Customer verbal abuse is associated with depressive symptoms among high-workload cosmetics sales workers in South Korea

This study sought to investigate whether association between customer verbal abuse and depressive symptoms differed by workload. We conducted a cross-sectional survey of 795 cosmetics sales workers at department store in South Korea. Experience of customer verbal abuse over the past one month was measured by using a yes/no question. Depressive symptoms during the preceding week were assessed by using 20 items from the Center for Epidemiologic Studies-Depression scale. Workload during the past week was measured by asking the number of customers a worker dealt with on average in a day and classified into two categories: 1) Low (15 people or less), and 2) High (more than 15 people). Cosmetics sales workers' experience of customer verbal abuse was associated with a higher prevalence of depressive symptoms (PR: 1.37, 95% CI: 1.15-1.63). After being stratified by workload, customer verbal abuse showed a statistically significant association with depressive symptoms among high workload groups (PR: 1.46, 95% CI: 1.19-1.79), whereas the association was not statistically significant among low workload group (PR: 1.23, 95% CI: 0.91-1.65). Our findings suggest that experience of customer verbal abuse could have a negative influence on depressive symptoms among high-workload cosmetics sales workers in South Korea.
