The survey of relationship between occupational cognitive failures and safety performance among bus drivers

Accidents and injuries are a cause for concern for all countries in the world. Cognitive failures can be defined as cognitive-based errors on simple tasks that a person should normally be able to complete without fault; these mistakes include problems with memory, attention or action. The present study was designed to investigation of relationships between occupational cognitive failures and safety performance among bus drivers.

In this descriptive analytical study, 129 bus drivers completed an occupational cognitive failure questionnaire (OCFQ) and the DBQ as well as answered questions on accident involvements. Correlation and regression analysis were used for data processing.

Occupational cognitive failures have a significant direct positive effect on all driving unsafe behaviors including intended and unintended violations, slips and mistakes.

For assessment of safety performance in occupational driving jobs, we must use a valid instrument. The cognitive failures can predict bus drivers’ engagement in safe or unsafe behaviors.
