The aim of the present study was to investigate time-across stability of different factor solutions (two to six factors) of the Driver Behaviour Questionnaire (DBQ) and to examine the changes on self-reported driving pattern in a follow-up sample (n = 622) after three years of the first responses. Repeated measures ANOVA indicated that there was a significant change between Time 1 and Time 2 scores in six items of the DBQ. Drivers reported less competitiveness while driving at Time 2 but more speeding, drinking and driving, driving to wrong destinations and having no recollection of the road just travelled. Significant Time x Sex x Age interactions were found in change scores of four items. Young males and middle-aged female drivers emerged as a group of drivers who changed their self-reported driving pattern over three years. Additionally, sex, age or both had main effects on scores of 21 items. Males and young drivers reported more violations than females and older drivers, whereas female drivers reported more errors and lapses. After running possible factor solutions with Tucker's Phi agreement coefficients, the results indicated that the four- and two-factor solutions were the most stable and interpretable ones. The two-factor solution showed better time-across stability than the four-factor structure did, although the factor solutions found at Time I and Time 2 were not as identical as expected. Separate analysis revealed that drivers who had high annual mileage at Time I and Time 2 showed the strongest two-factor time-across stability. The test-retest reliability was 0.50 for errors, 0.76 for violations and 0.61 for the whole scale.

Personality and Behavioral predictors of traffic accidents Testing a contextual mediated model Sümer, Nebi (Elsevier BV, 2003-01-01) A contextual mediated model was proposed to distinguish the distal (i.e. personality factors) and proximal (i.e. aberrant driving behaviors) factors in predicting traffic accident involvement. Turkish professional drivers (N=295) answered a questionnaire including various measures of personality factors, driver behaviors, and accident history. Results of the latent variable analysis with LISREL indicated that latent variables in the distal context (i.e. psychological symptoms, sensation seeking, and aggress...
Can the traffic locus of control (T-LOC) scale be successfully used to predict Swedish drivers' speeding behaviour? WARNER, Henriette Wallen; Özkan, Türker; Lajunen, Timo (Elsevier BV, 2010-07-01) The first aim of the present study was to examine the factor structure of the traffic locus of control (T-LOC) scale in a Swedish sample of drivers. The second aim was to examine if this scale can be used to predict drivers' speeding behaviour. A sample of Swedish car owners (N = 223) completed a questionnaire including questions based on the traffic locus of control (T-LOC) scale as well as questions about their speeding behaviour. The results showed a five factor solution including own skills, own behavio...
The Manchester Driver Behaviour Questionnaire: a cross-cultural study Lajunen, T; Parker, D; Summala, H (Elsevier BV, 2004-03-01) The aim of the present study was to investigate if the original factorial structure of the Manchester Driver Behaviour Questionnaire (DBQ) was replicated in Finland and The Netherlands. A postal questionnaire survey of drivers was carried out in Britain, Finland and The Netherlands. Exploratory factor analysis together with target (Procrustes) rotation and factorial agreement indexes were calculated to investigate the applicability of Finnish and Dutch versions of DBQ. Results of the factor comparisons show...
Cross-cultural differences in driving skills: A comparison of six countries Özkan, Türker; El. Chliaoutakis, Joannes; PARKER, D; SUMMALA, H (Elsevier BV, 2006-09-01) The first aim of the present study was to investigate the applicability of the two-factor structure (perceptual-motor skills by 11 items, e.g., "fluent driving"; safety skills by 9 items, e.g., "conforming to the speed limits") of the Driver Skill Inventory (DST) among British, Dutch, Finnish, Greek, Iranian, and Turkish drivers. It was also hypothesized that the combination of self reported high ratings of perceptual-motor skills and low ratings of safety skills creates a serious risk for dangerous driving...
Cross-cultural differences in drivers' speed choice WALLEN WARNER, H; Özkan, Türker; LAJUNEN, TIMO JUHANI (Elsevier BV, 2009-07-01) The aim of the present study was to examine if there are any cross-cultural differences between Swedish and Turkish drivers' rating of the variables in the theory of planned behaviour (TPB) with regard to complying with the speed limit. A sample of 219 Swedish and 252 Turkish drivers completed a questionnaire including questions based on the theory of planned behaviour (i.e. regarding attitude, subjective norm, perceived behavioural control, intention and behaviour). The results show that country difference...
