The aim of this study is to evaluate the effects of midwife-guided birth affirmation cards on labor duration, pain level, fear of childbirth, perceived control, and perceived support in primigravidas. The study seeks to determine whether this non-pharmacological approach used during labor improves the childbirth experience. Accordingly, the research aims to answer the question: "Do midwife-guided birth affirmation cards affect labor duration and the childbirth experience, including pain, fear, perceived control, and perceived support, in primigravidas?"

This study is designed to investigate the use of birth affirmation cards, implemented under midwife guidance, as a non-pharmacological, low-cost, and feasible approach to support the labor process in primigravid women. Labor is not only a physiological process but also a multidimensional experience involving cognitive, emotional, and behavioral responses. Supporting a woman's sense of safety, enhancing coping capacity, and promoting a positive perception of childbirth are critical for improving the overall quality of the birth experience.

Birth affirmation cards are structured tools consisting of brief, positive, and empowering statements aimed at activating internal resources, strengthening self-efficacy, and fostering a positive cognitive framework toward childbirth. The implementation of these cards under midwife guidance ensures not only the delivery of supportive content but also continuous professional support, encouraging the active participation of the woman throughout labor. Therefore, the intervention is expected to contribute not only to psychological comfort but also to improved coping ability during childbirth.

The study will be conducted using a randomized controlled trial design. Participants allocated to the intervention group will receive midwife-guided birth affirmation card support during labor, while the control group will receive standard institutional care. The intervention content is structured around themes such as adaptation to labor, relaxation, confidence, resilience, trust in the body's ability to give birth, and the promotion of a positive childbirth perception. During implementation, the midwife will provide verbal support using the cards in accordance with the clinical condition of the participant and the stage of labor.

The innovative aspect of this study lies in evaluating birth affirmation cards not merely as individual psychological tools but as a structured, midwife-led supportive care intervention. Although existing literature highlights the importance of fear of childbirth, pain perception, perceived control, and perceived support in shaping the childbirth experience, randomized controlled studies examining the combined effects of affirmation-based interventions on these outcomes remain limited. Therefore, this study is expected to contribute to evidence-based midwifery practices and support the development of woman-centered supportive care strategies in labor.

The findings of this study are anticipated to support the integration of easily applicable, cost-effective, and potentially satisfaction-enhancing supportive care practices into routine maternity care. Additionally, promoting a positive childbirth experience may contribute to improved maternal psychological well-being and enhance the visibility and professional role of midwives in intrapartum care.
