Abstract: This study has been attempted to identify the effects of educational program on pre and postpartum self-care and parenting knowledge and efficacy in married immigrant women in South Korea. The data collection period and pre and postpartum self-care and parenting educational program were between April 4 and August 27, 2016. Twenty married immigrant women participated in 4 times parenting educational programs. Data were analyzed using frequency analysis, paired t-test and Cronbach’s alpha coefficients with the SPSS 18.0 for windows program. Following the programs there were significant increased in knowledge on pre and postpartum self-care (t = -2.31, p = 0.033) and parenting knowledge (t = -277, p = 0.012) and parenting efficacy t = -6.71, p<0.001). The correlation between the pre and postpartum self-care knowledge, parenting knowledge and parenting efficacy in the subjects showed that there was a highly positive correlation between the pre and postpartum self-care knowledge and parenting knowledge (r = 0.741, p<0.001), the pre and postpartum self-care knowledge and parenting efficacy (r = 0.797, p<0.001) and the parenting knowledge and parenting efficacy (r = 0.934, p<0.001). Various studies need to be performed to develop programs that can promote pre and postpartum self-care and parenting knowledge and parenting efficacy for this population by reducing the difficulties they face.
