Objectives: The purpose of this study was to evaluate the validity of action naming tests when using a chatbot-based online platform. The performance of healthy young adults and healthy middle-aged adults on action naming tests was compared between online assessment platforms.Methods: A total of 81 participants were included in this study (40 young adults, 41 middle-aged adults). Participants were divided into two groups according to the online assessment platforms, 40 individuals (20 young adults, 20 middle-aged adults) receiving the action naming tests via Zoom and 41 individuals (20 young adults, 21 middle-aged adults) via chatbot.Results: The results indicated that there was no significant difference in action naming performance across online assessment platforms. In addition, young adults showed statistically higher performance compared to the middle-aged adults. There was a significant main effect of verb argument structure on action naming performance, with one- and two-place verbs having a higher correct response rate than three-place verbs.Conclusion: Although the younger group performed better than the middle-aged group, there were no significant differences in action naming performance between chatbot and Zoom groups, suggesting that chatbot-based action naming tests can be used interchangeably with the established online platforms. Accordingly, it is expected that we will be able to provide appropriate online language assessment services for each client in a future clinical setting.
