简要总结
A previous negative childbirth experience can increase fear and anxiety about giving birth again. This study aims to determine whether Gestaverso, a virtual reality-based childbirth preparation program, can help reduce fear of childbirth and improve the birth experience in pregnant women who have previously experienced a negative birth.
The study will include 124 pregnant women who have given birth at least once before and report a previous negative childbirth experience. Participants will be randomly assigned to one of two groups.
One group will receive an individualized childbirth preparation session using Gestaverso, a virtual reality program guided by a trained midwife. During the approximately 60-minute session, participants will experience a simulated childbirth journey, practice breathing and relaxation techniques, learn strategies for managing contractions, and become familiar with the hospital environment and different stages of labor. Their birth partner will also be encouraged to participate.
The other group will receive usual childbirth preparation provided by midwives, without virtual reality.
Participants will complete questionnaires about their fear of childbirth before the intervention and their childbirth experience after giving birth. The researchers will compare the results between the two groups to assess whether virtual reality-based childbirth preparation may help women with previous negative birth experiences feel more prepared for childbirth and have a more positive birth experience.
详细描述
A previous negative childbirth experience may contribute to increased fear and anxiety during subsequent pregnancies. Women who have experienced a distressing or traumatic birth may develop negative expectations about future childbirth, potentially affecting their emotional well-being and confidence in their ability to cope with labor.
Conventional childbirth preparation programs provide information about pregnancy, labor, pain management, and coping strategies. However, women with previous negative birth experiences may benefit from additional approaches that address the emotional aspects of childbirth and help them become familiar with the birth environment in a safe and controlled setting.
Virtual reality (VR) offers an immersive educational experience that allows pregnant women to become familiar with different stages of labor, practice coping strategies, and develop confidence in managing childbirth-related situations. Although VR has been investigated for pain and anxiety management during labor, its potential as a prenatal preparation tool specifically for women with previous negative childbirth experiences remains insufficiently explored.
Gestaverso is an immersive VR-based childbirth preparation program designed to simulate the childbirth journey, from the onset of labor at home to hospital admission, labor progression, and birth. The program combines visual, auditory, tactile, and sensory stimuli with professional guidance from a trained midwife.
This multicenter, randomized controlled trial will compare Gestaverso with usual childbirth preparation provided by midwives. Participants will be randomly allocated to two parallel groups in a 1:1 ratio.

研究组 & 干预措施
Gestaverso Virtual Reality Childbirth Preparation
Participants assigned to this arm will receive an individualized 60-minute childbirth preparation session using Gestaverso, an immersive virtual reality program guided by a certified midwife. The session consists of a 10-minute briefing, approximately 40 minutes of immersive simulation, and a 10-minute debriefing. The simulation recreates the childbirth journey, from the onset of labor at home to hospital admission, labor progression, and birth. Participants will practice breathing, relaxation, pelvic movement, non-pharmacological pain management strategies, and communication with healthcare professionals. Their birth partner will also participate in the experience and learn techniques to provide physical and emotional support during labor.
干预措施: Gestaverso (Behavioral)
Usual Childbirth Preparation
Participants assigned to this arm will receive usual childbirth preparation provided by midwives through group-based educational sessions, either in person or online, according to their preferences. The program consists of approximately 3 to 4 hours of education covering third-trimester symptoms, signs of labor, types of birth, contraction management, breathing techniques, and pelvic movement. Educational materials, recorded sessions, and support for questions will be available when needed. Participants will not receive virtual reality-based childbirth preparation.
干预措施: Control group (Behavioral)
结局指标
主要结局
Fear of Childbirth Assessed Using the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ)
时间窗: During pregnancy, before the intervention (baseline), and after childbirth (postpartum assessment), approximately 6-8 weeks from baseline.
The Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) will be used to assess fear of childbirth. The W-DEQ-A will be administered during pregnancy, before the intervention, to assess anticipatory fear of childbirth, while the W-DEQ-B will be administered after childbirth to assess the emotional experience of giving birth. Each version consists of 33 items scored on a 6-point Likert scale (0-5), with a total score ranging from 0 to 165. Higher scores indicate greater fear of childbirth or a more negative childbirth experience. Positively worded items are reverse-scored before calculating the total score. W-DEQ scores will be compared between the Gestaverso intervention group and the usual childbirth preparation group.
