Pregnancy usually lasts about 40 weeks or just over 9 months as measured from the last menstrual period to delivery. The experience of childbirth is always linked with emotional feelings and expectations. Objective: The aim of the study was to assess the effectiveness of childbirth education on knowledge and childbirth experience among primigravida women Methods: A quasi-experimental design was used to assess the effectiveness of childbirth education on knowledge and childbirth experience among primigravida women in Kamla Nehru Hospital, Shimla. In this study Pre-test and Post-test control group design, 50 primigravida women (25 in the experimental group and 25 in the control group), gestational age of 36- 38 weeks. Self Structured knowledge questionnaire to assess the knowledge and childbirth expectancy was measured by using Wijma Delivery expectancy questionnaire (scale-A) before the intervention in both group and childbirth experience was measured by using Wijma delivery experience questionnaire (scale-B) was used for data collection. Data was collected by structure interview schedule and analyzed by using descriptive and inferential statistics. Results- In experimental group pre-test mean±SD knowledge score was (8.60±1.38) and post-test mean±SD knowledge score was (14.12±1.81). The difference between pre-test and post-test mean±SD knowledge score was highly significant p=0.001. In the control group pre-test mean±SD knowledge score was (9.00±1.38) and post-test mean±SD knowledge score was (9.24±1.39). The difference between pre-test and post-test mean knowledge score was statistically non-significant. childbirth expectancy score of the experimental group was found to be (75.00±7.11) and the childbirth expectancy score of the control group was found to be (81.12±3.27). Whereas the childbirth experience score of the experimental group was found to be (60.40±2.87) and childbirth experience score of the control group was found to be (80.68±2.97) which was statistically significant at the level of 0.001. It was concluded that Childbirth education had an impact on knowledge and childbirth experience among primigravida women.
