This study explored whether children s movement and location during play measured via automated video tracking correlates with clinical features. Movement tracking metrics of 164 autistic children (27-96 months old) during free play were analyzed in relation to standard assessments of cognitive, language, social-communication, and adaptive skills. Children with higher cognitive and language abilities were more likely to spend time in the center toy region and more slowly or never approached the region without toys. Children with higher autism-related features spent less time in the center. Children with lower daily living skills spent more time near the caregiver and those with lower overall adaptive and language skills approached the caregiver more quickly. Over 90% of autistic children representing a range of ages and skills provided analyzable movement data during play and those with higher cognitive, language, and adaptive skills displayed movement tracking patterns that reflect more sustained focus on toy play and independence from the caregiver. Results suggest that automated movement tracking is a promising complementary, objective method for assessing clinical variation during autistic children s play.Lay AbstractPlay-based observations allow researchers to observe autistic children across a wide range of ages and skills. We recorded autistic children playing with toys in the center of a room and at a corner table while a caregiver remained seated off to the side and used video tracking technology to track children s movement and location. We examined how time children spent in room regions and whether or not they approached each region during play related to their cognitive, social, communication, and adaptive skills to determine if tracking child movement and location can meaningfully demonstrate clinical variation among autistic children representing a range of ages and skills. One significant finding was that autistic children who spent more time in the toy-containing center of the room had higher cognitive and language abilities, whereas those who spent less time in the center had higher levels of autism-related behaviors. In contrast, children who spent more time in the caregiver region had lower daily living skills and those who were quicker to approach the caregiver had lower adaptive behavior and language skills. These findings support the use of movement tracking as a complementary method of measuring clinical differences among autistic children. Furthermore, over 90% of autistic children representing a range of ages and skills in this study provided analyzable play observation data, demonstrating that this method allows autistic children of all levels of support needs to participate in research and demonstrate their social, communication, and attention skills without wearing any devices.

Automated Video Tracking of Autistic Children?s Movement During Caregiver-Child Interaction: An Exploratory Study / Alexandra L. BEY in Journal of Autism and Developmental Disorders, 54-10 (October 2024)

In this exploratory study, we examined the feasibility of using automated video tracking, Noldus EthoVision XT, to measure 159 2-to-7-year-old autistic children s patterns of movement during play-based, caregiver-child interactions and examined their associations with standard clinical measures and human observational coding of caregiver-child joint engagement. Results revealed that autistic children who exhibited higher durations and velocity of movement were, on average, younger, had lower cognitive abilities, greater autism-related features, spent less time attending to the caregiver, and showed lower levels of joint engagement. After adjusting for age and nonverbal cognitive abilities, we found that children who remained in close proximity to their caregiver were more likely to engage in joint engagement that required support from the caregiver. These findings suggest that video tracking offers promise as a scalable, quantitative, and relevant measure of autism-related behaviors.

Comparing ability and norm-referenced scores as clinical trial outcomes for neurodevelopmental disabilities: a simulation study / Cristan FARMER in Journal of Neurodevelopmental Disorders, 15 (2023)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 15 (2023) Titre : Comparing ability and norm-referenced scores as clinical trial outcomes for neurodevelopmental disabilities: a simulation study Type de document : texte imprimé Auteurs : Cristan FARMER, Auteur ; Audrey THURM, Auteur ; Jesse D. TROY, Auteur ; Aaron J. KAAT, Auteur Langues : Anglais (eng) Mots-clés : Humans  Communication  Learning  Neurodevelopmental Disorders/diagnosis  Patient Simulation  Ability score  Clinical outcome assessment  Clinical trials  Endpoints  Floor effect  Growth scale value  Item response theory  Neurodevelopmental disability  Rare genetic condition  Rasch analysis Index. décimale : PER Périodiques Résumé : BACKGROUND: For genetic conditions associated with neurodevelopmental disorder (GCAND), developmental domains such as motor ability, thinking and learning, social abilities, and communication are potential intervention targets. Performance on measures of developmental concepts can be expressed using several types of scores. Norm-referenced scores are intended for the diagnostic context, allowing for the identification of impairment relative to age-based expectations, and can exhibit dramatic floor effects when used in individuals with more significant limitations. Person ability scores, which are derived via Rasch analysis or item response theory, are available on many standardized tests and are intended to measure within-person change. However, they have not been used or evaluated as primary endpoints in GCAND clinical trials. In this study, we simulated a series of parallel-arm clinical trials under several chronological age and impairment conditions, to compare empirically the power and type I error rate of operationalizing test performance using ability scores rather than norm-referenced scores. RESULTS: Using the Vineland Adaptive Behavior Scales as the example, we demonstrated an advantage in statistical power of ability scores over norm-referenced scores at extreme levels of impairment. This advantage was at least partially driven by floor effects in norm-referenced scores. For simulated conditions where impairment was less severe, ability scores outperformed norm-referenced scores, but they were more similar. The type I error rate closely approximated the nominal type I error rate of 5% for both scores. CONCLUSION: The results of this simulation demonstrate a substantial power and interpretative advantage of ability scores over norm-referenced scores for studies of GCAND that will enroll participants with high levels of impairment. These results are expected to generalize to studies of developmental concepts, regardless of the etiology or specific test. However, the relative advantage of ability scores is expected to be even greater for tests with a higher floor than the Vineland.
