Background: This study aims to validate the content and evaluate the usability of the Autism App for screening children with autism spectrum disorder.
Methods: This methodological study was conducted between August 2023 and March 2024. The study included 15 experts for content validation and nine for usability evaluation, all of whom had experience in the health/technology field. Content validation data were analyzed using the Content Validity Ratio (CVR), and usability was assessed through heuristics using the MATcH-MED instrument.
Results: The content validation showed satisfactory CVR values, ensuring the validity of the developed application, with suggestions for revisions regarding aims and structure. The usability evaluation yielded an overall average score of 50.9 points, classified as a high level of usability.
Conclusion: The results demonstrated that the App-Autismo has adequate evidence of content validity and usability. By incorporating the experts' suggestions, this tool can be tested in future research for its effectiveness and efficiency.
