Background We examined the impact of ICT demands on the performance and psychological well-being at work (PWBW) of civil servants. The moderating role of employee position levels was also assessed. Therefore, we hypothesised that the impact of ICT would predict the performance (H1) and PWBW (H2) of civil servants and that employee position levels would play a moderating role in the relationship between the impact of ICT on civil servants' performance and PWBW (H3).Methods A total of 367 civil servants from different public institutions (35.01% female; Mage = 37.44 years, SDage = 7.35) responded to the questionnaire at all stages. The Work Performance scale, the PWBW scale and the ICT Demands scale were applied to assess the impact of ICT on participants’ work performance and PWBW respectively. Data were analysed using repeated measures analysis of variance, hierarchical linear regression and structural equation modeling (SEM).Results The results showed that the impact of ICT was generally more positive among supervisors than among the officers in T2 (1 year later) predicting a higher level of performance and PWBW of supervisors than officers in T3 (2 years later). The results also showed that employee position levels moderated the relationship between ICT demands, performance, and PWBW.Conclusions The results of this study provide important insights into the existing literature and help practitioners in the world of work, particularly in developing countries, to better understand how the introduction of a technological tool into employee practices can engender individual attitudes, emotions and behaviours that are appropriate or inappropriate for the goals of the organisation and how the employee's perception of a technological artifact changes according to job level.
