Background: Despite the advantages of natural childbirth and complications associated with cesarean section, rate of cesarean delivery had increased dramatically in recent years. Therefore, educational program is essential to reduce this trend. Aim of study: Was to evaluate the effect of educational program based on health belief model regarding safe childbirth on selected mode of delivery among primigravidae. Design: Quasi - experimental design was used to conduct this study. Setting: The study was conducted at out-patient clinic at Obstetrics and Gynecological department in Benha University Hospitals. Sample: A purposive sample of 300 women divided into two equal groups (study group=150 women who received educational program based on health belief model regarding safe child birth and control group= 150 women who received routine hospital care. Tools: Three tools of data collection were used, a structured interviewing questionnaire, Champion's health belief model scale and women's choice mode of delivery sheet. Results: There was an increase in total mean score of five constructs of health belief model toward vaginal and cesarean delivery in study group compared to control group with highly statistically significant differences after educational program (P≤ 0.001). More than one third of study group pre educational program preferred vaginal delivery compared by more than half of study group post educational program. While less than two thirds of study group preferred cesarean delivery pre educational program compared by less than half post educational program. On the other hand, there were no statistically significant differences between control group pre and post educational program. Conclusion: The educational program based on health belief model had improved primigravidae's knowledge and health beliefs regarding mode of delivery and also improved the selection of vaginal delivery. Vaginal delivery was chosen more in study group after educational program compared by pre educational program. Recommendations: Health belief model could be used as a routine model in health care sitting to empower women with comprehensive information on the benefits and severity of the different modes of delivery.
