“…The scale comprised of twenty items which were selected from five existing driving behavior scales, including the Driver Behavior Questionnaire (DBQ; Parker, Lajunen, & Stradling, 1998), Driver Anger Expression Inventory (DAEI; Deffenbacher, Lynch, Oetting, & Swaim, 2002), the Driving Angry Thoughts Questionnaire (DATQ; Deffenbacher, Deffenbacher, Lynch, & Richards, 2003), and the Driver Anger Scale (DAS; Deffenbacher, Oetting, & Lynch, 1994). From the factor analysis, six factors were obtained: anger/aggression, absentmindedness, speeding/minor infractions, judgment of other drivers, overt expression and misc (Brill & Mouloua, 2011). The predictive validity of this questionnaire was tested in a simulated environment indicating aggressive behavioral measurements were significantly correlated with the composite score of the ADBQ (Brill, Mouloua, Shirkey, & Alberti, 2009).…”
