Abstract

The study aims to determine the logistic regression equation to predict among older adults


whether to receive the COVID-19 vaccination or not. The study population comprised 272 respondents who were above 60 years of age and resided in Chanthaburi Province. Using multi-stage cluster sampling, the data were gathered via paper and online platforms. Structured questionnaire based on the components of theory of planned behavior to assess the attitudes towards COVID-19 vaccine, subjective norm, perceived behavioral control, and COVID-19 vaccination intention. The results of content validity index (CVI) showed between 0.87-1.00, the reliability value of the alpha coefficient of Cronbach is between 0.80-0.84. Then Binary logistic regression was employed to analyze the data by using Enter method.There are 6 significant variables associated with the COVID-19 vaccine decision making for older adults as follows: 1) The belief that an elderly person needs a vaccination. 2) The belief that if people obtain the vaccine, their lives would return to normal. 3) Influence of family members 4) Medical professionals’s recommendation. 5) The belief in the effectiveness of vaccines.  6) The belief lowering the chance of getting severe COVID-19.  The model could predict overall correctly at 84.6% with Cox & Snell R2 = 0.502 and Nagelkerke R2 = 0.736. It could account for the COVID-19 vaccine intention's variation, which is 50.2% and 73.6%, respectively.
