Abstract Text:Background: Advances in the development of e-health applications enhance the availability ofpreventive tools and the adherence to certain treatments in old age (Roberts et al., 2015; Granath et al.,2023). Using these apps provides benefits for cognitive stimulation, offering a technologically accessibleoption that promotes autonomy in the elderly. In this study, we present the app version of a web platformfor cognitive stimulation in the elderly called LABPSI (https://labpsi.mdp.edu.ar). This lite version can bedownloaded for android mobile phones and used offline. The app was developed based on user-centered design, focusing on the elderly. The aim of this study is to assess the usability of the appversion of LABPSI in this population.Methods: The sample consisted of 16 elderly people (81 % women) with a mean age of 71.5 (DS=8.72)and an average of 10.9 years of education.Initially, users were introduced to the app providing the necessary time for use and exploration.Subsequently, they answered the MAUQ (Zhou L. et al., 2019) e-health application usabilityquestionnaire to assess participants' perceived ease of use, satisfaction, and utility when using LABPSI.The LABPSI final prototype was developed using App Inventor software (MIT APP INVENTOR, 2012).Results:The descriptive analysis of the MAUQ usability questionnaire variables were: a) ease of use; b)interface and satisfaction; c) utility. The first variable had a median value of 22 with a maximumquestionnaire score of 25 and a range of responses of [6-25]. The second variable had a median value of 30, with a maximum questionnaire score of 35, and a range of responses of [21, 35]. Finally, the utilityvariable scored a median of 26 with respect to the maximum questionnaire score of 30, with a range of[16-30].Conclusions: This usability study on the new LABPSI cognitive stimulation app shows high levels ofease of use, satisfaction, and perceived utility by participants. The results demonstrate a goodinteraction between the elderly and the system, defining the app as a usable, appealing, and easy tolearn software product for end-users
