Alternative Abstract
This study is a descriptive research investigation to identify the relationship between university students' COVID-19 knowledge, vaccine knowledge, health beliefs, self-efficacy, cues to action, and vaccination intentions and to identify influencing factors of vaccination intentions.
The subjects of this study were 164 students attending University A located in Suwon-si, Gyeonggi-do, and data were collected via Google Forms from June 21 to July 17, 2021. The COVID-19 knowledge of the subjects was measured using the tool developed by Kim Jin-hee et al. (2021) to measure the COVID-19 knowledge of university students, and their vaccine knowledge was measured using the tool that is derived from the vaccine knowledge scale developed by Zingg and Siegrist (2012) and translated by the researcher. In addition, in order to measure the perceived susceptibility, the perceived severity, the perceived benefits, the perceived barriers, and the cues to action for COVID-19, the translation and modification version of Health Belief Model Applied to Influenza (HBMAI) developed by Erkin and Özsoy (2012) that is conducted by Shin Sun-hwa (2019) was adapted to suit the purpose of this study. Also, for measuring the self-efficacy, the tool developed by Gerent and Shepherd (2012) was translated and modified to suit the purpose of this study, and to measure the vaccination intention, the tool developed by the Ko Ji-ha-na (2011) and modified by Kim Young-hee et al. (2017) was used to fit the purpose of this study. The collected data were analyzed using the SPSS/WIN 25.0 program.
The main results of the study are as follows.
1. The average age of the subjects was 22.8 years old, and 76 subjects (46.3%) were male. Thirty-two (19.5%) subjects were vaccinated against the influenza, and 29 subjects (17.7%) had COVID-19 patients nearby.
2. The COVID-19 knowledge of the subject averaged 12.63±1.38 out of 16 points, the vaccine knowledge was 4.74±1.95 out of 9 points, and the perceived susceptibility was 30.11±4.94 out of 40 points. Also, the perceived severity was 16.07±3.20 out of 20 points, the perceived benefits 19.86±4.03 out of 30 points, the perceived barriers 19.18±5.49 out of 40 points, and the self-efficacy 15.80± 3.38 out of 21 points. In addition, the cues to action were 7.30±2.38 out of 15 points, and the vaccination intention was found to be 12.26±2.13 out of 16 points.
3. There was a statistically significant difference in the vaccination intention according to the general characteristics of subjects depending on whether or not they were vaccinated against influenza (t=2.21, p=.029).
4. The subject's vaccination intention had a statistically significant positive correlation with the perceived severity (r=.19, p=.015), the perceived benefits (r=.20, p=.012), and the self-efficacy (r=.61, p<.001). And, the perceived barriers (r=-.41, p<.001) and the cues to action (r=-.16, p=.037) showed a statistically significant negative correlation.
5. The hierarchical regression analysis was performed to identify the factors affecting the subject's vaccination intention. As a result, in Model I, the presence or absence of influenza vaccination (β=.17, p=.029), and the explanatory power of the model was 2.9% (corrected explanatory power 2.3%). Next, in Model II, the perceived severity (β=.12, p=.048), the self-efficacy (β=.50, p<.001), and the cues to action (β=-.15, p=.019) were significant variables. The explanatory power of the model was 43.0% (adjusted explanatory power 40.9%) (F=19.77, p<.001).
Based on the above research results, it was confirmed that it is important to increase the perceived severity and form the correct attitude toward the infectious diseases by strengthening the education so that the seriousness of the disease among young college students. In addition, the enhancing self-efficacy intervention should be develped and implemented to increase college students' intention to be vaccinated against COVID-19 and further increase the vaccination rate.
