Anger amongst Turkish drivers: Driving Anger Scale and its adapted, long and short version

Driver Anger Scale (DAS) Among Car Drivers: How Serious Are They?

“…Furthermore, the factor that was found to be least provoking was police presence, which had the lowest average anger rating (M=2.08, SD=0.78) of the six factors. This finding is inline with a previous study that reported, the presence of police did not evoke any appreciable amounts of anger amongst their sample of Turkish and Malaysian drivers [11,12]. Table 2.…”

“…Based on a previous study the DAS was found to be related to trait anger scale with a strong correlation coefficient [10,13]. Another research, Yasak and Esivol [11] stated that the correlations between anger symptoms and the six factors of DAS have positive correlation and were significant among the factor DAS, except for illegal driving. Table 5 shows the model summary of multiple regression analysis conducted for driver anger.…”

The expression of anger amongst Turkish taxi drivers

“…The scale presents 14 different situations and asks participants to rate how angry each situation makes them feel on a five point scale (1 = not at all, 5 = very much). This scale had also previously been translated into Turkish (Yasak and Eş iyok, 2009) and that version of the DAS was used here. The eight violation items from the Driving Behaviour Questionnaire (DBQ; Reason et al, 1990) were used to measure risky driving behaviour.…”

Psychometric adaptation of the driving anger expression inventory in a Chinese sample

“…To develop a short version of the DAX that has a satisfactory reliability and stable internal structure, we revised this scale based on the item-total correlation coefficients (ITCs) for each subscale (Inoue et al, 2014;Stanton, Sinar, Balzer, & Smith, 2002;Yasak & Esiyok, 2009). The 5 items with the highest ITCs in each subscale were selected to compose the revised version of the DAX with 20 items.…”
