Nursing Strategies to Increase Vaccination Rates in Adolescents: Education, Video Animation and Games
Nursing Strategies to Increase Vaccination Rates in Adolescents: Education, Video Animation and Games
Purpose: This study aims to evaluate how immunization education, video animation, and game interventions based on the Health Belief Model (HBM) affect the immunization decisions of late adolescents. The findings could contribute to the development of targeted interventions to increase vaccine acceptance among adolescents.
Hypotheses:
Does the educational intervention, video animation, and game application affect adolescents' knowledge of vaccines? Do these interventions influence adolescents' positive attitudes towards vaccines? Will the interventions lead to significant changes in adolescents' health beliefs, especially regarding perceived risks, benefits, and barriers? Do the interventions increase vaccine acceptance and vaccination rates among adolescents? Do the interventions reduce vaccine hesitancy among adolescents? Can the Health Belief Model-based interventions provide an effective communication strategy to increase vaccine acceptance?
Method:
The research will be conducted from March 3 to March 30, 2025. Participants will undergo immunization education, video animation, and game applications. Expert opinions will be consulted for developing educational materials, videos, and games. Institutional approval will be obtained, and an informed consent form will be distributed to participants. Those who volunteer will be assigned numbers, and participants for the intervention and control groups will be selected using simple random sampling.
Interventions:
Educational Material: Aimed at increasing awareness about vaccines, the education focuses on the perceived risks, benefits, and barriers to vaccination.
Video Animation: A video that explains how vaccines work, strengthen the immune system, and address perceived risks and benefits.
Game Application: A simulation game called "infected interaction," where participants learn about the spread of infectious diseases during social interactions.
Inclusion Criteria:
Inclusion: Adolescents aged 18-21, willing to participate, complete research forms, and attend the sessions.
Exclusion: Withdrawal from the study.
Variables:
Independent Variables: Gender, age, income, school, chronic illness, etc. Dependent Variables: Scale scores.
Data Collection Tools:
Adolescent Introductory Questionnaire: A form with 14 questions about demographic information and attitudes toward vaccination.
Vaccine Hesitancy Scale: A 9-item scale measuring vaccine hesitancy. Self-Efficacy Scale: A 23-item scale to assess adolescents' self-efficacy in various contexts.
Statistical Analysis:
Sample size was determined by power analysis: 210 participants (105 intervention, 105 control). Data will be analyzed using IBM SPSS Statistics V 26. Normal distribution will be assessed with the Shapiro-Wilk test, and homogeneity of variance will be tested with Levene's test. Pre- and post-test scores will be compared using repeated measures ANOVA. A p-value of <0.05 will be considered statistically significant.
Expected Outcomes:
Increased Knowledge: It is expected that educational interventions and video animations will improve adolescents' knowledge about vaccines, potentially influencing their attitudes.
Positive Attitude Change: The intervention may lead to more positive attitudes towards vaccination.
Changes in Health Beliefs: The intervention could alter adolescents' perceived risks, benefits, and personal beliefs regarding vaccines.
Increased Vaccine Acceptance: The study may demonstrate that these interventions increase vaccine acceptance and vaccination rates.
Effective Communication Strategies: The study may identify effective communication strategies for increasing vaccine acceptance among adolescents.
Contribution to Public Health: This research could show that interventions targeting adolescents may play a critical role in improving public health by reducing the spread of infectious diseases.
Introduction
The World Health Organization (WHO) defines adolescents as individuals between the ages of 10 and 19, a group that constitutes more than 15% of the global population. Psychosocial maturation during adolescence can be divided into three stages: early adolescence (ages 10-14), middle adolescence (ages 15-17), and late adolescence (ages 18-21).
Although most adolescents are healthy, they account for 6% of the global disease and injury burden. Additionally, risk factors for many adult diseases begin or intensify during adolescence. This highlights the importance of adolescent health as a global priority for individual quality of life, future adult health, and societal well-being. Adolescents are particularly vulnerable to infectious diseases, some of which can be prevented through vaccination.
In both the United States (U.S.) and globally, routine childhood immunizations are among the most effective and cost-efficient public health interventions for preventing infectious diseases and early death. In the U.S., more than 100 million cases of vaccine-preventable diseases, such as measles, mumps, rubella, and pertussis, have been prevented. However, adolescents face increased risks of infectious diseases due to biological, behavioral, and environmental factors, making them an important target group for vaccination programs.
