Effects of Individual and Group Education on Mothers' Attitudes and Decisions About Childhood Vaccination

This study was planned to determine the effect of face-to-face and group education given to mothers regarding childhood vaccinations on their vaccination attitudes and decisions. It is believed that the education provided will help eliminate mothers' misconceptions and false beliefs about vaccines in the short term, and contribute to positive changes in their attitudes and decisions regarding vaccination. Moreover, it is anticipated that in the long term, this intervention will contribute to achieving better immunization rates and protecting children from vaccine-preventable diseases. This study is also important in terms of emphasizing the role of midwives in protecting and improving infant and community health.This study will be carried out as a randomized controlled experimental study to determine the effect of face-to-face and group education given to mothers regarding childhood vaccinations on their attitudes and decisions about vaccination. Mothers who have children within the age range in which childhood vaccinations are administered will be contacted and informed about the purpose and scope of the study, and they will be asked whether they agree to participate. Mothers who consent to participate will be randomly assigned into three groups using computer-assisted randomization (https://www.random.org/

): Group 1: Mothers receiving individual face-to-face education, Group 2: Mothers receiving group education, and Group 3: Control group (receiving the routine unit-based information).

About this study

Experimental Group 1

(Group 1: Mothers Receiving Individual Face-to-Face Education)

After identifying the mothers to whom the education will be provided, they will be contacted by phone using their contact information and informed about the study. Mothers who agree to participate will be invited to the Family Health Center (FHC). Before the education, the Data Collection Form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered.

The first session of individual face-to-face education will then be conducted using previously prepared educational content. An educational brochure related to the content of the training will be given to the mothers. After the education session, the data collection form, vaccine attitudes scale, and vaccine hesitancy scale will be administered again.

The second education session will be conducted two weeks later. In this session, the previously provided information will be reviewed and reinforced, and the mothers' questions will be answered. Following the session, the data collection form, vaccine attitudes scale, and vaccine hesitancy scale will be re-administered.

Experimental Group 2

(Group 2: Mothers Receiving Group Education)

After identifying the mothers to whom the education will be provided, they will be contacted by phone and informed about the study. Mothers who agree to participate will be invited to the FHC to attend group education sessions scheduled at appropriate dates and times. Before the education, the Data Collection Form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered.

The first session of the group education will be conducted using previously prepared educational content. An educational brochure related to the content of the training will be given to the mothers. After the education session, the data collection form, vaccine attitudes scale, and vaccine hesitancy scale will be administered again.

The second education session will be conducted two weeks later. In this session, the previously provided information will be reviewed and reinforced, and the mothers' questions will be answered. Following the session, the data collection form, vaccine attitudes scale, and vaccine hesitancy scale will be re-administered.

Control Group

(Group 3: Mothers Receiving Routine Education)

After identifying the mothers who will receive routine education at the FHC, they will be contacted by phone and informed about the study. The mothers will be invited to the FHC, where the Data Collection Form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered prior to the education.

Subsequently, the routine education provided by the FHC will be delivered, and an educational brochure will also be given to the mothers in the control group. After the education, the data collection form, vaccine attitudes scale, and vaccine hesitancy scale will be administered again.

Two weeks later, the mothers will be invited to the FHC again, the routine education will be repeated, and after the education, the data collection form, vaccine attitudes scale, and vaccine hesitancy scale will be re-administered.

Treatment and study plan

Vaccination attitude

Behavioral

This study was planned to determine the effect of face-to-face and group education given to mothers regarding childhood vaccinations on their attitudes and decisions about vaccination. It is thought that the education provided will help eliminate mothers' misconceptions and false beliefs about vaccines in the short term and contribute to positive changes in their attitudes and decisions regarding vaccination. Moreover, it is anticipated that, in the long term, this intervention will contribute to achieving better immunization rates and protecting children from vaccine-preventable diseases. This study is also important in terms of emphasizing the midwife's role in protecting and improving infant and community health.

Primary outcomes

  1. Vaccine Opposition Scale

    Time frame: 6 month

    The total score of the long form ranges from 21 to 105, while the total score of the short form ranges from 12 to 60. Higher scores on the scale indicate higher levels of vaccine hesitancy among participants."The long form of the scale demonstrated high internal consistency (Cronbach's alpha = 0.905)."

  2. Vaccine Attitudes Scale

    Time frame: 6 month

    Each item on the Vaccine Attitudes Scale is scored as agree = 1, undecided = 2, and disagree = 3. The total score is calculated by summing the item scores. The possible total score ranges from 11 to 33, where a score of 11 indicates a positive parental attitude toward vaccination, and a score of 33 indicates a negative attitude toward vaccination.

    The scale does not have a cut-off point. As the total score increases, parental vaccine hesitancy increases, reflecting a more negative attitude toward vaccination.

    "The Turkish version of the scale demonstrated acceptable internal consistency (Cronbach's alpha = 0.66)."

  3. Data Collection Form

    Time frame: 6 month

    This form was developed by the researcher and the advisor based on the relevant literature (Yorulmaz et al., 2024; Ünsal, 2020; Yiğit et al., 2020; Hazır, 2018) and consists of 27 questions. It will be used in the study to determine mothers' demographic and descriptive characteristics and their decisions regarding vaccination.
