Introduction: Web sites are becoming the key for organizational survival in the global competition. Meanwhile university websites are considered as a necessary position for reflection of research activities and they must have a structure to respond to needs of users. Otherwise, users can be suffered of mental pressure due to the design and complexity of the system. The purpose of this study was to evaluate relationship between Research Centers system usability of Shiraz University of Medical Sciences and users' mental workload in three tasks of sending, reviewing and supervision of research projects.
Methods: In this descriptive-analytic cross-sectional study, 35 faculty members of Shiraz University of Medical Sciences participated. The data were collected by three questionnaires: NASA-TLX, System Usability Scale and Nilsson for evaluating mental workload and usability. Data analysis was done through 21spss.
Results: 60% of participants were women. The SUS for all three tasks was lower and equal to 50. The average total score of NASA-TLX was 49.8 and based on it, the highest and lowest scores were related to the performance and physical effort. The relationship between the NASA TLX index and the final score of SUS was significant (p <0.001). Using Nilsson's questionnaire, it was found that it is necessary to modify the flexibility dimension and efficiency in the system redesign.
Conclusion: The results showed that by increasing the usability of the system, the workload will be reduced. It is suggested that consideration be given to usability in the design of software systems as an important feature in improving human-computer interaction.
