Trajectories of co-occurring psychopathology symptoms in autism from late childhood to adulthood / James B. MCCAULEY in Development and Psychopathology, 32-4 (October 2020)
[article]
Titre : Trajectories of co-occurring psychopathology symptoms in autism from late childhood to adulthood Type de document : Texte imprimé et/ou numérique Auteurs : James B. MCCAULEY, Auteur ; Rebecca ELIAS, Auteur ; Catherine LORD, Auteur Article en page(s) : p.1287-1302 Langues : Anglais (eng) Mots-clés : autism co-occurring symptoms development longitudinal data outcomes trajectories Index. décimale : PER Périodiques Résumé : Given high rates of co-occurring conditions in youth and adults with autism spectrum disorder (ASD), it is critical to examine the developmental trajectories of these symptoms of psychopathology. Using data from a cohort of participants (n = 194), most of whom were first assessed for ASD in very early childhood, we investigated the trajectories of co-occurring depressive, anxiety, and attention-deficit hyperactivity disorder (ADHD) symptoms from late childhood to adulthood. Additionally, childhood predictors and adult outcomes associated with these symptom trajectories were examined. Using group-based trajectory modeling, we found two distinct classes of individuals exhibiting each of these co-occurring symptom patterns: one class exhibited fairly low symptoms across time, and one class with elevated symptoms with varied fluctuation across time (ADHD symptoms starting high but decreasing, anxiety symptoms high and stable, and depressive symptoms fluctuating but peaking at clinically significant levels in young adulthood). All high trajectory classes were associated with age 9 adaptive skills; verbal IQ predicted higher anxiety and depressive symptom classes. After accounting for verbal IQ, all high symptom trajectory classes were negative predictors of objective adult outcomes. These findings call for wide-ranging considerations of the needs of individuals across ability levels, autism symptoms, and behavioral and emotional challenges.

Titre : Gender-based differential item functioning on the child behavior checklist in youth on the autism spectrum: A brief report Type de document : Texte imprimé et/ou numérique Auteurs : Hillary K. SCHILTZ, Auteur ; Brooke E. MAGNUS, Auteur Article en page(s) : 101669 Langues : Anglais (eng) Mots-clés : Differential item Functioning Autism Co-occurring symptoms Child behavior checklist Females Gender Index. décimale : PER Périodiques Résumé : Background Given the call for gender-informed autism research (Mandy & Lai, 2017), understanding the presentation and measurement of commonly co-occurring behavioral and emotional concerns among males and females on the autism spectrum is paramount. The validity of conclusions in this area of research necessitates that questionnaires capture true differences in constructs rather than systematic gender-based differences in measurement, an assumption which may be violated due to differential item functioning (DIF). Method In the present study, caregiver-report data on the Child Behavior Checklist (CBCL) (N = 502) were gathered across multiple studies from the National Database for Autism Research (NDAR), an NIH-funded data repository. Results Confirmatory factor analysis initially revealed poor to acceptable fit across subscales, suggesting a lack of unidimensionality. Fit was acceptable on all subscales following modifications for low factor loadings or highly correlated residuals. Multiple indicator multiple cause (MIMIC) models indicated that the majority of items did not show substantial DIF, with no items flagged for gender-based DIF on the Attention Problems, Withdrawn/Depressed, and Somatic Problems subscales. Items were flagged for gender-based DIF, however, on the Social Problems, Anxious/ Depressed, Aggressive Behavior, and Thought Problems subscales. Conclusions These findings indicate that few items on a measure of emotional and behavioral problems (Child Behavior Checklist; CBCL) function differently for male and female youth on the autism spectrum. This study has implications for future autism research aiming to accurately capture co-occurring emotional or behavioral problems and examine the etiology, trajectory, and ultimately treatment for males and females on the autism spectrum.
