83 Efficacy of a Tablet-Based Cognitive Flexibility Intervention in Youth with Executive Function Deficits
Notice bibliographique
Résumé
Objective: Executive functions (EFs) are considered to be both unitary and diverse functions with common conceptualizations consisting of inhibitory control, working memory, and cognitive flexibility. Current research indicates that these abilities develop along different timelines and that working memory and inhibitory control may be foundational for cognitive flexibility, or the ability to shift attention between tasks or operations. Very few interventions target cognitive flexibility despite its importance for academic or occupational tasks, social skills, problem-solving, and goal-directed behavior in general, and the ability is commonly impaired in individuals with neurodevelopmental disorders (NDDs) such as autism spectrum disorder, attention deficit hyperactivity disorder, and learning disorders. The current study investigated a tablet-based cognitive flexibility intervention, Dino Island (DI), that combines a game-based, process-specific intervention with compensatory metacognitive strategies as delivered by classroom aides within a school setting. Participants and Methods: 20 children between ages 6-12 years (x̄ = 10.83 years) with NDDs and identified executive function deficits and their assigned classroom aides (i.e., “interventionists”) were randomly assigned to either DI or an educational game control condition. Interventionists completed a 2-4 hour online training course and a brief, remote Q&A session with the research team, which provided key information for delivering the intervention such as game-play and metacognitive/behavioral strategy instruction. Fidelity checks were conducted weekly. Interventionists were instructed to deliver 14-16 hours of intervention during the school day over 6-8 weeks, divided into 3-4 weekly sessions of 30-60 minutes each. Baseline and post-intervention assessments consisted of cognitive measures of cognitive flexibility (Minnesota Executive Function Scale), working memory (Weschler Intelligence Scales for Children, 4th Edn. Integrated Spatial Span) and parent-completed EF rating scales (Behavior Rating Inventory of Executive Function). Results: Samples sizes were smaller than expected due to COVID-19 related disruptions within schools, so nonparametric analyses were conducted to explore trends in the data. Results of the Mann-Whitney U test indicated that participants within the DI condition made greater gains in cognitive flexibility with a trend towards significance (p = 0.115. After dummy coding for positive change, results also indicated that gains in spatial working memory differed by condition (p = 0.127). Similarly, gains in task monitoring trended towards significant difference by condition. Conclusions: DI, a novel EF intervention, may be beneficial to cognitive flexibility, working memory, and monitoring skills within youth with EF deficits. Though there were many absences and upheavals within the participating schools related to COVID-19, it is promising to see differences in outcomes with such a small sample. This poster will expand upon the current results as well as future directions for the DI intervention.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
