Abstract
Background: Workers spend most of their social lives at work and have relationships of varying nature with people in the workplace. Direct supervisors, in particular, have a direct and lasting impact on workers, which may influence workers¡¯ mental health. Depression is very prevalent worldwide, and social concern about the disease is on the rise. The aim of this study is to investigate the effect of direct supervisors¡¯ behavior on the depressive mood of Korean wage workers.

Methods: We used data from the 4th Korean Working Conditions Survey held in 2014; 22,212 participants were included in the analysis. The quality of a direct supervisor¡¯s behavior was categorized from 0 (= lowest) to 5 (= highest) points. The degree of depressive mood was measured on a scale from ¡°normal mood¡± to ¡°likely depression¡± based on the 5-item World Health Organization Well-Being Index (WHO-5) questionnaire. Multiple logistic regression was used to analyze the association between the quality of the direct supervisor¡¯s behavior and the depressive mood of wage workers.

Results: After multivariable adjustment, significantly increased odds ratio (OR) for likely depression was found in the 4, 3, 2, 1, and 0 points of the quality of the direct supervisor¡¯s behavior compared to 5 points. After stratification for the level of satisfaction with working conditions, the OR of the unsatisfied groups was higher than that of the satisfied groups.

Conclusions: Likely depression was found to be significantly associated with a low quality of direct supervisor¡¯s behavior. This association was stronger in workers who were not satisfied with their working conditions. This study suggests that proper management of the direct supervisor¡¯s behavior is needed to reduce the risk of depression among Korean wage workers.
