Abstract

Objectives: The purpose of this study was to test the mediating effect of depression in the relationship between emotional labor and quality of sleep among dental hygienists. Methods: A purposive sample of 224 subjects in Seoul and Gyeonggi-do Province was recruited for convenient sampling. Data were analyzed using descriptive statistics, correlation, and multiple regression using Baron and Kenny steps for mediation. Results: The mean scores for overall emotional labor, quality of life, and depression were $33.14{\pm}5.55$, $7.49{\pm}2.82$, and $19.20{\pm}10.45$, respectively. They were significantly correlated with each other. Depression had a mediating effect(${\beta}=.52$, p<.001) in the relationship between emotional labor and quality of sleep(Sobel test: Z= 6.82, p =.001). Conclusions: The findings of this study suggest that intervention programs focusing on preventing depression are highly recommended to improve quality of life among dental hygienists in relation to emotional labor.
