  ABSTRACT: Background: To improve negative birth experiences among women who experience intense labor pain during labor, it is important to examine the relationship between fear of childbirth immediately after vaginal delivery and the actual intensity of labor pain. However, previous studies have generally evaluated labor pain in a retrospective setting. Purpose: This study examined the relationship between fear of childbirth immediately after vaginal delivery and the actual labor pain intensity and accumulated labor pain intensity without pharmacological pain relief during labor in Japan. Methods: A prospective observational study was conducted between July 2015 and April 2016. Forty-seven pregnant Japanese women were available for analysis. Fear of childbirth was measured by the Japanese version of the Wijma Delivery Expectancy/Experience Questionnaire (JW-DEQ) version B on the third day after vaginal delivery. Participants with scores of 85 or higher were categorized in the high JW-DEQ group, having severe fear of childbirth. Labor pain intensity was examined chronologically in real time with stepwise usage of two types of Numeric Rating Scale (NRS). Accumulated labor pain intensity was calculated using the area under the curve (AUC). Results: Nine participants were in the high JW-DEQ group and eight of the nine were primiparae. Primiparae in the high JW-DEQ group experienced significantly longer duration and larger accumulated labor pain intensity between the onset of labor and 4 to 6 cm of cervical dilatation than those in the low JW-DEQ group (P = 0.024 and P = 0.021, respectively). Conclusions/Implications for Practice: The latent phase of labor was a key stage to improve fear of childbirth immediately after vaginal delivery without pharmacological pain relief among Japanese primiparae. Midwives should give assistance in the latent phase of labor by focusing on progressing labor smoothly and relieving labor pain to improve negative birth experiences.
