Objectives: This study aimed to assess a pilot program designed to improve the executive functions of a child five years and nine months in age with ASD. Methods: To evaluate the effects of the intervention, observational methodology was used, which is considered a mixed method in itself as it integrates both qualitative and quantitative elements in its various phases. Specifically, an idiographic, longitudinal, and multidimensional design was followed. A lag sequential analysis was conducted using GSEQ software Version 5.1, enabling us to study changes in the executive functions of a child before, during, and after the intervention, including whether its effects are sustained over time. Results: The sequential patterns obtained indicate more appropriate and complex executive functioning after the three-month intervention, specifically increased cognitive flexibility, improved self-regulation, more accurate evaluation, and progress in inhibitory processes. However, these improvements do not persist over time. Conclusion: This study contributes to the scarcely explored field of executive function interventions in children with ASD, although it is necessary to consider the generalization of the results to other contexts, such as family and school, during interaction with peers. info:eu-repo/grantAgreement/ES/DGA/S49-23R info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.1 2024 PEDIATRICS 61 / 191 = 0.319 2024 Q2 T1 0.674 2024 Pediatrics, Perinatology and Child Health 2024 Q2 3.8 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Escolano-Pérez, Elena Universidad de Zaragoza (orcid)0000-0001-8471-9415 4009 735 Universidad de Zaragoza Dpto.
