Driving anger: correlates and a test of state-trait theory

A survey and field study evaluated predictions from state-trait theory applied to driving anger. Trait driving anger, the propensity to become angry when driving, correlated positively with anger in frequently occurring driving situations and in day-to-day driving and with aggressive and risky behaviors while driving. Although not correlated with crash rates or moving violations, trait driving anger correlated with crash-related conditions such as loss concentration, loss of vehicular control, and close calls. Results generally supported predictions from state-trait theory and the construct validity of the Driving Anger Scale, as well as mapping correlates of the disposition to become angry while driving.
