There is consensus that neurological differences are present in ASD. Further, theories emphasize the mixture of hypo- and hyper-connectivity as a neuropathologies in ASD [O'Reilly, Lewis, & Elsabbagh, 2017]; however, there is a paucity of studies specifically testing neurological underpinnings as predictors of success on social skills interventions. This study examined functional neural connectivity (electroencephalogram [EEG], coherence) of adolescents with ASD before and after the Program for the Education and Enrichment of Relational Skills (PEERS®) intervention, using a randomized controlled trial of two groups: an Experimental ASD (EXP) Group and a Waitlist Control ASD (WL) Group. The study had two purposes. First, the study aimed to determine whether changes in EEG coherence differed for adolescents that received PEERS® versus those that did not receive PEERS®. Results revealed a significant increase in connectivity in the occipital left to temporal left pair for the EXP group after intervention. Second, the study aimed to determine if changes in EEG coherence related to changes in behavior, friendships, and social skills measured by questionnaires. At post-intervention, results indicated: (a) positive change in frontal right to parietal right coherence was linked to an increase in social skills scores; and (b) positive changes in occipital right to temporal right coherence and occipital left to parietal left coherence were linked to an increase in the total number of get-togethers. Results of this study support utilizing neurobehavioral domains as indicators of treatment outcome. Lay Summary: This study examined how well various areas of the brain communicate in adolescents with ASD before and after a social skills intervention. Results revealed increased connectivity in the adolescents that received the intervention. Secondly, the study aimed to determine if changes in connectivity of brain areas related to changes in behavior, friendships, and social skills. Results indicated that changes in connectivity were also linked to increased social skills. Autism Res 2021, 14: 787-803. © 2021 International Society for Autism Research and Wiley Periodicals LLC.

Differential Item Functioning Based on Autism Features, IQ, and Age on the Screen for Child Anxiety Related Disorders (SCARED) Among Youth on the Autism Spectrum / Hillary K. SCHILTZ in Autism Research, 14-6 (June 2021)  

Public ISBD [article]  inAutism Research > 14-6 (June 2021) . - p.1220-1236 Titre : Differential Item Functioning Based on Autism Features, IQ, and Age on the Screen for Child Anxiety Related Disorders (SCARED) Among Youth on the Autism Spectrum Type de document : texte imprimé Auteurs : Hillary K.

Moreover, few studies have examined the psychometric properties of anxiety measures in this population, and no study to date has tested whether there are systematic differences in the measurement of anxiety, or differential item functioning (DIF), across the high degree of heterogeneity and the developmental course of autism. To test this possibility, data were combined across multiple studies using the National Database for Autism Research, an NIH-funded data repository. Parent-report on the Screen for Child Anxiety Related Disorders (SCARED) and Social Communication Questionnaire (SCQ) were used as measures of anxiety and autism features, respectively. A confirmatory factor analysis indicated good fit of the literature standard five-factor structure. Moderated nonlinear factor analysis (MNLFA) revealed multiple items with intercept and loading DIF based on level of autism features, IQ, and age, especially for items related to social behavior. Therefore, although the measure's factor structure is consistent with that found in the general population, the SCARED may not capture differences in anxiety equivalently for all children on the spectrum and across their development. Clinicians and researchers need to be especially vigilant in measuring anxiety symptoms in children with autism by removing items flagged for DIF from the SCARED and/or by using multiple measures and informants. LAY ABSTRACT: Autistic youth often experience clinical levels of anxiety. Many tools used to measure anxiety were developed for the general population, but not for use with autistic youth. This study found that the Screen for Child Anxiety Related Disorders (SCARED) measures the same five dimensions of anxiety as in the general population. Parents, however, may respond differently to questions on the SCARED based on their child's autism features, intellectual functioning, and age, which impacts our ability to accurately measure anxiety among autistic youth.

The current study analyzed self-report data from 77 parents of youth with ASD. A serial multiple mediation model revealed that parenting stress (SIPA) and parental mental health (BAI and BDI-II) appears to be impacted by challenging adolescent behaviors (SSIS-PBs) and, in turn, affect parental involvement (PRQ), controlling for social skills (SSIS-SSs). Further, the study explored the malleability of parents' mental health over the course of a social skills intervention, and provides modest evidence that parent depressive symptoms decline across intervention. This study illustrates the importance of considering the entire family system in research on youth with ASD.

Gender-based differential item functioning on the child behavior checklist in youth on the autism spectrum: A brief report / Hillary K. SCHILTZ in Research in Autism Spectrum Disorders, 79 (November 2020)

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.

We examined the factor structure, reliability, and validity of a commonly-used measure of emotion dysregulation, the Difficulties with Emotion Regulation Scale (DERS), in a sample of 156 autistic adolescents and adults. Data were drawn from the NIH National Database for Autism Research (NDAR) and an author's existing dataset. Results demonstrated that the factor structure generally conformed to the original 6-factor model, with modifications. Reliability analyses revealed good-to-excellent internal consistencies. Validity analyses indicated that the DERS was positively associated with measures of anxiety, depression, and alexithymia. Our findings provide preliminary evidence for the utility of the DERS in a small autistic sample, with minor modifications.
