The effects of cesarean birth information given in childbirth preparation classes on maternal postpartum reactions to unplanned cesarean delivery were examined. An experimental group received comprehensive cesarean birth information as part of standard childbirth preparation classes. The control group received a standard childbirth preparation class curriculum that included limited cesarean birth information. The control group reported a slight decline in pain intensity from 1-2 days to 6 weeks postpartum, whereas the experimental group showed no change over time. No differences between the two groups were found in perception of the birth experience, physical distress, self-esteem, functional status, feelings about the baby, or quality of the marital relationship. The lack of substantial differences between the groups may be due to the normalizing effect of the high cesarean birth rate and greater attention given to this method of childbirth by expectant parents and childbirth educators.
