Evaluation of the Effect of Educational Intervention on the Cognitive Performance of Taxi Drivers Exposed to Heat Stress in a City in Southern Iran

Objectives: One of the occupations that is exposed to a lot of heat stress is taxi drivers. Due to their working conditions, these people spend a lot of time standing next to their cars in the sun to pick up passengers, and they are also exposed to heat stress throughout the entire driving journey. Therefore, the present study aimed to evaluate the effectiveness of an educational intervention program on the cognitive performance of taxi drivers exposed to heat stress in a city in southern Iran. Methods: The present study was a semi-experimental intervention that was conducted in three stages: initial assessment, training, and secondary assessment for 80 taxi drivers in two intervention and control groups. In the first stage, a general assessment of all drivers' knowledge and awareness of heat stress was performed, while cognitive parameters, including concentration skills and mental fatigue, were measured using a questionnaire. Then, training was given to the intervention group in both in-person and online formats. Two months after the start of training, cognitive parameters were measured for both intervention and control groups. Data analysis was also performed using SPSS software. Results: The results after the intervention showed that the training significantly increased concentration skills and significantly reduced mental fatigue (P<0.001). Regarding concentration skills and mental fatigue, along with all subcategories of the two questionnaires, the results showed that there was no significant difference between these variables before the intervention between the two groups. However, the difference between the two groups was significant after the intervention (P<0.001). Conclusion: Implementing an appropriate training program with follow-up over a period of two months to familiarize individuals with heat stress improved cognitive performance, and using follow-up training with a virtual structure improved the teaching and learning process and had an impact on individuals' performance.
