Brief Summary

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).

Outcome Measures

Primary Outcomes (3)

• Vaccine Opposition Scale

  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)."

  6 month

• Vaccine Attitudes Scale

  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)."

  6 month

• Data Collection Form

  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.

Study Arms (3)

Group 1: Mothers receiving individual face-to-face education

EXPERIMENTAL

After identifying eligible mothers, they will be contacted by phone and informed about the study. Mothers who agree to participate will be invited to the Family Health Center (FHC). Before the training, the Data Collection Form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered. The first session of individual face-to-face education will be conducted using pre-prepared training content. An educational brochure related to the training content will be provided. After the session, the same forms and scales will be re-administered. Two weeks later, a second individual training session will be conducted to review and reinforce the previous education, and mothers' questions will be answered. Following the session, the data collection form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered again.

Behavioral: Vaccination attitude

Group 2: Mothers receiving group education

EXPERIMENTAL

After identifying eligible mothers, they will be contacted by phone and informed about the study. Mothers who agree to participate will be invited to the Family Health Center (FHC) on scheduled dates for group training sessions. Before the training, the Data Collection Form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered. The first group education session will be conducted using pre-prepared training content, and an educational brochure will be provided. After the session, the same forms and scales will be re-administered. Two weeks later, a second group education session will be conducted to review and reinforce the previous education, and participants' questions will be answered. After the session, the data collection form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered again.

Behavioral: Vaccination attitude

Group 3: Control group (receiving the routine unit-based information)

NO INTERVENTION

After identifying mothers who will receive routine informational training at the Family Health Center (FHC), they will be contacted by phone and informed about the study. Mothers who agree to participate will be invited to the FHC. Before the routine training, the Data Collection Form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered. Routine training provided by the FHC will then be conducted. After the training, the same data collection form and scales will be re-administered. Two weeks later, participants will be invited again to receive routine training once more, and following the training, the Data Collection Form, Vaccine Attitudes Scale, and Vaccine Hesitancy Scale will be administered again.
