Today, one of the major problems that governments face is the reduced level of trust of people in governments which is referred to as the crisis of public trust. One way for governments to overcome such crisis is becoming electronic. The overall objective of this research is studying the impact of each of e-government indexes on public trust. A questionnaire containing 28 questions and in 2 parts was prepared and for statistical procedures, first Kolmogorov-Smirnov test (KS-test) was used to determine the normality of indexes and then for testing the presence or absence of correlation, two correlation tests were used to determine the impacts of the relations and their status. The results of the research indicate that four aforementioned hypotheses are confirmed at error level of 5%.
