This study examines the factors that stimulate developing country citizens' E-government adoption behaviour. The UTAUT model was adopted along with technology anxiety (TA) as an extended construct. Based on the quantitative research method, a total of 297 survey data was collected to perform data analysis through Structural equation modelling (SEM). This study reveals that variables like- 'Performance Expectancy' (PE), 'Effort Expectancy' (EE), 'Social Influence' (SI) and 'Facilitating Conditions' (FC) were positively related to 'Behavioural Intention' (BI) to use E-Government Services (E-govS). Additionally, technology anxiety (TA) was a negative predictor of BI. In implication, this study enriches the understanding of influencing factors behind the uses of E-GovS in Bangladesh. Additionally, the stimulus factors identified in this study will benefit the government and other relevant policymakers of developing countries, particularly Bangladesh, to increase and modify the rate of acceptance and adoption of E-GovS.
