The purpose of this study was to examine the trajectories of the mother’s parenting stress and to identify predictors using latent growth modeling(LGM) and to compare the effects of the first wave predictors(mother’s self efficacy, child’s emotional temperament, father’s participation in child care, social support) on the trajectories. In order to accomplish these purposes, analysis was conducted using the 1st~6th wave of longitudinal panel data set of 2,078 families from the PSKC(Panel Study of Korean Children) beginning in 2008 by KICCE(Korea Institute of Child Care and Education). The latent growth curve model was used to examine the mother’s parenting stress during her child’s age from 0 to 5 year old. The main results of this study were as follows. First, there was a non-linear increase in mother’s parenting stress over the course of 5 years. Over time, parenting stress is increased but growth rate is gradually relaxed. In addition significant individual differences in the trajectories(intercept and slope) were found. Second, the predictors had significant effects on the trajectory of mother’s parenting stress. The trajectory of mother with lower self-efficacy, lack of social support and child’s higher emotional temperament showed higher intercept and increased fast.
