The Effect of Postpartum Contraceptive Method Counselling on the Intention to Use Family Planning Methods

The aim of this study was to evaluate the effect of postpartum contraception counselling based on the health belief model on family planning attitudes and contraceptive method use intentions. The study was designed as a randomised controlled trial. The study population will consist of women who visited the postpartum ward at Zeynep Kâmil Women's and Children's Diseases Training and Research Hospital in Istanbul between March 2025 and November 2025. In the study, the sample size was calculated using the 'G. Power-3.1.9.2' programme at a 95% confidence level prior to the data collection phase. The study will evaluate the effect of motivational interviews based on the Health Belief Model on family planning attitudes and contraceptive use intentions. Accordingly, the scores from the 'Family Planning Attitude Scale' (difference between the intervention and control groups) used in Tavukçu's (2024) study were referenced for calculation (63). Accordingly, it was estimated that the minimum sample size required for 80% power at a significance level of 0.05 and an effect size of 0.794 would be 26 participants per group (total 52). Considering that a 20% loss may occur during the research process, the sample is planned to consist of 62 participants (intervention group = 31, control group = 31). Data collection will begin after the necessary institutional permission, ethics committee permission, and scale usage permissions have been obtained. A simple randomisation method will be used to randomly select individuals from the population and assign them to the intervention and control groups without bias. Volunteers who meet the inclusion criteria will be informed about the study and their consent will be obtained before randomisation. Using the computer-assisted https://www.random.org/integers/ programme, 31 participants will be assigned to the intervention group and 31 participants to the control group using a simple randomisation method.
