FACTOR CLASSIFICATION AND GROUPING OF AWARENESS BEHAVIOR TOWARDS VACCINATION COVID-19 EPIDEMIC (COVID-19) OF THE ELDERLY IN BANG KHAE

Abstract

The objectives of this research are to analyze the main factors and grouping awareness behaviors on the vaccination against the epidemic of COVID-19 (COVID-19) of the elderly in Bangkok and its vicinity which the study sample It was a group of 400 elderly people aged 60 years and over in Bang Khae area, using a simple randomized method to collect the questionnaire characteristics that consisted of Awareness of the COVID-19 Pandemic defensive behavior and preparation before vaccination. In the study of the behavior of the samples, the frequency distribution method was used and the percentage of the answers received. For factor analysis of all 9 aspects of the principal component analysis with orthogonal rotation by Varimax method is used to extract the common components with the eigenvalues greater than or close to 0.5. The extracted components are then clustered using the K-Means technique.

              The results showed that the sampling was aware that only one person infected with COVID-19 could transmit it to others, on average 2-4. Patients tended to have cough, fever, sore throat, breathlessness, chest tightness. to the point of death. Especially those with underlying diseases are at greatest risk. The main components of awareness were divided into 5 aspects: infection likelihood (Eigenvalues = 2.371 and Variance = 26.341 %), hygiene (Eigenvalues = 1.939 and Variance = 21.540 %), vaccine benefits (Eigenvalues =1.007 and Variance = 11.183 %), risk (Eigenvalues = 0.871 and Variance = 9.676 %), and obstacles to Vaccination (Eigenvalues = 0.750 and Variance = 8.338 %). The clustering from factor extraction It can be divided into 2 groups which are those who focus considering the severity of the Covid-19 virus (99.75 %) and those who focus considering vaccine efficacy (0.25 %). Therefore, both public and private agencies involved should focus more concretely on creating an understanding of both the virulence of virus and efficacy of the vaccine received.
