This study investigates the factors influencing the acceptance and use of the WIQAYTNA contact tracing application in Morocco using an extended Unified Theory of Acceptance and Use of Technology (UTAUT) model. The model incorporates perceived security risk (PR) and perceived compatibility (PC) alongside core UTAUT constructs: Performance Expectancy (PE), Effort Expectancy (PU), and Social Influence (SI). The findings indicate that performance expectancy, social influence, effort expectancy, and perceived compatibility have a significant positive influence on behavioral intention BI to adopt the application. However, perceived security risk negatively impacts adoption, suggesting privacy concerns and data protection issues are substantial barriers to user acceptance. The study emphasizes the need for user-friendly design, alignment with user values, robust data protection policies, and transparent communication strategies to foster trust and encourage widespread engagement with digital contact tracing applications.
