Abstract

This study aimed to investigate how work-life balance (WLB) corresponds to cognitive functions and which mental health conditions play a mediating role in this association among Korean bus drivers. The cognitive failures questionnaire (CFQ) was administered to 347 bus drivers in Seoul, Korea. The differences in the CFQ and WLB scores were examined by analysis of covariance, and a structural equation model (SEM) was constructed for investigating the mediating role of mental health indices between WLB and CFQ scores. Compared with the highest subjective work-life balance group, the lowest group had significantly higher CFQ scores. In the SEM, anxiety was a mediating variable between subjective work-life balance and CFQ scores. Work-life balance is associated with cognitive failures among Korean bus drivers, and anxiety was a key mediating mental health indicator.
