Autism at a glance: A pilot study optimizing thin-slice observations / Lauren H. HAMPTON in Autism, 23-4 (May 2019)  

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 Auteurs : Lauren H. HAMPTON, Auteur ; P.R. CURTIS, Auteur ; Megan 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 / Megan 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 Auteurs : Megan Y. ROBERTS, Auteur ; Yael STERN, Auteur ; Lauren H. HAMPTON, Auteur ; Jeffrey M. GRAUZER, Auteur ; Amanda MILLER, Auteur ; Amy LEVIN, Auteur ; Benjamin KORNFELD, Auteur ; M.M. DAVIS, Auteur ; Aaron J. KAAT, Auteur ; Ryne 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.

Generalized Effects of Naturalistic Social Communication Intervention for Minimally Verbal Children with Autism / Lauren H. HAMPTON in Journal of Autism and Developmental Disorders, 51-1 (January 2021)

The current study examined the effects of this naturalistic intervention on social language use in three children with autism who were in the early stages of language acquisition. Generalization to communication partners who did not utilize the intervention strategies was systematically examined using a multiple-baseline design. The results from this study indicate that this blended intervention is effective in increasing target social language for young children with autism, however, generalization to communication partners does not readily occur. Implications for practice and future research are discussed.

Increasing dependability of caregiver implementation fidelity estimates in early intervention: A generalizability and decision study / Lauren H. HAMPTON in Autism, 30-1 (January 2026)  

Public ISBD [article]  inAutism > 30-1 (January 2026) . - p.187-196 Titre : Increasing dependability of caregiver implementation fidelity estimates in early intervention: A generalizability and decision study Type de document : texte imprimé Auteurs : Lauren H. HAMPTON, Auteur ; Micheal P. SANDBANK, Auteur ; Jerrica BUTLER, Auteur ; Annabel GARZA, Auteur Article en page(s) : p.187-196 Langues : Anglais (eng) Mots-clés : autism  caregiver-implemented interventions  generalizability  Naturalistic Developmental Behavioral Interventions Index. décimale : PER Périodiques Résumé : There is an increasing need to measure caregiver implementation of strategies from Naturalistic Developmental Behavioral Interventions (NDBIs) as a possible key mediator of outcomes in a child. The NDBI Fidelity (NDBI-Fi) rating scheme is a macro-code to estimate the implementation of core strategies. Yet, there is a need to understand the dependability of this measure to ensure intervention study findings are generalizable to everyday interactions and comparable across studies. We addressed this by evaluating the dependability or consistency of NDBI-Fi scores for 20 caregivers, averaged across observations of two occasions of two routines that were each scored by two raters. Our findings indicated that a single score (i.e. from a single occasion, single routine, and single rater) from the measure has low dependability (g = 0.43). When scores were averaged across two observations each of two routines scored by two raters (i.e. eight scores total), the score was more dependable (g = 0.77). The majority (81.6%) of absolute error variance was attributable to occasions of observation and its interaction with other facets (routine or rater). Therefore, we recommend the NDBI-Fi be applied to more than one observation of more than one routine to strengthen confidence that scores are generalizable to everyday parent-child interactions.Lay abstract Outcomes from caregiver-mediated interventions typically include measuring the caregiver’s use of key techniques. The Naturalistic Developmental Behavioral Intervention-Fidelity (NDBI-Fi) tool is a valid measurement strategy for estimating caregiver use. In this study, we sought to understand how to improve data collection from natural observations of caregivers with their children to ensure the scores are representative of how the caregiver and child typically interact. We observed 20 caregiver-child pairs via telehealth in snack and play routines over two different days. Each video was rated using the NDBI-Fi by two observers. We learned that increasing the number of observations may be the best way to improve the dependability of scores from natural caregiver-child observations. This study adds to recent research seeking to understand how to best measure caregiver strategy use. These findings may guide future researchers and clinicians to consider increasing the number of observations used to evaluate caregiver use of intervention techniques in research studies or clinical practice.
