Abstract

Background and Objective: Nowadays, the saliency of workload has become more apparent in ergonomic studies. Workload can cause incident since it is directly related to unsafe situations at work. Therefore, it is important to measure workload in different occupations. This study was conducted to evaluate the Validity and Reliability of Driver Activity Load Index Questionnaire for assessing the mental load of Drivers. Materials and Methods: This cross-sectional and descriptive-analytic study was conducted on 100 bus Drivers operating in one of the manufacturing companies. The validity of the questionnaire was evaluated by academic and queue experts (lay experts). Additionally the reliability of this index was measured through employing Cronbach's alpha and intra-cluster correlation test on the data obtained from 10 participants. Data were analyzed using SPSS (version 18) software. Results: The mean age of participants was 50. 8 years with the standard deviation of 8. 29. Furthermore, the mean of work experience among Drivers was 22. 18 years. The outcome of the Cronbach’ s alpha coefficient revealed that the reliability of the questionnaire was higher than 0. 7. Furthermore, intra-cluster correlation coefficient of the questionnaire was estimated higher than 0. 7 in all factors affecting the interference factor. The obtained results were indicative of moderate and optimum level of reliability. Conclusion: According to the results of Validity and Reliability indices, the Driver Activity Load Index Questionnaire can be used as a valid and reliable questionnaire in Iran to examine and measure the mental load of Drivers.
