Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This research will be carried out as a randomized controlled study with a waitlist in parallel design to evaluate the effect of Supportive Vaccine Communication using Motivational Interviewing on the level of vaccination literacy, vaccine knowledge, and vaccine decision thought. Research hypothesis "H0: Supportive Vaccine Communication using Motivational Interviewing does not affect vaccine decision processes (vaccine literacy, vaccine knowledge, and vaccine decision thought). At the end of the training, it is thought that the pregnant mothers in the experimental group will be different from the control group regarding vaccine literacy, vaccine knowledge, and vaccine decision-making thoughts included in the model.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In determining the sample size in the study, the smallest effect size value obtained for the Vaccine Literacy Scale result in a doctoral thesis based on another model on non-pregnant mothers in the same region was taken into consideration. In this thesis, the partial eta-squared value for Critical Vaccine Literacy was determined 0.260 (Yorulmaz, 2024). For this value, 95% power and 0.05% alpha type error margin and the total sample size required to estimate the interaction effects were determined as 48. Considering the sample losses, the sample was increased by 20% (9.6 people \~ 10 people), and a total of 58 people, 29 of which were experimental and 29 control, was determined. Pregnant mothers who apply to the obstetrics and gynecology clinic of the hospital's, which are research areas, will be evaluated according to the eligibility criteria. Then, a surveyor will obtain contact information from pregnant mothers, who met the inclusion criteria, volunteered for the study, and consented, and collect pre-test. In the study, pregnant mothers will be stratified as primiparous pregnant women (first pregnancy) and multiparous pregnant women (2 and more pregnancies). Participants will be divided into experimental and control groups using blind technique, stratification, and block randomization. The supportive vaccination communication using prepared on the motivational interview method for the pregnant mothers in the experimental group will be face-to-face training. The training will be in the form of 3-part and 6-sessions (with a 1-week interval) as group training for 3-5 people, and each session will last 40 minutes on average. After the Supportive Vaccine Communication process of the pregnant mothers in the experimental group is completed, the data collection forms will be applied again to the pregnant mothers in the experimental and control groups. After the last measurement, a 3-part, and 6-session supportive vaccine communication process will be applied to the pregnant mothers in the control group in the same way and within the same scope as the experimental group.

The primary outcome expected from the study is the change in pregnant mothers' vaccine literacy, vaccine knowledge, and vaccine decision thought.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Random assignment. Block randomization will be used in the randomization process. Randomizer.org will be used to select block combinations with six blocks. Pregnant mothers will first be stratified according to their number of pregnancies. Eligible participants will be randomly assigned to the intervention or waitlist group using the permuted block randomization method on a 1:1 basis. The waiting list group will form the second set of the research, which is planned to be attempted two months later. The participant assignment list will be generated by a non-research statistician with a random distribution sequence. Assignment confidentiality will be ensured using opaque sealed envelopes containing sequence numbers. The data analyst/statistician will be blind to the participants' group assignments.

Blinding Strategy

SINGLE

Participants
Single blinding(Participant blinding) will be done; participants will not be told they are in the experimental or control group. A surveyor will invite pregnant mothers to the study, which will continue until the targeted sample number (58 participants) is reached. During the participant registration, the names and contact information of the mothers will be obtained; it will be stated that they will be contacted for the training process, that the training time may be extended, and that they will be given definite training. The participant registration is completed, the supportive vaccine communication process will begin. The second researcher(D-KT) in the research team will explain to the first researcher(DS-Y) that the participants are in the experimental or control group. The pregnant mothers in the control group will be assigned to the waiting list.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

experimental

Supportive Vaccine Communication using Motivational Interviewing will be administered to the pregnant mothers in the experimental group by the researcher. The training will take place in 3-part and 6-sessions, one week apart, and each session will last approximately 40 minutes. The training will be carried out as group training with 3-5 people. Data collection forms will be applied before and after the program.

Group Type EXPERIMENTAL

Supportive Vaccine Communication Using Motivational Interviewing

Intervention Type OTHER

Supportive Vaccine Communication using Motivational Interviewing will be administered to the pregnant mothers in the experimental group by the researcher. The training will take place in 3-part and 6-sessions, one week apart, and each session will last approximately 40 minutes. The training will be carried out as group training with 3-5 people. Data collection forms will be applied before and after the program.

control

No intervention will be made to the pregnant mothers in the control group during the education process of the experimental group. After the training process of the pregnant mothers in the experimental group is completed and the post-test data are collected, all the interventions and training will be given to the pregnant mothers in the control group.

Group Type NO_INTERVENTION
