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 200 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 14.5 (sensitivity = 91.2, specificity = 77.8, and area under the curve = 0.89). Similarly, the best cut-off point value for the WPC was identified as 8.5, with a sensitivity of 93.9, specificity of 71.8, and area under the curve of 0.88. The evaluation results showed that 25 % of the workstations and 32 % 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.
