Abstract:

Background: This study aimed to evaluate the ergonomics of the office workplace and determine the cut-off point of the workstation layout checklist (WSLC) and the work posture checklist (WPC) of computer users. Methods: The descriptive-analytical was performed among ۲۰۰ office staff willing to cooperate at the university. To collect data and evaluate workstations and the posture of employees, the WSLC and WPC were used, respectively. The ROC curve was used to determine the cut point of the final score of the checklists. Results: The optimal cut-off point value for the WSLC was ۱۴.۵ (sensitivity = ۹۱.۲, specificity = ۷۷.۸, and area under the curve = ۰.۸۹). Similarly, the best cut-off point value for the WPC was identified as ۸.۵, with a sensitivity of ۹۳.۹, specificity of ۷۱.۸, and area under the curve of ۰.۸۸. The evaluation results showed that ۲۵ % of the workstations and ۳۲ % of the working postures of the employees were at an undesirable level. Conclusion: Determining the cut-off point for valid WSLC and WPC plays a crucial role in evaluating the cost, facilitation, speed, and repetition associated with office workplaces, thereby categorizing them as either desirable or undesirable. A quarter of the workstations and a third of the working postures of the employees were evaluated as undesirable.
