Background: Childbirth is a significant and unforgettable event in a woman's life. Many primiparous women face the process alone with lack of support, experiencing fear of the unknown, fatigue, lack of previous experience, fear of complications, and may be influenced by negative birth stories. Therefore, the aim of the current study was to evaluate effect of applying AIDET communication model and supportive care during labor on birth experience. Design: A quasi experimental research design (pretest / posttest non equivalent control group design) was adopted. The study was conducted at The current study was carried out at the fourth floor of obstetric and gynecological building in Al Gamaa hospitals which is affiliated to the general organization for teaching hospitals in Zagazig town El Sharquia government.- Sample: A convenience sample of 124 primiparous women in the beginning of active phase (cervical dilation of 4 cm). Tools: 1) Structured Interview Questionnaire Schedule 2) Numerical Pain Rating Scale (NPRS); 3) Anxiety Assessment Scale for Pregnant Women in Labor (AASPWL) 4) partograph; and 5) The birth satisfaction scale (BSS). Results: No significant differences were observed at 4 cm cervical dilatation. However, pain scores at 5 cm and 6 cm were significantly lower in the intervention group (p < .001). Anxiety levels at 6 cm were significantly reduced in the study group (p < .001), with a large effect size. Birth satisfaction scores were significantly higher among women receiving the intervention (p < .001). No significant difference was found in labor duration (p > .05).. Conclusion: It can be concluded from the current study that the AIDET communication model and supportive care had a positive impact on pain, anxiety, and birth satisfaction, but they did not significantly influence the duration of the labor process among primiparous women. Recommendations: Based on the findings of this study, the following are recommended: Implement the AIDET Framework as a Standard of Care: Hospital and unit managers in Egyptian maternity settings should formally integrate the AIDET (Acknowledge, Introduce, Duration, Explanation, Thank You) communication model into routine intrapartum nursing protocols. It should be recognized not as an optional courtesy but as a required clinical intervention for all primiparous women. Develop and Mandate Structured Training Programs: The Ministry of Health and Population, in collaboration with the Egyptian Nursing Syndicate, should develop a standardized training curriculum and workshops to educate labor and delivery nurses on the correct application of the AIDET model alongside supportive care techniques. Training should include simulation and role-playing for competency. Create a Supportive Work Environment.
