Purpose: This study was conducted to develop a postpartum care program and to evaluate the effects of the program on postpartum activity and postpartum discomfort in primiparous women. Methods: For this control group quasi-experimental study, primiparous women who had a normal delivery at OBGYN clinics in G-city and then went home with assistance from their mothers participated from April 10 to August 2, 2006. The participants were assigned to an intervention group of 25 mothers or a control group of 23 mothers. Data analysis was performed by using SPSS/win10.0 PC+. $X^2$-test and t-test, and repeated measure ANOVA. Results: The results showed that the degree of postpartum activity(F=4.66, p=.036) and the degree of postpartum discomfort(F=7.98, p=.007) were supported statistically with significant differences between the two groups. Conclusions: Therefore, this program needs to be applied as a new nursing intervention because this postpartum care program was proven useful as effective postpartum care.
