Table 1 Example statements for measuring PMT beliefs

From: Spontaneous social distancing in response to a simulated epidemic: a virtual experiment

Perceived severity of illness:  
• If I were to develop an infectious disease (e.g. flu) I would suffer a lot of unpleasant symptoms.  
• Developing an infectious disease would be unlikely to cause me to die prematurely.  
Perceived vulnerability:  
• My chances of developing an infectious disease (e.g. flu) in the future are likely.  
• I am unlikely to develop an infectious disease (e.g. flu) in the future.  
Response efficacy:  
• If I were to engage in social distancing (e.g. by avoiding public transport and social events) I would lessen my chance of developing an infectious disease.  
Self efficacy:  
• I am discouraged from engaging in social distancing during times of infectious disease, because I feel it would be difficult to do so.  
• I feel confident in my ability to engage in social distancing during times of infectious disease.
