Midwife-Led Antenatal Perineal Massage Education in Primiparous Pregnant Women

This controlled quasi-experimental study will evaluate the effect of a structured midwife-led antenatal perineal massage education program on pregnancy empowerment, self-efficacy for normal birth, and fear of childbirth among primiparous pregnant women. The study will be conducted at the Obstetrics and Gynecology Outpatient Clinic of Silifke State Hospital in Mersin, Turkey, after ethics committee approval.

The study population will consist of pregnant women attending the Obstetrics and Gynecology Outpatient Clinic of Silifke State Hospital. Eligible participants will be women aged 18-35 years who are at least primary school graduates, able to communicate in Turkish, between 28 and 34 weeks of gestation, primiparous, carrying a singleton pregnancy, planning a vaginal birth, able to use a smartphone, and have internet access. Women with an indication for planned cesarean section, a history of perineal surgery, an active genital infection or lesion, or cognitive, communication-related, or psychiatric conditions that prevent completion of study forms will be excluded.

The planned sample size is 152 pregnant women, with 76 participants in the intervention group and 76 participants in the control group. The sample size was calculated using G*Power version 3.1.9.7 based on a two-tailed test, a significance level of 0.05, statistical power of 80%, and an assumed medium effect size of Cohen's d = 0.50. The minimum required sample size was calculated as 64 participants per group, and the target sample size was increased to 76 participants per group to account for potential attrition or missing data.

Participants in the intervention group will receive structured midwife-led antenatal perineal massage education in addition to routine antenatal care. The educational content will include the importance of pelvic health, preparation for antenatal perineal massage, antenatal perineal massage technique, and maintenance of pelvic health. The intervention is intended to improve women's knowledge and practice of antenatal perineal massage and to support empowerment, confidence regarding normal birth, and reduction of fear related to childbirth. Participants in the control group will receive routine antenatal care provided at the study hospital.

Data will be collected using a Participant Information Form, the Antenatal Perineal Massage Knowledge and Preference Form, the Pregnancy Empowerment Scale, the Self-Efficacy Scale for Normal Birth, the Childbirth Attitudes Scale, and the Antenatal Perineal Massage Follow-up Form. The primary outcome will be change in pregnancy empowerment. Secondary outcomes will include change in self-efficacy for normal birth, change in fear of childbirth, antenatal perineal massage knowledge and preferences, and adherence to antenatal perineal massage practice.

Baseline data will be collected before the intervention. Post-intervention data will be collected after completion of the antenatal perineal massage education and follow-up period, according to the study protocol. The study is planned to be conducted between May 15, 2026 and December 31, 2026.
