The Verification of Causality among Accident, Depression, and Cognitive Failure of the Train Drivers

Abstract

This study intended to testify the causality among three variables such as accident, depression and cognitive failure of the train drivers. For this purpose, two research models were suggested. Model 1 hypothesized the causality among three variables as 'depression ⟶ cognitive failure ⟶ accident'. On the other hand, model 2 hypothesized the causality among three variables as 'accident ⟶ depression ⟶ cognitive failure'.Results based on AMOS using 416 train drivers' questionnaire showed that model 2 is more valid than model 1. The statistical result of model 1 showed that depression has a positive effect on cognitive failure, however no significant relationship between depression and accident as well as between cognitive failure and accident. In model 2, the result showed that the accident has a positive effect on cognitive failure mediated by depression. This result suggests the necessity for establishment of countermeasures to mitigate mistake and cognitive failure caused by train drivers in a wider context, considering the causality between accident and depression.

Assessing cardiovascular links to depression and anxiety in Australian professional drivers

“…Train and truck drivers experience a myriad of unique occupational workplace factors, such as monotonous driving conditions, long hours spent sitting, the necessity of strict mental alertness, workplace social isolation and the potential for "person under vehicle" events. These conditions have been postulated to contribute to a high incidence of health conditions such as depression [3][4][5][6][7][8][9], anxiety [10][11][12][13] and cardiovascular disease (CVD) [14][15][16] amongst this population.…”
