Public ISBD [article]  inResearch in Autism Spectrum Disorders > 86 (August 2021) . - 101820 Titre : Criterion validity of the Autism Spectrum Rating Scales 2-5 parent report Type de document : texte imprimé Auteurs : Amy CAMODECA, Auteur ; Katy WALCOTT, Auteur Article en page(s) : 101820 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Parent report  Questionnaires  Criterion validity  Diagnostic utility Index. décimale : PER Périodiques Résumé : Background Questionnaires are frequently utilized in autism spectrum disorder (ASD) assessment and research, but there is limited evidence regarding their psychometric properties. Only two studies have investigated the diagnostic utility of the Autism Spectrum Rating Scale-2-5 parent report (ASRSp 2-5), and in both of these studies, the use of a gold-standard ASD measure in the diagnostic process is unclear. Method The current study investigated the criterion validity of the ASRSp-2-5 in a clinical sample of 238 children (X¯ age = 3.66; autism[AUT] n = 84; non-autism[NOT] n = 154). Children were diagnosed via a comprehensive assessment that included the Autism Diagnostic Observation Schedule-2. Results Analyses included t-tests/ANCOVAs, Logistic Regression (with and without covariates), and ROC analyses (with t-scores and predicted probabilities to account for covariates). The ASRSp 2-5 scores intended to be used for diagnosis (Total and DSM-5) were non-significant in all analyses. Higher scores in the NOT group were found for Unusual Behavior and Behavioral Rigidity. However, mean differences were non-significant with inclusion of control variables (IQ and age). Social, Peer Interaction, and Social-Emotional Reciprocity demonstrated the strongest findings. The ASD group had significantly higher scores on these scales, and findings held with covariates included (IQ for Social; age for Peer Interaction). However, odds ratios were small whether or not covariates were included, and AUCs were poor-fair (.69–.70). Sensitivity and specificity could not both be optimized at any cutpoint. Conclusions The findings were not as strong or as consistent as expected. Results suggest the ASRSp 2-5 is most useful in ruling out ASD in cases of low scores (<60). When the ASRSp 2-5 is utilized, behavioral, social, and emotional problems associated with other disorders must be considered in interpreting scores. Additional research on this measure is necessary.

Diagnostic Utility of the Gilliam Autism Rating Scales-3rd Edition Parent Report in Clinically Referred Children / Amy CAMODECA in Journal of Autism and Developmental Disorders, 53-5 (May 2023)

A comprehensive diagnostic evaluation, including the Autism Diagnostic Observation Schedule-2nd Edition (ADOS-2) was provided to 186 clinically referred children suspected of autism ($$\overline{X }$$age=8.98; Autism [AUT] n=87; Not Autism [NOT] n=99). Mean difference analyses, Logistic Regressions, and ROC analyses were non-significant for both Autism Index scores. The author-suggested cutoff score of 70 correctly classified approximately 47% of participants, with false positive rates=82.83-87.88%. ADOS-2 correlations were significantly lower vis-à-vis the standardization sample. The Social Interaction subscale demonstrated weak, marginal results, and sensitivity/specificity could not be optimized. In its current form, the GARS-3 does not demonstrate adequate criterion validity for use in assessment of complex community samples.

Factor Analysis of the Autism Spectrum Rating Scales Parent Report 6–18 in a Complex Community Sample / Amy CAMODECA in Journal of Autism and Developmental Disorders, 56-9 (September 2026)

This study investigated the factor structure of the Autism Spectrum Rating Scales-Parent report for ages 6–18 (ASRSp6) in a well-characterized community sample of 696 children (autism [AUT] n = 231; non-autism [NOT] n = 465; XÌ„age = 10.03) prospectively evaluated with the Autism Diagnostic Observation Schedule-2, a gold-standard autism diagnostic measure. The original author-identified structure demonstrated poor model fit. Exploratory Factor Analysis with a randomly selected half of the sample (n = 346) suggested retaining 17-items on three factors (Rigid/Sensory, Social, and Executive Function [EF]), explaining 55% of the variance. Confirmatory Factor Analysis with the remaining participants (n = 350) indicated good model fit. Partial measurement invariance was observed for diagnostic (AUT/NOT) and gender (male/female) groups. Correlations with the DSM-5p6 (an ASRSp6 scale) were high. Mean differences were observed between AUT/NOT groups for Social; when controlling for age, marginal differences (p = 0.02 − 0.03) were observed for all factors but EF. Social also demonstrated significant AUC regardless of control variables. However, AUC values for Social and other factors, while significant, were in the poor range; correlations with ADOS-2 scores were weak or non-significant. Despite improving the factor structure, the Total-17 does not appear to measure ASD-specific traits. However, these findings provide a basis for further research on ASD questionnaires.

Initial evidence for intact emotion fluency in autism vs. ADHD and community groups / Amy CAMODECA in Research in Autism, 123 (May 2025)  

Public ISBD [article]  inResearch in Autism > 123 (May 2025) . - 202565 Titre : Initial evidence for intact emotion fluency in autism vs. ADHD and community groups Type de document : texte imprimé Auteurs : Amy CAMODECA, Auteur Article en page(s) : 202565 Langues : Anglais (eng) Mots-clés : Autism  Emotion Word Fluency Test  Verbal Fluency  ADHD  Executive Function Index. décimale : PER Périodiques Résumé : Background The Emotion Word Fluency Test (EWFT) accounts for unique variance in Theory of Mind (ToM). As ToM weaknesses are observed in Autism Spectrum Disorder (ASD), it was hypothesized that an ASD group would demonstrate performance weakness on the EWFT. Method A community sample for EWFT comparison (COM, n = 113, X?age=10.43) was obtained from a University day camp and faculty/staff children. The clinical sample included 38 children with ASD (meanage=11.10) and 86 children with Attention-Deficit Hyperactivity Disorder (ADHD, meanage=9.89). EWFT and Animals was administered as part of a comprehensive evaluation. Results Analyses included EWFT-total and Animals-total (n-correct words in 60"), and the following EWFT scores: n-switches (changing between positive/negative emotions), n-clusters (groups of positive or negative emotions stated in order), and n-correct emotions in the first-15" and second-15" (automatically-accessed vs. strategically-accessed words, respectively). Controlling for age, no between-group differences mean differences were found for EWFT-total, n-switches, n-clusters, or second 15" interval.No within-subject differences between EWFT-total and Animals-total were observed. Autism Diagnostic Observation Schedule-2 scores were not significantly correlated with any EWFT/Animal scores. However, mediational analyses indicated that n-switches increased EWFT-total more efficiently for the COM vs. ASD/ADHD groups. Compared to the COM group, the ADHD group had a higher frequency of at least one EWFT set loss and generated fewer words in the first 15" interval of the EWFT. Conclusions This study provides initial evidence for intact emotion word fluency in ASD, and suggest switching is a differentially efficient emotion-word-generation strategy depending on group membership. This study provides a basis for additional research.

Theory of Mind Performance in Broad Autism Phenotype Groups: Between-Group Differences and Predictor Variables / Amy CAMODECA in Journal of Autism and Developmental Disorders, 49-10 (October 2019)

The BAP group (n = 45) performed worse than the Non-BAP group (n = 102) on the unexpected outcomes test (UOT), but groups were similar regarding reading the mind in the eyes test (RMET). Stepwise regression indicated RMET best predicted UOT for the BAP group; block design best predicted UOT in the Non-BAP group. BAP traits did not mediate the relation of RMET to UOT performance. While RMET and UOT appear similarly related in BAP/Non-BAP samples, use of emotion recognition abilities in a cognitive ToM task may reflect over-reliance on this skill in the BAP.
