One potential solution is to use machine learning to guide the prediction of the response to intervention. Thus, our study compared five machine algorithms in estimating treatment prognosis on two outcomes (i.e., adaptive functioning and autistic symptoms) in children with autism receiving early behavioral intervention in a community setting. Each machine learning algorithm produced better predictions than random sampling on both outcomes. Those results indicate that machine learning is a promising approach to estimating prognosis in children with autism, but studies comparing these predictions with those produced by qualified practitioners remain necessary.

Changes in Autistic Symptoms and Adaptive Functioning of Children Receiving Early Behavioral Intervention in a Community Setting: A Latent Growth Curve Analysis / Isabelle PREFONTAINE in Journal of Autism and Developmental Disorders, 53-3 (March 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-3 (March 2023) . - p.901-917 Titre : Changes in Autistic Symptoms and Adaptive Functioning of Children Receiving Early Behavioral Intervention in a Community Setting: A Latent Growth Curve Analysis Type de document : Texte imprimé et/ou numérique Auteurs : Isabelle PREFONTAINE, Auteur ; Julien MORIZOT, Auteur ; Marc J. LANOVAZ, Auteur ; Mélina RIVARD, Auteur Article en page(s) : p.901-917 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Despite showing effects in well-controlled studies, the extent to which early intensive behavioral intervention (EBI) produces positive changes in community-based settings remains uncertain. Thus, our study examined changes in autistic symptoms and adaptive functioning in 233 children with autism receiving EBI in a community setting. The results revealed nonlinear changes in adaptive functioning characterized by significant improvements during the intervention and a small linear decrease in autistic symptoms from baseline to follow-up. The intensity of intervention, initial age, IQ and autistic symptoms were associated either with progress during the intervention or maintenance during the follow-up. The next step to extend this line of research involves collecting detailed data about intervention strategies and implementation fidelity to produce concrete recommendations for practitioners.

Effects of multiple interventions for reducing vocal stereotypy: Developing a sequential intervention model / Marc J. LANOVAZ in Research in Autism Spectrum Disorders, 8-5 (May 2014)

Consequently, practitioners have limited amount of data to make informed decisions on whether an intervention may be more suitable than another to begin treating vocal stereotypy. The purpose of the study was to address this limitation by examining the direct and collateral effects of multiple interventions in 12 individuals with autism and other developmental disabilities in order to guide the development of a sequential intervention model. Using single-case experimental designs, we conducted a series of four experiments which showed that (a) noncontingent music generally produced more desirable outcomes than differential reinforcement of alternative behavior, (b) differential reinforcement of other behavior reduced vocal stereotypy in two participants for whom noncontingent music had failed to do so, (c) the addition of simple prompting procedures may enhance the effects of the interventions, and (d) the effects of noncontingent music may persist during sessions with extended durations. Based on these results, we propose a sequential intervention model to facilitate the initial and subsequent selection of an intervention most likely to reduce vocal stereotypy while producing desired collateral outcomes.

Effects of reducing stereotypy on other behaviors: A systematic review / Marc J. LANOVAZ in Research in Autism Spectrum Disorders, 7-10 (October 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-10 (October 2013) . - p.1234-1243 Titre : Effects of reducing stereotypy on other behaviors: A systematic review Type de document : Texte imprimé et/ou numérique Auteurs : Marc J. LANOVAZ, Auteur ; Kirsty M. ROBERTSON, Auteur ; Kara SOERONO, Auteur ; Nicholas WATKINS, Auteur Article en page(s) : p.1234-1243 Langues : Anglais (eng) Mots-clés : Autism  Collateral behavior  Developmental disabilities  Intervention  Literature review  Stereotypy Index. décimale : PER Périodiques Résumé : Researchers have shown that high levels of stereotypy in individuals diagnosed with autism spectrum disorders were correlated with more significant impairments in social and adaptive functioning. Reducing stereotypy may thus potentially occasion an increase in appropriate social and adaptive behaviors. Hence, the purpose of this systematic review was to examine the effects of reducing stereotypy on engagement in other behaviors. Following a thorough literature search, we identified 60 studies that both reduced engagement in stereotypy and measured engagement in at least one other behavior. We divided the studies into six broad categories: noncontingent reinforcement, differential reinforcement, punishment-based interventions, multiple contingencies, physical exercise, and other antecedent-based interventions. The results of our analyses suggest that reducing stereotypy produces reallocation toward other behaviors, albeit not necessarily appropriate. As such, clinicians and researchers targeting stereotypy should plan to strengthen an appropriate alternative behavior while targeting all response forms of stereotypy for reduction. Moreover, our review suggests that measuring untargeted behaviors when implementing interventions designed to reduce stereotypy may be essential in clinical and research settings.
