As a result of the COVID-19 pandemic, people began to use the Internet more actively. Accordingly, the question arises of how the accelerated digitalization, which became one of the results of the pandemic, has affected various aspects of our lives, including our attitude to the political power institutions. This article discusses the relation of Internet usage activity and the trust toward the political institutions in European countries. There are contradicting data in the literature regarding the relationship between institutional trust and the activity of using the Internet. We assumed that the direction of relationship is associated with the efficiency of the state power institutions. Based on the government effectiveness index, we have chosen five European countries with the highest government efficiency and five countries with the lowest. To assess the activity of using the Internet, we used data from the European Social Survey (ESS) that show the average frequency of Internet use during the month and the average duration of its use during the day. The dependent variables were respondents' assessments of their own trust in the different political institutions. Next, using multiple regression analysis, we assessed the relationship between two indicators of Internet use activity and trust in each of the institutions. The results of the regression analysis demonstrated that in the countries with low government efficiency, the activity of Internet usage is negatively associated with trust in various political institutions. In countries with high government efficiency, we found a positive relationship between Internet usage activity and institutional trust.
