In this study, we examine the determinants of the adoption of electronic services of the Moroccan Ministry of the Interior using the Unified Theory of Acceptance and Use of Technology (UTAUT) as a theoretical framework. The main objective is to identify the factors influencing the intention to use and the effective adoption of e-government services by Moroccan citizens, with a focus on expected performance, expected effort, facilitating conditions, and social influence. To this end, a quantitative survey was conducted with a sample of 246 Moroccan citizens, and the data collected were analyzed using factor analysis and multiple regression. The results show that expected performance, facilitating conditions, and social influence are determining factors for the intention to use and adoption of e-government services by Moroccan citizens. This research has significant implications for policymakers and practitioners in the field of e-government. The findings of the study suggest that to promote the adoption of online services of the Ministry of the Interior, it is crucial to take into account these key factors and implement measures aimed at improving expected performance, facilitating conditions, and social influence.
