Summary
The theory of planned behavior (TPB) framework effectively predicts COVID-19 vaccination intention, with attitude being the strongest predictor. Understanding these factors can enhance public health campaigns for vaccine uptake.
Area of Science:
- Behavioral Science
- Public Health
- Epidemiology
Background:
- COVID-19 vaccination intention is crucial for pandemic control.
- The Theory of Planned Behavior (TPB) offers a framework to understand health-related intentions.
- Systematic analysis of TPB constructs' influence on COVID-19 vaccination intention is needed.
Purpose of the Study:
- To systematically analyze the literature on the Theory of Planned Behavior (TPB) and its constructs' influence on COVID-19 vaccination intention.
- To quantify the association between TPB constructs (attitude, subjective norms, perceived behavioral control) and vaccination intention.
- To explore variations in these associations across different geographic regions and populations.
Main Methods:
- Systematic literature review following PRISMA guidelines.
- Inclusion of quantitative studies from major databases (PubMed, CINAHL, Web of Science, Google Scholar).
- Meta-analysis to pool effect sizes of TPB constructs on COVID-19 vaccination intention.
Main Results:
- The average COVID-19 vaccination intention rate was 73.19%.
- Attitude showed the strongest association (r=0.487), followed by subjective norms (r=0.409), and perceived behavioral control (r=0.286).
- Effect sizes varied by region and population; perceived behavioral control was dominant in Africa among patients.
Conclusions:
- The Theory of Planned Behavior (TPB) is a valuable framework for predicting COVID-19 vaccination intention.
- Public health initiatives should leverage TPB constructs to design effective vaccination promotion programs.
- Tailoring interventions based on regional and demographic factors is recommended for optimizing vaccine uptake.

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

613
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

11.9K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
