Adaptation and validity of the multidimensional driving styles inventory for the Malaysian drivers

This paper aims to classify Malaysian drivers’ driving styles (DS) using the Multidimensional Driving Styles Inventory (MDSI). Previously, an MDSI study was performed in Malaysia but was not carried out using the native language. In this study, 430 respondents participated, and the MDSI data were analyzed using exploratory factor analysis (EFA). The Malaysian driving style profile distribution was then determined using the three methods: sum scores by the factor, weighted sum scores, and Barlett’s method. Besides, the differences between the sociodemographic variables for the proposed driving styles were also reported. The results revealed five Malaysian driving style factors: careful, risky, angry-impatient, dissociative, and anxious. The sociodemographic variables’ results significantly affect careful, risky, angry-impatient, and anxious driving styles. This study indicates that Malaysian MDSI provides valid measures and useful instruments to classify the types of driving styles in Malaysia.
