About this study

Official title: The Effect of Vaccine Education Program Based on The Integrated Change Model on Vaccine Advocacy and Vaccine Literacy: A Waitlist Randomized Controlled Trial

This research will be carried out as a randomized controlled study with a waitlist in parallel design to evaluate the effect of the vaccine education and vaccine advocacy program prepared according to The Integrated Change Model on the level of vaccination literacy and the transformation into vaccine advocates. Research hypothesis "H0a: Vaccine education program prepared according to The Integrated Change Model does not affect vaccine literacy, H0b: The vaccine training program prepared according to the integrated change model does not affect the concepts (information sources, intention, attitude, behavior, obstacles) in the integrated change model determined for vaccine advocacy. At the end of the training, it is thought that the mothers in the experimental group will be different from the control group regarding vaccine literacy and the vaccine advocacy concepts (information sources, intention, attitude, behavior) in the model.

Read the detailed description

This research will be carried out as a randomized controlled study with a waitlist in parallel design to evaluate the effect of the vaccine education and vaccine advocacy program prepared according to The Integrated Change Model on the level of vaccination literacy and the transformation into vaccine advocates. Research hypothesis "H0a: Vaccine education program prepared according to The Integrated Change Model does not affect vaccine literacy, H0b: The vaccine training program prepared according to the integrated change model does not affect the concepts (information sources, intention, attitude, behavior, obstacles) in the integrated change model determined for vaccine advocacy. At the end of the training, it is thought that the mothers in the experimental group will be different from the control group regarding vaccine literacy and the vaccine advocacy concepts (information sources, intention, attitude, behavior) in the model.

A national study on the subject was used in calculating the study's sample size. In a study conducted in Turkey, the rate of those who were hesitant about vaccination in the families of children under five years old and the rate of rejection was found to be 19.8% (1). The sample size required to eliminate this situation with vaccine advocacy was calculated as a total of 64 individuals at 0.05 alpha and 80% power level in the Gpower program. Considering the sample losses, the sample was increased by 15% (9.6 people ~ 10 people), and a total of 74 people, 37 of which were experimental and 37 control, was determined. Mothers who applied to the Family Health Centers, which are research areas, will be evaluated according to the eligibility criteria. Then researcher (DS-Y) will obtain contact information from mothers, who met the inclusion criteria, volunteered for the study, and consented, and collect pre-test. The participants will be divided into experimental and control groups using the blind technique and block randomization. The vaccination training program prepared based on The Integrated Change Model for the mothers in the experimental group will be face-to-face training. The training will be in the form of 4 sessions (with a 1-week interval) as group training for 4-5 people, and each session will last 45 minutes on average. After the training program of the mothers in the experimental group is completed, the data collection forms will be applied again to the mothers in the experimental and control groups. After the last measurement, a 4-session vaccination training program will be applied to the 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 mothers' vaccine literacy, vaccine advocacy intention, and vaccine attitudes.

The secondary result expected from the study is the change in mothers' knowledge of vaccination and sources of vaccination information.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Vaccine literacy

    The primary outcome expected from the study is the change in mothers' vaccine literacy, vaccine advocacy intention, and vaccine attitudes.

    Vaccine Literacy: Vaccine Literacy Scale Vaccine Literacy Scale: The scale evaluates the level of vaccine literacy. The Vaccine Literacy Scale was developed by Ahoran et al. (2017). The scale consists of 3 sub-dimensions and 13 items: Functional, Communicative, and Critical Health Literacy. The scores of the subscales are calculated separately; therefore, the scale has no total score. Responses in each subscale are divided by the number of items to obtain a score. Lower functional health literacy scores indicate higher health literacy. Higher communicative and critical health literacy scores indicate higher health literacy. The researchers previously carried out this scale's Turkish validity and reliability study (3).

    The results will be evaluated for each participant before and after the vaccine training (within 1 month on average).

    Measured: 01.08.2023-31.08.2023 (within 1 month on average)

  2. Vaccine advocacy intention

    Vaccine Advocacy Intention: Vaccine Advocacy Intent Scale

    Vaccine Advocacy Intention: Vaccine Advocacy Intent Scale Vaccine Advocacy Intent Scale: Mothers' vaccine advocacy intent will be evaluated with the Vaccine Advocacy Intent Scale. Researchers prepared the Vaccine Advocacy Intention Scale to assess mothers' intentions to engage in vaccine advocacy. The scale is scored between 0-10 points; an increase in the total score is interpreted as an increase in vaccine advocacy intention. The aim is to evaluate quantitatively mothers' intentions to be able to do vaccine advocacy.

    The results will be evaluated for each participant before and after the vaccine training (within 1 month on average).

    Measured: 01.08.2023-31.08.2023 (within 1 month on average)

  3. vaccine attitudes

    The Public Attitude Towards Vaccination Scale-Health Belief Model (PAVS-HBM): PAVS-HBM measure the public's attitude towards the vaccine according to the health belief model. The scale consists of 26 items and five sub-dimensions: sensitivity, severity, benefits, barrier, and health responsibility. Each sub-dimension is evaluated separately. Sensitivity and severity sub-dimension has four items (lowest4, highest20 points); benefit and health responsibility sub-dimension consists of five items (lowest5, highest25 points), and the barrier sub-dimension consists of eight items (lowest8, highest40 points). While the decrease in the total score in the disability sub-dimension indicates a positive attitude. An increase in the total score in other sub-dimensions means a positive attitude (4).The results will be evaluated for each participant before and after the vaccine training (within 1 month on average).

    Measured: 01.08.2023-31.08.2023 (within 1 month on average)

Secondary outcomes (2)
  1. Vaccine knowledge level and sources of vaccine information

    The secondary result expected from the study is the change in mothers' knowledge of vaccination and sources of vaccination information.

    Vaccine knowledge: Vaccine Knowledge Test Vaccine Knowledge Test: Researchers conducted Vaccine Knowledge Test by reviewing the literature to evaluate mothers' knowledge about vaccines has been prepared (5-10). In the Vaccine Knowledge Test, there are 31 questions answered as true, false, and do not know. Expert opinion was taken while creating the Vaccine Knowledge Test, and the content validity was evaluated. The lowest score that can be obtained from the Vaccine Knowledge Test is 0, and the highest score is 31; The increase in the total score indicates that the vaccination knowledge is high.

    The results will be evaluated for each participant before and after the vaccine training (within 1 month on average).

    Measured: 01.08.2023-31.08.2023 (within 1 month on average)

  2. Sources of vaccine information

    Vaccine Information Resources: Vaccine Knowledge Resources Questionnaire

    Vaccine Knowledge Resources Questionnaire: Vaccine information resources of mothers will be evaluated with the Vaccine Information Resources Questionnaire. The researchers reviewed the Vaccine Information Resources Questionnaires to determine which sources mothers used as vaccine information sources in the literature (1, 11-14). There are eight questions in this form; The questions are answered with yes or no. After the training, mothers are expected to obtain information from reliable information sources such as WHO and UNICEF.

    The results will be evaluated for each participant before and after the vaccine training (within 1 month on average).

    Measured: 01.08.2023-31.08.2023 (within 1 month on average)

Model description
Randomization and blinding are recommended in randomized controlled studies to prevent biases and show the experiment's success (15). Allocation: Random assignment. Block randomization will be used in the randomization process. Randomizer.org will be used to select block combinations with eight blocks. 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.
