An Integrating PLS-SEM and DEMATEL Based Grey Theory Model to Investigate Individuals’ Vaccination Intention Against COVID-19
Description
The main objective of this study is to comprehensively investigate individuals’ vaccination intention against COVID-19 during the second wave of COVID-19 spread in Vietnam using a two-stages approach. - Decision-Making Trial and Evaluation Laboratory based on Grey Theory (DEMATEL-G) was employed to explore the critical factors of vaccination intention among individuals. - Partial Least Squares- Structural Equation Modeling (PLS-SEM) was applied to test the hypotheses of individual behavioral intention to get the vaccine to prevent the outbreak of COVID-19 via Smart-PLS 3.3.3 software. - A panel data of 661 valid respondents was collected from June 2021 to July 2021 and confidentiality was maintained for all data obtained.

- To review the critical factors influencing Vaccination intention against COVID-19 based on the Protective motivation theory ( PMT) and the theory of planned behavior (TPB) - Apply DEMATEL based Grey theory model to determine the influence degrees and directions of all factors, as well as the network structures of all factors - PLS-SEM was used to analyze the causal relationships among dimensions, cause and effect diagrams
