The present study was designed to examine the structural relationship between mothers' perceptions of their relationships with their parents and husbands (as the predictors of parenting self-efficacy), mothers' parenting self-efficacy (PSE), and parenting behaviors among contemporary Korean mothers. A sample of 95 Korean mothers of pre-school,1st, 2nd, and 3rd grade elementary school children in Seoul, South Korea were recruited. Mothers were asked to respond to a survey that captured mothers' perceptions of their relationships with their parents and husbands, PSE, and their parenting behaviors. Structural equation modeling(SEM) was applied to analyze the hypothesized model. The results indicate that mothers who perceive their relationships with their own parents as positive were more likely to have higher PSE. In addition, mothers who reported higher PSE levels were less likely to be inconsistent in their parenting behaviors and more likely to be responsive in their parenting behaviors. The results of this study underscore the importance of PSE as a psychological resource that enables contemporary Korean mothers to parent in positive ways. Furthermore, these findings emphasize the importance of mothers' perceptions of their social relationships as a factor that contributes to higher PSE.
