Variable | Number of items | Reliability | Example question |
---|---|---|---|
Intention | 3 | α = .88 | I would be willing to vaccinate people aged 60 years and older against infectious diseases other than influenza. |
Attitude | 2 | r = .64 | I think vaccination as a preventive tool is: 1 = not very useful; 7 = very useful. |
Attitude additional vaccination | 1 | n.a. | Offering additional vaccination other than influenza vaccination to people aged 60 years and older is necessary. |
Attitude vaccination 80+ | 1 | n.a. | Offering people 80 years and older some form of vaccination is still useful. |
Attitude outbreak | 1 | n.a. | Vaccinating people 60 years and older with or without co-morbidities during an outbreak of an infectious disease is always useful. |
Perceived severity (per infectious disease) | 4 | n.a. | How serious do you think are the different diseases for people aged 60 years and older? Influenza/ herpes zoster/ pneumonia/ pertussis: 1 = not severe at all; 7 = very severe. These are four separate items. |
Selection comorbidity over age | 3 | α = .81 | Vaccinating people on the basis of co-morbidities is favored over vaccinating people on the basis of age, irrespective of the infectious disease. |
Prevention | 1 | n.a. | In general, prevention of illness has the preference over cure. |
Prevention mortality | 1 | n.a. | Additional vaccines should primarily be focused on the prevention of death. |
Prevention morbidity | 1 | n.a. | Additional vaccines should primarily be focused on the prevention of illness |
Usefulness health benefits | 1 | n.a. | In the consideration to offer vaccination, individual health benefits are more important than cost-effectiveness on the population level. |
Intention (per infectious disease) | 3 | n.a. | I would recommend healthy people in their 60s to get vaccinated against pneumococcal disease/ herpes zoster/ pertussis. These are three separate items. |
Intention comorbidity (per infectious disease) | 3 | n.a. | I would recommend people in their 60s who have a comorbidity to get vaccinated against pneumococcal disease/ herpes zoster/ pertussis. These are three separate items. |
