Recently, the government has loosened one of the health protocols, namely the wearing of masks. However, many people still wear masks, even though the regulations have been relaxed. Perception of the risk of being infected with COVID-19 and self-control are two predictors of the community continuing to implement health protocols after the COVID-19 vaccination. This study aims to determine the relationship and influence between risk perception and self-control on preventive behavior carried out after the COVID-19 vaccination. Respondents in this study totaled 312 people with the criteria of having been vaccinated against COVID-19, having an age range of 19-45 years, and being domiciled in JABODETABEK. This study collected data by distributing online questionnaires in the form of Google Forms. The study used a quantitative approach using the purposive sampling technique. The scales used in this study are COVID-19 Risk Perception, Brief Self-Control Scale (BSCS), and Preventive Behavior Scale, and analysis using Pearson Correlation and Hierarchical Multiple Regression. The results of the study obtained R squares of 0.071 and 0.137 (P < 0.01), which means that risk perception has a significant positive effect on preventive behavior by 7.1%, and when risk perception is interacted with self-control together, the results show that both affect preventive behavior by 13.7%, and the remaining 86.3% is influenced by other variables not studied. The recommendations in this study encourage the community to perceive that COVID-19 still has risks that can attack health conditions and to continue to control themselves to maintain health so that people can be encouraged to vaccinate.
