High anger drivers acknowledging problems with driving anger and interest in counseling (high anger/problem [HP] drivers) were compared with high and low anger drivers not acknowledging problems with driving anger and seeking counseling (high and low/nonproblem [HNP and LNP, respectively] drivers). High anger groups reported more anger while driving; aggressive expression of driving anger; aggression and risky behavior; trait anger; impulsiveness; and aggressive, less controlled forms of general anger expression and less adaptive/constructive coping than LNP drivers. HP drivers received more tickets and experienced more minor accidents than LNP drivers. Although high anger drivers did not differ on reported anger, risky behavior, and impulsiveness, HP drivers reported greater aggression on 1 measure, greater aggressiveness on 3 measures of driving anger expression, greater trait anger, and more aggressive and less controlled forms of general anger expression, suggesting HP drivers are somewhat more aggressive than the HNP group. Results supported the state-trait model of anger. Implications for intervention were drawn.
Tested hypotheses from state-trait theory applied to anger while driving. College student drivers high in trait driving anger were compared to drivers low in trait driving anger. High anger drivers were more frequently angered in day-to-day driving (frequency hypothesis). They reported more intense anger in their most angering driving situations, when visualizing provocative driving events, and in day-to-day driving (intensity hypothesis). Driving diaries and surveys showed they engaged in more aggressive behavior and expressed their anger through more verbal, physical, and vehicular means (aggression hypothesis). They reported handling of their anger less well when visualizing provocative events and on the Adaptive/Constructive Expression scale (reduced adaptive expression hypothesis). They engaged in risky behavior (risky behavior hypothesis) and experienced more moving violations, close calls, and losses of concentration, but not more major or minor accidents (partial support for crash-related outcomes hypothesis). High anger drivers were more generally angry and impulsive and employed more negative, less controlled forms of general anger expression. Results supported state-trait theory and added to the literature showing that high anger drivers have some other psychological and behavioral characteristics that may interact negatively with anger behind the wheel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
