Part 2 of the questionnaire consisted of an 18-item scale
measuring the respondent’s perceptions of the risks associated
with a number of potential causes of motorcycle
accidents (Appendix 1). These items have been validated
and demonstrate high internal consistency among the subscales
(Cronbach’s alpha Z .742e.898). The scale assesses
the perceptions of Chinese motorcyclists (Cheng & Ng,
2012) of the risk associated with the potential causes of
traffic accidents grouped along three dimensions (driving,
environmental, and belief related). The participants were
asked to indicate whether or not they thought each risk was
a cause of accident using a 5-point Likert scale ranging from
1 (strongly disagree) to 5 (strongly agree).
