The purpose of this study is to investigate the effects of gratitude and parenting stress in the relationship between neuroticism and postpartum depression.

155 respondents(mean age: 32.54 years) who were 4 weeks or more and 1 year or less postpartum completed surveys that measured levels of neuroticism, gratitude, parenting stress, and postpartum depression.

First, it shows that gratitude and parenting stress had partial mediating effect between neuroticism and postpartum depression each. Second, it was analyzed that gratitude and parenting stress had dual mediating effect between neuroticism and postpartum depression.

Based on the results of this study, it was confirmed that neuroticism could inhibit the development of gratitude, and that leads to an increase in parenting stress, leading to postpartum depression. Also, current results suggest that gratitude intervention and dealing with parenting stress in the treatment and prevention of postpartum depression is important. This paper includes limitations, implications, and suggestions for the future study.
