-referenced ASD symptom statements from parent and teacher versions of the Child and Adolescent Symptom Inventory-4R. A series of exploratory structural equation models was conducted in order to produce interpretable latent factors that account for multivariate covariance. Results Results indicated that ASD symptoms were structured into an interpretable hierarchy across multiple informants. This hierarchy includes five levels; key features of ASD bifurcate into different constructs with increasing specificity. Conclusions This is the first study to examine an underlying structural hierarchy of ASD symptomatology using the bass-ackwards method. This hierarchy demonstrates how core features of ASD relate at differing levels of resolution, providing a model for conceptualizing ASD heterogeneity and a structure for integrating divergent theories of cognitive processes and behavioral features that define the disorder. These findings suggest that a more coherent and complete understanding of the structure of ASD symptoms may be reflected in a metastructure rather than at one level of resolution.

MAZEFSKY, Auteur ; R. J. WEBER, Auteur ; E. TRANSUE, Auteur ; M. SIEGEL, Auteur ; K. D. GADOW, Auteur Article en page(s) : p.3689-3701 Langues : Anglais (eng) Mots-clés : Autism inpatient collection Autism spectrum disorder (ASD) Child and Adolescent Symptom Inventory Minimally verbal Psychiatric comorbidity Verbal ability Index. décimale : PER Périodiques Résumé : Youth with autism spectrum disorder (ASD) experience high rates of psychiatric symptoms, but the relation between verbal ability and psychiatric symptoms is unknown. This study utilized a large sample of clinically referred inpatient and outpatient youth with ASD to compare psychiatric comorbidity between verbal and minimally-verbal youth, adjusting for nonverbal IQ, age, and ASD symptom severity. Results indicated that verbal youth were more likely to present with and meet clinical cutoffs for depression and oppositional defiant disorder symptoms, with greater impairment associated with depression. Youth in inpatient settings had greater symptom severity and impairment across almost all psychiatric comorbidities. These results present the most direct estimate to date of the association between verbal ability and psychiatric comorbidity in ASD.
