VEIGA, Heila Magali da Silva; PASQUALI, Luiz  and  SILVA, Narla Ismail Akel. Validation of the Driver Behavior Questionnarie (DBQ) to Brazil. Aval. psicol. [online]. 2009, vol.8, n.2, pp. 187-196. ISSN 1677-0471.

The goal of this study was to make an adaptation of DBQ (Driver Behavior Questionnaire) to Brazil and verify if the factorial structure of the original study would be confirmed. The questionnaire, comprised by 67 items, named Questionário do Comportamento do Motorista in Portuguese (abbreviation QCM), was applied to a non-probabilistic sampling of 504 drivers from the Federal District, 154 men and 348 women, average age 23, bearing the National Driving License (Carteira Nacional de Habilitação, abbreviation CNH in Portuguese). The factorial analysis showed the existence of three factors, keeping the original study's factorial structure. These factors were named errors (13 items, alpha = 0,80), and the lapses and violations factors (13 items each, alpha = 0,79). The final instrument was comprised by 39 items and explained 26,8% of total variance. We highlight the social relevance of this study, since it provides data that may assist traffic professionals and psychologists in the obtention of tools geared towards the area of traffic planning and education.
