Background and Objectives: In today's IT-based workplaces, effective use of IT systems is crucial for enhancing user performance (Badda & Rahmouni, 2023). However, the inherent complexity of these systems can significantly affect how users interact with technology and, ultimately, their productivity (Verna et al., 2023). Perceived complexity refers to users' perceptions of the difficulty associated with understanding and using technology (Te'eni, 1989). Perceived IT complexity commonly occurs in organizational contexts characterized by distributed work environments, complex network structures, software projects involving multiple roles and interactions, high dependencies between subsystems, a diversity and multiplicity of applications, and changing and complex business needs (Storm & Scheepers, 2019). According to Stoica et al. (2024), organizations with networked structures, numerous applications, and high dependencies among IT components experience higher levels of perceived complexity. Accordingly, working across different locations and within distributed teams may further increase users' perceptions of IT complexity. Despite considerable attention to IT complexity and its potential consequences in previous research, the mechanisms through which perceived IT complexity translates into actual user performance have not yet been fully understood (Badda & Rahmouni, 2023). One potentially important mechanism is the frequency of information system use. While previous studies have examined system quality, service quality, user satisfaction, and performance, the mediating role of frequency of use in the relationship between perceived information system complexity and user performance requires further investigation. The existing evidence also suggests a complex relationship between these variables. On the one hand, perceived system complexity may discourage repeated use and consequently limit the development of users' skills and effective performance. On the other hand, frequent system use may increase users' familiarity with technology and thereby reduce some of the negative consequences associated with perceived complexity. Thus, frequency of use may serve as an important mechanism linking perceived complexity to user performance. Understanding this relationship is particularly important in educational organizations that rely on multiple information systems. Shahid Chamran University of Ahvaz, as one of the major universities in Iran, employs numerous information systems to support educational, research, student, cultural, financial, administrative, and knowledge-related activities. This multiplicity of systems may increase users' perceived complexity and influence their performance. Therefore, the present study aimed to investigate the effect of perceived IT complexity on the performance of users at Shahid Chamran University of Ahvaz, with particular emphasis on the mediating role of frequency of information system use.
Methodology: This study was applied in terms of purpose and employed a survey method with a causal-correlational approach to examine the relationships among the independent, dependent, and mediating variables. The statistical population consisted of 1,503 users of information systems at Shahid Chamran University of Ahvaz. Based on the criterion of 15 respondents per questionnaire item, the required sample size was estimated at 420 participants. Participants were selected using convenience sampling. Of the distributed questionnaires, 286 completed questionnaires were considered valid and included in the final analysis. The collected data were analyzed using SmartPLS software to examine the direct and indirect relationships among perceived IT complexity, frequency of information system use, and user performance.
Findings: The results showed that the mean score of perceived IT complexity was 3.33, indicating that users perceived the university's information technologies and information systems as moderately complex. This level of perceived complexity suggests that difficulties associated with understanding and using the systems may interfere with their effective utilization.
The hypothesis-testing results showed that perceived IT complexity had a negative effect on the performance of users at Shahid Chamran University of Ahvaz. A negative and significant relationship was observed between perceived complexity and user performance (reported coefficient = -0.221). Thus, higher levels of perceived complexity were associated with lower levels of user performance.
The results also showed that perceived IT complexity had a significant negative effect on the frequency of users' use of university information systems (β = -0.533). In other words, as users perceived information systems to be more complex, the frequency with which they used those systems decreased. This finding suggests that complexity may discourage continued interaction with information systems and consequently limit opportunities for users to develop familiarity and proficiency.
Furthermore, the analysis of the mediating relationship showed that perceived IT complexity had a significant negative indirect effect on user performance through frequency of information system use. The reported t-value for the indirect effect was 7.34, exceeding the critical value of 1.96 and indicating statistical significance at the 0.05 level. These findings demonstrate that frequency of use plays a significant mediating role in the relationship between perceived IT complexity and user performance. Accordingly, perceived complexity not only affects performance directly but may also reduce performance indirectly by decreasing users' frequency of interaction with information systems.
Discussion: The findings indicate that perceived IT complexity is an important factor affecting both the frequency of information system use and user performance. As users perceive organizational information systems to be more complex, they tend to use them less frequently, which in turn may negatively affect their performance. The significant mediating role of frequency of use highlights the importance of continuous interaction with information systems in reducing some of the adverse consequences associated with perceived complexity.
Therefore, improving the usability and simplicity of university information systems, reducing unnecessary complexity, enhancing integration among different systems, and providing appropriate user training may encourage more frequent system use and contribute to improved user performance. These findings can assist university managers and information system designers in developing more user-centered systems and improving the effective use of information technology in academic environments
