This study intends to identify the relations among labor pain and labor agentry of puerperas giving birth in midwifery clinic and perception of delivery experience, and to establish factors influencing on their perception of delivery experience. Methods: Descriptive survey research. Data were collected from puerperas giving birth through vaginal delivery in six midwifery clinics, and they were analyzed through t-test, ANOVA, pearson's correlation coefficients, and stepwise multiple regression. Results: Figures of labor pain of puerperas giving birth in midwifery clinic by stage were 4.12, 6.80 and 8.11 in average in latent, active and transitional stage, respectively, while labor agentry and perception of delivery experience showed upper-middling figures, namely 3.70 and 3.94. It was revealed that labor agentry of puerperas giving birth in midwifery clinic had negative correlation with labor pain in latent stage (r=-0.176, p=0.021). Perception of delivery experience had the same with labor pain in latent stage (r=-0.177, p=0.020) and labor pain in active stage (r=-0.159, p=0.037), whereas perception of delivery experience had positive correlation with labor agentry (r=0.750, p<0.001). In addition, factors influencing on perception of delivery experience of puerperas giving birth in midwifery clinic were labor agentry, educational background and marital satisfaction, accounting for 58.8%. Conclusion: The results suggest that developing and applying nursing intervention program that increases labor agentry so that puerperas giving birth in midwifery clinic may perceive childbirth experience positively.
