Psychometric evidence of the Brazilian version of Driving Cognitions Questionnaire (DCQ)

This paper examined the psychometric data obtained by the Brazilian version DCQ (Driving Cognitions Questionnaire) and its convergence with DBS (Driving Behavior Survey). The research included 187 participants of both genders, aged between 19 and 79years (mean 34years), with driving license in category 'B' (cars). The internal consistency obtained by research (Cronbach's alpha) was α=0.96 for full DCQ; α=0.89 for the subscale panic in the direction, α=0.91 for the subscale of concern in causing accidents and α=0.92 for the subscale of social concern. Psychometrically the results are positive and confirm the relevance of using the instrument. The survey also found positive convergence (although less pronounced) with the DBS, which is another instrument that comes to difficulties when driving or dealing with traffic or driving a car. Thus, this article demonstrates psychometric results that point to the profitable use of the Brazilian version of DCQ as an adjunct in the diagnosis of difficulty in driving.
