Some scholars choose to measure risk perception based on a single dimension, such as the intensity of residents' overall feeling (He and Zhai 2015), the degree of threat to family assets and personal security (Lindell and Hwang 2008; Calvello et al. 2016), or the future possibility of a hazard occurring (Butler and DeChano 2012).
For example, the items measuring risk perception should correlate more strongly with each other than with the items measuring affect.
Researchers have begun exploring approaches to measuring risk perception in other domains such as skin cancer [ 12] and influenza vaccination [ 27], however, there is a lack of research examining how best to measure perceived risk for HIV infection.
The empirical results of studies on risk perception and disaster preparedness are not consistent due to the different measures used to assess risk perception (Xu et al. 2016, 2017a; Peng et al. 2017).
A total of eight measures were used to assess risk perception.

Although there is already a large number of studies that have measured household risk perception via the psychometric paradigm method, different scholars still hold different views about household risk perception (Xu et al. 2016).
The concepts measured were risk perception of EMF in general, risk perception of different EMF sources, positive and negative feelings towards EMF in general and of different EMF sources, and concerns about health effects of EMF.
We used likelihood and severity to measure the risk perception levels by asking: how likely do you think a Natech accident would be a threat to your life or property: 1 (very unlikely) to 5 (very likely) before the quake, just after the earthquake shaking, and in the next 10 years.
