Couple similarity for driving style

Though gender differences in driving habits and behaviors are well documented, the similarity between couples for such behaviors has received little or no attention. This study examined the associations between 413 pairs of intimate partners who completed the multidimensional driving style inventory, a self-report scale which assesses four broad domains of driving style. Significant associations were found between couples' driving styles. Moreover, significant correlations were found between self- and partner-reports, indicating a high reliability for self-report in this context. The discussion focuses on the importance of examining intra-familial associations in driving styles as a basis for planning and designing effective safety interventions.
