Understanding the relationship between psychological factors of truck drivers is very important for accident prevention plans. This study investigates whether the negative work situation or work-family conflict positively affects sleep-related problems and whether sleep-related problems positively affect job dissatisfaction. The relationship was verified by structural equation modeling. The analysis was conducted with 184 truck drivers who drive daily from the 5th Korea Working Conditions Survey (KWCS) data. The structural equation modeling results found that work-family conflict (standardized path coefficient = 0.274) and negative work situation (standardized path coefficient = 0.203) had significantly affected sleep-related problems. Also, the sleep-related problems were more affected by the work-family conflict level than the negative work situation level. Sleep-related problems were found to correlate with job dissatisfaction (standardized path coefficient = 0.336). The relationship between negative work situation and work-family conflict on sleep-related problems and job dissatisfaction will help establish preventive policies for truck drivers’ safety and health.
