Results: The proportion of participants with a high K10 score was 15% (n ¼ 106). Having little conversation
with their supervisor and/or coworkers significantly increased the risk of depression [odds ratio
(OR) 1.8], as did high job overload (OR 2.7) and job dissatisfaction (OR 3.8), compared with employees
who frequently conversed with their supervisor and/or coworkers. Caring for elderly relatives as a
prominent characteristic of an employee was a significant risk factor for depression (OR 2.1).
Conclusion: The present study demonstrated that employees who were caring for elderly relatives were
significantly associated with an increased risk of depression. To prevent depressive disorders, it may be
important to focus on reducing the work-caregiving role conflict, as well as enhancing employees’ job
control and better rewarding their efforts in the workplace.
