The Driver Behavior Questionnaire (DBQ) is one of the most widely used instruments for measuring self-reported driving behaviors. Despite the popularity of the DBQ, the applicability of the DBQ in different driver groups has remained mostly unexamined. The present study measured aberrant driving behavior using the original DBQ (Reason, J.T., Manstead, A., Stradling, S.G., Baxter, J., Campbell, K., 1990. Errors and violations on the road - a real distinction. Ergonomics, 33 (10/11), 1315-1332) to test the factorial validity and reliability of the instrument across different subgroups of Danish drivers. The survey was conducted among 11,004 Danish driving license holders of whom 2250 male and 2190 female drivers completed the questionnaire containing background variables and the DBQ. Exploratory and confirmatory factor analysis showed that the original three-factor solution, a four-factor solution and a two-factor solution had acceptable fit when using the whole sample. However, fit indices of these solutions varied across subgroups. The presents study illustrates that both the original DBQ and a Danish four-factor DBQ structure is relatively stable across subgroups, indicating factorial validity and reliability of the DBQ. However, as the Danish DBQ structure has an overall better fit, the present study highlights the importance of performing an explorative analysis when applying the DBQ in order to assess the problem areas within a driving population.


The driver behaviour questionnaire in Arab Gulf countries: Qatar and United Arab Emirates
BENER, Abdulbari; Özkan, Türker; Lajunen, Timo (2008-07-01)
Manchester Driver Behaviour Questionnaire (DBQ) is one of the most widely used instruments for measuring self-reported driving style and investigating the relationship between driving behaviour and accident involvement. In spite of the fact that Arab Gulf countries have a higher road accident fatality rate compared to European countries and USA, the DBQ has not been used in Arab countries so far. The aim of the present study was to investigate the factor structure of the DBQ, then to examine the relationshi...
Short and user-friendly: The development and validation of the Mini-DBQ
Martinussen, Laila M.; Lajunen, Timo; Moller, Mette; Özkan, Türker (2013-01-01)
The Driver Behavior Questionnaire (DBQ) is used to measure aberrant driver behavior by asking drivers how often they engage in various aberrant driver behaviors. Since the development of the original DBQ several modified versions have been developed. The difference between the various versions is that new items are added or existing items modified or excluded. However, despite the differences, all versions are relatively long and therefore time-consuming and tiring to answer, which might limit the usability...
A new addition to DBQ: Positive Driver Behaviours Scale
Özkan, Türker (Elsevier BV, 2005-7)
The aims of the present study were to develop an instrument for measuring "positive" driver behaviours and to investigate the relationship between these behaviours, DBQ scales (violations and errors), aggression, traffic offences, and accidents. Participants were 306 Turkish drivers (194 male and 112 female) who completed a questionnaire including the newly developed Positive Driver Behaviour Scale, Driver Behaviour Questionnaire (DBQ), Driver Aggression Indicators Scale (DAIS), and items related to drivers...
Development of the professional driver behavior questionnaire
Yılmaz, Şerife; Öz, Bahar; Özkan, Türker; Department of Psychology (2018)
The aim of the present study was to develop a comprehensive scale measuring professional drivers' driver behaviors. For this reason, a semi-structured interview form was prepared and applied to different professional driver groups in order to collect behavioral examples displayed in traffic context (Study 1). These examples were grouped based on Reason's taxonomy of human error and Professional Driver, Driver Behavior Scale (PDBQ) was developed. PDBQ along with some other behavior scales such as ODBQ and DB...

Driving skills and driving behaviors, as being the human factors in driving, are the most studied and most influential variables of efforts to sustain a safe traffic environment. Although these factors were investigated in the literature and their relationships with different variables and each other are examined in various studies with various samples; anxiety-related factors have always been evaluated only within limited (avoidant) or clinical groups. However, anxiety, like anger, is a negative emotional ...
