Driver Social Desirability refers to positive biased self-descriptions given by drivers. As it could affect self-reported results, its assessment is necesary. The present study analyzes the psychometric properties of the Driver Social Desirability Scale (DSDS) in an Argentine sample. A sample of 332 drivers from Mar del Plata city was collected in different administration conditions. Participants answer a descriptive socio-demographic questionnaire, driving style measures (MDSI), and personality measures (ZKPQ-50) under four different administration conditions. A 2x2 quasiexperimental factor design was used to assess possible effects of social desirability bias. The first manipulated factor was type of administration (self-administration vs. face-to-face administration). The second manipulated factor was the anonymity of responses (anonimous vs. non- anonimous conditions). Results indicated good overall properties for the argentinean version of the DSDS. Evidence on the external and internal validity of DSDS was also gathered. However, results obtained suggest that DSDS could assess a extremely careful and law abiding driving style besides driver social desirability.
