A study of contemporary modifications to the Manchester Drivers Behaviour Questionnaire for organizational fleet settings

The Manchester Driver Behaviour Questionnaire (DBQ) is increasingly becoming one of the most prominent measurement scales to examine self-reported driving behaviours (Lajunen & Summala, 2003). For example, the DBQ has been extensively utilised in a range of driver safety research areas, such as: age differences in driving behaviour (Dobson et al., 1999), the genetics of driving behaviour (Bianchi & Summala, 2004), cross cultural studies (Lajunen et al., 2003) as well as factors contributing to accident involvement (Dobson et al., 1999; Meksen, Lajunen & Summala, 2002; Parker et al., 1995) and demerit point loss (Davey et al., 2007). Furthermore, the versatility of the DBQ has also been demonstrated via the utilisation of the instrument in a number of countries, including China (Xie & Parker, 200), Australia (Davey et al., 2006; Dobson et al., 1999; Newnam, Watson & Murray, 2004), New Zealand (Sullman, Meadows & Pajo, 2002), Finland (Bianchi & Summala, 2004; Mesken et al., 2002), and the United Kingdom (Parker et al., 1995; Parker et al., 2000)
