Validation of Rating Scale Mental Effort for Assessing Mental Workload in Nurses

Workload can be defined as the operator's required capacity to meet a special level of performance while performing a task. The workload threatens the health of people as well as influences the quality and quantity of service. We aimed to evaluate the validation of Rating Scale Mental Effort (RMSE) to assess nurse's mental workload.
This cross-sectional study was conducted on75 nurses. The data was collected by NASA-TLX index and Rating Scale Mental Effort, and analyzed in SPSS 20, using descriptive statistics, Independent samples t-test, ANOVA and Pearson correlation coefficient test.
Findings: The results showed that nurse's workload was high. There was a notable correlation between RMSE and The NASA Task Load Index (r=0.72).
The results of this study showed that RMSE is an appropriate method for assessing mental workload among nurses.
