Attitudes toward influenza vaccination including the means and standard deviations (SD) for items and scales, the percentage who agreed with each item, and the crude odds ratio (COR) and confidence interval (CI) of vaccination for those who agreed, among 460 unvaccinated and 1084 vaccinated healthcare personnel during the 2010–2011 influenza season.

| Perceived susceptibility itemc | 1 | Imagine that the flu vaccine for this year is unavailable and you are therefore unable to get the vaccine. If you do not get a flu vaccination, what do you think your chance of getting the flu this year will be? | 3.0 (1.2) | 5.3% | 4.0 (1.2) | 24.7% | 6.0 | (3.9–9.2) |

| Concerns about vaccine itemse | 3 | The flu vaccine could give me the flu | 2.7 (1.3) | 28.7% | 1.9 (1.1) | 10.2% | 0.3 | (0.2–0.4) |
| 4 | Systemic adverse effects from the flu vaccine are rare (reverse scored) | 3.4 (1.1) | 46.3% | 3.8 (1.0) | 64.4% | 2.1 | (1.7–2.6) | |

| 6 | I am concerned that there may be something that I do not know about the flu vaccine | 2.6 (1.3) | 26.3% | 2.3 (1.1) | 16.6% | 0.6 | (0.4–0.7) | |
| 7 | I trust guidelines by the CDC and the US Advisory Committee on Immunization Practices that recommend that all health care workers get an annual influenza vaccination (reverse scored) | 3.5 (1.2) | 50.7% | 4.4 (0.9) | 86.0% | 6.0 | (4.6–7.7) | |
| Concerns about vaccine scale | Sum of items 3–7 (range 5–25) | 13.5 (4.1) | 10.1 (3.5) | |||||
| Emotional benefits of vaccination itemse | 8 | With no flu vaccination, I would feel that I am going to get the flu this year | 2.0 (1.1) | 10.5% | 3.0 (1.2) | 35.8% | 4.8 | (3.5–6.6) |
| 9 | With no flu vaccination, I would feel very vulnerable to the flu | 2.2 (1.2) | 14.8% | 3.4(1.2) | 55.4% | 7.1 | (5.3–9.5) | |
| 10 | If I do not get a flu vaccination, I will regret it | 2.0 (1.2) | 13.1% | 3.3 (1.3) | 46.9% | 5.9 | (4.4–7.9) | |
| 11 | If I do not get a flu vaccination and end up getting the flu, I would be mad at myself for not getting the vaccine | 2.3 (1.4) | 24.5% | 3.5 (1.4) | 58.3% | 4.3 | (3.4–5.5) | |

All student t-tests comparing means of items and scale scores between vaccinated and unvaccinated HCP were statistically significant (p < .001).
Crude odds ratio (COR) compares the odds of vaccination among those who agree with the attitude compared to those who disagree.
Options for susceptibility (item 1): 1 = almost zero chance, 2 = very small chance, 3 = small, 4 = moderate, 5 = large, 6 = very large chance, 7 = almost certain; agree = 5 (large) or greater.
Options for vaccine effectiveness (item 2): 1 = not at all effective, 2 = not too effective, 3 = somewhat effective, 4 = very effective; agree = 3 (somewhat) or 4 (very effective).
Options for items 3–12: 1 = strongly disagree, 2 = mildly disagree, 3 = neutral, 4 = mildly agree, 5 = strongly agree; agree = 4 (mildly) or 5 (strongly agree).
