Analysis of the Fourth Vaccination Intention of the Elderly for COVID-19 Based on RPA Theory

Abstract

With the open management of the epidemic in China, the first wave of the epidemic has passed, and the safety and health of the elderly have become a key concern in the face of the uncertain epidemic situation in the future. This study was conducted to analyze whether children would give their elderly family members a fourth dose of the Covid-19 vaccine, in addition to the third dose of the vaccine, in view of the fact that the elderly may have underlying diseases and their body functions are aging. This study uses the Risk Perception Attitude (RPA) framework to analyze not only the impression and credibility of the children in the family, but also the children's risk perception and self-efficacy and, thus, their willingness to allow their parents to receive the vaccine. Based on the questionnaire of "Elderly people receiving the fourth dose of the Covid-19 vaccine" in 2023, four seven-level scales were developed for each of the four variables, and the data were collected and analyzed for reliability and validity, and regression analysis was designed to gauge the behavior of the children in determining whether or not to vaccinate the elderly in their families under the influence of information media. It was found that media impression was deeply and positively related to risk perception and self-efficacy; media credibility was also profoundly and positively related to risk perception and self-efficacy; risk perception and self-efficacy had a significant effect on the final behavioral outcome.
