BMC Pregnancy and Childbirth, 25(1), 941. https://doi.org/10.1186/s12884-025-08097-81471-2393https://hdl.handle.net/11268/16348Pregnancy-related anxiety affects a significant number of women and has adverse consequences for both mothers and children. Virtual reality has emerged as an innovative strategy in the field of mental health to address anxiety disorders. However, in the field of obstetric healthcare, it has mostly been used as a distraction tool. The aim of this research was to determine the effectiveness of an immersive virtual reality intervention in reducing pregnancy-related anxiety during the third trimester of pregnancy. A single-group pre-post quasiexperimental study was conducted with 73 pregnant women who participated in a prenatal education program at a health center in Madrid. The intervention consisted of an interactive and immersive simulation with virtual reality, which was carried out during the last trimester of pregnancy. Anxiety was measured before and after the intervention via the Pregnancy Related Anxiety Questionnaire (PRAQ-20). The data were analyzed using descriptive and inferential statistical tests, including logistic regression.engAttribution 4.0 Internationalhttps://creativecommons.org/licenses/by/4.0/Trastorno de ansiedadEmbarazoTerapia de Exposición Mediante Realidad Virtualjournal article10.1186/s12884-025-08097-8open accessSalud mentalEmbarazoInvestigación médicaGoal 3: Ensure healthy lives and promote well-being for all at all ages
