Objectives: Despite the fact that cesarean delivery does not offer significant health benefits for either mother or newborn, there has been a noticeable upward trend in elective cesarean births in Iran, over the last two decades. This study aims to examine whether knowledge, perception of health threats, efficacy, and personal beliefs act as psychological predictors towards the intention of women to have a normal vaginal delivery. Methods: The mixed-method approach was used as quantitative and qualitative design. Simultaneously, 290 pregnant women who visited prenatal clinics participated in the study. Quantitative and qualitative data were collected using a structured questionnaire based on Witte's Extended Parallel Process Model, and four focus groups, respectively. Results: Women perceived lower personal risk but higher levels of efficacy. Perceived self-efficacy, severity, and response efficacy emerged as significant predictors of intention to experience vaginal birth. The participants' insufficient knowledge and misconceptions about birth methods were prevalent. Major themes were identified and divided into negative and positive beliefs about vaginal birth. Conclusion: This educational model is useful for understanding women's intention to undergo a vaginal birth, especially when it is combined with a qualitative approach. Maternal care providers should acknowledge their clients' beliefs and intended childbirth methods prior to offering medical intervention.
