Background: Intrapartum professional midwifery support can improve the coping skills with the fear of childbirth and birth pain, increase the perception of the woman, and prevent negative experiences. However, there are relatively few studies supporting this postulation. Aims: To investigate the effects of supportive care given during labor on birth pain, birth fear, perception of midwifery care, oxytocin use, and delivery time. Patients and Methods: This is a quasi-experimental study. We collected the data between January and June 2019 in a province in Central Anatolia, Turkey. Primiparous 102 pregnant women were included in the study. However, we excluded five pregnant women from the intervention group and four pregnant women from the control group as emergency cesarean section developed. In total, 93 pregnant women, 46 in the continuous supportive care intervention group, and 47 in the usual intrapartum care control group were evaluated. The following tools were used to collect data: The Delivery Fear Scale, a Visual Analog Scale for perceived pain, the Scale of Women's Perception for Supportive Care Given During Labor, and labor outcomes information form. Results: The participants in the intervention group receiving continuous intrapartum supportive care had less fear of birth and lower birth pain in the active and transitional stages of labor, their midwifery care perception increased, and the duration of labor was shorter (P < 0.05). However, there was no significant difference in oxytocin use between the two groups at 95% confidence interval (-0.265-0.091) (p > 0.05, Cohen's d = 0.2). Conclusion: Pregnant women who received continuous intrapartum supportive care had less fear of birth and reduced labor pain in active and transitional stages of labor. In addition, with the continuous supportive care provided, the perception of midwifery care of the pregnant women increased and the duration of labor decreased. Therefore, midwifery care support should be provided to women throughout their labor and delivery process.
