While it is important to understand citizens' trust in e-government, theory on this topic does not accommodate potential differences between innovators and non-innovators. To investigate factors of trust development for two groups (innovators and non-innovators) and produce a multigroup model we conducted an EFA and CFA, followed by Structural Equation Modelling to test hypotheses for each group. We used the Perceived Innovativeness in IT (PIIT) construct to identify innovators and non-innovators. Our findings demonstrate that e-government trust processes for innovators and non-innovators are different, and our model accounts for more than half the variance in Trust in e-Government. Key antecedents for innovators are Technology Self-Efficacy and Trust in Government, and for non-innovators are Technology Self-Efficacy and Social Influence. We discuss some of the implications of these findings for both theory and practice.
