Reliability and validity of scale measuring motorcyclists’ risk perception: The case study of Hanoi, Vietnam

Abstract

The purposes of this study are to test and verify a risk perception scale among Vietnamese motorcyclists using Cronbach's Alpha coefficient, Exploratory Factor analysis (EFA), and Confirmatory Factor Analysis (CFA) through a self-reported questionnaire. The risk perception scale is established to measure the risk perception of motorcyclists in Hanoi. The scale consists of 14 items, which are divided into three factors: Worry and Concern, Probability Assessments, and Cognition of Danger level. These factors can explain 71.586% of the variation. The factor loadings of items all meet the requirements of the tests. The risk perception scale has good reliability and validity and can be used to measure the risk perception of Vietnamese motorcyclists. The results of this study can inform the future study of risk perception and risky behaviors of Vietnamese motorcyclists.
