An interventional study of Effect of Transtheoretical Model-Based Counseling on Postpartum Contraceptive Uptake in Birth Control Behavior and Reproductive Health Attitude, sponsored by Istanbul University - Cerrahpasa. Completed at 2 sites in Turkey (Türkiye). Open to female participants aged 18 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-25.

The purpose of this study is to evaluate the effect of contraceptive method counseling offered to primiparous women between the ages of 18-45 in the postpartum period by motivational interviewing method based on the Transtheoretic model, on the use of contraceptive methods.
Family planning (FP) is a practice that allows individuals to protect themselves from unwanted pregnancies, to regulate the period between pregnancies, to have children whenever and however they want, and to allow individuals who cannot have children to have children. Contraceptive methods make significant contributions to the protection and improvement of women's and children's health, as well as the health of society, by preventing excessive fertility, which negatively affects the health of mothers and babies. Therefore, effective provision of FP services makes significant contributions to the health of both women, children and society.
Unmet FP services can cause unwanted pregnancies, which can be a significant medical, social and sociological problem. According to the World Health Organization, approximately 75 million unintended pregnancies occur annually, and 65% of these pregnant women either do not use any contraceptive method or use a traditional method. An average of 25 million unsafe abortions occur annually and approximately 47,000 women die for this reason.
According to the results of the Turkey Demographic and Health Survey 2018 (TDHS 2018), only 49% of women in Turkey use a modern contraceptive method, while 30% do not.
they do not use any method and 12% of women have unmet need for FP services (TNSA 2018). The use of modern methods in Turkey
The relatively low number of FP services and the high number of unmet FP services still pose a significant problem in terms of women's health. Various complications such as uteroplacental bleeding, rupture, preterm birth, low birth weight, stillbirth and maternal abortion increase in women who become pregnant again less than 12 months after birth. If couples could extend pregnancy intervals beyond 2 years, 30% of maternal deaths and 10% of child deaths would be reduced.
It is stated that it can be prevented.
The unmet need for FP in women in the postpartum period is higher than in all married women. The postpartum period requires women to cope with increased stress, financial hardship, and the challenges of caring for their infants and older children. These difficulties may cause women to neglect their own health care. Although women are willing to use a contraceptive method, they may not be able to choose the appropriate method because they are not conscious of which method to use. For this reason, contraceptive method counseling given to women in the postpartum period is of great importance.
The Transtheoretic Model is a model of intentional change and focuses on the individual's decision-making process. According to the model, in order to direct the desired behavioral change, it is necessary to take initiatives appropriate to the stages of change that the individual is in. In this study, the effect of contraceptive method counseling based on the Transtheoretical model on postpartum women between the ages of 18-45 will be evaluated.

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

The study included women aged 18-45 who had given birth for the first time (primiparous), were within 72 hours of delivery and at the stage of discharge, and were considering using a contraceptive method in the future. A total of 80 women meeting the sampling criteria were randomly assigned to either the intervention group (n=30) or the control group (n=50). While the intervention group received contraceptive counseling based on the Transtheoretical Model.
Behavioral: Effect of Transtheoretical Model-Based Counseling on Postpartum Contraceptive Uptake
The control group received routine postpartum care services at the clinic.
The study included women aged 18-45 who had given birth for the first time (primiparous), were within 72 hours of delivery and at the stage of discharge, and were considering using a contraceptive method in the future. A total of 80 women meeting the sampling criteria were randomly assigned to either the intervention group (n=30) or the control group (n=50). Data collection forms were completed through face-to-face interviews. While the intervention group received contraceptive counseling based on the Transtheoretical Model, the control group received routine postpartum care services at the clinic. Contraceptive method usage was assessed via telephone at the 6- and 12-month marks for both groups, and at the end of the 12-month period, the "Contraceptive Methods Knowledge Test" (KYIBT) was administered to measure knowledge regarding contraceptive methods.
34-Question Family Planning Attitude Scale
A minimum of 34 points and a maximum of 170 points can be obtained from the scale. A high score from the scale indicates that the individual's attitude towards Family Planning is positive.
Time frame: Throughout the approximately one-year period during which the study was conducted
Knowledge Test on Contraceptive Methods
It was prepared by researchers and consists of 10 questions designed to evaluate women's knowledge levels about contraceptive methods, and the maximum score that can be obtained from the test is 10.
Time frame: Throughout the approximately one-year period during which the study was conducted
Plan to share: Yes — Following the statistical analysis of the study results, they will be presented in the form of a statistical analysis report.

Ran from Dec 2021 to primary completion in Jun 2024, 29 months.
Of 741 non-industry interventional studies with no phase under Behavior, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 32. This study's 29 months is above that.
Counting every sponsor, half of 757 studies reached it within 13 months; a quarter within 5 and three quarters within 32.