Furthermore, childhood and adolescent vaccinations contribute to reducing many preventable diseases while also providing additional health benefits. For example, the HPV vaccine is responsible for preventing approximately 4.5% (640,000 cases) of new cancer cases worldwide. However, HPV vaccination rates among adolescents remain insufficient compared to other vaccines. Factors such as low parent awareness, concerns about vaccine safety, and fears about vaccination increasing sexual activity are key contributors to this issue. Globally, 13.5 million children miss at least one routine vaccine, leading to approximately 1.5 million deaths from vaccine-preventable diseases. Vaccine hesitancy refers to the delay or refusal of vaccination, despite its availability, which negatively impacts immunization efforts.
Vaccination rates for adolescents, especially for Td, flu, and HPV vaccines, are not at optimal levels. Adolescents are at risk for certain vaccine-preventable diseases due to various age-specific behavioral, environmental, and biological factors. For example, recent outbreaks of invasive meningitis in the U.S. primarily occurred on university campuses, where adolescents and young adults live in close proximity and socialize frequently.
Barriers to immunization include limited time, health systems, competing parental priorities, and vaccine hesitancy. Additionally, communication and educational programs are critical to managing vaccine hesitancy in adolescents. These programs should address not only insufficient vaccination coverage for childhood diseases and waning immunity from early childhood vaccination series but also primary vaccination for diseases that specifically affect adolescents. Successful vaccination strategies for adolescents demonstrate the benefits of vaccination through motivational elements and rewards, using age-appropriate, comprehensive, youth-friendly, and evidence-based information and education.
The Health Belief Model (HBM) is a widely used theory to increase vaccine knowledge and vaccination rates. The HBM consists of components such as perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and self-efficacy. This model provides an important framework for understanding the factors that influence individuals' participation in vaccination programs.
Objective: The purpose of this study is to assess how vaccination education, video animation, and game applications, based on the components of the Health Belief Model, affect late adolescents' vaccination decisions. The findings can contribute to the development of targeted interventions to increase vaccine acceptance among adolescents. The importance of vaccination and effective communication strategies play a critical role in achieving adolescent and public health goals.
Research Hypotheses:
The control group will also complete the pre-test on the same day but in a different environment from the intervention group. The control group will continue with their routine training, and on the day the intervention group's post-test is administered, the same questionnaires will be applied to the control group. The data collection process will take about 10-15 minutes. After the research is completed, the control group participants will receive the same vaccination education, video animation, and game application.
Education Material Application: In this research, participants are provided with educational material based on the components of the Health Belief Model (HBM). The material is designed to increase vaccination rates and raise awareness among participants about vaccines. The content is structured around key HBM components, such as perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and self-efficacy.
The educational material aims to inform participants about the risks, benefits, and potential barriers related to vaccination, helping them become more informed about the factors influencing their vaccination decisions. This education is designed to positively influence participants' vaccine acceptance and general attitudes toward vaccines.
Video Animation Application: Participants in this study will be shown a video animation aimed at increasing knowledge and awareness about vaccines. The animation's goal is to explain how vaccines work, how they strengthen the immune system, and to provide information on perceived risks, benefits, and barriers related to vaccination.
The animation will cover topics such as how vaccines affect the body, contribute to the immune system, and influence vaccination decisions. The animation will be about 4 minutes long and will help participants increase their knowledge of vaccines and develop more informed attitudes toward vaccination.
Game Application: Participants will play an "infected interaction" game designed to simulate social interactions and the spread of infectious diseases. The goal of the game is for participants to observe how infected individuals make contact with others and the impact of these interactions on disease transmission.
During the game, two participants will secretly be marked as "infected." These infected individuals will be indicated with a symbol or sign known only to them. The participants will then be asked to socialize freely with others in the group for two minutes. During this interaction, the infected participants will secretly pass on the infection signal to other participants they come into contact with. After the 2-minute interaction, researchers will calculate which participants were infected and whether the infection was passed on to others.
Variables: Independent Variables: Gender, Age, Income Level, School, Presence of Chronic Diseases, etc. Dependent Variables: Scale scores
