The independent variable was hypnobirthing. The anxiety level between the two groups was tested by Mann Whitney. Results : After intervention, pregnant mothers who received hypnobirthing had anxiety level as low as 41.33 (p=0.003). Pregnant mothers who did not receive hypnobirthing had anxiety level as low as 51.60 (p=0.003). The reduction of anxiety between the two groups was statistically significant. Conclusion : Hypnobirthing can effectively reduce anxiety among pregnant mothers during birth delivery.
