Vaccine uptake
Percentage(%) of participants who have received at least one dose of HPV vaccine, assessed by self-reported vaccination history
Vaccine knowledge
Vaccine knowledge will be measured based on participants' scores on the vaccine knowledge items included in the study questionnaire, which will assess general vaccine knowledge and HPV vaccine-specific knowledge. Responses to individual items will be scored according to the predefined scoring criteria and summed to generate domain-specific knowledge scores. Higher scores indicate greater knowledge in the corresponding domain.
Vaccine attitude
Vaccine attitudes will be measured based on participants' scores on the Vaccination Attitudes Examination Scale included in the study questionnaire, which assesses four dimensions of vaccination attitudes: mistrust of vaccine benefits, worries about unforeseen future effects, concerns about commercial profiteering, and preference for natural immunity. Responses to individual items will be scored according to the predefined scoring criteria and combined to generate an overall vaccine attitude score. Higher scores indicate more negative attitudes toward vaccination.
Vaccine confidence
Vaccine confidence will be measured based on participants' scores on the Vaccine Confidence Index included in the study questionnaire, which assesses perceptions of vaccine importance, safety, effectiveness, and compatibility with religious beliefs. Responses to individual items will be scored according to the predefined scoring criteria and combined to generate an overall vaccine confidence score. Higher scores indicate greater confidence in vaccines.
Vaccine hesitancy
Vaccine hesitancy will be measured based on participants' scores on the Vaccine Hesitancy Scale included in the study questionnaire. The scale assesses participants' perceptions of vaccine importance and effectiveness, trust in vaccine information and recommendations, perceived benefits of vaccination, and concerns about vaccine risks and adverse effects. Responses to individual items will be scored according to the predefined scoring criteria and summed to generate a total vaccine hesitancy score. Higher total scores indicate greater vaccine hesitancy.
