  Abstract: Objective: To investigate the impact of nursing interventions based on the PERMA model on adverse emotions in primiparous women. Methods: From February 2024 to August 2025,120 primiparous women admitted to the obstetrics department of our hospital were selected as research subjects. The participants were randomly divided into an observation group and a control group (60 cases each) using a random number table. The control group received routine obstetric care, while the observation group underwent nursing interventions based on the PERMA model. The study compared adverse emotions, childbirth self-efficacy, labor progression, delivery outcomes, and maternal satisfaction between the two groups before and after intervention. Results: After intervention, the observation group showed significantly lower anxiety scores (SAS: 38.69±2.96 vs 45.10±3.44) and depression scores (SDS: 37.89±3.85 vs 42.55±3.41) than the control group (both P<0.001). The observation group also demonstrated significantly higher total self-efficacy in childbirth (258.74±7.96 vs 212.74±8.10) (P<0.001). Notably, the observation group experienced shorter first, second, and total labor duration, with a significantly higher natural delivery rate (75.00% vs 50.00%) (P<0.01). Additionally, the cesarean section rate and postpartum hemorrhage rate were lower (all P<0.05), while the maternal satisfaction rate with childbirth (98.33% vs 80.00%) showed a significant improvement (P<0.001). Conclusion: Nursing interventions based on the PERMA model can effectively alleviate adverse emotions in primiparous women, enhance maternal self-efficacy, shorten labor progression, prevent adverse pregnancy outcomes, and improve maternal satisfaction during childbirth.
