This randomized controlled trial aims to evaluate the effect of a mindfulness-based intervention on childbirth self-efficacy, fear of childbirth, and self-compassion among primiparous pregnant women. Eligible pregnant women will be randomly assigned to either a mindfulness intervention group or a control group receiving routine antenatal education and standard prenatal care. The intervention program will consist of eight sessions delivered over four weeks. Outcomes will be assessed before and after the intervention using validated measurement tools. The findings may contribute to the development of effective psychosocial interventions to improve maternal well-being during pregnancy.
