Abstract
Among the factors causing workers' anxiety, job-related factors are important since they can be managed. Therefore, this study aimed to analyze the association between work-related anxiety and job-related factors among Korean wageworkers using data from the Fifth Korean Working Conditions Survey. Participants were 13,600 Korean wageworkers aged <65 years. We analyzed the association between job-related factors and work-related anxiety, and the moderating effect of decision-making authority. "Meeting precise quality standards," "Solving unforeseen problems on your own," "Complex tasks," "Learning new things," "Working at very high speed," and "Working to tight deadlines" were positively associated with work-related anxiety. "Monotonous tasks" was negatively associated with work-related anxiety. The odds ratio (OR) of "Complex tasks" was higher in the group that had insufficient decision-making authority (OR 3.92, 95% confidential interval (CI) 2.40-6.42) compared to that with sufficient decision-making authority (OR 2.74, 95% CI 1.61-4.67). The risk of work-related anxiety was higher when the workers experienced time pressure, carried out tasks with high mental and physical demands, and dealt with unpredictable situations. This association was more pronounced when decision-making authority was insufficient.
