Objectives: The aim of this study was to examine factors influencing depressive symptoms among married working women using the dataset of the Korean Longitudinal Survey of Women and Family (KLoWF 7th). There were 1,030 subjects. Methods: A multiple regression model was used to study the factors influencing depressive symptoms among married working women. Results: The authors found a negative relationship between satisfaction with spouse household-labor (b=-0.606, p=0.022) and depressive symptoms among married working women, a negative relationship with spouse (b=-0.237, p<0.001) and a negative spousal perception of working (b=-0.709, p=0.045), a positive relationship with excessive working hours (b=0.397, p=0.027), a positive relationship with temporal oppression on workload (b=0.422, p=0.002), and a positive relationship between workplace discrimination (b=0.053, p=0.046) and depressive symptoms among married working women. Conclusions: This study suggests that family life and working environments are important factors for depressive symptoms in married women workers. The findings of this study will be helpful to policymakers to design plans to decrease depressive symptoms among married working women.
