The Romanian version of the multidimensional driving style inventory: Psychometric properties and cultural specificities

The multidimensional driving style inventory (MDSI), assessing four broad dimensions of driving styles, was originally built in Israel. In line with other previous adaptations of this instrument in different cultural contexts (such as Argentina), our research aimed to develop a valid and reliable Romanian version of the MDSI and to evaluate its external and construct validity. We conducted two studies aimed at this objective. Study 1 (n = 1237) first tested the factorial adequacy of the previous MDSI versions in our Romanian sample. Then, the culture-specific version of the MDSI that emerged from the factor analysis was examined in terms of its structure, internal consistency, item proprieties, and associations to socio-demographic variables and self-reported traffic crashes and offenses. Study 2 (n = 835) examined the associations between the driving styles assessed by this newly developed measure and several relevant personality traits: sensation seeking (both general and in traffic), desire for control, driving anger, normlessness, dutifulness and frustration discomfort. The results of the two studies support the validity and reliability of this culture-specific version of the MDSI. In comparison to the previous versions, the Romanian MDSI version addresses a supplementary driving style, concerning the violation of rules perceived as irrational in the respective situation. The reasons for the emergence of this distinct driving style in the Romanian driving context, as well as its relationships to the high traffic crashes rate in this country are discussed.
