Public ISBD [article]  inAutism > 23-4 (May 2019) . - p.971-979 Titre : Autism at a glance: A pilot study optimizing thin-slice observations Type de document : Texte imprimé et/ou numérique Auteurs : L. H. HAMPTON, Auteur ; P. R. CURTIS, Auteur ; M. Y. ROBERTS, Auteur Article en page(s) : p.971-979 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  screening  thin-slice Index. décimale : PER Périodiques Résumé : Borrowing from a clinical psychology observational methodology, thin-slice observations were used to assess autism characteristics in toddlers. Thin-slices are short observations taken from a longer behavior stream which are assigned ratings by multiple raters using a 5-point scale. The raters' observations are averaged together to assign a "thin-slice" value for each observation. In this study, a total of 60 toddlers were selected from a video archive: 20 children with typical development, 20 children with developmental language disorder, and 20 children with autism. In the first part of this study, 20 raters observed small play segments between toddlers and an assessor. Raters assigned scores to each of the 60 toddlers on items related to autism symptomatology. Item analysis and generalizability and decision studies were conducted to determine the factor structure and optimal number of raters to achieve a stable estimate of autism characteristics. In the second part of the study, generalizability and decision studies were conducted to determine the most efficient and optimal combination of raters and naturalistic contexts. This pilot study provides recommendations for optimizing the utility of thin-slice observations for measuring autism symptomatology in young children.

Beyond pass-fail: Examining the potential utility of two thresholds in the autism screening process / M. Y. ROBERTS in Autism Research, 12-1 (January 2019)  

Public ISBD [article]  inAutism Research > 12-1 (January 2019) . - p.112-122 Titre : Beyond pass-fail: Examining the potential utility of two thresholds in the autism screening process Type de document : Texte imprimé et/ou numérique Auteurs : M. Y. ROBERTS, Auteur ; Y. STERN, Auteur ; L. H. HAMPTON, Auteur ; J. M. GRAUZER, Auteur ; A. MILLER, Auteur ; A. LEVIN, Auteur ; B. KORNFELD, Auteur ; M. M. DAVIS, Auteur ; A. KAAT, Auteur ; R. ESTABROOK, Auteur Article en page(s) : p.112-122 Langues : Anglais (eng) Mots-clés : Children  autism  early detection  early signs Index. décimale : PER Périodiques Résumé : Access to early intervention as early in development as possible is critical to maximizing long-term outcomes for children with autism spectrum disorders (ASD). However, despite the fact that ASD can be reliably diagnosed by 24 months, the average age of diagnosis is 2 years later. Waitlists for specialized developmental evaluations are one barrier to early diagnosis. The purpose of this study was to examine one potential approach to reducing wait time for an ASD diagnostic evaluation by examining the utility of using more than one threshold for an autism screening tool, the Screening Tool for Autism in Toddlers and Young Children (STAT). Participants included 171 children between 24 and 36 months of age who received a medical diagnostic evaluation through Illinois' Early Intervention Program. This study directly compared the performance of the STAT when scored: (a) using the original single threshold, (b) using seven equally weighted items using a single threshold, and (c) using all items differentially weighted based on how strongly that item predicts a later ASD diagnosis. In addition, this study explored the potential utility of using two thresholds rather than a single threshold for each scoring method. Results of this study suggest that using a two-threshold logistic regression method has potential psychometric advantages over a single threshold and categorical scoring. Using this approach may reduce the wait time for specialty ASD diagnostic evaluations by maximizing true negatives and true positives, such that specialty evaluations may be reserved for those cases that are more ambiguous or more complex. Autism Research 2019, 12: 112-122. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This study examined the benefits of using two versus one cutoff score when screening for autism. Results indicate that having two scores and weighting test items based on predictive association with an autism diagnosis is better than using a single score and weighting each item equally. Using such an approach may reduce the wait time for specialty autism diagnostic evaluations, such that specialty evaluations may be reserved for those cases that are more ambiguous or more complex.

Measuring parent strategy use in early intervention: Reliability and validity of the Naturalistic Developmental Behavioral Intervention Fidelity Rating Scale across strategy types / B. J. SONE in Autism, 25-7 (October 2021)

For these treatments to be effective, it is important for the parent to implement the strategies as intended. However, measurement of parent strategy use is inconsistent across studies of parent-implemented interventions. This study evaluates the quality of the NDBI-Fi, an efficient measure, compared to a more time-consuming measure that is known to be precise. Videos of parents playing with their children were used to compare these two measurement methods. Results demonstrated that the NDBI-Fi was of good quality: scorers had high levels of agreement, the NDBI-Fi was similar to the more precise measure in rating parents after intervention, it detected changes from before to after intervention, and it detected differences when parents learned different types of intervention strategies. The NDBI-Fi was not as precise as the other measure across all strategies before parents learned intervention. Taken together, the findings of this study support the use of the NDBI-Fi as a high-quality outcome measure.
