4.2. Participants’ Intention to Exhibit Protective Behaviors
| Drivers, Barriers, and the Reasons | Theoretical Basis | No. (%) |
|---|---|---|
| Reasons for accepting protective behaviors | ||
| I want to prevent that I transfer COVID-19 to people around me. | Perceived susceptibility | 1850 (72.5) |
| COVID-19 can be serious. | Perceived severity | 1724 (67.6) |
| I feel responsible for my health. | Perceived susceptibility | 1673 (65.6) |
| I want to prevent contracting COVID-19. | Perceived susceptibility | 1605 (62.9) |
| I trust that the measures help. | Perceived benefits/Coping appraisal | 1347 (52.8) |
| Reasons for denying protective behaviors | ||
| SOD; Total number: 579 | ||
| Because I don't want others to feel that I have disrespected them. | Attitude towards the behavior | 219 (37.8) |
| Because I have received little information about its importance. | Perceived behavioral control | 175 (30.2) |

| Because these actions are difficult and takes too much effort (time, cost etc.). | Perceived costs | 63 (6.9) |
| GHH; Total number: 51 | ||
| Because I'm not used to doing it. | Perceived behavioral control | 5 (9.8) |
